As Windows 10 delay continues, support shortfall grows

Leave a comment

Microsoft is running out of calendar runway for Windows 10 October 2018 Update, really the only it withdrew from distribution earlier this year.

With not as much as 48 hours left inside the month, the lender is in danger of rendering obsolete discover fall feature upgrade and in many cases disrupting the scheduled support.

Although Microsoft officially released the refresh on Oct. 2, four days later it barred access to upgrade via Windows Update, told folks had installed it to remain seated off their PCs and warned users who had downloaded except installed it to trash the disk image. The real reason for the unprecedented moves: Quite a few users – Microsoft said 1/100th of 1% – reported your upgrade deleted all files in most folders, for example the important Documents and Photos directories.

The final word on 1809, Microsoft’s name included in the now-standard yymm labeling format, was three weeks ago, when John Cable, director of program management inside of the Windows servicing group, told customers that bugs had been fixed. But rather than again putting most people at risk, the lender handed the re-release about bat roosting who had volunteered to sample the OS by joining the Windows Insider preview program.

With your release of Windows 10 1809 now postponed by at least four weeks, the delay has impacted the upgrade’s support timeline.

Using definitive “Windows lifecycle fact sheet,” 1809 support for Windows 10 Home and Windows 10 Pro will expire April 14, 2020, too Windows 10 Enterprise and Windows 10 Education on April 13, 2021. (Microsoft recently extended support for Enterprise and Education from 18 to 30 months.)

If Microsoft restarted distribution of Windows 10 October 2018 Update today, it might shortchange customers on support. As opposed to the promised Eighteen months for Windows 10 Home and Windows 10 Pro, could possibly instead provide support for 17 months and 15 days. (Your initial Oct. 2 release date translated to 18 months and 12 era of support.) And Windows 10 Enterprise and Education would get something like the pledged 30 months.

“If Windows-as-a-Service might be a hosted service, if general availability is paused, may be the support window of 18 or 30 months extended by means of number of days for each and every pause?” asked Wes Miller, an analyst at Directions on Microsoft, durring an Oct. 11 tweet.

This is unclear if Microsoft will redress the support shortfall, and if so, how. In April, when Microsoft delayed the production of Windows 10 1803 within the month’s final day it added moments to support. Rrnstead of an Oct. 8, 2019 end of support for Home and Pro – founded upon an expected April 10, 2018, debut – Microsoft so that you can to expire Nov. 12, 2019. (That gave Home and Pro customers Eighteen months and 15 days of support.)

Microsoft could extend support for 1809 similarly. For example, should your firm re-starts distribution on Friday, Nov. 2, it would restate end-of-support for Home and Pro as May 12, 2020, giving users 18 months and Ten days of security patches and bug fixes.

When asked today whether Microsoft will prove to add more time to 1809’s support, a spokeswoman said the firm declined to comment.

Windows 10 users: Here’s all the ways the UI vary in the latest update

Leave a comment

Microsoft has added more elements of design to make Windows 10 advisable use for designers and developers, as per a recent report from MS Power User.

Microsoft released its design language Fluent Design in 2017 to exchange MDL2, with a new version of the Mail and Calendar apps. After that, the company has added new tools for Windows 10 developers to operate to design Universal Windows Platform (UWP) apps, including Z-depth and Shadow for 2D and 3D graphics, as our sister site Softwareonlinedeal reported.

Career offers, Microsoft has added more elements of design, including new controls towards XAML Controls Gallery-an app having to do with Microsoft to demonstrate the many controls available in the Fluent Design System and XAML, as documented in MS Power User. The app’s recent update includes new Motion controls, that supply a glimpse towards controls Microsoft are sure to add to Windows in the coming years.

The new Motion XAML controls include animation interoperability, which includes using a natural motion composition animation on top of a UIElement, ExpressionAnimation on an Ellipse element, and moving several related animations together using ExpressionAnimation, the report noted.

The update can also include connected animation features, which includes creating connected animations from your list page and also a detail page, or between elements on the same page. Finally, with new theme transitions, designers can utilize the EntranceThemeTransition when adding ideas to a page, utilization of PopupThemeTransition to animate frequent lowering and raising a popup, the report said.

These controls grow to be available in the XAML Controls Gallery app, and is available in the Microsoft Store, MS Power User noted. Microsoft also added the code below each control, so developers can without difficulty add their apps. Much better unclear if-or when-Microsoft will these controls to Windows 10, it’s likely that more Fluent Design elements will arrive from the upcoming 19H1 update to Windows 10, the report noted.
The main takeaways for tech leaders:

Microsoft has added more design elements to make Windows 10 better use for designers and developers.
The updates include new controls into the XAML Controls Gallery, that include animation interoperability and theme transitions.

Microsoft releases un-deployable Exchange Server 2019

Leave a comment

Requires unavailable Windows Server 2019

Microsoft has launched its Exchange Server 2019 communications, contacts and calendaring flagship best-in-class required Windows Server 2019 still being unavailable, leaving customers could not test and deploy the software.

Windows Server 2019 version 1809 was pulled from distribution latest research by along with the desktop Windows 10 equivalent, after users complained that a operating system releases deleted files during their computers.

“We’re aware all media for Windows Server 2019 and Windows Server, version 1809 has long been temporarily removed and Microsoft will give you an update when refreshed media exists.

Exchange Server 2019 rrs going to be fully best with version 1809, and also refreshed version,” Microsoft’s Exchange Team wrote inside blog post.

From yet, Microsoft hasnt provided a release date for that refreshed versions of Windows Server 2019 and Windows 10.

When customers can test it out, Exchange Server 2019 is considered to run better on multi-core systems with plenty of memory. Microsoft said the newest Exchange may use up to 48 processor cores and 256 gigabytes of RAM.

Exchange Server 2019 are also able to cache data on solid-state storage for fast access. It will likewise allocate more memory to active database copies when cacheing data, for improved performance.

Database failovers are faster in return Server 2019, using Bing-based search technology and overall, Microsoft promises that the new version from the communications platform is equipped for more users per server than before.

On the security side, Microsoft has cleansed old ciphers and hashing algorithms and Exchange Server 2019 will certainly use the Transport Layer Security 1.2 protocol along with, which might restrict support for legacy systems.

Microsoft also won’t improve Unified Messaging role offered on Exchange Server 2019.

This implies customers who currently connect third-party switchboard software or Skype for Business Server to modify can’t continue doing that with Exchange Server 2019.

Instead, Microsoft shows that customers move to Skype for Business Server 2019, use Cloud Voicemail, or migrate in the Office 365 equivalent.

Microsoft Releases 2019 Server Products for Exchange, SharePoint, Project and Skype for Business

Leave a comment

Microsoft on Monday announced the release of its 2019-branded application servers, including Exchange Server, SharePoint Server, Project Server and Skype for Business Server.

The fresh new servers are near the “general availability” release stage and is used in production environments. However, you will discover a catch for organizations looking to run them using the new Windows Server 2019 product. Microsoft released Windows Server 2019 on Oct. 2, but later held it back because of a file deletion issue that affected Windows 10 version 1809 users. Those client and server platforms are still on hold, but Microsoft is meaning to release an update, therefore plans to update the popular application servers accordingly.

“We will supply an update when refreshed media is readily available and will make sure that all Office 2019 services are fully works with the newly refreshed version,” explained Jared Spataro, Microsoft’s corporate vice president for Office and Windows marketing, in Microsoft’s announcement.

In addition, for organizations intending run Windows Server 2019 in their datacenters, they won’t buy the OS on certified hardware until around “mid-January 2019,” determined by Cosmos Darwin, a senior program manager on Microsoft’s Core OS team.

Exchange Server 2019
Exchange Server 2019 is readily available for download from Microsoft’s Volume Licensing Service Center.

One caveat is the Exchange Server 2019 comes with a dependency on Windows Server 2019, which restricts organizations wanting it right this moment. This dependency also represents a deal-breaker for organizations keeping with Windows Server 2016. The issue of Windows Server 2016 support is in all likelihood a surprising switch from Microsoft’s usual second-generation product support scenario.

Likewise, Microsoft is touting Exchange Server 2019 as replacements on the Core install option of Windows Server 2019. The latest messaging server works on the Desktop option of Windows Server 2019 also, but Spataro claimed which a Core option represents “the smart choice for our code” and therefore “Core provides the stablest platform for Exchange.”

Organizations may even get the Transport Layer Security (TLS) 1.2 protocol automatically with Exchange Server 2019, depending on an Exchange team post. Microsoft has plans installed to end support to your earlier versions (TLS 1.0 and 1.1) by the end of this month — not for the server products, additionally it is across Office 365 services. Upgrading the root OS is the typical treatment for the unsecure TLS 1.0 and 1.l protocols. One example is, Microsoft has previously indicated that Windows 8 or Windows Server 2012 or later OS versions use TLS 1.2 automagically. In addition to those efforts, browser makers earlier announced they will plan to end support for TLS 1.0 and 1.1 in 2020.

Many services back in July, Microsoft has pulled the Unified Messaging role from Exchange Server 2019. How little that role could be a potential problem for organizations that connected “either a third party PBX or Skype for Business Server to modify Server,” Microsoft indicated. Microsoft’s recommendation regarding organizations is always “consider migrating to Skype for Business Server 2019 as well as using Cloud Voicemail, or migrating to Office 365 with Cloud Voicemail.”

Exchange Server 2019 features include:

The capability to use “up to 48 processor cores and 256GB of RAM.”
Support for solid-state drives, enabling improved e-mail search.
A Dynamic Database Cache feature that has “more memory to active database copies.”
International e-mail (EAI/IDN) routing support.

SharePoint Server 2019
SharePoint Server 2019 obtainable at this Microsoft Download Center page. It’s not possible to upgrade with the release-to-manufacturing (RTM) version. SharePoint Server 2019 is supported on Windows Server 2019 (when available) and Windows Server 2016.

This new edition of Microsoft’s intranet server for collaboration and document sharing is certainly caused by bringing down support for so-called “modern features,” namely modern Sites, Pages, Lists, Libraries and Communication Sites, which they are all already offered for users of the SharePoint Online service.

The most crucial modern element missing from SharePoint Server 2019 is support for Hub Sites, the particular top-level organizing page in Microsoft’s modernized pages scheme. By modernized, Microsoft is speaking about a more simplified slot, plus responsive design for a mobile SharePoint app then it adapts well to varied screen sizes. On top of that, the availability for the new SharePoint Framework open source tooling for developers belongs to the modernized theme.

Features in SharePoint Server 2019 include:

The capability to upload files “up to 15GB.”
Increased URL path lengths, “from 260 Unicode code units to 400.”
Support on your # and % characters “in file and folder names across document libraries.”

Microsoft Project Server 2019 seemed to be released and its available by SharePoint Server 2019 download. Microsoft bundles the two main products, available on the market are licensed separately. Project Server 2019 will be the latest project management solution for replacements on an organization’s infrastructure and includes “performance, scalability, reporting, and accessibility or an expanded multitude resource engagement APIs,” per an announcement.

Skype for Business Server 2019
Microsoft’s latest unified communications server specifically in an organization’s datacenters readily available for download from a link at this particular page. At press time, though, the anchor text led to a generic page, so Skype for Business Server 2019 are probably not downloadable at this time. The new server is supported on Windows Server 2019 (when available) and Windows Server 2016.

Skype for Business Server 2019 will have the following features, as outlined by an announcement:

Cloud Voicemail support.
Cloud Call Data Connector support, and these can be used for monitoring call quality in hybrid environments.
Streamlined support for organizations moving to Microsoft Teams.
TLS 1.2 security support.

We will have coming support relating to the “Cloud Auto Attendant” and “Meetings First” features in Skype for Business Server 2019, Microsoft’s announcement promised. Cloud Auto Attendant “will be available later this year” therefore it may only be utilised in “hybrid” environments (on-premises servers plus cloud services) when also applying the Azure Active Directory service. Arrival in the Meetings First feature wasn’t described, but it surely allows organizations to play with Teams for online meetings.

Windows Server 2008 Migrations Is able to use Azure Site Recovery

Leave a comment

Enterprise users who are looking for migration alternatives for their Windows Server 2008 32-bit applications for the end of support procedures for the product in January 2020 can turn to Azure Site Recovery to conduct the migrations and extend support for any applications on Azure through 2023.

This new option, that led to announced by Sue Hartford, senior product marketing manager of Microsoft’s Windows Server division, on an Oct. 16 post concerning the Windows Server Blog, provides users with subs years of Extended Security Updates for free of charge in Azure if they ever migrate their old 32-bit applications from Windows Server 2008 or Server 2008 R2 to Azure virtual machines.

The Azure Site Recovery tool, which sometime back has allowed migrations involving 64-bit versions of Windows Server, has recently been updated to guide those 32-bit application

migrations, wrote Hartford.

“With eliminate support for Windows Server 2008 in January 2020 coming soon, now is a terrific time to begin modernizing your applications and infrastructure with the power of Azure,” she wrote. “The 2008 and 2008 R2 versions of Windows Server will reach End of Support on January 14, 2020. But customers who migrate these versions to Azure virtual machines will continue to get free security updates until January 2023. This buys customers a bit longer to upgrade or modernize, while setting out to gain partners . cloud.”

For enterprise users, this is always a welcome and helpful option that contributes flexibility on their long-term migration and infrastructure plans.

Classes . July, Microsoft offered similar Azure cloud migration techniques for customers who’ve been using SQL Server 2008 and 2008 R2, that is designed to reach the end of support on July 9, 2019. By offering those customers the selection to move their database applications at the Azure cloud, additionally will gain 36 months of free use on Azure without requiring any application code changes.

When Microsoft pulls the plug during a software product, it effectively means eliminate security updates, like for example the cases of Windows Server 2008 and SQL Server 2008, unless customers pay money for costly premium support. That options typically reserved for the biggest and wealthiest enterprise customers. Instead, generally speaking, customers will move to newer versions of applications, in particular SQL Server 2017.

The death of Windows Media Center as well as the five stages of HTPC grief

Leave a comment

Denial
Running Windows 8.1 so I can use Windows Media Center is actually fine, regardless if it’s 2018. Windows Media Center the correct way to watch TV on my terms. All Stick to do is purchase cable, there is nothing can record the entire shows I’d like with my HDHomeRun Prime. I don’t have to fool around with a single that streaming nonsense or multiple subscriptions to network-specific content. Basically if i wanted to, Possible even run the hack that lets me use Windows Media Center in Windows 10. Besides, all my saved recordings tend to be in .wtv format. It’s just fine.

Anger
Freaking Microsoft! I still can’t believe they dropped Windows Media Center after all this time. It’s all regulated the Xbox’s fault! To top it all off, all of the other options on the web suck. I don’t want to change the way do things or fight with someone else’s so-called “solution.” Plus, what else will function with a cable card? Making use of a cable card makes me super awesome and nerdy. I can not just give that up and be accepted as one of the normals.

Bargaining
Well, maybe We can cut cable only use Windows Media Center to record over-the-air TV. That’s still sticking it with the man, right? Residence stop paying for cable, I’ll save serious money each month, and can use that cash to buying new seasons associated with the handful of shows Website owners want to watch. The reality is, it’s probably better in this way because I do not need to watch commercials like I would if I streamed those shows from Hulu or something like that. It’ll be great for watch less TV.

Depression
This sucks. Any show is actually a choice between spending money or watching commercials. This became so much easier as i could pay just one bill and do all of it myself. My OTA channel selection is super limited, and some tips things are going, Survivor is perhaps going to be spoiled before Buy around to watching the fresh season. Everything am much better before.

Acceptance
This HDHomeRun DVR software actually has some nice features, and it’s really nice that the app runs on all our tablets and phones. I don’t even have the need for my Windows 8.1 PC a more?aall I was toting for was Windows Media Center. You’ll know, I could probably relieve gaming PC connected to the TV basically moved motion picture card into my home server. Having only one computer through the living room in preference to three is most likely the kind of thing which makes leaving Windows Media Center behind sting less. I bet that when I document your whole process and write it down for TR, will probably be exactly the kinda therapy I’d like to wrap this up and move on with life.

So it begins

Now, We are aware the thought process above must be similar to what no less some of you’ve got gone through. I figure I’m upon the tail end of converts from ye olde Windows Media Center, but I know there are actually diehards still around lamenting their loss or probably still fighting to possess Windows Media Center practicing Windows 10 from a post-April Update world. To the people of you good people, take a deep breath and pay attention to my tale. Maybe this assists you find peace.

I’ve used Windows Media Center since leaving BeyondTV sometime around 2008, right around the time the most important HDHomeRun came out. Around the period, I had my sights set on getting a Hauppauge HD PVR after I could. Before, my HTPC was built around a Core2 Duo E6600 using a passively cooled GeForce 8600 GTS. That hardware included a good run, it’s history and not part of the process today. Today’s story really commences with the details of an three different PCs that did everything and one PC that brought these individuals together.

The HTPC
First included late 2012, and running Windows 8 from the first day, my HTPC’s foundation was an AMD A10-5700 will be Radeon HD 7660D IGP. I am a bit captivated with APUs and mini-ITX just, but I won’t rehash old forums posts here. Produce mention, though, that your motherboard, an ASRock FM2A75M-ITX, became infamous for VRM fires soon after it was released. I never had a disadvantage in it, though, perhaps simply because of the 65-W TDP of my APU. I paired those parts with 8 GB of DDR3-1866 memory. A 128-GB Samsung 830 SSD plus a 2.5″ 750-GB spinner for recording storage rounded available system.

That setup got all assignments done for a little bit, but the IGP was arranged short for even the light TV gaming it actually was asked to do. In this way, I moved isn’t even close to into a new case, switched with a 3.5″ 2-TB hard drive, and dropped inside Asus Radeon R9 270 in the summertime of 2014. It hasn’t changed since?anot while it didn’t must, but given it was trapped by Windows Media Center and its dependence on Windows 8.1.

The home server
Built not long after the first incarnation using the HTPC above, my home server joined together in early 2013. Originally conceived as a good dedicated PC for storage and game servers, its hardware configuration has stood test of time. For around, I haven’t outgrown its modest storage devices, courtesy of three 2-TB Western Digital Reds in RAID 5. Other activities, the 16 GB of DDR3-1600 memory, picked for RAM drive experimentation, in order to be a respectable capacity even by today’s standards. The Intel i5-3450S sitting during the system’s heart is a bit of an odd duck, but it surely can turbo up to a whopping 3.5 GHz and does its job within 65 W. Everything resides on a Fractal Design Node 304 case, that i still have a substantial attachment to.

The gaming PC
If i replaced my main rig funding early 2017, my old system became suitable for redeployment. The venerable Intel i7-2600K that lived inside needs no introduction, but the system did require a new video card. My GeForce GTX 980 Ti had jumped ship to my Kaby Lake build, not surprisingly ,. Before the mining craze hit, I obtained an MSI Radeon RX 470 for only a scant $175 to consider its place. My old PC still rocked 16 GB of RAM and a 500-GB SSD, besides.

At the time, hooking this PC as many as my TV solved various problems. It was subsequently vastly superior at gaming in contrast to HTPC I had before, which could actually play 4K YouTube videos without giving the impression of a fool (plus the fact its ability to perform chop-free playback of 1080p video in funky broadcaster-specific players). As being a Windows 10 box, though, it couldn’t run Windows Media Center.

Microsoft announces Office 2019 at its Ignite conference

Leave a comment

Trapped on tape, Microsoft announced some changes towards requirements for Office. Existing Office perpetual products will no longer be able to get connected to Office 365 services, starting in 2020. But while Office 2016 might not exactly work properly anymore, there’s another perpetual Office product in the process in Office 2019.

The brand didn’t go deep into any specifics regarding what extra features and improvements that we’ll see from your product, when it did state that Office 2019 will be freely available in fall 2018, accompanied by a preview there for Insiders in the year.

Some might find it a bit surprising that Microsoft offers a new Office product whatever. Many have speculated that a future will be Office 365 and so the company would eventually drop 2012 off of the name. But no, apparently , there will be one more perpetual Office license version that you can buy.

In fact, with updates coming through Office 365 getting service, it’s unclear how this might affect extra features that are constantly being distributed around existing products. Luckily, we’ll learn more about Office 2019 soon, conscious will likely be an occasion at some point to instruct it off.

A totally new version of Office isn’t an small deal, and also now we wouldn’t expect them to unveil the total product behind closed doors in a session at Ignite.

Update: Microsoft has published a short blog post, teasing several new features:

Office 2019 will add new user so it capabilities for purchasers who aren’t yet ready relating to the cloud. Here is an example, new and improved inking features-like pressure sensitivity, tilt effects, and ink replay-will will let you work more naturally. New formulas and charts can really make data analysis for Excel more potent. Visual animation features-like Morph and Zoom-will add polish to PowerPoint presentations. Server enhancements will incorporate updates on it manageability, usability, voice, and security.

SQL Server on Linux – External Memory Pressure with 2019 CTP2

Leave a comment

In this blog post we’re preparing to revisit how SQL Server on Linux responds to external memory pressure. They can be a very long post, plus it ends by himself not knowing exactly what’s going on…but your journey is pretty fun…let’s go!

On Windows-based SQL Server systems we’ve become accustomed to the OS signaling to SQL Server that there’s a memory shortage. When signaled, SQL Server will kindly start shrinking it’s memory caches, just like buffer pool, to have overall system stability and usability. Well that story turns out to be different in SQL Server on Linux…last year I wrote a very similar post for SQL Server 2017 RTM and also the way it reacted to external memory pressure, ensure that out here! This led to quite a dramatic story, you can easlily literally cause SQL Truly swap nearly its entire process address space out over disk! Now, let’s look and enjoy how SQL Server on Linux responds to external memory pressure in SQL Server 2019 CTP2.
The Scenario

Our SQL Server on Red hat is a CentOS 7.5 VM, running SQL Server 2019 (CTP2). There is 12GB of physical memory and 80% in the is dedicated to SQL Server via mssql-conf about 9.2GB, the default configuration. I’ve also set Max Server memory to 8GB for ones SQL Server instance.

So let’s start off SQL Server on Linux 2019 CTP2 and query the SQL Server’s cache sizes when there’s no data loaded. I’m gonna look in sys.dm_os_memory_clerks for memory allocation accounting information. In Figures 1 you can easliy get a sense of the memory distribution over the system’s caches. Special shoutout on the new “Azure Data Studio” I’m using through these demos.

Now, I’m preparing to load an 8GB table inside the buffer pool, maxing out SQL Server’s MAX memory instance setting. Now we’ll check out the allocations again. In Figure 2, capable to see the buffer pool is going to be dominant consumer of memory and the our database is definitely the dominant consumer inside the buffer pool. Happen to be so good, eh?

Getting Memory Information From Linux

We will use tools like ps, top and htop to appear fashionable our are virtual and physical memory allocations. Capable to also try looking in the /proc virtual file system for your process and check out the status file. In here we’ll chose the point in time status with regards to a process, have the ability to the types of memory allocations for just a process. We’ll get granular data with the virtual memory allocations in addition to resident set scale the process. There are the interesting values inside the status file we’re heading to focus on today.

VmSize – total current virtual address space of an process
VmRSS – amount of physical memory currently invested on the process
VmSwap – total amount of virtual memory currently paged appear to the swap file (disk)

We use the command pidof sqlservr to determine the process ID to our SQL on Linux process, within our case it’s 14689. When running SQL Server on Linux interest in two processes for sqlservr, we’re going to look the particular with the higher process ID for the one using the lower PID is a watchdog process.

How to access the status information to our process we look in /proc/14689/status

Below certainly is the output from process’ status file, filtering for a values we’re inquisitive about. You can see about 16.4GB of Virtual Memory (VmSize), 7.9GB ones is in actual RAM (VmRSS) and 0MB from the swap file (VmSwap). Wait an instant, 16GB of for VmSize? Yea, 16GB for VmSize. That’s the reserved allocation for the complete process. More that on a second…

VmSize: 17165472 kB

VmRSS: 8579016 kB

VmSwap: 0 kB

Now, after we look back at a previous post here on SQL Server 2017 RTM, the memory distribution will be a bit different. You could see about 10.16GB of memory in VmSize

VmSize: 10661380 kB

VmRSS: 8201240 kB

VmSwap: 0 kB

Phantom Memory Allocation?
Now, I hardly ever post something while i don’t have an answer to get a specific behavior even so case I don’t. My head on this are, that 16GB might be the reserved allocation for the whole process. Linux relies on a demand paging allocation system therefore majority of the process access space is just a reservation and isn’t backed by actual pages. So it’s not *really* consuming physical memory. But things i do see as relevant is the process appears to be carry that allocation forward, since loaded memory in, the VmSize went from 8GB (the VmSize when SQL Server Starts) to 16GB (next time i loaded the 8GB table). I’ve reported this into your product team that i’m awaiting to an answer within the ~8GB discrepancy between the two tests.

Let’s Then add activity Pressure

By having a small C program I wrote, I use calloc to allocate large parts of contiguous memory thereafter I have the system continually write data within the memory buffer to ensure that those pages holiday in physical memory. Utilizing this program, let’s allocate 7GB of RAM. I’m choosing this value because its travelling to cause my system to exceed it’s physical memory however exceed the amount of money virtual memory with my system when for instance the swap file’s size which could be 5.8GB tiny system. Things will receive really dicey in case you exceed physical and virtual memory size, processes will quickly get killed. Microsoft documents an instance here. So you know how important adding a monitor for external memory pressure is, photographs allocated 7.5GB and exceeded physical + virtual memory Linux killed their memory allocation program and SQL Server to cover the stability among the system, oomkiller is one area to look out for!

Now, let’s check out the memory accounting information at /proc/PID/status in my memory allocator program. Within a output below you can understand we have near enough 7GB of virtual memory (VmSize) allocated and nearly an identical amount of memory that’s resident in physical memory (VmRSS) and without any data for the swap file.

VmSize: 7344248 kB

VmRSS: 7340312 kB

VmSwap: 0 kB

Now in SQL Server 2017 to be able 7GB program running would cause Linux to need to make room in physical memory of this process. Linux performs this by swapping least recently used pages from memory in the market to disk. So under external memory pressure, let’s check the SQL Server process’ memory allocations per Linux. In the output reduce see we still a VmSize of around 10GB, but our VmRSS value has decreased dramatically. In reality, our VmRSS will now be only 2.95GB. VmSwap has risen to 5.44GB. Wow, that’s an obvious portion of the SQL Server process swapped to disk.

VmSize: 10700328 kB

VmRSS: 3098456 kB

RssAnon: 3096308 kB

VmData: 10442840 kB

VmSwap: 5711856 kB

In SQL Server 2019, there’s a distinct outcome! While in the data in this article see our 16GB VmSize which won’t change much with thanks to the virtual address space for the process. Bring back large external process running SQL Server reduced VmRSS from 7.9GB (from Table 1) to 2.8GB only placing about 4.68GB inside the swap file. That doesn’t sound considerably better, does it? I thought SQL Server was going to subside with the external memory pressure…let’s keep digging and enquire of SQL Server what it mentions this.

VmSize: 17159552 kB

VmRSS: 2938684 kB

VmData: 16806460 kB

VmSwap: 4911120 kB

What’s SQL Server Consider?

In SQL Server on Linux 2017, we got a large slice of the process address space swap out and also saw those pages stay resident in SQL Server’s buffer pool or really any section of the SQL Server process address space mainly because the Linux kernel is really an equal opportunity swapper…so anything contained in the caches managed by SQL Server didn’t know if that memory was resident in physical memory or was on disk. In figure 3, we see the top memory consumers after external memory pressure, our buffer pool in order to be fully populated with his table data.

Ok, let’s examine what happens in SQL Server 2019 with external memory pressure. Looking at the memory distribution, advertisements for classic that the memory clerk for SQL Server’s buffer pool reduced its memory footprint from 7,227MB (the worthiness from back in Figure 2) right after the buffer pool was basically loaded with our large table. Wh then applied external memory pressure along with 7GB process and we also see the buffer pool is reduced to 3,502MB a reduction of 3,725MB. Cool, seems to resemble we dumped our buffer pool to lessen the system nevertheless, not the whole buffer pool, there’s still 3,502MB in memory. Yet the SQL Server 2019 on Linux process still swapped out about that much data (Table 5)…what’s materializing? I still don’t know. Let’s keep digging.

Now, in SQL Server 2017 on Linux Resource Monitor didn’t exist…let’s investigate what we have in SQL Server 2019…using the query from Amit Banerjee and Sudarshan Narasimhan in the following paragraphs here let’s see what actually happened according to the newly implemented Resource Monitor for SQL Server 2019 on Linux.

Inside the output of this query, we can observed that System Indicator is 2 at times of external memory pressure. This is truly a signal from Resource Monitor to SQL Server to dump its caches to reduce the health of all around system. We certainly observed that for the output in Figure 4. But everything we also found reality Linux is placing 4.68GB of memory within the swap file thinking that SQL Server is holding 3,502MB of memory within a buffer pool whilst VmRSS of the process is 2.8GB (Table 5). To ensure the question remains, exactly why is SQL Server swapping a great deal of its memory inside the market disk and holding on to so much memory with the buffer pool even if it’s seeing the more reduced memory signal from Resource Monitor. This records are further saved by the fact that just about every day SQL_CommitedMemory_KB staying relatively stable around the light on the external memory pressure, the expectation is the fact would reduce. So it’s like it’s not nearly finishing your responsibilities deallocating the memory. So let’s ask Linux how much it thinks about this.
Resource Monitor on Linux – Earn money think it works…
If you’ve check this out blog before you know I like to use strace to recognise how applications talk with the OS via system calls. Well, let’s use that method to try to evaluate what happens when SQL Server starts dumping it’s cache under external memory pressure.

Over the last section, we learned that Resource Monitor can track everywhere memory conditions in Linux. Inside of this section, let’s discover how it interacts with your Linux memory management system to deallocate memory.

From the output below (Table 6) can be seen the aggregated system calls when I’m applying external memory pressure to SQL Server on Linux. From that output, it feels like SQL Server on Linux uses memory mapped files, that is a file access technique where files are opened mapped straight into a process’ memory address space. The can then access the file via direct memory addressing as compared with using system calls. This style of access actually makes very well to the internal file structures used for SQL Server data files.

During external memory pressure, the madvise one among the frequently called system call do your best. This system call is utilized by applications to advise (hint) the kernel on the things to do with ranges of memory under certain conditions. Over the last section, we observed that Resource Monitor can sense the external memory pressure and signals SQL Server to pay off its caches which is likely the implementation of methods those caches are dumped.

Under memory pressure, the madvise system call referred to as with the MADV_DONTNEED flag for giant address ranges in SQL Server’s process address space, the memory mapped file. The MADV_DONTNEED flag tells the kernel the application just isn’t going to expect to access these pages in the foreseeable future and they could possibly be discarded consequently freed rrnstead of swapped out to disk. Look at the kernel source code in charge of how it works.

madvise(0x69274a000, 8192, MADV_DONTNEED) = 0

My theory is actually is how Resource Monitor is signaling to your OS which these pages should needed and can be deallocated due to the semantics of the madvise system call all pages are marked as redundant. So we look at reduction in the size reported by SQL Server’s memory clerks. But some tips i find interesting is most likely the amount of memory that’s still hitting swap whenever we look at the memory accounting information to the individual processes along with IO profile of one’s system during external memory pressure. The program seems like the kernel and the application is holding onto pages and they’re hitting swap rather then being deallocated.

When i decided to my theory and I’m wanting to bring the pieces together in our emerging technology since it’s still in CTP. So in case you have some insight relating to what’s happening at this particular layer, I’d enjoy hear from you 🙂

Top five SCVMM 2016 features to look out for

Leave a comment

Microsoft has added new SCVMM 2016 features and enhanced existing ones, including management features for compute, security, storage and networking.

Before familiarizing yourself utilizing the top SCVMM 2016 features, take note that the installation process doesn’t provide an opt-in and opt-out alternative for the complex event processing (CEP) program. That’s most definitely because Microsoft wishes to collect CEP details for SCVMM improvement purposes.

Resolved feature gap between SCVMM and Hyper-V

In the last release of SCVMM, individuals lag when managing all of the features of Hyper-V. For example, SCVMM lacked management support for a lot of of the new Hyper-V features.

SCVMM 2016 now supports managing the vast majority of Hyper-V 2016 features. Here is an example, SCVMM 2016 fully sports Cluster Rolling Upgrade feature. This includes moving VMs running within a Hyper-V 2016 cluster towards node in the cluster, evicting the node, installing Windows Server 2016 located on the node and then joining it into the Hyper-V cluster.

Centralized Storage QoS policy-driven wizard

Just like Cluster Rolling Upgrade feature, you can actually apply the policies in your centralized storage service quality (QoS) engine developing a wizard which are available from SCVMM 2016. To configure storage QoS policies on Windows Server 2016 Hyper-V, it’s best to use PowerShell.

SCVMM 2016 features also have the ability to assign policies for existing and new VMs.

Manage Nano Server via SCVMM 2016

When using the release of Windows Server 2016, in a position includes Nano Server, Microsoft added allowing you to manage Nano Server in SCVMM 2016. You can provision both virtualization hosts and VMs by running Nano Server. You might also use Nano Server cmdlets to put together images for Nano Server deployments. Use a Import-Module NanoServerImageGenerator.psm1 command to import Nano Server cmdlets.

Networking and security enhancements

You will find use SCVMM 2016 to provide an SCVMM template that also includes the configuration for deploying multi-node Network Controller, Windows Server Gateway and Software Load Balancer components.

SCVMM 2016 gives the ability to add or remove an electronic network adapter from the production VM. Similarly, it’s easy to add or remove static and dynamic memory for VMs. For instance, you can run the PowerShell commands below so as to add a virtual network adapter up to a running VM:

$ThisVM = Get-SCVirtualMachine -Name “TestVM”
New-SCVirtualNetworkAdapter -VM $ThisVM -Synthetic

To eradicate the virtual network adapter since the VM is running, execute this PowerShell command:

$ThisVM = Get-SCVirtualMachine -Name “TestVM”
$ThisAdapter = Get-SCVirtualNetworkAdapter -VM $ThisVM
Remove-SCVirtualNetworkAdapter -VirtualNetworkAdapter $ThisAdapter

The latest SCVMM 2016 features enable the deployment of Shielded VMs to authorized hosts. You may deploy new VMs to authorized hosts in case you create those VMs.

Storage Replica and SCVMM 2016

You should utilize the Storage Replica feature to copy Hyper-V cluster files using synchronous replication, which helps data mirroring between physical sites with crash-consistent volumes for recovery purposes. Which can be used SCVMM 2016 to configure two data endpoints to copy each other.

You may even deploy primary and secondary volumes within a single Hyper-V cluster or between two different Hyper-V clusters or two stand-alone Hyper-V clusters. Storage Replica with SCVMM 2016 reduces shed network costs helping you avoid complex configurations.

Along with the SCVMM 2016 features stated earlier, Microsoft will continue to back up Citrix XenServer, but it removed support for VMware vCenter 4.1 and 5.1.
