SQL 2012 :: High Memory Utilization For Reporting Services In AlwaysOn Mode?
Mar 26, 2015
We have two server configured in always on mode .
windows is sql server 2012 64 bit edition and sql server is 2012 64 bit edition.
RAM installed on both server is around 65 gb of which 49 gb is max server memory allocated for sql services on both servers.
database related to reporting services are also in always on group .
We have also configured for reporting services and both are running on their respecting server.
Issue is on primary server reporting service is using almost 7 gb while on secondary it is using 10 gb even when there are 5 reports and its used within offices .
what issue and how to check why ssrs is using high memory..
any query , perfmon counters
reports are randomly used at client side
i have checked memory utilization through task manger..
We have a system(32GB RAM and 2 TB hard disk, Windows7,SQL SERVER 2008R2 enterprise 64 bit). Looks like whenever i run some query(even query result 50 records) on the database, the Memory utilization is very high(30 GB) in task manager. How can i control this over usage? The memory setting is default in server properties(min 0 and max 2147483647).
I know I should probably be posting this in the RS section but I have a Win 2008 R2 server and RS 2012 along with SSIS and Database server installed. I also have SQL 2005 instance with Sql 2005 SSIS running on the server.
I saw that Reporting services was consuming 9gb of ram a few days ago with no published reports. It's just a default install.
So I investigated the settings and the document: [URL]......
I added this section to the reportserver.config file to restrict memory usage
I have a few in house developed application (VB based) that access the SQL server for adding, appending , creating tables. The application does the changes thru queries dynamically generated at the application level.
My MS SQL Server runs on a PIII / 256 MB Ram / 18 GB HDD
The problem is that the memory utilization of SQL server keeps growing constantly. Out of 512 MB (256 Physical + 256 Virtual) available teh memory utilization reaches a level of 490 MB and statys constant. Though SQL Server shows a utilization of 150 MB.
I suspect that SQL is not releasing memory back to the system. Please help in resolving. The problem may lie at the applications developed.
I am using SQL Server 2012 and my AlwaysOn High Availability features is not enabled? What should I do. Is this requires any extra system requirements to be installed?
I came across an issue while migrating from SQL 2005 to SQL 2012 and using AlwaysOn Group. For some strange reason, when ever i connect to the Listener name for each AlwaysOn group, it list all the databases which is on the SQL instance, so i would be able to see databases that is not part of that Availability Group. I am not using default port, so have to put the port after the Name to connect and both Instance and Listener are using different port. Testing the fail over works fine too, when i perform a manual failover, i can connect to any of the databases in the group from my application with no problem.
Considering that the Listener Port is different to the port which the instance is using?
Secondary replica database(setup in async mode) of AlwaysON went in "restricted mode" during weekly reindex operation.
So I have tried below steps
1) Executed following statement on the same secondary replica database where the issue exists
alter database <DBNAME> set multi_user with rollback immediate
but it failed with the error saying "The operation cannot be performed on database "dbname" because it is involved in a database mirroring session or an availability group. Some operations are not allowed on a database that is participating in a database mirroring session or in an availability group. ALTER DATABASE statement failed."
2) Primary database is multi_user but still tried following command on primary replia database(thinking it will replicate)
alter database <DBNAME> set multi_user
but no luck. The secondary alwaysON database shows (synchronizing) as the alwaysON is set in async mode but the command doesn't replicate across secondary
so we are left with the only option to re-setup alwaysON but I want to avoid it as database size is huge..
issue where SSRS reports being executed from a report library in SharePoint intermittently are reloaded after hitting the apply button to run. Â We are using SSRS 2010 and SharePoint 2013 in integrated mode. So a user clicks on the report, fills in the parameters and hits apply. Maybe 70% of the time the report runs fine. Â The other 30% the report just reloads and wipes out any parameter selections. We do have a load balancer in front of the web servers.
I've ran fiddler to capture some of the error logging.
Things we have tried. Multiple versions of IE 8,9,10,11, Firefox, Chrome. Â All browsers seem to exhibit the behavior.
We ran so more traffic monitoring and it doesn't appear on these refreshes that report actually connects to the data context so it seems to be failing prior to that. (Possibly at the SharePoint server. Logging from the server apparently didn't show much in terms of when this occurred) It doesn't seem to matter if the report has 1 or 10 parameters.Â
We did notice that when we took the load balancer out of the equation and just hit the web server directly, the refreshes "appeared" to decrease in regularity but still occur.Also, the reports do not exhibit the refresh issue when running locally within Visual Studio 2013.
I have been having issues with our SQL server for awhile now. It seems to run out of memory every few days and when I look at the memory dump, the MEMORYCLERK_SQLOPTIMIZER seem to take over memory and eventually cause the server to crash.
Here is the SQL verison we are using: Microsoft SQL Server 2012 (SP1) - 11.0.3460.0 (X64) Jul 22 2014 15:22:00 Copyright (c) Microsoft Corporation Enterprise Edition (64-bit) on Windows NT 6.2 (Build 9200: ) (Hypervisor)..It is on a VM on Windows 2012 server. It has 20gb of RAM allocated to it and the MAX Server Memory is set to 16.5gb.
I have seen the MEMORYCLERK_SQLOPTIMIZER grow to about 11gb at the time of the server crash. Why that is happening? What is causing the memoryclerk_sqloptimizer to get so high? I have looked it up and it looks like it has to do with ad hoc requests, but is there something I can do to bring that memory down when it gets so high so that I can prevent a server crash?Do we just need to add more memory or is there a memory leak somewhere?
After a fresh install of SQL 6.5 with SP5a(or without), the cpu is running at anywhere from 50%-80%. It is loaded on a PDC, but when I stop the sql service cpu utilization drops to 0-2%. When I start the sql service it's right back up there, does anyone have a suggestion as to how to fix this or why the service would be doing this?
I am getting high CPU utilization on the SQL Server process (>90%). However the overall utilization (NT -- entire box) always seems to be under 50%.
Can someone explain why this is happening. The server is a quad; the SQL server process seems to be using only two CPUs at a time (not the same ones all the time).
Lightweitht pooling has been turned on and the maximum worker thread size has been left at the default value (255).
How can I configure SQL options to spread the load across all four CPUs ??????
Could anyone help me in finding out why the cpu utilization is very high??
I have two servers say, Server A , server B. There is a transactional replication going on from server A to B
There is a table say Table A on server A, which is being replicated to server B.
I created a trigger insert and update trigger on Table A on server B (i.e. on subscriber). Since then, the CPU utilization for server B is very high 80-90%
when i used profiler, i could see .whenever replication stored proc for insert or update executes..cpu utilization goes up..
trigger just insert the updated/inserted rows into some other table.
Could anyone tell me why the cpu utilization has gone up so much?? i am using sql server 2005
Our company recently combined our DBs into one SQL 2005 Server.
Dell Power Edge 1800 with 3.00 GHz Xeon Processor 800 FSB, 1 GB of RAM Dell Power Edge 1600 with 2.80 GHz Xeon Processor 533 FSB, 1 GB of RAM
Combined into one: Dell Power Edge 2950 Dual Core 1.6 GHz Xeon Woodcrest Processor, 4 GB of RAM
However, the CPU utilization on this new server is maintaining at about 90% with 3.82 GB of RAM used as well. It's a Windows Server 2003 R2 x64 edition running SQL Server 2005 SP2 x64. I have searched around Microsoft's website for any information that could be of help to me, but I was unable to locate anything. I was hoping that someone could provide some insight as to why this might be occuring. Or if this is a known issue.
We are using an IBM Xeon server with 4 GB RAM with windows 2000 server and MS Sql server 2005.
More frequently our server responce time is very slow, although the cpu utilization is between 7 - 10 %. we can not able to run even notepad on the server. we observed that the memory occupaid by the sqlserver prog is high. If we restart the server then it will return to normal level. But we do not want restart the server frequently.
In SQL 2005 Replication Monitor i was not seeing details for any of the publications on the "Distributor to Subscriber Histroy Tab" so i decided to stop and start synchronisation on this one publication. At this time there were approximayely 20000 undistributed commands. After the stop/start of the distribution agent, i started seeing messages like "x trasactions with x commands were delivered". Then i went and restarted all the other distribution agents using the Replication Monitor.
Has anyone experienced this kind of a behaviour?
The second issue is that our trasnactional replication looked to have caught up but i was supprised find that the distribution server was running at 100%. A profiler trace of the distribution database revealed that sp_MSget_repl_commands procedure was being executed and costing approximately in excess of 400 000 reads, 7000 in CPU cost and 15sec in duration. To me it looked as if sp_MSget_repl_commands has chosen an inefficient execution plan but then realised i couldn't recompile system procedures. I think a stop and start of the SQL instance is the only option i have.
We are using an IBM Xeon server with Sevrer 2000 and sql server 2005 with 4B RAM.
We noticed that the responce time of the server is very slow. During this time the memory occupancy by the sqlserver is very high. Althouh the cpu utilization is very low (7-10%) we are unable to run even notepad on the server. In some other situations the cpu utilization will be 100% (for more than one hour) during this time also the sql server occupaies more memory. If we reatarts the server then the problem will be fixed, but we do not want to restart the server very frequently.
We are having a big performance issue at our site. Here is the configuration of the box running SQL Server 2005:
64 bit Windows Enterprise Edition + SP1
Dual CPU, 16GB RAM
RAID 1 and RAID 5 - internal
SQL Server 2005 64-bit Enterprise Edition
With SP2 (CTP from December)
The "Lock Pages in Memory" is set and is being run under the same account that is being used to run SQL Server Services.
We are noticing that under load, the CPU utilization becomes nearly 100%. I have researched this and have come across a couple of posts that indicate that this issue was fixed in SP2 - example: One post talked about the hotfix #716 which is also a part of SP2 but even after the application of that service pack, we are still having this issue. I haven't tried setting the parameterization option to forced for the database yet.
Is this a known issue with SP2? If not, what can we look for and fix in our environment? Please let me know if I can provide more information.
I have a question for anyone who mas some tips/pointers for optimizing SQL merge replication publications.
The front end web server is running IIS 6.0 on Windows 2003 x86 Server Standard (Server A). The back end database server is running SQL 2000 Standard on Windows 2003 x86 Standard (Server B). The merge replication clients connect via HTTPS over the Internet from a custom C#.NET 2005 application using SQL 2005 Mobile running on Windows Mobile 5.0 (Client).
The publication itself has several filters on it. The entry point uses the user's Windows username to start the filter. Based on the user, it then filters the records in multiple tables. There are 68 articles and 44 filter statements. The filters extend multiple layers deep, in other words they are not all filtering off the HOST_NAME() variable, some tables filter from records in tables that filter from the HOST_NAME() variable. The publication is set to minimize data sent to the clients, and considers a subscription out of date if it has not synced in the last 4 days. All the rowguids are indexed as well.
There are approximately 35 clients actively using the application at any given time. On average, a client will initiate a merge replication 3-4 times per hour from 8am-5pm. Generally, a sync will take between 10 seconds and 2 minutes to complete, with most of them being around 30 seconds on average.
When a client starts a sync, there is a spike to about 50% on the server's CPU graph. If multiple clients attempt to sync at the same time the CPU utilization can be pushed to 100% for extended periods (more than 30 seconds).
I recently completed a project to increase the bandwidth available to the clients, and plan to reduce the number of filters significantly (although this will obviously increase the amount of data going to the clients and the storage needs on the individual devices). I also plan on changing the setting to not minimize the amount of data sent to the clients.
Having said all that, does anyone have any information about how to further optimize merge publications to mobile clients? The next publication will be on SQL 2005 x64 Standard if I can solve the issues in the text environment. I would like to enhance the publication as much as possible to make the end user experience better than it currently is.
Hello, we have a customer-facing ASP.NET web reporting application that allows the user to a). select a report b). make report settings (filter, sort, include/exclude columns), and c). run the report. An Oracle stored proc is used to return the data into a DataSet. Today the output is displayed in a bound, paginated DataGrid.
We€™d like to €˜plug-in€™ Reporting Services for improved formatting, grouping, matrix reporting, drilldown, graphics, etc.. I have read through the online docs, examples, and tutorials but have not found the exact (high-level) information I€™m looking for.
We need to keep our report settings page, Oracle SP architecture, etc... Is there a way to simply hand off a dynamically created DataSet to a report for display €“ like binding to the DataGrid? The data (query) would be specific to a report but columns can be selected/unselected for display. In terms of deployment, is it necessary to install SQL Server in each environment (DEV-Integration, QA, PROD) to support Reporting Services? Since we are essentially an Oracle shop, this could be a tough sell. Is it possible to develop the report on a dev workstation (perhaps with SQL Server), and then publish to a web server where SQL Server is not installed?
These are obviously high-level questions - any help will be appreciated (examples, how-to's, etc..) €“ thanks in advance. -Bill

I installed 4GB of memory and I have never seen SQL memory utilization go beyond 2GB. I have SQL server set up to use as much memory as it needs. Does anyone no if SQL server can make use of more than 2GB.
Ours is a SQL 7.0 Enterprise edition with NT 4.0 Enterprise Edition. SQL Server has been configured with the default, 'Dynamic memory Allocation'. The system has 4GB of RAM. This is a dedicated SQL Server machine. But SQL Server seems to use only 1.8GB RAM(Counter: Total Server Memory) The page faults seem to be a max. of 600 and an avg. of 100. The processor utilization has suddenly increased to 90%. Is there anything wrong with the way SQL server is using memory? Is is not true that SQL Server 7.0 Enterprise edition can use upto 3GB RAM in a 4GB system?
Are there any links that can help troubleshoot this problem?
What do people think is normal for memory utilization? I know that's toobroad, so here are some basics.MS SQL Server 2000, Windows 2000 Server, 2GB RAMDb 1, size = 2.0 GBDb 2, size = 300MBDb 3, size = 50MBDb 4, size = 30MBDb 5, size = 30MBTypically 4-6 users, moderate usage 8-hrs/day. Performance has not slowed.Reboot on Sunday. sqlservr.exe in the Task Manager reports the followingSun 61MBMon 200MBTues 800MBWed 1,124MBThu 1,424MBFri 1,303MBI was getting srv 2020 errors when I had just 1 GB RAM: "The server wasunable to allocate from the system paged pool because the pool was empty."Then I did several updates to address this and got more RAM. I haven't seenthe errors since, but I haven't waited for them to happen: I'm rebootingevery week now. The memory numbers make me suspect SQL Server.Scratching my head. Not sure if my problem is gone, and this is normal SQLServer 2000 behavior, or if my problem is still lurking and I've only mutedit a bit.Any thoughts greatly appreciated.Tom
My server has 16GB RM but it is using only 3GB. And I see my server is using 3GB of Virtual Memory, too. Why my physical memory is not being utilized? How can I increase Physical Memory usage and decrease VM usage?
We have SCCM 2012Â primary site and Remote SQL 2012 server. Due to hardening and password reset we are facing reporting issue.
while we Open the SRS report in SQL server and try to edit the Report (Report Builder) we are getting following error due to which we are unable to configure Reporting Service point in the SCCM 2012 server. We created the New Reporting server database still we are getting the below error.
Can someone point me to some good articles or perhaps directly supply some words of wisdom with regard to wise utilization of variables within a T-SQL script from and standpoint of conserving memory usage and improved execution cost?
For example:
(1) Is it better to use varchars, nvarchars, etc. defined with minimal lengths to support the needs of the script or is it just as efficient to declare all with a length of say 4,000?
(2) I've seen behavior that leads me to believe that when passing a variable as a parameter in a nested procedure call, if the declared types of the parameter and the variable being passed in don't match (i.e. one is numeric(38,10) and the other is int), then implicit type conversions hurt performance. Is this true and how broadly does it apply?
(3) Does the number of variables declared in a script materially impact the performance and / or resource utlization?
(4) Is it more efficient to have a series of variable value assignments in a single SELECT statement versus a series of SET statements? Should I always perfer one to the other? Only within a looping construct?
Hi everybody! I've created a report in reporting services and in it i need to have a dynamic textbox. Let me describe more.I have two reports ,in first report i have manegers' names .After that users see first report and manegers' informations for example their names and saleries , they want to select manegers on base of for example their saleries ,i mean she/he must see informations then decide and select manegers who their employees will be shown in second report ,in this case i need a textbox that the user can write Yes or No in it,and i need multiple select. After that users select their manegers they can see manegers' employees in second report. I need a textbox that has two values (Yes and No) and these values must be shown in textbox in preview mode to select by users or user can select Yes or No . Can anybody help me? ShimaS
Dear friends, I'm having problems changing the reporting services from native modo to integrate mode... I saw a lot of articles and tips, but I still have problems... For example, when I change my database setup to integrate mode there is all ok, but in the SharePoint tab has an image with error...
and in the sharepoint server when I need to grant acess to database gets an error to...
and the page that always runned : http://CGDWX01115883/ReportServer
after I change to integrate does not work and gives me this error: Reporting Services Error
An internal error occurred on the report server. See the error log for more details. (rsInternalError) Get Online Help

I'm having problems setting up Reporting Services in SharePoint Integration mode. The development environment works fine, but I can't get it to work in production.
Problem seems to be in the authentication between SharePoint and Reporting Services. When I go to "Set Server Defaults" in the SharePoint central administration I get the following message:
Code Snippet
An unexpected error occurred while connecting to the report server. Verify that the report server is available and configured for SharePoint integrated mode. --> System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.Net.WebException: The request failed with HTTP status 401: Unauthorized. at System.Web.Services.Protocols.SoapHttpClientProtocol.ReadResponse(SoapClientMessage message, WebResponse response, Stream responseStream, Boolean asyncCall) at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters) at Microsoft.SqlServer.ReportingServices2006.ReportingService2006.ListSecureMethods() at Microsoft.ReportingServices.SharePoint.Soap.ReportService2006.ListSecureMethods() --- End of inner exception stack trace ---
I get the same message when trying to deploy a report from Visual Studio to a SharePoint lib.
Some info:
- SP apppool is running under domain account a
- SSRS apppool is running under domain account b
- SP uses NTLM authentication
- SP and SSRS are running on different servers
- SSRS Configuration shows all green checkmarks
Things I tried:
- Basic authentication instead of Windows Integrated on SSRS
- NTLM only instead of Negotiate on SSRS
- Settings SPN's for SSRS, didn't help
- Checked NTFS rights on ReportingServer dir, were fine (Domain users have read/list)
Does anyone have an idea about how to solve this? Any help is appreciated.
We have started to use reporting services in integrated mode with windows sharepoint. Since this installation the drillthrough reports have stopped working. We get the following error when a hyperlink is cllicked:-
The item 'http://vtrends/reports/IslandRegionCountryState' cannot be found. (rsItemNotFound)
In the textbox properties we have set the 'Jump to Report' hyperlink option to use a condition. Based on the link clicked, one of two reports will be displayed. If i remove this condition and manually select the report to run then there are no problems. This however is not the functionality that is needed. Any help will be appreciated.
We are looking at going down the High Availability Always On route. However we have some concerns around the lack of support for MSDTC. In short we are concerned that developers may introduce functionality either on purpose or by mistake that uses the or escalates the Query’s to the MSTDTC. As this could result in database splitting.
Understand that this will be a moot point in SQL 2016 but for 20122014 is it possible to disable the MSDTC to protect against this and run High Availability Always On. ? Does it just need to be disabled on the SQL Server or does it need to be done on the application server ?
