SQL Express/SSRS Memory Limitations

Jul 18, 2007

Hello,

I am aware that SQL Express has a memory limitation of 1GB. I am trying to determine if this 1GB memory is shared with the Report Server. In other words, if I run a query that requires 600MB of memory, and a report that pushes the Report Server to 600MB of memory, will I exceed the 1GB limit for SQL Express? Or are these two separate processes for memory limitation purposes?

If they are separate processes, are there any limitations to the Report Server as far as performance when using the Express edition of SSRS? If not, would it not make sense to push the Report Server harder than the database when running reports if SQL Express is my target platform? (e.g., do MORE work in the RS, and less in the database itself)

Thanks,

Michael

SQL 2005 Express And CPU/Memory Limitations.

Jul 8, 2006

SQL Express Ed is limited to one CPU, what happens if the CPU is a dual core CPU? Does SQL Express care? Does it see a dual core as a single CPU?

As for memory, stupid question, SQL Express is limited to 1 GB RAM, if I run it on a server with say 4GB of ram packed into it, will it affect SQL Express' performance? Will SQL Express even run if there is more than 1GB available? Or will SQL Express simply ignore the extra RAM with no negative consequences?

Thanks,

Andy

In-Memory Processing Tables - Limitations?

Nov 11, 2014

Just been reading up on this and there are a lot of limitation which one needs to consider when designing an in-memory table. I'm going to post them below in the hope that others will add to them so I can get a definitive list;

No foreign key constraints

No clustered indexes

No schema changes once the table is set in memory

No index changes once the table is set in memory

Alter Table function is not supported

Additional filegroup needs to be created in order to process in-memory tables

Varchar MAX is not supported

XML/User Defined data types are not supported

Max page length is 8060 (page overflow not supported)

Memory Limitations, 2005 Standard

Mar 9, 2006

Hi all,I have recently implemented a SQL 2005 cluster using SQL 2005 Standardon Windows 2003 Enterprise edition.Both nodes have 4GB of RAM and according to the datasheet, SQL 2005Standard can support the OS maximum memory amount and Win2K3 EntEdition can support 64GB!However, in Enterprise Manager, if I go to the "Memory" tab of theinstance properties I can't increase the memory beyond 2147483647(which I assume is around 2GB).I don't have AWE enabled but am unsure as to the ramifications of this.Any advice anyone could provide would be greatly appreciated.Many thanks,Ian

SQLExpress Memory Limitations && Aspnet_wp.exe

Jul 24, 2007

Does the aspnet_wp.exe get considered in memory limitations for SQL Express? (1GB limit) I'm asking because I run the Reporting Services on the same box (this is required with SQLE). When I run reports, it seems much of the work is in the aspnet_wp.exe process, so I'm trying to determine if running reports will get considered in the 1GB memory limit of SQLE. I know, however, that the ReportServer database and the ReportServerTempDB database WILL get included in the 1GB limit, but am trying to figure out if the aspnet_wp.exe process gets considered as well when it is running reports.

Thanks,

Michael

SSRS Report Builder Limitations??

Nov 26, 2007

hello and hi to everyone.
Well we are planning to bundle SSRS 2005's Report Builder (with our own application) for user defined custom reports.
But there are couple of question i have before.
first What is the best practice of integrating the Report Builder with custom applications. Mean can i only write the triggers on Report Server Database which will tell me which report has been created and what is its server location so we can also add this link in our application to integrate that report with our system.
or there in any other good method.
The second question is that can i make a custom layout except the three(matrix, tabular etc ) already present in Report Builder. Ai want to give user that cusotm layout so he will not have to create layout first mean add images and custmize design.
waiting for a prompt reply from u peoples
thanks in advance.

Export Limitations In SSRS 2005

May 21, 2008

Is there a document/technical article/white paper, basically, some information as to what can be exported into a particular format and what cannot be.

I have a report which is fine when exporting to Excel but doesnt export to XML or CSV. All I get in XML or CSV is just a heading. I am thinking, may be its not right to export that report into XML or CSV formats.

Has this happened to anybody before? Any advise is appreciated.

SQL Express Limitations

Jun 6, 2006

Hi, I was curious if anyone knew if there was a way to get around SQL Express Edition 2005's limitations to support remote connections. If I install SQL Server 2005, will there be a smooth transition between the two on my IIS 5.1 server? My database is extremely simple and only consists of a single table without any complex queries. Idealy, I would like to spend no money since I am a poor collge student doing this as a project. Suggestions?

SQL Express RAM && CPU Limitations

Mar 10, 2008

With the limitation of 1Gb of ram and 1 CPU for SQL Express, does that mean we cannot load it on a server with multiple CPU's and more ram, or that we can load it and it will only use 1CPU and 1Gb of ram?

SQL Server Express Limitations

Jun 21, 2006

I was looking around, and I found this info on SQL Server Express:The 4 GB database size limit applies only to data files and not to log
files. However, there are no limits to the number of databases that can be
attached to the server.Does this mean I can use several different databases in my website, like one separate db containing forum entries, and one with user details and related stuff?

SQL Server Express - Size Limitations

Mar 13, 2007

Hi,

I am currently using the SQL Server Express edition with the intention of upgrading to the full version in the future.

I know the size limitation on the Database is 4GB - however does this include the log file as well? Nothing I read says the log file is included however if anyone can give the definitive answer I would be grateful.

Also my log file maximum is set to 2GB what issues are there with reducing this to say 500MB? I assume SQL Server automatically drops the old log data to add new data when the maximum is reached.

Thanks for your help.

I'm building an ASP.NET application using C# language and SQL Server 2000. This application is dedicated to be hosted on a VIsta Machine.Unfortunately Vista does not supports SQL SERVER 2000 so i must migrate to the SQL SERVER 2005. Since the application is a small application, we couldn't afford buying an SQL SERVER 2005 License so i decided to use SQL SERVER 2005 Express Edition. But i would like to know exactly what are the Limitation on the Express Edition to see if it will work with my application or No. Please Can anyone refer any document that describes in details all the limitation of the Express Edition ??? Thanks a lot.

SQL 2005 Express Memory Limits

Jun 26, 2007

Hi everybody,

I know that SQL2005 Express has 1 GB memory limitation.

Well, if my server has 2 GB RAM and I have other applications (without memory constraints) how does this relate to the SQL constraints ?

Can I still run SQL2005 Express if other applications exaust only 1 GigaByte of memory ?

Thank you in advance.

Does Memory Limit Cause SQL Express To Stop?

Mar 14, 2008

Hi,

I have a small sized db (size doesnt goes on 50mb - currently its 15mb ) on my computer and my application uses that db.

Normall SQL Service uses 50-60 mb of system memory.

But after some heavy usage SQL 2005 express Services memory usage goes near 1GB and sometimes SQL Service stops itself.

Does SQL 2005 express stops itself when it reaches the 1GB memory limitation?

Regards,

Restricting Memory Express Constumption

Aug 2, 2006

Hi

We are developing some applications for Sunit computers (In-vehicle computers) which have limited memory . Because the applications display maps, the will consume alot of memory. Because of this, we want to restrict the amount of memory and other resources SQL Server Express uses to a minimum. I've tried setting 'max server memory', which doesn't help too much as this is only a limit on the SQL engine and not the sqlserver.exe process. What other settings and restrictions can I apply to limit memory consumption by the process?

We have considered using SQL Server Everywhere, but as it doesn't support ODBC (will there be any ODBC support?), we are not too happy about using it. As of now, we have no experience with OLE DB, and the application is MFC 6.0 so we can't take advantage of ADO.NET

Best regards

SQL Express, Shared Memory, Domain Computer

Jul 16, 2007

I am new here and new to SQL Express. I've searched for my issue, but can 't quite find anything close to the problem or how to solve it, if it's even solvable. I am using SQL Express on a pc to connect to the back end of a database. The front end application (an access runtime) also runs on the same pc. This pc is on a domain. I think I've tried every combination of protocols, and although connectivity via ODBC is successful, the application can't connect - gives the "server doesn't exist or access denied". When I log on to this computer with the "machine" logon (not the domain), I have SQL Express configured to use shared memory, the application runs just fine. I need to use this database for testing in a non productivity environment, but I really hate to log off the domain to run it. Ideas?

Thanks,

SQL 2005 Express - Sqlserv.exe Memory Usage Always Increasing.

Nov 1, 2006

Hi,

I'm hoping that some might have an answer for me after much net searching.

I have a server (200GB disk space, Dual 3.8 GHZ processors, 4GB memory) that hosts 6, very small, SharePoint sites (WSS 2.0) and SQL 2005 express handling 1 config DB and 7 content DB's.
The biggest DB at the moment is only 300 MB and the sites are not actively being used yet, they are only open to a select number of users (+ - 25 in total) who are using them as reference "areas" at the moment. Each site is running in it's own application pool as well.

I find that the sqlserv.exe process increases in memory usage and does not seem to decrease. It gets to the point of 960 MB usage and then databases cannot be used (SQL 2005 Express max memory is 1GB). SQL seems to "close" them down and site errors being received are "site is not in configuration database". When the SQL service is restarted the memory usage idles around 70 - 80 MB, the sites are 100% again but after an hour or 2 the memory usage is sitting at 560 MB again and doesn't seem to decrease.

Is there a way I can bring this memory usage down?

Any feedback would be greatly appreciated.

Long Memory Grant Queue Waits In SQL Server Express SP2 Causes Slow Queries

Sep 10, 2007

I have a 2GHZ cpu with 1GB of RAM. I occassionally see very slow (long) queries against a local SQL Server 2005 Express (SP2) database. The issue occurs against different SQL Queries, but all queries are rather basic select statements Perfmon shows that the SQL Server counter for the "MEMORY GRANT QUEUE WAIT Avg MS" gets extremely high (25000+ ms). Perfmon also also shows that PAGING is not occuring, and the system is not under unsual stress. The problem is not reproducible with MSDE.

Has anyone seen this issue, or have any recommendations for a next course of action?

Using SSRS 0n SQL 2005 Express-can Not Connect To Report Server

I am using WIN XP PRO with IIS installed. Installation (including SSRS) seems OK.

If I go into new project and select Business Infomration / New Report I can select datasource, etc, design a and get to a deployment window. Default is Report Server: http://localhost/ReportServer Deployment Folder: Report Project2

I can preview a report just fine.

If I go to Debug or Deploy I get a error message box that starts with "A connection could not be made to the report server http://localhost/ReportServer"

Am I missing a component on my system or can you suggest something else I should look at?

Deploying SSRS In SQL Express Edition With Advanced Services

Aug 4, 2007

Hello, I am having a difficult time with a complicated task. I have developed numerous SSRS reports for my application and want to deploy these reports with my application. The application uses SQL Express Edition with Advanced Services. I have written an installer to automate this process, but my problem is getting the SSRS reports that I developed on my server incorporated into the ReportServer database created during the install of SQL Express Edition with Advanced Services. I have read numerous good posts and articles regarding the rsconfig.exe and rskeymgmt.exe utilities, but I am having problems. The main problem seems to be dealing with the encryption key. I have done a restore of the ReportServer database using a backup of the ReportServer database I used to develop my SSRS reports. This worked well with the exception that I can't seem to get past an error message stating that reportiong services has not been initialized. Keep in mind, I need an automated way to do this. Anyway, I have tried using rskeymgmt to restore a backed up copy of the encryption file that I took from the server where I developed the reports. I get an error message that scale-out deployment is not supported in this version or something like that. I can't delete the encrypted data because then the connection information for my shared data source is deleted also. Again, please keep in mind I need all of this to occur behind the scenes during an install without end-user intervention.

Anyways, sorry for such a long post. I would appreciate any help anyone may be able to provide.

SQL Server 2000 As Data Source For SSRS 2005 Express

Hi,

We are in the process of upgrading a SQL Server 2000 database to 2005. For the mean time, we're trying it out on SQL Server Express 2005. My question is, can reports in SSRS 2005 pull data from SQL Server 2000 in case both are installed side by side in the same machine and the 2000 version is the default instance while the 2005 express edition is the named instance?

Thanks a lot!

SQL In-Memory :: Table Memory Optimization Advisor Validation Passed But Cannot Migrate

I have now tried the "Table Memory Optimization Advisor" tool.

After a couple of tweaks to the table design - the tool is now passing validation but the tool is not allowing to progress to the next step:

Could it be down to not having enough memory? But would this not show in the advisor?

AWE/Lock Page In Memory Drawbacks? Min/Max Settings, Memory Issues

Oct 11, 2007

I've been researching AWE to determine if we should enable this for our environment.

Currently we have a quad core box with 4 gb of RAM (VMware). OS: Windows 2003 std, SQL Server 2005 std. 3GB is not set but will be as soon as we can perform maintenance on the server.

I have read mixed feedback on AWE, either it works great or grinds you to a hault. I would assume that the grinding to a hault is due to not setting the min/max values correctly or not enabling the lock page in memory setting.

We only have one instance of SQL on the server and this box won't be used for anything else aside from hosting SQL services. We do plan on running SSRS off of this server as well.

1. Will running SSRS and enabling AWE cause me problems? Will I have to reduce the max setting by the SSRS memory usage or will it share and play nice?

2. How do I go about setting the Max value? Should it be less than the physical RAM in the box? Right now its set to the default of 214748364, even if I don't enable AWE should this default value be changed?

3. It seems that even at idle the SQL server holds a lot of memory and the page file grows. If I restart the process in the morning, memory usage in taskmon is at 600mb or so. By the end of the day, its up around 2gb. How can I track down whats causing this, should this even concern me?

4. The lock Page in memory setting worries me. Everything I've read on this seems to give a warning about serious OS and other program support degradation. In some cases to the point where they have to restore the settings on the server before they can bring it back up. What are your thoughts on this.

Limitations In SQL?

Feb 27, 2006

I'm new to SQL so don't laugh if this is easy to spot but I'm having trouble with a select statement but I do not think it's the syntax etc, I'm convinced it must be due to some restrictions and limitations within SQL.

Could anyone shed some light? I've been 'googling' for two days now and can't find anything, much appreciated! thanks.

SELECT a.medno_id,
tblAction.action_shortdesc,
tblClassification.class_shortdesc,
tblType.type_shortdesc,
tblUnit.unit_shortdesc,
tblSystem.system_shortdesc,
a.med_oldserial,
a.med_builddate,
tblLibrary.lib_shortdesc,
a.med_f24bookno,
a.med_f24entry,
a.med_f102bookno,
a.med_f102entry,
tblTransport.trans_shortdesc,
a.med_courierno,
tblPOC.poc_surname,
a.med_title,
a.med_notes

FROM tblMedia a

INNER JOIN tblAction ON a.action_id = tblAction.action_id
INNER JOIN tblClassification ON a.class_id = tblClassification.class_id
INNER JOIN tblType ON a.type_id = tblType.type_id
INNER JOIN tblUnit ON a.unit_id = tblUnit.unit_id
INNER JOIN tblSystem ON a.system_id = tblSystem.system_id
INNER JOIN tblLibrary ON a.lib_id = tblLibrary.lib_id
INNER JOIN tblTransport ON a.trans_id = tblTransport.trans_id
INNER JOIN tblPOC ON a.poc_id = tblPOC.poc_id

WHERE a.medno_id = 327
ORDER BY a.med_effdate

I've spaced out the query so it's easy to read

I've started the query from scratch building my SQL adding one field at a time and it works perfect until it reaches a certain number of fields, it's as if SQL has a limit to no of fields it can return/be used in the select part of the statement. Are there any limitations I should know about? or am I being an idiot and doing something I shouldn't?

Hope this makes sense, thanks!
