Hello all,
I have a Production server which has 2gb of memory. SQL server memory is set to configure dynamically.
The Server also has a third party application on it. The third party application was running poorly, and the software vendors recommended running the following sql on a job every hour:-
exec sp_configue 'max server memory(MB)',500
reconfigure
exec sp_configure 'max server memory(MB)'1400
reconfigure
The hourly job has the effect of flushing out sql server memory every hour and setting the max amount down to 500mb and back up to 1400mb. SQL server still manages memory dynamically, so within the hour before the next time the job runs, sql server could use more than 1400mb.
I' feel that this job will degrade sql server performance because it will empty the buffer cache and procedure cache. My approach would be to select the 'use a fixed memory' option and set it to 1400mb, and not use their recommendation.
Does anybody have experience of this, and perhaps explain the consequence of running the recommended job every hour.
Any advice would be great.

So I started a new job recently and have noticed a few strange configurations. Typically I would never mess with min memory per query option and index create memory option configuration because i just haven't seen any need to. My typical thought is that if it isn't broke... They have been modified on every single server in my environment.
From Books Online: • This option is an advanced option and should be changed only by an experienced database administrator or certified SQL Server technician. • The index create memory option is self-configuring and usually works without requiring adjustment. However, if you experience difficulties creating indexes, consider increasing the value of this option from its run value.
Hi~, I have 3 questions about memory based bulk copy.
1. What is the limitation count of IRowsetFastLoad::InsertRow() method before IRowsetFastLoad::Commit(true)? For example, how much insert row at below sample?(the max value of nCount) for(i=0 ; i<nCount ; i++) { pIFastLoad->InsertRow(hAccessor, (void*)(&BulkData)); }
2. In above code sample, isn't there method of inserting prepared array at once directly(BulkData array, not for loop)
3. In OLE DB memory based bulk copy, what is the equivalent of below's T-SQL bulk copy option ? BULK INSERT database_name.schema_name.table_name FROM 'data_file' WITH (ROWS_PER_BATCH = rows_per_batch, TABLOCK);
------------------------------------------------------- My solution is like this. Is it correct?
// CoCreateInstance(...); // Data source // Create session
I'm setting up a new production SQL 2005 64-bit server running on a dedicated Windows 2003 R2 Standard system w/8GB of RAM.
I've enabled the "Lock Pages in Memory" option (http://msdn2.microsoft.com/en-us/library/ms190730.aspx) but when I run dbcc memorystatus all of my AWE counters show 0.
According to http://blogs.msdn.com/sqlprogrammability/:
"On 64 bit machines, execute 'dbcc memorystatus'. If the AWE Allocated memory is 0 then lock pages in memory privilege has not been granted to the service account or it has not taken effect. "
Does the "Lock Pages in Memory" option work on W2K3 R2 Standard? Just searching across the web I find different answers. In some places it clearly says that Lock Pages in Memory only works on W2K3 Enterprise systems. In other places it says that it should work on any Windows 2003 64-bit OS.
Does anyone have any ideas? Assuming we cannot "lock pages in memory" due to the Windows 2003 Standard OS, are there any other memory management recommendations out there?
Hi everyone In my SqlServer Management Studio Express, on start up it shows the server type option, but greyed.So that value is fixed to database engine. ( I'm trying to work on an SqlServer Compact Edition database through the SSMStudiothat's why I'm trying to get this to change.)Besides, after I connect i go to the Object Explorer, expand the server node, and go to Replication.When i expand replication, i get the "Local Subscription" option, but nothng for Publication.( I want to work on Merge Replication, that's why I desparately need Publication to work)Am i missing something here? I did not install SqlServer separately, I only have what comes bundled with the Visual Studio 2005 Setup.
Hello. I have received the follwoing error upon an attempt to Browse the Cube. All other tabs are functional, including the Calculations tab. We are running Windows Server 2003 SP2 and SQL Server 2005 SP2. Any suggestions would be greatly appreciated!
**EDIT** - Have confirmed SP1 for VS2005 is installed both locally and on server, also.
Attempted to read or write protected memory. This is often an indication that other memory is corrupt. (Microsoft Visual Studio)

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.
I have a Windows sever 2012 with sql server 2012 enterprise. Ram size is 22GB. Sometimes SQL sever takes 95% memory.My question, How to reduce memory size without killing any process because it's production server.So there are many background process is running. And,Is there any guides to learn why Memory is raise d so high and how to reduce it.
Hello, I understand that we should use SSMS -> Server Properties -> Memory to put a cap on the SQL server memory usage, therefore it gives some space memory for OS, this is based on the fact if the max memory is not specified, SQL will use whatever available memory and eventually crash the system.
My question is that when a server has SSIS and SSAS services installed along with the SQL service. Would the max memory setting covers the SSIS and SSAS memory usage, or the SSIS and SSAS has to shared the memory with OS?
I am running Visual Studio 2005. I have an SSIS Package which is consuming a huge amount of memory. During the execution of the package the memory keeps increasing. Until finally i get an Out of Memory exception. I have run this package using dtexec, and in the BIDS. No difference. I do have some script components and have added some code to get the assemblies in the current appdomain. I do see that one particular assembly is increasing on every loop. VBAssembly every time it hits the script component is increasing by 6, and along with it the memory is climbing. What is this VBAssembly being used for is there an update to SQL Server Integration Services that I need?
sql server 2000 is running on windows server 2003 ... 4gb of memory on server .... 2003 was allocated 2.3gb nd sql server was allocated (and using all of it) 1.6gb for total of approx 4gb based on idera monitor software ... all memory allocated betweeen the OS and sql server .... then 4 more gb of memory added for total now of 8g ... now idera monitor shows 1.7gb for OS and 1.0 gb for sql server ..... 'system' info shows 8gb memory with PAE ... so I assume that the full 8gb can now be addressed .... why are less resources being used now with more total memory .... especially sql server ..... i thought about specifying a minimum memmry for sql server but i amnot convinced that would even work since it seems that this 1gb limit is artificial .... it it used 1.6 gb before why would it not use at least that much now ??
I've a database with a memory optimized filegroup on it. How can I remove it?I have removed the memory optimized table I had on it, but when I try to remove the filegroup I receive an error.
I did a load testing and found the following observations:
1. The Memory:Pages/sec was crossing the limit beyond 20.
2. The Target Server Memory was always greater than Total Server Memory
Seeing the above data it seems to be memory pressure. But I found that AvailableMemory was always above 200 MB. Also Buffer Cache HitRatio was close to 99.99. What could be the reason for the above behavior?
Guys , I have a dedicated server ... I've installed SQL SERVER 2005 and I have a problem to connect to SQL from local machines in the office ... Remote connections are on , server BRowser starts automatically ... for example from remote machinne I mean from Server where SQL is installed I can connect to SQL ... FireWall i've turned off.... What can be the problem ????
Hi, I got a website and everything works fine with SQL Server 2000, but now I modified the way of authentication using Forms and when I enter in a protected area I got this error: An error has occurred while establishing a connection to the server.When connecting to SQL Server 2005, this failure may be caused by thefact that under the default settings SQL Server does not allow remoteconnections. (provider: Named Pipes Provider, error: 40 - Could notopen a connection to SQL Server) The problem is that I don´t have SQL Server 2005 installed so I don´t know why my webapp is trying to contact it, where I can configure this settings so it will look for the Server that exists? Thanks.
In my DAL, I have 3 tables - Footballer (FootballerID = Primary Key) Aspnet Membership Table (UserID=Primary Key) Favourite Footballers (Junction Table with 2 Primary Keys FootballerID and UserID - both with foreign relationships to their respective data table)
On my sports site, visitors can view various footballers and store their favourites in th FavouriteFootballers Table by clicking on a button. This stores the Logged in UserID and FootballerID in the junction table. I now need to write a select query that allows users to click a link and view their favourites which they stored - lets say in a data list on another aspx page. This would include other columns from the Footballer Table such as Name, Age, Profile ect I think I am right in that I need to use a Select clause as I am using SQl data adapters in the DAL. Be very pleased if someone knows how to contruct the query and give me an example how to code a method in the BLL Some code is below
Method that Stores FootballerID and UserIDprotected void DataList1_ItemCommand(object source, DataListCommandEventArgs e) {
// Assuming only have one button in the item templateInt32 fid = Int32.Parse(e.CommandArgument.ToString());Guid userid = (Guid)Membership.GetUser().ProviderUserKey;
// Connect to the db and insert the recordusing (SqlConnection con = new SqlConnection("Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\MyDatabase.mdf;Integrated Security=True;User Instance=True")) {
string query = string.Format("INSERT INTO FavouriteFootballer(UserID, ArtistID) VALUES('{0}',{1})", userid, fid); SqlCommand cmd = new SqlCommand(query, con); con.Open(); cmd.ExecuteNonQuery(); con.Close(); }
Code in FavouriteFootballersBLL Its not complete -withotu parameter - i think maybe I also need to reference the Footballer Table and not the Junction one [System.ComponentModel.DataObjectMethodAttribute(System.ComponentModel.DataObjectMethodType.Select, true)]public DataSet1.FavouriteFootballerDataTable GetFootballerFavourites() { return Adapter.GetFootballerFavourites(); }
Hi, I am really having a hard time creating a parameter for the RadioButtonList radSearchField. I want to type 's' in the text the choose the column for the query to execute the Select statement. I was able to create a parameter for the txtSearchText but can't get the radSearchField working. My form contains four objects.
Textbox to perform the query. (name: txtSearchText)
We've A2k db which we plan to migrate to SQL 7.0 very soon. Though am familiar with upsizing wizard BUT don't know how to configure Access forms, reports etc. to talk to SQL back end tables. So that information entered via Access forms can be stored in sql and reports can be generated using sql tables..
