DB Engine :: MAX And MIN Server Memory Settings For 2012?
Sep 8, 2015
We have a new set up on VM to run an application running 24*7 (migrated from SQL server 2008R2) with below configs:
1. OS- Windows server 2012 Standard 64 bit hosted on Virtual Machine
2. Memory 16 GB and Cores =4 with 2.4GhZ processor
3. SQL server 2012 SP2 , 64 bit Standard edition.
4. Total size of databases as of now 15 GB with biggest being 5 GB.
How should i go around in setting the MAX and MIN server memory settings. I have this set up for many of SQL 2005 and 2008R2 servers, but for 2012 i heard that things has slightly changed.
How should i start analyzing and setting the right value of this MAX and MIN?
On first Node A: The server has 16 GB of physical RAM. On second Node B: The server has 10 GB of physical RAM.
Now, this being Active Active, Node A can be clustered on failure onto Node B..Now reporting server is configured under these two nodes, with defined MAX and MIN server memory of 12 as MAX and 0 is min IN GB.Now with this setting on SQL whenever the cluster moves, such config make OS goes low on node for 10 GB.I am only left with option of switching this MAX and MIN to a default setting or is there any other alternative such as script which can change this setting accordingly when cluster moves to respective server.
We have SQL Server 2005 Entp 32-bit on Windows Server 2003 Entp.Edtion 64-bit. ( Total memory = 16 Gb)
1) So, in this case , do i need to enable AWE Configuration from SQL Server Side ( 32-bit).
And what settings( AWE, /PAE) i should enable on OS (i.e.) on Windows Server 2003 (64-bit) in boot.ini file. Because right now, i dont see any switches in boot.ini file.
2) And with 16 GB of RAM, what should be the ideal setting for memory ( Min & Max).
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'm having trouble finding the optimum memory settings for SQL Server 2005. I have 4 instances running on a macine with 8 dual-core processors and 18GB of RAM. I have tried the following memory settings so far:
No maximum - one instance used about 12GB of RAM so then the others struggled Maximum of 4GB each (2GB left for Windows) - meant that 3 instances could be using 1GB each and then another at 4GB and needing more whilst 9GB sat unused. Minimum of 2GB each - one instance would use up 10GB and then never give any back to the other instances.
I also find that setting a maximum then just causes a high amount of paging. What I would like to do is have each instance use a minimum amount, say 1GB, and then have each instance use a maximum of 13GB (3GB for other 3 instances running at a minimum level and 2GB for Windows). This 13GB should then be released and allocated to another instance when necessary, assuming it is no longer all being used. I do not want paging to occur if an instance reaches 13GB.
How do I go about configuring SQL Server to behave like this? Is it possible?
I have an Active/Active/Passive cluster with 64GB RAM on each node running SQL 2000 EE, AWE is enabled as well as the PAE switch, all is dandy with that.
Question: Should I configure each SQL Instance to have only a max mem usage of 32GB in the event both failover to the same node ? or will the memory allocation be handled without any issue if each node is configured to use 64GB ?
So I'm in the middle of building SQL Server 2005 on my new cluster hardware. I've got all the goodies this time around -4x PowerEdge 68004x dual core x64 procs in each box32GB ram in each boxWindows Server 2k3 R2 Enterprise x64 SP2SQL 2005 Enterprise x64 SP2Active Active Active Passive cluster (4 boxes, 3 instances)dedicated data, log, and tempDB 4Gb 15k fiber channel SAN Volumes for each instanceNow, this is the first x64 box I've configured, so I'm looking for some optimization tips for a couple things.First one's memory. On our 32bit systems, I always added the /PAE switch to the boot.ini file and enable AWE in SQL Server. From what I'm reading, that's no longer needed with the enhanced memory addressing. Is that the case? Is there an MS best practices KB doc in regards to configuration? I can't find one.Also, should I set anything special pagefile-wise? I know the old mantra is 1.5x system memory, but that would create a 48GB page file. Our current cluster has 6GB of ram dedicated to each instance (2k) and Perfmon tells me it's barely touching the pagefile. I'm thinking of just leaving it default, but I want to know if there is a best practice that I'm missing. Again, I can't find an MS doc that addresses this particular scenario.
I have SQL 2005 Enterprise 64bit SP2 on windows 2003 EE 64bit SP2 w/24gig memory. My problem is that it wont use more than 110mb of memory according to task manager processes and performance. I've tried messing with the min and max and rebooting each time I make the change and sill nothing. Currently Ive changed it back to default. The server shows up as 24gig so it is seeing the memory. Any ideas? I thought 64bit was supposed to be better about this kind of thing.
Also, AWE has always been unchecked as this is a 64bit box.
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 have .bak file downloaded from internet , and i also have istalled sql server 2012.my problem that i can not restore this .bak file and get this error massage :
System.Data.SqlClient.SqlError: The operating system returned the error '5(Access is denied.)' while attempting 'RestoreContainer::ValidateTargetForCreation' on 'C:Program FilesMicrosoft SQL ServerMSSQL10_50.MSSQLSERVERMSSQLDATASRO_VT_SHARD.mdf'.

In my SQL Server Errorlog, I see the below error. The system has 8 GB of RAM with enough free RAM, something I can do to prevent this alert? (Note: I have no MIN/MAX memory set on this Instance)

I have a SQL Server at version Microsoft SQL Server 2012 - 11.0.5343.0 (X64)

I need to apply a cumulative update, either CU2 or CU3 for a third party tool used for monitoring to work. When I try to apply CU2 or any subsequent CU there is nothing that need the update so I cannot advance the version to 11.00.5548.
I am new to SQL Server 2012 clustering.I added a new instance to one of the two nodes.when I try to move it to the other node it fails.Do I need to install it on both?If so, what options do you install on the second node?
SQL Server 2012.If I create a table with 307 columns, all of type nvarchar(50), it works. If I add another column of type nvarchar(50), it works but I get a warning:
Warning: The table "RowSizeError" has been created, but its maximum row size exceeds the allowed maximum of 8060 bytes. INSERT or UPDATE to this table will fail if the resulting row exceeds the size limit.
307 x 50 = 15350 and 308 x 50 = 15400. why I get the warning below with 308 columns but not with 307?
drop table [RowSizeError] go CREATE TABLE [RowSizeError]( [F1] [nvarchar](50) NULL, [F2] [nvarchar](50) NULL, [F3] [nvarchar](50) NULL,
I have an XML file about 25MB. When I read it with openrowset it gives me 'System.OutOfMemoryException'. The machine I'm running has 16GB of RAM and memory is definetely not exceeded. When I run smaller XML files it works fine.
I've read that older versions of SQL Server had this problem and it was caused by the parser having limited amount of memory. Is this still the case? Is there a way to change this?
I used sql server 2012 express Import and Export Data (32-bit) wizard to import data from excel 2010 to a given table.

I am trying to reproduce a problem that is probably related to how a particular SQL server is configured. Is there a tool or best practice that is useful to compare all of the configuration settings between two SQL Servers (same version)?
We changed the IP addresses for several SQL Servers and we're a little confused by what we see in Configuration Manager. The TCP/IP properties "IP Addresses" tab still shows the old IP address, even after a restart. On "Protocol" tab, Listen All is set to "Yes".
We've found one source that says this setting causes the listening on an individual IP to be ignored.
We have Windows Server 2008R2 installed on VM Server.On that we have three SQL instances running. From few past months we are observing physical memory is going high. Earlier we observed it was at 86-88%, now it is 96-97%.We have 16RAM & 8 CPU cores on VM. what is the best and ideal configuration so that we can rectify the high physical memory issue.
I have a report that uses three tables from a database. As long as I only use two of the tables, it runs fine. I need the data from the third table for a line chart. So of course there is a great deal of data in the third table. I have a where clause for start date and end date. Is there a way I could only search the third table after I know what I need from it? Or
I have around 100 packages (all [packages run at same time) each package calls a stored Procedure once the Stored proc Execution is completed the package will write the log information into a log table, here how can i capture the CPU and Memory usage for execution of each stored proc.
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?
I have a VM set up for offloading DBCC checks. Specs are below. I've read through this, but I'm not seeing the performance gains by enabling the trace flags and using the physical only switch.
Is the whole drawback that I'm on SATA storage? Is there a VM configuration with the CPU I can/should change? I've been playing with MAXDOP trying to see if I can get any benefits but I'm not seeing a much.
Eager to know to set the Max Value of Maxtransfersize and Buffercount adjustment but also anxious to know Physical memory impact.URL...The max size that can be used is the (Buffer Pool’s To Physical Memory / 16). As returned from the GlobalMemoryStatusEx (ullTotalPhys ) API call. HereBob dorr saysBuffer Pool’s To Physical Memory/16 what it means? (ie. Buffer Pool/ Physical memory/16.0 or (Physical Memory - buffer pool)/16
