Sql Server Memory Dynamic Or Fixed?
Jun 8, 2007
I have a person who just recomended to a customer to use Fixed instead of Dynamic for the SQL Server Memory setting informing me that I was wrong for setting it to use Dynamic.
Well I tried to explain that why would you want to give away memory if you do not need to, he just answered that I was wrong, any help in proving me wrong or him wrong?
Which way is the correct way. I was told by a very bright person with a strong background in the developement of SQL that when it was written it was done so with the word "fixed" memory size was done in lower case just as a reminder that you can but should never use "fixed" that you should always use Dynamic (which by the way does use a capitol "D"...)
Just wondering...Thanks for the help guys...
This is the personal edition running on the XP Pro platform for use in a Point-of-Sale enviorment with 6 other computers connecting to hte SQL server on the one back of house computer which is running 4mb of memory.
I told them that the minimum should be at zero and the max is set to half....

Hi,
I am going to install SQL Server 2000 (then SQL 2K5) on a Win Server 2K3 with 8 GB of ram, but it will be 16 GB in the near future.
I would like to reserve a fixed memory (for momemt less than 3-4 GB) for SQL Server and the rest for application (virtualization).
Without AWE enabled, max memory for SQL Server 2K5 is 4GB as for SQL Server 2000?
How can I manage and optimize memory keeping in mind AWE. (any doc, website available?)
Thank

We have a SQL enterprise server 2014 with two installed instance.
First instance for SharePoint 2013 DBs and second instance Dynamics AX 2012 R3 DBs.
The server has 32 GB of RAM, currently the process usage for first instance is 26 GB and second instance is 700 MB.
Which mean that SharePoint DBs in the first instance is consuming most of the RAM.
My question is there any way to assign a fixed RAM usage for a specific instance without affecting the other instance?
for example 16 GB only first instance and 16 GB to second instance.

Does anyone mess with this feature? they say that you don't have to change this setting in sql2000. I have 3 gigs of memory and have it still set to dynamically configure the memory. I don't know if i should change this to a fixed memory size, if i did how do you tell what value to set it at? What are the pros and cons if I set it to fixed? Thanks.

I have a table with 3 columns (ID Int , Name Varchar(25), Course Varchar(20))
My source data looks like below
ID Name Course
1 A Java
1 A C++
2 B Java
2 B SQL Server
2 B .Net
2 B SAP
3 C Oracle
My Output should look like below...
ID Name Course(1) Course(2) Course(3) Course(4)
1 A Java C++
2 B Java SQL Server .Net SAP
3 C Oracle
Basically need t-sql to Convert non fixed rows to non fixed columns...
Rule: IF each ID and Name have more than 1 course then show it in new columns as course(1) course(2)..Course(n)
Create SQL:
Create table Sample (ID Int null , Name Varchar(25) null, Course Varchar(20) null)
Insert SQL:
INSERT Sample (ID, Name, Course)
VALUES (1,'A','Java'),
(1,'A','C++'),
(2,'B','Java'),
(2,'B','SQL Server'),
(2,'B','.Net'),
(2,'B','SAP'),
(3,'C','Oracle')

I have gotten mixed comments on this topic. I have a 64 bit machine running 64 windows 2003 standard and 64 SQL 2005 standard with 8 GB of RAM. We want to upgrade it to 32 GB. What is the best approach to do this? Dynamic or Stattic giving min and max server memory a value ? and if static what value should I use for 32 GB knowing that this box is only being used for SQL.

Hi
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?

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 ??
thank you

I need to change one of the column to run utctime 2am. Whenever I declared and set the time, it has to run and set up to the UTC 2 am time.
How to declare the variable like that?
If I run that now, it has to set up next utc 2 am time, If I run after 2 hrs also or tomorrow whenever, it has to set the next utc 2am time

Hello all,
On Analysis Services 2005 the members of the Administrators local group are also members of the fixed server role, therefore they have full control over Analysis Services databases.
I think this can be a problem becouse many system administrators don't need full control over AS. Does someone kwon how can I remove those high privileges to the local administrator?
Thank you.
Hernan.

Hi there. I work in a support department and on great occasion (such as this morning), I am RASd in to a client and try running a SQL trace, only to receive an error when setting it up, 'In order to run a trace against SQL Server you have to be amember of sysadmin fixed server role.'
Today, I even called their DBA and asked him if he could set our userid up with the proper permissions to all us to run traces (I'm debugging a RTE). He stated that he was unfamiliar with the error and didn't know where to assign us to resolve this problem.
Does anyone know how to resolve this?
Many thx.

I wasn't sure where to put this topic so I put it here since I figured it is a question that would apply to virtually any version even though I am using SQL Server 2005.
We have a vendor that sends us a fixed width text file every day that needs to be imported to our database in 3 different tables. I am trying to import all of the data to a staging table and then plan on merging/inserting select data from the staging table to the 3 tables. The file has 77 columns of data and 20,000+ records. I created an XML format file which I sampled below:
<?xml version="1.0"?>
<BCPFORMAT xmlns="http://schemas.microsoft.com/sqlserver/2004/bulkload/format" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<RECORD>
<FIELD ID="RetNo" xsi:type="CharFixed" LENGTH="6"/>
[Code] ....
The data file is a fixed width file with no column delimiters or row delimiters that I can tell. When I run the following insert statement I get the error below it.
BULK INSERT myStagingTable
FROM '.........myDataSource.txt'
WITH (
FORMATFILE = '.........myFormatFile.xml',
ERRORFILE = '.........errorlog.log'
);
Here is the error:
Msg 4832, Level 16, State 1, Line 1
Bulk load: An unexpected end of file was encountered in the data file.
Msg 7399, Level 16, State 1, Line 1
The OLE DB provider "BULK" for linked server "(null)" reported an error. The provider did not give any information about the error.
Msg 7330, Level 16, State 2, Line 1
Cannot fetch a row from OLE DB provider "BULK" for linked server "(null)".

I have this doubt and want to be sure if my thinking is correct.
Lets consider 2 tables one with Fixed length columns (char) and other table with Variable length columns (Varchar).
The table with fixed length column will always allocate same size within a Page however, table with variable length column will allocate actual length of data within a page.
I think that updates happening on table with fixed length columns will have more possibility of InPlace updates at least from data length perspective, however updates on table with variable length columns will have more split updates from data length perspective.

Edition: SQL Server 2005 Standard
I am trying to take a snapshot of a database for use in a publication. The account under which the snapshot agent is running is set to have the db_owner role for the database and have write access to the snapshot share.
I can not get the snapshot to run unless the account under which the snapshot agent is running is granted the sysadmin fixed server role. Because of the security implications of this, I don't want to grant these permissions.
As far as I am concerned, the minimum requirements for the snapshot account have been met and I have tried every other alternate that I can think of. I've checked MSDN and the newsgroups but I still have not solved the problem.
The error that I get when I run the snapshot.exe from the command line is:
The remote server "TURING" does not exist, or has not been designated as a valid Publisher, or you may not have permission to see available Publishers.
This error message has now inexplicably changed to:
You do not have sufficient permissions to run the command...
Any ideas? Thanks.

We would like to use the bulk insert function to import large CSV files into a SSE database however we have serious concerns regarding giving all our users these high privleges. Is there some way around this can we give them the privleges temporarily do the insert and take it away again or some other solution.

I am looking to test this feature - and the "Transaction Performance Collector" has recommended me a table to port to In-Memory OLTP.
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?

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.

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?
Thanks,
fshguo.

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?
Thanks! Aaron B.

My server is a dual AMD x64 2.19 GHz with 8 GB RAM running under Windows Server 2003 Enterprise Edition with service pack 1 installed. We have SQL 2000 32-bit Enterprise installed in the default instance. AWE is enabled using Dynamically configured SQL Server memory with 6215 MB minimum memory and 6656 maximum memory settings.
I have now installed, side-by-side, SQL Server 2005 Enterprise Edition in a separate named instance. Everything is running fine but I believe SQL Server2005 could run faster and need to ensure I am giving it plenty of resources. I realize AWE is not needed with SQL Server 2005 and I have seen suggestions to grant the SQL Server account the 'lock pages in memory' rights. This box only runs the SQL 2000 and SQL 2005 server databases and I would like to ensure, if possible, that each is splitting the available memory equally, at least until we can retire SQL Server 2000 next year. Any suggestions?

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.
