Seems like only 1GB RAM being used even when higher MAX RAM is spe
Have a server with 4GB RAM, running Win2K server, SQL2000 SE. I have not
implemented any /3GB, PQE or AWE switches because of the obvious OS and SQL
version limitations.
When I open Enterprise manager > SQL Server Properties > General tab, I see
"OS memory: 3775(MB)", which seems to be close to the 4GB physically
installed. I figure the difference is overhead, etc.
I have tinkered with the Memory settings, including a "Dynamically
configure..." range, and a fixed memory size. I've tried just about every
permutation to try and cajole it into using more than the 1GB it seems to
only want to use. There are probably better places to check how much memory
it is using besides the Task Manager, however, the Task Manager shows 1069mb
(just over 1GB) for sqlserver.exe. So, I figure that even if Task Manager
isn't the most accurate, it probably isn't off by a factor of 2. How can I
get SQL to use the 2GB it's supposed to be able to use? I can tell you that
the performance of this server is really bad (and there are many other
opportunities for improvement - the subject of another interesting
discussion) but with such bad performance, wouldn't it try to use more memory
- especially when serving a 30GB+ database? There has to be something I'm
missing.
Thanks in advance,
Larry

RE: Seems like only 1GB RAM being used even when higher MAX RAM is spe
Task Manager is not a reliable tool to tell you the amount of memory SQL
Server is using. Use performance monitor instead. In performance monitor,
select counter SQLServer:Memory Manager \ Total Server Manager (KB). This
counter shows the amount of memory used by the SQL Server buffer pool, which
accounts for most of the memory used by SQL Server.

Re: Seems like only 1GB RAM being used even when higher MAX RAM is
Thanks,
I made that change:
sp_configure 'set working set size',0
reconfigure
(restarted sqlserver.exe)
confirmed current runtime setting = 0
Ran a bunch of huge queries, large transactions, beat up the server, etc...
Memory usage still seems stuck at right at 1,062Mb.
Anyone, anyone, anyone ? :)

Re: Seems like only 1GB RAM being used even when higher MAX RAM is
Well something certainly isn't adding up here. What are the values of both
the target and total server memory for the SQL Server memory counters? How
much free memory does Perfmon show? If you really are querying more than
2GB worth of different data you should see the memory usage go to about
1.7GB with that configuration. I see the Max Memory was set to ~3GB which
is more than what you have but just to rule it out you may want to rest that
back to the default of the max as well. Are you sure there isn't some other
app on the server that may be eating up memory? Are there any settings in
the boot.ini that are not default? You should really think about upgrading
the OS and SQL Server in the near future anyway. Std edition in 2005 & 2008
can use the max memory that the OS can access and if there was anything
funky with the OS or SQL builds an upgrade should surely fix that.

Re: Seems like only 1GB RAM being used even when higher MAX RAM is
Yes, it does not add up.
I just reconfirmed all of this.
Here is boot.ini:
--------------------------------------
[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(2)\WINNT
[operating systems]
multi(0)disk(0)rdisk(0)partition(2)\WINNT="Microsoft Windows 2000 Server"
/fastdetect
--------------------------------------
Perfmon shows available MBytes = 2148
so 2Gb are just sitting there.
I made the changes you suggested (set min = 0, max = 2Gb), and restarted sql
service. I run a halacious join query and watch the memory increase,
increase,increase, and then in task manager it gets stuck at its usual
1062Mb, which is consistent with the PerfMon shows. Then in PerfMon, the
%Disk Time goes through the roof. This is what happens ALL the time,
regardless of what settings are changed.
Your suggestion to move to later versions is valid, but I don't see why I
can't get THIS server to use at least 2Gb (or 1.7Gb who's counting?) !!!
Does Microsoft have any ideas?
Thanks,
Larry

Actually I said to put the max back at the default which is 2147483647. No
tthat I think it is the problem but just wanted to eliminate it. If SQL is
taking 1GB and there is 2GB left where is the other 1GB going? What does
task manager say is using that other GB?
The only other thing I can think of is that someone set the -g startup
option to a non-default value as well. If you look at the server properties
in EM you can see the startup options. See if there is a -g and if so what
the value is. If it is more than 256 you might want to question why and that
will be the problem. If not I suggest you contact MS PSS so they can log
into your system and have a look. Other than the AWE issue with SP4 I have
not seen any bugs that would cause this behavior. Please let us know what
you come up with.

Re: Seems like only 1GB RAM being used even when higher MAX RAM is
Hi Larry,
I think that there are some misunderstandings among these posts. Though you set your SQL
Server to use a fixed memory size, SQL Server will not initially allocate 2GB memory on startup
or when your SQL Server does not really consume so much memory. Fixed memory means that
your SQL Server can use the memory to the fixed size and will not release/increase the memory
after the memory reaches to the fixed size.
From SQL Server Books Online, http://msdn.microsoft.com/en-us/library/aa196734
(SQL.80).aspx, we can find the following description regarding "min server memory":
Use min server memory to guarantee a minimum amount of memory to an instance of SQL
Server. SQL Server will not immediately allocate the amount of memory specified in min server
memory on startup. However, after memory usage has reached this value due to client load,
SQL Server cannot free memory from the allocated buffer pool unless the value of min server
memory is reduced.
Then we look back to your issue, I noticed that you changed the your SQL Server to use min=0
and max=2GB, in this case, SQL Server will dynamically allocate memory and it is usual that
SQL Server will sometimes release memory though it has not reached to the maximum memory
size. Please still set your SQL Server's min and max memory to the same size 2 GB and wait to
see the memory situation when there are many heavy workload.
Hope this helps. If you have any other questions or concerns, please feel free to let me know.
Have a nice day~!

Charles Wang

Re: Seems like only 1GB RAM being used even when higher MAX RAM is
Startup Parameters:
-d, -e, -l
no -g.
sp_configure
max server memory (MG) = 2047
Now, that 2047 matches the setting I put into the Dynamic Memory, Max
setting in Ent Mgr for SQL. Of course, this doesn't match your setting of
2147483647 which is some very large number (2Tb?), so I did this:
sp_configure 'max server memory', 2147483647
reconfigure
I will restart sqlservr.exe at the lunch break when I can kick everyone off.
I will repost near end of day.
Thanks

Re: Seems like only 1GB RAM being used even when higher MAX RAM is
Thanks Charles. I understand that I should not expect the memory to
instantly reach the minimum. That is not the problem. The problem is that
it never exceeds 1Gb even though the I/O to the F-drive (where the data files
are stored) is totally maxxed-out. Now, this is a big database, and even 2Gb
will not be enough for some of the queries in this system (which are also
being evaluated for performance as a separate project), but having 2Gb will
certainly be better than 1Gb. I can assure you that the problem is not that
the memory is not needed. It is needed. I'm confident that this 30Gb+
database could use much more than even 2Gb to run at its best. (And as a
separate project, we're evaluating new hardware, Win2008 and SQL2008, so no
need to mention those options.) I'm trying to alleviate the pain in the
short term.
The problem is that no matter which settings I put in place (so far), I
can't get SQLSERVR to use more than 1Gb. No matter which settings, it will
never exceed 1Gb. No matter what I put in for min or max, etc, it will never
exceed 1Gb RAM even though there are complex queries running throughout the
day. I can run a single complex query on one of the bigger tables (250K
rows) with lots of joins, etc, and I can literally watch the memory increase.
It goes 100M, 200M, ......800M, 900M, 1000M, 1069M and then it just stays at
1069M even though the query is still running for several more minutes. And
during this time when the RAM is stuck at 1069M, the disk utilization goes to
700%, which would indicate lots of paging from RAM to disk, so I'm sure that
if SQL could get access to it, it would use more than 1GB, so I hope I have
clearly shown that the problem is not that SQL does not need the RAM.

Larry

Did you look to see what Task manager shows the other 1GB being used for?
Are their any other apps (other than normal windows services etc.) running

Re: Seems like only 1GB RAM being used even when higher MAX RAM is
I'm following this thread and the problem is really interesting.
However, in your following reply, I wish you'd tell us the "Total Server
Memory" and "Target Server Memory" counters' results.
I know, you gave us lots of proves about the memory consumption. But the
results of these counters would definitely prove you had enough RAM but SQL
Server can't take advantage of it.

Re: Seems like only 1GB RAM being used even when higher MAX RAM is
Hi Larry,
Thank you for your detail response for clarifying the issue.
So your real concern is that your SQL Server can only consume maximum 1069MB physical memory on your server that has actually 4GB memory, though you had configured your SQL Server to
use minimum 2GB memory. Your expectation is to have your SQL Server use almost 2GB memory.
If I have misunderstood, please let me know.
By design, Windows OS will cover 2GB memory for system use and the left 2GB memory is for all Windows applications. SQL Server is one of those applications and it should be normal that it
cannot utilize the maximum 2GB memory since other applications or services will also consume some memory. Could you please check how much memory is used other applications running on
your server?
If there are some heavy load T-SQL queries, I recommend that you enable /3GB switch in the Boot.ini file on your Windows Server, for example:
[Operating Systems]
multi(0)disk(0)rdisk(0)partition(2)\WINNT="Microsoft Windows Server 2003" /fastdetect /3GB
In this case, Windows OS will keep 1GB for OS and leave 3GB for user mode applications. After that configure your SQL Server minimum memory to 2GB.
Hope this helps.

Re: Seems like only 1GB RAM being used even when higher MAX RAM is
Yes, it appears you understand the situation perfectly.
There are no other significant applications that run on this server. It is
not a domain controller, nor an IIS Server, nor a DNS server, etc. The
largest memory allocation in task manager is sqlservr.exe at 1,064Mb, with
rtvscan.exe a distant second at 52Mb.
Total Mem Usage (task manager): 1411372K / 5794148K (of course the amount
above the 4Gb is the pagefile.)
In this case, if all apps were to share the 2Gb, then I would expect
sqlserver.exe to at least be using around 1.7Gb calculated as 2Gb (available
for all Windows applications) - 1411372 (current total usage) + (1067400
current sql usage) = 1.66Gb for sqlservr.exe. (Yes, I know I've rounded
badly and it is all to the advantage of reduced space for sqlservr.exe for
sake of argument, so no need to clarify that a Gb is > 1000Mb, etc)
So after all this, there is still no explanation that sqlservr.exe is not
using all the memory it should.
Next I will try the 3Gb option and see what happens....even though
theoretically, I shouldn't need to do this - but I'm willing to try just
about anything.

Re: Seems like only 1GB RAM being used even when higher MAX RAM is
Everything you're saying about how much memory is being used, seems to be
evidenced only from Task Manager. A couple of questions have asked about
what performance monitor says about total server memory and target server
memory, but I haven't seen your answer to those questions. I'd also be
curious about what is reported under the MSSQL:Memory Manager/Buffer Manager
counters. (I never trust Task Manager to really tell me how much memory is
being used by SQL Server... it usually lumps the higher memory allocated to
SQL Server into PF usage instead. Performance Monitor does not try to pull
the wool over your eyes like this.)
Also, are there any observable symptoms that make you believe that less RAM
is being used? I didn't review every single message in the thread but I
don't see anything about actual performance problems. I'm not always a fan
of "it ain't broke, don't fix it" but if you have no actual symptoms of
insufficient memory, and are chasing this just because you saw the number in
task manager and didn't like it...

Re: Seems like only 1GB RAM being used even when higher MAX RAM is
Hi Larry,
Thank you for your response.
I am sorry that after long discussions under this thread, I omitted that your server was Windows 2000 Server. Indeed /3GB switch and PAE are not supported on Windows 2000 server. In this
case, you can only enable AWE for your SQL Server to allow it to consume more than 2GB memory. I read through the posts again and noticed that Adrew had recommended that you enabled
AWE, however it seemed that you did not do it but just configure "set working set size". Please try running the following command:
sp_configure 'show advanced options', 1
RECONFIGURE
GO
sp_configure 'awe enabled', 1
RECONFIGURE
GO
sp_configure 'max server memory', 4000
RECONFIGURE
GO
sp_configure 'min server memory', 2000
RECONFIGURE
GO
If this still could not help you resolve the issue, please make a call to Microsoft Customer Support Services (CSS) for deeply troubleshooting this issue. Please feel free to let me know if you have
any other questions or concerns. Have a nice day!

Re: Seems like only 1GB RAM being used even when higher MAX RAM is
Earlier in the thread, all memory usage shown in task manager has been
verified by using the PerfMon to look at memory usage in addition to many
other parameters (paging, disk %, etc, typically used to troubleshoot a SQL
server) Because of the consistent correlation between what Task manager is
showing and PerfMon is showing, I've just been referencing Task Manager since
an earlier post in this thread because it is easier to pull up. If total
usage in the system is 1.4Gb (including all OS, etc), then it is clear that
SQL can't be using all 2Gb (or even 1.7Gb) RAM. But thanks for your input.
The most difficult problems always turn out to be the most satisfying to
solve.

Re: Seems like only 1GB RAM being used even when higher MAX RAM is
We also had similar situtaion where SqlServer 2000 was using the complete
memeory installed in the server. We have dual core CPU with windows 2003 os.
If your machine is 32 bit your system will never use more than 2 gb RAM per
cpu. So server won't allow SQL to use more than 2gb per CPU. And if it is 64
bit machine than it will use more than 2 gb of RAM per CPU.
As we have dual core machine and had installed 8 gb RAM but 4 gb is just
lying and it is used at all. I may be out of synch but hope this helps to
reduce your problem.

Re: Seems like only 1GB RAM being used even when higher MAX RAM is
You may want to check out /3GB, AWE and /PAE (32bit).
http://support.microsoft.com/kb/274750
http://technet.microsoft.com/en-us/library/bb124810.aspx
http://msdn.microsoft.com/en-us/library/ms810461.aspx
http://www.microsoft.com/whdc/system/platform/server/PAE/default.mspx
Setting min = max is "fixed memory" in SQL Server 2000.
The OS takes ~300mb off the top for OS functions.
Assuming you did not limit SQL Server memory...
On a 3GB or 4GB system SQL Server will take ~1.7gb.
If you apply the /3GB switch to the boot.ini on a 4gb system SQL will take
~2.7gb.
If you have more than 4gb of physical memory the extended memory is
non-paged pool.

Re: Seems like only 1GB RAM being used even when higher MAX RAM is
First of all, it's not me who is experiencing this problem. The OP is
someone else.
Regarding to your scenario, you said your SQL Server 2000 instance is
installed on a Windows Server 2003 OS.
If your SQL Server 2000 is Enterprise Edition and your Windows Server 2003
is also Enterprise Edition then you can take advantage of your 8GB of RAM.

Re: Seems like only 1GB RAM being used even when higher MAX RAM is
It is Sql 200 enterprise, 2003 Enterprise edition. And we have a cluster of
dual core server(32 bit). Both machines are equipped with 8gb of RAM. We have
tried all sort of option but still sql is unable to use more 1.5 - 1.7 gb per
CPU.
The userbase of our application is 1500+ and it is database oriented
application so we see heavy traffic in the application. As such we don't have
any issues with anything but I don't know why it does not go more than 2gb.
I will try the URL sent by you. Hopefully it will solve the problem.

Re: Seems like only 1GB RAM being used even when higher MAX RAM is
Yes if you really do have Enterprise editions of both the OS and SQL Server
you can use AWE and PAE to access more than 2GB as per the documentation
listed.
