I am in the middle of capturing a workload to try and tune a SQL instance and was wondering what kinds of sizes people capture in terms of traces. I am only 1 day into a capture and I believe a typical workload would be a week long capture and I am already at 10GB of files. I am only capturing rpc_completed and sql_batch_completed.
What sizes of workloads do other people capture and then where do you analyse them, do you have particular dedicated server for this kind of thing as at present I am looking to use my local PC. Also what rollover file sizes do people tend to use, I am currently using 1GB.

what the ideal CPU count and Max Degree of Parallelism are for a 3rd party database server.The server has 12 CPUs, 32GB RAM and all database sizes add up to < 30GB so they can all fit in memory (I tried to force this by doing a select * from every table). On certain payroll days, the CPU gets maxed out to 100% for a few seconds.
MAXDOP was originally set to the default 0. We later changed it to 8 based on several 'best-practices' articles. However the vendor suggests to change it to 1 (no parallelism), while others suggest changing it to 4, so that one run-away query doesn't hog most of the CPUs.
I'd like to find out how many CPUs are actually being used by queries. There is a Degree of Parallelism event in URL.... The BinaryData column says :
0x00000000, indicates a serial plan running in serial.
0x01000000, indicates a parallel plan running in serial.
>= 0x02000000 indicates a parallel plan running in parallel.- What does "parallel plan running in serial" mean ?
I see a lot of 0x01000000, and a few 0x08000000's in my trace.How can i determine whether one query is hogging CPUs and if reducing it to 4 will work?

Somehow someone turned on a audit on the sql server and it is filling up our hard drive and shutting down sql server eventually. Been trying to google how to shut this audit off but coming up with no via soolution yet. how can I turn this trace off. Each fiel says AuditTrace and date and they happen every other minute. I went into the sql profiler and can pull up the files but how to shut the trace off, it does not say.

Is there a way to setup a trace to show only direct TSQL statements triggered on my server? note I don't want to capture Procedure calls or the statements called within the procs.
Actually many people are firing direct SQL statements on server. And some are coming from entity framework as well. I just want to capture those.

I am attempting to create a new trace but I get the following error message: "failed to start a new trace".
I have been doing some digging and as I understand it, I had to find the directory Profiler uses for temporary files. So, I typed the following in the command window "SET TMP" and I received the following reply:
C:UsersRossAppDataLocalTemp
Now, according to the forum: [URL] ...
I am supposed to check that the system folder pointed to by the TMP environment variable exists and is not crammed with files.
Well, when I went to the directory C:UsersRossAppDataLocalTemp, it is indeed full of both files and directories. The size is 16.3 MB and has 133 files and 63 folders.
When I had a look at the Environment Variables window and chose TMP the value is "%USERPROFILE%AppDataLocalTemp" which according to my limited understanding is the equivalent to C:UsersRossAppDataLocalTemp.
So, what I am wondering is am I supposed to totally clear out this directory? I am not too keen on doing this because I don't want to stuff my PC up.

Set up a trace with the events RPC:Completed, SQL:BatchCompleted, SQL:BatchStarting, and SQL:StmtCompleted.
When I issue the statement: SELECT * FROM XyzView there is nothing captured in Profiler. If I script out the view and then execute the select statement that defines the view, it does show up in Profiler.
I've tried adding a lot of the other events, i.e. SP:StmtCompleted and the various other StmtStarting events and the trace still does not capture anything.
Am I capturing the wrong events or is this known behavior? My goal is to see what the overhead is for using a view versus persisting the results of the view as a table and referencing that instead. The view in question is against static data, joins 9 tables, and is referenced a lot.
I can use the stats generated when I execute the select that defines the view but I still find this to be curious behavior so I assume I'm doing something wrong.

Is there a dbcc flag that will capture all error messages in the log
e.g. when inserting data into a table, a PK violation occurs throwing, Msg 2627
..similar to trace flag 1222 to capture deadlock info..

After carefully analyzing the situation for almost a month, I pulled the trigger and made an exception at work; we did enable trace flag 2371. We have some tables with billion of rows and outdated statistics causing horrible plans. Tried several methods to update those, but did not solve the problem or was too CPU intensive, causing other issues.
Anyway, one of the side effects I am seeing so far is average vCPU went down by almost 40%. Nothing out of usual (besides the flag) has been enabled or was executed. So my assumption is, CPU hungry plans are now gone or reduced.

I am upgrading my application's SQL Server from 2008 R2 to 2012.
As discussed in the below URL I am able to see the Identity jump after I upgrade and the server is restarted.
Now since I cannot afford this and at this moment I do not have the time to create a sequence with NOCACHE and test it again I have to go ahead and add trace flag 272 in the start up parameter as this is the only solution which I can implement and even rollback without much hassles.
[URL] ....
What I got to know, this flag will disable the new feature of IDENTITY property that has been implemented as part of SQL Server 2012 and will make it work like it was doing in SQL Server 2008 R2.
But I want to know implementing this flag would impact any other feature or performance (except the performance of IDENTITY) of SQL Server.

I am struggling figuring out the token from a CMDEXEC job (as opposed to TSQL Job). It is not an option to execute the command by enabling the executing CMDs via TSQL, which is why I am using the agent. I have seen the Microsoft Site on tokens but all examples seem to be oriented to TSQL Job Type.
I am trying to delete a particular trace file and at same time keeping the SQL Directory dynamic.Taking it a step further is adding in "deleting if file exist".
del $(ESCAPE_SQUOTE(SQLDIR)) + "LogTestTrace.trc"

After SQL server service restart, a column which is set to auto increment jumped 1000. To fix the issue, I had to add T272 trace flag to SQL startup parameters. However, I did not see the column being reseeded after the service restart, it is still showing the 1000 jump. Am I doing something wrong?
Below the log showing the flag being added to the error log:
LogDateProcessorInfoErrorMSG
2015-06-15 22:29:53.850ServerRegistry startup parameters:
-d E:DATAmaster.mdf
-e E:logERRORLOG
-l E:DATAmastlog.ldf

We have an SSAS instance where when we run the query "select * from $system.discover_traces" the creation time in the resultset shows a different time from when we actually started the trace.
for example if we have create the trace at 3.30pm it shows 7.35 pm in the Sql server management studio resultset when we run the query "select * from $system.discover_traces".

Hi,
I'm trying to debug a vendor package and would like to turn on JDBC trace (either client or server side). The only information I found is DBCC TRACE which seems not very useful (I even don't know where the trace result located). Any help is appreciated!
Env: Windows Server 2003 & SQL Server 2000 8.00.818.

hi all..
i have 2 tbl..
-- Prepare sample data
DECLARE@tbl1 TABLE (box varchar(10), loc varchar(5) )
INSERT@tbl1
SELECT'P1', 'aa' UNION ALL
SELECT'P1', 'bb' UNION ALL
SELECT'P1', 'aa' UNION ALL
SELECT'P3', 'cc'
DECLARE@tbl2 TABLE (box varchar(10), loc varchar(5) )
INSERT@tbl2
SELECT'P1', 'aa' UNION ALL
SELECT'P3', 'cc'
--expected result
SELECT 'P1' as box, 'aa' as Location, 'aa' as HeaderLoc UNION ALL
SELECT 'P1' as box, 'bb' as Location, 'aa' as HeaderLoc
how do i trace from @tbl1, that has 1 Box with more than 1 Location?
in this case P1 has 2 distinct location (aa & bb).. and left join in the loc from @tbl2 just to retrieve the loc for that box..

Hi ,
I want to trace the deadlock information. I am enabling trace flags 1204 ,1205. Is there any difference in setting these trace flags by using DBCC
TRACEON and by setting them at command prompt by statrting the SQL server with SQLSERVR command. Actually i don't want to bring the server down. I want the information to be logged to Error log. Any help is greatly appreciated.

Hi all,
I was wondering how much of an overhead would Running this
trace (1204) have over the system. Will my perfomance
degrade significantly. If yes, by what percentage ???
The trace is 1204 to keep a watch on DeadLocking
I am running this command
C:mssql7innsqlservr -T1204 /dc:mssql7datamaster.mdf
How much performance degrade are we talking about here ?
The Application is Peoplsoft and the db sizes is about 10
