Re: tempdb size question

On Apr 3, 7:29*am, "Krisnamour t via SQLMonster.com" <u21487@uwe>

TempDB is the soul of SQL and everything you can do to gain performance, do

See this article from Kimberly and try to make this configuration. You'll see
the diference!


For example, SQL OLTP with 4 processors, I create five files, 4 with the same
size without autogrow and the last one with the same size, but with autogrow
true, because we need to garantee space for any necessary task, but often we
don't need and we manager well this.

I know that, for OLTP, the rule of thumb for LOGS is around 25% of
database size.
What is the rule of thumb for TEMP size? *I know that its a good idea
(for TEMP) to have .25 to 1 data files per CPU, but how big should
TEMP be in total? *Whats the rule of thumb there? *I would assume its
some multiple of the total size of all databases in the instance?

-For a small db server that does about 10-20 GB of logging per day, I
would recommend having a size that does not go through AUTO_GROW. i.e
ensure that the size of tempdb is big enough that it will hold the
whole days work.

- for larger dbs, you need to come up with a cycle time that is
sufficient for your applications. i.e a 30 minute to 3 hour growth
between tempdb's log file ie zero'ed.

I keep getting the following error message when I run a serie of SQL commands: Server: Msg 9002, Level 17, State 6, Line 15 The log file for database 'tempdb' is full. Back up the transaction log for the database to free up some log space. I have tried "dump transaction tempdb with no_log" right before I run the SQL command. But that doesn't help.

Hi All, First, where can I get some questions of this sort answered? Preferably, are there good books or online guides that I can consult for these types of answers when necessary? 1. How do I know, when executing a query from Query Analyzer or otherwise, how many temporary tables will be needed, and how big they will be? 2. Where will those temporary tables be created? Always in tempdb?

has anyone met with this before? the setting is SQL2K with SP3 on a 2 node active-active W2K3 cluster. on one of the machine, it occasionally prompts for the following error: "The log file for database "tempdb" is full. Back up the transaction log for the database to free up some log space." the problem is, at the time of error, the tempdb tx log is only 200MB and there are over 50G disk space available.

I was able to find a few posts on this topic, but none of them quite seemed to fit the situation, so I'm hoping that someone else might be able to help me here. I have a client who is using SQL 2005 (sorry, don't have the exact build with me). They run a weekly process which causes TempDB to grow to over 100GB before it fails due to a full disk. Once it's grown to that size we can't seem to shrink it again short of restarting the server.
