exclude tempdb from your monitoring... all you need to monitor on this system db is growth and make sure it has enough disk space to grow into since it's very dynamic

keeping it simple...

you will not be able to control the tempdb growth like the other databases

you need to find out what's making it grow to 2gb, if there are batch jobs, then you may need to schedule them evenly across the day,
if there are transactions requesting for very large datasets, you may want to advise your developers to divide the results
otherwise, expand your hd to accomodate the growth,

once the transactions have been committed, you will see that it will shrink back



When you says, "once the transactions have been committed, you will see that it will shrink back", you mean we dont need to manually shrink the tempdb?

If so, why its not shrinking for below example.

Tempdb - datafile initial size is 5 MB
Autogrow - 10 %

Create temp table
insert data into temp table till tempdb datafile reach 15 MB
drop temp table

Now if I checks the size of tempdb data file its still 15 MB

Restart the SQL instance

Tempdb data file is 5 MB.

We have a daily monitoring tool for SQL Servers. It cannot fetch details for tempdb. E.g. one of the queries fired is :

select b.groupname,sum(a.used)
from sysindexes a, sysfilegroups b
where a.groupid =* b.groupid
and (a.indid = 0 or a.indid = 1 or a.indid = 255)
group by b.groupname

It causes blocking. Next tiem (after 5 mins) when the same query is piles up the lock requests and tempdb does not respond to any request.

Please note that the query works fine,when used with NOLOCK hint.
ALso, the same query is working fine with all other databases on the server.

Please suggest.

what does "sp_who2" show??
