Query Time Outs

[Ryan Budge]

Hi All.

I have some rather large SQL Server 2000 databases (around 60GB).

I have set up jobs to re-index the tables and update statistics every
sunday. This worked will for a few months. Now after a day or two of
using it the connections to it keep timing out. If i start the jobs
manually, all is well for two days or so.

Surely there can be a better solution to this ?

TIA.

Are the timeouts happening on the tables or on the queries run against
the tables ? The tables shouldn't time out. The queries could well
time out. Try running your queries with the execution plan showing. It
may give you some indication of what is causing the delays.

Also, do you get the same results on each PC and the server ? Try
running the query on the server if possible to see if it is server
based or networking. Networking issues may be causing a bottleneck
which then slows you down. Worth looking at if possible.

The trick will be narrowing this down to where the problem actually
lies, not just where it shows up.

OK. Will do.
Also, do you get the same results on each PC and the server ? Try

I have tested the application on the server and on client PCs. It
does not seem to make a difference. Timeouts and slow performance is
on both...

Yep... Im sure. :-).

I remeber googling around or reading some of the books online and
reading about the sample percentage when updating statics and indexes.
Is it possible to re-index a table with a greater percentage to
enable the job to only run once a week ?

What kinda percentage is safe to use ?
Thanks for the suggestions.
