Hello there,
I am experiencing performance problems with an aplication running over a SQL
Server 2000 Database. The server that holds SQL Server has 2.8 GB of RAM
memory. When there are just on or two users working, the aplication
performance is suportable, but when more users are using the aplication,
there picks when its almost impossible work normaly.
My question is: what can possible cause this loss of performance?
All workstations have an ODBC connection with 'sa' user. Can it be
important?
What can I do to troubleshoot this problem?
The are serveral important tables with many fields and many records. I think
that I have created indexes correctly.
Can anybody help me? Thanks.
Regards,
Marco Pais
Usually the causes are bad design, poorly written queries, and
poor/inadequate indexing. BOL has a lot of trouble-shooting information
under the topic "Troubleshooting". You probably want to look at blocking
first.

|||There are lots of things it can be and you need to narrow down the
possibilities. Blocking does indeed sound like a good possibility. Try
running sp_who2 when you have multiple users in the slow state and see if
any show up with a spid in the Blcked by column. These articles should help
to get you going in the right direction.

What can I do to troubleshoot this problem?

Yes it's very important, although it has nothing to do with
performance. If user applications connect as a system administrator
then security is non-existent - one rogue user, faulty piece of code or
malicious hack could destroy your database and your server.

This is almost certainly a code problem. It could be the application is
keeping locks for far longer than necessary. It could be your queries have
changed enough that your indices don't work as well.

As David mentions, this is a HUGE security risk. Not only can users do
anything to the db, they can do anything to the OS.
With the XP_CMDSHELL command they can create domain users, add them to the
domain admin group and take over your system.
> What can I do to troubleshoot this problem?
Simplest, look at output of sp_who2 active and look for blocking. If it's
there consistently, that's your biggest problem. Eliminate it.
Use dbcc inputbuffer(spid) on the blocking spid to see what the code looks
like.
If this doesn't help, time to break out profiler.

Giving them "sa" access unless it is "absolutely" necessary
is just plain insane from a security perspective. However,
that doesn't address your problem.
Can you give us some guidance on whether you have
indexed your tables, how large they are, when was the
last time the hard drive was defragged, when was the
last time you reindexed the indexes.
There could be a ton of things that need to be addressed.
Sounds like you are a bit of a beginner to managing SQL

that doesn't address your problem.
Can you give us some guidance on whether you have
indexed your tables, how large they are, when was the
last time the hard drive was defragged, when was the
last time you reindexed the indexes.
There could be a ton of things that need to be addressed.
Sounds like you are a bit of a beginner to managing SQL
Server databases, these free flash video presentations might
help:

Database performance
Hello there,
I am experiencing performance problems with an aplication running over a SQL
Server 2000 Database. The server that holds SQL Server has 2.8 GB of RAM
memory. When there are just on or two users working, the aplication
performance is suportable, but when more users are using the aplication,
there picks when its almost impossible work normaly.
My question is: what can possible cause this loss of performance?
All workstations have an ODBC connection with 'sa' user. Can it be
important?
What can I do to troubleshoot this problem?
The are serveral important tables with many fields and many records. I think
that I have created indexes correctly.
Can anybody help me? Thanks.

Marco PaisGiving them "sa" access unless it is "absolutely" necessary
is just plain insane from a security perspective. However,
that doesn't address your problem.
