Error: 16954, Severity: 10, State: 1 and Timeout problem

Hi to all,

I have a problem I can not trace.
Andgeneraly this is my problem probably.

I have a SQL Server 2000 SP3 with one database.
On this DB are runing lot of threads from different applications. So
the access is multiple.

The problem is, on one of the applications (C++ programmed) I get from
time to time, problem, that the calls in database are sometimes
performed very very long.

If usualy it takes like 50ms, sometimes it takes up to over one minute!

I can not trace, why the application need so long time, to perform this
statement.
I've checked the code, but it seams to be ok.
Probably, other aplication are locking resources, so the first one need
to wait so long.

Question is, how to find out, which one is locking the resources, or
maybe which resources for so long?

I was trying to analyze SQL Profiler, but the only error I found was
this one:

Error: 16954, Severity: 10, State: 1

Help me, how to diagnose the problem. How can I trace, which processes
are blocking eachother.

Any advise will be helpful..

The text for this message is "Executing SQL directly; no cursor."

You could try my aba_lockinfo. This stored procedure gives you a
snapshot of what is going on. Which processes that are active,
which are blocking and which are block. You get what they lock,
what they are waiting for, and their current statement. You find it on
http://www.sommarskog.se/sqlutil/aba_lockinfo.html.

Error: [Microsoft][ODBC SQL Server Driver] Timeout Expired

I am getting above error msg when I tried to run my View.
The view have 12 tables and 20 joins, which tells you the complaxcity of
the view. When run this view using Query Analyzer it gave me the above
msg as well and then i update timeout property within QA. After
updating the timeout property, the view run fine. I need the same
changes in Enterprise Manager and update timeout property for the server
but it still not working.
Help!
Many Thanks

Do you have appropriate indexes on the tables involved, especially on the
columns used for the joins?
