blocking alerts

Is there a way to create an alert when a query is blocked for however long I
choose? I know I can query the SysProcesses table but that will just tell me
who is blocked right now, not who has been blocked for say 60 seconds.

TIA, ChrisR
Hi,
There is no build in functionality to alert for blocks based on some time.
Only way is to create a table and insert the contents of
blocked SPID's based on some intervals (say 60 seconds). After that
implement the logic to alert by querying the new table.
Thanks

Blocking Alert

I'm trying to set up an alert for when a block occurs on a database. I
thought I could use error 1229, but that doesn't appear to be the correct
one, as it never fires, even tho we do get an occassional block.
Is there another error number I should be using? Is it possible to do what
I'm trying to do? Ideally, I would like an email to be sent when a block
occurs, so I can analyze the situation and make necessary changes.
Thanks for any advice,
TomT
Tom,
Are you refering to a database lock or a lock on an object in the database
that might be causing blocking? Might want to check out the SQL Server
Agent - Performance Condition Alerts - SQL Server:Locks.

Thanks for your response. I'm talking about a block that shows up in EM,
under Current Activity\Process Info. There's a column for Blocking and
Blocked By.

thanks very much for the link. Out of curiosity, is it possible to also set
an alert for this? Is there to your knowledge a specific error number for

Blocking is not really an error condition. It's a normal part of RDBMS
operation. You are always going to have blocking going on in some
fashion. In a healthly system, the blocks are so short they are never
noticed. On a system with problems these blocks are more pronounced. The
blocking scipts Sue mentioned will help you determine when extended
blocks are occurring in the database.
You can set a lock timeout in you application if you want. With a lock
timeout, the application will only wait for a specific maximum time when
blocked before cancelling the query. A cancelled query throws an
attention event, which can be captured with Profiler or using a
server-side trace.

Blocking

Can a Performance Alert be set up to detect blocking on a server? We do not get deadlocks but we do get a bit of blocking going on and it
would be nice to be notified when blocking is occurring.Originally posted by ToddBritt
Can a Performance Alert be set up to detect blocking on a server? We do not get deadlocks but we do get a bit of blocking going on and it
would be nice to be notified when blocking is occurring.

You can acheive this by using a combination of Scheduled Tasks, stored procedures and Alerts.

Write a stored procedure that generates a user-defined error message whenever there is blocking. Blocking can be checked by querying the sysprocesses system table.

Define a scheduled task that runs this stored procedure for every n minutes.

Define an Alert on the specific error message and configure it to send a mail.
