RE: slow update and db trigger
Ravindra, The possibilities could be vary, but my curiosity, it's coming from your trigger database. My experience when using trigger database, it makes slow processes, so I never use it anymore.

Re: slow update and db trigger
It could also be a dynamic recompile issue. Make sure the triggers and proc. are valid before each test.

Re: slow update and db trigger
It sounds like the triggers / procedures may have different logic depending on the row being updated. Or possibly the same logic results in a large number of rows being queried / modified by one of the procedures. Have you looked at the trigger and procedures to understand what they are doing? There may be opportunities to tune them. Perhaps you could trace the session to see what is happening, but it might be easier to look at the code. Regards, Mark.

slow update and db trigger
I have an update statement executed by a procedure.This update statements fires a trigger which has a set of update statements and also executes 2 procedures. If i execute the parent update statement which will affect a single row from a table which has significantly less number of rows.This statement sometimes is executed very fast and sometimes it takes upto 50 seconds.Does this slowness got to do anything with the triggers that get fired automatically .For me this update is a single piece of transaction.Why do i see the delay in this update statements.
