Why are we getting repeated lock wait warnings on the SCM.CONTENT_CLAIMER table?


Michael Walker (99213192157) | asked May 07 '13, 1:51 a.m.
We started getting multiple lock wait warnings each hour recently against one of our RTC  backend databases in DB2.  The statement is LOCK TABLE SCM.CONTENT_CLAIMER IN SHARE MODE. 

What are the possible reasons that this is occurring?  Is this multiple people or applications trying to check-out the same file and one user already has the lock?

I looked at the rows inside that table but couldn't get an idea exactly what it's used for.

This wouldn't be caused by multiple users loading the same content or having a file locked. This looks like a problem at the database level. I suggest taking a look at the tuning guide or contacting IBM support.
