We use CM Repository in Portal (version 7.0 sp21) for an attachment of documents in Bex (web pages).
When in system there is more than 300 sessions that a portal to hang. In the session monitor (st04) I see much (more than 20) following record:
SID = 377
Event = enq: TX - row lock contention
SQL Statement = DELETE FROM u201CKMC_DBRM_TMPNODES"
There are locking while delete of data. The long turn from blocking is built. And portal to go down.
Please let me know how to solve a problem of lock table?
