Local fix
Problem summary
**************************************************************** * USERS AFFECTED: All Db2 11 and 12 for z/OS users * * that uses "LOCK Table in Share * * Mode" in their applications. * **************************************************************** * PROBLEM DESCRIPTION: ABND=04E-00C90101 in DSNISRTI with * * ERQUAL5003 on Insert. * **************************************************************** * RECOMMENDATION: * **************************************************************** When lock escalation happens on the X page (or row) locks, the lock state in its page Set Control Block(PSCB) will be set to X to indicate the page set is in X-lock state. But "LOCK TABLE in SHARE MODE" issued after the lock escalation mistakenly change it from X to S state. This caused the Insert to fail at DSNISRTI:5003 later.
Problem conclusion
Fixes made for "LOCK TABLE in Share MODE", so the correct lock state will be set in its Page Set Control Block.
Temporary fix
