Problem summary
**************************************************************** * USERS AFFECTED: All CICS users. * **************************************************************** * PROBLEM DESCRIPTION: Abend US0002 (code x'0307') in * * module DFHUSAD when executing * * a DELETE_USER call. * **************************************************************** * RECOMMENDATION: * **************************************************************** A transaction becomes suspended in DFHUSAD's DELETE_USER routine waiting for exclusive access to the USADLOCK lock which is currently held by another task. . While suspended, the task is FORCEPURGED. The lock manager call returns a PURGED response and the lock is not obtained by the task. . However on exit from the DELETE_USER routine, the code incorrectly assumes that the lock will always be obtained and therefore issues an UNLOCK request. This will fail and the trace entry "US 0307 USAD Unlock-error" is produced followed by an US0002 system dump. Additional keywords msgDFHUS0002 DFHUS0002 0307
Problem conclusion
DFHUSAD's DELETE_USER routine has been amended to issue the UNLOCK request only if the LOCK was successful.
