RDBPROD: OpenVMS 8.3-1H1 patch may be required to address Deadlock detection fault (Doc ID 1416394.1)

Last updated on JULY 28, 2016

Applies to:

Oracle Rdb Server on OpenVMS - Version 7.1 and later
Oracle CODASYL DBMS - Version 7.1 and later
HP OpenVMS Itanium

Symptoms

Deadlock detection may not occur for a lock, resulting in hanging processes.

Processes may be seen in a deadlock using $RMU/SHOW STATISTICS (or $DBO/SHOW STATISTICS) in the STALL MESSAGES screen, or using $RMU/SHOW LOCK/MODE=BLOCK (or $DBO/SHOW LOCK/MODE=BLOCK).  The deadlock is undetected by the Distributed Lock Manager.

Stopping one of the processes is usually required to resolve the deadlock.
