APAR status
Closed as program error.
Error description
Starting two daemons causes a failure to attach to shared memory for at least one of them resulting in an ABEND of the daemon.
Local fix
Ensure that only one daemon is started at a time and make sure that it has completed start-up before starting other servers that might cause a daemon to be started.
Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server V9.0 for z/OS * **************************************************************** * PROBLEM DESCRIPTION: ABENDCC3/ABENDSCC3 reason code * * C9C20008 in a WebSphere Application * * Server for z/OS daemon. * **************************************************************** * RECOMMENDATION: * **************************************************************** One of two daemons starting at the same time can get an abend CC3 reason code C9C20008 because it is not attached to the shared memory that was allocated by the other daemon. The area that did not get attached to is BBODBGVT_BBOAOCNP. Both daemons saw BBODBGVT_BBOAOCNP was zero and were trying to set it with CSG. The daemon where the CSG failed continued along without attaching to the area created by the other daemon. This can happen when WAS_DAEMON_ONLY_enable_adapter is set to true.
Problem conclusion
Changed the code to attach to the shared memory that was created by another daemon. The fix for this APAR is targeted for inclusion in fix pack 9.0.5.16. For more information, see 'Recommended Updates for WebSphere Application Server': https://www.ibm.com/support/pages/node/715553
