APAR status
Closed as program error.
Error description
When a user un-registers a deployment manager (dmgr) from a job manager, and the job manager and dmgr are the same JVM, it can cause the trust.p12 file of the dmgr to become an empty file. The next start of the dmgr might then fail as follows: java.io.IOException: Keystore file exists, but is empty: /opt/IBM/WebSphere/AppServer/profiles/Dmgr01/config/cells/Cell01 /trust.p12 ....
Local fix
After de-registering, the dmgr profile can be recovered by simply by copying the trust.p12 file in the profile directory: cp -p /etc/trust.p12 /opt/IBM/WebSphere/AppServer/profiles/Dmgr01/config/cells/ Cell01/trust.p12 Then the dmgr will start up without error.
Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server V8.0 and V8.5 * **************************************************************** * PROBLEM DESCRIPTION: Unregistering a deployment manager * * from a job manager can introduce a * * dmgr startup failure. * **************************************************************** * RECOMMENDATION: * **************************************************************** Unregistering a dmgr from a jobmgr can introduce a dmgr startup failure when the two entities are in the same JVM.
Problem conclusion
Part of deregistering is to remove the certificates of the dmgr from the job manager, since it is assumed they will no longer need to be communicating with each other. However, when these two entities are the same JVM, this can result in an empty truststore, which prevents server startup if security is enabled. The code is revised to detect when a dmgr is deregistering from itself, and not remove the certificates in that case. The fix for this APAR is currently targeted for inclusion in fix packs 8.0.0.10 and 8.5.5.3. Please refer to the Recommended Updates page for delivery information: http://www.ibm.com/support/docview.wss?rs=180&uid=swg27004980
Temporary fix
There is usually a copy of the trust.p12 file in the (profile_root)/etc directory. It can be copied over the damaged file, then the dmgr. will start.
