Follow on from setting up Publisher in a clustered environment, I’ve found a nasty little bug in the scheduling element of Publisher, Quartz.
Looking at the oc4j log file /opmn/logs/default_group~home~default_group~1.log I can see OC4J starting up, and then a whole load of repeated messages:
09/03/30 11:28:43 Oracle Containers for J2EE 10g (10.1.3.3.0) initialized

Metalink to the rescue …. a search for “Search: ClusterManager: Scanning for instance” throws up doc 739623.1 - Repeated Error Appears In Log File - ClusterManager: detected 1 failed or restarted instances which details the problem and references bug # 7264646.
This is a bug in Quartz (the Publisher scheduling tool), which has been fixed in 1.5.2 (the version that’s included with Publisher is 1.5.1).
On my installation quartz was located in /j2ee/home/applications/xmlpserver/xmlpserver/WEB-INF/lib
Implenting the fix described on Metalink doc 739623.1 solved the problem.
