Issue
When you run an OPatch Update job, sometimes it might fail with the following error:
2011-11-28 10:31:19,127 RemoteJobWorker 20236 ERROR em.jobs startDownload.772- OpatchUpdateLatest: java.lang.NullPointerException: Category, 'Oracle Software Updates', has no child named, 'OPatch' at oracle.sysman.emInternalSDK.core.patch.util. ComponentUtil.getComponentCategory (ComponentUtil.java:854)
Even after applying the Cloud Control patch released in January 2012, you might see the following error:
Category, 'Oracle Software Updates' already exists.
