Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

As of Monday morning I have an OVM management server that is refusing to authenticate any user. Nobody admits to have changed anything on the server over the weekend. The server is fully patched using the public Oracle yum server. The oc4j log file regularly (every 15 minutes) prints out an error message that's maybe 400 lines long.

Here's the tail end of the oc4j log file:

11/06/10 13:42:25 java.lang.NullPointerException 11/06/10 13:42:25 at oracle.ovs.biz.db.SessionFactory.acquireSession(SessionFactory.java:338) 11/06/10 13:42:25 at oracle.ovs.biz.serverPool.ServerPoolSyncDaemon.runBusiness(ServerPoolSyncDaemon.java:305) 11/06/10 13:42:25 at oracle.ovs.daemon.CronDaemon$BusinessThread.run(CronDaemon.java:289) 2011-06-10 13:42:25.639 ERROR ServerPoolSyncDaemon.runBusiness:Failed to clear databaseSyncFlag,null

Also, I cannot authenticate using the cli utility ovm. If I type "ovm shell" and then enter the admin credentials, they fail. –  mr.zog Jun 10 '11 at 14:44

I have manually unlocked the admin account several times using sqlpro but it becomes locked again in a few minutes. –  mr.zog Jun 10 '11 at 15:06
    
I ran a sql script that checked for free space in tablespace. Does anyone know (from looking at the lines below) whether I have run out of tablespace?
