Greetings,

I am running Oracle EE 10.2.0.4.0 and using Data Guard (I'm not sure that is relevant) on RHEL 2.6.9-67.ELsmp x86_64. The upgrade to 10.2.0.4.0 was recent but as part of the upgrade migrated to new boxes and Data Guard. Within a couple of days after the upgrade we started seeing the following in the alert log...

Searching find several references to this error but nothing which specifically matches our situation and the reports cover other versions of Oracle as well. The error is generated intermittently and the query reported in the trace files is indicating updates to one particular table. I did find bug 7020582 which merely reports a bug after upgrade to 10.2.0.4.0 but it is apparently a bug in other releases and platforms. I have opened an SR and am waiting for a definitive answer. If anyone has any insights or suggestions for dealing with this I would appreciate it.

Thanks.
