Hello everyone, We see the DB console down and looking into the emoms.trc file below errors intermittently in our Oracle 11gR2 RAC (2 node) production database (Redhat Linux 5): * * * [XMLLoader0] ERROR eml.XMLLoader run.1258 - Fatal error during Loader initialization. Shutting down OMS: ORA-00257: archiver error. Connect internal only, until freed.* * * *java.sql.SQLException: ORA-00257: archiver error. Connect internal only, until freed.* I would like to know why OMS is down? Why the ORA-00257 error causes the OMS to be down? Thank you, S -- //www.freelists.org/webpage/oracle-l
