Hi Sandra, You probably already use this, but just in case you don't: *ORA-600/ORA-7445/ORA-700 Error Look-up Tool (Doc ID 153788.1)* Anyway, the standard practice I follow for these errors is I use the look-up tool, and do a general MOS search. If nothing fruitful comes up, I open an SR with Oracle, send them the pertinent trace files, and let them handle it. I also agree with what the other Lister said regarding 11.2.0.0.
