    Is there a reason that you haven't applied any patchsets to your database? You're running the very first 11.2 release. Do you have a support contract? ORA-00600 and ORA-00745 errors are internal Oracle errors. Normally, you'd use the Metalink search tools to see whether the ORA-00600 and ORA-00745 error lookup tools find anything useful or whether you need to log a support request. Mar 10, 2014 at 17:17
