The errors started immediately after the installation of the patch and stop if I roll the patch back. End users are getting ORA-03113 End of Communication channels.
I've logged a SR but the analysts say they cannot reproduce the problem and sent me a document on Troubleshoot the TNS-12537, which I actually had gone through before logging the SR. There is nothing in the troubleshooting guide that applies.
