Oracle DB Version 11.2.0.4.15 (SPU Apr 2015) & 16 (SPU May 2015) - Issues?
Is there an issue with either of these patches? I tried applying 11.2.0.4.15 and had issues on my DEV server including unexplainable "ORA-03113 End of communication channel" errors on startup. The instance will not startup correctly and I have to restart the windows service each time after I have performed a shutdown immediate. I attempted to install on a production server to see if I had better luck and received the same ORA-03113 error.
I've since rolled back the production patch and am staying with the previous patch I've had (SPU Oct 2014) until I can figure out what is going on with the security patches.
