I thought I was solving an ORA-3113 problem (end-of-file on communication channel) when I was actually solving an ORA-1113 problem (file %s needs media recovery). It was only when I started to write up the experience that I realized that I had solved the wrong problem.
Struck a problem today with Logical Standby due to SYS.AUD$.
Now that Flashback Data Archive is now included in the base 188.8.131.52 license, I had the crazy idea to mix it with Database Editioning.
Today, we did some rough and ready performance tuning of one of our logical standby database instance.
