Normally this works fine!
But today I just discovered that it could not work anymore when it has worked few weeks before.
I was able to reproduce the problem on the standby and decided to convert it to snapshot standby to see if it works.
–> Yes it works
So I convert it back to physical standby and I was guessing it’s not working again…
–> But it works now!
So what fixed the issue?
–> Database restart
–> Shared pool
Last software release has changed some package names and also the logon trigger name.
I suspect some objects in the SGA where not referenced anymore.
I think I would have fixed the problem by flushing the shared pool on the standby.
This flush might be integrated as post step for next releases.
