Hello Expert.
I had changed the permission folder /u01/app on on my DBaaS
chmod -R a+rwX /u01/app/
Now I lost my connection through ORDS and SQL developer, raised error:
ORDS: ORDS was unable to make a connection to the database. This can occur if the database is unavailable, the maximum number of sessions has been reached or the pool is not correctly configured. The connection pool named: |apex|| had the following error(s): IO Error: Got minus one from a read call, connect lapse 41 ms., Authentication lapse 0 ms.
SQL Developer: Status : Failure -Test failed: IO Error: Got minus one from a read call
Please advise
Regards,
Lutfi
