set role

Trying to get autotrace out of SQL Developer and getting error message.

Failed to access V$MYSTAT.

Please obtain read catalog privilege

from your database administrator:

grant SELECT_CATALOG_ROLE to RAFU

grant SELECT ANY DICTIONARY toRAFU

NOTE: you need to reconnect your current session

in order for the settings change to have an effect

Granted the privileges. I guess less would be enough. Weird note. Why do I need to reconnect the session? There exists SET ROLE command.

SET ROLE ALL;

That does the job. No reconnect needed.
