Trigger on x$dbgalertext to get ORA- notifications

edited Jun 27, 2018 5:02AM in Database Administration (MOSC) 1 commentAnswered

Hello,

I had the idea to create a trigger in x$dbgalertext in sys schema, in order to get notifications for logged ORA-  errors that are critical for the DB, such as ORA-04030 or ORA-04031.

This trigger would run a stored  shared library that could possibly raise an alarm on a GUI.

The thing is that Oracle does not allow the creation of a trigger in sys schema.

Is there a way to force this?

would it be a big performance issue for the dictionary if so?

If yes, is it possible that i force Oracle to write the alert info in an identical table in another schema?
