Last updated on APRIL 17, 2023

Applies to:

Oracle Database - Standard Edition - Version 12.2.0.1 and later
Information in this document applies to any platform.

If we create a 'after startup on database' trigger with an infinite loop operation as below, we will find the startup session will be hang.

It seems to hang during the open phase because the session only showes information "Database mounted".

Also in alert log, there is no message like ''Completed: ALTER DATABASE OPEN".

We may be counfused if the timing of 'after trigger' starts is after database has been open.
