Duration ST01 can be activated


We recently made a temporary role change for one of our end user. The user's manager approved the change subject to switching on the ST01 trace for as long as the new role is active - which is for a month. This is for audit records.

My question is - how long can ST01 trace be activated on a single user? Is a month normal or too long? And will the trace be good enough?

Thank you.
