The ORA-00017 session requested to set trace event
Description:
The ORA-00017 error in Oracle Database indicates that a session has requested to set a trace event, but the requested event is either not recognized or not allowed.
Cause:
This error is caused when a user or session attempts to set a trace event that either doesn’t exist or is not permitted for the current user.
Solution:
To resolve the ORA-00017 error, consider the following steps:
Check Trace Event:
Verify that the specified trace event code is valid and recognized by Oracle.
Ensure that the user has the necessary privileges to set the particular trace event.
Review user privileges.
Ensure that the user attempting to set the trace event has the required privileges.
Users might need specific privileges, like ALTER SESSION, to set certain trace events.
Avoid unsupported events.
Check the Oracle documentation for supported trace events and their syntax.
Avoid using trace events that are not supported or deprecated in the Oracle version you are using.
Example for ORA-00017 Session requested
Attempting to set an unsupported or invalid trace event:
To Attempt to set a trace event that may not exist or is not allowed
ALTER SESSION SET EVENTS ‘10046 TRACE NAME CONTEXT FOREVER, LEVEL 10’;
To resolve this, ensure that the specified trace event (‘10046’ in this case) is valid and that the user executing the statement has the necessary privileges.
To check for a valid trace event with proper privileges
ALTER SESSION SET EVENTS ‘10046 TRACE NAME CONTEXT FOREVER, LEVEL 6’;
By verifying the trace event, user privileges, and using supported events, you can resolve the ORA-00017 error associated with setting trace events in Oracle Database.
