A trace has already been activated for user & in ST01
Help Document

Diagnosis

The trace can only be activated for one user or group of users on each application server.

Since a trace has already been activated for the specified user in ST01, you cannot activate any of the performance traces (SQL trace, RFC trace, HTTP trace, enqueue trace, buffer trace) on this application server.

Procedure

Wait until the other user deactivates the trace. You can then activate the performance trace and other traces.

You can also activate the trace for all users, or for users whose names match a pattern. In this case, specify the pattern in the usual format.

You can activate the trace for multiple users by choosing the button "Activate Trace with Filter".
