ORA-30687
session terminated by debugger
Cause
The execution of the session was stopped by the debugger. This can occur because of an explicit request sent by the debugger, or because the debugger disconnected without requesting the ORACLE server to let the session continue to run after the disconnection. It can also occur if the ORACLE server needs to disconnect the debugger at a time when the person controlling the debugger might not expect, such as upon a reset of the related package state or a change of the login user. To prevent continuing the execution using debugger-introduced modifications that might have been intended to be temporary, the ORACLE server needs to fully terminate the session.
Action
This is in response to a debugger request; it is not an error. No action is required.
