End Watch (QSCEWCH) API

The End Watch (QSCEWCH) API ends a watch session that was started by a STRWCH (Start Watch) command or by the Start Watch (QSCSWCH) API. Watch sessions started by trace commands (STRTRC, TRCINT, TRCCNN, STRCMNTRC, TRCTCPAPP) will be ended but the associated trace will remain active.

Note: A watch session can be ended from the same job that issued the start function or from a different job.

Authorities and Locks

Authority to use the API

To use this API, you must have service (*SERVICE) special authority or must be authorized to the Service watch function of the IBM i through System i™ Navigator's Application Administration support. The Change Function Usage (CHGFCNUSG) command, with a function ID of QIBM_SERVICE_WATCH, can also be used to change the list of users that are allowed to start and end watch operations.

Authority to watch session

If ending a watch session that is watching for a message within a job log, the issuer of the API must be running under a user profile which is the same as the job user identity of the job being watched, or the issuer of the API must be running under a user profile which has job control (*JOBCTL) special authority. Job control (*JOBCTL) special authority is also required when ending a session where jobs with a generic user name are being watched.

If you end a watch session that was started with *ALL for the watch job name or with a generic user name, you must have *ALLOBJ special authority or must be authorized to the Watch Any Job function of the IBM i through System i Navigator's Application Administration support. The Change Function Usage (CHGFCNUSG) command, with a function ID of QIBM_WATCH_ANY_JOB, can also be used to change the list of users that are allowed to start and end watch operations.

Required Parameter Group

Session ID

INPUT; CHAR(10)

The session identifier for the watch to be ended. This name must match the session identifier of a watch that had been previously started and is still active. You can use these special values for this parameter:

*PRV	The watch session most recently started by the same user who is running this API will be ended. For example, if the job running the API is running under user profile BOB, the last watch session started under user profile BOB is ended.
*ALL	All active watch sessions are to be ended.
generic-name	The generic watch session(s) to be ended. A generic name is a character string of one or more characters followed by an asterisk (*); for example, ABC*. The asterisk substitutes for any valid characters. A generic name specifies all sessions with identifiers that begin with the generic prefix that are to be ended.

Error code

I/O; CHAR(*)

The structure in which to return error information. For the format of the structure, see Error code parameter.
