A session transcript comprises several files.
Within /var/log/ts-shell there is a subdirectory for each user who conducted a terminal session for which a transcript was created.
<vm_guest>_<YY-MM-DD-hhmmss>
where <vm_guest> is
the z/VM® user ID that identifies
the target system and <YY-MM-DD-hhmmss> is
a time stamp that indicates when the session was started.The file with extension .info is a human readable text file. The transcript file without an extension and the file with extension .timing are intended for replaying a session. See the scriptreplay man page for details.
Consider a cron job to purge obsolete transcripts according to your audit policies.
