The Registry Job Shell is designed to provide minimal command line output, with actions instead recorded in tables that can be viewed via the web interface. Currently, only CO Administrators may view Registry job history.
High level job status is maintained in the cm_co_jobs table, including status about the job when it is queued, started, and finished. Specific transaction or task status is maintained in the cm_co_job_history_records table, and these records may be linked to a CO Person or OrgIdentity record. These records may be viewed from the appropriate person canvas, for authorized viewers.
It is up to each job type to determine what sort of detailed records to maintain.
