This mode allows you to test Control-M/Tape without affecting the production environment. Global Test mode is activated after the Media Database and Control-M/Tape rules have been created from information extracted from the tape management system being replaced.
In Global Test mode, the existing tape management system manages the production environment (for example, decides whether to accept a tape, protects data sets, issues prompts to the operator, uncatalogs expired data sets). Control-M/Tape updates the Media Database when its decisions match those of the existing tape management system. Control-M/Tape also sends warning messages to the Job log, System log, or Operator console if there is a contradiction between what the existing tape management system is doing and what Control-M/Tape would do if it were in Global Production mode.
In this mode, operators compare reports (for example, scratch reports, vault reports) generated by the existing tape management system to analogous reports produced by Control-M/Tape.
When the two systems’ reports match and Control-M/Tape operates according to your expectations, the next step is to enable Control-M/Tape and the other tape management system to operate simultaneously (in Global Phased mode).
