New Day Processing: Automated Loading of Rules

Control-M/Tape rules are normally loaded when Control-M/Tape is brought up. A predefined list of rule tables is scanned for rules that should be activated for the current day or date. Rules whose day or date specifications (meaning, basic scheduling criteria) are satisfied are loaded into memory. To ensure that rules to be activated on a specific day are loaded for that day, it is highly recommended that you reload rules each day. Reloading of rules is performed automatically through the Control-M/Tape New Day procedure.

The New Day procedure also performs other tasks that need to be performed each day. This series of maintenance and housekeeping tasks is performed once a day at a specific time (usually the start of the working day). Control-M/Tape does the following through the New Day procedure:

• Reloads Control-M/Tape rules
• Expires unneeded data sets and volumes
• Reassigns volumes to different vaults
• Backs up the Media Database
• Checks the integrity of the Media Database
• Accumulates statistical information on the data sets created yesterday

Other tasks can optionally be added to the New Day procedure. Implementation and modification of the New Day procedure are described in detail in the Control-M/Tape chapter of the INCONTROL for z/OS Administrator Guide.
