New Day Procedure

The New Day procedure is the primary mechanism used to perform daily maintenance on the Control-M/Tape Media Database and related files. The New Day procedure (job CTTDAY), can be activated automatically by a scheduler (for example, Control-M) at a predefined time each day. It can also be activated manually.

When establishing the New Day procedure for Global Test mode:

• Ensure that the order in which various tasks are performed in the New Day procedure is compatible with the existing tape management system. For example, retention management precedes vault management in CA-1, while vault management precedes retention management in CA-TLMS.

  Two New Day procedure members (CTTDAY and CTTDAYT) are provided with Control-M/Tape, each with an alternate order of procedures. Ensure that the correct one is used at your site.

  Note: If the order of procedures in the Control-M/Tape New Day procedure is different from the order in the other tape management system, it could lead to inconsistencies in retention (reflected in the daily scratch and vaulting reports).

• Determine which functions should be performed during Global Test mode (for example, retention and vault management processing) and which should not be performed (for example, automated tape library management procedures).

  Comment out (//*) the JCL steps that you do not want to run while in Global Test mode (for example, stacking statistics collection). Do not delete these steps. They are used when Control-M/Tape is activated in Global Phased mode and Global Production mode.

• Make sure that utilities called by the New Day procedure are compatible with the existing tape management system (for example, retention is processed in the same way).
• Make sure that compatible report formats are used. Customize Control-M/Tape report formats to match the existing system.

Control-M/Tape maintenance functions should run in parallel with (at the same time as) the maintenance utilities of the existing tape management system at your site. New Day procedure CTTDAY is compatible with most tape management systems. If you are converting from CA-TLMS, run CTTDAYT in the JCL library instead of CTTDAY. In CTTDAYT, the vaulting step precedes the retention step in order to maintain compatibility with CA-TLMS.

The following tasks are performed by the New Day procedure:

• Rule Refresh.
• Retention Management (CTTRTM).
• Vault Management (CTTVTM).
• Gathering Data Set Size Statistics for Stacking (CTTSTK).
• Media Database and Trace File Backup (CTTTRB).

Each of these tasks is described below, with special attention given to issues relevant for Control-M/Tape operations in Global Test mode.
