Tasks performed during New Day Process

CONTROL-M processes execute as background processes on the server computer and remain active at all times except during NDP. Once a day, at the time specified by the CONTROL-M system parameter Day Time (starting time of working day), CONTROL-M starts the New Day Procedure (formerly known as the “General Daily procedure”).

The New Day procedure performs automatic functions that start a new day under CONTROL-M. This procedure is used as a master scheduler for all CONTROL-M

The following actions were performed during NDP till v6.2.01, on later versions these were disabled and a new utility can be executed as a batch job during the day to perform the cleanup

-> Agents cleanup

-> Statistics cleanup

The New Day Procedure performs the following sequence of operations:

  1. A new Odate (CONTROL-M date) is calculated (based on the system date and CONTROL-M system parameter Day Time).

  2. A partial cleanup of the CONTROL-M/Server log is performed, based on system parameter Maximum Days Retained By CONTROL-M Log. 

  3. A partial cleanup of job SYSOUT directories on agent computers is performed, based on system parameter Maximum Days to Retain Sysout Files.

  4. A selective cleanup of the Active Jobs file is performed. Jobs that have already executed and ended OK, and jobs whose parameter Max Wait has been exceeded (and are not Held), are erased from the Active Jobs file.

  5. A partial cleanup of the statistics in the CONTROL-M/Server database is performed. For each job, CONTROL-M retains statistical information regarding the last 20 successful executions. This value can be changed by defining the RUNINF_PURGE_LIMIT parameter in the CONTROL-M config.dat file. CONTROL-M must be shut down and restarted for this change to take effect.

  6. A selective cleanup of prerequisite conditions is performed. Prerequisite conditions are deleted if their date reference (month and day) is equal to the new CONTROL-M date +1 (tomorrow). This prevents jobs from being triggered by prerequisite conditions remaining from the previous year.

  7. Job orders are placed in the Active Jobs file according to job processing parameters contained in Scheduling tables (assigned to User Daily “SYSTEM”). These job orders can include the submission of User Daily jobs.

  8. CONTROL-M begins downloading the new Active Jobs file to the CONTROL-M Configuration Manager. During download, CONTROL-M processes are suspended.
