Current plan (EQQCPnDS)

The current plan (CP) is created from the LTP, AD, RD, and WS databases. The CP consists of VSAM files created by any of the following daily planning batch programs:
  • Plan next period. This creates the initial CP and thereafter extends the CP by modifying it with new information from LTP, AD, RD, WS, and the old CP (if available).
  • Replan current period. This reorganizes the CP with new information from the databases.

The CP is also updated dynamically by the job-tracking functions, the MODIFY CURRENT PLAN dialog, the program interface (PIF), the application programming interface (API), Dynamic Workload Console, OCL, BCIT, and by events created from RODM notifications.

HCL Workload Automation for Z uses these VSAM data sets when creating or maintaining the current plan:
  • The primary current-plan data set, DD name EQQCP1DS.
  • The alternate current-plan data set, DD name EQQCP2DS.
  • The new current plan (NCP) data set, DD name EQQNCPDS.
  • The new current plan extension (NCX) data set, DD name EQQNCXDS.
  • The current plan extension (CX) data set, DD name EQQCXDS.
  • The primary "extended data" data set EQQXD1DS
  • The alternate "extended data" data set EQQXD2DS
  • The new "extended data" data set EQQNXDDS
The "extended data" data sets are used in the same ways as the current plan VSAM files.

When the CP is created, extended, or modified, it is held in the new current-plan data sets, NCP and NCX. The CP turnover process copies the NCP into one of CP1 or CP2 (whichever is inactive), and then this data set becomes the active CP. The NCX is copied to the CX data set, and the CX data set is then copied to a data space managed by the controller.

The primary and alternate CP data sets (CP1 and CP2), are used in a flip-flop manner; that is, HCL Workload Automation for Z copies the active CP to the inactive data set, and then uses this newly copied data set as the active CP. The active data set is called the CP logical file.

Updates to the CX file are made in the data space. During the current plan backup process, the data space is refreshed to DASD.
