Current plan data sets (EQQCPnDS)

The current plan VSAM files are opened and closed many times by IBM Z Workload Scheduler during normal processing. If IBM Z Workload Scheduler is unable to open one of the files, for example if the file is already opened by another job or TSO user, the normal mode manager (NMM), is terminated. The NMM issues message EQQN027E which reports the reason for the unexpected termination. You can issue a MODIFY command to restart the NMM subtask.

It is recommended that you do not access the current plan files from outside the IBM Z Workload Scheduler address space. Backups of current plan information should be taken from the new current plan (EQQNCPDS). Shut down the Z controller address space if full-pack backups are taken of the volumes where the data sets reside.
