Restoring the Side Information (SI) data set

About this task

To restore the SI data set:
  1. Stop HCL Workload Automation for Z.
  2. Allocate a new SI data set.
  3. Copy the backup data set to the SI data set.
  4. If you allocated the data set with a new name, update all JCL (ddname EQQSIDS) to reference the new SI data set.
  5. Start HCL Workload Automation for Z.
  6. Enter the ETT dialog and verify that ETT criteria are correctly defined. Reapply all changes made since the SI backup was created.
Note:
  • It is recommended that you back up the EQQSIDS data set while the controller is down. If the EQQSIDS data set is backed up while the controller is active, some SI updates might be lost because of LSR buffering.
  • The EQQSIDS data set cannot be backed up if a CP backup is in progress, because of ongoing LSR buffer delete and allocate phase.
  • A backup of the EQQSIDS data set taken after the completion of a CP backup, contains any SI update made prior to the start of the CP backup; any following backup needs to be manually reapplied by the user.
