Planning the DRMODE System Parameter z/OS MVS Setting Up a Sysplex SA23-1399-00 |

The DRMODE system parameter indicates whether the system is being IPL'd as part of a unique disaster recovery scenario and special handling of certain resources are required. Generally, for almost all IPL's, specify:
When a system is being IPL'd following a sysplex failure case,
or specific test, and this single system is being used as the recovery
system to reestablish the resources before restarting work loads,
then specify:
The YES option along with a Y response to Logger confirmation message IXG068D causes System Logger to include DRXRC-type staging data sets in its log data recovery for coupling facility structure-based log streams that had been connected prior to the IPL with the DRMODE=YES option. When this option is specified, it is assumed that the necessary actions had been taken to establish the DASD consistency groups related to the Logger data sets. |
