IMSPLEX data sharing and XRF considerations

IMSPLEX Data Sharing Considerations

Regardless of the number of LPARS that are involved, only one IMS definition is required in an IMS data sharing environment where all databases are shared by multiple IMS subsystems.

In an IMS data sharing environment where only a subset of databases is shared, an IMS definition must be created for each IMS subsystem with nonshared databases to be audited.

XRF Considerations

Only one IMS definition is required in an IMS XRF environment. IBM Security Guardium S-TAP for IMS on z/OS is not sensitive to which XRF partner is currently active. The product continues to produce audit data in the event of an XRF ACTIVE/BACKUP switch.
