XRF

Stabilized feature: The Extended Recovery Facility (XRF) in CICS is stabilized. Consider alternative technologies that provide more flexible high-availability solutions for modern workloads. These solutions include the z/OS Automatic Restart Manager (ARM), CICS data sharing, VTAM persistent sessions, and use of the cross-system coupling facility. See also Stabilization notices.

The XRF system initialization parameter specifies whether XRF support is to be included in the CICS® region.

XRF={NO|YES} (active and alternate): If the CICS region is started with the START=STANDBY system initialization parameter specified, the CICS region is the alternate CICS region. If the CICS region is started with the START=AUTO, START=INITIAL or START=COLD system initialization parameter specified, the CICS region is the active CICS region. The active CICS region signs on as such to the CICS availability manager.; If you specify XRF=YES, do not specify a value for the GRNAME system initialization parameter. Any value specified is set to blanks.

Note: Use of GNTRAN option DISCARD is not supported with XRF=YES.
