  * PROBLEM DESCRIPTION: z/OS health checker message DFHH0951    *
  *                      needs to emphasise that CICS XRF        *

  ****************************************************************
  Message DFHH0951 reports that CICS has been started with XRF=YES
  defined. XRF support has been stablised for many years and will
  be withdrawn. The message should be made clearer regarding this.
  

Problem conclusion

• CICS has been changed to issue message DFHH0951 as an exception
  rather than a warning message.
  
  The message definition in the "CICS Messages - part 3 DFHSHnnnn
  to DFHZNnnnn, and DFHHnnnn messages" manual will be updated as
  follows, in Chapter 37. IBM Health Checker for z/OS messages
  related to CICS (DFHHnnnn messages):
  
  DFHH0951 XRF is in use.
  Explanation:
  CICS is running with XRF=YES specified in the SIT. The extended
  recovery facility (XRF) support is stabilized. It is IBM's
  intention to remove support for XRF=YES in any future releases
  of CICS. The Health checker is now reporting this setting as an
  error to help draw attention to this fact.
  System action:
  The system continues processing.
  Operator response:
  Report this error to the system programmer.
  System programmer response:
  Actively review the use of XRF in your CICS environment. You
  must move to 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. For more information about
  stabilized technologies, capabilities, and functions, see
  Stabilization notices and discontinued functions.
