Problem summary

• ****************************************************************
  * USERS AFFECTED: All CICSPlex SM V5R4M0 and V5R5M0 Users      *
  ****************************************************************
  * PROBLEM DESCRIPTION: Add support into CICS TS 5.4 and 5.5 to *
  *                      support BAS configurations in large     *
  *                      CICSplex environments.                  *
  ****************************************************************
  * RECOMMENDATION: After applying the PTF that resolves         *
  *                 APAR PH19761, all CMASes must be             *
  *                 restarted to pick up the new code. The       *
  *                 restarts need not be performed at the        *
  *                 same time.                                   *
  ****************************************************************
  The CICSPlex SM BAS component should be able to use all
  available BAS data space storage by spreading large resource
  deployment lists for BAS across multiple data spaces instead of
  being constrained to a single data space. This feature will be
  disabled by default in CICS TS 5.4 and CICS TS 5.5 and can be
  enabled by setting the feature toggle
  com.ibm.cics.cpsm.bas.largecicsplex=true in all CMAS regions.
  
  This capability is also available on
  CICS TS 5.6 with APAR PH26781.
  

Problem conclusion

• The CICSPlex SM BAS component has been updated to interact with
  new support in the CHE component for Cache List structures which
  can span across more than one data space.
  
  This feature will be disabled by default in CICS TS 5.4 and
  CICS TS 5.5 and can be enabled by setting the feature toggle
  com.ibm.cics.cpsm.bas.largecicsplex=true in all CMAS regions.
  
  The CICS TS for z/OS for V5.4 and V5.5 Knowledge Center has been
  updated to reflect these changes.
