PI87887: REMOVE RESTRICTION OF MVSNAME AS SECOND HIGH LEVEL QUALIFIER (HLQ) FOR COMMIT, UNCOMMIT AND NOTPARMS DATASETS

Obtain the fix for this APAR.

APAR status

• Closed as new function.

Error description

• When a client has many IMS systems ( >100 ) both native and SQ,
  in order to guarantee business continuity they have to be able
  to move IMS across z/OS and LPAR's in case of z/OS failure, LPAR
  failure or even for workload balancing (close an LPAR and move
  IMS subsystems and QCF onto other z/OS systems).
  Under this basic requirement IMS QCF is implemented, but due to
  strict naming conventions for COMMIT, UNCOMMIT and NOTPARMS
  datasets (where MVSNAME is a must), clients are not able to
  respect it. Currently, IMS QCF requires the naming conventions
  to be as follows: ovflhlq.MVSNAME.IMSID.NOTPARMS
                    ovflhlq.MVSNAME.IMSID.COMMIT
                    ovflhlq.MVSNAME.IMSID.UNCOMMIT
  whereas MVSNAME is the second level HLQ.
  
  This restriction doesn't allow for the movement of IMS's and
  QCF's across a z/OS LPAR.  This enhancement will remove
  MVSNAME as an HLQ restriction for the dataset allocation.
  
  This enhancement is based off of RFE 81642.

  * PROBLEM DESCRIPTION: If customer has more IMS's systems      *
  *                      (both native and SQ), In order to       *
  *                      guarantee business continuity they are  *
  *                      now able to move IMS across z/OS and    *

  ****************************************************************
  * RECOMMENDATION: Install the APAR, and set the preferences    *
  *                 for NOTPARMS, COMMIT and UNCOMMIT data set   *
  *                 names. Create the common data sets, if you   *
  *                 choose that they do not have the MVSNAME     *
  *                 and/or IMSID as middle level qualifiers.     *
  ****************************************************************
  Allow for COMMIT, UNCOMMIT, and NOTPARMS data sets to not

Problem conclusion

Temporary fix

Comments

• Install the APAR, set the preferences and create the new data
  sets, that do not have the MVSNAME and/or IMSID as middle level
  qualifiers.
