PK47518: MESSAGE IKJ56225I DUE TO DRF DYNAMIC ALLOCATION OF CA WITH DISP=OLD.

APAR status

• Closed as program error.

Error description

• DRF dynamic allocates the Change Accum file with DISP=OLD.
  This is to prevent any other jobs from attempting to change the
  
  CA in the middle of recovery.We are looking into the possibility
  of a SYSIN parameter to indicate that DISP=SHR is to be used
   instead.

Problem summary

• ****************************************************************
  * USERS AFFECTED: IMS users with IMS Database Recovery         *

  ****************************************************************
  * PROBLEM DESCRIPTION: While running multiple DRF recovery     *
  *                      jobs in parallel, it may be possible    *
  *                      for users to encounter a MSGIKJ56225I   *
  *                      DATA SET ALREADY IN USE, TRY LATER+     *
  *                      and MSGIKJ56225I DATA SET IS ALLOCATED  *
  *                      TO ANOTHER JOB OR USER.                 *
  ****************************************************************
  * RECOMMENDATION: INSTALL CORRECTIVE SERVICE FOR APAR/PTF      *
  ****************************************************************
  While running multiple DRF jobs in parallel it may be possible
  for each job to run into a conflict attempting to access the
  same image copy, log, or change accumulation data set.  This is
  because DRF dynamically allocates each of these input data sets
  with DISP=OLD.  This is to prevent the possibility of a
  different job attempting to update or change the contents of
  the input data sets while they are being used for recovery.
  
  A new option needs to be provided to give the user the
  flexibility to have the input data sets allocated with DISP=SHR.
  

Problem conclusion

• AIDS: RIDS/UTIL RIDS/DBS DBS/UTIL
    DEP: NONE
    GEN:
  
  *** END IMS KEYWORDS ***
  FRXEDRF, FRXEDRF0, FRXEPSS0, FRXEWSP, FRXRVGB, FRXRWSP,
  FRXVWSP, FRXRWCE, and FRXVSTA0 are changed to support a new
  DISPSHR option on a new sysin control statement OPTION.  This
  will be used to override the default DISP=OLD with DISP=SHR
  during input data set dynamic allocation.
  
  FRXIDYN0 and FRXYADY0 are changed to recognize if the user
  specified the DISPSHR option.  If specified then DRF will use
  DISP=SHR for dynamic allocation of input data sets.
  
  The following DOC changes are made:

  Chapter 3 Defining and tailoring the IMS Database Recovery
  Facility environment
  
  A new parameter OPTION and subparameter FCTOPPRCP are added:
    OPTION(<subparameters>)
      An OPTION statement is used to explicitly specify optional
      parameters and overriding default values for your recovery
      environment.
  
      OPTION subparameter syntax
                             --NO---
                             |     |
      >>--OPTION(---DISPSHR(---YES---)-----)--------><
                  |                      |
                  |            --NO---   |
                  |            |     |   |
                  --FCTOPPRCP(---YES---)--
  
      DISPSHR(YES|NO)
        Specifies that the dynamic allocation of IC, log, and CA
        will be with DISP=SHR, otherwise the default setting will
        be DISP=OLD.
        The default setting of DISP=OLD helps ensure that no
        other jobs will attempt to update the contents of your
        input data sets in the middle of the recovery process.
        The DISP=SHR setting will give users the flexibility of
        running multiple jobs in parallel if all that is expected
        by these jobs is READ access.
