PK50997: SUPPORT OF IMS V10 CHANGES FOR OLR '2930'X LOG RECORD

APAR status

• Closed as program error.

Error description

• IMS OLR development made significant changes to the format of
  the OLR '2930'x log record, and DRF needs to add the code to
  support the changes.

  * PROBLEM DESCRIPTION: This APAR addresses four problems.      *
  *                      1.                                      *
  *                      DRF does not pick up the new IMS        *

  *                      When OLR allocates the output data      *
  *                      sets, the space allocation is always    *
  *                      done in blocks and not in the same      *
  *                      units as the input data sets.           *
  *                                                              *

  For the problem one:
  The 2930 mapping in DRF does not match the mapping of IMS.
  OLR is not fully supported by DRF.
  
  For the problem two:
  When an OLR input data set is allocated in tracks or cylinders,
  the existing logic in FRXIOCR0 converts the primary and
  secondary amounts to blocks, and the output data sets space
  allocation is done in blocks to provide device independence.
  
  For the problem three:
  OLR log records are skipped during the log processing.
  
  For the problem four:
  track flag is on when the unit of space size is block.
  

Problem conclusion

• AIDS: RIDS/UTIL RIDS/DBS DBS/UTIL
   GEN:
  KEYWORDS:
  
  *** END IMS KEYWORDS ***
  FRXOLRA has been modified to match IMS mapping of 2930 records.
  
  FRXIOCR0, FRXIOCC0, FRXIOCD0, FRXDDCR0, FRXDDCC0 and FRXDDCD
  have been modified to allocate the output data sets in the
  same units as the input data sets, specifically, if the  input
  data sets are allocated in tracks or cylinders, the output
  data sets will also be allocated in tracks or cylinders.
  
  FRXRBUF0 and FRXIICC have been modified to fix the errors of
  skipping the OLR records.
  
  FRXDDCD0 has been modified to fix the calculation problem for
  the output space unit size.
  
  FRXDDCP0,FRXDDDF0,FRXDDDL0,FRXIIOM0,FRXIOCP0,FRXIODF0,FRXIODL0,
  FRXIOSM0 and FRXIVSM0 have been recompiled due to FRXOLRA and
  FRXIICC changes.
