OA47340: ABEND002-F7, ABEND0C1, ABEND737-28, ABEND614-24 PROCESSING A ZEDC DATASET

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• All 4 problems (abend002, abend0C1, abend737, abend614) are
  caused by an overlay of the RMR token in one of the access
  methods internal control blocks. An inconsistent compression
  block size causes the token field to get overlaid by in invalid
  scatter/gather list being built. This invalid compression
  blocksize exists within the catalog entry for the dataset.

Local fix

• Copy the dataset with IEBGENER and then use the newly allocated
  copy instead.

  Various abends may be encountered when an invalid physical
  blocksize for a zEDC compressed format data set exists in the
  catalog.
  

Problem conclusion

• New abend reason codes added to attempt to detect this invalid
  condition. Abend 213-FA:During open of a zEDC compressed format
  data set, an invalid physical blocksize (VVRNCISZ) was found in
  the catalog.
  Abend 213-FB:During open of a new zEDC compressed
  format data set, an invalid physical blocksize was derived.
  In addition, an abend 0C1 issued to catch invalid attempt to
  overflow beyond the internal compression array.
  
  An incorrect value will occur if the data set is allocated,
  opened and then closed without writing data when the system
  determines it should be tailoreed or generic.  If the data
  class or PARMLIB default is then changed so that the next
  open determines that the data set should be zEDC compressed,
  a physical blocksize for tailored or generic will exist in the
  catalog and would have been used before this fix.
  The code in OPEN has been changed to correct the physical
  blocksize for a zEDC compressed data set if it if found to
  be incorrect and the data set is empty.
