PK77437: HSSR ISSUES FABH0661E/FABH0031E FOR VSAM ESDS

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When a VSAM/ESDS data set is still open on an IMS online
  region, HSSR issues ABEND U4013 with the following messages:
   FABH0656I MEDIA MANAGER IS USED TO ACCESS DB: XXXXXXXX
   FABH0661E: RBA REQUEST BEYOND ORIGINAL DATASET LIMITS
              DDNAME=XXXXXXXX
   FABH0031E DDNAME=XXXXXXXX; DATA REQUEST OUTSIDE OF DATASET
             LIMITS
  This problem does not occur when 'HPIO=NO' is specified in the
  HSSROPT data set.
  

Local fix

• Specify "HPIO=NO" in HSSROPT control statement data set.

  When the Media Manager is activated and VSAM ESDS data set is
  still opened on the IMS Online, HSSR issues ABEND U4013 with
  FABH0661E, and FABH0031E messages;
    FABH0656I MEDIA MANAGER IS USED TO ACCESS DB: XXXXXXXX
    FABH0661E: RBA REQUEST BEYOND ORIGINAL DATASET LIMITS DDNAME=
    FABH0031E  DDNAME=xxx; DATA REQUEST OUTSIDE OF DATASET LIMITS
  
  Using the Media Manager for reading VSAM ESDS is one of new
  features of IMS High Performance Unload for z/OS, Version 1
  Release 2.
  When 'HPIO NO' is coded in the HSSROPT data set, the Media
  Manager is not used and this problem does not occur.
  

Problem conclusion

• The FABH511 and FABH661 modules have been modified to obtain
  high-used RBA of ESDS from VSAM shared information (VSI),
  instead of Media Manager MMSHURBA.
