Error description

• An abend occurred with the following title:
  DSN ,ABND=04E-00C90101,U=xxxxxxx ,M=N
   ,C=121.LOCN=::xx.xx.xx.xxx     ,LOC=DSNIDM  .DSNOGLOB:51F7
                                                                 .
  Db2 code checked if a zEDC device was available to inflate LOB
  data, and received back that it was, so set a flag to indicate
  software inflation was not being used.
  This was via the FPZ4ABC service .
  However when the service request was made, the zEDC cards had
  been deactivated and rc04 rsn2000 was returned to Db2.
  The reason 2000 indicates: 'No zEDC devices are available.
  Inflate is completed in software when hardware is not available'
                                                                 .
  The decompression itself was successful.
  However Db2 had already set the flag to indicate software
  inflation was not being used and this then tripped the abend as
  Db2 thought the inflate hadn't been successful, when it was.

  ****************************************************************
  An ABEND04E RC00C90101 at DSNOGLOB ERQUAL51F7 might occur when
  fetching a compressed LOB column.
  
  The reason for the abend is that Db2 fails to recognize the
  reason code indicating that the LOB has been inflated using
  software. As a result, the reported intentional abend is
  generated.

Problem conclusion

• Db2 is corrected to recognize the reason code for software
  inflate to avoid the abend.
