Error description

• Dump Title: OMEGAMON II FOR DB2: COMPID=5655OPE00, JOB=CANSO2  ,
  LMOD=#UNKNOWN#L, CSECT=SNP$0000, OFFSET=  0102
  ABENDDC2 rsn0040 rsn71004021 issued by IAXV6+BFE following
  a IARV64 SHAREMEMOBJ issued by KO2CDFSA+984 (at PK76938 level).
  KO2CDFSA was accessing the RQA, a DB2 control block that in V910
  DB2, can be acquired either in shared memory above the bar or in
  common storage below the bar.  When the shared storage above the
  bar is used, storage addresses are 64 bit and accessed by the
  IARV64 MACRO.  However, when the storage is below the bar and
  the IARV64 MACRO is issued to access it, the ABENDDC2 rc0040
  will occcur.  Omegamon should first check for the location of
  storage prior to its access to avoid this ABEND.

  This error will only occur when z/OS DB2 V910 is used.
