Error description

  • You are using DB2 V10 and you have some DB2 subsystems that
    are defined as a subgroup of a data-sharing group.  You are
    specifying the subgroup name as the DB2Groupid on the CICS
    DB2CONN to try to get CICS to connect to a member of that
    subgroup.  But the attempt fails with this message:
    .
    DFHDB2047I "The CICS-DB2 Attachment cannot find DB2 group xxxx"
    where xxxx is the subgroup specified in the DB2Groupid .
    .
    Also, in a dump, the following exception trace entry is
    issued:
    .
    AP 3247 D2CO *EXC* SUBSYSTEM_FOUND_WITH_SAME_NAME_AS_REQUESTED_G
    ROUP(DGB2)_BUT_IN_WRONG_GROUP(DB2B) where DGB2 is the requested
    subgroup and DB2B is the data-sharing group .

    * PROBLEM DESCRIPTION: Message DFHDB2047I when using CICS to   *
    *                      connect to a DB2 V10 subgroup.          *

    ****************************************************************
    CICS does not allow the use of DB2 subgrouping provided in DB2
    V10. If a connect to a subgroup is issued, DFHD2CO will not
    check the subgroup name returned in new field EIBSGATT against
    the value in GLB_DB2_GROUP_ID. This results in CICS
    disconnecting from the subgroup and issuing message DFHDB2047I,
    as it only checks whether the group name matches the name
    it connected to, before disconnecting from DB2.

Problem conclusion

  • DFHD2CO has been changed to also check for GLB_DB2_GROUP_ID
    to match the subgroup name of EIBSGATT.
      The CICS TS 4.1 trace entries manual SC34-7013-00 will
    be updated as follows. The CICS-DB2 trace point AP 3237
    on page 282 will be amended to add a new Data Item 6:
    "6       DB2 EIB block"
    The CICS-DB2 trace point AP 3247 on page 283 will be
    amended to add a new Data Item 3:
    "3       Returned Subgroup name"
