    z/OS 1.7 provides the SDWA field SDWABEA, which contains the
    address of the last executed branch instruction. CICS does not
    format this information as part of the KE VERBX formatting for
    system dumps. This is a serviceability requirement for diagnosis
    of wild branch problems.

Problem conclusion

  • CICS Kernel domain has been changed to include "Branch Event
    Address: xxxxxxxx" as part of the formatting for its KE VERBX
    data.
      The CICS TS 3.2 Supplementary Data Areas manual
    (GC34-6864-00) will be updated. The KECB description of the TAS
    DSECT will be changed as follows:
      The 3 byte reserved field at offset x'3FD' within TASK_ENTRY
    on page 377 will become:
    (3FD)  CHARACTER   1  TAS_BEA_2  2nd part of SDWABEA
    (3FE)  CHARACTER   2  *          Reserved
    .
      The 3 byte reserved field at offset x'1D' within
    TAS_ERROR_DATA on page 378 will become:
    (1D)   CHARACTER   3  TAS_BEA_1  1st part of SDWABEA
    .
      The CICS TS 3.2 Data Areas manual
    (GC34-6863-00) will be updated as follows:
      The 3 byte reserved field at offset x'4D' within
    KERNEL_ERROR_DATA will become:
    (4D)   CHARACTER   3  CICS_BEA_1  1st part of SDWABEA
    .
      The 3 byte reserved field at offset x'225' within
    KERNEL_ERROR_DATA will become:
    (225)  CHARACTER   1  KERNEL_BEA_2  2nd part of SDWABEA
    (226)  CHARACTER   2  *             Reserved
