Error description

  • A CF structure fails to recover with following messages :
    CSQE101I CSQ1 CSQERCFS Unable to backup or recover structure
    CF1,structure in use
    CSQ9023E CSQ1 CSQERCFS ' RECOVER CFSTRUCT' ABNORMAL COMPLETION

Local fix

  • Restart the queue manager that attempted to recover the CF
    structure and is still connected to the structure. Then issue
    the RECOVER CFSTRUCT command for the structure on any queue
    manager in the QSG.

    ****************************************************************
    When auto recovery starts for a CF structure, CSQERCFT stores
    the address of the STRB for the structure being recovered
    before connecting to the structure. In some cases, such as
    when a previous recovery attempt has failed and auto recovery
    has been rescheduled for the structure, this STRB can be freed,
    and possibly reallocated for use by another structure, before
    it is used by CSQERCFT to locate the structure's BRCB. This can
    cause a failure to copy the BRCB address for the structure into
    the EUWH BRCB array, causing the structure to be excluded from
    the rest of recovery processing, including disconnecting from
    the structure at the end of recovery. The queue manager
    therefore remains connected to the structure and the structure
    remains in INRECOVER state.
    

Problem conclusion

  • CSQERCFT has been updated to ensure that a valid STRB address
    is used for each structure being recovered.
