Error description

  • When an ECI request with a 32767 byte COMMAREA is sent to an
    IPIC connected CICS server, return code -1
    ECI_ERR_INVALID_DATA_LENGTH is received.
    

Local fix

  • Use 32766 byte COMMAREAs or IPIC channels and containers
    support.

    * RECOMMENDATION:                                              *
    ****************************************************************
    When sending ECI requests to IPIC connected CICS servers, CICS
    TG was incorrectly restricting the maximum COMMAREA length to
    32766 bytes. The maximum usable size of a COMMAREA when using
    the IPIC protocol is 32767 bytes.
    

Problem conclusion

  • CICS TG has been changed to allow a maximum COMMAREA length of
    32767 bytes to be flowed over IPIC connections. ECI requests
    specifying COMMAREAs longer than 32767 bytes will continue to
    receive ECI_ERR_INVALID_DATA_LENGTH. This change does not
    affect non-IPIC protocols.
