Error description

  • Customer is converting TCPIPSERVICE definitions to make use
    of AT-TLS by coding SSL(ATTLSAWARE).  DFHWB0730 is issued when
    trying to make use of the new configuration.  The problem stems
    from CICS determining the connection is not secure. In this
    instance SECURE_CONNECTION(NO) is being returned from a DFHSOIS
    INQUIRE which indicates there is a problem.  The connection was
    not marked as secure because the ATTLS_SECURE bit is not turned
    on.  In this instance the socket's SSL related block is empty
    except for the eyecatcher.  No information has been recorded.
       Earlier trace information contained an SO 0CAB exception
    trace entry indicating the SIOCTTLSCTL call made by CICS had
    failed with a return code of 120 (EINTR).  This is the call
    made by CICS to AT-TLS to determine the state of the
    connection.  The call has failed unexpectedly, but CICS has
    continued anyway.  Any future processing that requires any
    TLS state information will not work correctly

    * PROBLEM DESCRIPTION: CICS issues DFHWB0730 or DFHWB0367 when *
    *                      a web client attempted to connect to    *
    *                      a CICS region secured by AT-TLS.        *
    ****************************************************************
    A connection is made to a CICS region which has an ATTLSAWARE
    TCPIPSERVICE.  The socket listener task (CSOL) makes a BPXIOCTL
    call to obtain information relating to the state of the AT-TLS
    connection.  This call fails due to an interrupt and EINTR (120)
    is returned.  Processing continues without any AT-TLS
    information being recorded.
    
    A CWXN task gets attached to process the request.  This task may
    incorrectly issue message DFHWB0730 or DFHWB0367 due to the
    connection appearing to not be secured by AT-TLS.

Problem conclusion

  • DFHSOLS has been changed so that if the BPXIOCTL call made for
    an ATTLSAWARE TCPIPSERVICE fails with an EINTR response, the
    call is retried.
