1.2.2.6.4 Restrictions

For commands, only "/DIS TRAN", "/DIS PGM" and "/DIS USER" are supported. Once these commands are issued by CMD API, related title segment will be returned through the I/O area, which describes the meaning of each field in subsequent segments.

  • "/DISP TRAN"

    Transaction-related information that can be retrieved in Tuxedo is returned in I/O area. For "/DISP TRAN tranname". The Returned segment title is (excluding the llzz part): 

    T70 TRAN CLS ENQCT QCT LCT PLCT CP NP LP SEGSZ SEGNO PARLM RC

    If "tranname" represents a persistent transaction, only TRAN, CLS, and QCT are supported and will have value in returned segment for GCMD. If "tranname" represents a non persistent transaction, only TRAN, CLS are supported and will have value in returned segment for GCMD.

    For "/DISP TRAN tranname QCNT", returned segment is (excluding the llzz part):

    T70 TRAN GBLQCT. Only TRAN is supported, GBLQCT will be always N/A in returned segment for GCMD.

    Fields length description is as following:
    • TRAN: The name of the transaction, 8 bytes.
    • CLS: The class of the transaction, 3 bytes.
    • ENQCT: Not supported, 5 bytes
    • QCT: The left message count(queue count ) in queue of the transaction, 5 bytes.

    Note:

    The queue count may be accurate and reliable only if the following criteria are matched:
    • The tranname is only handled by the current Tuxedo ART for IMS server.
    • The DISPLAY TRAN is issued after a CHKP without an IOAREA.

    All non supported fields will be filled with N/A in returned segment for GCMD. Every filed is separated with one blank space.

  • "/DISP user

    user related information that can be retrieved in Tuxedo is returned. Returned segment is (excluding the llzz part): CUR_USER CUR_TRAN

  • "/DISP PGM

    program related information that can be retrieved in Tuxedo is returned. Returned segment is (excluding the llzz part): CUR_PGM CUR_TRAN

Note:

Currently, we ignore all other parameters in above three commands. If other commands than above three supported ones are issued by "CMD" call, we return success status without any response segment.
