ZTStart

Examples of ZTSTART

The ZTSTART command marks the beginning of a logical transaction within a GT.M program. ZTSTART and ZTCOMMIT "fence" transactions (that is, mark the beginning and end). Fenced transactions prevent the MUPIP JOURNAL facility from recovering incomplete transactions. All ZTSTARTs must be matched with ZTCOMMITs before the journal processing facility recognizes the transaction as complete.

The format of the ZTSTART command is:

    ZTS[TART][:tvexpr]
    

For more information on Journaling and transaction fencing, refer to the section on ZTCOMMIT and the "GT.M Journaling" chapter in the GT.M Administration and Operations Guide.
