Delete inactive shipped terminal definitions.
The PERFORM DELETSHIPPED command causes immediate invocation of the CICS mechanism for deleting inactive shipped terminal definitions. It does not reset the interval at which this mechanism is normally invoked; that is, it does not affect the time remaining until the next automatic invocation.
A shipped definition is inactive if the terminal has not been used locally for a specified period of time and no task is waiting to be attached which requires the terminal. You can determine the length of time a shipped terminal must remain unused to be eligible for deletion and the interval at which CICS checks for such terminals with the INQUIRE DELETSHIPPED command, and you can set these values with the SET DELETSHIPPED command. For more information about shipped definitions, see the CICS® Intercommunication Guide and the CICS Resource Definition Guide.
