USER2 TCP2
Figure 14. TSO Command Flow
Figure 14 shows an example execution of a TSO command. Within a pipeline a
NETSTAT command is duplicated using the DUP stage. Multiple NETSTAT
commands become the primary input stream to the TSO command. From
elsewhere in the pipeline, a secondary input stream is connected to the TSO stage.
This secondary input stream contains records with the TSO user ID followed by a
TSO server job member name.
The TSO stage sends the NETSTAT command to all TSO server jobs on the
secondary input stream. Responses are returned from TSO to the CORRWAIT stage
following the TSO stage.
Stream Type Number Supported
Input 2
Output 2
Termination Conditions
TSO terminates when the primary input stream and the primary output stream are
disconnected. If followed by CORRWAIT, CORRWAIT automatically ends when
the TSO command is completed and the response has been received.
