IBM Tivoli NetView for z/OS Programming: Pipes - IBM notice

NetView Pipelines Device Drivers
294 Programming: Pipes
Processing steps:
1. The VTAM stage invokes the incorrect DISPLAY command and returns error
messages DSI071I and IST191I, to the pipe. The MOE option generates the
DW0369I message.
2. The CORRWAIT stage allows 5 seconds for each message to return from
VTAM. CORRWAIT must be used when sending commands to other
applications, such as VTAM or MVS, or to another NetView system to allow
enough time for a response to return.
3. The CONSOLE stage reads the messages and displays them.
Example 3: Running a VTAM Command in a Remote Domain
This example shows how to use the VTAM stage to issue the D NET, CDRMS
command in a remote domain and return the results to the screen at the local
domain:
PIPE NETVIEW RMTCMD LU=CNM01,
PIPE (STAGESEP %) VTAM D NET,CDRMS
% CORRWAIT 10
% CONSOLE
| CORRWAIT 20
| CONSOLE
Output from the pipeline follows:
NCCF NETVIEW CNM19 OPER6 04/29/10 14:35:00
* CNM19 PIPE NETVIEW RMTCMD LU=CNM01, PIPE (STAGESEP %) VTAM D NET,CDRMS

Processing steps:
1. The outer pipe starts running.
2. The NETVIEW stage issues the RMTCMD to send the inner PIPE command to
the remote domain to run.
3. The inner pipe starts running.
4. The inner pipe runs at the remote domain. Within it, the VTAM stage issues
the DISPLAY command and resulting messages are returned to the inner pipe.
(The messages are not displayed at the remote domain.)
5. The CORRWAIT stage waits 10 seconds for each message to return to the
inner pipeline from the VTAM stage.
6. The CONSOLE stage reads the messages and returns them to the outer pipe.
They are NOT displayed on the screen at the remote location.
7. The inner pipe terminates.
