Processing steps:
1. The NETVIEW stage invokes the MVS command and places the corresponding
response message, in this case an MLWTO, in the pipeline.
2. The CORRWAIT stage allows 5 seconds for each message to return from MVS.
CORRWAIT must be used when sending commands to other applications, such
as VTAM or MVS, to allow enough time for a response to return.
3. The LOGTO stage reads the MLWTO and writes it to the NetView log and the
system log.
Note: There is no output to the screen from this pipeline other than the echo of
the PIPE command. The results of the command appear in the system
log twice because both MVS and the LOGTO pipe stage have logged the
message.
Interfacing with Other Applications: NETVIEW, VTAM
290 Programming: Pipes
Two useful device drivers, VTAM and NETVIEW, can be used to invoke VTAM
and NetView commands respectively. Responses from these commands are inserted
into the pipeline for manipulation by subsequent steps. From there, you can use
another device driver to put the data wherever you need it.
Running a NetView Command: NETVIEW
Use the NETVIEW stage to run NetView commands (local or cross-domain) and
MVS or local VTAM commands with the RMTCMD command. The resulting
messages are placed in the pipe.
Note: To issue MVS commands successfully in a pipeline, use extended multiple
console support (EMCS) consoles.
Example 1: Issuing an MVS Command
This example shows how to use the NETVIEW stage to run an MVS command:
