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

Chapter 8. Debugging NetView Pipelines
If your pipelines are not functioning, there are several things that you can do to
identify the source of the problem. The pipeline processor examines your pipeline
specification for syntax errors, before attempting to run it. When the processor
finds syntax errors, it displays error messages.
Understanding Error Messages
Online Help
Pipeline error messages do not display the name of a failed stage; instead, error
messages provide the position of the failed stage in the pipeline specification. If
there are multiple syntax errors, the processor displays an error message for the
first syntax error found. When that error is corrected, the processor examines the
specification for any additional syntax errors.
For example, an operator enters:
PIPE NETVIEW CLOSE IMMED | CONSOOOLE
The command contains the two stages, NETVIEW and CONSOLE (which is
misspelled). The pipeline processor finds the syntax error and displays messages to
the console as shown below. Notice that although the DWO362E message does not
name the CONSOLE stage, it does indicate that an error was found in the second
stage specification in the PIPE command, thus pointing to the CONSOLE stage.
NCCF NETVIEW CNM01 OPER6 03/20/10 12:15
* CNM01 PIPE NETVIEW CLOSE IMMED | CONSOOOLE
- CNM01 DWO364E PIPELINE TERMINATED. NO STAGE CONSOOOLE EXISTS.
- CNM01 DWO362E PIPELINE TERMINATED. ERROR IN STAGE 2 IN PIPELINE ’PIPE’.
Note: Stage names inserted with the INTERPRT stage always have a stage number
greater than 10 000. The CLOSE IMMED command did not run because the
pipeline did not start. See “PIPE INTERPRT ” on page 143 for more
information.
To display online help for the pipe command, enter:
HELP PIPE
To display online help for a specific stage, enter:
HELP PIPE stage_name
Where:
stage_name
is any NetView PIPE stage.
See Chapter 2, “Pipeline Stages and Syntax,” on page 19 for a list of stages
supported by the NETVIEW PIPE command.
