Debugging NetView Pipelines Displaying Return Codes 350 Programming: Pipes PIPE (NAME SAMP) | (DEBUG) < MYFILE | (DEBUG) STRIP TRAILING / / | (DEBUG) JOINCONT TRAILING /$/ | (DEBUG) CONSOLE For details on the output produced by DEBUG 1, see “DEBUG Stage Option” on page 348. Clogged Pipeline Details: When you receive message BNH155E indicating that a complex pipeline is clogged, it might be difficult to determine the cause of the clog. The DEBUG 2 pipeline option generates additional debugging information when BNH155E is issued. For example, the following pipeline will clog: /* REXX Example */ ’PIPE (NAME CLOGGER END \ DEBUG 2)’, ’|
Additional Troubleshooting Tips Debugging NetView Pipelines If you are not getting the output you expect from your pipeline, check for these possible causes: v The HOLE stage is discarding all pipeline messages. v The CORRWAIT stage is not used following a command-executing stage, such as NETVIEW or VTAM, causing asynchronous messages to be lost because no time interval is allowed for their return. v Pipeline messages are not generated by the stage preceding the NETVIEW stage; therefore, the command issued by the NETVIEW stage is not triggered to execute. v In a PIPE-within-a-PIPE structure, the CORRWAIT stage is not used, or is used incorrectly, following the CONSOLE stage, which is used to return messages from a remote pipeline to a local pipeline. The function of the CORRWAIT in the local pipeline is to wait for messages to travel from the remote to the local NetView. The CORRWAIT stage must be used. If it is already being used increase the interval. In addition, you might want to add the MOE option to check for a timeout. There must be enough time allowed for the messages to travel from the remote to the local NetView. v You have multiple pipelines in a command list or a PIPE-within-a-PIPE structure, but you have not used the NAME option to distinguish them.
