Issue:

I have an odd problem that I can't seem to understand what is causing it.

I am using a TPX and occasionally I will get the following message after entering a command within Netview:

TCX20003 UNABLE TO ESTABLISH SESSION - PROCESS FAILED WITH SENSE 00002022  

 

The only message I see in the log is:

TPXL0050 01/10/18.010 09:30:50.16 LOSTERM EXIT ENTERED FOR SESSION TCX20003                 

        SB: 1A712188, REASON 20, UNCONDITIONAL TERMINATION

                               EVENT STORAGE PURGED

Environment:
CA TPX for z/OS
Cause:

All information points to this being a problem with Omegamon ETE rather than TPX interfering with the Netview session. 

Previous reports have been noted where Omegamon ETE intercepts the exception response, converts it into a definite response and does not block the next response. 

 

 

Resolution:

Contact your group that manages Netview and/or Omegamon ETE.

Definite response unit failures in VTAM, DB2, and CICS

Definite response unit failures can be apparent in a number of products that use ETE services, and product-unique situations and error codes are produced:

...

--- Intermittent VTAM SENSE 00002022 is found in the SYSLOG. This error usually indicates that required maintenance has not been applied. Check the support pages to ensure that the most recent maintenance has been applied and that the PARM=',NFNDFC=YES' is being used on startup.

 

To resolve these types of issues, a new keyword parameter (NFNDFC) was created to enable ETE users to configure ETE to control whether or not the ETE subsystem forces definite response for non-data flow control RUs. The default is NFNDFC=NO. See “Step 2: Customize the ETE startup JCL” on page 7 for more information.

Refer to “Step 2: Customize the ETE startup JCL” on page 7 for information about how to code this parm statement and for other positional and keyword parameters for the ETE product.

OMEGAMON and IBM Tivoli Management Services on z/OS 

Version 6.2.0 

End-to-End Response Time Feature 

Reference 

----------------------- 

Chapter 2. Understanding end-to-end response time 

ETE measures end-to-end response time for applications that use either definite response protocol or exception response protocol. 

End-to-end response time is the elapsed time between the moment that a user presses a key (Enter, F1 through F24, PA1, PA2, PA3, or Clear) and the moment that a response is received at the terminal. For example, if you start a stopwatch when a user presses Enter and stop it when the terminal receives the application's first response to the user's request, the stopwatch shows the end-to-end response time for that request. 

To measure end-to-end response time, ETE places itself inside one of the VTAM SNA layers. In this location ETE can time all SNA traffic that flows through VTAM. End-to-end response time measurement requires that VTAM internal trace with the PIU option is active. The measurement is started automatically when ETE is activated.

Chapter 5. Customizing ETE to work with a multi-session manager 

...

If you want to run ETE with IBM Tivoli NetView® Performance Monitor, there are special operational considerations when running concurrent ETEs and the IBM Tivoli NetView Performance Monitor (NPM) product.
