Does the OPS/MVS API field API.TOKEN contain the thread token value?

You have created an IQL exception using the THREAD-STATS record (Ifcid 148) which will cancel a thread if certain conditions are met.

The option to issue an OPS/MVS API event has been activated, and you are expecting the API.TOKEN field to contain the value for the THREAD-TOKEN field. You want to be able to use this to cancel the thread.

Does the OPS/MVS API field API.TOKEN contain the thread token value? 

The OPS/MVS API field API.TOKEN does not contain the value from the THREAD-TOKEN field that is part of the THREAD-STATS record, Ifcid 148.

As described in the product documentation, section "Exception Action to Notify CA OPS/MVS", this field "Specifies a unique value for the instance of an exception for a data collector".  It is a way of uniquely identifying the instance of the exception to the OPS/MVS environment.

If you wish to cancel the thread, it is recommended you use the option on the Exception Actions Part 2 screen to issue the PTT command to Cancel a thread. You can include the &ACEXXXX exception variable field in the PTT command text to ensure a specific thread is cancelled.
