Session failure component data flows

This chapter contains information on the procedure IBM Z Performance and Capacity Analytics uses to process session failure data from the NetView session monitor.

Session failures

Session failure can occur when a session starts or ends. These types of problems can cause session failures:

  • The terminal and the application cannot agree on the terms for the communication (a bind failure).
  • The network does not have any available route or resource to establish the communication.
  • An explicit route is deactivated.

Session awareness data is reported by VTAM, processed by the NetView session monitor, written to SMF, and collected by IBM Z Performance and Capacity Analytics.

Note: Session awareness data can be filtered by VTAM; IBM Z Performance and Capacity Analytics does not collect the filtered data.
