Non-inactivation events

For the events described in this section, the performance monitor can enable automatic data delivery on byte 5, bit 6 of the Start Performance Data Collection CNM RU for the event.

Virtual route blockages
Basic route data is reported for an individual virtual route when it becomes blocked and again when it is subsequently unblocked. The flow control state passed within the basic route data distinguishes the two cases.
HPR path switch
RTP connection data is reported when an HPR path switch occurs. To distinguish this record, byte 8 of the RTP data vector is set to B'1000 0000' or B'0010 0000'. For more information, refer to z/OS Communications Server: SNA Customization.

When an HPR path switch occurs with a CP name change, a ‘resource inactivation’ is delivered if the old CP name is being monitored. Collection occurs for the new CP name only if a ‘start collection’ has been issued for the endpoint.
Application recovery data is reported when an application recovers on a VTAM® in a sysplex that supports multinode persistent sessions.
