Disabling zERT aggregation

You turn off the zERT aggregation function in the TCP/IP stack by either specifying either the GLOBALCONFIG ZERT NOAGGREGATION parameter or the GLOBALCONFIG NOZERT parameter in the TCP/IP profile data set.

Guideline: This is the default behavior.

Results: Using GLOBALCONFIG ZERT NOAGGREGATION to disable zERT aggregation has no effect on zERT discovery processing.

Disabling zERT aggregation causes the TCP/IP stack to not maintain summary statistics of the cryptographic characteristics of TCP and Enterprise Extender security sessions that terminate at the stack. Before disabling the zERT aggregation function, a final set of SMF Type 119 subtype 12 records is generated, if recording of zERT summary records is active. The final set of records is written to the z/OS® System Management Facility (SMF), the real-time zERT Summary NMI service, or both, depending on your choice of destination at the time zERT aggregation is disabled.

Results: If you dynamically disable zERT aggregation or zERT discovery using VARY OBEYFILE, any previous information collected by zERT aggregation is discarded.

For more information on disabling zERT aggregation, see GLOBALCONFIG statement in z/OS Communications Server: IP Configuration Reference.
