Enabling zERT aggregation

You turn the zERT aggregation function on in the TCP/IP stack by specifying the GLOBALCONFIG ZERT AGGREGATION parameter in the TCP/IP profile data set. Enabling zERT aggregation causes the TCP/IP stack to collect cryptographic protection summary information for security sessions involving TCP and Enterprise Extender connections that terminate at the stack.

Guideline: Because zERT aggregation summarizes information collected by zERT discovery processing, zERT discovery must be enabled for zERT aggregation to operate; however, you do not have to enable SMF recording of zERT connection detail records for zERT aggregation to function correctly.

Results: If you dynamically enable zERT aggregation using VARY OBEYFILE, zERT does not collect summary information about TCP and Enterprise Extender connections that were established before enabling zERT aggregation.

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