Adding EXT_MON in the RESOURCES Section

1.3.2.2 Adding EXT_MON in the RESOURCES Section

Collection and calculation of certain metrics (such as Service Metrics and IPC Queue Metrics in MIB), consumes CPU time and potentially impacts Oracle Tuxedo performance. Oracle Tuxedo uses the EXT_MON OPTIONS parameter in the UBBCONFIG file *RESOURCES section to allow MIB performance sensitive metrics collection.

If the indicator is specified, all metrics listed in the Tuxedo Targets section are collected in MIB; otherwise, if the indicator is not specified, the following metrics are not collected by Oracle Tuxedo:

Tuxedo Server Service metrics
Tuxedo Server IPC Queue metrics
Tuxedo Bridge IPC Queue metrics

The metrics collection policy changes immediately once you modify this parameter setting.
