concurrent_act_top - Concurrent activity top monitor element

The high watermark for the concurrent activities (at any nesting level) in a service subclass since the last reset.

Note: This element monitors the highest concurrent execution of all activities, including those activities that do not participate in the CONCURRENTDBCOORDACTIVITIES threshold. For example, although CALL statements do not count towards the concurrency that is enforced by the CONCURRENTDBCOORDACTIVITIES threshold, they are included in the concurrent activity high watermark measurement.
