Managing Node Agents on a NonStop Operating System

Profiling Applications
Collecting Profile Data
Profiling with -Xeprof
Table 5-1 Supported –Xeprof options
time_on
time_slice
On NonStop operating systems, the time
interval between the start and stop signals
must be more than five minutes. This is
because the Java thread switching process
is slow due to the non-preemptive nature
of the NonStop operating system. As a
result, the asynchronous signals might be
lost if they are posted to the NonStop OS
Java process at very short intervals.
times=quick|thorough
This option is not supported on NonStop
operating systems.
Profiling with Zero Preparation
This feature is supported on NSJ 5.1, NSJ 6.0, and later versions only.
Profiling with –agentlib:hprof
Table 5-2 Supported -agentlib:hprof options
cpu=samples|times|old cpu=samples is not supported on
NonStop operating systems.
