OCA and NonStop Debugging Tools
You can also run Accelerator on a TNS object file that has been previously accelerated 
for the TNS/E environment by OCA:
See the H-Series Application Migration Guide for further information about using OCA 
and the Accelerator.
OCA and NonStop Debugging Tools
You can use either Visual Inspect or Native Inspect to debug programs accelerated by 
OCA. Source-level (symbolic) debugging of accelerated programs is very similar to 
TNS programs. However, machine-level debugging of accelerated programs is limited, 
and rarely necessary. See Section 7, Debugging OCA Programs for further information 
about using OCA with Visual Inspect and Native Inspect.
OCA and EPTRACE
EPTRACE is a performance investigation tool designed for the Guardian environment. 
It reports detailed counts of trap events and provides a complete trace log of these 
events so you can locate, diagnose, and resolve all trap-causing locations in a 
program.
EPTRACE reports two types of information in the trace log:
•
Counters
Reports individual counters for each process, including interrupt processes. 
The per-CPU totals equal the sum of all process counters.
•
Traces
