Running a trace can affect performance, so be sure to turn it off again when done
(see step 6).

8.5 Dealing with a Looping Process

If your system appears to be hung, this may be caused by an RTR process looping.
To analyze the problem, do the following:

1.

Enter the

SHOW PROCESS RTRACP/CONTINUOUS

OpenVMS command.

2.

Examine the running process, which will be in computable mode. PC samples
typically assume values with a narrow range, or recur frequently.

3.

Lower the priority of the ACP process.

4.

Enter the OpenVMS

ANALYZE/SYSTEM SET PROCESS RTRACP

command.

5.

Enter the

SHOW CALL/NEXT

command until you see PC values corresponding to

RTR software.

6.

If you cannot resolve the performance issues yourself, send the logs and your
process output to DIGITAL Multivendor Customer Services using normal
problem reporting channels.

8.6 Contents of the RTR Journal File

With RTR Version 2, the only way to examine the content of journal files was to
stop the ACP. With RTR Version 3, you can do this without stopping RTR using
the

DUMP JOURNAL

command.
