5.	set mode/unsupp	Sets mode to unsupported.
6.	set trace	Stops the trace.
7.	set mode/nounsupp	Sets mode back to supported.

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.

8.6Contents 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.
