Hmm, so a schedule is returned by scheduleResourceOperation, which suggests that the operation was scheduled, but no operation history ever gets created... Did you check the Server log for errors? Can you tell if the operation is getting executed in the corresponding Agent?

Ian,

Thanks for the suggestion.  I tried removing the criteria (there is really only resource id and job id) but neither worked.  I went ahead and commented out my waitForOpertion() call and proceeded to wait and then try the getSnapshotReport() call and started having a problem, which surprised me because that code was working before.  I am now wondering if that error might shed some light on why the waitForOperation() call is failing.

The new failure is:

2011-08-16 15:53:41,508 INFO  [com.ocsystems.rtiplugin.RtiAlertSender] RTI Alert: get snapshot 2011-08-16T20:51:41..2011-08-16T20:53:41 in 12702

{snip]

Again, the sequence of events is:

- invoke operation to turn on diagnostics
- wait for operation to complete (commented out now)
- delay for 2 minutes
- invoke getSnapshotReport()

The first invoke and the wait seem to complete normally (I see the operation being performed by the agent) then the traceback starts at the getSnapshotReport() call.

I have attached the full traceback if it's useful.

Any ideas?

Steve

This is just a guess but perhaps jobId or one of the other history
criteria filters is excluding the history you're trying to lookup for
some reason. I'd try commenting out some of the filters one by one and
see if the query returns any histories. This will allow you to determine
if any history at all is getting created for the schedule request. If
one is, then you can try to figure out why your criteria is not matching it.

Heiko,

Here is the relevant code to schedule the operation:

               private static final int DEFAULT_OPERATION_TIMEOUT = 240;

               ResourceOperationSchedule schedule =
                  operationManager.scheduleResourceOperation(
                        overlord,
                        collectorId,
                        "setBtmOption",
                        0,
                        0,
                        0,
                        DEFAULT_OPERATION_TIMEOUT,
                        cfg,
                        "RTI Alert trace until " + interval);

               //TODO fix this....
               ResourceOperationHistory hist = waitForOperation(schedule);

and to wait for completion:

      private ResourceOperationHistory
waitForOperation(ResourceOperationSchedule schedule) throws Exception
      {
         final int NUM_INTERVALS = 240;
         final int INTERVAL_DURATION = 1000;

         OperationManagerLocal operationManager =
LookupUtil.getOperationManager();
         SubjectManagerLocal subjectManager = LookupUtil.getSubjectManager();

         ResourceOperationHistoryCriteria criteria = new
ResourceOperationHistoryCriteria();
         criteria.addFilterJobId(schedule.getJobId());
         criteria.addFilterResourceIds(schedule.getResource().getId());
         criteria.addSortStartTime(PageOrdering.DESC);
         criteria.setPaging(0, 1);
         criteria.fetchOperationDefinition(true);
         criteria.fetchParameters(true);
         criteria.fetchResults(true);

         ResourceOperationHistory history = null;

         int i = 0;

         while (history == null&&   i<   NUM_INTERVALS)
         {
            try
            {
               Thread.sleep(INTERVAL_DURATION);

               List<ResourceOperationHistory>   histories =

operationManager.findResourceOperationHistoriesByCriteria(subjectManager.getOverlord(),
criteria);

               if (histories != null&&   histories.size()>   0)
               {
                  log.info("RTI Alert:  hist = " +
histories.get(0).toString());
               }

               if (histories != null&&
                     histories.size()>   0&&
                     histories.get(0).getStatus() !=
OperationRequestStatus.INPROGRESS)
               {
                  history = histories.get(0);
               }
            }
            catch (InterruptedException ie)
            {
               log.info("RTI Alert: operation interrupted...");
               break;
            }
            ++i;
         }

         if (history == null)
         {
            log.info("RTI Alert: operation timed out...");
            throw new Exception("Operation timed out.");
         }
         else if (history.getStatus() != OperationRequestStatus.SUCCESS)
         {
            log.info("RTI Alert: error..." + history.getErrorMessage());
            throw new Exception("JON Server error: " +
history.getErrorMessage());
         }

         return history;
      }

Last night I tried just ignoring the waitForOperation() call since my
logic waits for a set period afterwards, and things seemed to work, but
this is not ideal since I won't know about any errors performing the
first operation.
Is
Thanks.

I was looking through the RHQ code and I found the OperationSender
alert.  It looks like this example did exactly what I was trying to do,
but apparently the wait code was commented out for some unspecified
reason.  This doesn't seem too promising...
Can't tell at the moment.
When setting up an operation in general, we can supply a timeout
in seconds/minutes etc that we wait for before we consider the
operation as timed out. This is set to 0 in the OperationsSender,
which means "no timeout".

Could you post a code-snippet, so that we may get a better idea
of what you are doing and what may go wrong?
