[Building Sakai] Delayed Announcement Email Notification

[Chris Ribble]

I can see the init() and destroy() of the ScheduledInvocationManagerImpl 
in my logs, and they coincide with server startup and shutdown. The only 
other mention of that service in there is 
"NoisierDefaultListableBeanFactory - Destroying singletons in" and 
ScheduledInvocationManagerImpl is listed in that list of beans. 

Looks like I'm going to have to start debugging.

Thanks for the help Matthew!

Right, it looks like every startup, the init() method tries first 
unschedule the job, then reschedule it to run forever every 
"SCHEDULED_INVOCATION_RUNNER_DEFAULT_INTERVAL" (which is defined as 600 
seconds, so 10 minutes). On the systems I'm looking at it's setup 
correctly.

I'm not sure what cases could cause the try/catch to fail though and cause 
a SchedulerException.

After checking the logs and I only have one instance of that error and it 
was 3 days before I started trying to run the quartz job. That seems 
really odd. 

If I am reading your first sentence correctly, I shouldn't have to setup 
the Quartz job? ScheduledInvocationManager should run on its own?

It looks like that should schedule itself in the init method otherwise 
throw an error. All of the issues that you describe look to be fixed. Do 
you see this error "failed to schedule" in the logs? 

./scheduler-component-shared/src/java/org/sakaiproject/component/app/scheduler/ScheduledInvocationManagerImpl.java 

                 public void init() {
                                 LOG.info("init()");
                      try {
                          registerScheduledInvocationRunner();
                       } catch (SchedulerException e) {
                          LOG.error("failed to schedule 
ScheduledInvocationRunner job", e);
                       }
                    }

Hi everyone, 

In our 2.7.1 instance we have noticed that when setting an announcement to 
be hidden until a later date and selecting the email notification to go 
out, nothing is sent upon the un-hide of the announcement. I have searched 
for some documentation or a JIRA ticket about this issue and found some 
information but I can't quite get it to work. So far, I have figured out 
that I need to get the ScheduledInvocationRunner quartz job to run on a 
regular basis. I set that up by adding the job in the job scheduler tool 
on the admin workspace and then setting a Cron trigger for every 5 
minutes. I waited for a while and nothing ever happened. I ran the job and 
my email was sent but any subsequent emails were not mailed out. I 
"somehow" finally got the job to run on a regular basis and everything was 
working fine. I decided to restart the instance to see what would happen 
and when it came back up the ScheduledInvocationRunner was not running. I 
need it to auto start when the instance comes back online. 

Am I headed in the right direction with this? Is there anything special I 
need to do to get this working properly? 

Thanks 
Chris
