Hi all,

I am having a simple scenario where I am using an activity to notify process administrator for the delay in work item. Say, after 30 sec of delay, admin is supposed to get the notification. When deployed, I don't see any work item in the notification worklist after 30 secs delay. But the History tab shows that the first notification is sent after 30 secs.
Does anyone know how do I check the notified work item?

Thanks in advance

Is your Scheduling Server running? If it is a development/test environment, try to restart it and see.

A 30 second notification is a pretty short interval.... In addition to the scheduling server running, you are going to have to change the Notification Check Interval which defaults to 1 hour. To guarantee 30 seconds you are going to need a Check Interval of less than 15 seconds.... Which is Extremely short

Thanks for the reply.

I started the scheduling server and now it is in active mode. But can you please tell me how do I change the check interval or notification check interval. I just had 30 seconds for testing. In real world it is going to be 24, 48 and 72 hours. And which is related to change in the priority too. I don't know if this is feasible or not, correct me if I am wrong. The person who will be notified for the work item delay should able to see the work item by the high priority.

Thanks again

You can change the check interval in Buildtime.
I donno if you can do it anywhere else too.

Go to network tab, then domain properties, Server tab ,
click on the complete scheduling server settings and you can specify the check interval there.

hi mm
You have to restart your server if you make changes in the network tab , for changes to take effect.(may be you already know this)

Just out of curiosity, what is the impact if I have notification set to be 5 minutes after a particular work item is ready, and in contrast having the following scheduling server options:

I know that the check interval set to 5 minutes means that the admin server will essentially perform a ping operation on the rest of the server, and if any are down, it brings them up. I also realize that the notification check interval being set to 10 minutes means that every 10 minutes the scheduling server will check to see if there are any activities out there that are overdue.

SERVER
TYPE SCHEDULING_SERVER
START_MODE IMMEDIATE
CHECK_INTERVAL 5 MINUTES
CREATE_NOTIFICATION_ITEMS_THRESHOLD 10
DELETE_NOTIFICATION_ITEMS_THRESHOLD 100
NOTIFICATION_CHECK_INTERVAL 10 MINUTES

I am curious however and am wondering..., does this mean that the Notification time has to be less then that of the NOTIFICATION_CHECK_INTERVAL and/or the CHECK_INTERVAL

Praveen:

This is how the Intervals work according to my understanding:

1. Check Inteval is as you say a ping to the server by Admin server just to see if it is alive. This has no affect on Notifications/Expirations, unless of course your scheduling server has died.

2. Notification Check Interval is also as you say. The legnth of time between the Scheduling server checking for Expired/Notification activities. Each time the Scheduling server awakes, it checks to see if any new Expirations or Notifications need to be issued. When dealing with short intervals for Notify/Expire, say 10 minutes, you simply need to understand that if your Notification Check Interval is 5 minutes the Scheduling server will recognize that the interval has been reached sometime between 10 and 15 minutes of real elapsed time.

Hi guys,

I am back again with another question here. I have the admin notified couple of work items, my question is, can he just transfer the work item to someone else or check out the work item? I don't see the check out button next to work item when the admin got notified. If "No", when admin transfers the work item to someone else say X, can X check out the item? I don't see the check out button on the X's work list either. Or am I missing something here?

Thanks in advance.

What I think you are doing is looking at the Notification Item... You can only checkout a workitem.... Of course Admin can do any transfers that need to be done
