Can i schedule activities in WF, for example can i set a schedule so that a particular activity has to start at a particular time, is schedulig server helpful for this purpose, from what i read in the architecture doc it says it is for notifications only.

In that case how can i schedule activities in timely manner?

What kind of activity are you talking about?

You could set up a NOOP activity with an expiration time before the activity that you want scheduled. The instance will wait in your NOOP for a set period of time (minutes, hours, days, weeks, months, years) before expiring and going into your scheduled activity. Yes, the scheduling server handles activity expirations as well as notifications.

You may also be able to do something with suspending the instance for a set period of time (the scheduling server handles this as well), but this may get a bit tricky.

Just an FYI on the scheduling server and expiration times.... just because you set an activity to expire after 5 minutes, it does not mean that the instance will get kicked out exactly 5 minutes after it entered. The items won't expire until the scheduling server runs, and that is set by a time intervol in BT. If your scheduling server only runs once a day, for example, your instances will only expire once a day, no matter what your expiration time is set to.

I believe that Josh has already given you the answer to this.

You have an activity prior to the activity you want to start that expires at approx 5:30, once that activity expires your activity runs.

If you want this to happen at EXACTLY 05:30:00.000000 I think you are out of luck, you can get close, to it but it will always be +/- the value you have specified for your notification interval on the Scheduling serverfmczchk -c inst:m,RTAuthenticationExitTypeServer,JAVA -y FMC
