Hi All,
I want to load Cache cache for every 60 min, For that At first I want to maintain Cache Load time (Time Stamp),Here I maintain Cache Load time in Shared Variable. For every message , I want to check elapsed time , difference between current time stamp , Cache Load time.
I need to maintain Cache Load Time in Variable for every 60 min , It should be there for every message.For first time Shared Variable Used successfully , but after 60 min ,We cannot reassign Time Stamp of after Cache Reload in Shared Variable.
How to resolve this Issue ?

Can you please explain why you made this statement

Are you getting an error?
How are you synchronising access to the shared variable?
Are you using more than one instance of the flow?
a little (or maybe a lot) more detail about the exact problem you are encountering would help a lot.

Hi
I did not get any error, but I did not get other than first time we can assign value to the shared variable , it would not take , It did not throw an Exception , But modified value not not assigned to shared variables.
So We cannot get modified Cache Load Time in the Shared variable ,So I got wrong result.
If broker will restart , it will take first time correctly.

There's a problem with your code. There's no reason why if you assign a value to a shared variable it will not "take" (to use your rather non-technical term) any more than if you assign a value to a local variable it doesn't change.
As my worthy associate points out, where there is a difference is why access is synchronized across different flows and you need to consider that.
