ESS (Enterprise Scheduler Service) for Inbound JCA Adapters in SOA 12C

Enterprise Scheduler Service (ESS) is a scheduler that is part of SOA Suite 12c. ESS supports a number of scheduling activities around the SOA Suite.
With the help of em console, we can manage job requests, define metadata and schedule jobs, and APIs to define metadata and create schedules in ESS.
In this section, we are going to create a schedule and assign it to a Inbound JCA (jms,file,db polling,etc..) adapter.

Scenario: Deactivate the DB adapter at 10 PM everyday and activate it back at 8 AM next morning. In this case, records created  by system between 10 PM to 8 AM will not be processed immediately.

Expand Scheduling Services, Right click on ESSAPP. Job Requests-> Define Schedules.

Click on Create to create a new schedule.

Now we have to create 2 Schedules, One for activation and other for Deactivation. (Sequence doesn't matter)
Please note that package have to be mentioned as "soa".
First Deactivation,

 Now Activation,

If you want to look at the schedules, you can just click on name of one the schedules.

Now you can go to your composite, And click on adapter.

 Click on calendar icon on the right corner.

Select the schedules created in above steps and click on Apply Schedules.

And you are done!!!!

Note: I have experienced a issue with clustered ESS servers, the schedules created were not displaying in the adapter. So i brought down one of the ESS server and tried the same and it worked. Not sure whether its product bug, so keep this as a workaround if adapters are not showing the schedules created.
