## Clearing Cache

OIPA uses coherence to cache the information such as, screen rules, business rules, transactions, authorization, user session etc. This web service can be used to clear the following three cache(s) regions maintained by OIPA:

- WEB
- CORE
- PAS

Whenever there is any change in business configuration like business rules, transactions, authorization, etc. in the rules palette, you can call this web service to clear the cache after any update in OIRP. This action logs out all the logged in users. When OIPA users re-login, the cache is refreshed with the latest data and the changes are reflected in the application.

This service eliminates the need to re-start the server to get the latest data. When a user sends a Cache request, the system clears the old data from the cache and loads the latest data to use. These caches will maintain the old data until the clear cache service is called.

Authorization to the Clearing Cache service is controlled from the Rules palette. After giving authorization to a security group, a user belonging to that security group can access the service.
