How to clear cache for a specific component in R12

As we all know the normal tendency for clearing cache in Oracle Apps is to delete the $COMMON_TOP/_pages directory.In 11i, after deleting we dont have to recompile the jsps but in R12 we have to recompile the pages since s_jsp_main_mode is set to justrun by default which is in turn updated in orion-web.xml

How can i clear cache for a specific component of Oracle Apps R12 viz., iprocurement, istore etc.,
Is this even possible ? Yes it is and this option comes handy when somebody modifies a jsp page which is part of say istore,then it makes sense to clear cache for istore and not for the whole server.

Clearing cache for specific Component/Application in R12

Login as sysadmin
Select Functional Administrator responsibility
Go to Core Services ==> Caching Framework ==> Tuning
Query the application (for example iStore) or by Name or code.
Select the component and clear the cache.

Note: For some specific configuration changes, we need to bounce Apache also.

Clearing Global Cache in R12

a) Go to Functional Administrator Responsibility
b) Go to Core Services ==> Caching Framework
c) Go to Global configuration and clear all the cache from there.(Only If you want to clear all the  cache)
