add your server details like mentioned below and open in broswer, it completes cache refresh

http ://<server>:<port>/CPACache/refresh?mode=full

Provide your PI credetials , full cache refresh perfroms completes refresh of System cache.

Thanks for the help sekhar, i got one more small doubt, i think we can do that manually by going into administration aswell right?

when i have given my PI credentials its throwing error that i am not authorized, do i have to consult basis people to get authorization

yeah.may be your user did not have sufficent roles to perform the same, check with basis and ask them to provide the roles to your user id.

Hello,

Check the SAP note #1600539 PI AF: Manual Execution of a CPA Cache Refresh.

"To be able to call this URL, Group or Role SAP_XI_ADMINISTRATOR_J2EE
must have been assigned to your dialog user. You can for example use the
PISUPER user.

Note: It is no longer possible to call this page with a service user
(for example PIDIRUSER)."

"Note: A full CPA Cache refresh has immediate impact on the message
processing. On large systems a full CPA cache refresh can take up to an
hour. During this time only restricted message flow is possible."

So, you need to be careful when doing a full CPA cache refresh (especially in a PRD environment).
