custom message for dispatcher running but no server connected CE7.31

Hi All,

We are on CE7.31 server and have requirement to configure /show custom html page /message when portal is down .

Query: How to achieve same?

I have got this sap note reference 1718909

it says com.sap.portal.runtime.dispatcher.ear (part of EPBASIS.SCA) needs to be adjusted in order for custom error handling to be added for the portal

Need exact location to download same from server ?

Also any other way to achieve same like I modified http error page layout by creating a custom properties file.

Regards,

Madhvika
