We are planning to configure the HA for our application ADF using webloigc server with 2 manage sever and one admin sever on seprate machines, and for the reports we are planning to use the oracle reports 11g.
Can anybody guide us where we need to install the Oracle Fussion middleware for reports.
I would create a separate Managed Server for Reports. If you also want to use a Cluster for Reports you will have to install the software on both servers and create a second Managed Server on Server 2.
For a detailed description of how to install Forms/Reports see:
For rough overview of the Clustering see: Adding a new node to a cluster
Hope this helps?
