Do all Oracle9iAS Instances on the host have to share the same Oracle9iAS Infrastructure?
Yes, all Oracle9iAS Instances such as J2EE and Web Cache (only if clustering or single sign on features are used), Portal and Wireless, Business Intelligence and Forms, as well as Unified Messaging on the same host have to share the same Oracle9iAS Infrastructure. The Infrastructure instance can either be on the same host or on a separate host. When the instances share the same Oracle9iAS Infrastructure, they all join the same “Farm”.
