Can multiple Oracle9i Application Server or mid-tier instances, share the same Infrastructure?
It is possible to share the same Infrastructure with multiple Oracle9i Application Server instances. Oracle strongly recommends using this topology, and encourages the deployment of Oracle9iAS instances on systems apart from the host which has Oracle9iAS Infrastructure configured. If there is a requirement to have multiple Oracle9iAS Infrastructures shared by different set of Oracle9iAS instances, that topology is also supported. These set of Oracle9iAS instances must exist on different Hosts. Please refer to Oracle9iAS Release 2 (9.0.2) Installation Guide and Oracle9i Application Server Administrator’s Guide for more information.
