Does Oracle Clusterware support application vips?
Yes, with Oracle Database 10g Release 2, Oracle Clusterware now supports an “application” vip. This is to support putting applications under the control of Oracle Clusterware using the new high availability API and allow the user to use the same URL or connection string regardless of which node in the cluster the application is running on. The application vip is a new resource defined to Oracle Clusterware and is a functional vip. It is defined as a dependent resource to the application. There can be many vips defined, typically one per user application under the control of Oracle Clusterware. You must first create a profile (crs_profile), then register it Clusterware (crs_register). The usrvip script must run as root.
