This means that you need to use this virtual IP and not hostname:
- in listener.ora - in tnsnames.ora on the database server - in tnsnames.ora on the application server - in configuration files used by thin JDBC driver if your applicationis java-based
- when configuring backup (Legato Networker/Veritas Netbackup) and monitoring (Open View, etc)
If your application is ruconnects to the database using JDBC connection pool (or .Net connection pool) then it should re-connect automatically.
You also need to minimize time it takes to bring the database up on the failover node (parameter fast_start_mttr_target). Received on Sat Nov 14 2009 - 17:25:24 CST
