Should I use WebLogic Server MultiPools or Oracle RAC/TAF?
MultiPools and Oracle RAC/TAF provide different levels of failover capabilities. Depending on the Oracle RAC/TAF configuration, it can fail over some of the objects used in one database to the failover node. Please check the related documentation about RAC / TAF on Oracle’s site and also our Oracle RAC (Real Application Clusters) Configuration and Testing Pattern for details. RAC/TAF is an additional feature from Oracle with additional charge. BEA’s MultiPool (configured for high availability) is part of the WebLogic Server distribution and included in the charge. It provides the ability to have a list of JDBC connection pools, for which the MultiPool will try to provide a connection. If one database is down, it will try the next pool in the list. It cannot fail over any objects from the failed database to the failover instance. The decision to use one over the other depends on the level of failover transparency you need and the amount of money that can be spent. MultiPool functionalit
