The multi-pools are used to store the connection in 2 levels inside the pool and configure it accordingly. There are two ways in which the Multi-pools can be set up:

1. The multi-pool can be made as a backup if the connection to the database event fails.

2. The multi-pool can be setup as a load balancing server that will allow the server to give away some load to alternative server to balance the work and give higher performance. The multi-pools are used in the configuration of Web logic JDBC features and allow it to be chosen according to the requirements of the server from time to time.
