Recently I have been doing the setup of Oracle Middleware products where I came across two type of data sources that are recommended for RAC database connectivity. They are- Active Grid Link/Grid Link Multi Data Source The question arises which one should I use and why? And, the answer is - Active Grid Link (AGL) Below are some facts provided by Oracle- AGL is a superior implementation to Multi Data Source (MDS) for supporting RAC clusters. The following section provides additional information on the benefits of AGL data sources. AGL: Requires one data source with a single URL. Multi data sources require a configuration with n generic data sources and a multi data source. Eliminates a polling mechanism that can fail if one of the generic data sources is performing slowly. Eliminates the need to manually add or delete a node to/from the cluster. Provides a fast internal notification (out-of-band) when nodes are available so that connections are load-balanced to
