| Keep your distributed cache in sync with an outside data source by programming and installing application plug-ins for your region. |
| |
| - **[Overview of Outside Data Sources](chapter_overview.html)** |
| |
| <%=vars.product_name_long%> has application plug-ins to read data into the cache and write it out. |
| |
| - **[Configuring Database Connections Using JNDI](configuring_db_connections_using_JNDI.html)**. |
| |
| Use JNDI to maintain a connection pool that includes outside data sources. |
| |
| - **[How Data Loaders Work](how_data_loaders_work.html)** |
| |
| By default, a region has no data loader defined. Plug an application-defined loader into any region by setting the region attribute cache-loader on the members that host data for the region. |
| |
| - **[Implement a Data Loader](implementing_data_loaders.html)** |
| |
| Program a data loader and configure your region to use it. |
