= Configuring JDBC string-based cache stores

Configure {brandname} caches with JDBC string-based cache stores that can connect to databases.

.Prerequisites

* Remote caches: Copy database drivers to the `server/lib` directory in your {brandname} Server installation.
* Embedded caches: Add the `infinispan-cachestore-jdbc` dependency to your `pom` file.

.Procedure

. Create a JDBC string-based cache store configuration in one of the following ways:
+
* Declaratively, add the `persistence` element or field then add `string-keyed-jdbc-store` with the following schema namespace:
+
[source,xml,options="nowrap",subs=attributes+]
----
xmlns="urn:infinispan:config:store:jdbc:{schemaversion}"
----
+
* Programmatically, add the following methods to your `ConfigurationBuilder`:
+
[source,xml,options="nowrap",subs=attributes+]
----
persistence().addStore(JdbcStringBasedStoreConfigurationBuilder.class)
----

. Specify the dialect of the database with either the `dialect` attribute or the `dialect()` method.
. Configure any properties for the JDBC string-based cache store as appropriate.
+
For example, specify if the cache store is shared with multiple cache instances with either the `shared` attribute or the `shared()` method.
+
. Add a JDBC connection factory so that {brandname} can connect to the database.
. Add a database table that stores cache entries.
