-=== Using Oracle Universal Connection Pool
-
-[IMPORTANT]
-====
-To use the Universal Connection Pool (aka UCP) integration, the application must include the `hibernate-ucp` module jar (as well as its dependencies) on the classpath.
-====
-
-Hibernate also provides support for applications to use https://docs.oracle.com/en/database/oracle/oracle-database/23/jjucp/intro.html[Oracle Universal Connection Pool].
-
-Set all of your UCP settings in Hibernate prefixed by `hibernate.oracleucp.` and this `ConnectionProvider` will pick them up and pass them along to UCP.
-Additionally, this `ConnectionProvider` will pick up the following Hibernate-specific properties and map them to the corresponding UCP ones (any `hibernate.oracleucp.` prefixed ones have precedence):
-
-`hibernate.connection.url`:: Mapped to UCP's `URL` setting
-`hibernate.connection.username`:: Mapped to UCP's `user` setting
-`hibernate.connection.password`:: Mapped to UCP's `password` setting
-`hibernate.connection.isolation`:: Used to initialize `Connection` retrieved from UCP. See <<ConnectionProvider support for transaction isolation setting>>.
-`hibernate.connection.autocommit`:: Used to initialize `Connection` retrieved from UCP.
-Any other settings prefixed with `hibernate.oracleucp.`:: Will have the `hibernate.oracleucp.` portion stripped and be passed to UCP.
-
-[IMPORTANT]
-====
-You can pass further settings to the `Connection` provided by UCP by using the `hibernate.oracleucp.connectionProperties` property in the following manner:
-
-`hibernate.oracleucp.connectionProperties=oracle.jdbc.thinForceDNSLoadBalancing=true,oracle.jdbc.fanEnabled=true,oracle.jdbc.defaultConnectionValidation=SOCKET,oracle.jdbc.implicitStatementCacheSize=50,oracle.jdbc.loginTimeout=5000`
-====
-
-The Hibernate property `hibernate.oracleucp.connectionFactoryClassName` can be used to choose between:
-
-. a standard connection pool: `oracle.jdbc.pool.OracleDataSource`
-. a _replay_ connection pool: `oracle.jdbc.replay.OracleDataSourceImpl` which allows using [Transparent] Application Continuity capabilities to mask planned and unplanned downtime
