How to handle connection pooling in oracle?

1. Use Oracle Connection Pooling: Oracle database provides built-in connection pooling functionality through the Universal Connection Pool (UCP). UCP can be configured to manage a pool of database connections and handle connection requests efficiently.
2. Configure Connection Pool Settings: When setting up connection pooling in Oracle, configure the connection pool settings such as maximum and minimum connections, timeout settings, and other parameters according to the requirements of your application.
3. Use Connection Pooling in Application Code: Modify your application code to use the connection pool instead of creating a new connection for each database request. Use the UCP API to get connections from the pool and return them back when done.
4. Implement Proper Exception Handling: Make sure to implement proper exception handling in your application code to handle connection errors and failures gracefully. This will ensure that the connection pool remains stable and connections are properly managed.
5. Monitor and Tune Connection Pool: Regularly monitor the performance of the connection pool and tune its configuration settings as needed. Keep an eye on connection usage, pool size, and other metrics to optimize the performance of the connection pool.
6. Consider Using Connection Pooling Libraries: If you prefer not to use the built-in Oracle connection pooling mechanism, you can also consider using third-party connection pooling libraries such as Apache DBCP or C3P0. These libraries provide similar connection pooling functionality and can be easily integrated into your application.

By following these best practices, you can effectively handle connection pooling in Oracle and ensure optimal performance and scalability for your database applications.
