Connection pooling is turned on by default as specified in the official ODP.NET documentation on Connection String Attributes (default: Pooling = true).

So, if your connection string omits any kind of connection pool setting, you will get a connection pool with the following basic default settings, again based on that same official ODP.NET documentation page on Connection String Attributes:

• Connection Timeout = 15: Maximum time (in seconds) to wait for a free connection from the pool.
• Decr Pool Size = 1: Number of connections that are closed when an excessive amount of established connections are unused.
• Incr Pool Size = 5: Number of new connections to be created when all connections in the pool are in use.
• Max Pool Size = 100: Maximum number of connections in a pool.
• Min Pool Size = 1: Minimum number of connections in a pool.

The documentation mentions other interesting default pool values as well that you may want to read about as well.
