UCP JDBC connection pools are configured using connection pool properties. The properties have
set methods that are available through a pool-enabled data source instance. The methods are a convenient way to programmatically configure a pool. If no pool properties are set, then a connection pool uses default property values.
The following example demonstrates configuring connection pool properties. The example sets the connection pool name and the maximum/minimum number of connections allowed in the pool.
PoolDataSource pds = PoolDataSourceFactory.getPoolDataSource(); pds.setConnectionPoolName("JDBC_UCP"); pds.setMinPoolSize(4);pds.setMaxPoolSize(20);
UCP JDBC connection pool properties may be set in any order and can be dynamically changed at run time. For example,
setMaxPoolSize could be changed at any time and the pool recognizes the new value and adapts accordingly.
