JDBC Driver Implementation and Configuration › DataSource Connection Parameters › DatacomConnectionPoolDataSource

DatacomConnectionPoolDataSource

The DatacomConnectionPoolDataSource class implements the JDBC ConnectionPoolDataSource interface, and is used with an application server that provides container managed connection pooling to establish a pooled connection to a CA Datacom database.

An application server typically provides visible DataSource implementation that references a ConnectionPoolDataSource and is exposed to the application as a standard DataSource. Connection pooling is transparent to the application.

The DatacomConnectionPoolDataSource is used by the application server connection pool manager to administer the pool of connections for a particular data source.

initialPoolSize

Specifies the number of connections that the pool manager should initially allocate.

maxIdleTime

Specifies the interval in seconds that a pooled connection can be idle before it is closed.

maxPoolSize

Specifies the maximum number of connections that the pool manager should allocate.

MaxStatements

Specifies the maximum statement pool size not used.

minPoolSize

Specifies the minimum number of available connections that the pool manager should maintain.

propertyCycle

Specifies the interval in seconds that the pool manager should wait before enforcing these policies.

Note: For more information about deploying and using DataSource and ConnectionPoolDataSource objects to connect to a database, see JDBC 4.0 Specification, available at www.java.sun.com. Detailed information for these interfaces is also included in the JSDK javadoc.

Detailed information about the CA Datacom Server implementation methods is included in the installed javadoc that can be optionally selected when custom installation is chosen (CA Datacom Server 11.exe).
