Class RedshiftConnectionPoolDataSource

java.lang.Object

com.amazon.redshift.ds.common.BaseDataSource

com.amazon.redshift.ds.RedshiftConnectionPoolDataSource

All Implemented Interfaces:

Serializable, Wrapper, Referenceable, CommonDataSource, ConnectionPoolDataSource, DataSource

Direct Known Subclasses:

ConnectionPool, DataSource, Jdbc3ConnectionPool

public class RedshiftConnectionPoolDataSource
extends BaseDataSource
implements DataSource, ConnectionPoolDataSource, Serializable

Redshift implementation of ConnectionPoolDataSource. The app server or middleware vendor should provide a DataSource implementation that takes advantage of this ConnectionPoolDataSource. If not, you can use the Redshift implementation known as PoolingDataSource, but that should only be used if your server or middleware vendor does not provide their own. Why? The server may want to reuse the same Connection across all EJBs requesting a Connection within the same Transaction, or provide other similar advanced features.

In any case, in order to use this ConnectionPoolDataSource, you must set the property databaseName. The settings for serverName, portNumber, user, and password are optional. Note: these properties are declared in the superclass.

This implementation supports JDK 1.3 and higher.

Method Detail

getDescription

public String getDescription()

Gets a description of this DataSource.

Specified by:

getDescription in class BaseDataSource

Returns:

description of this DataSource-ish thing

getPooledConnection

public PooledConnection getPooledConnection()
                                     throws SQLException

Gets a connection which may be pooled by the app server or middleware implementation of DataSource.

Specified by:

getPooledConnection in interface ConnectionPoolDataSource

Throws:

SQLException - Occurs when the physical database connection cannot be established.

getPooledConnection

public PooledConnection getPooledConnection(String user,
                                            String password)
                                     throws SQLException

Gets a connection which may be pooled by the app server or middleware implementation of DataSource.

Specified by:

getPooledConnection in interface ConnectionPoolDataSource

Throws:

SQLException - Occurs when the physical database connection cannot be established.

isDefaultAutoCommit

public boolean isDefaultAutoCommit()

Gets whether connections supplied by this pool will have autoCommit turned on by default. The default value is true, so that autoCommit will be turned on by default.

Returns:

true if connections supplied by this pool will have autoCommit

setDefaultAutoCommit

public void setDefaultAutoCommit(boolean defaultAutoCommit)

Sets whether connections supplied by this pool will have autoCommit turned on by default. The default value is true, so that autoCommit will be turned on by default.

Parameters:

defaultAutoCommit - whether connections supplied by this pool will have autoCommit
