PoolingDataSource

public PoolingDataSource()

Method Detail

init

public void init()

Initializes the pool by creating the initial amount of connections.

Specified by:

init in interface XAResourceProducer

getTestQuery

public java.lang.String getTestQuery()

Returns:

the query that will be used to test connections.

setTestQuery

public void setTestQuery(java.lang.String testQuery)

When set, the specified query will be executed on the connection acquired from the pool before being handed to the caller. The connections won't be tested when not set. Default value is null.

Parameters:

testQuery - the query that will be used to test connections.

getPreparedStatementCacheSize

public int getPreparedStatementCacheSize()

setPreparedStatementCacheSize

public void setPreparedStatementCacheSize(int preparedStatementCacheSize)

getIsolationLevel

public java.lang.String getIsolationLevel()

setIsolationLevel

public void setIsolationLevel(java.lang.String isolationLevel)

getConnection

public java.sql.Connection getConnection()
                                  throws java.sql.SQLException

Specified by:

getConnection in interface javax.sql.DataSource

Throws:

                                    throws RecoveryException

Description copied from interface: XAResourceProducer

Prepare the recoverable XAResource producer for recovery.

Specified by:

startRecovery in interface XAResourceProducer

Returns:

a XAResourceHolderState object that can be used to call recover().

Throws:

Throws:

RecoveryException - thrown when an error occured while releasing reserved resources.

setFailed

public void setFailed(boolean failed)

Description copied from interface: XAResourceProducer

Parameters:

failed - true is the resource must be considered failed, false it it must be considered sane.

close

public void close()

Description copied from interface: XAResourceProducer

Release this XAResourceProducer's internal resources.

Specified by:
