Method Detail

initialise

public String initialise(String dbName)

Description copied from interface: ConnectionModifier

Initialise the modifier.

Specified by:

initialise in interface ConnectionModifier

Returns:

the database name to use.

createXid

public Xid createXid(Xid xid)
              throws SQLException,
                     NotImplementedException

Description copied from interface: XAModifier

Given an Arjuna xid, create a local driver representation. Some drivers expect their own implementations to be used, despite the fact that the JTA does not mention this!

Specified by:

createXid in interface XAModifier

Throws:

SQLException

NotImplementedException

getConnection

public XAConnection getConnection(XAConnection conn)
                           throws SQLException,
                                  NotImplementedException

Description copied from interface: ConnectionModifier

Return a new connection.

Specified by:

getConnection in interface ConnectionModifier

Throws:

SQLException

NotImplementedException

supportsMultipleConnections

public boolean supportsMultipleConnections()
                                    throws SQLException,
                                           NotImplementedException

Description copied from interface: ConnectionModifier

Does their JDBC driver support multiple connections in a single transaction?

Specified by:

supportsMultipleConnections in interface ConnectionModifier

Throws:

SQLException

NotImplementedException

setIsolationLevel

public void setIsolationLevel(Connection conn,
                              int level)
                       throws SQLException,
                              NotImplementedException

Specified by:

setIsolationLevel in interface ConnectionModifier

Throws:

SQLException

NotImplementedException

xaStartParameters

public int xaStartParameters(int level)
                      throws SQLException,
                             NotImplementedException

Description copied from interface: XAModifier

Return the xa_start parameters for this level.

Specified by:

xaStartParameters in interface XAModifier

Throws:

SQLException

NotImplementedException

requiresSameRMOverride

public boolean requiresSameRMOverride()

Description copied from interface: ConnectionModifier

This method indicates whether the driver supports TMJOIN reliably. If isSameRM returns true but does not support xares1.start(xid1,TMNOFLAGS); xares2.start(xid2, TMJOIN) then you need to make sure you set this to true to use a wrapped XAR that returns false for the driver. See JBTM-2264 for more details.

Specified by:

requiresSameRMOverride in interface ConnectionModifier
