OracleXAResource

public OracleXAResource(java.sql.Connection pm_conn)
                 throws oracle.jdbc.xa.XAException

Method Detail

start

public abstract void start(javax.transaction.xa.Xid xid,
                           int flag)
                    throws oracle.jdbc.xa.XAException

end

public abstract void end(javax.transaction.xa.Xid xid,
                         int flag)
                  throws oracle.jdbc.xa.XAException

commit

public abstract void commit(javax.transaction.xa.Xid xid,
                            boolean onePhase)
                     throws oracle.jdbc.xa.XAException

prepare

public abstract int prepare(javax.transaction.xa.Xid xid)
                     throws oracle.jdbc.xa.XAException

forget

public abstract void forget(javax.transaction.xa.Xid xid)
                     throws oracle.jdbc.xa.XAException

rollback

public abstract void rollback(javax.transaction.xa.Xid xid)
                       throws oracle.jdbc.xa.XAException

recover

public oracle.jdbc.xa.Xid[] recover(int flag)
                             throws oracle.jdbc.xa.XAException

Obtain a list of prepared transaction branches from a resource manager. The transaction manager calls this method during recovery to obtain the list of transaction branches that are currently in prepared or heuristically completed states.

Parameters:

flag - One of TMSTARTRSCAN, TMENDRSCAN, TMNOFLAGS. TMNOFLAGS must be used when no other flags are set in flags.

Returns:

The resource manager returns zero or more XIDs for the transaction branches that are currently in a prepared or heuristically completed state. If an error occurs during the operation, the resource manager should raise the appropriate XAException.

Throws:

oracle.jdbc.xa.XAException - An error has occurred. Possible values are XAER_RMERR, XAER_RMFAIL, XAER_INVAL, and XAER_PROTO.

getTransactionTimeout

public int getTransactionTimeout()
                          throws oracle.jdbc.xa.XAException

Obtain the current transaction timeout value set for this XAResource instance. If XAResource.setTransactionTimeout was not use prior to invoking this method, the return value is the default timeout set fo the resource manager; otherwise, the value used in the previous setTransactionTimeout call is returned.

Returns:

the transaction timeout value in seconds.

Throws:

oracle.jdbc.xa.XAException - - An error has occurred. Possible exception values are XAER_RMERR, XAER_RMFAIL.

isSameRM

public boolean isSameRM(javax.transaction.xa.XAResource xares)
                 throws oracle.jdbc.xa.XAException

This method is called to determine if the resource manager instance represented by the target object is the same as the resouce manager instance represented by the parameter xares.

Parameters:

xares - - An XAResource object whose resource manager instance is to be compared with the resource manager instance of the target object.

Returns:

true if it's the same RM instance; otherwise false.

Throws:

oracle.jdbc.xa.XAException - - An error has occurred. Possible exception values are XAER_RMERR, XAER_RMFAIL.

setTransactionTimeout

public boolean setTransactionTimeout(int seconds)
                              throws oracle.jdbc.xa.XAException

Set the current transaction timeout value for this XAResource instance. Once set, this timeout value is effective until setTransactionTimeout is invoked again with a different value. To reset the timeout value to the default value used by the resource manager, set the value to zero. If the timeout operation is performed successfully, the method returns true; otherwise false. If a resource manager does not support transaction timeout value to be set explicitly, this method returns false.

Parameters:

the - - transaction timeout value in seconds.

Throws:

oracle.jdbc.xa.XAException - - An error has occurred. Possible exception values are XAER_RMERR, XAER_RMFAIL, or XAER_INVAL.
