Constructor Detail

NetXAResource

public NetXAResource(javax.sql.XAConnection xaconn,
                     int rmId,
                     java.lang.String userId,
                     java.lang.String password,
                     NetXAConnection conn)

Method Detail

commit

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

Specified by:

commit in interface javax.transaction.xa.XAResource

---

end

public void end(javax.transaction.xa.Xid xid,
                int flags)
         throws javax.transaction.xa.XAException

Ends the work performed on behalf of a transaction branch. The resource manager dissociates the XA resource from the transaction branch specified and let the transaction be completed.

If TMSUSPEND is specified in flags, the transaction branch is temporarily suspended in incomplete state. The transaction context is in suspened state and must be resumed via start with TMRESUME specified.

If TMFAIL is specified, the portion of work has failed. The resource manager may mark the transaction as rollback-only

If TMSUCCESS is specified, the portion of work has completed successfully.

Specified by:

end in interface javax.transaction.xa.XAResource

---

forget

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

Tell the resource manager to forget about a heuristically (MANUALLY) completed transaction branch.

Specified by:

forget in interface javax.transaction.xa.XAResource

---

getTransactionTimeout

public int getTransactionTimeout()
                          throws javax.transaction.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 for the resource manager; otherwise, the value used in the previous setTransactionTimeout call is returned.

Specified by:

getTransactionTimeout in interface javax.transaction.xa.XAResource

---

prepare

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

Ask the resource manager to prepare for a transaction commit of the transaction specified in xid.

Specified by:

prepare in interface javax.transaction.xa.XAResource

---

recover

public javax.transaction.xa.Xid[] recover(int flag)
                                   throws javax.transaction.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.

Specified by:

recover in interface javax.transaction.xa.XAResource

---

rollback

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

Inform the resource manager to roll back work done on behalf of a transaction branch

Specified by:

rollback in interface javax.transaction.xa.XAResource

---

setTransactionTimeout

public boolean setTransactionTimeout(int seconds)
                              throws javax.transaction.xa.XAException

Set the current transaction timeout value for this XAResource instance. This value overwrites the default transaction timeout value in the resource manager. The newly assigned timeout value is effective for the life of this XAResource instance unless a new value is set.

Specified by:

setTransactionTimeout in interface javax.transaction.xa.XAResource

---

start

public void start(javax.transaction.xa.Xid xid,
                  int flags)
           throws javax.transaction.xa.XAException

Start work on behalf of a transaction branch specified in xid

Specified by:

start in interface javax.transaction.xa.XAResource

---

throwXAException

protected void throwXAException(int rc)
                         throws javax.transaction.xa.XAException

---

getXAExceptionText

private java.lang.String getXAExceptionText(int rc)

---

throwXAException

protected void throwXAException(int rc,
                                boolean resetFlag)
                         throws javax.transaction.xa.XAException

---

setXaStateForXAException

private void setXaStateForXAException(int rc)

Reset the transaction branch association state to XA_T0_NOT_ASSOCIATED for XAER_RM* and XA_RB* Exceptions. All other exeptions leave the state unchanged

---

isSameRM

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

Specified by:

isSameRM in interface javax.transaction.xa.XAResource

---
