    • start

      public void start(Xid xid, int flags) throws XAException
      Starts work on behalf of a transaction branch specified in xid. If TMJOIN is specified, the start applies to joining a transaction previously seen by the resource manager. If TMRESUME is specified, the start applies to resuming a suspended transaction specified in the parameter xid. If neither TMJOIN nor TMRESUME is specified and the transaction specified by xid has previously been seen by the resource manager, the resource manager throws the XAException exception with XAER_DUPID error code.
      Specified by:
      start in interface XAResource
      Parameters:
      xid - A global transaction identifier to be associated with the resource.
      flags - One of TMNOFLAGS, TMJOIN, or TMRESUME.
      Throws:
      XAException

    • end

      public void end(Xid xid, int flags) throws XAException
      Disassociate the transaction (identified by xid) from the resource Ends the work performed on behalf of a transaction branch. The resource manager disassociates the XA resource from the transaction branch specified and lets the transaction complete. If TMSUSPEND is specified in the flags, the transaction branch is temporarily suspended in an incomplete state. The transaction context is in a suspended state and must be resumed via the start method 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 XAResource
      Parameters:
      xid - A global transaction identifier that is the same as the identifier used previously in the start method.
      flags - One of TMSUCCESS, TMFAIL, or TMSUSPEND.
      Throws:
      XAException

    • rollback

      public void rollback(Xid xid) throws XAException
      Specified by:
      rollback in interface XAResource
      Throws:
      XAException

    • prepare

      public int prepare(Xid xid) throws XAException
      Ask the resource manager to prepare for a transaction commit of the transaction specified in xid.
      Specified by:
      prepare in interface XAResource
      Parameters:
      xid - The global transaction identifier to assign to the prepared commit.
      Returns:
      A value indicating the resource manager's vote on the outcome of the transaction. The possible values are: XA_RDONLY or XA_OK. If the resource manager wants to roll back the transaction, it should do so by raising an appropriate XAException in the prepare method.
      Throws:
      XAException - An error has occurred. Possible exception values are: XA_RB*, XAER_RMERR, XAER_RMFAIL, XAER_NOTA, XAER_INVAL, or XAER_PROTO.

    • commit

      public void commit(Xid xid, boolean onePhase) throws XAException
      Specified by:
      commit in interface XAResource
      Throws:
      XAException

    • forget

      public void forget(Xid xid) throws XAException
      Specified by:
      forget in interface XAResource
      Throws:
      XAException

    • isSameRM

      public boolean isSameRM(XAResource xares) throws XAException
      This method must return true if xares and 'this' correspond to the same repository, regardless of how the connection is made or who is accessing. We compare storeIDs to make that determination.
      Specified by:
      isSameRM in interface XAResource
      Parameters:
      xares - The XAResource to compare with.
      Returns:
      true if xares and 'this' correspond to the same repository, regardless of how the connection is made or who is accessing.
      Throws:
      XAException

    • recover

      public Xid[] recover(int flag) throws XAException
      Obtains 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 XAResource
      Parameters:
      flag - One of TMSTARTRSCAN, TMENDRSCAN, TMNOFLAGS. TMNOFLAGS must be used when no other flags are set in the parameter.
      Returns:
      An array of zero or more XIDs of the transaction branches that are currently in a prepared or heuristically completed state. If an error occurs during the operation, the resource manager should throw the appropriate XAException.
      Throws:
      XAException - An error has occurred. Possible values are XAER_RMERR, XAER_RMFAIL, XAER_INVAL, and XAER_PROTO.
