Method Detail

recoverable

public int recoverable()

If we don't have an XAResource then we cannot recover at this stage. The XAResource will have to be provided for us and then we can retry. Because recovery happens periodically, it is possible that it takes a snapshot of a transaction that is still running and will vanish from the log anyway. If that happens, then we don't need to (and can't) run recovery on it.

recover

public int recover()

Attempt the recovery. Return one of the status values above.

getXid

public javax.transaction.xa.Xid getXid()

Returns:

the Xid that was used to manipulate this state.

get_uid

public Uid get_uid()

Returns:

the Uid for this instance.

type

public java.lang.String type()

Returns:

the type for this instance.
