public void setSnapshot(boolean&nbsp;snapshot)</PRE>
<DL>
<DD>This transaction will execute with snapshot isolation. For databases
 configured with <A HREF="../../../com/sleepycat/db/DatabaseConfig.html#setMultiversion(boolean)"><CODE>DatabaseConfig.setMultiversion(boolean)</CODE></A>, data values
 will be read as they are when the transaction begins, without taking
 read locks.
 
 Updates operations performed in the transaction will cause a
 <A HREF="../../../com/sleepycat/db/DeadlockException.html" title="class in com.sleepycat.db"><CODE>DeadlockException</CODE></A> to be thrown if data is modified
 between reading and writing it.

<PRE>
public void setSync(boolean&nbsp;sync)</PRE>
<DL>
<DD>Configure the transaction to write and synchronously flush the log
 it when commits.
 
 This behavior may be set for a database environment using the
 Environment.setMutableConfig method. Any value specified to this
 method overrides that setting.
 
 The default is false for this class and true for the database
 environment.
 
 If true is passed to both setSync and setNoSync, setSync will take
 precedence.

<DT>Parameters:<DD><CODE>writeNoSync</CODE> - If true, transactions exhibit the ACI (atomicity, consistency, and
 isolation) properties, but not D (durability); that is, database
 integrity will be maintained, but if the operating system
 fails, it is possible some number of the most recently committed
 transactions may be undone during recovery. The number of
 transactions at risk is governed by how often the operating system
 flushes dirty buffers to disk, and how often the log is
 checkpointed.</DL>
