If your application is not using that product, you can ignore this change. <p>Historically, the Berkeley DB <a href="../../api_c/db_cursor.html">DB->cursor</a> interface took the DB_RMW flag to indicate that the created cursor would be used for write operations on the database. This flag has been renamed to the <a href="../../api_c/db_cursor.html#DB_WRITECURSOR">DB_WRITECURSOR</a> flag. <p>The application should be searched for any occurrences of DB_RMW. For each of these, any that are arguments to the <a href="../../api_c/db_cursor.html">DB->cursor</a> function should be changed to pass in the <a href="../../api_c/db_cursor.html#DB_WRITECURSOR">DB_WRITECURSOR</a> flag instead. <table width="100%"><tr><td><br></td><td align=right><a href="../../ref/upgrade.3.0/txn_stat.html"><img src="../../images/prev.gif" alt="Prev"></a><a href="../../reftoc.html"><img src="../../images/ref.gif" alt="Ref"></a><a href="../../ref/upgrade.3.0/lock_notheld.html"><img src="../../images/next.gif" alt="Next"></a> </td></tr></table> <p><font size=1><a href="http://www.sleepycat.com">Copyright Sleepycat Software</a></font> </body> </html>
