   Sets the module name for Oracle tracing.
  </para>
  <para>
   The module name is registered with the database when the next
   'round-trip' from PHP to the database occurs, typically when an SQL
   statement is executed.
  </para>
  <para>
   The name can subsequently be queried from database administration
   views such as <literal>V$SESSION</literal>.  It can be used for
   tracing and monitoring such as with <literal>V$SQLAREA</literal>
   and <literal>DBMS_MONITOR.SERV_MOD_ACT_STAT_ENABLE</literal>.
  </para>
  <para>
   The value may be retained across persistent connections.
