<para>You must have DBA privileges to run that function.</para>
<para>
This function disconnects all the idle opened connections to a VDB datasource.
If there are active transactions server-side, using connections to that datasource,
they are not closed. After they finish, this function can be called again to disconnect
the new idle connections.
</para>
<para>
The datasource continues to be valid and any subsequent transactions using this datasource
will open a new connection to it.
