<listitem>Remove all VSP and XSLT and other web resources from their

<listitem>If DB.DBA.VAD_UNINSTALL() succeeded the server comes back
on-line. If there was a failure in mid-uninstall, such as running out
of disk or some other serious unrecoverable database error, the server
exits. The failed uninstallation can be undone manually. As usual,
halting the server, deleting the transaction log file and restarting
will force the server to start from the checkpoint as if the
uninstallation was never attempted.</listitem>
