<DIV><SPAN><FONT face=Arial size=2>Hi all,</FONT></SPAN></DIV>
<DIV><SPAN><FONT face=Arial size=2></FONT></SPAN> </DIV>
<DIV><SPAN><FONT face=Arial size=2>Is it possible to have two nodes with each
node containing a RAM copy AND and DISK copy?</FONT></SPAN></DIV>
<DIV><SPAN><FONT face=Arial size=2></FONT></SPAN> </DIV>
<DIV><SPAN><FONT face=Arial size=2>I am thinking a command such

]).</FONT></SPAN></DIV>
<DIV><SPAN><FONT face=Arial size=2></FONT></SPAN> </DIV>
<DIV><SPAN><FONT face=Arial size=2>Would this
work?</FONT></SPAN></DIV></DIV></BLOCKQUOTE>
<DIV><BR>There is no need to do that. A copy of disc_copies table is also stored
in RAM.<BR> <BR></DIV>

<DIV><BR>I don't think so. Out of curiosity, why would you want to do that?
