To answer your first question, the following xquery script won't touch
your D-Node(s):
xquery version "1.0-ml";
<p>the time is now { fn:current-dateTime() }</p>
<p>this is running on a { xdmp:platform() } platform</p>
I'm not an authority on the matter, so confirmation would be nice.
Cheers,

Hi ,
I have a few questions:
1) What is the *difference between eNode and dNode*? I have read that
E-nodes are required to evaluate XQuery programs, XCC/XDBC requests,
WebDAV requests, and other server requests.and dNodes are those which
directly talks with the database/forest. It is also told that if the
request does not need any forest data to complete, then an e-node
request is evaluated entirely on the e-node. I do not understand how
this is possible!! If eNode is meant for XQuery evaluation and XQuery
needs an XML to process, then every eNode request should talk to dNode.
Is there any caching mechanism? It will be great if anybody can explain
this to me?
2) There are two failover mechanism explained in the documentation.
Forest level failover and eNode level failover. It seems that forest
data level failover is not handled by Marklogic. Like if the filesystem
crashes, is there anyway by which Marklogic server *replicates the
forest to other hosts in same or different cluster*? If this feature is
not presently supported, then when can we expect this on the roadmap?
Thanks in advance.
regards,
Saptarshi
