Hi Michael,<div>interesting point is mentioned in the restrictions:</div><div><br></div><div><meta charset="utf-8"><span class="Apple-style-span" style="font-family: 'Lucida Grande', Verdana, Arial, sans-serif; font-size: 13px; "><a name="N1000E"><ul style="padding-left: 1.5em; ">
<li>Only one cluster node writes to the repository. This means that the authoring environment is only accessible on one dedicated cluster node, which is called the <em>master</em> node. </li></ul></a></span></div><div><br>
</div><div>For the project I'm working for this is not a solution as each node must have write access to the repository as well as to the Lucene index.</div><div>This is what I wanted to highlight in today's workshop that Yanel/Yarep should come up with a concept of a single "write" instance which gets used by all members in the cluster so that writing is also possible for other nodes... to be continued....</div>
