[opencms-dev] HELP!!!! Can Opencms run in a set of servers?

[Arash Kaffamanesh]

Hi,

Why not setup a cluster (Tomcat-Cluster) of 10 servers?

Kind Regards,
Arash

It's a good question, and it has been asked several times, but I usually
without any answer. I think the simple answer is that out of the box,
this is not possible.

However I think it can be made to happen, but would take some
experimentation.

Here are some ideas: One possibility is to setup multiple instances of
OpenCms to read from the main database, via a username with read-only
access. Another possibility is to use database replication (I believe
most databases support this nowadays) so that each server will have it's
own local read-only copy. The static export directory could be a problem
-- the replicated servers will need to copy images into there when
things are published.

Another possibility is that if the site is all static, is to somehow
export the site into a file system and share it among the servers (eg
using networked file system or other means).

Maybe someone else has looked into this problem?

Joe.
