Hi everybody.
I want to raise two CDO servers in failover configuration. Where can I find any instructions on that? Google doesn't know...

There's a standalone example for monitored fail-over clusters in the org.eclipse.emf.cdo.examples plugin.
Please have a look at org.eclipse.emf.cdo.examples.server.FailoverExample.Monitored

Does that help?

Cheers

Hello,

In Oxygen CDO SDK there is "org.eclipse.emf.cdo.examples.clone" and "org.eclipse.emf.cdo.examples.master". There is no reference to fail-over in these projects. I've found the fail-over example on GitHub - https://github.com/eclipse/cdo/tree/master/plugins/org.eclipse.emf.cdo.examples/src/org/eclipse/emf/cdo/examples/server.

Can you please let me know:
- Is the fail-over approach still viable? Online references which I found date back to circa 2011, including the previous post in this topic.
- Where can I find instructions how to set-up a fail-over server, similar to the "CDO Server Operator's guide"?
- Is the example still working?
- How mature is the fail-over feature? I.e. would it justify the effort investment to set it up to survive individual server patching/restart or it'd be easier just to live with several minutes of unavailability per month?

Thank you, Pavel.
