Are you asking about a single-instance cluster? That will make some difference.
In step (2), what happens when you get to Security and Schemas? If the admin API allows you to delete them, that will break the new instance. I think you could just skip that step, actually. The admin:save-configuration() call should just overwrite everything. How do you plan to evaluate the script in (3)? This is a bootstrap problem. I don't think you can solve it as simply as you might like, because a freshly-installed server doesn't have a packing mechanism or even an ad-hoc query interface. One possibility is to upload code into /opt/MarkLogic/Admin/myapp/ and then eval it with wget or curl. -- Mike On 24 Oct 2011, at 15:30 , Ford, Kevin wrote: > ML gurus, > > I'd like to back-up the settings for all databases, forests, and appservers > per ML server instance.
