I thought it might be out of my league. We'll come up with another option. Thanks for your comments and suggestions. ~Shane

In short, it is not recommended but it is possible. A better solution is to have 2 different computers, or if you are upgrading an application, just (after testing and backing up) upgrade to 4.x (for example, 3.2.11 > 4.0-7 > 4.1-5). Here are some of the reasons/gotchas as to why it is not recommended. You need: * different port numbers on each instance for the Admin Interface (8001 by default) and for xdqp (7999 by default) * different data directories * different MarkLogic installation directories * different startup scripts * you will have to do your own installation for the 2nd installation to change the above things * upgrades will be problematic and manual * all of the cache setting defaults assume that MarkLogic has access to the whole machine * perhaps a few things that I have not thought of I definitely recommend against trying this. -Danny From: [email protected] [mailto:[email protected]] On Behalf Of Strawn, M.

Quick question re: running two instances of MarkLogic on one host: 1) is it possible? 2) if so what are the big issues/gotchas if any? 3) if you're thinking "why would you want to do that?" then what's a better solution, assuming: * you may want different versions of ML (v3 vs. v4) * when the taskserver stops, the other taskserver keeps on trucking - perhaps in v4 the taskserver is not so difficult to resurrect?
