Hi Stan, I don't think that this admin function is a so-called atomic function, so I would expect only one database.xml update per host, even for multiple attach-forest calls, as long as there are done in the same request/transaction. But even if it is atomic, then it *should* be atomic across the cluster. On the other hand, I am not a Mark Logic expert, so perhaps someone from Mark Logic cares to comment? Otherwise, send a message to [email protected]. By the way, the MarkLogic Server Admin site runs on plain Xquery as well. So you should be able to achieve exactly the same by calling those admin functions directly.
