That’s what I figured—that it should start quickly and be immediately available, so if it’s not something must be wrong.

At the moment I’m just firing up basehttp using the built-in script, so no on-startup commands or job services (yet).

My guess is that I have a corrupt database or something but I thought there might also be some “recover from a bad shutdown” process that happens. Our validation reports are in a single database and each doc is around 40MB.

I dropped my validation report database and then BaseX was able to start as expected. Fortunately, we keep those reports in a git repo so there’s no loss if a database goes bad (and I’m not yet bothering to back up my databases).

I’m working now on setting up parallel servers so I can have one do the data processing while the other serves pages.

If I understand the docs around file locks and so on, it is safe to have databases shared between servers for read and as long as writes are done from the data processing server the page-serving server should be good.

Cheers,

E.

Usually, BaseX should be available immediately after startup.
How do you start BaseX? Have you enabled any services [1] that will
run at startup time, or similar?
