restarting multiple web workers
Hi, I’m using the multiple web server stuff described here: https://wiki.galaxyproject.org/Admin/Config/Performance/Scaling that seems to address the responsiveness issues i see when many users are active. However, when i add a new tool - it does not alway show up (only for one of the workers maybe?) Right now I’m restarting, but this costs a minute or two of downtime as the server starts up. Has anyone experimented with rolling restarts of web server processes? Alternatively, has anyone found a good way to speed up the startup process? Thanks! Brad -- Bradley W.

I don't have good answers for the rest of your questions (I'm sure someone else can chime in), but I do have some information about this. You're correct in that, currently, the only process that will reflect the new or reloaded tool is the one the admin user was actually interacting with. While it doesn't solve your problem right now, I've been working on new mechanisms for reloading tools and generally interacting with multiple processes that will be available soon. -Dannon
Hi Brad I have a hacky shell script that I use to do rolling restarts of our local server: https://github.com/pjbriggs/galaxy-admin-utils/blob/master/rolling-restart.s... Generally it works okay here but you would have to check how it fits into your local setup. I can't guarantee that it's 100% robust. We have multiple web processes so the service appears to be uninterrupted, although obviously you can get anomalies e.g. when some web processes know about a new tool but others don't.
