We have 10+ Zope (version 2.7) servers ( on different machines). Right now each Zope server independently handles session management which means that if a Zope server fails the users on that Zope server do not get redirected to a functioning Zope server but get "stuck" on the failed Zope server. Is there any way to manage the session of all the zopes servers in a common place.
If you have only a moderate number of sessions, you can store the session storage on the ZEO server. If you use buildout you'd do something like: [zeo] recipe = plone.recipe.zeoserver ... zeo-conf-additional = %import tempstorage <temporarystorage temp> name temp storage for sessioning </temporarystorage> [instance1] recipe = plone.recipe.zope2instance ... zodb-temporary-storage = <zodb_db temporary> mount-point /temp_folder <zeoclient> server 10.0.0.1:8100 storage temp name zeo-temp-storage </zeoclient> </zodb_db> The config is the same if you just put these straight into zope.conf and zeo.conf. Zope 2's built-in session machinery should handle a couple dozen sessions at a time. Once you go beyond that look at Beaker (via collective.beaker) and memcached as a backend. This does apply to the currently supported Zope 2 versions (2.12 & 2.13). I have no idea what of this works in the ancient 2.7. Hanno
