[Spacewalk-list] HA Solution to Spacewalk

[Nelson Marques]

Hi,

Load Balancing should be with 'sticky sessions' and Tomcats need to be
clustered for session management (I'm not sure is the webapps play any role
on that, though someone can point it). That in theory should work. I'm
going for a similar architecture, though currently I'm struggling with
updating to SW2.1 (schema update).
