An idea is that we'd have a bigish LDOM for logins and apache (because we want users to be able to log into the WWW machine), another for MySQL, another for secondary LDAP, and another for maybe jakarta/tomcat/glassfish/whatever java webapp server we end up using. The LDAP and MySQL ones would obviously be smaller than the Apache and login one.
Myself and Cian have been talking about this a bit more, and we're thinking that containers might be more appropiate than LDOMS for this. As the LDOMS all have seperate kernels etc. there's a much larger amount of work involved in keeping the thing up to date etc. I'm just not convinced that it's worth that. The LDOMS do give us a greater amount of seperation and isolation, but realistically if apache goes nuts and crashes it's server very few people will be worrying about databases potentially dying. The added bonus of this approach is we would be able to downgrade the firmware on Murphy, as the most recent version (needed for LDOMs) has caused the cdrom drive to disappear :/ a. -- Andrew Harford System Administrator, DCU Networking Society Ordinary Member, Societies & Publications Committee I'm a man who discovered the wheel and built the Eiffel Tower out of metal and brawn.
