Hi,

Can anyone help with some obvious issues around setting up a load balanced
OTRS?

- Does last db write always win?
  I imagine there's no built in protection against it.

- Are HTTP sticky sessions required and if so, how can they be configured?
  I imagine OTRS needs some built in support to allow identification of
user sessions in the balancer so that it maps them on the same app server.

- To what extent is shared storage required?
  An older mailing list message proposes sharing the whole /var dir through
a storage that support file locks (mainly to safely use TicketCounter.log
but this could be worked around by setting up different SystemIDs (via
SysConfig) on each app server). While sharing storage is required for
/var/article (when attachments are stored on disk) I don't know if it's
required or even safe for the other subfolders in /var (especially /tmp).

Thanks,
Bogdan
