[SSI-users] OpenSSI Clustering Questions

[Christian K. <c....@do...>]

Hello,

=20

im quite new to openssi i stumbled upon it on freshmeat. I'm trying to
build up a cluster for 5 Services that currently run on a couple of
Machines ( mostly dual xeons but some p4 machines among them aswell)

=20

I checked upon the Mailinglist but couldn't find that much information
regarding my questions.

Main Service=20

Web-Server (Zeus) , Process list looks like that

When trying to loadbalance this between 3 Nodes how would it work ? each
of the root owned processes gets migrated on a machine or can I move
over the sub processes to another node ?=20

Like

=20

node1 contains root PID 10934

node2 contains root PID 10935

=20

Or can I even send over PID 32576 & 16894 to node1 and rest to node2

=20

mySQL

=20

Do I need to install the mySQL cluster or is openssi handling the
distribution of the processes among the nodes and therefore use of the
normal mySQL-server binarys is enough.

Sorry if these questions have already been answered but I was unable to
find sufficient answers on the mailing list nor on the wiki.
