Hi All,
I think it is possible to setup the load-balancing as well as High
availablilty on Linux platforms.
Today, I installed IPVS and Heartbeat packages for Linux and gone through
100s of articles on internet to finally implement load balancing via Redhat
software itself. This is something called as Linux Virtual Server
implementation that uses common Virtual IP address as single access-point to
the Applications.
So effectively, I'll be using only 2 nodes and no additional hardware to
implement load balancing for internet (external) users of Oracle Apps.
On most articles, they mentioned a use of separate server (or 2 of them) to
act as Director and route the requests to one of the real servers, but I
modified the approach for my case and I'm using the same servers as
Director, internally routing the request to the real servers amongst
themselves. Also, I verified the failover works just fine with heartbeat
functionality in place.
So far it looks good. Will see what more roadblocks come in as I move
further.
Thanks for all the inputs so far and keep sharing.
Cheers,
Priyank.
