Configuring BigIP for REN server is not very complicated. There are just a few steps but you need to make sure you do it right. Troubleshooting becomes more difficult especially when you do not have access to BigIP.
My configuration:
2 web servers (Load balanced)
2 App Servers
We did not have a dedicated vip for REN server so we used the one that was load balancing web servers. This will slightly change the iRule. So, here are the steps
- Create Ren Server definitions in PeopleSoft for every app server running PSRENSRV
- Create cluster definitions in PeopleSoft for every REN server definition (in my case PSREN1 and PSREN2). I will not get into the pros
and cons of setting up multiple clusters or single cluster with multiple
members. In my experience I have found multiple clusters each with one
member to be better
- Set REN server browser URLto your vip:port
- Create an iRule in BigIP
when HTTP_REQUEST {
if {[HTTP::uri]
starts_with "/psren1"}{
node APPSRVR1 port
}
elseif {[HTTP::uri]
starts_with "/psren2"}{
node APPSRVR2 port
}
else {
"you would want to forward request to your web server pool if the request is not for PSREN1 or PREN2. You would not need this step here if you have a dedicated vip for ren server".
}
}
Clear App, Web, Process Scheduler cache and you are in business
