Extra redundancy

[JLW]

Hi,

A few questions:

1. Is it possible to mirror a live Revive AdServer installation?

2. How do you backup / restore a Revive Adserver?

Many thanks,

Jason

1. Yes. It's definitely possible to have multiple servers with the same Revive Adserver code on them, all using a central DB.

2. It's simply a case of backing up the installed code, and the database.

What happens with the cron job? Should it be on all the php nodes or just 1 or does it handle multiple crons going off on multiple servers?

Thanks

The maintenance process does have locking in place, to ensure that only once instance is triggered at a time, but personally, whenever I was managing a setup like that, I would put the Revive Adserver code on the central DB server too (even though it would not serve ads from there), and then run maintenance on that machine, so that there's no need for network traffic off-server to run maintenance.

Every millisecond counts, right? ?

Thanks for the speedy reply!

Yeah we make heavy use of AWS and RDS so sadly cant put the code on the DB server but I always meant to double check for scaling purposes if the task could lock as most of the php nodes would just be exact mirrors.

I may spin a low end box up to handle the tasks but if I at least know it works as a mirrored then I can get under way with scaling anyway.
