Hi Patrick,
I run a HA(High Availability) technique that I developed myself whereas 2 servers are redundant syncing up bout every 15-20 seconds. Basically mine is IP oriented instead of machine oriented...either machine can be the master and will stay the master until the slave deems the master as having problems and not being able to handle the server responsibilities. When the slave decides this, it then grabs the roaming IP and turns on the servers and it is then the master.
If a redundant HA server is machine oriented, that means that, yes, the slave will take over but as soon as the master comes back on line, the master takes back the roaming ip and starts up the servers and the slave machine will assume slave responsibilities again.
these are just some ideas of what you are looking for. Also, google around using High Availability as a keyword...a bunch out there I think, I am just about to the point to start building up my web-site where I will cover my system in depth.
Incidently, over the last month or so, the main server seems to loose it and decides to reboot in which case, the slave takes over...I have never been around when it actually happened and sometimes I never even realized it for a day or so. It's kinda seamless and the switch takes bout 20 seconds. My point, I do know it works as it should!
Hi John,
Thanks for your suggestion. The 20 seconds is a bit long for the telco service being out of order but I will further investigate the HA stuff over at linux-ha.org to see if it can be tweaked.
Regards, Patrick
I hear ya Patrick, the only reason it is bout 20 secs is because I cannot just flush the cache in this bs zoom router...I have to reboot it in the code...if I had a router that I could flush the cache I could do it in about 5-6 secs which is much better but, hey, I don't really need it, I don't have bunches goin on and I just do it to do it.
