hot -Backup server solution
I want to setup a automatic failover server . We have installed RHEL 6.2 and running a ATM Sitching application , which is going to comnnect to multiple banks for ATM,POs,Deposit etc transactions .i am looking at deploying a backup server in a remote site , which is 20Km away . i want this server to switch over if the Main site fails .
Since it is a mission critical applicaton up to last minute data is required at both the sites .
Both the sites will be connected thru VSAT or Fiber cable .
Pls help me with a application which can do this .
