(RADIATOR) RE: Redundancy for RADIUS

[Surajh Surjoo [ MTN - Innovation Centre ]]

yes.  GPRS has now become a carrier for many other services as MMS and WAP and thus needs to be given carrier grade service.
However, we thought of the an Oracle DB, but to use two of them is very expensive.

Hello Surajh -

This is a difficult problem with no single good answer.

How do people on the list provide redundancy?

My personal view is that a single "high-availability" database server 
is best, but then you are back in the situation of having a single 
point of failure.

regards

Hugh

NB: have you included a copy of your configuration file (no secrets),
together with a trace 4 debug showing what is happening?
