Hello,
I have a customer who is planning to deploy an application to run their
business which uses Informix as the underlying database. They have
roughly 1800 users and need a configuration which provides a fairly
high level of failover capability.
I've read through a considerable amount of Informix product info but
have some conserns about Informix ODS capabilities in terms of failover
and performance for our planned configuration.
The primary question I have is this: Is Informix CDR (Continuous Data
Replication) a viable method of creating a high availability
environment? Anyone have any experience with this and/or customer
references?
The customer has two data centers with high spped links between them
and has specified the requirement for a production database server
one datacenter with a backup server (mirror) in a secondary data center.
Can CDR be used to maintain a mirror copy of the data, and in the event
of one system failing what is the process for the other machine to
continue database operations ?
Any info or pointers would be appreciated. I've checked the Informix
web page - but not haven't found much useful detail there...
inthanksadvance,
Duane

There is an Informix White Paper describing Continuous Data Replication See http://www.informix.com/informix/corpinfo/zines/whitpprs/datarep/datarep.htm Francoise | |||||

I know of at least one large account team who have presented CDR as a
high-availability solution, with Informix account team support, so it
seems like a viable configuration.
If your customer doesn't like CDR, there is the EMC benchmark
demonstration of last May, where EMC storage hardware failover was
demonstrated on 8400s with an early version of 7.20; 58,000 outstanding
transactions were rolled back and the alternate server made available
within eight minutes. See note 170.
