Objectivity Expands Redundancy Options for Telecom
Applications with

Objectivity/DB Hot Failover


- Objectivity Adds to Fault Tolerance and Data Replication Options to

Objectivity/DB Providing More Choices to Achieve Five 9s (99.999% Uptime)
- 



MOUNTAIN VIEW, Calif., (September 20, 1999) - - - Objectivity, Inc., 
the leading provider of distributed, scalable object databases, today 
announced the immediate availability of Objectivity/DB Hot Failover, a new
option that provides support for the types of redundant processors, which
are common in telecommunications applications.

The Objectivity/DB Hot Failover option provides database redundancy between
two machines.  It is a perfect fit for the 2-machine types of
architectures found in high-availability telecommunications
applications such as network management, PBX and computer telephony.
With Objectivity/DB Hot Failover, the loss of one machine will go unnoticed 
by applications and all databases will be resynchronized after
re-connection of the failed machine.  The new option is a 2-machine
extension to the functionality currently provided to networks of three or
more computers by Objectivity's Fault Tolerance and Data Replication options.  


Objectivity's unique Data Replication option uses synchronous replication
techniques to guarantee that all on-line copies of the database are
identical. Continuous database availability is then ensured with a failover
transfer mechanism that allows the application to continue to operate
despite the failure of one of the database replicas. When the database
replica comes back on-line, it is automatically resynchronized.


Objectivity is a leading provider of object storage technology to the
telecommunications market.  Objectivity/DB is presently used by
telecommunications industry leaders including Ascom, Ericsson, Hekimian,
Marconi, Motorola, Nortel and Siemens, among others worldwide.

 

"We developed the Objectivity/DB Hot Failover option to provide flexibility
for our customers needing redundancy in smaller configurations," said David
I. Caplan, president and CEO of Objectivity.  He added, "Objectivity/DB now
offers our customers the ability to build high-availability
telecommunications applications for 2-machine architectures."
