 Continuent Ships New uni/cluster for PostgreSQL  

Continuent uni/cluster Solution Provides Enterprises Running PostgreSQL 7.4, 8.0 and 8.1 with Advanced Database Replication, Load-Balancing and High Availability for Mission-Critical Applications  

 San Jose, Calif. – September 8, 2006   – – Continuent, Inc., the leading provider of commercial open source middleware solutions for database high availability, today announced a new release of its LinuxWorld awarded PostgreSQL dedicated solution; Continuent™ uni/cluster for PostgreSQL, aka Continuent p/cluster 2006.

Continuent uni/cluster for PostgreSQL is part of a suite of Continuent products that deliver high availability for virtually any database environment.

This newest version of Continuent's uni/cluster software provides the highest levels of availability and scalability for applications built using the PostgreSQL database, and includes support for PostgreSQL 7.4, and PostgreSQL 8.x on most platforms. 

Continuent uni/cluster for PostgreSQL offers a multi-master approach to replication. Data is committed and available to all nodes in the cluster simultaneously, effectively eliminating data latency. The elimination of data latency also allows uni/cluster to offer more effective load balancing because any database server can be used to process user queries. 

"With Continuent uni/cluster for PostgreSQL organizations have insurance against outgrowing the capacity of their system,“ said Eero Teerikorpi, Continuent CEO.  "They can add new database servers on the fly and take advantage of p/cluster’s highly efficient load balancing, where database activity is directed to the least busy server.  This can be vital to maintaining continuous data availability for maximum productivity and to meeting customer expectations."

 “In the PostgreSQL community, there's a burgeoning demand to push both performance and reliability to higher and higher levels, using commodity hardware and reasonably priced and/or open source software tools" said Josh Berkus, a member of PostgreSQL's Core Team. "Clustering tools like Continuent p/cluster and Sequoia help raise high availability expectations of PostgreSQL users."

New features in Continuent uni/cluster for PostgreSQL include: 

1.  Support for PostgreSQL 8.1:  Continuent uni/cluster now supports PostgreSQL versions from 7.4 to latest 8.1, allowing scalable performance and fully supports complex queries with near-linear scalability.

2.  Support for fast, fully automated failover:  Continuent uni/cluster for PostgreSQL fully supports sub-second, transparent failover including re-start of transactions.  This brings the highest level of availability to the PostgreSQL market.

3.  Support for databases running on heterogeneous computers and at various version levels:  Continuent uni/cluster for PostgreSQL solves the upgrade problem. There is no need to have all databases at the same version level or even running on the identical hardware.  This preserves investments in existing hardware and software.

4.  Support for online maintenance:  Continuent uni/cluster for PostgreSQL allows machines to be added to or removed from the cluster real-time without any need to take the system down.  This is an improvement over other industry solutions that require the entire system to be taken out of service in order to add another node.
