Tungsten can replicate from MySQL to Oracle and vice versa

Continuent Tungsten is an open source stack for database scale-outvia economical software and commodity hardware. It providesdatabase replication, group communications wrappers, performancetesting tools and shared infrastructure required to build workablescale-out solutions. Tungsten includes sophisticated clustermanagement, based on group communications.

Continuent's Tungsten provides:
• Basic failure protection: maintain extra replicas in casethe master database fails, with automatic master failover bypromoting one of the slaves as a new master
• Performance: use database replicas to scale reads
• Cross-site clustering: maintain and replicate databases onmultiple sites for disaster recovery
• Heterogeneous data integration: replicate from MySQL toOracle and vice versa
• Populating a data warehouse: copy data from a productiondatabase into a replica for reporting purposes.

"The Tungsten stack is tremendously flexible," saidRobert Hodges, CTO, Continuent. "Gaining benefits requiressolving a number of difficult scale-out issues. There is no'one-size fits all' solution to database scale-out. You need to beable to flexibly combine and extend technologies to create workablesolutions."

An important principle of the Tungsten stack is that you canmix-and-match technologies as appropriate to any particularscale-out problem. For example, while proxying is critical for someapplications, they are an unacceptable performance drag for others.Tungsten users can apply proxying or not to suit the problem athand.

"For there to be increased adoption of open source databases at the enterprise application tier, a number of factors need to beaddressed," stated Matt Aslett, analyst, The 451 Group, atechnology industry analyst company focused on the business ofenterprise IT innovation, in his report. "These includeincreased enterprise functionality, improved service and supportoffering, proof that performance fears are misplaced, increasedresistance traditional database software licensing, and a move toweb-based architecture for internal applications."

"Continuent Tungsten is a very important database extension asit allows open source databases to support business criticalsolutions and provides a performance boost," says EeroTeerikorpi, CEO, Continuent. "Tungsten enables customers tostay on Oracle database without using costly Enterprise licenses.Because Tungsten can replicate from MySQL to Oracle and vice versa, it opens new avenues for open sourcedatabases in the enterprise application mix."
