On Sunday, the first day at Oracle Open World in San Francisco, Andreas Ellerhoff, the lead DBA of Deutsche Messe (German Trade Fair), the largest trade fair organization in the world, did his excellent presentation on the project “Move from failover clusters to RAC – and upgrade to Oracle Database 18.104.22.168 introducing Data Guard and ASM as well”. Deutsche Messe is an official Oracle Database 11g Reference customer.
The presentation was well attended. And the project itself is quite interesting as Deutsche Messe upgraded in 2009 the system to order space and equipment for trade fairs online and the system where they run CeBIT, the largest computer trade fair worldwide on. In this 30 minute presentation the whole project from taking the decisions for hardware and software to setting up the extended RAC, upgrading from 10.2.0.3 to 11.1.0. and later to 22.214.171.124 with PSUs and introducing Data Guard‘s snapshot standby technology got covered.
