Martin Klier, Performing Databases GmbH


 

Abstract

Sharing Experience from 24 Months of Database Upgrade and Migration Running out of support, security concerns, new features, coming operating system or hardware changes.... there is a long and versatile list of potential reasons for our customers, to change the version of their running Oracle Databases. The "choice" of situations, challenges and options for changing the version, is at least as long and as versatile as the reasons are. Oracle ACE Director Martin Klier will deliver an unveiled overview about his adventures with logical dependencies, human sensitivities, technical skulduggeries and license traps. All this happens, when one or multiple databases are to be migrated or upgraded to a new version in a controlled fashion. For A as in AIX, L like Linux, S like Solaris, V like Virtualization, W twice in Windows ... there was trouble, there was a solution, and there was a new experience!

For years now, Martin can be found speaking on topics regarding Oracle Core, Performance and High Availability¬Ě on various national and international conferences, like COLLABROATE (IOUG), Oracle Open World or DOAG Konferenz. Martin frequently blogs about recent issues and their solutions at http://www.usn-it.de and is known on Twitter as @MartinKlierDBA.
