How to become an Oracle Apps DBA ??
To become a successful Oracle Applications DBA, one should have knowledge on both the database technologies as well as application technologies. Database technologies (such as Oracle RAC, Oracle ASM and Oracle DataGuard) and application technologies (such as Apache, 10g AS, Weblogic and OHS) as E-Business Suite has transformed from Apache to 10g AS and then to Weblogic in R12.2. If you know how load balancers work such as F5 or Oracle Traffic Direcotor, it will be an added advantage in desigining high available architectures of E-Business Suite with failover capabilities.
Pre-Requisites to learn E-Business Suite
Before learning Oracle E-Business Suite 12.2, one should be good in Linux administration, database administration (Oracle DBA) and Oracle Weblogic Administration as Oracle E-Business Suite R12.2 uses Weblogic as its Web Server and Application Server. Some companies may differentiate the roles between Oracle DBA, Oracle Apps DBA, and Weblogic Administration; but if you want to be a successful Oracle Apps DBA, you should be good at Applications, Database and Weblogic.
