I'm a newbie to Oracle database administration and I've been recently tasked to upgrade our databases in our development environment from 10g2 to 10g4.
The databases are housed on SUN servers (there are several database servers), running with RedHat Linux 4.5 operating system. Additionally, the Database servers run either in 64 or 32 bit mode.
The Architecture of our environment also includes Oracle OAS.
My question is, where can I find documentation (or guidance in this forum) to apply the upgrade to the Database Servers, and will I also have to upgrade OAS as well?
Thanks in advance
