An Oracle 11i DBA in South Carolina, USA.
This blog will likely focus mainly on Oracle, with a few diversions as I see fit. I would describe myself as a healthy skeptic and realist in regard to Oracle products.
Interestingly, it can also serve as a nice place to send friends and relatives when they really want to know what I do at work. (And why I’m no expert at XP problems!)
My Oracle landscape looks like this, for a total of 19 instances on 8 nodes:
- Oracle Apps 11.5.10.2 with RDBMS 11.1.0.7 on Red Hat 5.3 Linux (x86-64) utilizing Dataguard over WAN as disaster recovery insurance (Database nodes are physical machines, the applications tier is a VMWare virtual machine)
- Development, Regression Testing, Training, Sandbox and Audit versions of the 11i environment (all nodes are VMWare virtual machines)
- A handful of standalone Oracle databases (10.2 – 11.2) on Red Hat 5.3 Linux (x86-64) running disparate applications. One of these runs on 32-bit Windows, due to 3rd party vendor constraints (all VMWare virtual machines)
- Oracle Enterprise Manager 10.2.0.5 with RDBMS 11.2 (yes, I know, not certified) on Red Hat 5.3 Linux (x86-64) with Diagnostics and Tuning packs.
- Discoverer 10g (10.1.2.3) co-located on the 11i Applications Tier VM.
- RMAN backups for everything, orchestrated out of EM 10.2.0.5.
