AW: Hardware requirements when migration oracle from NT to Linux

Hi Paul,

I know that my NT machine is not a high performance, optimal configrated oracle server, cause this server is also: Filesserver
Microsoft SQLServer
Centura SQLBase Server
PDC So, my developers are satisfied with performance yet. I do not want to migrate the hole machine to linux, I only want to migrate my oracle from NT to linux. So therefor I asked the list what hardware do I need to hit the same performance. Cause I migrate my oracle to another server, i will install 8.1.7 not 8.1.5.
We are talking about a developer machine, and about three instances with about 30 schemas, schemas use 20 to 500 MB tablespace. So it's NO production and the data to handle is very small.

Hope I can clarify my question.

There are some oracle dba's outside which handle "small" databases.

DBA/SysAdmin requirements when migrating oracle from NT to Linux might be a better topic for this list.

In the first place - your hardware configuration just plain sucks for NT. It will also suck for Linux, just less. Oracle on NT is far better off with a single, faster CPU than 2 slower CPUs. You have everything, including the OS, swap, oracle binaries, online redo, archived redo, rbs, temp, indexes and data on the same RAID 5 volume.
Do you typically configure file servers? Get yourself at least 4 distinct volumes on separate mount points on separate physical disks. Developer databases work just fine on a JBOD configuration.

Btw, you were expecting to compare 8.1.5/NT with 8.1.7/Linux? LOL.

let the flames begin.
