Hi all,

I am currently working on a consolidation project. Within this project we want to consolidate Oracle schemas within Oracle 8.1.7.4/ 10g instances and Oracle instances on AIX 5.2 servers.

We see 3 potential problems:
1. How do we prevent instances and schema's influencing each others performance?
2. How do we determine which schemas can be consolidated within the same instance from a resource usage point of view? 3. How do we determine which instances can be consolidated on the same server from a resource usage point of view?

To address our first problem we are looking at the Oracle Resource Manager for controlling the resource usage of schemas within the same instance and AIX Workload Manager to control resource usage of instances on the same server.

For our second and third problem we want to create a shortlist of 3 (combination of) tools to evaluate which should be able to:
- Measure the usage of instance resources like buffer cache, redo/undo
blocks, open cursors etc. on a schema level.
- Measure the available instance resources within an instance

• Measure the usage of server resources (CPU, Memory, Disk IO, Network IO) on a schema level and on an instance level.
• Measure the available server resources within a server

Does anyone has an idea of which (combination of) tools I should put on this shortlist?

Thanks... Jaco
