Mistake #1 Success Criteria

How are we getting on

installing OEM?I’ve nearly

rolled out all the agents

Great, when will it be

complete?

Not sure, soon hopefully, got it

on the back burner

Mistake #1 Success Criteria

1# Oracle Enterprise Manager is an ‘ENTERPRISE’ application

2# It’s a critical part of your infrastructure

3# It’s designed to HELP you manage your estate

4# Oracle Enterprise Manager isn’t a glorified db console

5# Why isn’t success criteria defined?

6# IT Manager shouldn’t see this as ‘just’ a job for a DBA

Mistake #2 Partial Configuration

We’re getting quite a few alerts

from OEM

Yeah, no worries because I’ve got a

email filter on them

What about the critical alerts We still getting the

old alerts through the scripts so it’s

fine

Mistake #2 Partial Configuration

1# It’s way tooooooooooooooo easy to install OEM

2# The implementation doesn’t cover any configuration

4# We create our own email spam

3# Configuration is only done to resolve ‘issues’

Mistake #3 Feature Utilisation

Have we deployed all the latest monitoring templates?

Not yet, it takes ages and it’s really slow, you need to

go into each….

Ok, when do you think you can get prod done by??

it’s on the to do list but haven’t got around to it

yet, soon…

Mistake #3 Feature Utilisation

1# Oracle Enterprise Manager enables you to….

Ok….lets calm down a bit….

Successful Implementation

Agent Rollout

Target Properties

Credentials

Rollout

Templates

Incident Rules

Planning

This is generic WORK OUT WHAT YOU WANT OUT OF OEM and then plan accordingly
