Oracle Fusion Middleware

When dealing with large amount of instances (on one composite application or more), you can end up with slow performance
on the instances load.

I will describe, how a simple configuration can increase the performance for this issue.

Before, I would like to emphasize: performance issues on EM, can be caused from many reasons, like – wrong process plan, DB growth, lack of infra structure resources etc.
When planning processes, there is a need to take in a consideration, all of the parameters.

So, how to set those parameters – very simple:

Go to EM – Right click on soa-infra->SOA Administration->Common Properties:
Under Data Display Options mark the 2 check boxes:

Disable fetching of instance and fault count metrics. Each metric can still be retrieved on demand

Set default search criteria to fetch recent instances and faults only within a recent duration (applies to lists of instances and faults) – the default value is 24H’, and you can change it according to your needs

The results will cause:

1. No instances will be shown on the Dashboard.
   What you can see, is the summary for the instances
     
2. Under the instances tab you will automatically find only instances from the last 24H (as defined is the second checkbox)
   

Good Luck
