trol growth. Too much instance-related data requires additional storage and it
also impacts the performance of the console. We will discuss management of
the instance data in Chapter 8 , Managing the Metadata Services Repository and
Dehydration Store , but it may be worthwhile briefly describing how to delete in-
stances, thereby purging all data related to it, manually from Oracle Enterprise
Manager Fusion Middleware Control as part of composite management activit-
ies. Deleting instances is quite easy as demonstrated in the following steps:

1. On the navigator, expand Farm_[Domain] | SOA | soa-infra .

2. Expand the partition (for example, default) and click on the composite name

(for example, HelloWorld) .

3. Click on the Instances tab.

4. At this point, you can delete instances in one of the following two ways:

• Highlight the list of instances (press the Ctrl key and click on each com-

posite one by one) and click on the Delete Selected button.

• Click on the Delete With Options button. From here you can delete in-

stances older than a specific time or delete all instances within a time
frame that have a certain state.

We can also bulk delete/purge composite instances from the underlying data-
base dehydration store through the use of SQL scripts. Again, this will be
covered in more detail in Chapter 8 , Managing the Metadata Services Reposit-
ory and Dehydration Store .
