Let's begin to understand the core concepts and usage of ESS functions through a series of real-life examples. For an Oracle SOA Suite 12c environment to be performant, the dehydration data store needs to be optimized by ensuring that it is cleaned up periodically. Thus, imagine that as an Oracle SOA Suite 12c administrator you want to create a schedule to perform a very important administration activity: purging completed instances.

Conceptualize the illustration depicted in the following figure. Here, we have a simple composite that invokes the delete_instances_auto procedure in the SOA package under the soa_infra schema. This package expects a set of parameters that determine the purging behavior, such as minimum and maximum date ranges for instances to be deleted, their states, and retention period, to name a few. The composite exposes a one-way service endpoint that accepts these purging parameters as arguments, which would allow the auto purge package to be executed...
