A service instance is a container for all OBIEE metadata (repository data, presentation catalog, security policy)
You manage a service instance in an BI domain using WebLogic Scripting Tool (WLST)
ssi
There is no special configuration but you can found the definition at the root location. The service instance as:
<service-instance>
<key>ssi</key>
<description>Default BI Service Instance</description>
<service-owners>
<service-owner>weblogic</service-owner>
</service-owners>
<modified>2018-02-08T13:21:23.480+01:00</modified>
<properties/>
<stores/>
</service-instance>
The service instance key can be found:
With wlst:
domainHome='F:\\Oracle\\Middleware\\Fmw\\user_projects\\domains\\bi'
listBIServiceInstances(domainHome)
INFO: Service Instance retrieved from the environment is ServiceInstance [
description = Default BI Service Instance,
key = ssi,
path = service_instances\ssi\metadata,
]
You can backup a BI Service Instance into a BAR file, and subsequently restore it either to the existing service instance running in the BI domain, or into a different service instance running on a different BI installation.
