Identify two accurate descriptions about managing multiple instances of each adapter in the runtime.

Each JCA adapter has a single deployment listed in the WLS Console. Identify two accurate
descriptions about managing multiple instances of each adapter in the runtime.

A.
Instance configuration in the SOA Suite deployment plan

B.
JCA tiles for each adapter instance

C.
Adapter connection factories specified in the WLS Console

D.
One entry per adapter instance in the adapters_config.xml file

Explanation:

*The Oracle Database Adapter is a JCA 1.5 connector, which is deployed to the application server
during installation.
The Oracle Database Adapter consists of multiple instances; each instance represents a
connection to a database end point. Different SOA processes may point to the same adapter
instance (database), while different service endpoints in a SOA process may point to different
adapter instances (databases).
Because each adapter instance points to a single database, there is a one-to-one correspondence
from adapter instances to application server data sources. Out of the box there is a single Oracle
Database Adapter instance named eis/DB/SOADemo, which points to the data source
jdbc/SOADataSource.
The list of adapter instances is stored in a deployment descriptor file, weblogic-ra.xml on Oracle

WebLogic Server. (It is inside of DbAdapter.rar, which contains also the Java class files in
DBAdapter.jar). Configuring an Oracle Database Adapter instance is more about creating the
underlying data source: getting the correct JDBC driver and connection URL.
