SOA Applications communicate with Database using DB Adapter. When SOA composites are deployed in weblogic server, they require Outbound connection pool to communicate with Database. A JDBC Data Source with Database connection details should be associated to connection pool. JNDI Name used for creating connection pool should match the value entered for database connection when building application using JDeveloper.

 

1.  Create JDBC Data Source: 

Navigate to Services -> Data Sources

 

Click New button and select Generic Data Source to create a new JDBC Data Source as shown in above screen shot

Enter following details:

Data Source Name:  XEDB

JNDI name to refer Data Source: jdbc/XEDB

Database Type: Oracle

Click Next and proceed further

Select the type Database driver to use to connect to Database and click Next.

Enter Database login and host connection details on next screen

i.      Database Name: <sid or service name of Database>

ii.      Host name: <Database Host Name>

iii.      Port: <Database port number>

iv.      Database user name

v.      Password

vi.      Confirm Password.

Note: Some of these values can be obtained from tnsnames.ora file from Oracle client directory.

Click Next to move on and

Click Test Configuration button to validate the connection details provided.

Connection details will be validated and successful message will be displayed as below.

 

Click Finish button. JDBC Data Source with XEDB will be successfully created.

2.  Create Outbound Connection Pool for DB Adapter:

a.  Click Deployments link in Domain Structure present in left hand side in console window.
b.  In Summary of Deployments window, Select DBAdapter.
c.  DBAdapter settings page will be displayed.

d. Click Configuration tab in DBAdapter setting and select Outbound Connection Pools tab to display list of Outbound connection pools.

e. Click New button to create Outbound Connection Pool.
f. In Create a New Outbound Connection window, select default connection group “javax.resource.cci.ConnectionFactory” and click Next button.

g. Enter JNDI Name, which will be used in JDeveloper to create Database server connection for DB Adapter.

JNDI Name used should match the value entered for database connection when building application using JDeveloper.

Convention followed for DB Adapter JNDI Name is “eis/DB/XEDB”, where, XEDB refers to my XE Database.

Similarly for Apps Adapter, JNDI Name starts with “eis/Apps/” like eis/Apps/AppsDB.

Click Finish.

 

3.  Configure JDBC data source with Outbound Connection pool:

a. Select the newly created Outbound connection pool by selecting JNDI names from the list.

b. In the settings window, click Properties tab.
c. For property name “xADataSourceName”, update the property value with JDBC data source JNDI name which we created in section 1 i.e. “jdbc/XEDB” and click save button.

Note: To change property value, use ENTER key after entering value and click save button.

 

4.   Update Deployment Plan:

a. Go to main Deployments page, update DBAdapter by click Update button.
b. Select Redeploy this application and confirm the deployment plan location.
c. Click Finish button.

5.   Restart the SOA server to use the newly created outbound connection pool JNDI Name “eis/DB/XEDB”.
