WLST script to add DataSource and DBAdapter EIS Connection Factory

0 0

Creating a EIS ConnectionFactory in your Database Adapter can be done with the WebLogic Administration Console, but of course this is also “scriptable”. What I needed was a script that created a Data Source with EIS Connection factory bound to the specific datasource.

First I created a properties file, let’s call it DsCf.properties. Everything between <> should be replaced with your own values:

# Propertie file for creating datasource and EIS DB Adapter
# Created by Michel Schildmeijer
# Domain settings
domainname="<your WLS DOMAIN>"
adminurl=<WLS HOST:Admin Port>
adminusername=weblogic
adminpassword=<passwd weblogic>
#datasource settings
datasourcename=<Name DataSource>
datasourcedatabasename=<database>
datasourcetarget=<targeted manaegd server>
datasourcefilename= datasourcename + '.xml'
datasourcejndiname= 'jdbc/' + datasourcename
datasourcedriverclass=oracle.jdbc.OracleDriver
datasourceurl=jdbc:oracle:thin:@<db host>:1521:<db sid>
datasourceusername=<db user>
datasourcepassword=<db user password
datasourcetestquery=SQL SELECT * FROM DUAL
#EIS Connection Factory settings
connfactname=eis/DB/<Connection factory Name>

Second, I created a WLST script to execute these properties and added the DataSource and ConnectionFactory. See the script below.

When running on a UNIX or linux system, navigate to the WLS DOMAIN DIR /bin( Specified during domaincreation) like /app/oracle/middleware/user_projects/domains/<Your domain>/bin and run

./setDomainEnv.sh

After this you are able to deploy the DataSource en ConnectionFactory:

java weblogic.WLST loadProperties DsCf.properties

After finished you can check in the WebLogic Admin Console to see:

• If datasource is created
• If in your outbound connections of the database adapter the EIS connection factory with binding to the DataSource has been created.
