There
are some times Where we need to move applications from One Domain to
another. The most important aspect during this phase is the creation
of Data Sources in the New Domain.
This
article tell you how to Copy a Data Source from one Domain to
another.
1.Copy
the Data Souce xml files from the location ,
WL_HOME\user_projects\domains\<YOUR_DOMAIN_NAME>\config\jdbc
folder
to
the same location of another domain (or in another machine )
2.Make
entry in the config.xml file.
Once
the copying of the data Souce .xml files is done , we need to make
entry for the jdbc data Souces in the config.xml file which is
located at BEA_HOME\user_projects\domains\YOUR_DOMAIN_NAME\config
folder.
For
example ,if we are copying cbs_Pool to another Domain ,we can locate
admin-server-name node in config.xml file and add below entries for
each Datasource.
<jdbc-system-resource>
<name>cbs_Pool</name>
<target>ABCE-A,ABCE
-B,ABCE -C</target>
<descriptor-file-name>jdbc/cbs_Pool-9207-jdbc.xml</descriptor-file-name>
<jdbc-system-resource>
Just
repeat the same steps for every Data Source we are copying.
3.Now
the last and final Important Part is to set passwords for the Data
Sources copied. Every Data Sauce in a domain is encrypted using the
SerializedSystemIni.dat file available in
BEA_HOME\user_projects\domains\YOUR_DOMAIN_NAME\security folder.
First
Decrypt the passwords for the Data Sources using the Old Domain
SerializedSystemIni.dat File. Here is a link on how to do this.
Once
the Passwords are decrypted , We now need to encrypt again using the
new Domain SerializedSystemIni.dat file.
We
can use the available web logic command like
java
weblogic.security.Encrypt <Password To Encrypt>
to
encrypt the passwords.
Once
the Passwords are encrypted , we can modify the password element in
the dataSouce.xml file that we copied.
4.Restart
the admin Server and Cluster for the changes to take effect.

to Come , Happy learning :-)
