Convert WebLogic 11g domain into the 12cR2 partition using DPCT (Domain to Partition Conversion Tool)
The Domain to Partition Conversion Tool (DPCT) provides a utility that inspects a specified source domain and produces an archive containing the resources, deployed applications and other settings. This can then be used with the Import Partition operation provided in WebLogic Server 12.2.1 to create a new partition that represents the original source domain. An external overrides file is generated (in JSON format) that can be modified to adjust the targets and names used for the relevant artifacts when they are created in the partition. DPCT supports WebLogic Server 10.3.6, 12.1.1, 12.1.2 and 12.1.3 source domains and makes the conversion to WebLogic Server 12.2.1 partitions a straightforward process.
This part of the tutorial shows how to convert existing Weblogic Server 11g domain into the importable format of WebLogic Server 12cR2 Domain Partition and import that pertition into WebLogic Server 12cR2 domain
Inside VirtualBox VM we have already created Domain1036 in /u01/wins/wls1036/user_projects/domains/Domain1036. This domain contains Admin Server only, we created PetstoreDB as Datasource and Deployed JSF-2.0.war as shared library and deployed petstore.12.war as an application to the Admin Server. This is the source domain, which we are going to convert to the image of the WebLogic Domain Partition through DPCT tool. This process will create a Domain1036.zip and Domain1036-attributes.json file.
We have also created Domain1221 in /u01/wins/wls1221/user_projects/domains/Domain1221. This is empty domain, which contains Admin Server only. This will be our target domain, where we will import the previous domain Domain1036 as partition.
- Configured WebLogic Server 11g domain with sample application
- Configured WebLogic Server 12cR2 domain
- Oracle Database to store demo application's data
Open a terminal window and move to GIT_REPO_LOCAL_CLONE/dpct folder.
$ [oracle@localhost Desktop]$ cd /u01/content/cloud-native-devops-workshop/dpct
Run prepared script that prepares the environment. First starts the container and (PDBORCL) pluggable database. Creates the petstore user in pdborcl database, and populates the database with sample data. Sets the JAVA_HOME to /usr/java/jdk1.7.0_79/ and MW_HOME to /u01/wins/wls1036/ then it starts the Admin Server in Domain1036. Finally sets the JAVA_HOME to /usr/java/latest/ (JDK 8) and MW_HOME to /u01/wins/wls1221/ then it starts the Admin Server in Domain1221.
$ [oracle@localhost dpct]$ ./prepareLocalEnv.sh
Oracle database (sid: orcl) is running.
Open pluggable database: PDBORCL.
PDBORCL is already opened

Go to browser and access the application URL on http://localhost:6001/petstore/faces/catalog.jsp . You can use the Bookmark.
We are using PetStore application which was created by Sun engineers in 2009(!) to demonstrate JEE5 and other features. You can click on different Animal name like Cats, Dogs and Birds. You can also click on Seller and Search for verification of application Execution. Due to external API changes some of the functions do not work of the demo application.
We have put the Domain to Partition conversion tool in /u01/dpct folder.
Go back to terminal window and verify if JAVA_HOME variable is properly set.
$ [oracle@localhost Lab8]$ $JAVA_HOME/bin/java -version
java version "1.8.0_60"
Java(TM) SE Runtime Environment (build 1.8.0_60-b27)
Java HotSpot(TM) 64-Bit Server VM (build 25.60-b23, mixed mode)
[oracle@localhost Lab8]$
The displayed value should be java version "1.8.0_60", which is required for DPCT tool to run.
Move to DPCT folder location and execute DPCT tool
$ [oracle@localhost Lab8]$ cd /u01/dpct
$ [oracle@localhost dpct]$ ./exportDomainForPartition.sh /u01/wins/wls1036/ /u01/wins/wls1036/user_projects/domains/Domain1036/
This command creates the Domain1036.zip and Domain1036-attributes.json file in /u01/dpct/outDir/folder

Go to the browser and type the URL for Admin Console of Domain1221 domain http://localhost:9001/console . Or click on the console bookmark.
Enter weblogic/welcome1 as username and password then click Login.
In Domain Structure click Domain Partitions.
Click Import, specify Microcontainer1 as Domain Partition name and /u01/dpct/outDir/Domain1036.zip as Path then click on OK.
Click Environment -> Virtual Targets, and then click Microcontainer1-AdminServer-virtualTarget.
Modify the URI Prefix to "/" and set Port Offset to 100 and then click Save.
Select Deployments, as jsf-2.0.war is implementation of JSF 2.0 that is part of JavaEE 6 it is already bundled with WebLogic Server 12.2.1 installation, so we don’t need it as part of deployment that was needed in pre JavaEE 6 container (11g). Check the box for jsf(2.0,1.0.0.0_2-0-2) and then click Delete.
Select Domain Partitions and then click Control tab, check the box for Microcontainer1 and click on Start to start the partition.
Wait for 5-6 seconds, and then click Configuration tab of Domain Partitions. Once this partition is in RUNNING State, and then only goes to next step.
Access the Petstore demo application on http://localhost:9101/petstore/faces/catalog.jsp or using the bookmark.
