The Specifics of ADF 12c Production Domain Deployment

Next to the recent release of Oracle JDeveloper 12c and ADF 12c, many  developers and ISVs would want to migrate to the new version. Therefore let’s take a look on the deployment of ADF 12c in production domain.

In this post I would like to cover simple use case of deployment sample ADF 12c production domain. In order to do this it is necessary to have the following components: Application Development Runtime (12.1.2), Oracle Database 11g Express Edition (NOT CERTIFIED, but suitable for our sample, for enterprise production or development environments it will be needed Oracle DB SE OneSE or EE) and JDK 7.

All links for products distributives you could find bellow:

In our example we will demonstrate deployment process in MS Windows OS environment.

There are also some useful links bellow, which could be interesting:

I would like to pay attention to the following important facts: 

  1. The available Oracle WebLogic (12.1.2) installer is generic and can be used on any supported platform. Platform-specific WebLogic Server installers are no longer provided. Also installation program no longer includes a JDK.
  2. ADR already contains WebLogic 12с components. So there are two ways of infrastructure deployment:
                              2.1. The first approach involves the use of Oracle WebLogic 12c installers, and after this it is necessary to install ADR.
                              2.2. The second approach use only ADR installer, which installs Oracle WebLogic and ADF runtime components (except JDK).

The following self-extracting installer JARs are available:

  • wls_121200.jar - Installs WebLogic Server and Coherence
  • fmw_infra_121200.jar - Installs WebLogic Server, Coherence, and infrastructure components for Fusion Middleware product platforms.

In our case we will go through shortest way using only ADR installer.

Let’s consider the whole process step by step:

Stage 1: JDK installation.

In our case we use Java SE version 7u25. But it is possible to use also Oracle JRockit JVM.

Stage 2: Oracle Database XE installation.

RDBMS installation is necessary stage, as in addition to application specific data, you should install the metadata schemas on a database which certified for this release of Oracle Fusion Middleware.

NOTE: It is important to know that Oracle Database XE 11g is NOT certified for FMW 12c infrastructure. In this case it will be used for sample purposes. For FMW 12c certified the following versions of Oracle Database: 12.1.0.1+; 11.1.0.7+; 11.2.0.3+. Please, be familiar with Oracle Fusion Middleware 12c (12.1.2.0.0) Certification Matrix.

Stage 3:  Fusion Middleware components installation.

On the command prompt use the following command:

<JDK_path>\bin\java -jar fmw_infra_121200.jar  

Example:

C:\Java\jdk1.7.0_25\bin\java -jar fmw_infra_121200.jar

NOTE: For Mac OS X environment use the following command:

/usr/libexec/java_home --version 1.7.0 --exec java -jar ./fmw_infra_121200.jar

Let’s look at the key aspects of installation process:

1) On  the 2nd step of installation wizard you should specify Oracle Home directory:

2) On 4th step of installation wizard be aware, that all prerequisite checks have been completed successfully. 

3) Finish the installation process.


Stage 4: DB schemas creation by RCU utility.

You should start RCU with the following command:

<MW_HOME_path>\oracle_common\bin\rcu 

Example:

C:\Oracle\Middleware\FMW12c\oracle_common\bin\rcu 

NOTE: For Mac OS X environment before running RCU use the following commands:

bin $ export DISPLAY=:0
bin $ export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_21.jdk/Contents/Home
bin $ ./rcu

You could get more information about RCU utility in the «Creating Schemas with the Repository Creation Utility» guide:

During launching RCU utility you might get an error that OS cannot found JRE location directory. You could fix this issue by the following way:

  • Open rcu.bat batch file in a text editor.
  • Find lines where parameter JRE_DIR was defined, and edit it, adding path to JRE location:

  • Save the file and launch it again.

Let’s look at the key points of this stage:

1) On the 2nd step of configuration wizard you should specify Database Connection Details:

After this, click Next button and the utility will make all the necessary checks and report about database incompatibility. Click Ignore here to continue process.

2) On the 3rd step of configuration wizard, you should specify schemas prefix and check AS Common Schemas in the components tree:

3) On the 4th step of configuration wizard, you should specify passwords for schemas:

4) On the 5th step of configuration wizard, RCU makes tablespaces configurations. You could change default values here:

5) After the completion of the 6th step of configuration wizard, click the Close button.

Stage 5: Domain deployment and configuration.

In order to configure domain we will use Configuration Wizard utility:

In order to start wizard you should execute the following command:

<MW_HOME_path>\oracle_common\common\bin\config.cmd

Example:

C:\Oracle\Middleware\WebLogic1212\oracle_common\common\bin\config.cmd

Let’s look at the key points of this stage:

1) On the 2nd step of configuration wizard, check the following options in Available Templates list: 

  • Oracle Enterprise Manager - 12.1.2.0 [em]
  • Oracle JRF - 12.1.2.0 [oracle_common]
  • Weblogic Coherence Cluster Extension - 12.1.2.0 [wlserver]

2) On the 5th step of configuration wizard, specify Production Mode and leave and JDK path the same:

3) On the 6th step of configuration wizard, specify DB connection parameters, and RCU service table (STB) schema credentials. Click Get RCU Configuration and ensure that Connection Result Log is OK. Click Next.

4) On the 9th step of configuration wizard, check Administration ServerManaged servers, clusters and coherence options. We will configure its later. Click Next.

5) On the 11th step of configuration wizard, click Add button in order to add managed server and specify it name as ADFManagedServer. Leave other parameters with its default values and click Next.

6) On the 14th step of configuration wizard, click Add button to add machine as ADFMachine and then click Next.

7) On the 15th step of configuration wizard, target AdminServer and ADFManagedServer to ADFMachine and click Next.

8) On the 16th step of configuration wizard, click Create button and wait until wizard will create and configure domain. Click Finish after this.

9) Domain creation now has been completed.

Stage 6: Additional configuration of the domain and other components.

Execute command below and run AdminServer:

<MW_HOME_path>\user_projects\domains\<domain_name>\bin\startWebLogic.cmd

Example:

C:\Oracle\Middleware\WebLogic1212\user_projects\domains\ADFDomain\bin\startWebLogic.cmd

During the domain configuration process, we specified Production mode, so in our case you need to input weblogic account credentials to run AdminServer. After this wait until AdminServer goes to state RUNNING.

Navigate to WebLogic Administartion Console, on URL:

http://<host_name>:7001/console

Log in using weblogic account.

In our configuration we will not use SSL encryption in the Node Manager configuration. So in order to use Plain type let’s make the following steps:

1) Go in the Domain Structure tree to Machines node. Click on our ADFMachine and go to the Node Manager tab. Click Lock & Edit to edit current configuration and select Plain value of Type parameter. Click Save и Activate Changes in order to save current configuration.

2) Open nodemanager.properties file located in the following path in the text editor:

<MW_HOME_path>\user_projects\domains\<domain_name>\nodemanager\nodemanager.properties


Example:


C:\Oracle\Middleware\WebLogic1212\user_projects\domains\ADFDomain\nodemanager\nodemanager.properties

Edit SecureListener parameter, and specify it value as false.

SecureListener=false

3) Run Node Manager service, using the following command:

<MW_HOME_path>\user_projects\domains\<domain_name>\bin\startNodeManager.cmd

Example:

C:\Oracle\Middleware\WebLogic1212\user_projects\domains\ADFDomain\bin\startNodeManager.cmd

4) Restart AdminServer and ensure that the Node Manager is available and has Reachable status. You could check it in Monitoring tab and Node Manager Status tab inside it.

Stage 7: Targeting JRF libraries on managed servers.

For regular ADF Application with working Enterprise Manager Fusion Middleware Control, it is necessary, to target JRF (Java Required Files) libraries on managed servers.

1) Navigate to Enterprise Manager Console, using URL:

http://<host_name>:7001/em

Log in, using weblogic account.

2) Find out single managed server (in our case) ADFManagedServer in components tree. Click Apply JRF Templates button. Wait until the operation is complete. Targeting libraries is complete now.

3) Now it is necessary to run our managed server. Select Control -> Start Up in the context menu of managed server. Wait until the process is complete.

4) Ensure that AdminServer and all managed servers (in our case it is one server) are running (has RUNNING stage). You could do this, for example, in the WebLogic Administration Console.

Stage 8: Applications deployment and domain testing.

So all necessary procedures are complete and our sample domain is ready for ADF applications deployment. You could simply deploy your applications using WebLogic Administration Console or Enterprise Manager Fusion Middleware Console and you are ready!

Thanks for the detailed post Emin. Here's some supplemental instructions for running this on OSX that might assist other readers:

Stage 3: Running the fmw_infra_121200.jar in a terminal window

/usr/libexec/java_home --version 1.7.0 --exec java -jar ./fmw_infra_121200.jar

Stage 4: Before running the rcu program

bin $ export DISPLAY=:0
bin $ export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_21.jdk/Contents/Home
bin $ ./rcu
