Warning! This post is written by using ODI 12.1.2, in version ODI 12.1.3 there are changes in agent setup. A post about ODI 12.1.3 will be written soon.
Hello all,
In this post I am going to tell you how you can set up a standalone agent for ODI 12c. Oracle provided a new tool for configuring our ODI 12c setup elements, such as WLS, Console, Agent, RAC. But to use this configuration manager you will need to create some schemas for OPSS, AUDIT, AUDIT VIEWER and luckily we have RCU for this task, you may do it manual also. But I prefer automation and I will describe in this post how you do it with RCU.
Important! Notice that even if you have a database which can work with ODI 12c, it can be unsuitable with RCU. I faced this problem, I had Oracle 11.2.0.3 for my ODI repository but RCU needed a newer version, so I installed ODI 12c database.
Remember! The paths I will give in this post are absolute paths for my installations, your path may change depending on where you have installed ODI 12c.
Shortly we are going to do
- Create required repository and schemas by using RCU
- Create a domain to run agent by using Configuration Manager
- Define physical agent on ODI Studio
- Run agent
- Test it from ODI Studio
1. Creating necessary schemas
You will find RCU tool in /home/oracle/Oracle/Middleware/Oracle_Home/oracle_common/bin for Linux OS and C:OracleMiddlewareOracle_Homeoracle_commonbin for Windows OS. File name is RCU.cmd or RCU.sh depending on OS. Start the RCU, select “Create Repository” and continue.
Fill all the spaces for the database you want to connect, be sure to enter full service name. In screenshot you will see it is filled as “orcl122” but full service name is “orcl122.localdomain”. I took the screenshot a bit early. Don’t let it trick you.
You will need to select schemas for RCU to create, Oracle Platform Security Services, Audit Services, Audit Services Viewer must be selected. When you check Audit Services, Audit Services Viewer and Audit Services Append will be checked automatically. Also in this step you can choose RCU to create Master and Work Repository for you. Since I have already created my repositories long ago I will skip it.
Set passwords for schemas that are going to be created. I will choose to set same password for every schema.
Set tablespace for schemas. If you leave it default, RCU will name them with a prefix which is set on third step. If tablespaces does not exist RCU will create them for you.
Now RCU will show you a summary of settings, check the list if it seem fine click on “Create”. It will take some time to create schemas, tablespaces, tables then it will show you a report. And you are ready to close RCU and continue with Configuration Manager.
2. Creating Domain for Agent with Configuration Manager
Start Configuration Manager, you can find it in /home/oracle/Oracle/Middleware/Oracle_Home/oracle_common/common/bin on Linux OS and in C:OracleMiddlewareOracle_Homeoracle_commoncommonbin in Windows OS. File name is config.sh or config.cmd depending on OS. Select “Create a new domain” and select where you want to put domain’s files. I will leave it as it is.
Next page is Template Selection page, we will need to check “Oracle Data Integrator – Standalone Collocated Agent” and when you check this option there will be two more options checked automatically.
Next step will want you to create a login for WLS. Password should be at least eight characters, including at least one letter and one number.
Select Domain Mode and JDK, I will leave them default.
Now we will select RCU Data option, since we created necessary schemas with RCU. Enter connection information for the database schema where RCU worked on before. Then click on “Get RCU Configuration” and wait for Configuration Manager to read from database. Then click “Next” when it is available.
Enter all passwords and schemas we have created before. Also you will need to fill database connection information again.
Configuration Manager will check for connections if they are working.
Now we need to select components which we are going to need, In this case we will only select “System Components” and “Deployments and Services” and continue.
Set name for the agent I will use OracleDemoAgent for this demo.
Next select the component from dropdown list, which we have created one step ago. Set listener information you can leave port as 21910 it is default for configuration manager. Fill in supervisor user information. And continue, for this demo we will leave settings default on other steps then click on “Create” on last step.
Creation will take sometime after that click on “Next” and “Finish” and we are almost ready to run the agent.
3. Defining Physical Agent in ODI Studio
Run ODI Studio, and login to repository, where you have Topology rights. We will need this rights to create agents.
Go to Topology tab, in Physical Architecture accordion, right click on “Agents” and click on “New Agent” a new window will appear on right panel.
Name the agent as the same name as we selected in Configuration Manager for the Agent component. When we try to run agent, it will search for its name in Master Repository so names should match exactly. Set the port as you set in Configuration Manager. Save the agent.
4. Start up the agent
Open a terminal/command line window and go to the domain folder that you have created. Under this folder you will find bin folder. For me this folders path is /home/oracle/Oracle/Middleware/Oracle_Home/user_projects/domains/demo_domain/bin in Linux OS or C:OracleMiddlewareOracle_Homeuser_projectsdomainsdemo_domainbin in Windows OS. Run the command agent with NAME parameter as following, or as you can see in screenshot. agent -NAME=OracleDemoAgent
Agent will start to rise up, it will connect to Master Repository, check for its name, read other configurations and start the service and listener. When agent is fully started, command line will seem like screenshot below.
5. Test the agent from ODI Studio
Now we have the agent up and running, also we have a definition for it in our Master Repository and a GUI in ODI Studio. It’s time to test if ODI Studio can connect to agent service. Go to Topology tab and open the agent we have created. There you will see a button written “Test” click on it. If everything is right until here you should see the screen below.
We have completed everything now. Agent is up and ready to run your jobs on databases for you.
