For detailed installation steps of SOA Suite 12c, you can refer to this link. You will use JDeveloper Create a SOA domain using steps given here. Note that sbconsole is accessible even when just AdminServer is running but to test or deploy any Service Bus project you should start corresponding OSB managed server.
In 12c, sbconsole URL will be translated to url as shown above, when its accessed.
Enter Connection Name and select appropriate Connection Type as shown below. Click Next and give valid credentials.
Click Next and give the server details and Weblogic Domain as shown below. Click Next and do Test Connection. Service Bus Project acts as a container for different resources and Service Bus Application is a high-level container for all these Service Bus projects and Global resources. You usually start development activity with creation of new Service Bus Application.
You will see a file with same name as your project called project overview file which opens up Service Bus Overview editor when opened. You can do this by copying WSDLs into project directory directly in file system.
Click Refresh in Project Explorer so that these resources will be shown. Now your Project Explorer should look like below. So you have to create 3 business services using the given 3 WSDLs. Give name as CustomerServiceBS. Retain default values for all parameters in all other tabs Transport Details, Message Handling, Performance and Policies of business service.
Since you already created these resources, you can Refactor them into desired folders. Right click CustomerService. Give folder as WSDLs as shown below. Also Refactor all your business services using steps mentioned below. Typically, if the service provider is external to your organization, then you have to configure business service to use HTTP proxy server.
For this tutorial, you don't need any proxy server configuration. Enter credentials as shown below and click OK to start server. After server starts, verify that test console is opened as shown below. The test console will show you all available operations based on WSDL , Request Document section to enter payload , Transport section to enter transport headers and Attachments section.
Click Execute and observe that you are able to send request and response in test console as shown below. You can use Back button to repeat your test scenarios.
In similar manner, you can verify all other business services. Right click XYZCommon project and choose deploy as shown below. Finish the deployment as shown below. Clicking arrow icon highlighted below will bring up the same test console shown earlier. Select Service Bus Resources option as shown below. Select Configuration Jar as destination.
Click Next and give Jar file name including file system path as shown below and click Finish. Open sbconsle and create new session by clicking Create to import configuration jar.
Click Import icon in Resources tab. Select configuration jar using Choose File button as show below. Click Next. Accept defaults and click Import. Click Close on confirmation screen and verify new project is shown as below in Resources tab. Click Activate and confirm the session so that your changes will be effective. In the same way, to export Service Bus project directly to server choose Server as shown below in Export Service Bus Resources window shown earlier.
Click Next and choose Destination Server as shown below. Accept defaults and click Finish. Creating Pipeline Template In this section, you will learn how to create pipeline templates considering requirements. A pipeline template defines the general shape or pattern of your message flow. Use XYZCustomer project to create all of your resources unless explicitly mentioned. Give name as CustomerPipelineTemplate. Click Finish and verify that new pipeline template has been created and is opened as a separate tab as shown below.
Pipeline templates are the right candidates to keep common logic or enforce pattern of message flow that should be followed across Proxy services. For this tutorial, you may not be creating number of Proxy Services but following are common activities for different operations that your Proxy Service should support. So we will incorporate the following functionality in this Pipeline template.
So let us get started with Pipeline template message flow suiting these requirements. When consumers call proxy service, it has to take different execution paths based on operation being called.
The Service Bus provides Operational Branch node serving this purpose. So drag Operational from Template Placeholders onto Pipeline template where yellow circle is shown. As a best practice, always give meaningful labels for Nodes and other activities wherever applicable.
Now your pipeline template should look like below. Service Bus provides Validate activity to do payload validation against schema. So drag Validate activity into Validation stage from Message Processing. In Properties tab, set Location property value as body and other properties as shown below. Here we dont select any schema or WSDL for validate activity as its just template and we will not have any payload available. There may be additional validations to be performed while designing message flow for concrete pipelines and requires a place holder.
So drag Actions into Validation stage as shown below from Template Placeholders. Delete Stage1 in Response Pipeline by selecting Delete option on right click. Also you may need to create several Stage nodes in your concrete Pipelines message flow. So create place holder for the same in template. Now your Pipeline should look like below.
Routing node always depicts end of message flow and you can't place any other activities after this node. Observe Actions placeholder which allows user to place any type of activity while designing message flow for your concrete pipelines.
Error handling is another aspect of message flow where you should follow similar approach for different Proxy Services that you create.
So you can always create placeholder in your template. You will finish this ErrorHandler stage later in Error Handling section.
With this, you are done with pipeline template and can proceed with creation of other pipelines using this template. Creating Proxy Service In this section, you will learn how to create pipeline using pipeline template and expose it as Proxy Service. First things is, you should come up with a WSDL having Create, Update, Delete and Merge operations as mentioned in business requirements section that can be used for creating Proxy Service.
All the user processes that are connected to the database share an access to it. Shared pool- It captures information to be shared with users. For example: stored procedures, SQL statements etc can be cached for reusability and fast access. Redo Log Buffer- It maintains a log of changes that are made in the database.
The redo log files run in circular motion and get overwritten. So, to maintain the recoverability of the database for longer duration, they are archived into archive logs. Therefore, redo log helps to recover an instance when there is a system failure. This improves the performance and functioning of the database system. Large pool- It is the optional area that offer memory allocations for large processes, like recovery operations and Oracle backup.
Locks- For controlling the simultaneous access to data resources, locks are used. Because these structures are separate, the management of physical storage of data does not affect the access to logical structures. We have tried to cover all important parameters and terms used in Oracle. The Oracle release notes provide information about where to find the compatibility matrix and the system requirements for the server.
