How do I create a fault policy on BPEL?
First Right click on SOA folder -> create from Gallery -> Fault Policy Document. It’ll create fault-policies. xml file under SOA directory. In the above image if you observe, Fault Name is selected as ‘remote Fault’ which means when the external service is not available, then SOA will execute this fault policy.
What is fault handling?
Fault handling allows a BPEL process to handle error messages or other exceptions returned by outside Web services, and to generate error messages in response to business or run time faults.
How do I invoke REST services in BPEL?
Invoking JSON Rest service in BPEL 12c
- Create a REST reference(without choosing the WSDL interface)
- Configure the REST bindings with JSON payload in the Request and Response.
- A native schema is created with a sample JSON ( payload to be sent to the REST reference)
What is remote fault in BPEL?
In SOA BPEL it may include invoke activities which calls the external services. When those external services are not available then you may get remote/ binding faults. If you implement catchall in your BPEL at main scope then when these faults occurred catchall flow will be executed automatically.
What is SOA fault policy?
Fault handling framework is used to handle faults using fault policy and fault binding files. In earlier version of SOA suite which was 11g, we have to create these files manually. There was no provision to create these files from any wizard.
What are the methods to return a fault from a process?
Methods to Return a Fault from a Process
- Use an output. . This is suitable when you foresee that the error might occur and you want to use a data decision step to branch the process based on the normal process flow.
- Throw a fault. .
What is OIC scope?
Scope can catch the error and move ahead to the next logical step in the integration. This does not stop the integration abruptly but rather moves to the next logical step(ex. if there is any Loop, loop will continue to execute).
How do I call a REST API from Oracle SOA?
SOA 11g – Call RESTful service from SOA
- Configure HTTP Binding adapter to call RESTful service.
- Specify RESTful service endpoint and choose request and response schema elements. Use same schema that we used in previous post.
- Now wire your BPEL process with HTTP Binding adapter.
- Deploy your process and test it.
What is REST adapter in SOA?
The REST Adapter is an important new feature of Oracle SOA Suite 12c. This new adapter allows easy calling/exposing of RESTful services (see https://technology.amis.nl/2014/05/14/what-is-rest/ for an introduction to REST) based on a WADL or configured manually.
What are types of the faults in BPEL?
There are two categories of BPEL faults: Business faults. Run-time faults.
Which of the following we can use to design and edit fault policies?
With the Fault Policy Editor you can now Design and Edit Fault Policies.
What are the steps in handling a page fault?
Steps for handling page fault
- The memory address requested is first checked, to make sure it was a valid memory request.
- If the reference was invalid, the process is terminated.
- A free frame is located, possibly from a free-frame list.
- A disk operation is scheduled to bring in the necessary page from disk.
Why do page faults occur?
A page fault occurs when an access to a page that has not been brought into main memory takes place. The operating system verifies the memory access, aborting the program if it is invalid. If it is valid a free frame is located and I/O requested to read the needed page into the free frame.
What is OIC fault handler?
Oracle Integration Cloud Service provides “Global Fault Handler” to catch errors/faults in orchestrated integration and perform actions. In an event of a fault in an integration it goes to “Global Fault Handler” to perform some user define actions like notifying about error by sending email notification etc.
What is OIC hospital error?
The ‘Raise Error’ (Error Hospital) and ‘Create Error’ actions in the error handler implementation will bubble the error up and result in the flow instance being marked as faulted. Such instances can be seen in monitoring console as faulted instances.
What is REST service in SOA?
The REST Web Service approach is an approach for using REST purely as a communication technology to build SOA. In this case, services are defined using SOA style decomposition and REST-based Web Services[9] are leveraged as a transport.
How do I create a rest adapter for SOA 12c?
Steps to create a REST Service in SOA 12c:
- Step 1: Create a new Project in Jdeveloper.
- Step 2: Select SOA Project and Click Ok.
- Step 3: Name the project as per your context and hit finish button.
- Step 4: Right click on Components lane and select the component BPEL Process.
- Step 6: BPEL component gets configured.
Can we use REST in SOA?
REST can be used as both system design approach leveraging ROA (true REST approach) and SOA design implementation leveraging REST technologies (REST Web Services).
How do you reduce page faults?
In general, having a smaller memory footprint, and having things that will often be accessed around the same time be on the same page will decrease the number of page faults.
What is page fault explain?
In computing, a page fault (sometimes called PF or hard fault) is an exception that the memory management unit (MMU) raises when a process accesses a memory page without proper preparations. Accessing the page requires a mapping to be added to the process’s virtual address space.
How do you handle page faults?
Once virtual address caused page fault is known, system checks to see if address is valid and checks if there is no protection access problem. If the virtual address is valid, the system checks to see if a page frame is free. If no frames are free, the page replacement algorithm is run to remove a page.
How do you handle errors in OIC?
To achieve this we have to configure “Default Fault Handler” (at Scope Level). Scope can catch the error and move ahead to the next logical step in the integration. This does not stop the integration abruptly but rather moves to the next logical step(ex. if there is any Loop, loop will continue to execute).
What is global variable in OIC?
Global Variables and Data Stitch in OIC
Global variables and Data Stitch activity are two recently added features in OIC. A global variable is accessible to the entire integration instance including all scopes. Its type can be simple such as a string or an object such as a custom defined complex schema type.
How does OIC process large files?
Large File Handling
If you need to read larger files, there is an option to “Download file”. This option handles files up to the size of 1 GB and allows files to be directly downloaded into OIC local file system without reading into memory. The Downloaded files are accessed with the help of Stage Activity.
What is difference between REST and SOAP?
REST is a set of guidelines that offers flexible implementation, whereas SOAP is a protocol with specific requirements like XML messaging. REST APIs are lightweight, making them ideal for newer contexts like the Internet of Things (IoT), mobile application development, and serverless computing.
