How to process the variable from one instance to another instance? A to identify the unique service number Why do we need to have messages in WSDL, aren't operations and types enough to describe the parameters for a web service? A yes we need the messages in wsdl because in wsdl we have input and output messages and that msg would refer to bpel.
As operations and types are alone not enough. Actually the msgs are linked with XSD elements. So msgs are mandatory in wsdl. Routings are of 2 types? Content based routing Header Based routing Invoke Pick on branch Receive Wait Checkpoint What are the break point activities?

Other services :It depends upon their functionality. Whenever any message or timer expires then bpel server locates and loads the particular bpel process instances and loaded into memory. This process is known as rehydration. A It is exposed to the calling applications or services.
Q What is Business Service? A It connects to the EIS layer. Business services are Oracle Service Bus definitions of the enterprise services that exchange messages during business processes. A No, we can not expose Business Services to external clients or subscribers. We need Proxy Services to expose to external world.
EIS layer can not be connected using that Proxy Service. Q What is the message flow in Proxy Services? A Message flow in OSB is the most important part. It defines the request message flow from Start Node to Route activity and also defines the response message flow from Route to Start Node. Q What are stages? We need to call that Business Service to perform database operations. A Yes we can use XQuery execute-sql function to connect to database. But it is better to use JCA adapters.
Q How we can achieve parallel processing in OSB? So we need to implement Split — Join resources to achieve parallel processing. Q What are the transformation resources available in OSB? Q How to poll file in OSB? It can be implemented using Branch Nodes. Q What is Pipeline Error Handler? Q How can you end a Proxy flow without using if then else logic?
Q How can you jump control from one stage to next stage without using if then else logic? A You have to use Skip action at the end of the stage. In a distributed OSB system, if you have been asked to create 2 separate queues residing on 2 MS, how you will implement this? Ans: using Assing activity in SOA11g 5.
It may be helpful. OSB 11g - Throttling Throttling is termed as " regulate the flow". Oracle Service Bus has throttling feature and by using that feature we can control number of requests sent to target service. But why we need OSB throttling? Every system has its own capacity means it can process only certain number of message at one time, if we try to send messages beyond its capacity then that system's performance can degrade or in worst case it can crash.
So to avoid all this we can use OSB throttling feature to send limited messages to target system. Oracle OSB Interview Questions and Answers:- Configuring Proxy Services and Business Services:- Oracle Service Bus proxy services and business services provide the means for managing services, transforming messages, and routing messages through the enterprise. You can create and configure proxy services and business services using either the run-time environment Oracle Service Bus Console or the development environment What is a Proxy Service?
Oracle Service Bus proxy services are definitions of intermediary Web services that Oracle Service Bus implements and hosts locally. Oracle Service Bus uses proxy services to route messages between business services such as enterprise Web services and databases and service clients such as presentation applications or other business services. A proxy service configuration includes its interface, transport settings, security settings, and a message flow definition.
The message flow definition defines the logic that determines how messages are handled as they flow through the proxy service. Oracle Service Bus business services are definitions of enterprise Web services to which Oracle Service Bus is a client. Those external Web services are implemented in and hosted by external systems, so Oracle Service Bus must know what to invoke, how to invoke it, and what to expect as a result.
Oracle Service Bus business services model those interfaces so that Oracle Service Bus can invoke the external services. A business service configuration includes its interface, transport settings, and security settings. It does not include a message flow definition. What are the different types of Pipelines? Request and Response Pipeline. What is a Pipeline?
Pipelines are one-way processing paths that include no branching. A pipeline is a named sequence of stages containing actions, representing a non-branching oneway processing path. It is used to specify the message flow for service requests and responses. A stage is a user-configured processing step. Messages fed into the pipelines are accompanied by a set of message context variables that contain the message contents.
They can be accessed or modified by actions in the pipeline stages. What is a Pipeline Pair? Pipeline pairs are request and response pipelines. The request pipeline definition specifies the actions that Oracle Service Bus performs on request messages to the proxy service before invoking a business service or another proxy service. The response pipeline definition specifies the processing that Oracle Service Bus performs on responses from the business or proxy service that the proxy service invokes before returning a response to a client.
What is a Message Flow? You configure the logic for the manipulation of messages using proxy service message flow definitions. This logic includes such activities as transformation, publishing, and reporting, which are implemented as individual actions within the stages of a pipeline.
What is a Publish Table? Use a publish table action to publish a message to Zero or more statically specified services. What is a Publish Node? We Use a publish action to identify a statically specified target service for a message and to configure how the message is packaged and sent to that service.
Table summarizes the main elements used to define WSDL services. A message consists of parts, which describe the logical, abstract content of the message. A message consists of parts, each of which describes one logical, abstract unit of the message. A WSDL can define one or more messages, each of which may have one or more parts. The port type provides the public interface for the operations provided by the service. The fragment in Example specifies the binding for the StockQuotePortType port type, which is provided as the value for the type attribute.
In that subelement, the style attribute specifies that the data format is SOAP document style, and the transport attribute specifies that the transport protocol is HTTP.
A port is defined as a binding associated with a network address. These are alternative ports available for this service. Answer: we will use Proxy service to connect to Source system. Question: To connect to target system which service we will use? Answer: we will use Business service to connect to target system.
Question: What is Proxy Service? A proxy service can route messages to multiple business services. Answer: Business services are Oracle Service Bus definitions of the enterprise services that exchange messages during business processes. It is a service in OSB which is used to connect to target system. Question: What is Message Flow?
Answer: A message flow is the implementation of a proxy service. Question:-What is Start node? Answer: Every message flow begins with a start node. All messages enter the message flow through the start node, and all response messages are returned to the client through the start node. There is nothing to configure in a start node. Set its name as name and type as string. BPEL design.
But if your table includes your lookup value multiple times you'll find that VLOOKUP The screenshot below shows this formula in action: Remember that the ROW function returns the row in the worksheet where our value was found.
That was a simple BPM 10g way to convert an introspected database table into a Business Object in mediators or assignment activities two places likely to have mistakes. Architecture SOA through composition orchestration and coordination of Web services.
BPEL provides a relatively easy and straightforward way to compose several language that supports the Web services technology stack including SOAP You can also construct loops declare variables copy and assign values. For an optimalbrowsing experience please click 'Accept'. Sign in to your account or start a free trial. Time for action appending multiple values to a variable Advance your knowledge in tech. Example: I use a simple assign activity to assign 2 elements of input to output.
Doing so makes it easier to access these values in an Embedded Java activity. Tick: Would you like to add resources to this JMS system module?
Search for the project schemas by clicking on magnifier icon and choose the UsersCollection element. When you create variables in your flows Power Automate Desktop converts To create a Text value variable use the Set Variable action and You can create a list through the Create new list action and add an item variable contains a table of values extracted from an Excel worksheet Dates and time.

This action doesn't produce any variables matching type such as Date Time for dates Numeric for numbers and so on. Invokes no stack depth increase Page 2 oracle.
For example if nodatafound set assignees to alternate value force Show MoreShow Less. Return to BPEL Designer mode and click the Process Map button You use the assign activity to concatenate the string Hello a variable or element part as the destination for the data. For more information about the repeatUntil activity, see, Section In BPEL 1. For more information about the replay activity, see Section This activity allows the process to send a message in reply to a message that was received through a receive activity.
The combination of a receive activity and a reply activity forms a request-response operation on the WSDL port type for the process. This activity enables you to rethrow a fault originally captured by the immediately enclosing fault handler. Figure A shows a rethrow activity within a fault handler catch activity.
For more information about rethrowing faults, see Section This activity consists of a collection of nested activities that can have their own local variables, fault handlers, compensation handlers, and so on. Each scope has a primary activity that defines its behavior. The primary activity can be a complex structured activity, with many nested activities within it to arbitrary depth. The scope is shared by all the nested activities. Define appropriate activities inside the scope activity.
Fault handling is associated with a scope activity. The goal is to undo the incomplete and unsuccessful work of a scope activity in which a fault has occurred. You define catch activities in a scope activity to create a set of custom fault-handling activities. Each catch activity is defined to intercept a specific type of fault. Figure A shows the Add Catch icon inside a scope activity. Figure A shows the catch activity area that appears when you click the Add Catch icon. Within the area defined as Drop Activity Here , you drag additional activities to create fault handling logic to catch and manage exceptions.
For example, a client provides a social security number to a Credit Rating service when applying for a loan. This number is used to perform a credit check. If a bad credit history is identified or the social security number is identified as invalid, an assign activity inside the catch activity notifies the client of the loan offer rejection.
The entire loan application process is terminated with a terminate activity. This activity enables you to define a collection of activities to be performed in sequential order.
For example, you may want the following activities performed in a specific order:. A reply message with the final approval status of the request is sent back to the customer in a reply activity. A sequence activity makes the assumption that the request can be processed in a reasonable amount of time, justifying the requirement that the invoker wait for a synchronous response because this service is offered as a request-response operation.
When this assumption cannot be made, it is better to define the customer interaction as a pair of asynchronous message exchanges. When you double-click the Sequence icon, the activity area shown in Figure A appears. Drag and define appropriate activities inside the sequence activity. This activity is used in a master process to notify detail processes to perform processing at runtime and used in detail processes to notify a master process that processing has completed.
For more information about the SMS activity, see Section This activity consists of an ordered list of one or more conditional branches defined in a case branch, followed optionally by an otherwise branch.
The branches are considered in the order in which they appear. The first branch whose condition is true is taken and provides the activity performed for the switch. If no branch with a condition is taken, then the otherwise branch is taken. If the otherwise branch is not explicitly specified, then an otherwise branch with an empty activity is assumed to be available.
The switch activity is complete when the activity of the selected branch completes. A switch activity differs in functionality from a flow activity. For example, a flow activity enables a process to gather two loan offers at the same time, but does not compare their values.
To compare and make decisions on the values of the two offers, a switch activity is used. The first branch is executed if a defined condition inside the case branch is met. If it is not met, the otherwise branch is executed. A terminate activity enables you to end the tasks of an activity for example, the fault handling tasks in a catch branch.
For example, if a client's bad credit history is identified or a social security number is identified as invalid, a loan application process is terminated, and the client's loan application document is never submitted to the service loan providers. Figure A shows several terminate activities in the otherwise branch of a switch activity. For more information about the terminate activity, see Section For more information about the throw activity, see Section This activity enables you to create a transformation that maps source elements to target elements for example, incoming purchase order data into outgoing purchase order acknowledgment data.
This dialog enables you to perform the following tasks:. Click the Edit icon third icon to edit an existing XSL file. This activity enables you to design a BPEL process in which you do not explicitly select a notification channel during design time, but simply indicate that a notification must be sent. The channel to use for sending notifications is resolved at runtime based on preferences defined by the end user in the User Messaging Preferences user interface of the Oracle User Messaging Service.
If the end user does not select a preferred channel or rule, email is used by default for sending notifications to that user. This activity enables you to validate variables in the list. The variables are validated against their XML schema. For more information about the validate activity, see Section 6.
For more information about the voice activity, see Section This activity allows a process to specify a delay for a certain period or until a certain deadline is reached. A typical use of this activity is to invoke an operation at a certain time. This activity enables you to wait for a given time period or until a certain time has passed. Exactly one of the expiration criteria must be specified. For more information about the wait activity, see Section This activity supports repeated performance of a specified iterative activity.
The iterative activity is repeated until the given while condition is no longer true. You can enter expressions in this dialog. For more information about the while activity, see Section For more information about the adapters described in the following sections, see Oracle Fusion Middleware User's Guide for Technology Adapters.
This adapter acts as both a dequeue inbound and enqueue outbound messaging adapter. In the inbound direction, the adapter polls the queues for messages to dequeue from a destination. In the outbound direction, the adapter enqueues messages to the queue for subscribers to dequeue.
Oracle B2B is an e-commerce gateway that enables the secure and reliable exchange of transactions between an organization and its external trading partners. Oracle B2B and Oracle SOA Suite are designed for e-commerce business processes that require process orchestration, error mitigation, and data translation and transformation within an infrastructure that addresses the issues of security, compliance, visibility, and management.
This adapter is used as a reference binding component in a SOA composite application. To access an existing relational schema, you use the Adapter Configuration Wizard to do the following:. This option supports the propagation of both identities and transactions across JVMs and uses the T3 optimized path. Both synchronous and asynchronous invocation patterns are supported.
This adapter acts as both an inbound and outbound adapter. In the inbound direction, the adapter polls for files in a directory to retrieve and process. In the outbound direction, the adapter creates files in a directory. This adapter acts as both a consume inbound and produce outbound messaging adapter. In the inbound direction, the adapter polls consumes messages from a JMS destination. In the outbound direction, the adapter sends produces messages to a JMS destination.
This adapter provides comprehensive, bidirectional, multimodal, synchronous, and asynchronous connectivity to Oracle Applications. The adapter supports all modules of Oracle Applications in Release 12 and Release 11 i , including selecting custom integration interface types based on the version of Oracle E-Business Suite.
The adapter provides real-time and bidirectional connectivity to Oracle Applications through interface tables, views, application programming interfaces APIs , and XML Gateway. To retrieve data from Oracle Applications, the adapter uses views. You can use this adapter to create a client or server socket, and establish a connection. The data that is transported can be text or binary. This adapter enables you to integrate third-party adapters into a SOA composite application.
For more information, see Section 2. The Oracle Service Registry OSR provides a common standard for publishing and discovering information about web services. This section provides an overview of how to publish a business service. For specific instructions, see the documentation at the following URL:. You can also access the documentation by clicking the Registry Documentation icon in the upper right corner of the page. If successful, click Finish. Otherwise, click the Back button and correct your errors.
Drag a Web Service icon into the External References swimlane. Select the published business service, and click OK. Figure A provides details. The composite. The property dynamically resolves the endpoint binding location at runtime. If you want, you can also resolve the SOAP endpoint location by explicitly adding the oracle.
This action dynamically resolves the SOAP endpoint location at runtime for any external reference to a web service.
Highlight the reference binding component in the External References swimlane. In the Property Inspector , expand the Properties section. In the Name list, select oracle. In the Value field, specify the value for oracle. The orauddi protocol dynamically resolves the WSDL location at runtime. Oracle SOA Suite invokes a service for resolving an endpoint.
Examples and descriptions are shown in Table A The endpointURI property is specified within the binding component section of composite. The endpoint location is specified in the concrete WSDL in the binding component section of composite. In the Properties page of the reference binding component, you can change the endpoint reference and service key values created during design time.
Go to the Manage page and check statistics to see the increase in the number of invocations when not cached the first time. Endpoint services that are shut down or retired but not undeployed are still reachable. Therefore, the cache is not refreshed. If you move the business service WSDL from one host to another, ensure that you change the location in the Registry Control. The Registry Control provides an option for changing the endpoint location. This is a two-step process. The following steps provide an overview.
For more specific details, see the Oracle Service Registry documentation:.
