Interview Questions.

Question 1. What Is Bpel?

Answer :

Within the agency, BPEL is used to standardize company utility integration in addition to to extend the integration to previously isolated systems. Between organizations, BPEL permits less difficult and greater effective integration with commercial enterprise companions. BPEL stimulates companies to in addition define their enterprise procedures, which in flip results in business procedure optimization, reengineering, and the selection of the maximum appropriate processes, therefore similarly optimizing the corporation.

Definitions of business processes described in BPEL do not affect current structures, thereby stimulating upgrades. BPEL is the important thing era in environments in which functionalities are already or can be exposed thru Web services. With will increase within the use of Web offerings, the importance of BPEL will boom as well.

BPEL represents a convergence of  early workflow languages; Web Services Flow Language (WSFL) and XLANG. WSFL turned into designed by means of IBM and is primarily based on the concept of directed graphs. XLANG, a block-structured language, turned into designed by means of Microsoft. BPEL combines each processes and provides a wealthy vocabulary for description of business methods.

Question 2. What Is Oracle Jdeveloper?

Answer :

Oracle BPEL Process Manager affords assist for the use of Oracle JDeveloper to graphically design BPEL tactics. 

Oracle JDeveloper is an incorporated improvement surroundings (IDE) for constructing packages and Web offerings the usage of Java, XML, and SQL standards. Oracle JDeveloper helps the whole improvement life cycle with integrated functions for designing, coding, debugging, trying out, profiling, tuning, and deploying programs. A visual and declarative development approach and the Oracle Application Development Framework (ADF) paintings collectively to simplify application development and reduce coding duties.

Oracle JDeveloper uses BPEL as its native layout. This means that procedures constructed with Oracle JDeveloper are 100% transportable. Oracle JDeveloper additionally enables you to view and modify the BPEL source with out reducing the usefulness of the device.

You design BPEL approaches by means of dragging and dropping elements (known as sports) into the method and enhancing their property pages. This gets rid of the need to write down BPEL code. You integrate BPEL tactics with external services (referred to as associate hyperlinks). You also integrate adapters and services which includes workflows, transformations, notifications, sensors, worklist mission management, and enterprise policies with the technique. Oracle JDeveloper can deploy the evolved techniques directly to Oracle BPEL Server. This facilitates the development and upkeep of BPEL processes.

Oracle BPEL Process Manager affords guide for the subsequent services and adapters in Oracle JDeveloper:

Transformations, workflows, worklists, notifications, sensors, and business rules
Technology adapters (report, FTP, database, AQ, JMS, MQ, and Oracle Applications)

Question 3. What Are Two Ways Of Combining Web Services?

Answer :

Web services can be blended in two methods:

Orchestration
Choreography
Question four. Explain Orchestration And Choreography?

Answer :

In orchestration, that's typically used in private commercial enterprise procedures, a important process (which may be another Web service) takes control of the involved Web services and coordinates the execution of different operations on the Web services worried inside the operation. The concerned Web services do no longer "recognise" (and do no longer want to know) that they're involved in a composition process and that they're taking element in a better-level commercial enterprise system. Only the relevant coordinator of the orchestration is aware of this goal, so the orchestration is centralized with express definitions of operations and the order of invocation of Web services.

Choreography, in evaluation, does no longer depend upon a central coordinator. Rather, each Web provider concerned within the choreography is aware of precisely when to execute its operations and with whom to interact. Choreography is a collaborative attempt focusing on the change of messages in public business techniques. All participants in the choreography need to be privy to the business procedure, operations to execute, messages to change, and the timing of message exchanges.

Question 5. What Are Two Different Ways Of Describing Business Processes That Are Supported By Bpel?

Answer :

BPEL supports two specific approaches of describing business strategies that support orchestration and choreography:

 Executable tactics allow you to specify the exact details of enterprise approaches. They follow the orchestration paradigm and may be accomplished by using an orchestration engine.
Abstract commercial enterprise protocols permit specification of the public message trade among parties most effective. They do now not encompass the internal information of procedure flows and aren't executable. They observe the choreography paradigm.

Question 6. List Of All Primitive Activities Supported By Bpel Business Process?

Answer :

Primitive sports constitute basic constructs and are used for common responsibilities, which includes the following:

Invoking other Web services.
Waiting for the purchaser to invoke the business process by using sending a message.
Generating a reaction for synchronous operations.
Manipulating records variables.
Indicating faults and exceptions.
Waiting for some time.
Terminating the entire process.
Question 7. What Is The Use Of Bpel Business Process?

Answer :

In a regular scenario, the BPEL business manner gets a request. To satisfy it, the technique invokes the involved Web services after which responds to the original caller. Because the BPEL manner communicates with different Web offerings, it is based heavily on the WSDL description of the Web offerings invoked by means of the composite Web provider.

Java Interview Questions
Question eight. What Are Two Configuration Settings For Auditing?

Answer :

auditLevel:  

off - absolutely no logging achieved in any way; may bring about a slight overall performance raise for processing instances.
Minimum - all occasions are logged; but, no audit details are logged.
Production - all occasions are logged. The audit details for assign activities aren't logged; the information for all different nodes are logged.
Improvement - all activities are logged; all audit details for all sports are logged.
AuditDetailThreshold: 

The maximum size (in bytes) an audit path information string may be earlier than it's miles saved one after the other from the audit path. If a information string is bigger than the threshold it will now not be right away loaded when the audit trail is initially retrieved; a link may be displayed with the scale of the info string. Typically, the information string will contain the contents of a BPEL variable. In instances wherein the variable could be very huge performance can be severely impacted through logging it to the audit path. The default fee is 50 kilobytes.

Question nine. What Are Two Modes Of Invocation That Are Supported By Bpel Console?

Answer :

BPEL Console supports  modes of invocation: an HTML Form view and an XML Source mode.

The XML Source mode, shown underneath, allows you to enter XML source records immediately into a text form and that supply is passed, as is, to provoke the BPEL method. To simplify using this mode, you may configure default XML information in the deployment descriptor of the method, so one can be pre-loaded into the XML statistics area .

Alternatively, the HTML Form view in the BPEL Console's Initiate tab will mechanically generate an HTML input shape (whilst feasible), which can be used to provide the input values to initiate a BPEL method for trying out functions.

Oracle Exadata Database Interview Questions
Question 10. What Are Alerts For Stuck Bpel Messages?

Answer :

An alert is displayed when there are stuck messages for asynchronous BPEL tactics. A worldwide time threshold is used perceive stuck messages.

Alerts are displayed at more than one stages:

soa-infra
Composite
Flow Trace (PS4)
Question eleven. Explain Bpelx:insertbefore Extension In An Assign Activity?

Answer :

The from-spec query within bpelx:insertBefore yields zero or greater nodes. The node list is appended as child nodes to the goal node certain by the to-spec query.

The to-spec question of the insertBefore operation points to one or more single L-Value nodes. If multiple node is lower back, the primary node is used because the reference node. The reference node ought to be an detail node. The parent of the reference node must additionally be an detail node. Otherwise, a bpel:selectionFailure fault is generated. The node list generated with the aid of the from-spec query selection is inserted before the reference node. The to-spec query can't talk to a associate link.

The following example indicates the syntax before the execution of . The price of addrVar is:

CA
94065
After the execution of the following syntax within the BPEL technique report:
Redwood Shore> 
The value of addrVar now becomes:
Redwood Shore
CA
94065

Question 12. What Are Two Types Of Events Supported By Bpel?

Answer :

Although fault handlers and scopes improve the robustness of BPEL tactics drastically, you may additionally manage events.

BPEL supports two types of events:

Message events are precipitated by means of incoming messages thru operation invocation on port types.
Alarm occasions are time-related and are brought about either after a positive length or at a particular time.
Oracle SOA Interview Questions
Question thirteen. How Many Tables Are Used For Mediator Instance Tracking?

Answer :

There are in total five tables that are utilized by mediator example monitoring:

Mediator_instance - One row for each mediator message waft.
Mediator_case_instance - One row for each mediator case (~ routing rule).
If a mediator component has  routing rules then this must have 2 records for that mediator instance.
Mediator_case_detail - Captures mediator audit trail for every mediator routing rule. Number of records may vary based on the character of mediator element.
Eg: if mediator factor is having a async req-resp routing rule then this will comprise 2 rows for the corresponding mediator routing rule.
Mediator_document - Stores the payload for routing guidelines that are configured as deferred (~ parallel in jdev). So if all of the routing rules are "sequential" then this can not incorporate any records.
Mediator_audit_document - Stores the payload for audit path and most effective when "instanceTrackingLevel" for mediator is "Complete".
Question 14. What Are Various Sources Of Faults In Bpel?

Answer :

Business procedures specified in BPEL will engage with companion methods thru operation invocations on Web services. The communique among Web offerings is typically over internet connections that aren't surprisingly dependable. Web services can also boost faults because of logical and execution mistakes. Therefore, BPEL commercial enterprise tactics want to address faults appropriately and might additionally need to signal faults themselves.

Faults in BPEL can be from various resources:

A BPEL procedure can explicitly signal (throw) a fault.
A fault can arise while the BPEL procedure invokes a Web service operation. The operation would possibly return a WSDL fault message, which leads to a BPEL fault.
A fault may be thrown automatically through the BPEL runtime surroundings, either due to a positive situation inside the BPEL manner itself (inclusive of a join failure), attributable to mistakes conditions inside the runtime environment, or related to network conversation or different reasons. For such situations, BPEL defines several general faults.
Question 15. How Can A Business Process Signal A Fault Explicitly?

Answer :

A business technique sometimes desires to signal a fault explicitly. Therefore, BPEL affords the hobby, which has the following syntax:

BPEL does not require definition of fault names prior to their use in the interest. This flexible method can be errors-susceptible, because there is no bring together-time checking of fault names. In the case of typos, misspelled faults will now not be treated with the aid of the specified fault handler.

Faults can also have an related variable that contains fault facts. If any such variable is needed, you have to specify it while throwing a fault, through the usage of the optionally available faultVariable

Oracle AOL (Application Object Library) Interview Questions
Question sixteen. How Can We Handle Faults In Bpel?

Answer :

When a fault occurs inside a enterprise system, the technique may not whole efficiently. (But it could complete correctly if the fault is handled within a scope, which permits you to divide a complex system into several components; more on scopes later.) The business procedure can cope with the fault through one or extra fault handlers. Within a fault handler, the business process defines custom sports that have to get over the fault and in all likelihood opposite the partial (unsuccessful) work of the hobby wherein the fault has took place.

The fault handlers are detailed before the primary activity of the BPEL procedure, after associate hyperlinks and variables.

The ordinary structure is shown in the following code excerpt:

Within the fault handlers, you specify numerous activities wherein you imply which fault you need to trap and deal with. Within a fault handler, you have to specify as a minimum one or . The activity may be specified most effective once within a fault handler.

Usually you specify several activities in which you will cope with unique faults and use to deal with all different faults. To specify which fault you would like to handle, you should specify at least one of the following:

faultName, which specifies the call of the fault to handle
faultVariable, which specifies the variable kind used for fault data
The flexibility of sports is high, and all of the following variations are permissible:

Fault handlers in BPEL are just like attempt/catch clauses in present day programming languages which include Java.

Question 17. What Is Scopes In Bpel? How Can It Be Useful In Handling Faults?

Answer :

Scopes are hierarchically prepared elements into which a complex commercial enterprise manner may be divided. They provide behavioral contexts for sports. In other phrases, scopes enable you to define specific fault handlers for specific sports (or units of activities collected underneath a common established interest including or ). In addition to defining fault handlers, you may declare variables which are seen best inside a scope. Scopes additionally allow you to define neighborhood correlation units, compensation handlers, and event handlers.

BPEL Interview Questions
Question 18. What Is Inline Fault Handling?

Answer :

In BPEL methods, invocation of operations on Web offerings can be mainly errors-inclined. There are severa situations—together with damaged connections, unavailability of Web services, or changes within the Web services WSDL—that could prevent a BPEL technique from successfully invoking a partner Web provider operation.

Such faults may be handled within the section of the corresponding scope.

Oracle SOA fit 11g Interview Questions
Question 19. Explain The Use Of Message Event And Alarm Events?

Answer :

Managing message events is particularly vital whilst the commercial enterprise technique is watching for callbacks from accomplice Web services. Interest, helps you to look forward to handiest a unmarried (precisely exact) message on a port type. Often, however, it's far extra useful to look forward to multiple message, of which handiest one will occur.

Alarm activities are useful whilst you need the technique to look ahead to a callback for a positive time period, including 15 minutes. If no callback is obtained, the method waft maintains as designed. This approach is specially beneficial in loosely coupled service-oriented architectures, where you cannot depend upon Web offerings being available all the time. This manner, the method flow can proceed despite the fact that one of the bookstores does not go back a proposal.

Question 20. Explain Pick Activity Of Bpel?

Answer :

BPEL gives the interest, thru which you could specify that the commercial enterprise manner should wait for the occurrence of one occasion in a hard and fast of occasions. Events may be message activities handled with the activity or alarm events dealt with with the pastime. For each event, you specify an hobby or a hard and fast of sports that need to be carried out.

Middleware Interview Questions
Question 21. How Can We Use Pick As Initial Activity?

Answer :

You can use the interest rather than the initial pastime. You can specify numerous operations, and receiving this sort of messages will bring about the creation of a enterprise manner example. Then you have to use a special form of the hobby. You specify the createInstance characteristic for the pastime, however you can specify best events; activities are not authorised in this particular shape.

To apprehend using this special shape of the interest, keep in mind the bookstore Web provider, carried out as a simple BPEL manner.

Question 22. How Xml Data Works In Bpel?

Answer :

In a BPEL process, each piece of facts is in XML paperwork. This consists of the messages exceeded to and from the BPEL technique, the messages exchanged with outside services, and nearby variables utilized by the technique. You define the types for those messages and variables with the XML schema, commonly inside the WSDL report for the float, the WSDL documents for the services it invokes, or the XSD document referenced by means of those WSDL documents. Therefore, all variables in BPEL are XML information, and any BPEL procedure uses a lot of its code to manipulate these XML variables. This commonly consists of performing statistics transformation among representations required for specific offerings, and neighborhood manipulation of facts (as an instance, to mix the outcomes from several service invocations).

Question 23. What Is Use Of Assign Activity In Bpel?

Answer :

You use the assign interest to copy facts from one XML variable to any other, or to calculate the cost of an expression and keep it in a variable. A replica element in the interest specifies the supply and target of the project (what to replicate from and to), which ought to be of like minded sorts. 

The formal syntax as shown in the Business Process Execution Language for Web Services Specification is as follows:

popular-elements 
+
from-spec
to-spec

This syntax is defined in detail in that specification. The from-spec and to-spec normally specify a variable or variable component, as in:

Example of assigning a numeric cost to a variable in XPath expressions.

You can assign numeric values in XPath expressions. The following example indicates the way to assign an XPath expression with the integer value a hundred.

Oracle Fusion Interview Questions
Question 24. How Can You Assign Boolean Values To A Field In Xpath Expression ?

Answer :

In this case of assigning Boolean values, the XPath expression inside the from clause is a name to XPath's Boolean characteristic actual, and the required permitted area is set to genuine. The feature false is also to be had.

The XPath specification recommends which you use the "authentic()" and "false()" capabilities as a way for returning Boolean consistent values.

If you instead use "boolean(actual)" or "boolean(false)", the true or fake within the Boolean characteristic is interpreted as a relative detail step, and no longer as any actual or false steady. This method it attempts to choose a toddler node named true under the current XPath context node. In maximum cases, the true node does no longer exist. Therefore, an empty end result node set is again and the boolean() feature in XPath 1.Zero converts an empty node set into a fake result. This end result may be probably perplexing.

Java Interview Questions
Question 25. How Can You Assign The Current Value Of A Date Or Time Field By Using The Oracle Bpel Xpath Function Getcurrentdate, Getcurrenttime, Or Getcurrentdatetime ?

Answer :

You can assign the modern-day fee of a date or time field by the usage of the Oracle BPEL XPath characteristic getCurrentDate, getCurrentTime, or getCurrentDateTime, respectively. In addition, when you have a date-time fee in the widespread XSD format, you can convert it to characters greater suitable for output via calling the Oracle BPEL XPath characteristic formatDate.

In the next instance, the formatDate characteristic converts the date-time cost furnished in XSD layout to the string 'Jun 10, 2005' (and assigns it to the string subject formattedDate).

Question 26. Explain Bpelx:rename And Xsd Type Casting?

Answer :

The bpelx:rename extension in an assign activity enables a BPEL system to rename an element thru use of XSD kind casting.

The syntax of bpelx:target is similar to and a subset of to-spec for the reproduction operation. The goal should return a listing of 1 more detail nodes. Otherwise, a bpel:selectionFailure fault is generated. The element nodes detailed in the from-spec are renamed the QName targeted via the elementTo characteristic. The xsi:type characteristic is added to the ones detail nodes to cast those factors to the QName kind exact by way of the typeCastTo characteristic.

Assume you have the following employee list:

JohnDole
JaneDole
PeterSmith
MarySmith

Promotion modifications are actually applied to Peter Smith within the employee listing:

After executing the above casting (renaming), the facts appears as follows with xsi:type information introduced to Peter Smith:

JohnDole
JaneDole
3000
marysmith

The employee facts of Peter Smith is now invalid, because and are lacking. Therefore, is used to feature that statistics.

2500
petersmith
2500

Question 27. Explain Bpelx:do away with Extension In An Assign Activity?

Answer :

The bpelx: get rid of extension in an assign pastime allows a BPEL manner to cast off a variable.

Node removal distinctive by way of the XPath expression is supported. Nodes certain through the XPath expression may be more than one, but must be L-Values. Nodes being eliminated from this figure may be text nodes, characteristic nodes, and element nodes.

The XPath expression can return one or extra nodes. If the XPath expression returns 0 nodes, then a bpel:selectionFailure fault is generated.

The syntax of bpelx: goal is similar to and a subset of to-spec for the copy operation.

The following example shows addrVar with the following value:

500 Oracle Parkway 
Mailstop 1op6
CA
94065

After executing the following syntax within the BPEL manner document, the second one deal with line of Mailstop is eliminated.

Question 28. List Some Bpelx Extension Types To Perform Various Operations On Xml Data In Assign Activities?

Answer :

You may want to carry out diverse operations on XML statistics in assign activities.

The following bpelx extension kinds offer this functionality:

bpelx:append 
bpelx:insertBefore
bpelx:insertAfter
bpelx:get rid of
bpelx:rename and XSD Type Casting
bpelx:copyList
Question 29. What Are Two Audit Trial Tables Used In Bpel?

Answer :

There are 2 audit trail tables used in BPEL: audit_trail and audit_details.

All audit trail events are inserted into audit_trail. Audit_details is used for the info section of an occasion (ie. Payload); if a payload exceeds a certain length, it is inserted into audit_details as opposed to being inlined within the audit_trail occasion.

Question 30. Bpel Is Cross-platform, But Is There Any Advantage To Building The Underlying Services On A J2ee Platform? If So, What Are They?

Answer :

The J2EE platform is maturing towards better aid for clustering, Virtualization and monitoring. By structure the BPEL Process Manager as a hard and fast of J2EE components, we are able to transparently leverage those competencies. Virtualization, automated deployment, on-demand scalability, and self-healing are notions that marry very well with business procedures so it'll be very thrilling to peer the ones tendencies come together.

Question 31. How Important Is .Net Compatibility? To What Extent Does Bpel Process Manager Support It?

Answer :

.NET might be fourth or fifth at the listing of systems clients want to integrate with, so it within reason essential. The BPEL Process Manager ships with examples showcasing how a BPEL method can invoke a .NET provider in addition to how a .NET purchaser can provoke a BPEL manner. We are searching at extending the ones samples to demonstrate safety and reliable messaging.

Question 32. What Version Of The Bpel Standard Is Supported By Oracle Bpel Process Manager?

Answer :

BPEL PM 10.1.2 and 10.1.3 helps BPEL4WS 1.1. However, some functions from WSBPEL 2.Zero working draft have already been implemented in the BPEL PM 10.1.2 and 10.1.3 releases. We plan for complete assist for BPEL 2.Zero rapidly after it's far released and assume a clean migration course.

Question 33. Bpel Process Manager (as Well As Jdev, Adf, Toplink, Etc.) Run On Any J2ee Servers. Why Is Oracle So Committed To Open Standards And Open Interfaces?

Answer :

Because they are top for Oracle in that they allow us to leverage the masses of guy-years invested in building a scalable and dependable container. And they are precise for our clients in that they prevent them from being locked in.

Answer :

Oracle is a completely energetic member of the OASIS BPEL committee. With greater than 6,500 builders using the BPEL Process Manager, we are at the forefront of the adoption of BPEL and can circle lower back the comments we are amassing to the committee. Oracle is also actively concerned of peripheral specifications: WS-reliability, WS-message transport, WS-context, WS-safety, JSR-208/Java commercial enterprise integration. All those standards are coming together to convert the internet right into a messaging/integration backbone. They will consequently play a totally crucial position inside the adoption of BPEL.

Question 35. How Will Oracle Business Integration Take Advantage Of Bpel And Bpel Process Manager Going Forward?

Answer :

SOA, BPEL, and composite applications bring us one step closer to "real-time organisation." We agree with that wealthy business hobby tracking is the next step as it offers information visibility into the execution of move-functional tactics and a platform of enterprise system optimization. You need to count on to look loads greater from Oracle on that thing of the answer going forward.

Question 36. Why Is Native Bpel Important? What Is The Disadvantage Of Products That Only Import/export Bpel?

Answer :

Historically each time a wellknown has been followed (SQL, J2EE, LDAP, SMTP/POP/IMAP, HTML, and many others.), local answers have won. It is due to the fact native answers are much less complex, quicker and provide richer capability. It is also due to the fact re-architecting an engine round a brand new abstraction may be very hard, mainly if you have an present installation base that you want to keep and evolve in parallel.

Question 37. What Exactly Is Oracle Bpel Process Manager? What Is It Composed Of? How Does It Relate To The Rest Of The Stack?

Answer :

The Oracle BPEL Process Manager is a new addition to the Oracle product portfolio. It enables corporations to version, set up and control BPEL techniques. It comprises an smooth-to-use BPEL modeler, a scalable BPEL engine, an extensible WSDL binding framework, a monitoring console and a fixed of integrated integration services (transformation, user mission, java embedding). It makes BPEL/Web provider orchestration a first elegance citizen of the Java platform.

Question 38. What Is Orchestration? What Does It Mean To Build Composite Applications? Why Would Anyone Want To?

Answer :

Existing systems are not going away. Yet businesses need to construct new packages that could leverage the capability encapsulated in those existing systems. The belief of a composite application is primarily based around the concept of constructing new applications by way of wiring collectively present constructing blocks. Orchestration performs an essential role on this image because it's miles the glue that coordinates the execution of each discrete provider. A right orchestration server needs to be reliable, scalable and render the BPEL manner common sense with very high fidelity.

Question 39. What Is/become The Motivation Behind Bpel? How Does It Differ From Other/beyond Attempts/technologies Aimed At The Integration/enterprise Process Problem? Can You Talk Briefly About The Evolution Of Bpel?

Answer :

Orchestrating a set of offerings into an stop-to-end system waft involves a new set of technical necessities (binding to heterogeneous machine, synchronous and asynchronous message change patterns, facts manipulation, flow coordination, exception management, undeterministic occasions, compensating transactions, facet-by way of-side versioning, in-flight example control and auditing). The aim of BPEL is provide a richer and yet easier abstraction/popular for addressing those necessities. Although it's far a reasonably new preferred, it leverages from 10+ years of studies and development Microsoft and IBM invested in XLANG and WSFL.

Question 40. What Is Bpel? How Does It Relate To Web Services And Service-orientated Architecture (soa)?

Answer :

There is a consistent stress for organizations to interconnect their packages. This is what's driving the adoption of net services and SOA as an agency blue print for lowering the cost and complexity of integration projects. Making net services paintings is a -step system: first you put up and then you orchestrate. Publish way taking a part of a present device and exposing it as a service. Orchestrate approach composing multiple discrete services into an end-to-give up process drift. BPEL is the enterprise wellknown for orchestration.
