Interview Questions.

Q1. How Important Is .Internet Compatibility? To What Extent Does Bpel Process Manager Support It?

.NET might be fourth or 5th on the list of structures customers need to combine with, so it in all fairness important. The BPEL Process Manager ships with examples showcasing how a BPEL manner can invoke a .NET carrier in addition to how a .NET client can provoke a BPEL system. We are looking at extending the ones samples to demonstrate protection and dependable messaging.

Q2. Explain Orchestration And Choreography?

In orchestration, that is generally utilized in non-public enterprise tactics, a important process (which may be every other Web service) takes manipulate of the concerned Web offerings and coordinates the execution of various operations at the Web services concerned within the operation. The worried Web services do not "understand" (and do now not want to recognise) that they are involved in a composition manner and that they may be taking component in a higher-degree commercial enterprise manner. Only the principal coordinator of the orchestration is privy to this goal, so the orchestration is centralized with specific definitions of operations and the order of invocation of Web services.

Choreography, in evaluation, does no longer depend upon a critical coordinator. Rather, every Web provider concerned within the choreography is aware of precisely while to execute its operations and with whom to engage. Choreography is a collaborative attempt focusing on the trade of messages in public enterprise procedures. All members within the choreography need to be aware of the enterprise technique, operations to execute, messages to trade, and the timing of message exchanges.

Q3. What Are Two Ways Of Combining Web Services?

Web offerings can be mixed in two ways:

Orchestration

Choreography

Q4. What Is Bpel?

Within the organization, BPEL is used to standardize company utility integration in addition to to increase the combination to previously isolated structures. Between companies, BPEL permits easier and more effective integration with commercial enterprise companions. BPEL stimulates enterprises to similarly outline their enterprise approaches, which in flip results in commercial enterprise system optimization, reengineering, and the choice of the most appropriate methods, for that reason similarly optimizing the business enterprise.

Definitions of commercial enterprise tactics described in BPEL do now not affect current systems, thereby stimulating improvements. BPEL is the key technology in environments where functionalities are already or might be exposed through Web services. With increases within the use of Web offerings, the importance of BPEL will boom as nicely.

BPEL represents a convergence of two early workflow languages; Web Services Flow Language (WSFL) and XLANG. WSFL was designed by using IBM and is based on the concept of directed graphs. XLANG, a block-established language, turned into designed with the aid of Microsoft. BPEL combines both processes and offers a wealthy vocabulary for description of commercial enterprise tactics.

Q5. What Version Of The Bpel Standard Is Supported By Oracle Bpel Process Manager?

BPEL PM 10.1.2 and 10.1.3 helps BPEL4WS 1.@However, some features from WSBPEL 2.0 working draft have already been implemented in the BPEL PM 10.1.2 and 10.1.3 releases. We plan for full guide for BPEL 2.0 quickly after it's far released and anticipate a smooth migration course.

Q6. Explain The Use Of Message Event And Alarm Events?

Managing message occasions is specifically crucial whilst the commercial enterprise manner is looking ahead to callbacks from accomplice Web offerings. Hobby, lets you watch for best a single (exactly precise) message on a port type. Often, however, it is more useful to look ahead to a couple of message, of which best one will occur.

Alarm occasions are useful while you need the method to look forward to a callback for a positive time period, consisting of 15 mins. If no callback is obtained, the manner go with the flow continues as designed. This technique is in particular useful in loosely coupled carrier-orientated architectures, where you cannot rely upon Web offerings being to be had all of the time. This way, the system drift can continue even if one of the bookstores does no longer go back a proposal.

Q7. How Has/is Oracle Been Involved With The Evolution And Standardization Of The Bpel Spec? How Does This Relate To Oracle Other Integration And Web Service-associated Standards Efforts?

Oracle is a completely energetic member of the OASIS BPEL committee. With extra than 6,500 builders using the BPEL Process Manager, we're at the forefront of the adoption of BPEL and can circle back the comments we're collecting to the committee. Oracle is also actively involved of peripheral specs: WS-reliability, WS-message transport, WS-context, WS-safety, JSR-208/Java enterprise integration. All these standards are coming collectively to trform the net into a messaging/integration backbone. They will consequently play a very critical position in the adoption of BPEL.

Q8. Explain Pick Activity Of Bpel?

BPEL gives the hobby, via which you may specify that the business method must wait for the incidence of 1 occasion in a fixed of activities. Events can be message activities dealt with with the interest or alarm events handled with the pastime. For each event, you specify an pastime or a fixed of sports that ought to be achieved.

Q9. 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?

Because they are proper for Oracle in that they permit us to leverage the hundreds of man-years invested in building a scalable and dependable field. And they're desirable for our clients in that they prevent them from being locked in.

Q10. How Can You Assign The Current Value Of A Date Or Time Field By Using The Oracle Bpel Xpath Function Getcurrentdate, Getcurrenttime, Or Getcurrentdatetime ?

You can assign the modern-day cost of a date or time subject with the aid of using the Oracle BPEL XPath function getCurrentDate, getCurrentTime, or getCurrentDateTime, respectively. In addition, if you have a date-time cost in the standard XSD format, you could convert it to characters greater appropriate for output by using calling the Oracle BPEL XPath function formatDate.

In the next example, the formatDate function converts the date-time fee provided in XSD format to the string 'Jun 10, 2005' (and assigns it to the string subject formattedDate).

Q11. Bpel Is Cross-platform, But Is There Any Advantage To Building The Underlying Services On A J2ee Platform? If So, What Are They?

The J2EE platform is maturing closer to better support for clustering, Virtualization and monitoring. By structure the BPEL Process Manager as a fixed of J2EE components, we are able to trparently leverage the ones capabilities. Virtualization, automatic deployment, on-call for scalability, and self-recovery are notions that marry very well with enterprise techniques so it is going to be very interesting to look the ones traits come together.

Q12. What Is/was The Motivation Behind Bpel? How Does It Differ From Other/beyond Attempts/technologies Aimed At The Integration/commercial enterprise Process Problem? Can You Talk Briefly About The Evolution Of Bpel?

Orchestrating a fixed of offerings into an give up-to-cease method waft includes a new set of technical necessities (binding to heterogeneous system, synchronous and asynchronous message change styles, data manipulation, float coordination, exception control, undeterministic activities, compensating tractions, side-by way of-facet versioning, in-flight instance control and auditing). The intention of BPEL is provide a richer and yet less complicated abstraction/wellknown for addressing those requirements. Although it is a reasonably new preferred, it leverages from 10+ years of research and improvement Microsoft and IBM invested in XLANG and WSFL.

Q13. What Is Scopes In Bpel? How Can It Be Useful In Handling Faults?

Scopes are hierarchically organized components into which a complex commercial enterprise process may be divided. They provide behavioral contexts for sports. In other words, scopes permit you to define different fault handlers for different sports (or sets of activities gathered under a not unusual based pastime such as or ). In addition to defining fault handlers, you can declare variables that are seen simplest inside a scope. Scopes additionally can help you define nearby correlation units, compensation handlers, and event handlers.

Q14. What Is The Use Of Bpel Business Process?

In an ordinary scenario, the BPEL business procedure receives a request. To fulfill it, the process invokes the involved Web offerings after which responds to the unique caller. Because the BPEL manner communicates with other Web offerings, it is predicated closely on the WSDL description of the Web offerings invoked by the composite Web carrier.

Q15. What Are Two Audit Trial Tables Used In Bpel?

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

All audit path activities are inserted into audit_trail. Audit_details is used for the info phase of an occasion (ie. Payload); if a payload exceeds a sure size, it's far inserted into audit_details in place of being inlined inside the audit_trail event.

Q16. Explain Bpelx:insertbefore Extension In An Assign Activity?

The from-spec question within bpelx:insertBefore yields zero or extra nodes. The node listing is appended as baby nodes to the target node particular by means of the to-spec question.

The to-spec query of the insertBefore operation points to at least one or more single L-Value nodes. If a couple of node is back, the primary node is used because the reference node. The reference node have to be an detail node. The figure of the reference node should additionally be an detail node. Otherwise, a bpel:selectionFailure fault is generated. The node list generated by means of the from-spec question choice is inserted earlier than the reference node. The to-spec query can not consult with a partner link.

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

CA

94065

After the execution of the following syntax within the BPEL method record:

Redwood Shore> 

The price of addrVar now turns into:

Redwood Shore

CA

94065

Q17. How Can You Increase Performance In Bpel?

We can growth the overall performance by way of writing indexes and sequences. (Or) Go to application server - Configurations - Change Xml document

Q18. What Are Two Configuration Settings For Auditing?

AuditLevel:  

off - in reality no logging performed whatsoever; may also result in a slight overall performance raise for processing instances.

Minimum - all activities are logged; but, no audit info are logged.

Manufacturing - all events are logged. The audit information for assign activities are not logged; the information for all other nodes are logged.

Improvement - all occasions are logged; all audit info for all sports are logged.

AuditDetailThreshold: 

The maximum length (in bytes) an audit trail info string may be earlier than it is stored one after the other from the audit trail. If a details string is larger than the edge it will not be right now loaded when the audit trail is first of all retrieved; a link will be displayed with the scale of the info string. Typically, the details string will contain the contents of a BPEL variable. In cases wherein the variable is very massive overall performance can be significantly impacted via logging it to the audit trail. The default cost is 50 kilobytes.

Q19. How Many Tables Are Used For Mediator Instance Tracking?

There are in general 5 tables which might be utilized by mediator instance monitoring:

Mediator_instance - One row for every mediator message glide.

Mediator_case_instance - One row for every mediator case (~ routing rule).

If a mediator element has  routing rules then this ought to have 2 statistics for that mediator example.

Mediator_case_detail - Captures mediator audit trail for each mediator routing rule. Number of records may vary based totally on the nature of mediator factor.

Eg: if mediator factor is having a async req-resp routing rule then this would comprise 2 rows for the corresponding mediator routing rule.

Mediator_document - Stores the payload for routing regulations that are configured as deferred (~ parallel in jdev). So if all the routing rules are "sequential" then this will no longer include any data.

Mediator_audit_document - Stores the payload for audit path and best whilst "instanceTrackingLevel" for mediator is "Complete".

Q20. How Xml Data Works In Bpel?

In a BPEL system, every piece of information is in XML bureaucracy. This includes the messages handed to and from the BPEL procedure, the messages exchanged with external offerings, and neighborhood variables used by the method. You define the kinds for these messages and variables with the XML schema, generally within the WSDL record for the go with the flow, the WSDL files for the offerings it invokes, or the XSD file referenced with the aid of those WSDL documents. Therefore, all variables in BPEL are XML statistics, and any BPEL manner uses a good deal of its code to manipulate these XML variables. This normally includes acting facts trformation among representations required for exclusive services, and nearby manipulation of facts (as an example, to combine the effects from several provider invocations).

Q21. How Can We Use Pick As Initial Activity?

You can use the pastime instead of the initial interest. You can specify several operations, and receiving any such messages will bring about the introduction of a business technique example. Then you have to use a unique shape of the interest. You specify the createInstance attribute for the hobby, however you could specify best occasions; events are not authorized on this particular form.

To apprehend the usage of this unique form of the pastime, recollect the bookstall Web provider, carried out as a simple BPEL system.

Q22. What Is Bpel Process In Soa ?

(Business Process Execution Language) BPEL Process is a language used for the composition, orchestration and coordination of webservics. In this post we can provide an explanation for BPEL, define the BPEL role with regard to Service Oriented Architecture and provide an explanation for the manner-orientated approach to SOA and the function of BPEL.

In BPEL the Enterprise application and statistics systems have grow to be more extra fundamental property to businesses. The Companies are accept as true with on them so as to carry out business operations.

Enterprise Information system can enhance the performance of businesses thru the automation of commercial enterprise methods. The objective of just about each enterprise is that the software it makes use of have to provide comprehensive help for enterprise techniques. It me that programs have to align with enterprise methods closely.

BPEL Role of commercial enterprise techniques and their demanding situations,BPEL Business and IT alignment,What are BPEL functions,what are BPEL capabilities, BPEL Orchestration and Choreography, Examine the relation of BPEL to different Languages, The destiny of BPEL.

Already present packages have often been evolved the usage of older technology, languages and architectures, which are by means of definition much less flexible to change. Such C,C++, and Mainframe. These programs are tightly coupled packages, built of interrelated modules, those are can not be differentiated, upgraded, or refactored with affordable amount of effort, region important limitations on the flexibility of such applications.

Already current programs are also difficult to modify and adapt due to the fact they have not been evolved in a bendy manner that would permit enhancing application elements speedy and efficaciously. Modifying current applications are require extra time Complexity of present programs and the overall IT Architecture, Modifying them is a complicated, difficult and time-ingesting venture.

Q23. How Will Oracle Business Integration Take Advantage Of Bpel And Bpel Process Manager Going Forward?

SOA, BPEL, and composite programs convey us one step in the direction of "real-time corporation." We consider that wealthy enterprise activity monitoring is the subsequent step because it offers details visibility into the execution of cross-useful procedures and a platform of enterprise method optimization. You must expect to see a lot greater from Oracle on that element of the solution going forward.

Q24. What Are Two Different Ways Of Describing Business Processes That Are Supported By Bpel?

BPEL supports  distinctive methods of describing enterprise processes that support orchestration and choreography:

 Executable methods allow you to specify the exact info of commercial enterprise processes. They observe the orchestration paradigm and may be carried out through an orchestration engine.

Abstract business protocols permit specification of the public message trade among parties only. They do now not encompass the inner info of process flows and are not executable. They follow the choreography paradigm.

Q25. Why Is Native Bpel Important? What Is The Disadvantage Of Products That Only Import/export Bpel?

Historically whenever a standard has been adopted (SQL, J2EE, LDAP, SMTP/POP/IMAP, HTML, and many others.), native solutions have gained. It is because native solutions are much less complicated, faster and offer richer functionality. It is likewise because re-architecting an engine around a new abstraction could be very difficult, in particular when you have an existing deploy base that you need to hold and evolve in parallel.

Q26. Explain Bpelx:rename And Xsd Type Casting?

The bpelx:rename extension in an assign hobby enables a BPEL process to rename an element via use of XSD type casting.

The syntax of bpelx:goal is similar to and a subset of to-spec for the reproduction operation. The goal should go back a list of 1 greater element nodes. Otherwise, a bpel:selectionFailure fault is generated. The element nodes special in the from-spec are renamed the QName specified via the elementTo characteristic. The xsi:kind characteristic is added to those element nodes to cast the ones factors to the QName kind targeted through the typeCastTo attribute.

Assume you have got the subsequent employee listing:

JohnDole

JaneDole

PeterSmith

MarySmith

Promotion changes are actually implemented to Peter Smith within the worker list:

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

JohnDole

JaneDole

3000

marysmith

The worker statistics of Peter Smith is now invalid, due to the fact and are lacking. Therefore, is used to add that information.

2500

petersmith

2500

Q27. What Is Bpel? How Does It Relate To Web Services And Service-orientated Architecture (soa)?

There is a consistent stress for corporations to interconnect their applications. This is what is riding the adoption of internet services and SOA as an agency blue print for decreasing the price and complexity of integration tasks. Making net offerings work is a -step technique: first you put up and then you definately orchestrate. Publish me taking a part of a current gadget and exposing it as a service. Orchestrate me composing multiple discrete services into an quit-to-give up procedure waft. BPEL is the enterprise standard for orchestration.

Q28. What Are Two Types Of Events Supported By Bpel?

Although fault handlers and scopes improve the robustness of BPEL methods significantly, you could also control occasions.

BPEL supports two types of activities:

Message events are brought about by way of incoming messages thru operation invocation on port kinds.

Alarm occasions are time-associated and are prompted both after a positive length or at a specific time.

Q29. What Is Use Of Assign Activity In Bpel?

You use the assign activity to duplicate facts from one XML variable to some other, or to calculate the fee of an expression and keep it in a variable. A replica detail in the hobby specifies the source and target of the task (what to copy from and to), which should be of well matched types. 

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

popular-factors 

+

from-spec

to-spec

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

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

You can assign numeric values in XPath expressions. The following example suggests how to assign an XPath expression with the integer fee 100.

Q30. How Can A Business Process Signal A Fault Explicitly?

A enterprise process sometimes desires to sign a fault explicitly. Therefore, BPEL presents the activity, which has the following syntax:

BPEL does not require definition of fault names previous to their use inside the interest. This flexible method can be blunders-prone, due to the fact there's no compile-time checking of fault names. In the case of typos, misspelled faults will no longer be treated by way of the detailed fault handler.

Faults can also have an related variable that includes fault records. If one of these variable is required, you need to specify it while throwing a fault, via using the non-obligatory faultVariable

Q31. What Are Various Sources Of Faults In Bpel?

Business techniques specified in BPEL will interact with partner processes thru operation invocations on Web services. The verbal exchange between Web services is generally over net connections that are not fairly reliable. Web services can also boost faults because of logical and execution mistakes. Therefore, BPEL commercial enterprise techniques want to address faults correctly and can additionally need to signal faults themselves.

Faults in BPEL can be from various sources:

A BPEL procedure can explicitly signal (throw) a fault.

A fault can occur while the BPEL technique invokes a Web service operation. The operation might go back a WSDL fault message, which results in a BPEL fault.

A fault can be thrown routinely by means of the BPEL runtime surroundings, both due to a positive situation within the BPEL system itself (including a be a part of failure), due to blunders conditions in the runtime environment, or related to community verbal exchange or different motives. For such situations, BPEL defines several widespread faults.

Q32. What Is Inline Fault Handling?

In BPEL tactics, invocation of operations on Web services can be in particular error-prone. There are severa situations—consisting of broken connections, unavailability of Web offerings, or modifications within the Web services WSDL—that can save you a BPEL procedure from efficaciously invoking a partner Web service operation.

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

Q33. How Can We Handle Faults In Bpel?

When a fault takes place inside a enterprise process, the manner won't entire effectively. (But it could whole effectively if the fault is dealt with inside a scope, which allows you to divide a complex technique into numerous components; more on scopes later.) The commercial enterprise procedure can deal with the fault via one or more fault handlers. Within a fault handler, the commercial enterprise manner defines custom sports that should get over the fault and possibly opposite the partial (unsuccessful) paintings of the activity wherein the fault has came about.

The fault handlers are targeted earlier than the primary interest of the BPEL manner, after associate hyperlinks and variables.

The average shape is shown inside the following code excerpt:

Within the fault handlers, you specify numerous activities wherein you imply which fault you want to seize and take care of. Within a fault handler, you have to specify at the least one or . The interest may be distinct only once within a fault handler.

Usually you specify numerous sports where you will cope with unique faults and use to deal with all other faults. To specify which fault you would love to address, you need to specify at the least one of the following:

faultName, which specifies the name of the fault to address

faultVariable, which specifies the variable type used for fault information

The flexibility of activities is high, and all of the following variations are permissible:

Fault handlers in BPEL are much like attempt/seize clauses in contemporary programming languages consisting of Java.

Q34. What Is Orchestration? What Does It Mean To Build Composite Applications? Why Would Anyone Want To?

Existing systems aren't going away. Yet organizations want to build new programs that may leverage the functionality encapsulated in the ones current structures. The notion of a composite utility is based around the idea of constructing new applications through wiring collectively current constructing blocks. Orchestration performs an crucial function on this photo because it's far the glue that coordinates the execution of each discrete service. A proper orchestration server wishes to be dependable, scalable and render the BPEL manner good judgment with very high constancy.

Q35. Explain Bpelx:take away Extension In An Assign Activity?

The bpelx: eliminate extension in an assign pastime allows a BPEL method to remove a variable.

Node removal distinct via the XPath expression is supported. Nodes detailed by means of the XPath expression can be multiple, but must be L-Values. Nodes being eliminated from this parent can be text nodes, attribute nodes, and element nodes.

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

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

The following example shows addrVar with the following cost:

500 Oracle Parkway 

Mailstop 1op6

CA

94065

After executing the following syntax in the BPEL technique report, the second one cope with line of Mailstop is eliminated.

Q36. What Exactly Is Oracle Bpel Process Manager? What Is It Composed Of? How Does It Relate To The Rest Of The Stack?

The Oracle BPEL Process Manager is a brand new addition to the Oracle product portfolio. It allows firms to version, set up and manipulate BPEL approaches. It comprises an clean-to-use BPEL modeler, a scalable BPEL engine, an extensible WSDL binding framework, a tracking console and a fixed of integrated integration offerings (trformation, user venture, java embedding). It makes BPEL/Web service orchestration a first magnificence citizen of the Java platform.

Q37. How Can You Assign Boolean Values To A Field In Xpath Expression ?

In this situation of assigning Boolean values, the XPath expression within the from clause is a name to XPath's Boolean function true, and the specified accredited subject is set to proper. The characteristic fake is also to be had.

The XPath specification recommends that you use the "actual()" and "fake()" functions as a technique for returning Boolean constant values.

If you as an alternative use "boolean(actual)" or "boolean(false)", the authentic or fake inside the Boolean characteristic is interpreted as a relative element step, and now not as any true or fake steady. This me it tries to pick a toddler node named authentic below the present day XPath context node. In most cases, the proper node does now not exist. Therefore, an empty result node set is back and the boolean() feature in XPath 1.Zero converts an empty node set right into a fake end result. This result may be probably confusing.

Q38. What Is Oracle Jdeveloper?

Oracle BPEL Process Manager gives assist for the use of Oracle JDeveloper to graphically layout BPEL approaches. 

Oracle JDeveloper is an included development surroundings (IDE) for building applications and Web services the usage of Java, XML, and SQL standards. Oracle JDeveloper supports the entire improvement life cycle with integrated capabilities for designing, coding, debugging, testing, profiling, tuning, and deploying applications. A visible and declarative improvement approach and the Oracle Application Development Framework (ADF) work collectively to simplify application improvement and reduce coding responsibilities.

Oracle JDeveloper uses BPEL as its local layout. This me that techniques constructed with Oracle JDeveloper are 100% transportable. Oracle JDeveloper additionally allows you to view and adjust the BPEL supply with out decreasing the usefulness of the tool.

You design BPEL approaches via dragging and losing factors (referred to as sports) into the system and enhancing their belongings pages. This removes the need to write down BPEL code. You integrate BPEL methods with external services (known as accomplice hyperlinks). You additionally integrate adapters and services together with workflows, trformations, notifications, sensors, worklist project control, and enterprise regulations with the technique. Oracle JDeveloper can installation the evolved processes immediately to Oracle BPEL Server. This facilitates the development and renovation of BPEL procedures.

Oracle BPEL Process Manager presents guide for the following offerings and adapters in Oracle JDeveloper:

Trformations, workflows, worklists, notifications, sensors, and enterprise rules

Technology adapters (document, FTP, database, AQ, JMS, MQ, and Oracle Applications)

Q39. What Are Predefined Errors In Bpel?

Custom mistakes

Timed out mistakes

BPM mistakes

Validation Errors

Q40. What Are Two Modes Of Invocation That Are Supported By Bpel Console?

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

The XML Source mode, shown beneath, permits you to enter XML source facts without delay into a textual content shape and that source is passed, as is, to initiate the BPEL method. To simplify the usage of this mode, you may configure default XML information in the deployment descriptor of the system, which will be pre-loaded into the XML statistics field .

Alternatively, the HTML Form view within the BPEL Console's Initiate tab will routinely generate an HTML enter shape (while viable), which may be used to offer the enter values to initiate a BPEL method for checking out functions.

Q41. List Some Bpelx Extension Types To Perform Various Operations On Xml Data In Assign Activities?

You may additionally need to perform numerous operations on XML facts in assign activities.

The following bpelx extension types offer this capability:

bpelx:append 

bpelx:insertBefore

bpelx:insertAfter

bpelx:remove

bpelx:rename and XSD Type Casting

bpelx:copyList

Q42. List Of All Primitive Activities Supported By Bpel Business Process?

Primitive activities represent simple constructs and are used for not unusual responsibilities, consisting of the following:

Invoking different Web services.

Waiting for the client to invoke the business system via sending a message.

Generating a response for synchronous operations.

Manipulating facts variables.

Indicating faults and exceptions.

Waiting for some time.

Terminating the entire manner.

Q43. What Are Alerts For Stuck Bpel Messages?

An alert is displayed when there are caught messages for asynchronous BPEL techniques. A international time threshold is used become aware of stuck messages.

Alerts are displayed at more than one levels:

soa-infra

Composite

Flow Trace (PS4)
