Interview Questions.

Q1. Explain About Routing?

Routing is specifically used to assign challenge to Particular Participant or Particular institution. Same participant appearing one or more tasks.( Or) Assigning equal participant to 1 or extra activities.

Q2. How Do You Access A Child Coach View?

Context.GetSubview(viewId, requiredOrder)

Accesses a subview instance given the subview ID. This technique is similar tocontext.Subview[viewid] except that the return fee is an array of subview instances.

ViewId(String) – the view ID or manage ID of the subview

requiredOrder (boolean) – (optional) shows whether the array back desires to maintain the equal order as within the DOM tree. The default cost is false.

The name this.Context.GetSubview(“viewid”) returns an unsorted array of subview items. The call this.Context.GetSubview(“viewid”, fake) returns precisely same array.

The best distinction between the two calls and the characteristic callthis.Context.GetSubview(“viewid”, genuine) is thatthis.Context.GetSubview(“viewid”, actual) returns an array of subview items whose order suits the order of the DOM nodes in the DOM tree.

Q3. What Is Teamworks?

Teamworks is a BPM device advanced by using Lombardi Software.

Teamworks architecture allows all groups with with in your company to collaborate to layout and deploy green approaches.

Teamworks additionally lets in you to control and analyze process overall performance.

Teamworks is having Eclipse based totally Authoring Environment integrates together with your other improvement tools.

Q4. Explain About Sla?

SLA full shape is Service Level Agreement. It specially used to do paintings well timed way fashion Simply SLA is an Agreement Between Two People.

Q5. What Is Tracking? How Do You Enable It? What Are The Different Ways Of Tracking? What Happens When You Enable Tracking?

To create customized and 1/3-birthday celebration reviews in IBM® BPM, you want to pick out the records to track and send that statistics to the Performance Data Warehouse.

To track information in a business technique definition (BPD), use autotracking, monitoring companies, or each.

Autotracking:

routinely captures records from monitoring points at the entry and exit of each object in a BPD (for example, services, activities, and gateways).

To permit autotracking, make sure that Enable Auto Tracking is selected below the Tracking tab of the Business Process Diagram. (This is the default.)

Tracking corporations:

offer more manipulate over tracked records. For example, use tracking corporations tune a specific group of procedure variables throughout multiple BPDs or system packages and to save tracking factors for a timing c language.

To allow tracking corporations, ensure that Enable monitoring is chosen beneath the Overview tab of the Business Process Diagram. (By default, the checkbox is not checked.)

Note that the Enable tracking setting does not apply to services with monitoring factors. Tracking statistics is continually enabled when services include tracking factors.

You can take benefit of both monitoring strategies in a single BPD. If you use both autotracking and monitoring companies, you may create a timing c programming language.

After you configure facts monitoring on your BPD, and every time you sooner or later replace your information monitoring requirements, you have to ship the tracking definitions to the Business Performance Data Warehouse.

When you ship monitoring definitions, both directly or as part of a picture deployment, the Business Performance Data Warehouse establishes the shape in its database to keep the records that is generated through the Process Server whilst you run instances of your techniques.

In IBM BPM, these tracking necessities are referred to as definitions because they set up the database schema inside the Business Performance Data Warehouse to accommodate the tracked statistics generated by means of the Process Server.

Q6. What Is Uca? (underneath Cover Agent)

Under Cover Agents are used to send and obtain message with in teamwork’s. The body of the message is described by teamwork’s service that is connected to the UCA.

Q7. What Is Serialization?

Serialization is particularly used to convert the XML to the Teamwork’s Object.

When we use web carrier integration provider we can use serialization. The output of web carrier is XML So, we need to transform it to Team work’s Object.

Q8. What Is Intermediate Message Event Listener?

Intermediate message Event takes region in jogging Business procedure.

They inform the Business system to move a token forward in the manner.

An Intermediate listener flow ahead best if event output records fits with the co-relation statistics inside the commercial enterprise technique.

Q9. What Is Bpd?

To version a system, you have to create a enterprise procedure definition (BPD). A BPD is a reusable model of a technique, defining what is common to all runtime times of that technique model.

A Business Process Definition (BPD) can consist of a lane for each system or group of customers who participate in a system. A lane is the field for all of the sports to be completed by means of a specific organization of users or by a machine.

Q10. What Is Gateway? Or How Do You Converge Or Diverge The Process Flows? What Are Different Gateways Available And When Do You Use Each?

Gateways manipulate the divergence and convergence of a sequence go with the flow, figuring out branching and merging of the paths that a runtime process can take.

You can version the following varieties of gateways on your manner diagram:

Parallel (AND): Use a parallel, diverging gateway whilst you need the procedure to comply with all available paths.

Use a parallel, converging gateway when you want to converge all available paths.

Inclusive (OR): Use inclusive, diverging gateway while you want to follow one or more available paths based on situations which you specify.

Use downstream of an inclusive diverging gateway to converge multiple paths into a unmarried route after all the energetic paths completed their runtime execution. The inclusive join appears upstream at each route to determine whether the direction is lively, wherein case it waits. Otherwise, it passes the token through without ready.

Note: Inclusive gateways can observe a maximum of n–1 paths. So, in case you model a conditional break up with three paths, the method can comply with two of these paths

Exclusive (XOR): Use to version a factor within the procedure execution wherein handiest one among several paths can be observed, depending on a condition, or to model a point in manner execution while the token for one in every of several incoming paths is handed through the gateway.

Event: Use to model a point in the method execution where simplest one in all numerous paths can be accompanied, depending on events that arise. A particular occasion, including the receipt of a message or timer event, determines the direction to be taken. An event gateway have to be modeled a sure way as defined in Modeling occasion gateways.

Be aware about the following whilst the use of gateways:

After you drag a gateway from the palette for your process diagram, you could select any of the available gateway kinds.

When you version inclusive and one-of-a-kind gateways, if all conditions examine to fake, the technique follows the default sequence flow. The default series go with the flow is the primary sequence drift that you create from the gateway to a following interest, however you can exchange the default collection float at any time.

Q11. What Is A Coach?

Coach is a Human interest in BPM Lombardi. When we build human service We typically consist of Coaches.

Which provide the interface for the give up-person interaction.

Q12. How Do You Enable Javascript Debugging For The Coaches?

For debugging functions, you could set your Coaches and Coach Views to apply the readable variations of Dojo and the Coach framework JavaScript.

Open the executive console and click Resources > Resource Environment > Resource Environment Provider

On the Resource surroundings vendors web page, click on Mashups_ConfigService.

Under Additional Properties, click on Custom houses. The list of custom homes opens.

Click isDebug, change the Value field to genuine, and then click on OK.

Save your modifications to the grasp configuration.

Restart the application server example.

Q13. What Are Tracks? How Is It Different From A Versioning System Like Cvs?

Process Center tracks the adjustments in the procedure programs the usage of Snapshots.

Snapshots:

Record the state of the gadgets within a procedure utility or song at a selected factor in time.

From the Process Center console, you can create snapshots of your technique packages.

You also can install precise snapshots of your system applications on the Process Servers in staging, check, and production environments.

Tracks:

Optional subdivisions in a process application based on team responsibilities or system application versions.

You can determine if additional tracks are important for each procedure utility and, in that case, permit them at any time

Typically Tracks could be constituted of production snapshot for maintenance purposes.

Difference from versioning structures like CVS.

Unlike ordinary versioning structures, tracks or snapshots can not be merged in later point of time. So, It might be tough for parallel improvement.

Q14. How Do You Assign The Activities To Users?

For any pastime with a BPM carrier implementation, you can designate the users who acquire the runtime mission by the use of the Assignments web page within the houses for that hobby.

In the Designer view, click an hobby in a BPD diagram to show its residences.

Go to the Assignments web page in the residences view.

From the Assign To listing, pick one of the following options:

Last User in Lane:

Assigns the runtime mission to the user who completed the interest that right now precedes the chosen hobby within the swimlane.

Do now not pick out this option for the primary hobby in a lane until the pastime is a carrier in a top-level BPD and a Start Event is within the lane. In this case, the runtime venture is routed to the user who commenced the BPD.

Lane Participant:

Assigns the runtime task to the participant institution related to the swimlane wherein the selected pastime is positioned (the default choice).

Routing Policy:

Assigns the runtime mission in line with the policy that you set up.

List of Users:

Assigns the runtime undertaking to an ad hoc list of users.

Custom:

Assigns the runtime task according to the JavaScript expression that you offer inside the corresponding area. To select one or extra variables on your expression, click the variable choice icon next to the field.

The JavaScript expression produces consequences inclusive of USER:<user_name>, ROLE:<group_name>, or PG:<participant_group>, where user_name is the call of an IBM® BPM consumer (along with tw_author), group_name is the name of an IBM BPM protection group (consisting of tw_authors), and participant_group is the name of a group of users on your employer.

Q15. Explain The Difference Between The Coaches And Coach Views.?

Coaches include one or greater Coach Views. The Coach Views offer the consumer interface elements and format for the Coach.

Each Coach View can incorporate one or greater different Coach Views, which creates a parent-toddler dating among these Coach Views.

At run time, the parent Coach View is rendered as a <div></div> tag that incorporates a nested <div></div> tag for every child Coach View.

Each Coach View also can have a binding to a business object, CSS code to control its visible layout, and JavaScript to outline its behavior

Coach Views are reusable so you can create a library of common person interfaces and behavior. You can combine these common user interfaces to unexpectedly increase new Coaches.

The Coaches toolkit this is included with IBM BPM carries a set of commonplace user interfaces which can be called stock controls. You can include these stock controls while you are creating your own Coach Views.

Q16. What Is A Process In Ibm Bpm ?

A technique is sort of a Program that does works interior Teamworks. It has a place to begin and at the least one go out point.

Q17. What Is Tracking?

To track a particular cost for the duration of the manner we will use the tracking organization.

To tune a selected fee goes to Authoring surroundings. Then go to report option. Then select the option Send to performance facts warehouse alternative.

Q18. What Is Event Listener?

An event listener is a widget this is provides to our BPD. It basically tells our technique to do some thing if an event occurs.

An occasion is some thing that can appear outside our procedure or in our technique that outcomes how our process runs.

Event listener can not be added to provider layer. Presently they're used in our commercial enterprise process layer.

Q19. How Do You Enable Uca To Start A Bpd?

If you want to run the startBpdWithName utility programming interface (API) to begin a BPD example inner an secret agent, set the <enable-start-bpd-from-uca> property to real in the 100Custom.Xml report or another override file.

Restart the product, and test the TeamworksConfiguration.Going for walks.Xml record to make certain that the putting has the correct cost. The assets is set to fake via default, and if you don’t trade it, you might have mistakes that save you the BPD from starting.

Q20. How A Bpd Can Be Divided Into?

The BPD can be divided into Lanes and Milestones. The horizontal strains are referred to as Lanes and vertical ones are referred to as Milestones.

Q21. Explain About Reports?

We want to report the facts in specific codecs Ex: Bar graph, Pie graph, and so forth…

Reports were displayed using Score boards.

Adhoc Reports: To create reviews at any time.

Q22. How Do You Perform Validation On Coach Views?

To validate the facts this is in the Coach earlier than the float proceeds to the following step in the provider glide, upload a validation node to the drift. The validation node can be a nested provider or a server script. The server script is the simpler implementation although the nested carrier gives greater flexibility.

Example server script:

tw.Local.Validate = new tw.Item.CoachValidation();

if (tw.Neighborhood.Utility.Call == “”)

tw.Device.AddCoachValidationError(tw.Local.Validate, “tw.Local.Software.Call”,

“The call cannot be empty.”);

 

Q23. How Do You Generate A Unique Id For A Coach View At Runtime?

In a few conditions you might need to apply the ID attribute on your DOM factors within a coach view. However, all DOM IDs should be globally particular.

For example: all through collaboration the default highlighting behavior is implemented based totally on a completely unique DOM ID. To ensure a completely unique ID, you may use the $$viewDOMID$$ placeholder key-word. At run time, this key-word will be replaced via the Coach View DOM ID.

Q24. How Do You Analyze The Time Elapsed Between The Activities In Process?

If you need to analyze the quantity of time that elapses among positive steps on your manner, you may upload tracking points in your BPD after which create atiming c programming language to capture the period between defined start and stop points. When you create a timing c language, you can create custom reports that enable you to calculate the duration of a technique, or examine the period of several processes.

Do the subsequent duties earlier than creating a timing interval:

Enable autotracking:

Add monitoring factors to the enterprise process definition

Create a monitoring institution to preserve the timing c programming language information (ensure to feature each tracking point to the tracking organization you created)

Q25. What Is Sub-method?

A subprocess represents a collection of logically associated steps contained within a parent method. You can view a subprocess as a unmarried interest, providing a simplified, excessive-degree view of the determine method, or you may drill into the subprocess for a extra particular view of its contents.

Subprocesses can comprise swimlanes which might be awesome from the figure method. For example, sports in your subprocess may be completed by means of a set of individuals this is different from the set of individuals that perform the activities in the discern method.

Like different sports, subprocesses may be configured to run more than one instances within the execution of the parent process via configuring looping conduct on the subprocess activity element inside the parent technique.

Q26. What Are Under Cover Agents (uca)?

An secret agent is began by way of an event. The occasion may be a message event, a content material occasion, or a timer occasion this is the end result of a specific agenda.

Message events can originate from a Business Process Diagram (BPD), from a web carrier which you create, or from a message that you publish to the JMS listener.

When an spy executes, it invokes an IBM Business Process Manager service or a BPD in reaction to the occasion.

When you include a message event or content event in a BPD, you have to attach an secret agent to the event. For instance, whilst a message event is received from an outside gadget, an secret agent is needed to cause the message event inside the BPD in reaction to the message.

Q27. How Will You Access Processes In Bpm?

You can Start, Stop, Control and Monitor Processes the usage of Process Portal.

Q28. What Are Different Task Types?

User Task:

User obligations should be finished by way of system contributors and are related to Human services via default.

For cases wherein you need a user to start the carrier however no additional user involvement is required, you can additionally pick a user assignment kind and partner a service with it, inclusive of an Integration or Advanced Integration service.

Process Designer automatically creates the specified consumer implementation which you need when you drag manner additives onto a diagram. You can also choose User Task and an related service for an pastime implementation, as defined in Implementing sports.

System Task:

System responsibilities have to be completed by means of an automated gadget or carrier and are robotically run with out a need for user initiation irrespective of the kind of lane wherein they may be defined in a BPD diagram.

When you drag an Ajax carrier, General System service, Integration service, or Advanced Integration service from the library to a BPD diagram, Process Designer robotically creates an activity with a System mission type, regardless of whether the service is dragged to a system lane or to a player lane.

Dragging an activity from the palette to a machine lane in a BPD diagram robotically creates an activity with a System venture with the Default System carrier decided on. System obligations that you vicinity in a non-gadget lane are also run via the machine.

Decision Task:

Decision duties are beneficial whilst you want a choice or condition in a business rule to decide which technique implementation is started out.

When you drag a Decision carrier from the library to a BPD diagram, Process Designer automatically creates an interest with a Decision challenge.

Q29. What Are Teamworks Components?

Shared Model : Stores all Process, Services,Performance Data,Business Events and Conditions.

Process Server: Executes the Process and Services that authors build the usage of Teamworks Authoring Environment.

Performance Server: Manages and combination Process Performance statistics and monitors business activities and situations.

Server Consoles: offer interfaces that enables administrator to configure and preserve the Process Server and performance Server other customers might also have restricted get right of entry to to change password and carry out different fundamental tasks.

Authoring Environment: Eclipse based totally improvement Environment consists of numerous interfaces that allow authors to Model, Simulate and Inspect methods. Available interfaces include Service Modeler, Process Inspector, Process Molder.

Process portal: Enables procedure contributors to carry out assigned challenge,view the records of venture,launch any methods or offerings that are attached to mission and look at the performance of their methods andteams.Tools available from the process portal include Scoreboards.

Q30. What Are Differences Between Coaches And Heritage Coaches?

@Coaches can incorporate a couple of Coach Views. Coach Views are reusable collection of user interfaces and can be certain to a information kind. They may be shared between the Coaches. But in Heritage Coaches, all UI elements need to be recreated.

@Coaches have net 2.0 appearance and behavior and  have customer aspect information model i.E. Statistics can be refreshed with out the total web page refresh. They use Dojo 1.7.3.

@Instead of the only-button mechanism of Heritage Coaches, Coach Views use named boundary occasions. Programmers use boundary activities for actions including information updates with the server and tritions to different Coaches or offerings

@Coaches guide collaboration while Heritage Coaches do now not. More than one individual can work on the identical Coach instance on the same time of their personal browsers

@The control ID of a view-based Coach is different from the control ID of a Heritage Coach. The control ID of a Heritage Coach is the div node ID. This isn't the case in view-primarily based Coaches because Coach Views are reusable and you can have multiple perspectives in a Coach.

In view-based Coaches, the control ID is the price of the facts-viewid characteristic of a <div></div> tag. By the usage of the data-viewid characteristic, View developers can find the nested View because information-viewid is unique inside its parent or enclosing view.

Coach can not comprise Heritage Coach factors and Heritage Coaches can not contain Coach Views. That is, a person interface should be a Coach or Heritage Coach and not a mix of the two.

Q31. What Is Durable Subscription?

When a message is sent to an user who is offline, the message waits in the queue and receives added whilst the consumer seems online again. This phenomenon is called as “Durable Subscription”.

Q32. What Are The Key Components Of Bpm?

Process Server

Process Designer

Process Center

Process Center Console

Performance Data Warehouse

Process Portal

Process Admin Console

Q33. What Are The Different Types Of Exceptions?

We can build errors managing competencies both in BPD degree and Service degree the usage of to be had Exception additives.

Exception’s In BPD Level:

Intermediate Exception event

End Exception Event

Exception’s In Service Level:

Catch Exception

Throw Exception

Q34. How Do You Fire A Boundary Event Pro-grammatically?

This.Context.Trigger(callback);

Q35. What Is An Activity In Ibm Bpm?

An Activity represents a logical unit of work that may be execute at run time by a Human or  System.

Q36. What Are Coaches?

Coaches are the consumer interfaces for human offerings.

There are two forms of person interfaces for human offerings: dashboards and undertaking completion. To build either type of consumer interface for human services, you operate Coaches.

When a Coach is a dashboard person interface, users can run it as a stand-by myself user interface at any time. The users get right of entry to it through the Process Portal.

When a Coach is a challenge of completion person interface, it's miles part of the human provider glide. At run time, while the waft enters the Coach, the person sees the consumer interface that is described for that Coach. The user interface includes HTML code that is displayed in a web browser. The flow leaves the Coach while a boundary occasion occurs. A Coach can have multiple go out flows with each one related to a different boundary occasion.

Q37. Explain About Durable?

Even although the patron is down message is with occasion supervisor. Then When the patron is up message is introduced.

Q38. What Are Different The Sub Process Types?

There are three types of subprocesses that you can version in a BPD. Their characteristics are defined within the following table.

Subprocess:

A non-reusable subprocess that exists only within the parent technique

Characteristics:

Each subprocess ought to include at the least one begin occasion with an implementation type of None.

Activity names need to be specific with appreciate to the top-stage system sports, and all different subprocesses and occasion subprocesses below the identical pinnacle-level manner.

Variable Scope:

Inherits variables from the parent process and may include local personal variables visible handiest inside the subprocess.

Variable names declared in a subprocess can't be similar to variable names declared in any of its figure approaches. If there are multiple layers of embedding, with subprocesses contained inside other subprocesses, variable names ought to be specific at some stage in the entire subprocess hierarchy.

Linked method:

A call to every other reusable method.

Characteristics:

The technique called by means of the related technique pastime can include multiple start occasions, but should contain at the least one begin occasion with an implementation sort of None.

Variable Scope:

Variable data is local to every process, consequently data mapping is needed to skip records into and out of the related procedure.

Event subprocess:

A specialised type of non-reusable subprocess that isn't always part of the normal collection float of its figure technique, and which might occur zero or normally throughout the execution of the discern system.

Characteristics

 

Must incorporate a unmarried begin event, which may be one among:

Timer

Message

Error

Event subprocess execution can interrupt determine manner or can run in parallel.

Activity names have to be specific with appreciate to the pinnacle-level method sports, and all different subprocesses and occasion subprocesses under the equal top-stage manner.

Boundary events are not supported on an occasion subprocess.

Variable Scope:

Inherits variables from the parent procedure and can contain neighborhood personal variables visible handiest within the subprocess.

Variable names declared in an event subprocess can not be the same as variable names declared in any of its determine approaches. If there are more than one layers of embedding, with event subprocesses contained inside other subprocesses, variable names should be specific throughout the whole subprocess hierarchy.

Q39. What Are Variables(business Objects) In Ibm Bpm?

Business gadgets are known as variables in Teamworks represent the information that provides the statistics that offers the enterprise context to a going for walks process. There are  varieties of variables -Simple And Complex variables have exclusive scopes- non-public Input and Output.

Q40. What Is Start Message Event Listener?

When the UCA reaches its end factor. It will cause a new Business method to start.

The output of the UCA need to be used to set the beginning values of variables inside the enterprise manner.

There is not any idea of co-relation in begin message occasion because it's miles growing a brand new BPD instance and such there may be no statistics to evaluate it to.
