JNDI (Java Naming and Directory Interface) Interview Questions
Question 24. What Is Gateway? Or How Do You Converge Or Diverge The Process Flows? What Are Different Gateways Available And When Do You Use Each?

Answer :

Gateways manipulate the divergence and convergence of a series float, determining branching and merging of the trails that a runtime technique can take.

You can version the subsequent forms of gateways on your manner diagram:

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

Use a parallel, converging gateway whilst you need to converge all available paths.

Inclusive (OR): Use inclusive, diverging gateway while you need to comply with one or extra to be had paths based on conditions which you specify.

Use downstream of an inclusive diverging gateway to converge more than one paths right into a unmarried course after all of the lively paths completed their runtime execution. The inclusive be part of seems upstream at every course to decide whether or not the direction is energetic, wherein case it waits. Otherwise, it passes the token via with out waiting.

Note: Inclusive gateways can observe a most of n–1 paths. So, in case you version a conditional cut up with three paths, the technique can observe two of these paths

Exclusive (XOR): Use to model a factor inside the system execution in which best certainly one of several paths may be observed, depending on a situation, or to model a factor in system execution while the token for one among numerous incoming paths is exceeded thru the gateway.

Event: Use to version a factor within the procedure execution in which best one in all several paths may be observed, depending on occasions that arise. A precise event, which include the receipt of a message or timer occasion, determines the direction to be taken. An occasion gateway ought to be modeled a positive way as described in Modeling event gateways.

Be privy to the subsequent when using gateways:

After you drag a gateway from the palette on your method diagram, you could select any of the available gateway sorts.

When you version inclusive and one of a kind gateways, if all situations compare to false, the manner follows the default collection waft. The default collection flow is the first collection drift which you create from the gateway to a following pastime, but you may exchange the default collection glide at any time.

J2EE Interview Questions
Question 25. What Are Different Task Types?

Answer :

User Task:

User tasks must be completed by means of process individuals and are associated with Human offerings through default.

For cases wherein you need a person to begin the service but no additional consumer involvement is needed, you may also choose a user venture kind and partner a carrier with it, which include an Integration or Advanced Integration service.

Process Designer automatically creates the desired user implementation that you want while you drag procedure components onto a diagram. You also can pick out User Task and an related provider for an hobby implementation, as defined in Implementing sports.

System Task:

System tasks have to be finished via an automated system or provider and are automatically run without a want for user initiation no matter the sort of lane in which they're described in a BPD diagram.

When you drag an Ajax carrier, General System carrier, Integration carrier, or Advanced Integration carrier from the library to a BPD diagram, Process Designer mechanically creates an hobby with a System challenge type, no matter whether the service is dragged to a system lane or to a player lane.

Dragging an pastime from the palette to a device lane in a BPD diagram automatically creates an activity with a System challenge with the Default System carrier decided on. System tasks that you region in a non-gadget lane also are run via the system.

Decision Task:

Decision responsibilities are useful whilst you want a choice or circumstance in a business rule to determine which procedure implementation is started out.

When you drag a Decision provider from the library to a BPD diagram, Process Designer mechanically creates an pastime with a Decision undertaking.

Question 26. What Is Sub-system?

Answer :

A subprocess represents a set of logically related steps contained inside a determine method. You can view a subprocess as a unmarried hobby, providing a simplified, high-level view of the figure manner, or you could drill into the subprocess for a more distinctive view of its contents.

Subprocesses can include swimlanes which can be distinct from the determine process. For example, activities in your subprocess can be finished by a hard and fast of members that is one-of-a-kind from the set of individuals that perform the activities in the determine technique.

Like different sports, subprocesses can be configured to run multiple times in the execution of the parent method by means of configuring looping conduct at the subprocess hobby element inside the parent technique.

Tibco Admin Interview Questions
Question 27. What Are Different The Sub Process Types?

Answer :

There are 3 forms of subprocesses that you may model in a BPD. Their traits are defined within the following table.

Subprocess:

A non-reusable subprocess that exists best within the parent system

Characteristics:

Each subprocess have to comprise as a minimum one start event with an implementation kind of None.

Activity names need to be precise with admire to the pinnacle-stage technique sports, and all different subprocesses and occasion subprocesses underneath the same pinnacle-stage procedure.

Variable Scope:

Inherits variables from the parent procedure and might contain nearby private variables seen most effective within the subprocess.

Variable names declared in a subprocess cannot be similar to variable names declared in any of its discern procedures. If there are more than one layers of embedding, with subprocesses contained within different subprocesses, variable names have to be particular all through the complete subprocess hierarchy.

Linked process:

A call to some other reusable procedure.

Characteristics:

The technique referred to as with the aid of the connected procedure activity can contain more than one start occasions, however must include at least one begin event with an implementation form of None.

Variable Scope:

Variable data is nearby to every system, therefore statistics mapping is required to pass facts into and out of the linked process.

Event subprocess:

A specialised form of non-reusable subprocess that isn't a part of the ordinary series go with the flow of its parent technique, and which would possibly arise 0 or usually all through the execution of the figure technique.

Characteristics

 

Must include a single begin event, which can be one of:

Timer

Message

Error

Event subprocess execution can interrupt parent technique or can run in parallel.

Activity names must be unique with appreciate to the pinnacle-stage system activities, and all different subprocesses and event subprocesses below the same top-level method.

Boundary events are not supported on an occasion subprocess.

Variable Scope:

Inherits variables from the discern process and might incorporate local private variables visible handiest inside the subprocess.

Variable names declared in an event subprocess can't be the same as variable names declared in any of its parent processes. If there are multiple layers of embedding, with occasion subprocesses contained inside different subprocesses, variable names ought to be specific in the course of the complete subprocess hierarchy.

Core Java Interview Questions
Question 28. How Do You Assign The Activities To Users?

Answer :

For any activity with a BPM provider implementation, you may designate the customers who receive the runtime project by way of using the Assignments page within the residences for that interest.

In the Designer view, click on an hobby in a BPD diagram to display its houses.

Go to the Assignments page in the residences view.

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

Last User in Lane:

Assigns the runtime venture to the user who finished the activity that at once precedes the chosen interest inside the swimlane.

Do not select this selection for the first hobby in a lane unless the pastime is a carrier in a pinnacle-level BPD and a Start Event is in the lane. In this example, the runtime challenge is routed to the person who started the BPD.

Lane Participant:

Assigns the runtime challenge to the player group related to the swimlane wherein the selected interest is placed (the default choice).

Routing Policy:

Assigns the runtime mission in keeping with the coverage that you set up.

List of Users:

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

Custom:

Assigns the runtime task in line with the JavaScript expression which you provide in the corresponding area. To select one or more variables to your expression, click the variable choice icon subsequent to the sector.

The JavaScript expression produces outcomes such as USER:<user_name>, ROLE:<group_name>, or PG:<participant_group>, wherein user_name is the name of an IBM® BPM person (inclusive of tw_author), group_name is the name of an IBM BPM security group (along with tw_authors), and participant_group is the call of a group of users on your organization.

Question 29. What Are Coaches?

Answer :

Coaches are the user interfaces for human offerings.

There are  forms of user interfaces for human services: dashboards and mission crowning glory. To build both kind of user interface for human offerings, you operate Coaches.

When a Coach is a dashboard user interface, customers can run it as a stand-by myself consumer interface at any time. The customers access it thru the Process Portal.

When a Coach is a mission of entirety user interface, it is a part of the human carrier waft. At run time, whilst the drift enters the Coach, the user sees the person interface that is described for that Coach. The person interface includes HTML code this is displayed in an internet browser. The go with the flow leaves the Coach whilst a boundary occasion happens. A Coach can have multiple go out flows with every one related to a extraordinary boundary event.

Agile Methodology Interview Questions
Question 30. Explain The Difference Between The Coaches And Coach Views.?

Answer :

Coaches contain one or more Coach Views. The Coach Views offer the person interface elements and format for the Coach.
Each Coach View can comprise one or more different Coach Views, which creates a discern-baby courting between those Coach Views.
At run time, the determine Coach View is rendered as a <div></div> tag that consists of a nested <div></div> tag for every toddler Coach View.
Each Coach View can also have a binding to a business object, CSS code to manipulate its visible layout, and JavaScript to outline its behavior
Coach Views are reusable so you can create a library of commonplace consumer interfaces and behavior. You can integrate these common person interfaces to unexpectedly broaden new Coaches.
The Coaches toolkit that is included with IBM BPM carries a hard and fast of not unusual user interfaces which might be known as inventory controls. You can consist of those inventory controls whilst you are creating your own Coach Views.
Question 31. What Are Differences Between Coaches And Heritage Coaches?

Answer :

1. Coaches can include multiple Coach Views. Coach Views are reusable collection of person interfaces and can be certain to a statistics kind. They can be shared between the Coaches. But in Heritage Coaches, all UI factors want to be recreated.

2. Coaches have web 2.Zero look and behavior and  have client side information version i.E. Records can be refreshed with out the whole web page refresh. They use Dojo 1.7.Three.

Three. Instead of the one-button mechanism of Heritage Coaches, Coach Views use named boundary events. Programmers use boundary events for actions together with information updates with the server and transitions to other Coaches or offerings

four. Coaches aid collaboration while Heritage Coaches do no longer. More than one man or woman can work at the same Coach example at the identical time of their own browsers

five. The manipulate ID of a view-based totally Coach is different from the control ID of a Heritage Coach. The manage ID of a Heritage Coach is the div node ID. This is not the case in view-primarily based Coaches because Coach Views are reusable and you could have multiple perspectives in a Coach.

In view-based totally Coaches, the manage ID is the price of the information-viewid attribute of a <div></div> tag. By the use of the facts-viewid attribute, View builders can locate the nested View because statistics-viewid is particular within its parent or enclosing view.

Coach can not contain Heritage Coach elements and Heritage Coaches can not comprise Coach Views. That is, a user interface should be a Coach or Heritage Coach and not a mix of the 2.

Question 32. How Do You Perform Validation On Coach Views?

Answer :

To validate the records this is within the Coach earlier than the flow proceeds to the next step in the service float, add a validation node to the go with the flow. The validation node can be a nested service or a server script. The server script is the less complicated implementation even though the nested service offers more flexibility.

Example server script:

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

if (tw.Local.Software.Call == “”)
tw.Gadget.AddCoachValidationError(tw.Nearby.Validate, “tw.Local.Software.Name”,
“The name can't be empty.”);

Question 33. How Do You Enable Javascript Debugging For The Coaches?

Answer :

For debugging functions, you could set your Coaches and Coach Views to use the readable variations of Dojo and the Coach framework JavaScript.
Open the administrative console and click Resources > Resource Environment > Resource Environment Provider
On the Resource environment companies page, click on Mashups_ConfigService.
Under Additional Properties, click Custom houses. The list of custom residences opens.
Click isDebug, change the Value area to true, and then click on OK.
Save your adjustments to the master configuration.
Restart the utility server example.
JDBC Interview Questions
Question 34. How Do You Generate A Unique Id For A Coach View At Runtime?

Answer :

In a few conditions you might want to apply the ID attribute in your DOM factors within a teach view. However, all DOM IDs must be globally unique.

For instance: during collaboration the default highlighting conduct is applied based on a completely unique DOM ID. To ensure a unique ID, you can use the $$viewDOMID$$ placeholder key-word. At run time, this key-word will get replaced through the Coach View DOM ID.

Question 35. How Do You Fire A Boundary Event Pro-grammatically?

Answer :

this.Context.Cause(callback);

Question 36. How Do You Access A Child Coach View?

Answer :

context.GetSubview(viewId, requiredOrder)

Accesses a subview example given the subview ID. This technique is comparable tocontext.Subview[viewid] except that the go back cost is an array of subview instances.

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

requiredOrder (boolean) – (optionally available) suggests whether or not the array back wishes to maintain the equal order as in the DOM tree. The default cost is false.

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

The best difference between the two calls and the function callthis.Context.GetSubview(“viewid”, real) is thatthis.Context.GetSubview(“viewid”, real) returns an array of subview objects whose order matches the order of the DOM nodes inside the DOM tree.

TIBCO Interview Questions
Question 37. What Are Under Cover Agents (uca)?

Answer :

An undercover agent is began through an event. The occasion can be a message occasion, a content material occasion, or a timer event that is the result of a selected time table.

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

When an secret agent executes, it invokes an IBM Business Process Manager provider or a BPD in response to the occasion.

When you encompass a message event or content material event in a BPD, you must connect an spy to the event. For instance, whilst a message occasion is acquired from an external gadget, an undercover agent is wanted to cause the message occasion in the BPD in response to the message.

Question 38. How Do You Enable Uca To Start A Bpd?

Answer :

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

Restart the product, and take a look at the TeamworksConfiguration.Running.Xml document to make certain that the placing has the appropriate value. The assets is ready to fake via default, and if you don’t alternate it, you may have errors that save you the BPD from beginning.

Question 39. What Is Tracking? How Do You Enable It? What Are The Different Ways Of Tracking? What Happens When You Enable Tracking?

Answer :

To create customized and 0.33-party reports in IBM® BPM, you want to discover the data to song and send that records to the Performance Data Warehouse.

To song records in a commercial enterprise technique definition (BPD), use autotracking, tracking businesses, or each.

Autotracking:

automatically captures information from monitoring factors on the access and exit of each item in a BPD (as an instance, offerings, activities, and gateways).

To enable autotracking, make sure that Enable Auto Tracking is chosen under the Tracking tab of the Business Process Diagram. (This is the default.)

Tracking agencies:

offer more control over tracked statistics. For instance, use tracking businesses music a selected organization of technique variables throughout multiple BPDs or technique packages and to keep tracking factors for a timing c programming language.

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

Note that the Enable tracking placing does not observe to offerings with tracking points. Tracking facts is constantly enabled while services contain tracking factors.

You can take advantage of both monitoring strategies in a single BPD. If you operate each autotracking and monitoring businesses, you could create a timing interval.

After you configure statistics monitoring on your BPD, and on every occasion you eventually update your information monitoring requirements, you have to send the monitoring definitions to the Business Performance Data Warehouse.

When you send monitoring definitions, both at once or as a part of a picture deployment, the Business Performance Data Warehouse establishes the shape in its database to maintain the statistics this is generated by way of the Process Server when you run instances of your approaches.

In IBM BPM, those tracking requirements are referred to as definitions due to the fact they set up the database schema within the Business Performance Data Warehouse to deal with the tracked statistics generated by the Process Server.

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

Answer :

If you want to investigate the quantity of time that elapses among certain steps for your method, you may upload monitoring factors for your BPD after which create atiming interval to seize the period between defined start and cease points. When you create a timing c language, you could create custom reports that allow you to calculate the period of a system, or examine the duration of numerous procedures.

Do the subsequent duties earlier than creating a timing interval:

Enable autotracking:

Add monitoring points to the commercial enterprise procedure definition

Create a tracking organization to preserve the timing interval facts (make certain to feature every monitoring factor to the monitoring institution you created)

Lombardi Developer Interview Questions
Question forty one. What Are Tracks? How Is It Different From A Versioning System Like Cvs?

Answer :

Process Center tracks the adjustments within the procedure packages the usage of Snapshots.

Snapshots:

Record the nation of the items within a technique utility or song at a specific point in time.

From the Process Center console, you may create snapshots of your procedure packages.

You also can deploy particular snapshots of your manner packages at the Process Servers in staging, check, and manufacturing environments.

Tracks:

Optional subdivisions in a manner utility primarily based on crew obligations or method software versions.
You can decide if additional tracks are necessary for each process software and, if so, enable them at any time
Typically Tracks will be made from manufacturing photo for preservation purposes.
Difference from versioning systems like CVS.
Unlike typical versioning structures, tracks or snapshots cannot be merged in later factor of time. So, It might be difficult for parallel development.
