93). How to convert WSDL (Web Services Descriptive Language) to target language?

94) What is Software component?

Ans) Software components represent the reusable modules of a product

95) What is Software Component version?

Ans) represents a particular version of a software component.

96) What is product?

Product: A software product is composed of one or more software components.

It represents a collection of all versions of a product. A product is a unit that

can be delivered, is visible to the customer, and that is installable and renewable.



97) What are the stacks available in XI?

Ans) 1) Java stack 2) ABAP Stack

98) IDOC and Plain HTTP adapter is it required Sender Communication channel,

Ans) No

98) What is the use of Exactly Once In Order (EOIO)?

Ans) Messages are delivered with the same queue names (supplied by the application) in the same sequence that they were sent from the sender system.

99) When would you use ABAP and Java mapping? What are advantages and disvantages of one vs. the other? Any guidelines on this?

Ans) Java mapping runs on J2EE engine, ABAP Mapping runs on ABAP Stack.I guess ABAP mapping makes more sense if you have a requirement wherein you need to perform multiple RFC classes for RFC Lookup's etc as you can do this very easily Using your ABAP Code. Java Mapping provides a easier means to use Java API's etc and it uses SAX parser which provides better performance while ABAP Mapping uses DOM Parser (I am not very sure on this though) which can cause a performance bottleneck.

Ans) a) Conversions b) Boolean c) Node Functions d) constant e) date

f) Text g) static h) arithmetic



111) BPM Steps?

Ans) Send step:To send a message asynchronously from within an integration process, you use a send step in Asynchronous mode. When a message is sent asynchronously, the send step does not wait for a reply message from the receiver after the message is sent. However, you can specify that the send step must wait for a confirmation of receipt from the receiver, in the form of an acknowledgment.

Container:

You use a container operation to set a value for a target container element at runtime The target container element and the assigned value must have the same data type. To specify the value, use the expression editor.

Receive:

An integration process is always started when a message is received. To receive the triggering message, use the receive step and set the Start Process indicator.

Loop:

You use a loop to repeat the execution of steps within the loop. The loop continues to run while the end condition returns true (while loop).



Fork Step:

You use a fork when you want to continue a process in branches that are independent of each other, for example, to communicate with two systems that are independent of each other. The branches of the fork join in a union operator.

You can specify the required number of branches and then define whether the process must run through all branches, or just a particular number of branches. Furthermore, you can define an end condition for the fork

As soon as a branch reaches the union operator at runtime, the system checks the following conditions in the specified order:

? The process has run through the required number of branches

? The specified end condition has returned true

The step is complete as soon as one of the conditions returns true.

Control Step:

You use a control step to do the following:

Terminate the current process

Trigger an exception

Trigger an alert for Alert Management

Wait Step:

You use a wait step to incorporate a delay in a process. Usually, you use a delay to define when the next step in the process is to start. You can define a delay as either a point in time or a period of time. At runtime, the step waits until the specified point in time is reached or the specified period of time has passed. The system then continues the process by proceeding with the next step.



112) What are alerts? Where & how u have to do alerts?

Ans: Alerts are messages, which can be raised in case of failure. Alert Category can be defined in transaction ALRTCATDEF on abap stack. We can assign recipients to every alert category which specifies who will receive alert in case of error.

Alert rules can be defined in RWB.

113) What are the advantages of SAP XI over other tools?

Ans) XI is a middleware like many others. It is well suited for connecting SAP systems with each other and with non-SAP.If your focus is not on SAP systems, other solutions might be a better choice today. SAP XI provides an integrated workflow engine that allows to define adapters to non-XML-protocols and mappings to convert data content from source to target.

Any fully mature middleware should provide these three layers.

1. An independent Message Queue

2. A data consolidator and mapping engine

3. Workflow processor.

XI is lacking full-fledged Message Queue compared to other established Middleware products. Currently, SAP XI does not have the features like IBM Websphere, Seeburger or TIBCO.SAP's next XI release might provide this missing piece and many more features, which is due 2007 i guess. Here are the advantages of SAP XI from my point of view. There are lots of advantages but to list a few:



* Easy Integration with SAP products & components (RFC, IDOC, Proxy).

* Data security as expected from any SAP product.

* Standards based - XML, XSD, Xpath etc

* Ability to communicate with other messaging systems/products.

* Business Process Management

* Synchronous & Asynchronous communication possible.

* Complex processes for communication possible instead of only sending and receiving (business process management) (connect e.g. asynchronous and synchronous steps, define complex communication scenarios)

* Mapping etc possible to accomplish in Java. Platform independent Java components.

* Java & .Net support.

* Big range of adapters for different technologies / tools (SOAP, Mail, JDBC, CDIX...)available in standard or offered by other companies (EDI e.g. by Seeburger).

* Process functionalities inside XI to modify content in the communication channel on own defined rules for business purposes.

* Central monitoring for data communication for all your communication between different systems.

* And the marketing issue: SAP and its partners provide high volume of development capabilities to make XI always up-to-date for new requirements



114) What is the use of performance monitoring?

Ans) you use performance monitoring to display statistical data on the performance of message processing. The data comes from the Integration Server (IS) or the Process Monitoring Infrastructure (PMI).The central tool for performance monitoring is the Runtime Workbench, which you call from the Integration Builder start page.



115) Message Monitoring?

Ans)

Ø To track the Status of message

Ø To find errors that have occurred and established what cause them.

Ø Display and manage messages

Ø Search for messages using an index

Ø Filter the displayed messages by specific criteria. Configure the message display.



116)what are alerts? Where & how u has to do alerts?

Ans: Alerts are messages, which can be raised in case of failure. Alert Category can be defined in transaction ALRTCATDEF on abap stack. We can assign recipients to every alert category which specifies who will receive alert in case of error.

Alert rules can be defined in RWB.



117) Difference between WebAS java standalone java?

Ans)Web AS Java: Web AS Java systems consist of one or more instances and each instance is installed on a separate host. An instance itself consists of cluster nodes that can communicate with each other.

Standalone Java: Standalone Java technical systems are standalone Java applications that are installed in a computer system from an administration perspective. They can also be installed as an operating system service or as a daemon.
