ITIL Interview Questions and Answers

Introduction.

The Information Technology Infrastructure Library (ITIL) is a set of practices for IT service management (ITSM) that focuses on aligning IT services with the needs of business. In its current form (known as ITIL 2011 edition), ITIL is published in a series of five core volumes, each of which covers an ITSM lifecycle stage. ITIL underpins ISO/IEC 20000 (previously BS15000), the International Service Management Standard for IT service management, although differences between the two frameworks do exist.

SAP BO Tutorial Overview | Online SAP BO

SAP BO

SAP Business Objects is an enterprise software company, specializing in business intelligence. Business Objects was acquired in 2007 by SAP AG a German company. SAP Business Objects software helps organizations gain better insight into their business, improving decision-making and enterprise performance. SAP Business Objects Business Intelligence (BI) platform supports the entire range of end-user reporting, query and analysis, and performance management uses.

Understanding this infrastructure will help you successfully administer SAP Business Objects Business Intelligence (BI) platform.

By understanding Business Intelligence (BI), you will better comprehend how SAP BusinessObjects Business Intelligence (BI) solutions address the BI product spectrum.

Garner Inc., a research and advisory firm that helps clients leverage technology, coined the term “Business Intelligence” in the late 1980s.

Business Intelligence, as defined by Gartner, is an iterative user-centered process that includes accessing and exploring information, analyzing this information, and developing insights and understanding that lead to improved and informed decision making.
BI usage crosses the spectrum of users, both internally and externally throughout any enterprise, and includes rank-and-file workers, executives, analysts, and knowledge workers.

Examples of internal and external BI applications include:

-Generating a class list for a training session

-Creating an employee performance review

-Scheduling in a health care setting

-Manufacturing computer parts

Business Intelligence can help organizations to:

-Identify and track key performance metrics against their direct competitors and the overall market
-Improve customer service and target high yield accounts

-Streamline operations and improve supplier and warehouse operations

-Identify successful marketing campaigns

-Improve response time to market trends and customer requests

-Decrease query and reporting time

-Reduce cost and anxiety over compliance

-Deliver true cost of goods and services

-Reduce strain on IT departments

Business Intelligence provides insights that enable business managers to make tactical decisions, as well as to establish, modify, or tune business strategies and processes in order to gain competitive advantage and improve business operations and profitability.

Expression Transformation in Informatica

Expression transformations are used for row-wise manipulation. For any type of manipulation you wish to perform on an individual record, use an Expression transformation. The Expression transformation accepts the row-wise data, manipulates it, and passes it to the target. The transformation receives the data from the input port and sends the data out from output ports.

This is of type passive transformation which allows you to calculate the expressions for each record. An expression transformation in Informatica supports to write expression either in variable ports or only in output ports. In this Informatica Tutorial for Beginners, we will learn about Expression Transformation, it uses and examples. We will also learn about Rank Index and Rank Transformation in other posts.

Informatica Expression Transformation Uses

Use an Expression Transformation to derive the new attributes to change the inconsistent data into consistent format.

Use Expression Transformations for any row-wise calculation, such as if you want to concatenate the names, get the total salary, and convert it to uppercase

An expression transformation is created with following types of ports.

• Input port (I)
• Output Port (O)
• Variable Port (V)

Variable Ports

A transformation variable is created by creating a port and selecting the V check box. When V is checked, the I and O check boxes are grayed out. This indicates that a variable port is neither an input nor an output port.Variables Ports are not visible in Normal view, only in Edit view.

1) Simplify complex expressions e.g. extract month from a date for use in several output ports
2) Provide temporary storage
3) Improve efficiency
4)Variables are initialized (numeric to 0, string to “”) when the Mapping logic is processed

Ports are evaluated in the order

1) All input ports
2) Variable ports in the display order (expressions can refer to input ports and variable ports that appear earlier in the port list)
3) Output ports (expressions can reference input and variable ports

Advanced Properties for Expression Transformation

Tracing Level Amount of detail that appears in the log for this transformation. You can choose terse, normal, verbose initialization, or verbose data. Default is normal.

Study WebSphere MQ Online

The intent of WebSphereMq tutorials is to provide in depth understanding of WebSphere MQ software. 

What is WebSphere MQ?

This document contains step by step technical information to learn MQ series, by using this one can start working with control and WebSphere MQ script commands through the Windows Explorer and UNIX/AIX Command line interface.

MQSeries runs on a variety of platforms. The MQSeries products enable programs to Communicate with each other across a network of unlike components, such as processors, subsystems, operating systems and communication protocols. MQSeries programs use a consistent application program interface (API) across all platforms.

MQSeries can be configured to provide assured delivery of the messages. Assured delivery means that even if the hardware or software platform crashes the messages within the system will still be delivered, once the platforms are brought back up. On a typical target system MQSeries consists of a queue manager and a number of queues and channels.

Message in MQ

An WebSphere MQ Series message is simply a collection of data sent by one program and intended for another program. The message consists of control information and application specific data. The control information is required in order to route the message between the programs to some extent. A message can be classed as persistent or non- persistent. A persistent message will survive a software or hardware crash / reboot, once communicated to a queue manager, whereas a non-persistent message will not survive. Persistent messages are used as part of the implementation of the assured delivery service supported by MQSeries.

MQ Queue Manager

It is the queue manager that provides the queuing services to the application programs. A queue manager in MQ Series also provides additional functions so that administrators can create new queues, alter the properties of existing queues and control the operation of the queue manager. Many applications can make use of the queue manager’s facilities at the same time, and they can be completely unrelated. It is possible to connect queue managers on different platforms together, this is achieved via a mechanism called channels.

Websphere Message Queues

Queues are named message repositories upon which messages accumulate until they are retrieved by programs that service those queues. WebSphere MQ Queues reside in, and are managed by, a queue manager. Programs access queues via the services provided by the queue manager. They can open a queue, put messages on it, get messages from it, and close the queue. It is also possible to programmatically set, and inquire about, the attributes of queues. Queues are either defined as local or remote. Local queues allow programs to both put messages on, and get messages off, while remote queues only allow programs to put messages on. Remote queues are used in order to provide put access to queues that are local to another platform. Any message put onto a remote queue is automatically routed to the associated platform and local queue by the queue manager via the channels mechanism.

Channels

Channels are named links between platforms across which messages are transmitted. On the source platform the channel would be defined as a sender and on the destination platform as a receiver. It is the sender channel definition that contains the connectivity information, such as the destination platform’s name or IP address. MQ Series Channels must have the same name on both the source and destination platform.
