This course offers a comprehensive introduction to IMS for all those new to the IMS environment. It provides ideal cross-training for application support specialists from disciplines such as CICS, COBOL, JAVA, or DB2. The course introduces and explains all areas of IMS databases in both the Batch and Online environments, including data access using the DL/I Language Interface and the maintenance of data integrity using the DBRC feature. Written exercises reinforce the formal tuition sessions. These include the analysis of sample applications and use of the procedures and utilities required to recover from various application and system failures.

A general understanding of the IBM enterprise server (mainframe) computing environment and an appreciation of application development concepts is assumed.

describe the architecture of IMS batch and online systems
analyse database and communication calls
identify appropriate logical and physical database design features
describe the structure of secondary indexes and logical relationships
use IMS utilities to backup, restore, and reorganize the database
discuss the facilities available in IMS to provide data integrity and system availability.
trace the flow of a transaction through an IMS system

IMS Essentials Training Course in Norway

The Nordic country Norway, is in Northern Europe. Known for its stunning natural beauty, including fjords, mountains, and forests, Norway is also famous for its high standard of living and strong social welfare system. Norway's capital and largest city is Oslo. Tromsø, Bergen, Trondheim and Stavanger are the other tourist attracting cities of Norway.

Norway is a constitutional monarchy with King Harald V as the head of state. The country has a population of 5,425,270 as of January 2022. Norway is a relatively small country and has a relatively low population density, with much of its land area covered by forests, mountains, and fjords. Despite its small size, Norway is known for its rich cultural heritage, strong economy, and stunning natural beauty, which attracts millions of visitors every year. This Nordic country is also known for its winter sports, such as skiing and snowboarding, and is a popular destination for outdoor enthusiasts.

Norway has a long history of invention and is home to numerous more top-tier tech firms and research facilities, such as; Kongsberg Gruppen, Telenor, Atea, Evry and Gjensidige Forsikring.

Due to the country's high latitude, there are large seasonal variations in daylight. From late May to late July, the sun never completely descends beneath the horizon. Which attracts many tourists around the world to see the "Land of the Midnight Sun". Tourists mainly visit Sognefjord, Norway's Largest Fjord, Pulpit Rock, one of the most photographed sites in Norway and of course the capital; Oslo.

Oslo is considered the business center of Norway. It is the country's largest city and the capital of Norway. The city is home to many of Norway's largest and most important companies, as well as several international organizations and research institutions. Additionally, the city is a popular tourist destination, known for its scenic location on the Oslo Fjord, its many museums and cultural attractions, and its vibrant nightlife and dining scene. Some of the most popular museums in Oslo are The Norwegian Museum of Cultural History, The Nobel Peace Center, The National Museum of Art, Architecture, and Design, The Munch Museum and The Vigeland Museum.
