The Adabas - Essentials training course covers the major features of ADABAS datasets and their interaction while emphasizing those features which directly affect database performance.

In Adabas - Performance and Tuning training course, you will learn to improve overall performance by taking advantage of Adabas features, analyzing key performance factors and using Adabas monitoring tools. From this information you will understand what guidelines to develop for better performance of the database environment.

By attending Adabas - Essentials workshop, delegates will learn to:

  • Identify the major structures of ADABAS
  • Explain the organization of data within the database, including compression, null suppression and ISN
  • Identify the major access paths to data including indexes, inverted lists and ADABAS’s address converter
  • Identify the major components of the interface between application programs and ADABAS control blocks and use of calling buffers
  • Evaluate the overhead for major commands accessing and modifying the database
  • Identify the components of the nucleus which directly affect its performance and that of database programs

By attending Adabas - Internals workshop, delegates will learn to:

  • Describe in-depth the structure and function of Adabas components
  • Show how each Direct Call operates and explain its impact on Adabas performance
  • Troubleshoot and debug complex Adabas issues

By attending Adabas - Performance and Tuning workshop, delegates will learn to:

  • Use a variety of tool and techniques that enhance and maintain Adabas database performance
  • Interpret Adabas command logs to find performance problems
