IMS Database Performance and Tuning (CM30G)

 

Zielgruppe

This intermediate course is for ndividuals interested in the performance of the IMS Database System.

Voraussetzungen

You should complete:

  • IMS Physical Organization of Databases Workshop (U3722)

or have four to six months experience with the IMS database system.

For additional prerequisites visit our Web site and search on U3720.

  • Describe the physical storage and processing characteristics of Hierarchial Indexed Sequential Access Method (HISAM), Hierarchial Indexed Direct Access Method (HIDAM), and Hierarchial Direct Access Method (HDAM) access methods.
  • Code the Data Base Definitions (DBD) and Program Specification Blocks (PSB) macros to implement secondary indexing, HISAM, HIDAM, and HDAM physical databases.
  • Describe the physical storage characteristics of secondary indexes.
  • Describe the PSB and programming requirements and processing characteristics when using a secondary index.
  • Use the IMS utilities to load and reorganize logically related databases with secondary indexes.
  • Use Virtual Storage Access Method (VSAM)s access method services to delete and define the Key-Sequenced Data Set (KSDS) and Entry-Sequenced Data Set (ESDS) data sets needed to support the database environment.
  • Use reports created by the database tools program, DBD/PSB/ACB MapperSpecify buffers for VSAM data set supported databases

Kursinhalt

Learn how to tune Information Management System (IMS) databases for use in IMS/Batch, IMS/Data Communications (DC), CICS-Local-Data Language One (DL/I), and Data Base Control (DBCTL) environments.

Explore the IMS database features that affect performance such as data set considerations and buffers for VSAM and OSAM. You will also practice a method for estimating performance before implementation. Plus, you will reinforce the skills you have learned with seven machine labs.
