OverviewLearn how to successfully implement and tune Information Management System (IMS) databases with IMS logical relationships. Examine in detail the various pointer options. Practice these skills in intensive machine-lab exercises.AudiencePeople responsible for designing, implementing, maintaining, or tuning IMS databases using logical relationships.PrerequisitesYou should have at least four months of experience using IMS and should be able to:
  • • Use TSO/ISPF or PDF
  • • Demonstrate basic knowledge of:
    • OS/VS Job Control Language
    • VSAM access methods service utilities
    • DL/I application programming techniques
  • Describe the characteristics and storage format of HISAM, HIDAM and HDAM databases and code their DBDs
  • Understand the IMS DB Monitor and use its reports to resolve database performance concerns
These skills can be developed by attending:
  • IMS Physical Organization of Databases Workshop (CM22)
  • IMS Database Performance and Tuning Workshop (CM30)
Objective
  • Code the DBDs and PSBs for databases involved in logical relationships, including those using recursive data structures
  • Use IMS utilities to load and reorganize logically related databases
  • Choose logical relationship update rules based upon application processing requirements
  • Identify DBD coding parameters that are critical to the performance of logically related databases
  • Interpret the results of logical relationship implementation choices using the reports provided by the IMS Monitor
Course Outline
  • Introduction to Logical Relationships
  • Unidirectional Logical Relationships
  • Unidirectional Logical Data Structures
  • Bidirectional Logical Relationships
  • Bidirectional Logical Data Structures
  • Database Load and Reorganization
  • Recursive Structures
  • ISRT Rules and Exercise
  • Logical Relationship Performance
  • Logical Relationship Tuning
  • Design and Change Considerations
