DATES:

HANDS-ON TRAINING:
    1. Definition of Performance
      • The components and types of VSAM datasets.
      • Identify the performance areas that need to be managed.
    2. KSDS Structure
      • The concepts of splits, where to find splits statistics, and what to do with splits.
      • Create a KSDS and load it with data.
      • Code a program which will cause splits.
      • Determine the number of CA and CI splits and undertake the effort to improve its implementation on the existing program.
    3. Tuning at the AMS Define Cluster Level
      • Examine VSAM usage at the client installation and how it can be improved.
      • Given case studies with usage statistics, provide estimates on storage, I/O amounts, and memory.
    4. AMS Define Cluster
      • Recognize the difference between allocating a VSAM dataset for CICS and batch.
      • Create a VSAM KSDS for online processing.
    5. Complex Datasets
      • Minimize the number of splits on a KSDS.
      • Create a KSDS with distributed freespace.
    6. Performance Programming
      • Determine when a dataset should be reorganized.
      • Given system statistics from a LISTCAT, calculate the VSAM ratios and determine whether a dataset should be reorganized.
