Degradation

We get so we are accustomed to some level of performance with our 400, then unexpectedly it is like someone has put on the brakes. Whoah, how come it is so sluggish right now? Here are links to tips and techniques what you can do when this happens, to figure out what is going on, and fix it.

These tips can also help when you experience what might be called a slide into oblivion, in which the 400 seems to slowly but steadily appear to be running more slowly. What the heck is going on, and how do we fix it?

• SYSCMDUSNO = one of the CLP/400 examples. This CLP/400 program lists bad stuff that's recently been going on, such as:
  • CPF4058 = Here's a file with significant growth, better do something before it explodes.
  • CPI1479 = Your 400 has become over-taxed with interactive activity. Your choices include:
    • Grin and Bear it
    • Bare your company wallet to IBM
    • Analyse interactive tasks to see if any can be moved to JOBQ (my first choice)
    • Do something that can get you in big trouble with IBM
    • Downsize the company
    • Update your resume
• WHO BAD = CLP/400 program to display what jobs are using 3 % of system resources or more. You can customize where you do your cut-off.
