  1. Eliminate the Confusion Eliminate the Confusion!

  2. Squeezing Bowling Ball down Garden Hose Optimize & Reduce Workload!

  3. Different Approach Different Approach…

  4. Interactive Response Time 69% - Interactive response time is usually OK, but random slowdowns occur. Can’t find cause – solution appears to be a $100,000 interactive feature card.

  5. Daily GANTT Chart - Interactive

  6. CPU (seconds) by Subsystem

  7. Number of I/Os by Subsystem

  8. Skipped Records by Job/User

  9. Skipped Records by File/Fields

  10. Long Running Batch Jobs 57% - CPU used less than 50%, but batch jobs take a long time & don’t use CPU efficiently. Have been told that a bigger system with more CPU is needed.

  11. Daily GANTT Chart – Long Batch

  12. Temporary Disk Space Jumps 48% - Disk space jumps from 70 to 90%, could be from temp space used by jobs but have not been able to prove which job is doing it.

  13. Disk Navigator – Size of QTEMP by Job

  14. Long Nightly Processing 44% - Night processing runs long, one CL program calls 100s of other programs and it takes 6 hrs to run.

  15. Job Overview – One Process

  16. Job Overview – Several Processes

  17. Application Analyzer – By Program Function

  18. Application Analyzer – By OS/400 Function

  19. Application Analyzer – Open/Close

  20. Java & JDBC Killing System 43% - New web app uses Java & JDBC, when web lookup pages are hit, user waits 2 minutes. System was fine until new app went live.

  21. QUSRWRK CPU Seconds

  22. QUSRWRK Skipped Records

  23. Waiting for Pick Slips 43% - Overall CPU is only 30% used, yet users wait 6 minutes for pick slips to print. When batched, it takes 45 minutes to start printing, which delays product shipping.

  24. CPU 30% Used, Jobs in Queue

  25. # of Jobs by Job and User

  26. Jobs Waiting in Job Queues

  27. Waiting 250 Minutes, Runs 1 Second

  28. Job Logs Wasting Resources 40% - 500,000 pages of job logs generated every day, logs rarely used, wasting disk space, CPU & I/O.

  29. # of Pages by Queue, Job & User

  30. Job Description & End Code

  31. Message Logging

  32. Job Runs 30,000 Times 38% - Our batch job runs 30,000 times per day, consumes 1 CPU second each time it runs. Ends up being 30% of CPU consumed, constantly spikes system all day.

  33. CPU by Job Name

  34. # Jobs by Job Name

  35. HA Can’t Keep Up 30% - Journal receivers are 10 GB per day, HA can’t keep up.

  36. Journal Analyzer
