Hey buddies,

since some months I’m looking for an specialized IBM course on DB2, I already got the diploma of this one, but the thing I want is to get some more knowledge around zOS area, some one like this:

DB2 9 for z/OS Database Administration Workshop Part 1 (ES) (I couldn’t because we were 2 persons subscribed on 4 minimum )

Or this one:

DB2 9 for z/OS System Administration (ES) (I couldn’t because I was the only one subscribed…)

So, as my two database possibilities were gone, I decide to move forward and try over the System Performance line:

Basic z/OS Tuning Using the Workload Manager (WLM) (ES)

And yes! I got it on the third round.
Skills taught:

  • Describe a performance and tuning methodology
  • Develop a systematic z/OS performance and tuning plan
  • Describe the factors which could affect the performance of an z/OS system
  • Use the WLM ISPF application
  • Describe the components of a service definition
  • Define workloads and service levels and classification rules
  • State which z/OS commands affect WLM operation
  • Identify the major WLM services for z/OS, including enclaves and application environments, and how they are used by DB2, WebSphere, and CICS
  • Analyze Central Processing Unit (CPU) performance when running in a shared logical partitioned mode (LPAR) environment
  • Measure and tune z/OS Direct Access Storage Device (DASD), processor storage, and Coupling Facility (CF) configurations
  • Explain the functions and facilities of RMF and System Management Facility (SMF)
  • Analyze performance bottlenecks using RMF
  • Use Workload License Charges (WLC), defined capacity, and soft capping to manage software costs
  • Describe advanced z/OS environments that utilize Intelligent Resource Director (IRD) and Enterprise Workload Manager (EWLM)

Looks cool, I’m looking forward to start it on Monday’s 30th .
