3. Understanding the
Problem: The Snowball
Effect
The Harsh Truth
o Creating a well-balanced, well-configured system is not enough
o ALL performance issues must be discovered, identified, and fixed
ASAP
Modern environments are complex, and
interdependent
○ All workloads share and occupy
system resources
○ Transactions depend on each other
to execute properly
One small problem can create multiple big problems.
○ On inefficient transaction occupies too many
resources...
○ Other transactions are delayed until those
resources are free...
○ Workloads are not executed, leading to
systemic failures

Conventional Solutions

6. What Happens When Conventional
Solutions Fail
When conventional solutions encounter an issue they can’t solve, you might:
● See the performance problem, but fail to recognize its root cause
● Recognize its root cause, but have no idea how to solve it
● Know how to solve it, but lack the technical skills to apply the fix
● Apply the fix, but fail to actually generate performance improvement

7. Ultimately, conventional solutions are useful, but insufficient. They:
• Cannot discover, identify, or fix all performance issues
• Require multiple tools and dedicated technical support teams
• Create a flood of alerts— many of which are false positives
• Create a flood of alerts— many of which are false positives

_7 What You Will Get

10. ● Even after creating stable operations, we still did a
lot of firefighting
● Eventually, we developed a way to proactively
solve performance issues
● We developed our approach in the field, working with mainframe clients
● Our teams implement, configure, and maintain their systems and workloads
● I joined the team to act as Db2 system programmer

_9 Our New Solution: Overview

12. What This Does:
● Establishes a baseline of performance data for
evaluations
● Detects the development of bottlenecks and
performance deficiencies
● Evaluates the effects of tuning activities (Did
they work or not)
Done by:
● Collecting and storing long-term performance
data
● Collecting and storing performance data before
and after tuning activities
_10 Our New Solution: Overview

13. Our Basis for Performance and Security Reports:
● System Management Facilities (SMF) records
● Performance Monitor Resource Measurement
Facility (RMF) reports
Tools:
● IBM Omegamon for z/OS
■ The performance and availability of
individual z/OS systems
■ The workload performance and resource
utilization of relevant Parallel Sysplexes
● IBA APPULSE for z/OS
