Abstract
Are you struggling to manage DB2 database
performance supporting mission critical business
applications?
Learn how you can use CA Performance Analytics
for your DB2® for z/OS ® to deliver early warning
system to avoid disaster and maximize your
application performance running on DB2.

Q&A4

How do I deliver a flawless experience every
time an application touches the mainframe?
In the application economy it’s all about your customers.
You need to think about your mainframe reframed.

mainframe applications
Create mainframe
infrastructure flexibility

data on the mainframe

INCREASING
COMPLEXITY
REACTIVE TO
PROACTIVE
EARLY WARNING
Companies are developing
complex SQL applications
on DB2. Performance often
degrades over time
without anyone noticing
(the creeping trend).
An intelligent system that
can recognize and prioritize
significant changes in SQL
performance before it starts to
impact resource overheads
and service level agreements
A DBA often does not
recognize degradation until
customers complain or
service level agreements
have been missed.
The Situation
Ever increasing application volumes and complexity

The Challenge
DBAs struggle to identify, tune & minimize elapsed time, CPU, and Getpages
Methods Adjusts SQL statements, runs reorg utility, tunes databases, etc.
Challenge Finding best applications to tune
Data Performance metrics for executions of SQL statements, packages, and
plans (Version 1 uses data from CA Detector® for DB2 for z/OS)
Limitations Performance metrics tell you where you are, but fall short:
• How you got here (is today’s behavior “normal”?)
• Where you are going (is performance getting better or worse?)
• Where the greatest tuning potential is (which applications account for
the greatest increases in resource usage ? )
• Does is matter if a transaction is using 15 GETP as opposed to 10 one
month ago ? Maybe – what if it executes 20M times/daily, and can you
“normalize dynamic statements ?

A Better Outcome
Proactively monitor application performance or rely on user complaints
 Monitor trends, identify potential problems
before they occur
 Manually determine, set and adjust thresholds
for monitoring applications
 Automatically determine what is “normal”
 Less time needed:
– Reviewing false or short-term “spike” alerts / event
notifications (as opposed to sustained deviations)
– defining /maintaining thresholds

 How do you determine when performance started to degrade?
 How long does it take to identify the problematic SQL statements?
 Do you know how the statements executed before the performance
degraded?
 Do you have a log of application performance problems and
resolutions?
– Can you compare this log with current problems?
 Many customers offload CA Detector datastore into DB2 tables
– Query heaviest plans/packages & manually compare to “baselines”
– No efficient method to re-evaluate baselines when “the world changes”
– How to monitor “standard deviation” and “creeping trend” is complex
and cumbersome
The Challenge
How do you resolve performance problems?

The Solution
CA Performance Analytics for DB2 (Pre-Release)
Rich Visualization,
Dashboards and Alerts

Uses existing CA Detector data to create and maintain baselines for “normal
executions” based on performance metrics:
 DB2 elapsed time, DB2 CPU, Getpages . . . . .
 Metrics kept at the statement level for better diagnostics!!
 Can baseline EVERYTHING
 Can baseline what you believe is important
 When do you need to “re-baseline”
The Solution: Baseline Everything
CA Performance Analytics for DB2

Event notification / Alert management
 Thresholds automatically established when baselines created
 Look for sustained intervals of abnormal activity - generate anomaly alert and
not false alerts for “one-time events”
 Look for trending toward unacceptable behavior
• Generate trending alert
• Trend metrics readily available when alert is generated
 Provide details needed to analyze potential performance issues by illustrating
past, current and future executions based on the trend metrics
The Solution: Automated Alerting

 CA Detector datastore offloaded whenever you decide
 Automatically keeps track of last unloaded data
– Static SQL from plans/packages
– Dynamic SQL “normalized”
– Ships comma-delimited file using secure FTP
 SaaS solution takes care of all the heavy lifting processes
– Baseline calculations
– Append of new data from CA Detector intervals
– Continuously calculating “standard deviation” & “moving average”
– Event creation / notification when applications go off trail
 Why a SaaS solution as opposed to a pure z/OS implementation ?
The Solution: Conserve Storage/MIPS

A SaaS based solution designed to be intelligent and intuitive, with little z/OS overhead.
Benefits of SaaS solution:
 Ships CPU costs off the mainframe
 Affordable
 Quick to Deploy / Reduced Time to Benefit
 Virtually Zero Infrastructure for You to Maintain
 Scalable
 Seamless Upgrades
 Guaranteed Levels of Service
 Backups and Recovery All Done for You
 Works from Anywhere – Web UI
The Solution: Quick Time to Value

Capture
CA Detector collects SQL
interval performance metrics
for analysis.
Creates an historical view of
application performance, which
will be stored in the cloud.
Baseline
Baselines are created that
contain a statistical analysis of
application SQL performance for
a chosen, representative,
period-in-time.
Baseline repository can be
updated when baselines are
determined to no longer be
representative.
Analyze
Analyzes application
performance deviations from
normal execution behavior (i.e.,
deviations from baselines) and
logs in an events repository.
Notify
During the Analyze step,
notifications of performance
deviations can be sent to key
personnel via email.
Review
In addition to output from
Capture, Baseline, and Analyze
the application will allow you to
review application performance
history through a web browser
interface. Deeper analytics and
visualization are available
through the browser dashboard.
