We’ve all experienced this…

Slow Performance = lost revenue

Efficient use of the Mainframe?
There are mainframe costs too…
• Are we using too many MIPS?
• Does that payment transaction call the
mainframe too many times?
• Do we need to perform that expensive
upgrade to support the new release of
the website or that key internal app?

Application Performance is a Business Issue
Improving performance lowers cost and increases revenue

• Effort to identify and
resolve problems by 83%
• Conversion rate by 74% when
• Calls to call center by
61%
• Abandonment rate by 39%

Top APM Challenges?
13
1
Applications are becoming more
Complex everyday
2
Difficult to Innovate fast enough to
stay ahead of the competition
3
Can't identify and prioritize
performance problems that have the
greatest Business Impact

Difficult to Innovate Fast Enough to Stay Ahead of the
Competition

Issues:
• Business demands are increasing
Test/QA
• Applications are changing
rapidly
• Too many dev/test iterations
• Too long to deliver and repair
• Different tools in dev, QA and prod

Adding the
complexities of the
Mainframe
19
The New Normal of Mainframe
Applications: Customer-facing
Transactions: Increasing
Maintaining Applications: Complexity
Resources: Transitioning
Not addressing these Mainframe Challenges
will drive IT costs up and customer quality down!

Two separate worlds:
The Distributed World
21
The Mainframe
Complexity in the Mainframe
MIPs Utilization
Visibility Gap
Controlling Mainframe Costs
Distributed-Mainframe Disconnect
Blindspots
22
No True End to End Visibility
Fingerpointing
Distributed and Mainframe Worlds
The KEY challenges TODAY:
• No transactional view on
performance:
• Do I have any issues?
• What’s the business impact?
• What’s the transaction?
• Where is the problem?
• Is the issue in the distributed
world or on the Mainframe?
• Who needs to fix it?
23
• MIPS Optimisation:
• How many times does that
payment transaction call the
Mainframe?
• Do we need more capacity on the
Mainframe?
• Can we save MIPS by optimising
the calls and the CICS programs?

What’s KEY to APM in this complex
