Expectations have changed. That's true for users, executives and customers alike. There's no time for systems running slowly, or cost overruns. That's why fundamentals like capacity planning have become mission-critical. By paying attention to the details, and doing effective forecasts, companies can optimize their information architecture, keeping everyone happy. Register for this episode of Hot Technologies to learn from veteran Analysts Dr. Robin Bloor and Rick Sherman who will offer insights about how and why to do capacity planning. They'll be briefed by Bullett Manale of IDERA, who will explain how his company's SQL Diagnostic Manager can track a wide range of usages metrics which can be used for accurate forecasting.

3. The SQL Story
Robin Bloor Ph.D.

4. A Fundamental Thing
SQL is a Declarative

5. Declarative: The Consequences
u The user does not know or
care about the physical
organization of the data
u The user has no idea
whether the way they
structure the SQL query
will affect performance
u The same is true of the
programmer
u The same is also true of BI
tools. They make no effort
to produce efficient SQL

The Impedance Mismatch
The RDBMS stores data organized
in tables
The OO coder manipulates data
organized in object structures,
with associated methods.
The data does not simply map to
the database table structures so
a mapping is necessary.
Basically: hierarchies, types,
result sets, poor APIs, language
bindings, etc.

p/bottlenecks.jpg
The Impedance Mismatch
SQL has:
DDL (for data definition)
DML (for Select, Project and
Join)
But it has little MML (Math) or
TML (Time)
Usually result sets are brought to
the client for further analytical
manipulation, but this creates
problems
Alternatively doing all analytical
manipulation in the database
creates problems

Database Performance Bottlenecks
CPU: CPU overload, context
switches, I/O waits, CPU cache
Memory: Thrashing,
fragmentation
Disk: Caching, I/O saturation,
fragmentation, SSD performance
Network Overhead
Locking
And poor SQL calls

9. Database Performance Factors
Bad database design
Bad program design
Concurrency, workload
mixing
Load balancing
Query structure
Capacity planning – data
growth

10. In A Few Words
SQL is convenient, but it doesn’t
self-optimize

The Best Laid Plans: Saving Time, Money & Trouble with Optimal Forecasts
Topics
• The Demand
• The Supply (design, develop, deploy & manage)
• The Tools

13. Slide 3 Copyright © 2017 Athena IT Solutions All rights reserved.
The Best Laid Plans: Saving Time, Money & Trouble with Optimal Forecasts
The Need
• The hype is on Big Data & Cloud but…
• Database usage is predominately relational dbms & still growing
• Database market dominated by top vendors
• Two database usage categories:
o Operational Database Management Systems
o Data Warehousing & Data Management Solutions for Analytics

14. Slide 4 Copyright © 2017 Athena IT Solutions All rights reserved.
The Best Laid Plans: Saving Time, Money & Trouble with Optimal Forecasts
The Supply (to design, develop, deploy & manage)
• DBA Shortage
o DBA jobs will increase 11% from 2014-2024
vs 40% annual data growth
o Many DBAs leaving field
• DBA Job
o Managing multiple dbms – volume & variety
o Typically engaged after design
o Overworked & Misunderstood?
o Stressful workloads
o 24x7 responsibilities
• Part-time & “Accidental” DBAs
o IT team small & cannot “afford” a dedicated DBA
o Application developers take on DBA role without
formal training
o Difference between design & development versus
deploy & manage

The Tools – Not Leveraging The Right Tools
• Assume DBMS has sufficient tools
• “Don’t know what you”
• SQL is “go to” tool
• Silo approach

ü Databases versus applications used for

The Tools – Measuring The Right Stuff
• Develop application-centric performance metrics
o Wait-times & bottlenecks
o Data capture, transactions & transformations,
analytics
• Monitor performance
o Databases operations
o Database structures
o SQL
o Applicationworkloads
o Infrastructure environment
• Analyze

§ CAPACITY PLANNING

24. 8© 2016 IDERA, Inc. All rights reserved. Proprietary and confidential.
MAIN REASONS - WHY DO CAPACITY PLANNING?
• Save Money
• Mitigate Risk / Reduce downtime
• Increase productivity
• Increase positive experience of my users
• Make most efficient use of my resources
• Eliminate waste

25. 9© 2016 IDERA, Inc. All rights reserved. Proprietary and confidential.
CAPACITY PLANNING QUESTIONS…
When will I run out of space on the (drive, database, table partition,etc.)?
Which Servers / SQL Instances / Databases / VMs Can I consolidate?
What workloads can I mix on the same instance?
Where and when can I expect my bottlenecks to occur next?
How much should I budget for resource xyz?
What is the most cost effective way to roll out this new application?

HOW SQL DIAGNOSTIC MANAGER CAN HELP

27. 11© 2016 IDERA, Inc. All rights reserved. Proprietary and confidential.
SQL DIAGNOSTIC MANAGER SPACE CONSUMPTION FORECASTING
§ Space Consumption and Forecast Reporting - SQL Diagnostic Manager provides the ability to exploit the
historical data it collects to predict the amount of space consumption required at the table, database and
volume levels for a point in time in the future.

28. 12© 2016 IDERA, Inc. All rights reserved. Proprietary and confidential.
SQL DIAGNOSTIC MANAGER PREDICTIVE
ANALYSIS
§ Predictive Analysis – SQL Diagnostic Manager will evaluate criteria related to the SQL environment that
includes additional inputs than just the level of where a metric falls. For example, SQL Diagnostic Manager
will perform hypothetical index analysis based on the typical workload to identify when indexes should be
added or removed.

29. 13© 2016 IDERA, Inc. All rights reserved. Proprietary and confidential.
SQL DIAGNOSTIC MANAGER BASELINE CONSIDERATIONS
§ Advanced Baselining Capabilities – Baselines can be calculated related to past performance. Additionally multiple
baseline can be set up to provide a better understanding of what is ‘not normal’ taking into consideration the time of
day. For example, production hours vs. maintenance hours.

30. 14© 2016 IDERA, Inc. All rights reserved. Proprietary and confidential.
§ Other Reports and Planning Tools – Comparison reports are provided in a number of areas inside SQL Diagnostic
Manager. These reports are useful when comparing a change after an event has occurred as well as ranking servers
and databases to help with prioritization of addressing issues. These reports are also very useful when performing a
consolidation or moving to another environment like the cloud.
SQL DIAGNOSTIC MANAGER COMPARISON REPORTING

SQL DIAGNOSTIC MANAGER FLEXIBILITY
§ Overall Flexibility – Every environment is different. Out-of-the-box SQL Diagnostic Manager has canned metrics
that are monitored and collected historically for review. The same holds true for reports. Having the ability to extend
this monitoring footprint is paramount, especially for larger enterprise shops. Obscure monitoring requirements will
be necessary. Having a tool that adapts to the environment is crucial.
