8. Upgrading SQL Server
Sydney Business & Technology 28th July
User Group 2010

9. Upgrade Methodologies
• “Wing it and see” (Hope for the best…)
• More structured approach
– Assess environment
– Determine pre-upgrade tasks
– Determine post-upgrade tasks
– Determine upgrade strategy
– Determine resource requirements

10. Upgrade Strategy
• Major Decision Point
– In-place Upgrade
– Side-by-side Migration
• SQL Server Upgrade Advisor
• Strongly consider going to x64 architecture
• Should have post-upgrade validation strategy
– “Correctness”
– “Performance”

12. Executive Summary
• It’s all about benefits versus risks
• Dependent on your existing SQL Server
infrastructure and how it is managed
• Do not aim for an improvement in
performance because of an upgrade
• Major cost will be in time/effort
• Watch out for technology dependencies

13. Product Support Lifecycle
• “Extended Support includes paid support (support that is charged on an
hourly basis or per incident), security update support at no additional
cost, and paid hotfix support.”
• “To receive hotfix support, an Extended Hotfix Support contract must be
purchased within the first 90 days following the end of the Mainstream
Support phase.”
• “Microsoft will not accept requests for warranty support, design changes,

must purchase a new full license for the SQL Server 2008 R2
edition you want.”
– “Each Server License for SQL Server 2008 R2 Enterprise permits
you to run the software in up to four (4) OSEs (physical and/or

32. Complex Event Processing
• Complex Event Processing (CEP) is the continuous and incremental
processing of event streams from multiple sources based on
declarative query and pattern specifications with near-zero latency.
Database Applications Event-driven Applications
Query Paradigm Ad-hoc queries or requests Continuous standing queries
Latency Seconds, hours, days Milliseconds or less
Data Rate Hundreds of events/sec Tens of thousands of events/sec or
more
Model
request Event
output
input stream
response stream
Sydney Business & Technology 28th July

33. CEP Use Cases
• Manufacturing • Financial Services
– Sensor on plant floor – Stock & news feeds
– React through device – Algorithmic trading
controllers – Patterns over time
– Aggregated data – Super-low latency
– 10,000 events/sec – 100,000 events /sec
• Web Analytics • Utilities (Power)
– Click-stream data – Energy consumption
– Online customer behaviour – Outages
– Page layout – Smart grids
– 100,000 events /sec – 100,000 events/sec

35. StreamInsight
• Platform from Microsoft for continuous and incremental processing
of event streams from multiple sources based on declarative query
and pattern specifications with low latency
Sydney Business & Technology 28th July
User Group 2010

36. CEP Event Streams
• A stream is a possibly infinite sequence of events
– Insertions of new events
– Changes to event durations
– Examples: time series sensor data, log entries
• Stream characteristics:
– Event/data arrival patterns
• Steady rate with end-of-stream indication
Examples: files, tables
• Intermittent, random, or in bursts
Example: retail scanners, web, weather telemetry
– Out of order events
• Order of arrival of events does not match the order of their
application timestamps
• CEP engine does the heavy lifting for you when dealing with out-
of-order data
Sydney Business & Technology 28th July
User Group 2010

37. CEP Query Features
• Operators over streams
– Calculations (PROJECT)
– Correlation of streams from different data sources (JOIN)
– Check for absence of activity with a data source (EXISTS)
– Selection of events from streams (FILTER)
– Stream partitioning (GROUP & APPLY)
– Aggregation (SUM, COUNT, …)
– Ranking and heavy hitters (TOP-K)
– Temporal operations: hopping window, sliding window
• Extensibility – to add new domain-specific operators
• Queries are written over specific event types
– They can be evaluated on all data sources with the same event type
• Support for streaming data, reference data (lookup), and historical
data (replay)

different scales
• At the edge – close to the data CEP

39. For the DBA (DBD)
• Backup compression in Standard Edition
• Support for 256 logical processors
• Unicode compression
• SQL Server Utility
• Data-Tier Application
• Live Migration
Sydney Business & Technology 28th July

40. Support for 256 Logical Processors
• Requires Datacenter Edition
• Default MAXDOP = 64
• New Paradigm
– CPU Groups
• Internal locking structures had to be re-
written
– Can still get lock-hash key collisions!
Sydney Business & Technology 28th July

41. Support for 256 Logical Processors
Sydney Business & Technology 28th July
User Group 2010

42. Unicode Compression: Problem
• SQL Server Uses UCS-2 encoding
– NCHAR and NVARCHAR data always take 2 bytes
of storage
– 1 byte wasted for most deployed locales
– Existing ROW compression ineffective
– PAGE compression only helps for exact match
• Competition
– Oracle supports UTF-8 encoding
– DB/2 supports UTF-8 and Unicode compression
Sydney Business & Technology 28th July
User Group 2010

43. Unicode Compression: Solution
• Use standard SCSU compression technique
– http://www.unicode.org/reports/tr6/tr6-4.html
• No application change needed
• Compression Achieved
SCSU UTF-8
Locale 0.5 0.5
Japanese .85 1.0
Korean 1.0 1.0
Turkish .52 .53
German .5 .5
Vietnamese 0.61 0.68
Hindi 0.5 1.0
Sydney Business & Technology 28th July
User Group 2010

44. Unicode Compression: Upgrade
• ROW compression enabled in SQL2008
– No database changes when upgraded
– Unicode value compressed only if it saves space. It
happens when:
• An existing value is updated
• A new row is inserted
• Index is rebuilt with ROW or PAGE compression
• PAGE compression enabled in SQL2008
– Same as with ROW compression
• No changes needed to existing scripts and DDL

45. SQL Server Utility
• “Provide administrators
a holistic view of SQL
Server resource health
through an instance of
SQL Server that serves
as a utility control point
(UCP). ”
– SQL Instances
– Data tier applications
– Database files
– Storage volumes
Sydney Business & Technology 28th July
User Group 2010

46. Utility Control Point (UCP)
• UCP provides a consolidated view of resource
health collected from managed instances of SQL
Server in the SQL Server Utility
• Each managed SQL Server instance configuration
and performance data to the UCP every 15
minutes
• Metrics
– CPU utilization
– Database file utilization
– Storage volume utilization
Sydney Business & Technology 28th July
User Group 2010

47. Utility Control Point
• Dashboard
• Identify
consolidation
opportunities
• Drill-down to
detailed views
• Simple UI for
policy
adjustments
Sydney Business & Technology 28th July
User Group 2010

48. UCP Requirements
• UCP / Managed Instances Requirements
– SQL Server 10.50 or higher
– Single Windows domain /domains with two-way
trusts
– Service accounts must have read permission to AD
• Additional UCP Requirements
– Datacenter or Enterprise Edition
– Microsoft recommends hosting UCP on case-
sensitive SQL Server instance

49. Data-Tier Application (DAC)
• The Data-tier Application packages database schema with
deployment requirements
• A Data-tier Application package (DACPAC) can be created
in Visual Studio 2010
– Can be extracted from existing applications
– Can define policies
• This integration enables a single unit of deployment for
DBAs to deploy database applications to available servers
that meet deployment criteria.
– Helps significantly streamline deployments, moves and
upgrades by reducing the amount of trial and error associated
with typical database application deployments
• Can be deployed to SQL Server 2008 R2 or SQL Azure

51. DAC Limitations
• Not all database objects are supported
– CLR objects
– Service Broker
– Partitioning
– Security
• Smells a lot like SQL Azure to me…
• Upgrading DACPAC is a side-by-side process

56. Business Benefits
• SQL Server 2008 R2 is a BI release
• Business benefits dependent on how quickly you
can leverage new functionality
– PowerPivot
– Rest of new features predominantly effect operational
/ infrastructure costs
• Cost of upgrade versus new installation
• Watch out for “hidden” costs
• Recommend you spend time/effort to “get your
shop in order”
