– Is it still being used?

• Who’s using it?

• What client applications?

– Was it developed in-house?

• Who is the owner?

– Who are the developers?

» Is it documented?

» What are the external-dependencies?

» What are the cross-database dependencies?

– Does the vendor support an upgrade?


28th July 2010

So… You’re Here Because You’re…

• Installing a new instance of SQL Server

• Upgrading existing SQL Server instance

• Interested in the Visual Studio 2010 session


28th July 2010

Upgrading SQL Server


28th July 2010

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


28th July 2010

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”


28th July 2010

Agenda

• Executive Summary

• Licensing

• New Features

• Changes For DBAs


28th July 2010

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


28th July 2010

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, or new features during the Extended Support phase.”

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


28th July 2010

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


28th July 2010

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)


28th July 2010

CEP Deployment Alternatives

• Event processing engines are deployed at multiple places on different scales

• At the edge – close to the data source

• In the mid-tier – consolidate related data sources,

• In the data center – historical archive, mining, large scale correlation.

For the DBA (DBD)

• Backup compression in Standard Edition

• Support for 256 logical processors

• Unicode compression

• SQL Server Utility

• Data-Tier Application

• Live Migration


28th July 2010

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!


28th July 2010

Support for 256 Logical Processors


28th July 2010

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


28th July 2010

Unicode Compression: Solution

• Use standard SCSU compression technique – http://www.unicode.org/reports/tr6/tr6-4.html

• No application change needed • Compression Achieved


28th July 2010

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

http://www.unicode.org/reports/tr6/tr6-4.html





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


28th July 2010

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


28th July 2010

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


28th July 2010

Utility Control Point

• Dashboard

• Identify consolidation opportunities

• Drill-down to detailed views

• Simple UI for policy adjustments


28th July 2010

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


28th July 2010

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


28th July 2010

Data-Tier Application (DAC)


28th July 2010

Management Studio

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

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”
