About this session

A presentation that was done at the North American Tech-EdDone by Brian Knight

SQL Server MVP, and co-founder of SQLServerCentral.com and JumpstartTV.comwww.PragmaticWorks.com

Written ten SQL Server books

Mapping DTS Knowledge and Skills to SSISRunning DTS Packages in SQL 2005 or 2008Upgrading DTS PackagesUpgrading ActiveX Scripts

Agenda

Why Choose SSIS?

64bit supportParallel in-memory multi buffer architecture helps to load data several times faster than DTSLogging, configuration, CheckPoint etc.Source Safe Integration because everything is XMLMany new tasks (e.g. Script Task, For Each Loop, XML Task etc.) that replace need for ActiveX

DTS vs. SSIS Engine Speed Test

DTSSSIS SQL Server Destination

SSIS OLE DB Destination

Average Runtime (seconds)

33.2 s 11.3 s 12.3 s

On 32 bit dual core machinePulling 1 million rows out and writing to SQL table with no transformationSSIS 65% + faster than DTSAdding transformation would add more SSIS advantagePackage needs to run from the destination server

Project Options

Run DTS in 2005 or 2008Missing the package logsRuns under 32 bit

Upgrade using MS WizardNot compatible with most package

Upgrade using DTS xChangeMinutes per package

Starting from scratchAbout 3-6 hrs per package conservatively

Running Packages Under 2005+

Need to download DTS Designer Components (part of SQL Server 2005 Feature Pack)Pro:

Delays the upgrade hurdleCon:

Cannot create new packages (easily)Logging views historically in SQL Server 2000 not availableRuns in 32 bit mode only (WOW)Support ceases in vNext

Common Errors

Need to Install the 2005 Backward Compatibility Kit2005 DTS Designer Components

In SQL 2008, copy two additional DLL files over and RLL files

Common Errors

Microsoft Package Upgrade Wizard

Built into SQL Server 2005/2008Pros:

FreeWorks on simple packages

Cons:Does not handle ODBCOnly handles a few types of text file use casesNo Dynamic Properties TaskNo UDL or legacy database support in data pumpPackages only have about a 20% chance of working

Sample Upgrade Project Plan

Scope and Number of PackagesHow long will it take you to migrate each type of taskUse a tool to migrateUpgrade the ActiveX Script Task logicTest, test and test

DTS xChange Feature HighlightsProfiles DTS packages to help with a conversion project planRapidly converts DTS Packages to SSIS (2005 or 2008) and applies SSIS best practicesConverts tasks that are not handled by the existing SQL Server conversion wizardIncludes a SSIS logging repository and reports for trending and alertingIncludes BI xPress for new SSIS packages

Monitor Packages

A Few of the Conversion Rules

Support for migration of children packagesLogging to SQL Server, Text Files or via Event HandlersConsolidate Connection ManagersCreate configuration files automaticallyCreate package transactionsCheckpointsNULL handling

Other Advantages

Handles text files properlyHandles NULLs properlyHandles ODBC for a sourceMigrates Dynamic Properties TasksAdvanced profiler to estimate your projectFull validation of the output of the migration94%+ package success rate in customer migrations over tens of thousands of packages

ActiveX Script Migration

All tools mentioned migrate DTS ActiveX to ActiveX in SSISActiveX migrates to SSIS but you would not want to keep it there and it may not runNeed for ActiveX Script Task has been replaced with built-in, easy to maintain SSIS tasks

File System Object = File System TaskMail objects = Send Mail Task (now has SMTP)ADO objects = Execute SQL Task

DeActiveX Script Conversions
