About the Speaker
•BI consultant Specializing in SSIS, SSRS • .Net Developer•Four years experience with SQL Server•Currently developing new products with
Pragmatic Works for SQL Server•Blog on Pragmaticworks.com
Why choose SSIS?•64bit support•Parallel in-memory multi buffer
architecture helps to load data several times faster than DTS.
•Logging, Configuration, CheckPoint etc.•Source Safe Integration because
everything is XML•Many new Tasks (e.g. Script Task, For
Each Loop, XML Task etc.) that replace need for ActiveX
Less Maintenance… Faster Development… Faster Performance
DTS vs. SSIS 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 machine•Pulling 1 million rows out and writing to
SQL table with no transformation•SSIS 65% + faster than DTS•Adding transformation would add more
SSIS advantage
Project Options
•Run DTS in 2005 or 2008▫Missing the package logs▫Runs under 32 bit
•Upgrade using MS Wizard▫Not compatible with most package
•Upgrade using DTSxchange▫Minutes per package
•Starting from scratch▫About 3-5 hrs per package
Demo
•Running DTS package in SQL Server 2005/2008
Microsoft Package Upgrade Wizard•Built into SQL Server 2005/2008
▫Does not handle ODBC▫Only handles a few types of text file use
cases▫No Dynamic Properties Task▫No UDL or legacy database support in
data pump▫Packages only have about a 20% of working
What is Involved in Upgrading?
•Scope and Number of Packages•How long will it take you to migrate each
type of task•How to migrate, Manual or Tool•Upgrade the ActiveX Script Task logic,
Manual•Test, test and test
Microsoft Package Upgrade Wizard•Demo
Feature Highlights• Profiles DTS packages to help with a conversion
project plan• Rapidly converts DTS Packages to SSIS (2005 or
2008) and applies SSIS best practices• Converts tasks that are not handled by the
existing SQL Server conversion wizard•Handles Flat files Properly•Shows Warnings not just success
DTS xChange Profiler
DTS xChange Migration
A Few of the Conversion Rules
•Support for migration of children packages
•Creates a robust Auditing framework•Consolidate Connections in Connection
Manager•Create configuration files automatically•Create package transactions•Checkpoints•NULL handling
Other Advantages
•Handles text files properly•Handles ODBC for a source•Migrates Dynamic Properties Tasks•Advanced profiler to estimate your project•Full validation of the output of the
migration•92% package success rate in customer
migrations over thousands of packages
Built-in Reports
ActiveX Script Migration
•All tools mentioned migrate DTS ActiveX to ActiveX in SSIS
•ActiveX migrates to SSIS but you would not want to keep it there and it may not run
•Need for ActiveX Script Task has been replaced with built-in, easy to maintain SSIS tasks▫File System Object = File System Task▫Mail objects = Send Mail Task (now has
SMTP)▫ADO objects = Execute SQL Task
