Agenda
Die Zielsetzung:
• Migration / Transition Ihrer “mission critical” Applikationen auf die neueItanium Plattform unter Berücksichtigungvon:
•time to market
•Minimierung der Risiken
• Beibehaltung der Funktionalität derApplikation bzw. Chance zum Redesign selbstgeschriebener Software
• Standardisierung und KonsolidierungIhrer Softwarelandschaft
• Zusicherung der “business continuity”
Transition basicsTechnology Driven Change
• Change is inevitable during the lifecycle of an IT system
• The distinction between heavy-weight migration and simple evolution is the magnitude of the change
• Magnitude of change needs to be evaluated at system level, key factors include:
• Business Processes• Solutions architecture• Applications versions• Database structure• Operational practices• Physical assets

Transition to Itanium
ü Allgemeinesü Hardwareü Betriebssystemeü Applikationen und Daten
Agenda
Transition basicsSelecting the ‘right’ level of change
•Incorporate new technologies within context of existing solutions framework•Mapping existing solution architecture into logically ‘equivalent’ HP-UX on Itanium®platform• ‘Equivalent’ includes moderate
capacity enhancement within current solutions architecture
•Driven by evolving business needs rather than Itanium®technology•Significant changes in solutions structure• E.g.: New applications, major
database reorganization
Re-StructuringRe-Hosting
in general:
- because of the high-performance Itanium chipset some of the I/O interface cards, memory etc. should be renewed
- most of the HP storage systems are going to be recertified for Itaniumsystems
specific:- PA-Risc: some newer systems are Itanium ready: replacethe PA-Risc chip by Itanium2
- Alpha/MIPS: fully new hardware
- IA32: fully new hardware

Transition of applications
Transition of applicationshp UNIX® Application Portfolio
§ Large overlap between Tru64™UNIX® and HP-UX™ PA-RISC™application portfolios§ Customers running on Tru64 UNIX (and most other OS) should expect to run the same applications on HP-UX- At the same application version level
on HP-UX during the transition interval
§ Many applications will permit co-existence of different OS-application server nodes
Application environment is preserved when re-hosting on HP-UX

http://h30097.www3.hp.com/transition/modules.html
Aries - Binary translation possibilities
• Compatibility by traditional porting
• Limited availability of application source code
• Cumbersome recompilation process
• Potential dependency on porting tools
• Separate porting needed for each version
• Compatibility by binary emulation
• Source code not needed
• No recompilation• No dependency on
porting tools• Once implemented,
works for all applications
Aries Features and design goals• Transparency
• Absolutely no user intervention
• Completeness• Support for most of the PA-RISC/HP-UX applications,
both 32-bit and 64-bit
• Correctness and Reliability• Emulation of all PA-RISC instructions• Emulation of the exact PA-RISC/HP-UX
environment
• Performance• Acceptable levels of performance over a range of
different types of applications
• Exactly PA-RISC/HP-UX-like interface• Bundled with the OS, kernel support for transparency• Run PA applications on IPF/HP-UX the same way as
you run on PA-RISC/HP-UX
Aries Performance Summary• Integer applications show a slowdown factor of
2x to 4x• Floating-point applications show a slowdown
factor of 3X to 6x• Suggestion to recompile long-running, compute
intensive apps for IPF/HP-UX platform for higher performance
• System-intensive/user-interactive apps run at speed almost comparable to native PA-RISC/HP-UX run
Key benefits•Binary compatibility through
Aries dynamic code translation technology—no recompilation
ü Source code compatibility from PA-RISC to Intel®Itanium® Processor Family—single source code stream
ü Data compatibility between PA-RISC and Itanium Processor Family—no data conversions
HP-UX 11i compatibility

Database Migration Planning Assistant (DBPMA) Tool
• For Oracle databases • Extracts system table information from database• Customer sends XML file to HP to generate report• “Estimator tool” uses measured reference system data for
Export & Import to estimate database migration times• Reports out
• Estimated total time for Export & Import• Top to longest time tables to migrate
Scripts to assist Oracle database migrations
A collection of scripts to assist in the process of migrating Oracle databases from Tru64 UNIX to HP-UX Itanium 2
• DBuilder• “Builds” the framework of scripts to facilitate the creation of a
target database, based on the physical & logical structure of the source database
• DLoader• A mechanism to implement scheduling and bulk data transfer
using Export and Import
• DCompleter• A utility to generate scripts which control the scheduling and
execution of post data load operations
Transition of dataUnder Investigation - File mover tool• Five possible parts to this tool:
• List files to move and record attributes• Specify conversion requirements• Move files from source to target• Convert data format (endian swap)• Verification
