Danu: Wikipedia over Danu:
In de Keltische mythologie was Danu de (goede) moeder-godin. (Haar tegenhangster was Domnu). Danu was de vrouw van Bile, en was de matriarch van Tuatha Dé Danann, de voornaamste goden van het oude Ierland.
Haar kinderen zijn Dagda, Dian Cecht, Lir, Lugh, Gwydion, Govannnon, Arianrhod, Gilfaethwy en Amaethon. Met Dagda had ze een kind Ogma.
Alternatieve namen: Don (Welsh), Dan, Dana, Dann
Vermoedelijk hebben zowel de rivier de Donau (Danube) als de Rhône (Ro Danus) hun naam te danken aan Danu, zijnde de moederrivier.

4. TPF4.1 usage at KLM:
Current release is TPF4.1 (PUT 19++ ) at KLM since 1996
Total approximately application sources
Assembler application programs: appr. 67 %
C/C++ language application programs: appr. 33 %
TPF connectivity:
Terminals and Printers: appr. 10K+ RES related
Message Switching
Host-to-Host Links: Altéa, AF, NW, WSP e-ticketing, etc.
Misc. non-TPF based KLM applications, e.g. Webfarm
z/TPF Migration

5. Moved to Amadeus Altéa RES in 2007
What functionality?
Moved to Amadeus Altéa RES in 2007
TPF at KLM hosts primary applications:
Corda (reservations, fares, ticketing, inventory)
Codeco (check-in, load & balance)
Cargoal (Cargo booking system)
Firda (Flight information)
TPF at KLM is part of more than 50 service chains among which:
EBT, WebPearl, Bagmanager, Acars, Lido, CISS-Firda, SSCI, ICI, VLC
For KLM via TPF 66M msgs are processed daily with peaks of 1310 msg/sec. During 2007 the number of msgs increased by 23% despite Altéa.
An availability of 99,974% over 2007, incl. 25 planned & 6 unplanned downtimes
z/TPF Migration

6. z/TPF Rationale Support of 64-bit z/Architecture IBM mainframes
Support of new features like encryption, etc.
The complete Amadeus Altéa Suite (RES/INV/DC) cannot be implemented before 2012 replacing TPF based Corda & Codeco
Cargoal will be replaced by AF/KL CARGO Ph-II (2013/2014 ?)
Firda replacement by a non-TPF solution has not been decided
Workload based licensing instead of mainframe model-based makes z/TPF cheaper to run for KLM

7. Overview costs TPF Systems
z/TPF Migration

8. z/TPF project scope: z/TPF EE 1.1 PUT4+
KLM TPF Systems and Communications modifications
Single Source updates TPF applications
Based upon z/VM V5.3 the introduction of z/Linux Red Hat V5.0 environment for z/TPF purposes
Migrate Idefix software management system (based upon z/OS V1.8 and USS/HFS) to z/Linux based z/Idefix, including related tools (compilers, loader, etc.)
Migration of ODF (Online Dump Facility) to z/ODF
z/TPF Migration

9. z/TPF Impact on HW infra
CPU
10% increase in CPU production capacity required for z/TPF ???
2 X IFL required for z/VM & z/Linux
Memory
± three (3) times the memory requirements of TPF4.1 ???
Extra memory required for z/VM & z/Linux (IFL’s: 8 GB)
Database
Small impact on TPF DB.
Extra disk space (SAN) for z/VM (2*80 GB) & z/Linux (2*100 GB)
Tape: No impact

z/TPF Migration

16. z/Online Dump Facility
To improve the ONLINE problem solving activities in TPF, KLM has implemented an tool called OnLine Dump Facility (OLDF).
Rel 5.21 will be adapted for z/TPF -> z/ODF (available mid-June)
Provides the following BASIC capabilities:
Creation of an online displayable MINI-DUMP or SNAPSHOT-DUMP.
Creation of online displayable ERROR-REPORTS and DUMP SUMMARIES.
Registration of occurrences of 'NODUPL' situations in the ERROR-REPORT.
RTA/RTT tape information.
System UP/DOWN information.
PLUS: Breakpoint facility (part of maintenance release end 2008)

General-, Floating point- and Control registers
Around registers (80 bytes per addressed area)
SW00SR and application Stack
Last C stack frame

19. Summary & Conclusion Intended z/TPF cut-over date: 21 March 2009
Very ambitious schedule, but currently still on target
If and when realized: after a relatively late start KLM will be one of the first z/TPF airline systems in production !
We are very interested in exchanging z/TPF migration experiences !
QUESTIONS ?
