 CEKAB provides POS&ATM terminal
operator, acquiring, switching and
issuing services
 Over a billion transactions per year
on HP Integrity, BASE24, and our
own batch system
EDB - who are we?
 EDB - Nordic leadership

Background to migration
 Continuously growing business
 Dual site decision - 24/7/365 is the reality
– CEKAB has used Tandem and BASE24
since 1986
– Reliable hardware, software and
vendors
– Strategic decision to continue cooperation in a 24/7/365 world
 Invest in the future,
– not in old technology
– each machine handles peak transaction
throughput

What we feared prior to the project?
 Remember K to S migration?
– Huge infrastructure changes, everything had to
be touched
– Migration from Sages to SWAN-boxes
– No support of X.21
– CISC to RISC processor
 We feared
– RISC to EPIC would be like CISC to RISC
– CEKAB was on BASE24 V6.4 and ACI had
tested HP Integrity on V6.5
– Long down-time to move CAFs across
– Testing communication is difficult in test
environment
– Start up from PC
– We didn’t want to be first
Was it plug & play?
 Hardware migration was a
piece of cake
– S => I is a small technology
step compared to K => S
– “Only” a switch to a new
powerful processor
 New accelerator worked well
 Excellent support from HP
– Skilled personnel
– Great assistance
 System met our expectations
Go-live night was a success
 CEKAB was first in the world to migrate Base24
from S to I
 Early to run Connect:Direct and MQ on HP
Integrity
 Go-live was successful, up and running after 1
hour and 17 minutes.
– Golden Gate replication from old to new
machine minimized the outage
– HW worked fine
– Communication controllers worked fine
– 3rd party SW worked fine
– Own batch system worked fine
– But we are all humans – especially at 5 AM…
What went wrong at go-live?
 Cables had been incorrectly labeled
 Format2
– ZIP program for Format2 files failed
– A few homegrown utilities did not work
with Format2 or had not been upgraded
 Batch programs
– A few batch programs did not use
CPU0-3
– Some had been moved across, but not
recompiled
 Forgot to warm-boot change of X.25
address
What went wrong during the project?
 Communication
– Too few Ethernet controllers ordered
– Telco reluctant to install TokenRing at new
sites.
Saved by IBM!- stopped supporting FEPs
SNASW (SNA/IP) replaced
SNA/TokenRing
– 2 fiber interfaces in core-switches failed,
detected weeks before go-live!


 Batch programs – became a problem
– Could not move COBOL programs across,
had to be accelerated with new accelerator,
OCA. Unforeseen tests as a result
– Recompile Cobol programs once more when
High Pin had to be used
What we had not counted for?
 Miscellaneous
– Debugger did not work with
Format2
– Switch from Inspect to Visual
inspect
– Long time to get a fix for MQ
– Insufficient experience of 3rd party
programs
– Internal view – it is an technical
project
– OS upgrade three times, from
H06.04 to H06.07
What we did not do?
 CEKAB did not follow
recommendations to upgrade current
OS version to G06.27 on the Smachine before moving software
across to HP Integrity.
– This was abandon, due to cost and
time constraints.
– It turned out well 
After go-live experiences
 Customers perceived go-live as a success
and were impressed by the short down-time
 HP Integrity will last many years, CPU
utilization is still low
 Java works better than before
 Batch file creation and delivery is faster.
– File creation is faster due to rapid I/O and
powerful CPUs
– File delivery time has decreased
substantially due to the communication
hardware upgrade
So far each go-live has been a success
 November 5th, 2006 live on HP Integrity
 February 2007 2nd HP Integrity in
production and GG Warm Stand-by
 April 2007 GG Hot Stand-by
 Sep 16th, 2007, new version of GG and
go-live of active-active with D24
 Nov 5th first live traffic in secondary
machine
Conclusions
 CEKAB was first in the world to
migrate Base24 from S to I
 Go-live was successful, up and
running after 1 hour and 17 minutes
 Much easier migration than K to S
 Nothing to be afraid of – almost plug
& play
 We would to it again…

“HP was the obvious partner. We
have a long history of working
with HP, so it was a safe choice for
us. We trust the people and the
hardware is extremely reliable.”
