O/S : Aix ver 5
DB : DB2 UDB v8.2
I am trying to install db2 client on AIX , after the installation it shows as

% db2level
DB21085I Instance "db8inst1" uses "32" bits and DB2 code release "SQL08020"
with level identifier "03010106".
Informational tokens are "DB2 v8.1.1.64", "s040812", "U498350", and FixPak "7".
Product is installed at "/usr/opt/db2_08_01".

Whereas I wanted a 64 bit client.

On Aix when I execute

bootinfo -K I get as

[root@xxxx] bootinfo -K
64
[root@xxxx] bootinfo -y
64

What shld I be doing to get on to 64 bit DB2 client.

Thank You,
SB

Download correct software.

if correct soft is installed specify this when executing db2icrt

Have a look at the "db2icrt" and the "db2iupdt" commands. If I remember correctly, both have an option "-w" with which you can set/change the bit-width to be used for your instance.
