Problem installing IBM's DB2 Express-C server.

[haramraj]

When I tried installing DB2 Express-C server on my Ubuntu 12.04. and when I ran the 'db2prereqcheck' I got the error message

I just want to ask, whether Ubuntu 12.04 is supported by IBM's DB2 server? and if yes, how to install DB2 properly?

The answer is shown in what was displayed from the tool.

DBT3514W The db2prereqcheck utility failed to find the following 32-bit library file: "/lib/libpam.so*".
Install the 32-bit library.

sudo apt-get install libpam0g:i386

That's nice, but:

tommy@sabre - sudo apt-get install libpam0g:i386
[sudo] password for tommy:
Reading package lists... Done

libpam0g is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.


So, why can't DB2 find the file? Because I have libpam.so.0, in a subdirectory of /lib:

tommy@sabre - find /lib -name "*libpam*" -print
/lib/i386-linux-gnu/libpam.so.0.83.0
/lib/i386-linux-gnu/libpam.so.0
/lib/i386-linux-gnu/libpam_misc.so.0
/lib/i386-linux-gnu/libpamc.so.0.82.1
/lib/i386-linux-gnu/libpam_misc.so.0.82.0
/lib/i386-linux-gnu/libpamc.so.0

Linking libpam.so.0 still failed, but copying it to /lib worked. It wouldn't surprise me if this causes a problem down the road, though.

Thank you.

create a symlink to it


sudo ln -s /lib/i386-linux-gnu/libpam.so.0 /lib/libpam.so.0
