DB2 V8.1
AIX 5300-05-03

I am trying to install DB2 on AIX machine but it fails when creating the instance. When I was running the setup, it asked me if I want to create the instance in 32 bit or 64 bit and I chose the 64 bit since the LPAR is 64 bit (both Kernel and Hardware). When it came to the step creating the instance, it failed with the following message in "db2icrt.log.307358" file (Also the db2setup.log file after the --------------- below):

Thanks for any help.

Did you run setup as a root user?

I sure did......................

Then I think you'll need to figure out why "touch: /tmp/db2idbm.tmp.442462 cannot create"

??????????????

Hi,

If your running as root, check the permission on /tmp directory.

If /tmp is not writable then installation will fail.

And give the hostname output as well in the next reply.
