Hi, Can anyone help me on this.
I have an AIX system at V5.1 with v7.2 fix9 running. I know that you can install 2 versions of db2 on AIX. Installed v8.1 fix4 (without a problem).
The problem is when I try creating v8.1 instance. Even after v8.1 install, v7.2 instance creation ... is fine. This is the following message I get. Tried uninstalling and reinstalling v8.1 with no luck in instance creation.

./db2icrt -a SERVER -p 50000 -s ese -u fencev8 db2inst1

==========================
DBI1281E The database manager configuration file could not be
initialized.

Explanation:

An error occurred when attempting to initialize the database
manager configuration file. A DB2 instance could not be created
or migrated.

User Response:

Refer to the log file for problem determination. Resolve the
problem and try the command again. If the problem persists,
please contact IBM Support.

Hi,

Do you have a instance created with the name db2inst1?
test change the name.

I do not have any existing v8.1 instances. I already tried number of ways. I recreated the id and tried. I also used a different instance id and different fence id. Still didn't have much luck.

Hi,

Have you performed a clean un-install, as it may find traces of the previous install. Did you drop all the users and re-create them fresh as the profiles hold some values.

Please change user names and verify.

Regards

Nitin.

Hi, The install was clean. To make sure I did a reinstall. The userids were recreated. Also tried a different user. Before the reinstall, yes cleaned up failed installs. There were no failed installs. V8.1 install was smooth.

Thnx
Srini

Check root's PATH which should not reference sqllib/bin (or other folders under sqllib). If these references are present, remove them from root's PATH and resubmit the db2icrt command. DB2 does not support root as an instance owner.

This is what I found at the IBM website when I had the same problem

Make sure that the ID is valid, login in as the id first, don't su to it, Make sure the password is valid,

Hi, Great. Thanks a lot for your help. It worked. I didn't use root to create instance but looks like someone in the past tested an instance and a version 7.2 instance path was placed. Can you please give me the site you were talking about? Thanks again.
