I have a problem. I have installed DB2 v8 on a Linux box and there
were some problems with the creation of the TOOLSDB due to the
installation media. I decided that I would reinstall. I ran the
db2_deinstall, then deleted the users db2inst1, dasusr1, db2fenc1.
When I tried to reinstall the machine remembers the das instance and
can't create a new one. Because I deleted the users I can't drop the
das instance or the othere instances.
Is there a way to get a complete clean install of the database. I
know most of the files are under /opt/IBM/db2/... but not all.
What can I do to get this fixed? I don't know what to do. I can't
find any real documentation about how to handle this.

Thank you,

Steven

I am running redhad advanced Server 2.4.9. I managed to recreate the
instance owner accounts and dropped the instances. I can't run dasdrop
it comes back saying that it ran successfully but there is an error
that db2admin is not found. I run the daslist and the instance is
still listed. Any thoughts on how to get rid of the das instance?

The simplest, and most dangerous, is to remove /var/db2. If you have
no other DB2 whatsoever on the system, that's the last bit of cleanup
required.

If you have another DB2 running, e.g., DB2 v7, then you need to be a
bit more surgical about what you clean up. That's probably not the
case here, but I want to make it explicit in case someone else happens
upon this thread later.

If you don't have any other DB2 instances created on the machine (i.e.
'db2ilist' returns nothing, and 'daslist' returns only the DAS instance
that no longer exists, you can remove the files in /var/db2.

Before you do this, I would shut down the the db2fmcd, by commenting
out the entry in /etc/inittab and issuing 'telinit q'.

Good luck.

That should be done by rpm automatically ;-)

Indeed, but I don't think that this person wanted to uninstall / reinstall
DB2. Just recreate instances.
