I am checking an existing DB2 installation on Red Hat Linux and I see
that root owns files in the db2 instance home directory.
Stuff like:
../sqllib/adm/db2chparm
../sqllib/adm/db2stop
../sqllib/adm/db2genp
../sqllib/adm/db2start
The instance owner can access the files because it has membership of
the owning group but I would have thought that the instance owner
would have owned all files in it's home directory. Does it matter?
