User ID
The user ID for the DB2 administrator. This must be an existing
user ID with Administrator authority. In addition:
- On Windows(R) platforms, the user must be a member of the Administrators
group.
- On UNIX(R) platforms:
- The user's Primary group can be any general group (such as
other, dbsysadm or db2iadm).
There might be some groups that do not work correctly as the
user's primary group when configuring the database. For example, if the user's
primary group on Linux is
users, problems might occur.
- The user root must be a member of the user's primary group.
If root is not a member of this group, add root as a member of the group.
- For best results, the user's login shell should be the Korn shell script
(/usr/bin/ksh).
- The user's password must be set correctly and ready to use, For example, the
password cannot be expired or waiting for a first-time validation of any kind.
(The best way to verify that the password is correctly set is to telnet to the same
computer and successfully log in with that user ID and password.)
- The user must have a home directory and must be the owner of the home
directory.
- The group ownership of the user's home directory must be the user's primary group.
- When configuring the database, it is not necessary, but only customary, to specify the home
directory of the user ID as the database location.
However, if you specify some other location, the user's home directory still must
have 3 to 4 MB of space available. This is because DB2 creates
links and adds files into the home directory of the instance owner (that is, the User)
even though the database itself is elsewhere.
