BIP8638
Severity
10 : Warning
Message
The user name that you are installing under (<insert_1>) has more than 8 characters. If you continue and use this later to create DB2 databases then you can encounter problems.
Explanation
You are using a userid to install that is longer than 8 characters. This may give problems if you later try and create DB2 databases whilst running under this userid.
Response
You can ignore this message and continue, particularly if you are only installing components that do not have a database dependency. If you are going to create databases following this installation, then we suggest that you cancel this installation and sign on with a userid that conforms to DB2 requirements.
