DB2 Help

Database name

A database name must be specified when a database is created. All databases managed by the same database manager instance must have unique alias names.

DB2 database names are displayed as fields in the system database directory, the local database directory, and the database connection services directory.

A database name consists of 1 - 8 characters from the following list:

Letters (A-Z, a-z)
Digits (0-9)
Special characters (@, #, $, -)

Also, a database name:

Cannot contain DBCS characters
Must begin with A-Z, a-z, @, #, or $
Is not case-sensitive
Cannot contain embedded blanks

Note:

To avoid potential problems, do not use the special characters @, #, and $ in a database name if you intend to use the database in a communications environment. Also, because the characters @, #, and $ are not common to all keyboards, do not use them if you plan to use the database in another country.
