DB2 databases use the user management of the operating system. After the installation of the DB2 database software, the DB2ADMIN operating system user and the DB2USERS group already exist. To generate a database user for PPM, you create a corresponding operating system user and add this user to the DB2USERS group. Through the group membership, the new operating system user receives the privileges required for accessing the DB2 database. The minimum database-related system privileges are: CONNECT, CREATETAB, and IMPLICITSCHEMA.
