Database users

Informix®

Until version 11.70.xC2, Informix database users must be created at the operating system level and must be members of the 'informix' group.

Starting with 11.70.xC2, Informix supports database-only users with the CREATE USER instruction, as in most other db servers.

Any database user must have sufficient privileges to connect and use resources of the database; user rights are defined with the GRANT command.

Netezza®

Netezza users must be registered in the database with the CREATE USER command, for example:
CREATE USER name WITH PASSWORD 'pswd' IN GROUP ...

See the Netezza documentation for more details about user creation and database access/security.

Solution

Depending on the application logic (is it a multiuser application?), you have to create one or several Netezza users.
