Revoking database server access from mapped users (UNIX, Linux)

Use the REVOKE ACCESS FROM statement to remove surrogate user properties from specific mapped users.

Only user informix or a DBSA can run the REVOKE ACCESS FROM statement.

The REVOKE ACCESS FROM statement does not affect any access privileges of the HCL OneDB™ user account name that accesses the database server through an OS-level account on the host computer.

Example:

User informix or a DBSA can run the following statement on a system that supports mapped users, and one of the mapped users is user bob:

REVOKE ACCESS FROM bob;

This statement entirely removes the access of user bob to the database server, except when one or both of the following is true:

• PUBLIC is mapped to surrogate user properties. In this case, user bob still retains the same access privileges that the PUBLIC group holds.
• User bob is also a user account on the HCL OneDB host computer with database server access.
