Review the list of users, groups, and roles in the above output to ensure only approved users, groups, and roles are assigned.

How it is fixed

Fix method: Guidance or infrastructure patch

Revoke this permission from any unauthorized users. 1. Connect to the Db2 database. db2 => connect to <dbname> 2. Run the following command: db2 => REVOKE SCHEMAADM ON SCHEMA <schema> FROM USER <username>
