Database authorization ID Q

Although the DB2 UDB for OS/390 authorization ID of Q owns all control tables, sample tables, and catalog views in QMF, you do not need this authorization ID to install QMF. Without it, however, you need SYSADM authority.

If your authority (as installer) is revoked, the authorities granted during the installation process are also revoked, unless those privileges are also granted by some other authority.
