VERIFY VERIFY Verifies the current page statically. In a static verification, no sets are walked. This is similar to an RMU/VERIFY/OPTIONS=SEGMENT command, except RdbALTER VERIFY checks only the current page. If the database uses space area management and the current page is a data storage page, the SPAM entry for the current page is checked for correct value. If the current page is a SPAM page, the page is checked for valid format, but the individual SPAM entries are not checked for correctness. Error messages are issued if the page is corrupt.
