Unlocking the Configure Database Module
Occasionally, the Maximo "configuring database" flag will get set (or remain set after a db edit), preventing any further database configuration. If you're sure that there's no changes pending, logon via SQL Query Analyzer as SYSADM and issue the following. Note that the "N" and "CONFIGURING" must be upper case.
USE database UPDATE maxvars SET varvalue='N' WHERE varname='CONFIGURING'
