1. schedule downtime: sitemap->maintenance->manage downtime schedules->schedule downtime

2. OAM restricted mode

2.1 update contextfile, set s_trusted_admin_client_nodes to be the desktop ip address. (need to add load balancer ip address to if it is used).
2.2 Run adautocfg
2.3 Unlock database account ad_monitor and change password. Default password is lizard.
2.4 Run adadmin to put system in maintenance mode.
2.5 Start apache in restricted mode: adaprstctl.sh start|stop
2.6 login to OAM: http://{host}:{port}/servlets/weboam/oam/oamLogin
