Chapter 5 Oracle Secure Backup 119 Oracle Secure Backup Daemons An administrative domain uses seven types of OSB daemons Service daemon This daemon runs on the administrative server media server and client. Access to OSB configuration data on the administrative server is provided by the service daemon. It also runs jobs requested by the schedule daemon. On a media server or a client the daemon handles membership in an administrative domain. Schedule daemon This runs only on the administrative server. It is the OSB scheduler. Index daemon This daemon runs only on the administrative server to manage the backup catalog. It starts when a backup is completed or the catalog is accessed for restore or browsing operations. Apache web server daemon This runs only on the administrative server and provides the Web tool interface. NDMP daemon Th is daemon runs on a media server and a client and provides data communication between them. Robot daemon This runs on a media server and manipulates tapes in a tape library. The service daemon starts one robot daemon for each tape library when a tape manipulation is needed. Proxy daemon This daemon runs on a client to verify user access for SBT backup and restore operations. Host Access Modes Communicating to a host in an administrative domain is possible through two access modes Primary For primary access mode OSB is installed on a host. The access mode is used by OSB daemons. An Oracle database typically exists on a host accessed via this mode. In OEM it is referred to as native access mode. In OSB Web tool it is called OB access mode. .
