online backup A backup performed while a database application remains

available for use. The database is placed into a special backup

mode of operation for the time period that the backup

application requires access to the original data objects. During

this period, the database is fully operational, but there may be

a small performance impact and log files may grow very quickly.

Backup mode is required for the short period of the data

replication process only (several seconds). Normal database

operation can then be resumed for the rest of the backup

process.

In some cases, transaction logs may also have to be backed up

to allow a consistent database to be restored.

ownership The ownership of a backup determines who can restore from

the backup. The user who starts an interactive backup is the

session owner. If a user starts an existing backup specification

without modifying it, the session is not considered interactive.

In that case, if the backup owner has been defined in the backup

specification, they remain the session owner. Otherwise, the

session owner becomes the user who started the backup in

question. For the scheduled backups, by default, the session

owner is for the UNIX Cell Manager: root.sys@Cell Manager,

and for the Windows Cell Manager, the user that was specified

during the installation of the Cell Manager. It is possible to

modify the ownership, so that the specific user becomes the

session owner.
