Log groups

A log group is used to multiplex log files across different locations and contains multiple members, which are identical log files. Log groups are used to reduce the impact of a disk failure disaster on the recovery process:

*_LOG_COLUMNS

Lists the columns assigned to log groups. New with Oracle9i.

*_LOG_GROUPS

Lists the tables that are associated with log groups and indicates whether the log group is always used for the table or only when certain columns in the table are modified. New with Oracle9i.
