Oracle Database Backup Scheme

This component of the RMAN environment is a copy of the primary database that is updated using archived logs created by the primary database.

During the execution phase, if more than one channel is allocated, then RMAN can execute certains commands in parallel so that all of the channel's target database sessions are concurrently executing an RPC call.

This classification of the degree of durability avoids the problem of lost transactions.

Here, a transaction commits as soon as it commit log record is written to stable storage at the primary site.

This RAID level is known as memory-style error correcting-code organization.

It is a block of RMAN job commands that is stored in the recovery catalog.

It includes archived redo logs and flashback logs.

In RAID level 3, disk controllers can detect whether a sector has been read correctly.

This component of the RMAN environment contains the metadata that RMAN uses to perform its backup and recovery operations.

A transaction can lock a data item in exclusive mode only if it is not locked at all.

This RAID level refers block-interleaved parity organization, uses block-level striping.

The node that originates the distributed transaction.

RMAN uses a command language interpreter that can execute commands in interactive or batch mode.

This component of the RMAN environment allows RMAN to backup to a storage system such as tape.

This RAID level refers to disk arrays with striping at the level of blocks, but without any replication.
