How does the Oracle Rman tool view the current configuration parameters?

Rman uses the show command to display the current configuration parameters. For example, use show all to display ALL current configurations.

RMAN> show all;

RMAN configuration parameters:

Configure retention policy to recovery window of 3 DAYS;

Configure backup optimization off; # default

Configure default device type to disk; # default

Configure controlfile autobackup on;

Configure controlfile autobackup format for device type disk to 'D:/backup/% F'

Configure device type disk parallelism 1; # default

Configure datafile backup copies for device type disk to 1; # default

Configure archivelog backup copies for device type disk to 1; # default

Configure maxsetsize to unlimited; # default

Configure snapshot controlfile name to 'F: ORAHOME1DATABASESNCFJSSWEB. ORA '#

Default

RMAN>

Note: the configuration item is followed by # default, indicating that the item is still the initial configuration and has not been modified.

This command is also quite flexible to use, and later it keeps up with different types of configuration parameters, that is, different types of configuration can be displayed, such:

Show channel;

Show device type;

Show default device type;
