The CONFIGURE command can be used to show or set parameter values.
RMAN includes a number of parameters which initially have default values.
The CONFIGURE command can be used to get or set parameter values.
The default values are as follows:
RMAN> SHOW ALL; CONFIGURE RETENTION POLICY TO REDUNDANCY 1; CONFIGURE BACKUP OPTIMIZATION OFF; CONFIGURE DEFAULT DEVICE TYPE TO DISK; CONFIGURE CONTROLFILE AUTOBACKUP OFF; CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '%F'; CONFIGURE DEVICE TYPE DISK PARALLELISM 1 BACKUP TYPE TO BACKUPSET; CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1; CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; CONFIGURE MAXSETSIZE TO UNLIMITED; CONFIGURE ENCRYPTION FOR DATABASE OFF; CONFIGURE ENCRYPTION ALGORITHM 'AES128'; CONFIGURE COMPRESSION ALGORITHM 'BASIC' AS OF RELEASE 'DEFAULT' OPTIMIZE FOR LOAD TRUE; CONFIGURE ARCHIVELOG DELETION POLICY TO NONE; CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/u01/app/oracle/product/11.2.0/dbhome_1/dbs/snapcf_TEST.f'; # default
To set a configuration parameter use the CONFIGURE command. For example:
RMAN> CONFIGURE BACKUP OPTIMIZATION OFF;
To unset a configuration parameter use the CLEAR keyword. For example:
RMAN> CONFIGURE BACKUP OPTIMIZATION CLEAR;
RMAN> CONFIGURE CHANNEL DEVICE TYPE DISK CLEAR;
Non-standard parameters can also be cleared. For example:
RMAN> CONFIGURE CHANNEL 1 DEVICE TYPE DISK CLEAR;
Non-default configuration parameter values are reported in the V$RMAN_CONFIGURATION dynamic performance view.
In Oracle 11.2 this view has the following columns:
Column Name | Data Type | Notes |
CONF# | NUMBER |   |
NAME | VARCHAR2(65) |   |
VALUE | VARCHAR2(1025) |   |
In Oracle 11.2 V$RMAN_CONFIGURATION contains the following rows:
