...More RMAN Enhancements
Channel failover for BACKUP
COPY command deprecated
- BACKUP command with COPY parameter creates image copies
Default backup can be configured to create
- Normal backupset
- or compressed backupset
- or disk-based image copy
RMAN catalog tablespace created in SYSAUX
Notes:
Additional RMAN enhancements, continued:
RMAN now has the ability to try another channel if a channel fails during backup.
The COPY command is deprecated (will eventually be desupported) because the BACKUP command can be used to create image copies. For example:
RMAN> backup as copy tablespace users;
The CONFIGURE DEVICE TYPE command now supports configuring for normal backupset, compressed backup or image copy. (Note that the image copy option only works for DEVICE TYPE DISK..) For example:
RMAN> show device type ;
RMAN configuration parameters are:
CONFIGURE DEVICE TYPE DISK PARALLELISM 1 BACKUP TYPE TO BACKUPSET; # default
RMAN> configure device type disk backup type to compressed backupset;
new RMAN configuration parameters:
CONFIGURE DEVICE TYPE DISK BACKUP TYPE TO COMPRESSED BACKUPSET PARALLELISM 1;
new RMAN configuration parameters are successfully stored
To alleviate clutter in the SYSTEM tablespace, the RMAN catalog is now by default created in the new SYSAUX tablespace.
