This parameter defines special commands to be sent to the external backup library, using the following settings for backup_dev_type:
backup_dev_type = rman_util|rman_disk|rman_stage
For more information on the Oracle SEND command, see the Oracle documentation. Many suppliers of backup libraries for RMAN use this command to pass additional control information to the backup library.
Syntax: rmand_send = “’<command>’”
You can also send the different commands to specified backup channels:
rman_send = (“channel sbt_1 ‘<command1>’ parms=’<parameters1>’”, “channel sbt_2 ‘<command2>’ parms=’<parameters2>’”)
