DP backup error ORA-19554: error allocating device, device type: SBT_TAPE ORA-27211, sbttape

DP backup error ORA-19554: error allocating device, device type: SBT_TAPE ORA-27211, sbttape

Environment: solaris 10, oracle 11.2.0.4 2 nodes rac

Symptom: rman backup reports the following error:

RMAN-00571: ========================================================== ==============================
RMAN-00569: ==================== error message stack follows ==========================
RMAN-00571: ========================================================== ==============================
RMAN-03009: failure of allocate command on dev_0 channel at 12/05/2014 10:25:25
The ORA-19554: error allocating device, device type: SBT_TAPE, device name:
ORA-27211: Failed to load Media Management Library
Additional information: 3986

1. Try to use the following method to configure the rman parameter.

Use configure channel device type 'sbt _ TAPE 'CLEAR;
Configure device type SBT_TAPE CLEAR; command;
As follows:
RMAN> configure channel device type 'sbt _ TAPE 'CLEAR;
Old RMAN configuration parameters are successfully deleted

RMAN> show all;
RMAN configuration parameters are:
Configure retention policy to redundancy 1;
Configure backup optimization off; # default
Configure default device type to 'sbt _ TAPE ';
Configure controlfile autobackup on;
Configure controlfile autobackup format for device type SBT_TAPE TO '% F'; # default
Configure controlfile autobackup format for device type disk to '% F'; # default
Configure device type SBT_TAPE PARALLELISM 1 backup type to backupset; # default
Configure device type disk parallelism 1 backup type to backupset; # default
Configure datafile backup copies for device type SBT_TAPE TO 1; # default
Configure datafile backup copies for device type disk to 1; # default
Configure archivelog backup copies for device type SBT_TAPE TO 1; # default
Configure archivelog backup copies for device type disk to 1; # default
Configure maxsetsize to unlimited; # default
Configure encryption for database off; # default

RMAN> configure default device type to Disk;
Old RMAN configuration parameters:
Configure default device type to 'sbt _ TAPE ';
New RMAN configuration parameters:
Configure default device type to disk;
New RMAN configuration parameters are successfully stored
Starting full resync of recovery catalog
Full resync complete

RMAN> configure device type SBT_TAPE CLEAR;
RMAN configuration parameters are successfully reset to default value

RMAN> show all;
RMAN configuration parameters are:
Configure retention policy to redundancy 1;
Configure backup optimization off; # default
Configure default device type to disk;
Configure controlfile autobackup on;

Ii. Compare the AIX that can be backed up normally

Found the libobk file under $ ORACLE_HOME/lib /.

Sfc3rac1:/apps/oracle/product/10.2.0/lib $ ls-lrt | grep bobk
Lrwxrwxrwx 1 oracle oinstall 35 Jul 02 2010 libobk. a->/usr/omni/lib/libob2oracle8_64bit.a

However, this soft connection file does not exist in oracle home under solaris.

There is a file in the DP installation path
