环境：solaris 10，oracle 11.2.0.4 2nodes rac
症状：rman备份报错以下
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
ORA⑴9554: error allocating device, device type: SBT_TAPE, device name:

1.尝试使用以下方法配置rman参数 没法解决
使用CONFIGURE CHANNEL DEVICE TYPE 'SBT_TAPE' CLEAR;
CONFIGURE DEVICE TYPE SBT_TAPE CLEAR; 命令；
以下：
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

RMAN>CONFIGURE DEFAULT DEVICE TYPE TO Disk;
old RMAN configuration parameters:

new RMAN configuration parameters:

new RMAN configuration parameters are successfully stored

full resync complete
RMAN>CONFIGURE DEVICE TYPE SBT_TAPE CLEAR;

2：对照原来可以正常备份的AIX
发现$ORACLE_HOME/lib/下有 libobk文件
sfc3rac1:/apps/oracle/product/10.2.0/lib$ ls -lrt |grep bobk
lrwxrwxrwx 1 oracle oinstall 35 Jul 02 2010 libobk.a -> /usr/omni/lib/libob2oracle8_64bit.a
sfc3rac1:/apps/oracle/product/10.2.0/lib$
但是坚持当前solaris 下oracle home中没有此软连接文件
DP安装路径下是有次文件

手动建立软连接
ln -s /opt/omni/lib/libob2oracle8_64bit.so /u01/app/oracle/product/11.2.0/dbhome_1/lib/libobk.so
oracle-home下已有此文件
[oracle@nsfc3rac2:/u01/app/oracle/product/11.2.0/dbhome_1/lib]$ ls -lrt |grep bob
lrwxrwxrwx 1 oracle oinstall 36 Dec 5 10:43 libobk.so -> /opt/omni/lib/libob2oracle8_64bit.so
[oracle@nsfc3rac2:/u01/app/oracle/product/11.2.0/dbhome_1/lib]$
重新启动备份 可以正常备份
