1.尝试使用如下方法配置rman参数 无法解决
使用CONFIGURE CHANNEL DEVICE TYPE 'SBT_TAPE' CLEAR; CONFIGURE DEVICE TYPE SBT_TAPE CLEAR; 命令； 如下： 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 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 CONFIGURE ENCRYPTION ALGORITHM 'AES128'; # default CONFIGURE ARCHIVELOG DELETION POLICY TO NONE; # default CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/opt/oracle/product/10.2.0/dbs/snapcf_ge02.f'; # 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; CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '%F'; # default CONFIGURE DEVICE TYPE DISK PARALLELISM 1 BACKUP TYPE TO BACKUPSET; # default CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK 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 CONFIGURE ENCRYPTION ALGORITHM 'AES128'; # default CONFIGURE ARCHIVELOG DELETION POLICY TO NONE; # default CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/opt/oracle/product/10.2.0/dbs/snapcf_ge02.f'; # default
二：对比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

重新启动备份 可以正常备份
