最近在做NBU ORACLE备份的恢复测试，执行恢复时报错ORA-27211: Failed to load Media Management Library，具体处理过程如下：
一、错误信息
执行命令：
run { ALLOCATE CHANNEL ch00 TYPE SBT_TAPE; send ‘NB_ORA_CLIENT=192.168.x.x‘; send ‘NB_ORA_SERV=nbu5230‘; restore controlfile from ‘/ctrl_dTESTDB_u0at7lkpa_s10_p1_t981127978‘; release channel ch00; }
报错信息：
RMAN-00571: =========================================================== RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS =============== RMAN-00571: =========================================================== RMAN-03009: failure of allocate command on ch00 channel at 07/10/2018 16:16:09 ORA-19554: error allocating device, device type: SBT_TAPE, device name: ORA-27211: Failed to load Media Management Library Additional information: 2
二、错误原因
由于数据库的Lib库不包含NBU的库文件，所以执行rman恢复时报错
三、解决方案
将NBU的库文件放入Oracle库文件目录下即可
[oracle@node1 oracle]$ ln -s /usr/openv/netbackup/bin/libobk.so64 /U01/app/oracle/product/11.2.0.4/lib/libobk.so
[oracle@node1 oracle]$ sbttest /etc/hosts
[oracle@node1 oracle]$ sbttest /etc/hosts The sbt function pointers are loaded from libobk.so library. -- sbtinit succeeded -- sbtinit (2nd time) succeeded sbtinit: Media manager supports SBT API version 2.0 sbtinit: Media manager is version 5.0.0.0 sbtinit: vendor description string=Veritas NetBackup for Oracle - Release 7.7.2 (2016011116) sbtinit: allocated sbt context area of 8 bytes sbtinit: proxy copy is supported -- sbtinit2 succeeded -- regular_backup_restore starts ................................
四、知识扩展
1.NBU数据库恢复脚本
run { allocate channel t1 type ‘sbt_tape‘; allocate channel t2 type ‘sbt_tape‘; allocate channel t3 type ‘sbt_tape‘; send ‘NB_ORA_CLIENT=192.168.x.x‘; send ‘NB_ORA_SERV=nbu5230‘; set until sequence 12 thread 1; restore database; #switch datafile all; recover database; release channel t1; release channel t2; release channel t3; }
2.归档日志恢复
run { allocate channel t1 type ‘sbt_tape‘; allocate channel t2 type ‘sbt_tape‘; send ‘NB_ORA_CLIENT=192.168.x.x‘; send ‘NB_ORA_SERV=nbu5230‘; restore archivelog from sequence 8 until sequence 12 INCARNATION ALL; release channel t1; release channel t2; }
3.其他恢复
更改还原路径： RMAN> set archivelog destination to ‘/u01/backup‘; 还原全部备份归档： RMAN> restore archivelog all; 归档日志范围恢复： RMAN> restore archivelog from sequence 8 until sequence 12; RMAN> restore archivelog sequence between 8 and 12; 从低sequence开始恢复： RMAN> restore archivelog from sequence 5; RMAN> restore archivelog low sequence 5; 从高sequnece截止恢复： RMAN> restore archivelog until sequence 110; RMAN> restore archivelog high sequence 108; 按时间恢复： RMAN> restore archivelog from time ‘sysdate-7‘;
