Netbackup Done status 6 解决方法-原创手记-慕课网

中心某应用系统使用Netbackup备份软件进行备份。监控邮件告警Nbu备份失败，登录NBU Master服务器进行查看。之前也写过一篇关于status 6的报错解决方法，大家可以看看。http://yangjunfeng.blog.51cto.com/539796/989435

Done status 6：the backup failed to back up the requested files;

赛门铁克官方建议出现 status 6可以到备份脚本所在路径下，找到.out的日志文件进行检查。

root@emdb2 # cat emdb2hot_database_backup.sh.out

Script /opt/oracle/ora_nbu_backup/emdb2hot_database_backup.sh

后询问此数据库管理员其升级过数据库PSU，那么应该就是Netbackup与Oracle直接的link出现问题导致。

nbu在备份是需要调用oracle lib库文件，symantec bin目录下提供了一个脚本来创建link（在数据库服务器上执行）。

oracle@emdb2 # pwd

/usr/openv/netbackup/bin

oracle@emdb2 ./oracle_link

All Oracle instances should be shutdown before running this script.

Please log into the Unix system as the Oracle owner for running this script

Do you want to continue? (y/n) [n] y

LIBOBK path: /usr/openv/netbackup/bin

ORACLE_HOME: /opt/oracle/app/oracle/product/11.2.0.3/db_1

Oracle version: 11.2.0.3.0

Platform type: x86_64

Linking LIBOBK:

ln -s /usr/openv/netbackup/bin/libobk.so64 /opt/oracle/app/oracle/product/11.2.0.3/db_1/lib/libobk.so

Done

这样就会在$ORACLE_HOME/lib/下面生成libobk.os文件，重新发起任务备份成功。
