解决办法：nbu在备份时需要调用oracle lib库文件，bin目录下提供了此脚本
[root@HA-zcqsmzq-tsvm01 bin]# su - oracle
[oracle@HA-zcqsmzq-tsvm01 ~]$ cd /usr/openv/netbackup/bin/
[oracle@HA-zcqsmzq-tsvm01 bin]$ ls oracle_link
oracle_link
[oracle@HA-zcqsmzq-tsvm01 bin]$ ./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
