Oracle 版本为10204。

veritas netbackup版本为7.0

解决方法：

如果oracle是64位的使用下面的命令
cd ${ORACLE_HOME}/lib
ls -l libobk.so
If libobk.so exists.
mv libobk.so libobk.so.orig
ln -s /usr/openv/netbackup/bin/libobk.a64.1 libobk.sa

[oracle@backupdatabase lib]$ ls -l libobk.so
lrwxrwxrwx 1 oracle dba 13 Feb 27 21:50 libobk.so -> libdsbtsh8.so
[oracle@backupdatabase lib]$ mv libobk.so libobk.so.orig
[oracle@backupdatabase lib]$ ln -s /usr/openv/netbackup/bin/libobk.so libobk.so

修改后，再备份OK
