Oracle 版本为10204。
veritas netbackup版本为7.0
解决方法：
To link Oracle9i（10g也适用）with NetBackup for Oracle on UNIX
1. Become the Oracle user.# www.linuxidc.com
su - oracle
2. Shutdown all of the Oracle instances (SIDs).
sqlplus
sys/change_on_install as sysdba (login/password)
shutdown
exit
3.aix (32-bit or 64-bit) using 32-bit Oracle software.
a. Create a symbolic link from Oracle to the NetBackup API library
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.so.1 libobk.so
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
