Solution:

To link Oracle9i (10g also applies) with NetBackup for Oracle on UNIX
1. Become the Oracle user. # www.bkjia.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

If oracle is 64-bit, use the following command
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

After modification, back up OK
