-check content of /usr/openv/netbackup/bp.conf



1) check link between Oracle and Netbackup.
lrwxr-xr-x   1 oracle     dba             36 Mar  7  2011 -> /usr/openv/netbackup/bin/libobk.sl64

Below are the API library for different Platform.

NetBackup API libraries

Platform        Oracle    Library Name     
AIX             32-bit    libobk.a

1 Use RMAN to make a backup directly to disk. Do not use NetBackup.
2 Use RMAN with NetBackup to create a backup.
3 Check the /usr/openv/netbackup/logs/dbclient directory permissions. They should be set to 777.
4 Look for a log file in /usr/openv/netbackup/logs/dbclient
If no log file exists, libobk is not linked into Oracle properly.

Note: you dont need to shutdown all instances.
You can create softlink without shutting down Database.
ln -s /usr/openv/netbackup/bin/libobk.sl64 /u01/app/oracle/product/

if you want to create softlink safely , execute /usr/openv/netbackup/bin/oracle_link as below.

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: /u01/app/oracle/product/
Oracle version:
Linking LIBOBK (64 bits):
Moving to
ln -s /usr/openv/netbackup/bin/libobk.sl64 /u01/app/oracle/product/

Please check the trace file located in /tmp/make_trace.18515
to make sure the linking process was successful.

2) Check using sbttest.

The sbt function pointers are loaded from library.

               [os_res_size pl_res_size block_size block_count]>
               <-libname sbt_library_name>

3) Read More into logfiles.

4) check below directory and files
