NET-BACKUP Configuration For Oracle



If the oracle_link script is executed, it will display a message similar to the following and backups of the Oracle instance will not utilize the NetBackup implementation of the Oracle SBT API.

Following is the work around to fix the issue. This is linux/Unix specific. For AIX one has to do modifications as per environment. 

On the client host, manually create the needed symbolic link between the Oracle installation and the NetBackup installation.

1)     Confirm that the NetBackup shared libraries are present on the client host and of the correct version.

$ cd /usr/openv/netbackup/
$ ./bin/goodies/support/versioninfo –f bin/libobk.so
======= bin/libobk.so =======
@(#) NetBackup_7.1 1234567890

2)     Check for an existing libobk being used by Oracle and rename if present.

$ cd $ORACLE_HOME/lib
$ ls libobk.so
libobk.so
$ mv libobk.so libobk.so.orig

3)     Create the symbolic link to the NetBackup shared library.

$ ln –s /usr/openv/netbackup/bin/libobk.so libobk.so
  
 An updated oracle_link script is included in NetBackup release update 7.1.0.4 and release 7.5.
