Done status 6: the backup failed to back up the requested files;

 

Symantec officially recommends that you go to the path where the backup script is located and find the. out log file for check.

Root @ emdb2 # cat emdb2hot_database_backup.sh.out

Then ask the database administrator to upgrade the database PSU, which should be caused by a problem in the direct link between the master and slave databases.

In the backup, nbu needs to call the oracle lib library file. The symantec bin directory provides a script to create a link and execute it on the database server ).

Oracle @ emdb2 # pwd

/Usr/openv/netbackup/bin

Oracle @ emdb2./oracle_link

All Oracle instances shocould 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:/opt/oracle/app/oracle/product/11.2.0.3/db_1

Oracle version: 11.2.0.3.0

Platform type: x86_64

Linking LIBOBK:

Ln-s/usr/openv/netbackup/bin/libobk. so64/opt/oracle/app/oracle/product/11.2.0.3/db_1/lib/libobk. so

Done

In this way, the libobk. OS file is generated under $ ORACLE_HOME/lib/, and the task backup is initiated again.
