RMAN automatic backup script on LINUX

1. create the backup directory oradataback, level 2 directory archback (archive log), rmanscripts (backup script), and rmanlevel0.shrmanlevel1 under rmanscripts. shrmanlevel2.sh File: mkdiroradataback -- home/oracle/app/ora...

1. create the backup directory oradataback, level 2 directory archback (archback), rmanscripts (backup script ),
Create the rmanlevel0.sh rmanlevel1.sh rmanlevel2.sh file under rmanscripts:
Mkdir oradataback
-- Home/oracle/app/oradataback
Chmod 775 oradataback
Chown-R oracle: oinstall/home/oracle/app/oradataback
Touch rmanlevel0.sh rmanlevel1.sh rmanlevel2.sh
Same as above
2. vi edit three files:
Backup File Level 0:
-- Rmanlevel0.sh --
#! /Bin/sh
# Set porfile_env
Export ORACLE_SID = eytdbs # rman level0 backup
Rman log = '/home/oracle/app/oradataback/db_rman0.log' append < Connect target /;
Run
{
Allocate channel c1 type disk;
Backup as compressed backupset incremental level = 0 database format'/home/oracle/app/oradataback/db_level0 _ % T _ % u' tag = 'level0 ';
SQL 'alter system archive log current ';
Backup archivelog all format'/home/oracle/app/oradataback/archback/db_arch _ % T _ % u' delete input;
Release channel c1;
}
EOF
Level 1 backup file:
-- Rmanlevel1.sh --
#! /Bin/sh
# Set porfile_env
Export ORACLE_SID = eytdbs # rman level0 backup
Rman log = '/home/oracle/app/oradataback/db_rman1.log' append < Connect target /;
Run
{
Allocate channel c1 type disk;
Backup incremental level = 1 database format'/home/oracle/app/oradataback/db_level1 _ % T _ % u' tag = 'level1 ';
SQL 'alter system archive log current ';
Backup archivelog all format'/home/oracle/app/oradataback/archback/db_arch _ % T _ % u' delete input;
Release channel c1;
}
EOF
Level 2 backup file:
-- Rmanlevel2.sh --
#! /Bin/sh
# Set porfile_env
Export ORACLE_SID = eytdbs # rman level0 backup
Rman log = '/home/oracle/app/oradataback/db_rman2.log' append < Connect target /;
Run
{
Allocate channel c1 type disk;
Backup incremental level = 2 database format'/home/oracle/app/oradataback/db_level2 _ % T _ % u' tag = 'level2 ';
SQL 'alter system archive log current ';
Backup archivelog all format'/home/oracle/app/oradataback/archback/db_arch _ % T _ % u' delete input;
Release channel c1;
}
EOF
# Note: run the script command in oracle: sh rmanlevel2.sh
3. add automatic task execution:
Set in root and use vi to edit: # crontab-e
0 2 1 ** su-oracle-c/home/oracle/app/oradataback/rmanscripts/rmanlevel0.sh // Run level 0 backup at on the first day of each month
0 2 ** 0 su-oracle-c/home/oracle/app/oradataback/rmanscripts/rmanlevel1.sh // run Level 1 backup at every Sunday
0 2 ** 1-6 su-oracle-c/home/oracle/app/oradataback/rmanscripts/rmanlevel2.sh // run Level 2 incremental backup at every Monday and Saturday
-- View the added task: crontab-l
-- Crontab format:
Minutes | hours | day of month | day of week |
-- Start crond:
/Sbin/service crond start // start the service
/Sbin/service crond stop // close the service
/Sbin/service crond restart // restart the service
/Sbin/service crond reload // reload the configuration
4. test results:
It can be run automatically and data can be backed up successfully, but it is a small problem,
First, the rman backup format % F has always used this format, but since we do not know it today, we can only change it to _ % T _ % u'. I do not know why.
Second, several errors are reported:
RMAN-00558: error encountered while parsing input commands
RMAN-01009: syntax error: found "identifier": expecting one :"......{,"
RMAN-01008: the bad identifier was: EOF
RMAN-01007: at line 1 column 1 file: standard input
I haven't found any problem after searching for a long time. I will study it later.
