RMAN 備份常用指令碼 && RAC RMAN
OS：RHEL 3；RMAN 備份資訊儲存在恢復目錄中，恢復目錄建立在所要備份資料庫（testdb）以外的另一個數據庫（cata）上。
1. 建立 RMAN 使用者（create_rmanuser.sql）
create user rmanuser identified by 1234 default tablespace users temporary tablespace temp;
grant connect,resource,recovery_catalog_owner to rmanuser;
exit;
2. 建立恢復目錄（create_catalog.rcv）
connect catalog
create catalog tablespace users;
connect target sys/[email protected]
register database;
3. 建立恢復目錄 shell 指令碼（create_catalog.sh）
#!/bin/bash
cd $HOME
. .bash_profile
export ORACLE_SID=cata
export NLS_LANG="american_america.WE8ISO8859P1"
cd $HOME/dbbat/recover
sqlplus sys/1234 as sysdba @create_rmanuser.sql
rman cmdfile=create_catalog.rcv msglog=$HOME/dblog/create_catalog.log
cd $HOME
. .bash_profile
4. RMAN 匯出（exprman.sql）
userid=rmanuser/1234
buffer=32768
owner=rmanuser
file=/home/oracle/dbbak/rman.dmp
rows=Y
compress=Y
5. RMAN 匯出 shell 指令碼（exprman.sh）
#!/bin/bash
cd $HOME
. .bash_profile
export ORACLE_SID=cata
export NLS_LANG="american_america.WE8ISO8859P1"
cd $HOME/dbbat/backup
exp parfile = exprman.sql
cd $HOME
. .bash_profile
6. 整庫備份（backup_full.rcv）
connect target sys/[email protected]
connect catalog rmanuser/[email protected]
run{
allocate channel c1 type disk;
allocate channel c2 type disk;
allocate channel c3 type disk;
backup full tag 'dbfull' format '/u02/oradata/flash_recovery_area/full%u_%s_%p' database include current controlfile;
sql 'alter system archive log current';
backup filesperset 3 format '/u02/oradata/flash_recovery_area/arch%u_%s_%p' archivelog all delete all input;
release channel c1;
release channel c2;
release channel c3;
}
crosscheck backup;
delete noprompt expired backup;
delete noprompt obsolete;
resync catalog;
7. 整庫備份 shell 指令碼（backup_full.sh）
#!/bin/bash
cd $HOME
. .bash_profile
cd $HOME/dbbat/backup
rman cmdfile=backup_full.rcv msglog=$HOME/dblog/backup_full.log
/home/oracle/dbbat/backup/exprman.sh
run{
allocate channel c1 type disk;
allocate channel c2 type disk;
allocate channel c3 type disk;
backup incremental level 0 cumulative tag 'db0' format '/u02/oradata/flash_recovery_area/db0%u_%s_%p' database skip readonly;
sql 'alter system archive log current';
backup filesperset 3 format '/u02/oradata/flash_recovery_area/arch%u_%s_%p' archivelog all delete all input;
release channel c1;
release channel c2;
release channel c3;
}
crosscheck backup;
delete noprompt expired backup;
delete noprompt obsolete;
resync catalog;
9. 0 級備份 shell 指令碼（backup_0.sh）
#!/bin/bash
cd $HOME
. .bash_profile
cd $HOME/dbbat/backup
rman cmdfile=backup_0.rcv msglog=$HOME/dblog/backup_0.log
/home/oracle/dbbat/backup/exprman.sh
run{
allocate channel c1 type disk;
allocate channel c2 type disk;
allocate channel c3 type disk;
backup incremental level 1 cumulative tag 'db1' format '/u02/oradata/flash_recovery_area/db1%u_%s_%p' database skip readonly;
sql 'alter system archive log current';
backup filesperset 3 format '/u02/oradata/flash_recovery_area/arch%u_%s_%p' archivelog all delete all input;
release channel c1;
release channel c2;
release channel c3;
}
crosscheck backup;
delete noprompt expired backup;
delete noprompt obsolete;
resync catalog;
11. 1 級備份 shell 指令碼（backup_1.sh）
#!/bin/bash
cd $HOME
. .bash_profile
cd $HOME/dbbat/backup
rman cmdfile=backup_1.rcv msglog=$HOME/dblog/backup_1.log
/home/oracle/dbbat/backup/exprman.sh
run{
allocate channel c1 type disk;
allocate channel c2 type disk;
allocate channel c3 type disk;
backup incremental level 2 cumulative tag 'db2' format '/u02/oradata/flash_recovery_area/db2%u_%s_%p' database skip readonly;
sql 'alter system archive log current';
backup filesperset 3 format '/u02/oradata/flash_recovery_area/arch%u_%s_%p' archivelog all delete all input;
release channel c1;
release channel c2;
release channel c3;
}
crosscheck backup;
delete noprompt expired backup;
delete noprompt obsolete;
resync catalog;
13. 2 級備份 shell 指令碼（backup_2.sh）
#!/bin/bash
cd $HOME
. .bash_profile
cd $HOME/dbbat/backup
rman cmdfile=backup_2.rcv msglog=$HOME/dblog/backup_2.log
/home/oracle/dbbat/backup/exprman.sh
