1. 建立 RMAN 用户（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. 建立恢复目录（create_catalog.rcv）
connect catalog rmanuser/1234@cata
create catalog tablespace users;
connect target sys/1234@testdb
register database;
3. 建立恢复目录 shell 脚本（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 导出（exprman.sql）
userid=rmanuser/1234
buffer=32768
owner=rmanuser
file=/home/oracle/dbbak/rman.dmp
rows=Y
compress=Y
5. RMAN 导出 shell 脚本（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. 整库备份（backup_full.rcv）
connect target sys/1234@testdb
connect catalog rmanuser/1234@cata
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. 整库备份 shell 脚本（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
