catalog備份資料庫及RMAN儲存指令碼

環境說明：


提前配置好兩個庫的監聽與tnsnames.ora
IP：10.100.25.13 為目標資料庫  
IP：10.100.25.14 為恢復目錄資料庫（catalog database）


以下操作全部都在恢復目錄資料庫下執行：


1.為恢復目錄建立一個表空間，表空間名稱是 catalogts。使用者名稱是catalogdemo 密碼是
oracle。給這個使用者賦予恢復目錄擁有者許可權。


SQL> create tablespace catalogts datafile'/home/oracle/app/oradata/catalog01.dbf' size 50m autoextend on;


Tablespace created.


SQL> create user catalogdemo identified by oracle default tablespace catalogts quota unlimited on catalogts;


User created.


SQL> grant recovery_catalog_owner to catalogdemo;


Grant succeeded.




2.使用RMAN用catalogdemo使用者連線到恢復目錄資料庫。在 catalogts 表空間中建立恢復目錄。


[oracle@11g ~]$ rman catalog catalogdemo/oracle@10.100.25.14:1521/orcl

connected to recovery catalog database


RMAN> create catalog tablespace catalogts;


recovery catalog created


3.使用RMAN，連線到目標資料庫和恢復目錄資料庫。


[oracle@11g ~]$ rman target sys/oracle@10.100.25.13:1521/orcl catalog catalogdemo/oracle@10.100.25.14:1521/orcl

connected to target database: ORCL (DBID=1388303183)
connected to recovery catalog database


5.在恢復目錄中註冊目標資料庫，執行resync catalog 命令來同步控制檔案和恢復目錄。


RMAN> register database;


database registered in recovery catalog
starting full resync of recovery catalog
full resync complete


RMAN> resync catalog;


starting full resync of recovery catalog
full resync complete




RMAN> list incarnation;

catalog RMAN儲存指令碼


指令碼的分類
    local : 在rman連線的目標資料庫下建立的指令碼，此類指令碼僅僅適用於當前目標資料庫。即是針對特定的資料庫建立的rman指令碼
    global : 能夠在恢復目錄註冊的任意目標資料庫中執行
    如：create global script XXXX comment 'A script for full backup to be used with any database' {。。。。}


a:  建立rman本地儲存指令碼
RMAN> create script whole_backup { backup database; }


created script whole_backup


b：執行rman本地儲存指令碼
RMAN> run { execute  script whole_backup; }


executing script: whole_backup

c:  檢視當前恢復目錄內的指令碼
list [global | all] script names
       
RMAN> list script names;


d:  更新指令碼
    replace [global] script scrip_name {....}
    replace [global] script script_name from file '<dir>'  --從檔案更新指令碼


RMAN> replace  script whole_backup { allocate channel ch1 type disk;
allocate channel ch2 type disk;
backup incremental level 0 database plus archivelog  delete input
format '/home/oracle/rmanbak/db_%d_%U'
tag=db_inc_0;
release channel ch1;
release channel ch2; }2> 3> 4> 5> 6> 7> 


replaced script whole_backup


e:  檢視指令碼內容
RMAN> print script whole_backup;


printing stored script: whole_backup
{ allocate channel ch1 type disk;
allocate channel ch2 type disk;
backup incremental level 0 database plus archivelog  delete input
format '/home/oracle/rmanbak/db_%d_%U'
tag=db_inc_0;
release channel ch1;
release channel ch2; }


f： 刪除指令碼
delete [global] script script_name
