rman管理4 CATALOG DB

catalog database 的功能

1)集中存放rman的资料库(备份的元数据),并且可以和target database 的controlfile同步

2)存放rman的备份脚本

catalog database 的配置

1)需要建立一个单独的database

SQL> show parameter name

NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
cell_offloadgroup_name string
db_file_name_convert string
db_name string catdb
db_unique_name string catdb
global_names boolean FALSE
instance_name string catdb
lock_name_space string
log_file_name_convert string
processor_group_name string
service_names string catdb
SQL>

2)建立存放rman 元数据的tablespace

SQL> create tablespace catalogtbs datafile '/u01/app/oracle/oradata/catdb/catalogtbs01.dbf' size 100m;

Tablespace created.

3)建立user,用于管理rman,并授权

SQL> create user rman identified by oracle default tablespace catalogtbs;

User created.

SQL>

SQL> grant connect, resource, recovery_catalog_owner to rman;

Grant succeeded.

4)启动listener ,链接catalog database

----------利用catalog database存放rman 脚本

1)创建脚本(replace 是修改已经存在的脚本)

create script prod_bk {
allocate channel c1 type disk;
allocate channel c2 type disk;
backup database format '/ora_data/prod/full_bk_%U.dbf';
release channel c1;
release channel c2;
}
RMAN> create script prod_bk {
2> allocate channel c1 type disk;
3> allocate channel c2 type disk;
4> backup database format '/ora_data/prod/full_bk_%U.dbf';
5> release channel c1;
6> release channel c2;
7> }

created script prod_bk

created script prod_bk
2)查看脚本信息
RMAN> print script prod_bk;

RMAN> print script prod_bk;

printing stored script: prod_bk
{
allocate channel c1 type disk;
allocate channel c2 type disk;
backup database format '/ora_data/prod/full_bk_%U.dbf';
release channel c1;
release channel c2;
}
------通过catalog database 查看
SQL> col SCRIPT_NAME for a30
SQL> col SCRIPT_COMMENT for a50
SQL> select * from RC_STORED_SCRIPT;

DB_KEY DB_NAME SCRIPT_NAME SCRIPT_COMMENT
---------- -------- ------------------------------ --------------------------------------------------
1 PROD prod_bk

SQL> col text for a50
SQL> select * from RC_STORED_SCRIPT_LINE
2 ;

DB_KEY SCRIPT_NAME LINE TEXT
---------- ------------------------------ ---------- --------------------------------------------------
1 prod_bk 1 {
1 prod_bk 2 allocate channel c1 type disk;
1 prod_bk 3 allocate channel c2 type disk;
1 prod_bk 4 backup database format '/ora_data/prod/full_bk_%U
.dbf';

1 prod_bk 5 release channel c1;
1 prod_bk 6 release channel c2;
1 prod_bk 7 }

7 rows selected.
3)运行脚本
RMAN> run { execute script prod_bk;}
run {execute script prod_bk;}

4) 删除脚本
RMAN> delete script prod_bk;

deleted script: prod_bk
