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

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
