Oracle RMAN-优快云博客

    Creating recovery catalog is a 3 step process .The recovery catalog is stored in the default tablespace of the recovery catalog schema. SYS cannot be the owner of the recovery catalog.

1. Creating the Recovery Catalog Owner
2. Creating the Recovery Catalog
3. Registering the target database

恢复目录数据库所需空间大小：
Size of recovery catalog schema depends on
a) The number of databases monitored by the catalog.
b) The rate at which archived redo log generates in the target database
c) The number of backups for each target database
d) RMAN stored scripts stored in the catalog

Typical Recovery Catalog Space Requirements for 1 Year：
SYSTEM tablespace：90 MB
Temp tablespace：5 MB
Rollback or undo tablespace：5 MB
Recovery catalog tablespace：15 MB for each database registered in the recovery catalog
Online redo logs：1 MB each (3 groups, each with 2 members)

1、创建恢复目录用户
恢复目录数据库上操作：
[oracle@wjw]$ sqlplus / as sysdba;
SQL> create tablespace catalog datafile '/u01/app/oracle/oradata/orcl/catalog01.dbf' size 2g;
SQL> create user rman identified by rman default tablespace catalog temporary tablespace temp quota unlimited on catalog;
SQL> grant connect,resource,recovery_catalog_owner to rman;

2、创建恢复目录
目标数据库上操作：
[oracle@source ~]$ cd $ORACLE_HOME/network/admin
[oracle@source admin]$ vi tnsnames.ora
内容如下：
catadb =
(DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 10.0.2.117)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
    )
)
[oracle@source admin]$ rman catalog rman/rman@catadb
