Oraclecreatecatalog创建恢复目录

1.在catalog数据库上创建cat用户的表空间 SQL create tablespace cat datafile 'DATADG/orcl/datafile/cat.dbf' size 512M; 2.创建cat用户 SQL Create user cat identified by cat temporary tablespace temp default tablespace cat Quota unlimited on cat

1.在catalog数据库上创建cat用户的表空间
SQL> create tablespace cat datafile '+DATADG/orcl/datafile/cat.dbf' size 512M;

2.创建cat用户
SQL> Create user cat identified by cat temporary tablespace temp default tablespace cat Quota unlimited on cat;

3.授权给cat用户
SQL> grant connect,resource to cat;

SQL> grant recovery_catalog_owner to cat;

4. 连接到catalog数据库
[oracle@orcl admin]$ rman catalog cat/cat@orcl

5.创建恢复目录
RMAN> create catalog;

6. 在catalog中注册target数据库
[oracle@orcl admin]$ rman catalog cat/cat@orcl target sys/oracle@python;

RMAN> register database;

------------------------------------------------------------------------------------------------

7.注销target数据库

[oracle@orcl admin]$ rman catalog cat/cat@orcl target sys/oracle@python;

RMAN> unregister database;
或
为了能注销数据库，需要获得数据库的标识码（DB_ID）和数据库键值（DB_KEY）。其中连接目标数据库时将会获得DB_ID
连接到目标数据库，查询db表：
SQL> select * from db;
DB_KEY DB_ID CURR_DBINC_KEY
---------- ---------- --------------
1 3021445076 2
SQL> execute dbms_rcvcat.unregisterdatabase(1,3021445076);
