恢复目录的创建
rc库上操作192.168.3.222
sqlplus / as sysdba
create tablespace rmans;
create user rmans identified by 123456 default tablespace rmans QUOTA UNLIMITED ON rmans;
select * from dba_roles where role like '%CATA%';
select * from dba_sys_privs WHERE GRANTEE LIKE '%CATA%';
grant recovery_catalog_owner to rmans;
这是在rc库上的重做操作（如果有问题，就重来一遍）
drop user rmans cascade;
drop tablespace rmans including contents;
create tablespace rmans;
create user rmans identified by 123456
default tablespace rmans
quota unlimited rmans;//这一行一定要加，否则会报第一个错（无权限的错）
grant recovery_catalog_owner to rmans;
alter user rmans quota unlimited on rmans;//如果创建用户时没有加，就这样加上去
目标库上操作192.168.3.202
rman catalog rmans@my
create catalog;
connect target / 这条语句是在同一个会话中操作或者下面的语句（重新连接）都可以
rman target / catalog rmans
register database;
有两个报错需要处理一下
报错一：
RMAN> create catalog;
error creating config_update
ORACLE error from recovery catalog database: ORA-01950: no privileges on tablespace 'RMANS'
ORACLE error from recovery catalog database: ORA-00942: table or view does not exist
只需要下面这条语句就可以了
alter user rmans quota unlimited on rmans;
报错二：
RMAN> create catalog;
error creating db
ORACLE error from recovery catalog database: ORA-00955: name is already used by an existing object
ORACLE error from recovery catalog database: ORA-00942: table or view does not exist
在目标库上丢弃重建就可以了
drop catalog;
drop catalog;
exit
rman catalog rmans@my
create catlog;
===================
RMAN> drop catalog;
recovery catalog owner is RMANS
enter DROP CATALOG command again to confirm catalog removal
RMAN> drop catalog;
recovery catalog dropped
RMAN> exit
Recovery Manager complete.
[oracle@oracle1 ~]$ rman catalog rmans@my
