oracle 配置 catalog 成功恢复control file
再说catalog 的配置：
1: catalog 数据库上：
  export oracle_sid=ezhoudg
1>在catalog数据库上创建一个表空间供catalog使用
        create tablespace rman_ts datafile '/u02/ezhou/rman01.dbf' size 50m extent management  local uniform size 126k;
   2>在catalog数据库上创建用户并赋予权限
       create user rman_user identified by rman_user default tablespace rman_ts quota unlimited on rman_ts;
       grant recovery_catalog_owner to rman_user;
       grant connect,resource to rman_user;
2: 在主数据库上ezhou：
  vi tnsname.ora (这个文件是在ezhou 和ezhoudg)
  [oracle@aoracle admin]$ vi tnsnames.ora
prd =
(description =
        (address_list =
                (address = (protocol = tcp)(host = 192.168.190.140)(port = 1521))
        )
        (connect_data =
        (sid = ezhou)
        )
)
catalog =
(description =
        (address_list =
                (address = (protocol = tcp)(host = 192.168.190.140)(port = 1521))
        )
        (connect_data =
        (sid = ezhoudg)
        )
)
启动监听lsnrctl start
    在数据库上tnsping catalog
[oracle@aoracle ~]$ tnsping catalog

ok (10 msec)
3: 在主数据库上：
  export oracle_sid=ezhou
  注册主数据库 到catalog
  [oracle@aoracle ~]$ rman target / catalog rman_user/rman_user@catalog

connected to target database (started)
connected to recovery catalog database
rman> create catalog tablespace rman_ts;     
database registered in recovery catalog
starting full resync of recovery catalog
full resync complete
=====================
下面进行测试一下:
[oracle@aoracle ~]$ rman target / catalog rman_user/rman_user@catalog
rman> run {
2> restore controlfile;
3> }
