RMAN登陆及连接target数据库的步骤方法
一、 方法一：
a) [Oracle@odd-oelr4u8 ~]$ rman target sys/oracle@PROD1521 catalog catalog_admin/catalog_admin@PROD21521
b)
c) Recovery Manager: Release 10.2.0.1.0 - Production on Mon Jan 20 07:56:30 2014
d)
e) Copyright (c) 1982, 2005, Oracle. All rights reserved.
f)
g) connected to target database: PROD (DBID=248672105)
h) connected to recovery catalog database
i) 该方法指定catalog库并连接了target库，是一种CATALOG Mode
二、 方法二：
a) [oracle@odd-oelr4u8 ~]$ rman target sys/oracle@PROD1521
b) RMAN> connect catalog catalog_admin/catalog_admin@PROD21521
c)
d) connected to recovery catalog database
e) 该方法先连接target库，再指定catalog库，也是一种CATALOG Mode
三、 方法三：
a) [oracle@odd-oelr4u8 ~]$rman
b) RMAN> connect target sys/oracle@PROD1521
c)
d) connected to target database: PROD (DBID=248672105)
e) RMAN> connect catalog catalog_admin/catalog_admin@PROD21521
f)
g) connected to recovery catalog database
h) 该方法先连接rman，再指定连接target库，再指定catalog库，也是一种CATALOG Mode
四、 方法四：
a) [oracle@odd-oelr4u8 ~]$ rman
b)
c) Recovery Manager: Release 10.2.0.1.0 - Production on Mon Jan 20 07:59:21 2014
d)
e) Copyright (c) 1982, 2005, Oracle. All rights reserved.
f)
g) RMAN> connect target sys/oracle@PROD1521
h)
i) connected to target database: PROD (DBID=248672105) --有dbid证明已连接到目标库
j)
k) RMAN> show all;
l)
m) using target database control file instead of recovery catalog --使用控制文件来代替恢复目录数据库存放rman元数据信息
n) RMAN configuration parameters are:
o) CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 30 DAYS;
p) CONFIGURE BACKUP OPTIMIZATION ON;
q) CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default
r) CONFIGURE CONTROLFILE AUTOBACKUP ON;
s) CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/home/oracle/backup/control/controlfile_%F';
t) CONFIGURE DEVICE TYPE DISK PARALLELISM 2 BACKUP TYPE TO BACKUPSET;
u) CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
v) CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
w) CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT '/home/oracle/backup/PROD_%U';
x) CONFIGURE MAXSETSIZE TO UNLIMITED; # default
y) CONFIGURE ENCRYPTION FOR DATABASE OFF; # default
z) CONFIGURE ENCRYPTION ALGORITHM 'AES128'; # default
aa) CONFIGURE ARCHIVELOG DELETION POLICY TO NONE; # default
bb) CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/u01/app/oracle/product/10.2.0/db_1/dbs/snapcf_PROD.f'; # default
cc)
dd) RMAN> connect catalog catalog_admin/catalog_admin@PROD21521
ee)
ff) RMAN-00571: ===========================================================
gg) RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
hh) RMAN-00571: ===========================================================
ii) RMAN-06445: cannot connect to recovery catalog after NOCATALOG has been used
jj) 这种情况是在连接target库之后，做了其他的非连接catalog库的动作，因此系统默认的是NO CATALOG MODE，系统已经默认使用controlfile作为知识库，再相连接catalog库就报错了
kk) 如果想再次使用catalog库，并将controlfile中的内容同步到catalog库中，则需要重新连接target和catalog，并作同步如下：
ll) 采用如上方法一、二、三中的任何一种方式连接target和catalog后，在rman中执行：
mm) RMAN> resync catalog;
nn)
oo) starting full resync of recovery catalog
pp) full resync complete
