在asmnode 节点 查看initdbasm.ora 文件，确保target database 处于归档模式，否则duplicate 会报错
[oracle@asmnode dbs]$ pwd
/u01/app/oracle/product/11.2.0/db_1/dbs
[oracle@asmnode dbs]$ ls -l
total 28
-rw-rw---- 1 oracle asmadmin 1544 Apr 25 21:49 hc_dbasm.dat

[oracle@asmnode dbs]$ cat initdbasm.ora
SPFILE='+DG_DATA/dbasm/spfiledbasm.ora'
在asmnode 节点 用oracle 用户创建 参数文件 abc.ora 文件
[oracle@asmnode dbs]$ sqlplus / as sysdba;
sql> create pfile='?/dbs/abc.ora' from memory;
在asmnode 节点 用oracle 用户创建备份集
run {
allocate channel ch00 device type disk;
sql 'alter system checkpoint';
backup as compressed backupset database
include current controlfile format '/u01/backup/DB_%T_%U'
plus archivelog delete all input format '/u01/backup/ARCH_%T_%U';
release channel ch00;
}
单纯归档备份， archivelog 必须紧接着 all
run {
allocate channel ch00 device type disk;
sql 'alter system checkpoint';
backup as compressed backupset archivelog all delete all input format '/u01/backup/arch_%T_%U';
release channel ch00;
}
备份过程中均有备份集的存放路径输出
查看备份集
[oracle@asmnode backup]$ cd /u01/backup/
[oracle@asmnode backup]$ ls -l
total 251104
-rw-r----- 1 oracle asmadmin 42496 May 11 16:48 ARCH_20160511_24r5b7av_1_1
-rw-r----- 1 oracle asmadmin 2560 May 11 16:49 ARCH_20160511_27r5b7cq_1_1

-rw-r----- 1 oracle asmadmin 1114112 May 11 16:49 DB_20160511_26r5b7co_1_1
把备份集拷贝到asmnodedup 节点的相同路径下，如果不是相同路径下，可通过ln -s 来解决
[oracle@asmnode backup]$ scp /u01/backup/ARCH* oracle@10.1.1.36:/u01/backup/
[oracle@asmnode backup]$ scp /u01/backup/DB* oracle@10.1.1.36:/u01/backup/
在 asmnodedup 节点 创建pfile参数文件
export ORACLE_SID = dbasmd
[grid@asmnodedup dbs]$ vi /u01/app/grid/product/11.2.0/grid_1/dbs/initdbasmd.ora
*.audit_file_dest='/u01/app/oracle/admin/dbasmd/adump'

*.log_file_name_convert=('+DG_DATA/dbasm/','/u01/app/oracle/oradata/dbasmd/')
需要修改db_file_name_convert，log_file_name_convert
或者直接设定 db_create_file_dest
在 asmnodedup 节点 创建必要的目录
mkdir -p /u01/app/oracle/admin/dbasmd/adump
mkdir -p /u01/app/oracle/diag/rdbms/dbasmd/dbasmd/trace
mkdir -p /u01/app/oracle/diag/rdbms/dbasmd/dbasmd/cdump
mkdir -p /u01/app/oracle/oradata/dbasmd/{controlfile,datafile,tempfile,onlinelog}
需要保证target和auxiliary 库的sys用户口令相同。
从asmnode 拷贝原数据库的密码文件到 asmnodedup 节点 oracle 用户 $ORACLE_HOME/dbs 目录下，然后重命名
[oracle@asmnode dbs]$ scp /u01/app/oracle/product/11.2.0/db_1/dbs/orapwdbasm oracle@10.1.1.36:/u01/app/oracle/product/11.2.0/db_1/dbs
[oracle@asmnodedup dbs]$ mv orapwdbasm orapwdbasmd
或者在 asmnodedup 使用 orapwd 创建一个和target database 的sys一样密码的密码文件。
在 asmnodedup 节点 grid 用户 用asmcd 查看一下
[grid@asmnodedup bin]$ ./asmcmd
ASMCMD> ls -l
State Type Rebal Name
MOUNTED EXTERN N DG_DATA/
静态监听，两个节点都要添加
在 asmnode 节点 grid 用户下添加静态监听
[grid@asmnodedup admin]$ vi /u01/app/grid/product/11.2.0/grid_1/network/admin/listener.ora
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(ORACLE_HOME = /u01/app/oracle/product/11.2.0/db_1)
(SID_NAME =dbasm)
)
)
在 asmnodedup 节点 grid 用户下添加静态监听
[grid@asmnodedup admin]$ vi /u01/app/grid/product/11.2.0/grid_1/network/admin/listener.ora
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(ORACLE_HOME = /u01/app/oracle/product/11.2.0/db_1)
(SID_NAME =dbasmd)
)
)
在 asmnode， asmnodedup 节点 重启监听，看如输出状态为 UNKNOWN 就表示静态监听已添加成功
[grid@asmnodedup admin]$ lsnrctl stop
[grid@asmnodedup admin]$ lsnrctl start
Services Summary...

在 asmnode，asmnodedup 节点, oracle 用户下 添加 tnsnames.ora 文件
tns_dbasm =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = asmnode)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = dbasm)
)
)
tns_dbasmd =
