1. 建立輔助例項金鑰檔案orapwtestdb3
[oracle@testdb3 ~]:testdb1> orapwd
Usage: orapwd file= entries= force= ignorecase= nosysdba=
where
file - name of password file (required),
password - password for SYS will be prompted if not specified at command line,
entries - maximum number of distinct DBA (optional),
force - whether to overwrite existing file (optional),
ignorecase - passwords are case-insensitive (optional),
nosysdba - whether to shut out the SYSDBA logon (optional Database Vault only).
There must be no spaces around the equal-to (=) character.
[oracle@testdb3 ~]:testdb1> orapwd file=/app/oracle/ora11g/dbs/orapwtestdb3 password="123456" entries=30;

[oracle@testdb3 dbs]:testdb1>
orapwd引數：
file : 指定金鑰檔名和路徑
password：指定sys使用者密碼
entries：指定擁有sysdba許可權的使用者最大數
force：如果檔案存在，是否覆蓋
file和password是必填引數。
2. windows環境需要建立Oracleservice，Linux等不需要
>oradim -new -sid testdb3
3. 配置初始化引數檔案testdb3init.ora

[oracle@testdb1 dbs]:testdb3> tnsping testdb3
[oracle@testdb1 admin]:testdb3> rman target sys/123456@testdb3
都返回正確資訊，則ok！
6. 檢視原testdb1是有完整的備份（沒有可以直接backup database）
備份資料庫和控制檔案
run{
allocate channel c1 type disk;
allocate channel c2 type disk;
allocate channel c3 type disk;
allocate channel c4 type disk;
backup current controlfile;
backup database format '/backup/testdb1/testdb1_full_%U';
release channel c1;
release channel c2;
release channel c3;
release channel c4;
}
7. rman連線目錄庫和輔助例項

8. 執行命令
[oracle@testdb1 admin]:testdb3> rman target sys/123456@testdb1 auxiliary sys/123456@testdb3
catalog start with '/backup/testdb1/';
run {
allocate auxiliary channel c1 type disk;
allocate auxiliary channel c2 type disk;
allocate auxiliary channel c3 type disk;
allocate auxiliary channel c4 type disk;
duplicate target database to testdb3;
release channel c1;
release channel c2;
release channel c3;
release channel c4;
}

1. 建立輔助例項金鑰檔案orapwtestdb3
[oracle@testdb3 ~]:testdb1> orapwd
Usage: orapwd file=
where
file - name of password file (required),
password - password for SYS will be prompted if not specified at command line,
entries - maximum number of distinct DBA (optional),
force - whether to overwrite existing file (optional),
ignorecase - passwords are case-insensitive (optional),
nosysdba - whether to shut out the SYSDBA logon (optional Database Vault only).
There must be no spaces around the equal-to (=) character.
[oracle@testdb3 ~]:testdb1> orapwd file=/app/oracle/ora11g/dbs/orapwtestdb3 password="123456" entries=30;

-rw-r-----. 1 oracle oinstall 4608 Nov 12 14:41 spfiletestdb1.ora
[oracle@testdb3 dbs]:testdb1>
orapwd引數：
file : 指定金鑰檔名和路徑
password：指定sys使用者密碼
entries：指定擁有sysdba許可權的使用者最大數
force：如果檔案存在，是否覆蓋
file和password是必填引數。
2. windows環境需要建立Oracleservice，Linux等不需要
>oradim -new -sid testdb3
3. 配置初始化引數檔案testdb3init.ora

[oracle@testdb1 dbs]:testdb3> tnsping testdb3
[oracle@testdb1 admin]:testdb3> rman target sys/123456@testdb3
都返回正確資訊，則ok！
6. 檢視原testdb1是有完整的備份（沒有可以直接backup database）
備份資料庫和控制檔案
run{
allocate channel c1 type disk;
allocate channel c2 type disk;
allocate channel c3 type disk;
allocate channel c4 type disk;
backup current controlfile;
backup database format '/backup/testdb1/testdb1_full_%U';
release channel c1;
release channel c2;
release channel c3;
release channel c4;
}
7. rman連線目錄庫和輔助例項

8. 執行命令
[oracle@testdb1 admin]:testdb3> rman target sys/123456@testdb1 auxiliary sys/123456@testdb3
catalog start with '/backup/testdb1/';
run {
allocate auxiliary channel c1 type disk;

allocate auxiliary channel c3 type disk;
allocate auxiliary channel c4 type disk;
duplicate target database to testdb3;
release channel c1;
release channel c2;
release channel c3;

}
