2.1.Create a Backup Copy of the Primary Database Datafiles
冷备份主库

2.2.Create a Control File for the Standby Database
成备库的控制文件

2.3.Prepare an Initialization Parameter File for the Standby Database
准备备库的参数文件initPRODSTD.ora
①在主库中将主库的pfile文件传输到备库中[oracle@ocm1 ~]$ cd /u01/app/oracle/product/10.2.0/db_1/dbs[oracle@ocm1 dbs]$ lltotal 6744-rw-rw---- 1 oracle oinstall 1544 Mar 25 09:59 hc_PROD.dat-rw-r----- 1 oracle oinstall 12920 May 3 2001 initdw.ora-rw-r----- 1 oracle oinstall 8385 Sep 11 1998 init.ora-rw-r--r-- 1 oracle oinstall 1827 Mar 25 09:39 initPROD.ora-rw-rw---- 1 oracle oinstall 24 Mar 18 10:18 lkPROD-rw-r----- 1 oracle oinstall 5120 Mar 18 09:54 orapwPROD-rw-r--r-- 1 oracle oinstall 318 Mar 17 20:37 pfile.ora-rw-r----- 1 oracle oinstall 6832128 Mar 19 19:51 snapcf_PROD.f-rw-r----- 1 oracle oinstall 4608 Mar 25 09:57 spfilePROD.ora[oracle@ocm1 dbs]$ scp initPROD.ora ocm2.localdomain:/u01/app/oracle/product/10.2.0/db_1/dbsThe authenticity of host 'ocm2.localdomain (192.168.1.156)' can't be established.RSA key fingerprint is de:2a:4c:d0:b2:20:88:4c:a2:72:24:11:50:4b:d6:74.Are you sure you want to continue connecting (yes/no)? yesWarning: Permanently added 'ocm2.localdomain,192.168.1.156' (RSA) to the list of known hosts.oracle@ocm2.localdomain's password: initPROD.ora 100% 1827 1.8KB/s 00:00 [oracle@ocm1 dbs]$
