3. 将A机器上的zip包copy到B机器上

[root@localhost inst_env_scripts]# scp 192.168.199.163:/home/oracle/db_1.zip /home/oracle/

The authenticity of host '192.168.199.163 (192.168.199.163)' can't be established.

RSA key fingerprint is cc:d0:c3:de:37:33:a7:cb:91:40:c5:5f:18:07:06:9f.

Are you sure you want to continue connecting (yes/no)? yes

4. 解压zip文件

[root@localhost oracle]# unzip -d / db_1.zip

[root@localhost oracle]# chown -R oracle.oinstall /u01/

5.执行Clone命令

[oracle@localhost ~]$ cd /u01/app/oracle/product/11.2.0/db_1/clone/bin/

[oracle@localhost bin]$ $ORACLE_HOME/perl/bin/perl clone.pl ORACLE_BASE="/u01/app/oracle/" ORACLE_HOME="/u01/app/oracle/product/11.2.0/db_1" OSDBA_GROUP=dba OSOPER_GROUP=oper -defaultHomeName

执行结果如下

./runInstaller -clone -waitForCompletion? "ORACLE_BASE=/u01/app/oracle/" "ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1" "oracle_install_OSDBA=dba" "oracle_install_OSOPER=oper" -defaultHomeName? -defaultHomeName -silent -noConfig -nowait
