How to Clone an 11.2 Grid Infrastructure Home and Clusterware (Doc ID 1413846.1)
Cloning An Existing Oracle11g Release 2 (11.2.0.x) RDBMS Installation Using OUI (Doc ID 1221705.1)
1 首先备份源端的oracle软件：
[oracle@test 19.9.0]$ tar -cvf /home/oracle/source.tar .
目标端创建相关目录，修改oracle 环境变量 修改操作系统配置 安装相关rpm包，（参考安装文档此处不做记录）
2 将其传输到目标端然后解压
tar -xvf /tmp/source.tar
3 删除和修改部分文件
修改listener.ora文件
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
)
删除dbs 目录下的不需要的文件
设置oracle home变量
export ORACLE_HOME=/u01/app/oracle/product/23.0.0/dbhome_1
cd $ORACLE_HOME/bin
./orabasehome
4 运行以下命令以使用 Oracle 通用安装程序 （OUI） 克隆安装：
$ORACLE_HOME/perl/bin/perl $ORACLE_HOME/clone/bin/clone.pl ORACLE_BASE="/u02/app/oracle" ORACLE_HOME="/u02/app/oracle/product/19.9.0/db_1" OSDBA_GROUP=dba OSOPER_GROUP=oper OSBACKUPDBA_GROUP=backupdba OSDGDBA_GROUP=dgdba OSKMDBA_GROUP=kmdba OSRACDBA_GROUP=racdba -defaultHomeName
碰到的问题：
安装过程中网络断了，清空ORACLE_HOME 再次恢复的时候，再次执行报错OUI-10197:Unable to create a new Oracle Home at，执行如下操作，删除安装信息后再次执行
[root@localhost oraInventory]# rm -rf *
[root@localhost oraInventory]# pwd
/u02/app/oraInventory
克隆日志如下：
oracle@localhost 19.9.0]$ $ORACLE_HOME/perl/bin/perl $ORACLE_HOME/clone/bin/clone.pl ORACLE_BASE="/u02/app/oracle" ORACLE_HOME="/u02/app/oracle/product/19.9.0/db_1" OSDBA_GROUP=dba OSOPER_GROUP=oper OSBACKUPDBA_GROUP=backupdba OSDGDBA_GROUP=dgdba OSKMDBA_GROUP=kmdba OSRACDBA_GROUP=racdba -defaultHomeName
