Oracle 之 Cloning $oracle_home (克隆安裝oracle軟體)

 用途：Cloning an Oracle Home ， 可以免去多臺機器重複安裝oracle軟體

1、停止相關程式
[root@node1 bin]# ./crsctl stop cluster -all 
2、打包 dbhome_1 目錄
[root@node1 11.2.0]# cd /u01/app/oracle/product/11.2.0/
[root@node1 11.2.0]# tar -zcvpf db_1.bak db_1/
[root@node1 11.2.0]# ls
db_1 db_1.bak
補充：
Create a ZIP file with the Oracle home (but not the Oracle base) directory.

# zip -r dbhome_1.zip /u01/app/oracle/product/11.2.0/dbhome_1
Do not include the admin, fast_recovery_area, and oradata directories that are under the Oracle base directory. These directories are created in the target installation later, when you create a new database there.

3、（如果是異機克隆） 將ZIP檔案複製到目標計算機的相應目錄。 
4、 解壓 tar 包
# tar zxvf db_1.bak -C /app/oracle/product/11.2.0/
注意：
如果有多個節點則所有節點重複2、3、4步驟 。

5、 清除$ORACLE_HOME/network/admin下的*.ora
6、 跑 $ORACLE_HOME/perl/bin/perl clone.pl 指令碼
node1-> $ORACLE_HOME/perl/bin/perl clone.pl ORACLE_BASE="/u01/app/oracle/" ORACLE_HOME="/app/oracle/product/11.2.0/db_1" OSDBA_GROUP=dba OSOPER_GROUP=oper -defaultHomeName
./runInstaller -clone -waitForCompletion "ORACLE_BASE=/u01/app/oracle/" "ORACLE_HOME=/app/oracle/product/11.2.0/db_1" "oracle_install_OSDBA=dba" "oracle_install_OSOPER=oper" -defaultHomeName -defaultHomeName -silent -noConfig -nowait

-- 含義：
Use the following syntax:
$ORACLE_HOME/perl/bin/perl clone.pl ORACLE_BASE="target_oracle_base" ORACLE_HOME="target_oracle_home"
OSDBA_GROUP=OSDBA_privileged_group OSOPER_GROUP=OSOPER_privileged_group -defaultHomeName

補充：
Oracle Universal Installer starts, and then records the cloning actions in the cloneActionstimestamp.log file. This log file is typically located in /orainventory_location/logs directory.

7、 重建監聽與dbca建庫
To configure the connection information for the new database, run Net Configuration Assistant:

$ cd $ORACLE_HOME/bin
$ ./netca
To create a new database for the newly cloned Oracle home, run Database Configuration Assistant:

$ cd $ORACLE_HOME/bin
$ ./dbca
