說明

資料庫為 12.2.0.1.0RAC 環境，目標升級為 12.2.0.1.11 環境，作業系統為 RHEL6.6 ，

原環境：

資料庫模式

RAC

IP 地址分配

32BIT/64BIT

64 bit

作業系統版本

RHEL5.3

ORACLE 版本

12.2.0.1

ORACLE_SID

 

目標環境：

資料庫模式

RAC

IP 地址分配

32BIT/64BIT

64 bit

作業系統版本

RHEL6.6

ORACLE 版本

12.2.0.1

ORACLE_SID

 


前期輔助例項安裝

前提：裝好資料庫軟體，不建立資料庫，且有 oracle 使用者，首先建立輔助例項

為輔助例項建立密碼檔案

直接從原生產複製密碼檔案至複製庫端

 

建立必要的目錄

[oracle@node2 admin]$ mkdir -p /oracle/app/admin/ora11g/adump

[oracle@node2 admin]$ mkdir -p /oracle/app/oradata/ora11g/

 

配置靜態監聽

[oracle@node2 admin]$ vi listener.ora

 

        (GLOBAL_DBNAME = woo.com)

# listener.ora Network Configuration File: /oracle/app/product/11.2.0/db_1/network/admin/listener.ora

# Generated by Oracle configuration tools.

 

LISTENER =

  (DESCRIPTION_LIST =

    (DESCRIPTION =

      (ADDRESS = (PROTOCOL = TCP)(HOST = jason)(PORT = 1521))

      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))

    )

  )

SID_LIST_LISTENER =

(SID_LIST =

  (SID_DESC =

    (SID_NAME = orcl)

    (ORACLE_HOME = /oracle/app/product/12.2.0/db_1)

    (GLOBAL_DBNAME = orcl)

  )

)

 

配置所有節點 tnsname 資訊如下 :

ORCL =

  (DESCRIPTION =

    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.210.69)(PORT = 1521))

    (CONNECT_DATA =

      (SERVER = DEDICATED)

      (SERVICE_NAME = orcl)

    )

  )

orcldg =

  (DESCRIPTION =

    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.210.96)(PORT = 1521))

    (CONNECT_DATA =

      (SERVER = DEDICATED)

      (SERVICE_NAME = orcl)

    )

  )

建立輔助例項的初始化引數檔案

將在原生產上建立的 pfile 複製到複製庫，引數和原生產庫保持一致，並啟動到 nomount 狀態

 

生產端產生 pfile

 

SQL> create pfile='/tmp/upgrade/initora11g.ora' from spfile;

 

File created.

將引數檔案複製到複製庫相應位置

 

啟動資料庫到 nomount 狀態

[oracle@node2 ~]$ sqlplus / as sysdba

複製資料庫

同時連線到目標庫和複製庫

[oracle@node2 ~]$ rman target sys/oracle@orcl auxiliary sys/oracle@orcldg
