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
