ORACLE 11g dataguard配置練習

兩臺伺服器資訊如下



 

主資料庫 10.1.1.21

安裝資料庫軟體、建立資料庫

 

standby資料庫10.1.1.23

 

 

準備工作

1、主資料庫啟用歸檔，經檢查已經啟用



 

2、standby資料庫上面安裝oracle 11g資料庫軟體，無需建立資料庫例項

 

3、standby上面建立必要的目錄，並賦予許可權

[oracle@standby ~]$ mkdir -p /home/oracle/app/oracle/admin/sap/adump

[oracle@standby ~]$ mkdir -p /home/oracle/app/oracle/oradata/sap/

[oracle@standby ~]$ mkdir -p /home/oracle/app/oracle/flash_recovery_area/sap/

[oracle@standby ~]$ mkdir -p /home/oracle/app/oracle/admin/standby/adump

 

 

4、在備用資料庫上面配置啟用監聽器

主資料庫配置檔案如下

 

[oracle@standby admin]$ cat listener.ora

# listener.ora Network Configuration File: /home/oracle/app/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora

# Generated by Oracle configuration tools.

SID_LIST_LISTENER =

(SID_LIST =

(SID_DESC =

(GLOBAL_DBNAME = standby)

(ORACLE_HOME = /home/oracle/app/oracle/product/11.2.0/dbhome_1)

(SID_NAME = standby)

)

)

LISTENER =

(DESCRIPTION_LIST =

(DESCRIPTION =

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

)

)

ADR_BASE_LISTENER = /home/oracle/app/oracle

 

備用資料庫listener配置如下

[oracle@standby admin]$ cat listener.ora

# listener.ora Network Configuration File: /home/oracle/app/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora

# Generated by Oracle configuration tools.

SID_LIST_LISTENER =

(SID_LIST =

(SID_DESC =

(GLOBAL_DBNAME = standby)

(ORACLE_HOME = /home/oracle/app/oracle/product/11.2.0/dbhome_1)

(SID_NAME = standby)

)

)

LISTENER =

(DESCRIPTION_LIST =

(DESCRIPTION =

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

)

)

ADR_BASE_LISTENER = /home/oracle/app/oracle

 

 

5、為每個系統配置tnsnames檔案

配置如下

[oracle@sap admin]$ cat tnsnames.ora

# tnsnames.ora Network Configuration File: /home/oracle/app/oracle/product/11.2.0/dbhome_1/network/admin/tnsnames.ora

# Generated by Oracle configuration tools.

SAP =

(DESCRIPTION =

(ADDRESS_LIST =

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

)

(CONNECT_DATA =

(SERVICE_NAME = sap)

)

)

STANDBY =

(DESCRIPTION =

(ADDRESS_LIST =

(ADDRESS = (PROTOCOL = TCP)(HOST = 10.1.1.23)(PORT = 1521))

)

(CONNECT_DATA =

(SERVICE_NAME = standby)

)

)

使用tnsping測試

在主資料庫上

[oracle@sap admin]$ tnsping sap

TNS Ping Utility for Linux: Version 11.2.0.1.0 - Production on 12-SEP-2014 21:50:22

Used parameter files:

/home/oracle/app/oracle/product/11.2.0/dbhome_1/network/admin/sqlnet.ora

Used TNSNAMES adapter to resolve the alias

Attempting to contact (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = sap)(PORT = 1521))) (CONNECT_DATA = (SERVICE_NAME = sap)))

OK (10 msec)

[oracle@sap admin]$ tnsping standby

TNS Ping Utility for Linux: Version 11.2.0.1.0 - Production on 12-SEP-2014 21:50:28

Attempting to contact (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 10.1.1.23)(PORT = 1521))) (CONNECT_DATA = (SERVICE_NAME = standby)))

OK (10 msec)

 

 

在standby資料庫上面

[oracle@standby bin]$ tnsping sap

TNS Ping Utility for Linux: Version 11.2.0.1.0 - Production on 12-SEP-2014 22:00:43

OK (10 msec)

[oracle@standby bin]$ tnsping standby

TNS Ping Utility for Linux: Version 11.2.0.1.0 - Production on 12-SEP-2014 22:00:49

OK (0 msec)

[oracle@standby bin]$

 

 

配置standby資料庫

1、建立引數檔案

[oracle@standby dbs]$ echo 'DB_NAME=standby' > ./initstandby.ora

[oracle@standby dbs]$ cat ./initstandby.ora

DB_NAME=standby

 

2、建立密碼檔案

將主資料庫的密碼檔案scp到standby資料庫響應目錄

 

3、啟動standby資料庫到nomount

[oracle@standby dbs]$ sqlplus / as sysdba

SQL*Plus: Release 11.2.0.1.0 Production on Fri Sep 12 22:55:13 2014

配置primary資料庫

 

1、建立standby logfile

SQL> alter database add standby logfile '/home/oracle/app/oracle/oradata/sap/standby01.log' size 50m;

Database altered.

SQL> alter database add standby logfile '/home/oracle/app/oracle/oradata/sap/standby02.log' size 50m;

Database altered.

Database altered.

SQL> alter database add standby logfile '/home/oracle/app/oracle/oradata/sap/standby04.log' size 50m;

Database altered.

SQL>

 

2、rman duplicate 建立備用資料庫

使用rman連線兩個資料庫

[oracle@sap admin]$ rman target / auxiliary sys/sys@standby

Recovery Manager: Release 11.2.0.1.0 - Production on Fri Sep 12 23:29:40 2014

Copyright (c) 1982, 2009, Oracle and/or its affiliates. All rights reserved.

執行duplicate使用以下指令碼

run{

配置data guard

1、將備用和主角色新增到standby資料庫

SQL> alter system set fal_server = sap;

System altered.

SQL> alter system set fal_client=standby;

System altered.

SQL> alter system set log_archive_config='dg_config=(sap,standby)';

System altered.

SQL> alter system set standby_file_management=auto;

System altered.

SQL> alter system set log_archive_dest_2='service=sap async db_unique_name=sap valid_for=(primary_role,online_logfile)';

System altered.

 

 

2、在standby資料庫上啟動log應用程式

SQL> alter database recover managed standby database using current logfile disconnect;

Database altered.

 

 

3、返回主資料庫，配置重做傳輸

SQL>

SQL> alter system set log_archive_config='dg_config=(sap,standby)';

System altered.

SQL>

SQL> alter system set log_archive_dest_2='service=standby async db_unique_name=standby valid_for=(primary_role,online_logfile)';

System altered.

SQL> alter system switch logfile;

System altered.

SQL> alter system set fal_server = standby;

System altered.

SQL> alter system set fal_client=sap;

System altered.

SQL> alter system set standby_file_management=auto;

System altered.

 

至此配置完成。

 

 

dataguard啟動停止步驟

停止過程

1、standby資料庫上停止redo日誌應用

alter database recover managed standby database cancel;

2、關閉之資料庫

3、關閉standby資料庫

 

啟動過程

1、啟動standby資料庫

2、啟動主資料庫

3、standby資料庫上執行redo日誌應用

alter database recover managed standby database using current logfile disconnect from session;
