12102 Using the DUPLICATE Command to Create a Standby Database

1   描述

利用rman duplicate同一主机上创建standby database.

2   操作环境

OEL7.2

Oracle database 12.1.0.2.0

DB_NAME=S12102

3   过程设计

3.1  主库DG配置

3.2  操作系统用户DG环境配置

3.3  listener.ora与tnsnames.ora配置

3.4  rman duplicate

4   详细步骤操作

4.1  主库DG配置

shutdown immediate;

startup mount;

alter database archivelog;

alter database open;

create pfile from spfile;

ALTER DATABASE FORCE LOGGING;

ALTER DATABASE ADD STANDBY LOGFILE ('/u01/app/product/oradata/S12102/sredo01.log') SIZE 50M;

ALTER DATABASE ADD STANDBY LOGFILE ('/u01/app/product/oradata/S12102/sredo02.log') SIZE 50M;

ALTER DATABASE ADD STANDBY LOGFILE ('/u01/app/product/oradata/S12102/sredo03.log') SIZE 50M;

ALTER DATABASE ADD STANDBY LOGFILE ('/u01/app/product/oradata/S12102/sredo04.log') SIZE 50M;

--standby redo是在备库上work的，主库也可以添加,方便日后switchover改maxprotected模式时使用。添加在主库，在创建DataGuard时，备库自然也就有了，比较省事。-- The standby redo log must have at least one more redo log group than the redo log at the redo source database, for each redo thread at the redo source database. At the redo source database, query the V$LOG view to determine how many redo log groups are in the redo log at the redo source database and query the V$THREAD view to determine how many redo threads exist at the redo source database.

alter system set LOG_ARCHIVE_CONFIG='DG_CONFIG=(S12102,S12102D)';

alter system set LOG_ARCHIVE_DEST_1='LOCATION=USE_DB_RECOVERY_FILE_DEST  VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=S12102';

alter system set LOG_ARCHIVE_DEST_2='SERVICE=S12102D ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=S12102D' ;

alter system set FAL_SERVER=S12102D;

alter system set FAL_CLIENT=S12102;

alter system set STANDBY_FILE_MANAGEMENT=AUTO;

--此两项需要重启数据库生效

alter system set DB_FILE_NAME_CONVERT='/u01/app/product/oradata/S12102D/','/u01/app/product/oradata/S12102' scope=spfile;

alter system set LOG_FILE_NAME_CONVERT='/u01/app/product/oradata/S12102D/','/u01/app/product/oradata/S12102' scope=spfile;

4.2  操作系统用户DG环境配置

cd $ORACLE_HOME/dbs

cp initS12102.ora initS12102D.ora

cp orapwS12102 orapwS12102D

chmod 775 $TNS_ADMIN

编辑standby db参数文件,创建standby database目录，配置standby系统环境变量略

4.3  listener.ora与tnsnames.ora配置(本环境使用GRID监听)

[grid@localhost 12.1.0.2.0:(+ASM) network ] $ cat listener.ora

# listener.ora Network Configuration File: /u01/app/product/admin/network/listener.ora

    )

    )

    (CONNECT_DATA =

      (SERVICE_NAME = S12102)

    )

  )

4.4  rman duplicate

--备库启到nomount状态略

rman target sys/oracle@S12102 auxiliary sys/oracle@S12102D

startup clone nomount;

run{

duplicate target database for standby from active database nofilenamecheck

SPFILE

set control_files='/u01/app/product/oradata/S12102D/control01.ctl','/u01/app/product/fast_recovery_area/S12102D/control02.ctl'

set LOG_ARCHIVE_DEST_1='LOCATION=USE_DB_RECOVERY_FILE_DEST  VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=S12102D'

set LOG_ARCHIVE_DEST_2='SERVICE=S12102 ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=S12102'

set FAL_SERVER='S12102'

set FAL_CLIENT='S12102D'

set LOG_FILE_NAME_CONVERT='/u01/app/product/oradata/S12102','/u01/app/product/oradata/S12102D'

set STANDBY_FILE_MANAGEMENT='AUTO';

}

5   个人总结

当监听由gird用户启动时，注意$TNS_ADMIN目录权限应为775。
