Oracle 2套rac集群指向单机多实例的复制搭建

由于环境限制，现在需要把2套rac集群通过dg复制指向远端的单机多实例上面。

rac指向第一个实例的前面已经有文档

这里直接添加第二个实例的复制搭建，主要标出不同地方

单实例环境--standby CentOS release 6.10 (Final) hostname dg1 ip 10.*.30 Instance_name cad DB_NAME bol --此次2个一样 db_unique_name cad

SQL*Plus: Release 11.2.0.4.0 Production

文件系统规划 Primary Standby +DATA/bol/datafile/test01.dbf 　　 　　  /u01/app/Oracle/oradata/cad/data tempfile +data/bol/tempfile　　　　　　　　        /u01/app/oracle/oradata/cad/control01.ctl +fra/bol/archivelog　　　　　　　　      /u01/app/oracle/fast_recovery_area/cad +fra/bol/onlinelog 　　　　　　　　　　 /u01/app/oracle/oradata/orcl/cad

基本步骤与上面相同，只是实例名有不同之处

1 主库rac集群，设置为归档，和force logging模式

2 主库添加 standby Redo log 文件

3 主备库修改listener.ora 和tnsnames.ora 文件

主库与之前基本相同

备库

[oracle@dg1 admin]$ cat listener.ora # listener.ora Network Configuration File: /u01/app/oracle/product/11.2.0/db_1/network/admin/listener.ora # Generated by Oracle configuration tools.

SID_LIST_LISTENER =  (SID_LIST =  (SID_DESC =  (GLOBAL_DBNAME = orcl)  (ORACLE_HOME = /u01/app/oracle/product/11.2.0/db_1)  (SID_NAME = orcl)  )  (SID_DESC =  (GLOBAL_DBNAME = cad)  (ORACLE_HOME = /u01/app/oracle/product/11.2.0/db_1)  (SID_NAME = cad)  ---在主机dg1上 ，添加2个实例 )  )

LISTENER =  (DESCRIPTION_LIST =  (DESCRIPTION =  (ADDRESS = (PROTOCOL = TCP)(HOST = dg1)(PORT = 1521))  )  (DESCRIPTION =  (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))  )  )

ADR_BASE_LISTENER = /u01/app/oracle

[oracle@dg1 admin]$ cat tnsnames.ora bol=  (DESCRIPTION =  (ADDRESS = (PROTOCOL = TCP)(HOST = 10.*.15)(PORT = 1521))  (ADDRESS = (PROTOCOL = TCP)(HOST = 10.*.16)(PORT = 1521))  (CONNECT_DATA =  (SERVER = DEDICATED)  (SERVICE_NAME =bol)  )  )

orcl=  (DESCRIPTION =  (ADDRESS = (PROTOCOL = TCP)(HOST = 10.*.30)(PORT = 1521))  (CONNECT_DATA =  (SERVER = DEDICATED)  (SERVICE_NAME =orcl)  )  )

cad=  (DESCRIPTION =  (ADDRESS = (PROTOCOL = TCP)(HOST = 10.*.30)(PORT = 1521))  (CONNECT_DATA =  (SERVER = DEDICATED)  (SERVICE_NAME =cad)  )  ) [oracle@rac07 ~]$ tnsping cad

4 在备库创建相应的目录 mkdir -p /u01/app/oracle/fast_recovery_area/cad mkdir -p /u01/app/oracle/oradata/cad/data mkdir -p /u01/app/oracle/oradata/cad/tempfile mkdir -p /u01/app/oracle/admin/cad/adump mkdir -p /u01/app/oracle/admin/cad/data mkdir -p /u01/app/oracle/admin/cad/redo mkdir -p /u01/app/oracle/admin/cad/tempfile mkdir -p /u01/app/oracle/archive/cad

5 修改主备库参数和把主库密码文件cp到备库 --备库参数文件 cad.__db_cache_size=469762048 cad.__java_pool_size=16777216 cad.__large_pool_size=33554432 cad.__pga_aggregate_target=654311424 cad.__sga_target=956301312 cad.__shared_io_pool_size=0 cad.__shared_pool_size=385875968 cad.__streams_pool_size=33554432 *.audit_file_dest='/u01/app/oracle/admin/cad/adump' *.audit_trail='db' *.compatible='11.2.0.4.0' *.control_files='/u01/app/oracle/oradata/cad/control01.ctl','/u01/app/oracle/fast_recovery_area/cad/control02.ctl' *.db_block_size=8192 *.db_domain='' *.db_file_name_convert='+DATA/bol/datafile','/u01/app/oracle/oradata/cad/data','+DATA/bol/tempfile','/u01/app/oracle/oradata/cad/tempfile' *.db_name='bol' *.service_names='cad' *.db_unique_name='cad' *.db_recovery_file_dest='/u01/app/oracle/fast_recovery_area/cad' *.db_recovery_file_dest_size=6005194752 *.diagnostic_dest='/u01/app/oracle' *.dispatchers='(PROTOCOL=TCP) (SERVICE=bolXDB)' *.fal_server='cad' *.log_archive_config='dg_config=(bol,cad)' *.log_archive_dest_1='location=/u01/app/oracle/archive/cad valid_for=(all_logfiles,all_roles) db_unique_name=cad' *.log_archive_dest_2='service=bol valid_for=(online_logfiles,primary_role) db_unique_name=bol' *.log_archive_dest_state_1='ENABLE' *.log_archive_dest_state_2='ENABLE' *.log_archive_format='%t_%s_%r.arch' *.log_file_name_convert='+FRA/bol/onlinelog','/u01/app/oracle/admin/cad/redo' *.memory_target=1606418432 *.open_cursors=300 *.processes=500 *.remote_login_passwordfile='exclusive' *.standby_file_management='auto' *.undo_tablespace='UNDOTBS1'

6 使用 spfile 将备库启动 nomount 状态并启动监听

7 备库进行duplicate

export ORACLE_SID=cad rman target sys/****@10.*.29/bol auxiliary sys/****@cad nocatalog

8 开启dg复制
