物理DATAGUARD最大性能模式配置过程

主库主机edbjr2p1

备库主机edbjr2p2

1.创建主库

[root@edbjr2p1 ~]# xhost +

access control disabled, clients can connect from any host

[root@edbjr2p1 ~]# su - oracle

[oracle@edbjr2p1 ~]$ dbca

建库过程略。。。ORACLE_SID=ORCL

2.主库参数

[oracle@edbjr2p1 ~]$ export ORACLE_SID=ORCL

[oracle@edbjr2p1 ~]$ sqlplus / as sysdba

SYS@ORCL>

SYS@ORCL>alter database archivelog;

Database altered.

SYS@ORCL>alter system set log_archive_config='dg_config=(orcl,aux1)';

System altered.

SYS@ORCL>alter system set log_archive_dest_10='location=/home/oracle/orcl_arclog valid_for=(online_logfiles,all_roles) db_unique_name=orcl';

System altered.

SYS@ORCL>

创建目录用于存放归档

[oracle@edbjr2p1 admin]$ mkdir /home/oracle/orcl_arclog

继续更改参数

SYS@ORCL>alter system set log_archive_dest_1='service=aux1 valid_for=(online_logfiles,primary_role) db_unique_name=aux1';

System altered.

SYS@ORCL>alter system set log_archive_max_processes=4;

System altered.

SYS@ORCL>create pfile from spfile;

File created.

传输pfile文件和密码文件

[oracle@edbjr2p1 admin]$ scp $ORACLE_HOME/dbs/initORCL.ora edbjr2p2:$ORACLE_HOME/dbs/initAUX1.ora

oracle@edbjr2p2's password:

initORCL.ora 100% 1178 1.2KB/s 00:00

[oracle@edbjr2p1 admin]$ scp $ORACLE_HOME/dbs/orapwORCL edbjr2p2:$ORACLE_HOME/dbs/orapwAUX1

oracle@edbjr2p2's password:

orapwORCL 100% 1536 1.5KB/s 00:00

[oracle@edbjr2p1 admin]$

3.在备库中修改传输过来的pfile文件

[root@edbjr2p2 ~]# su - oracle

[oracle@edbjr2p2 ~]$ cd $ORACLE_HOME/dbs

[oracle@edbjr2p2 dbs]$ ls

initAUX1.ora initdw.ora init.ora orapwAUX1

[oracle@edbjr2p2 dbs]$ vi initAUX1.ora

以下是在文件中修改的

*.audit_file_dest='/u01/app/oracle/admin/AUX1/adump'

*.background_dump_dest='/u01/app/oracle/admin/AUX1/bdump'

*.control_files='/u01/app/oracle/oradata/AUX1/control01.ctl','/u01/app/oracle/oradata/AUX1/control02.ctl','/u01/app/oracle/oradata/AUX1/control03.ctl'

*.core_dump_dest='/u01/app/oracle/admin/AUX1/cdump'

*.log_archive_dest_10='location=/home/oracle/aux1_arclog valid_for=(online_logfiles,all_roles) db_unique_name=aux1'

*.user_dump_dest='/u01/app/oracle/admin/AUX1/udump'

以下是在文件中添加的

*.db_unique_name='AUX1'

*.standby_archive_dest='/home/oracle/aux1_stdlog'

*.db_file_name_convert=('/u01/app/oracle/oradata/ORCL/','/u01/app/oracle/oradata/AUX1/')

*.log_file_name_convert=('/u01/app/oracle/oradata/ORCL/','/u01/app/oracle/oradata/AUX1/')

*.standby_file_management='auto'

在备库中创建目录
