Oracle12c rac-dg搭建

主库上的操作

1. 一、 开启RAC的forcelogging(已开)

SQL> alter database force logging;

2. 修改RAC初始化参数文件（根据实际情况修改）

SQL> alter system setlog_archive_config='DG_CONFIG=(eisoo,eisoos)';

SQL> alter system set log_archive_dest_2='SERVICE=eisoos ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE)DB_UNIQUE_NAME=eisoos' scope=spfile;

SQL> alter system setlog_archive_dest_state_1=ENABLE;

SQL> alter system set log_archive_dest_state_2=ENABLE;

SQL> alter system set fal_server=eisoos;

SQL> alter system setdb_file_name_convert='eisoos','eisoo' scope=spfile;

SQL> alter system set db_file_name_convert='/data/oradata/eisoos','+DATA/EISOO/DATAFILE'scope=spfile; //如果备库没有使用asm，红色为备库数据文件目录

SQL> alter system setlog_file_name_convert='eisoos','eisoo'scope=spfile;

SQL> alter system setlog_file_name_convert='/data/oradata/eisoos','+DATA/EISOO/ONLINELOG'scope=spfile;//如果备库没有使用asm

SQL> alter system set standby_file_management='AUTO';

SQL> alter system setlog_archive_max_processes=30;

注：红色字为备库相关信息

3. 开启归档模式（已做）

4. 创建standby logfile（先查看是否已创建）

查看是否有

selectgroup#,thread#,sequence#,archived,status from v$standby_log;

查看当前如日之大小

SQL> select thread#,group#,bytes/1024/1024/1024from v$log;

THREAD# GROUP# BYTES/1024/1024

---------- ---------- ---------------

1 1 50

1 2 50

2 3 50

2 4 50

新建多个和当前日志大小的standby logfile

SQL> alter database add standby logfilethread 2 group 4 size 4G;

SQL> alter database add standby logfilethread 2 group 5 size 4G;

SQL> alter database add standby logfilethread 2 group 6 size 4G;

SQL> alter database add standby logfilethread 2 group 7 size 4G;

SQL> alter database add standby logfilethread 2 group 8 size 50M;

SQL> alter database add standby logfilethread 2 group 9 size 50M;

SQL> selectthread#,group#,bytes/1024/1024 from v$standby_log;

THREAD# GROUP# BYTES/1024/1024

---------- ---------- ---------------

1 10 50

1 11 50

1 12 50

2 13 50

2 14 50

2 15 50

5. 创建备库参数文件

SQL> show parameter spfile;

NAME TYPE VALUE

----------------------------------------------- ------------------------------

spfile string +DATA/EISOO/PARAMETERFILE/spfile.281.923255053

SQL> create pfile='/tmp/initeisoos.ora'from spfile='+DATA/EISOO/PARAMETERFILE/spfile.281.923255053';

[oracle@rac1 tmp]$ scp initeisoos.ora192.168.180.48:$ORACLE_HOME/dbs

//将参数文件传至备库dbs目录下

备库上的操作

1. 修改参数文件

单机未使用asm：

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

*.audit_trail='db'

*.compatible='12.1.0.2.0'

*.control_files='/data/oradata/eisoos/control01.ctl'#RestoreControlfile

*.db_block_size=8192

*.db_create_file_dest='/data/oradata/eisoos'

*.db_domain=''

*.db_file_name_convert='+DATA/EISOO/DATAFILE','/data/oradata/eisoos','+DATA/EISOO/TEMPFILE','/data/oradata/eisoos'

*.db_name='eisoo'

*.db_unique_name='eisoos'

*.diagnostic_dest='/u01/app/oracle'

*.dispatchers='(PROTOCOL=TCP) (SERVICE=eisoosXDB)'

*.fal_server='EISOOS'

*.log_archive_config='DG_CONFIG=(eisoo,eisoos)'

*.log_archive_dest_1='LOCATION=/data/oradata/eisoos/archivelog'

*.log_archive_dest_2='SERVICE=eisoo ASYNCVALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=eisoo'

*.log_archive_dest_state_1='ENABLE'

*.log_archive_dest_state_2='ENABLE'

*.log_archive_format='%t_%s_%r.arc'

*.log_archive_max_processes=30

*.log_file_name_convert='+DATA/EISOO/ONLINELOG','/data/oradata/eisoos'

*.open_cursors=300

*.pga_aggregate_target=453m //需要根据实际情况修改

*.processes=300 //需要根据实际情况修改

*.remote_login_passwordfile='exclusive'

*.sga_target=1361m //需要根据实际情况修改

*.standby_file_management='AUTO'

eisoos.undo_tablespace='UNDOTBS1'

注：绿色字为主库相关信息

2. 启动到 nomout状态

SQL> startup nomount pfile='/u01/app/oracle/product/12.1.0/db_1/dbs/initeisoos.ora';

ORACLE instance started.

Total System Global Area 1442840576 bytes

Fixed Size 2924448 bytes

Variable Size 486539360 bytes

Database Buffers 939524096 bytes

Redo Buffers 13852672 bytes

SQL>

SQL>ALTER SYSTEM SETSEC_CASE_SENSITIVE_LOGON=false;

备注：SEC_CASE_SENSITIVE_LOGON参数是决定密码文件是否可以在本地创建，否则只能从主库拷贝到备库。默认值是“true”,

3. 在本地创建密码文件

创建和rac 的sys的密码相同的密码文件

ocrl:/u01/app/oracle/product/12.1.0/db_1/dbs@oracle1>orapwdfile=orapweisoos password=oracle entries=10 ignorecase=y force=y

4. 配置监听文件，保证primary和standby能够互连

备库:

LISTENER =

(DESCRIPTION_LIST =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.180.41)(PORT = 1521))

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))

)

)

SID_LIST_LISTENER =

(SID_LIST =

(SID_DESC =

(GLOBAL_DBNAME = eisoos)

(ORACLE_HOME = /u01/app/oracle/product/12.1.0/db_1)

(SID_NAME = eisoos)

)

)

主库和备库是tnsname.ora 配置如下：

eisoo =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.180.51)(PORT = 1521))

(CONNECT_DATA =

(SERVER = DEDICATED)

(SERVICE_NAME = eisoo)

)

)

eisoos =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.180.41)(PORT = 1521))

(CONNECT_DATA =

(SERVER = DEDICATED)

(SERVICE_NAME = eisoos)

)

)

主备分别验证：

[oracle@rac1 ~]$ sqlplus sys/oracle@eisooas sysdba

[oracle@rac1 ~]$ sqlplus sys/oracle@eisoosas sysdba

[oracle@rac2 ~]$ sqlplus sys/oracle@eisooas sysdba

[oracle@rac2 ~]$ sqlplus sys/oracle@eisoosas sysdba

5. 备份恢复数据

eisoos:/home/oracle@oracle1>rman targetsys/oracle@eisoo auxiliary sys/oracle@eisoos

connected to target database: EISOO(DBID=3774196505)

connected to auxiliary database: EISOO (notmounted)

RMAN> duplicate target database forstandby from active database;

Starting Duplicate Db at 2016/09/2616:52:12

6. 开启实时同步

SQL> alter database recover managedstandby database using current logfile disconnect from session;

验证:

1）

SQL> select dest_name,error fromv$archive_dest;//通过查看archive_log_dest_2列是否有error报错，如果有报错，则需要先根据报错内容解决问题

2）

查询主库最大归档序号和备库最大归档序号

select max(sequence#) from v$archived_log;

然后在主库切换日志：alter system switch logfile;

再次查询备库最大归档序号，一致即归档同步成功。

主库：

SQL> select max(sequence#) fromv$archived_log;

MAX(SEQUENCE#)

--------------

133

SQL> alter system switch logfile;

System altered.

SQL> select max(sequence#) fromv$archived_log;

MAX(SEQUENCE#)

--------------

134

SQL>

备库：

SQL> select max(sequence#) fromv$archived_log;

MAX(SEQUENCE#)

--------------

134

SQL>

3)

主库验证

SQL>select SEQUENCE#, FIRST_TIME,NEXT_TIME, APPLIED, ARCHIVED from V$ARCHIVED_LOG；

备库验证

SQL>select SEQUENCE#, FIRST_TIME,NEXT_TIME, APPLIED, ARCHIVED from V$ARCHIVED_LOG；

备注：观察主备库日志是否同步，如一致则表示日志CDP同步正常。

注意点：

如果sqlplus报用户名 密码错误，用orapw file=orapwORACLE,来创建密码文件
