[Oracle] Setup DataGuard

Oracle一步步搭建DataGuard

DataGuard环境:

  OS: SuSe 10

  Primary DB:

  	IP address:1.1.1.1

  	user:root

  	passwd:******

  	Oracle_SID:TEST

  	DB_UNIQUE_NAME:TEST_PD

  Standby DB:

  	IP address:2.2.2.2

  	user:root

  	passwd:******

  	Oracle_SID:TEST

  	DB_UNIQUE_NAME:TEST_ST

Primary端的配置

Primary db设置force logging模式

SQL> select force_logging from v$database;

FOR

---

YES

如果非force Logging模式, 则如下设置

SQL> alter database force logging;

Primary db设置归档模式

 SQL> archive log list;		

 Database log mode              Archive Mode

 Automatic archival             Enabled

 Archive destination            /data/u/arch/

 Oldest online log sequence     64

 Next log sequence to archive   66

 Current log sequence           66

如果非归档, 则如下设置

 SQL> shutdown immediate

 SQL> startup mount

 SQL> alter database archivelog;

 SQL> alter database open;

创建Standy口令文件

 oracle@test_mem_issue:~> orapwd file='/u/rman/orapwTEST' password=test123 entries=10

scp口令文件到standby对应的位置:

 oracle@test_mem_issue:~> scp /u/rman/orapwdTEST oracle@2.2.2.2#36000:<$ORACLE_HOME>/dbs

<$ORACLE_HOME>: oracle软件目录 /u/ora11g/product/11.2.0/db_1

修改初始化参数文件

pfile默认的位置在$ORACLE_HOME/dbs目录下, 当然也可以自己执行:

 SQL> create pfile from spfile;

在initTEST.ora中添加一下内容:

 *.DB_UNIQUE_NAME='TEST_PD'

 *.log_archive_dest_1='location=/u/arch VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=TEST_PD'

 *.log_archive_dest_2='SERVICE=STANDBY lgwr async VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=TEST_ST'

 *.LOG_ARCHIVE_DEST_STATE_1=ENABLE

 *.LOG_ARCHIVE_DEST_STATE_2=ENABLE

 *.standby_file_management='AUTO'

 *.FAL_SERVER='STANDBY'

 *.FAL_CLIENT='PRIMARY'

 *.log_archive_config='DG_CONFIG=(TEST_PD,TEST_ST)'

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

 *.ARCHIVE_LAG_TARGET=900

如果Primary和standby的数据文件位置不同, 还需要加如下2个参数:

 *.log_file_name_convert='/u/oradata/TEST/','/u/oradata1/TEST/'

 *.db_file_name_convert='/u/oradata/TEST/','/u/oradata1/TEST/'

--注意:

 *.FAL_SERVER='STANDBY'

 *.FAL_CLIENT='PRIMARY'

STANDBY,PRIMARY是tnsname.ora文件中配置的描述符

用刚修改过的pfile启动primary db,并生成spfile.

 SQL> shutdown immediate

 Database closed.

 Database dismounted.

 ORACLE instance shut down.

 SQL> startup pfile='/u/ora11g/product/11.2.0/db_1/dbs/initTEST.ora';

 ORACLE instance started.

 Total System Global Area 1603411968 bytes

 Fixed Size                  2226912 bytes

 Variable Size             486540576 bytes

 Database Buffers         1107296256 bytes

 Redo Buffers                7348224 bytes

 Database mounted.

 Database opened.

 SQL> create spfile from pfile='/u/ora11g/product/11.2.0/db_1/dbs/initTEST.ora';

 File created.

修改listener.ora和tnsnams.ora文件

Listener.ora文件

 LISTENER =

   (DESCRIPTION_LIST =

 	(DESCRIPTION =

 	  (ADDRESS = (PROTOCOL = TCP)(HOST = 1.1.1.1)(PORT = 1521))

 	)

   )

 	(SID_DESC =

 	  (ORACLE_HOME = /u/ora11g/product/11.2.0/db_1)

 	  (SID_NAME = TEST)

 	)

   )

Tnsnames.ora文件

 STANDBY =

   (DESCRIPTION =

 	(ADDRESS = (PROTOCOL = TCP)(HOST = 2.2.2.2)(PORT = 1521))

 	(CONNECT_DATA =

 	  (SERVER = DEDICATED)

 	  (SERVICE_NAME = TEST)

 	)

   )

 PRIMARY =

   (DESCRIPTION =

 	(ADDRESS = (PROTOCOL = TCP)(HOST = 1.1.1.1)(PORT = 1521))

 	(CONNECT_DATA =

 	  (SERVER = DEDICATED)

 	  (SERVICE_NAME = TEST)

 	)

   )

查看监听状态.

添加standby redolog files

DataGuard启动

--注意:DataGuard的启动顺序

启动顺序: 先standby后primary

关闭顺序: 先primary后standby

(1). 在standby db上执行

SQL> select open_mode from v$database;

OPEN_MODE

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

MOUNTED

SQL> alter database open read only;

Database altered.

--注意:

如果没有处理前面recover的报错(找不到归档日志), 这里可能启动的时候报system表空间和控制文件记录的内容出现不一致, 这个时候最好的方法就是, 去主库拷贝那些丢失的归档.

SQL> alter database open read only;

alter database open read only

*

ERROR at line 1:

ORA-10458: standby database requires recovery

ORA-01152: file 1 was not restored from a sufficiently old backup

ORA-01110: data file 1: '/u/ora11g/oradata/TEST/system01.dbf'

之前recover的时候注意到,有ORA提示到归档日志有缺失.

再次以read only方式启动standby db就可以了.

SQL> alter database open read only;

Database altered.

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

Database altered.

(2).在primay db上检查如下参数,如果没有则设置.

SQL> alter system set log_archive_dest_2='SERVICE=STANDBY ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=TEST_ST';

System altered.

SQL> alter system set log_archive_dest_state_2=ENABLE;

System altered.

SQL> alter system set archive_lag_target=900;

System altered.

(3).查询是否有出错信息(primary和standby上均执行下)

primary上执行:

SQL> select dest_id,status,destination,error from v$archive_dest where dest_id<=5;

   DEST_ID STATUS    DESTINATIO ERROR

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

         1 VALID     /u/arch

         2 VALID     STANDBY

         3 INACTIVE

         4 INACTIVE

         5 INACTIVE

standby上执行:

SQL> select dest_id,status,destination,error from v$archive_dest where dest_id<=5;

   DEST_ID STATUS    DESTINATIO ERROR

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

         1 VALID     /u/arch

         2 VALID     PRIMARY

         3 INACTIVE

         4 INACTIVE

         5 INACTIVE

验证DataGuard：

(1).在standby查看

SQL> select sequence#,first_time,next_time from v$archived_log order by sequence#;

 SEQUENCE# FIRST_TIME          NEXT_TIME

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

        68 07/09/2013 11:54:31 07/09/2013 12:09:31

        68 07/09/2013 09:49:35 07/09/2013 10:04:35

        68 07/09/2013 11:54:31 07/09/2013 12:09:31

        91 07/09/2013 14:56:01 07/09/2013 15:11:00

        92 07/09/2013 15:11:00 07/09/2013 15:19:42

        93 07/09/2013 15:19:42 07/09/2013 15:34:42

28 rows selected.

(2).在primary上执行归档命令并查看已归档的日志

SQL> alter system archive log current;

System altered.

SQL> select sequence#,first_time,next_time from v$archived_log order by sequence#;

 SEQUENCE# FIRST_TIME          NEXT_TIME

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

        62 09/25/2010 03:20:17 07/08/2013 21:10:42

        63 07/08/2013 21:10:42 07/08/2013 21:10:45

        64 07/08/2013 21:10:45 07/08/2013 21:10:47

		......

        93 07/09/2013 15:19:42 07/09/2013 15:34:42

        94 07/09/2013 15:34:42 07/09/2013 15:40:44

        94 07/09/2013 15:34:42 07/09/2013 15:40:44

61 rows selected.

(3).再次在standby上看当前已归档的日志

SQL> select sequence#,first_time,next_time from v$archived_log order by sequence#;

 SEQUENCE# FIRST_TIME          NEXT_TIME

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

        68 07/09/2013 11:54:31 07/09/2013 12:09:31

        68 07/09/2013 09:49:35 07/09/2013 10:04:35

        68 07/09/2013 11:54:31 07/09/2013 12:09:31

        ......

        91 07/09/2013 14:56:01 07/09/2013 15:11:00

        92 07/09/2013 15:11:00 07/09/2013 15:19:42

        93 07/09/2013 15:19:42 07/09/2013 15:34:42

        94 07/09/2013 15:34:42 07/09/2013 15:40:44

29 rows selected.

另外, 同样可以从alert文件里也看到了94号日志应用.

$ tail -f alert_TEST.log
