[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$database; FOR --- YES如果非force Logging模式, 则如下设置
SQL> alter database force logging; -
Primary db设置归档模式
SQL> archive log list; Database log mode Archive Mode Automatic archival Enabled Archive destination /data/u/arch/ Oldest online log sequence 64 Next log sequence to archive 66 Current log sequence 66如果非归档, 则如下设置
SQL> shutdown immediate SQL> startup mount SQL> alter database archivelog; SQL> alter database open; -
创建Standy口令文件
oracle@test_mem_issue:~> orapwd file='/u/rman/orapwTEST' password=test123 entries=10scp口令文件到standby对应的位置:
oracle@test_mem_issue:~> scp /u/rman/orapwdTEST oracle@2.2.2.2#36000:<$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.

添加standby redolog files
standby redofile count=(online redofile + 1)*2 standby redofile size=online redofile size alter database add standby logfile group 34 ('/u/arch/TEST/stby/db_stb_redo04.log') size 50m; alter database add standby logfile group 33 ('/u/arch/TEST/stby/db_stb_redo03.log') size 50m; alter database add standby logfile group 32 ('/u/arch/TEST/stby/db_stb_redo02.log') size 50m; alter database add standby logfile group 31 ('/u/arch/TEST/stby/db_stb_redo01.log') size 50m; alter database add standby logfile group 30 ('/u/arch/TEST/stby/db_stb_redo10.log') size 50m; alter database add standby logfile group 39 ('/u/arch/TEST/stby/db_stb_redo09.log') size 50m; alter database add standby logfile group 38 ('/u/arch/TEST/stby/db_stb_redo08.log') size 50m; alter database add standby logfile group 37 ('/u/arch/TEST/stby/db_stb_redo07.log') size 50m; alter database add standby logfile group 36 ('/u/arch/TEST/stby/db_stb_redo06.log') size 50m; alter database add standby logfile group 35 ('/u/arch/TEST/stby/db_stb_redo05.log') size 50m; -
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; 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:

验证DataGuard：
(1).在standby查看
