  1. 搭建环境：
  2. OS：Solaris10 x86-64
  3. DB：Oracle 11.2.0
  4. 主库所在主机：sol01
  5. 备库所在主机：sol02
  7. 2 主库部署步骤
  8. 2.1 主库操作
  9. 创建归档目录，开启归档模式。
  10. su – oracle
  11. mkdir /orahome/oracle/archivelog
  12. sqlplus /as sysdba
  13. shutdown immediate
  14. startup mount
  16. alter database archivelog;
  18. 查看是否force_logging模式
  19. SQL> select log_mode,force_logging from v$database;
  20. 开启force_logging模式
  21. alter database force logging;
  23. create pfile from spfile;
  25. 创建备库控制文件
  26. alter database create standby controlfile as '/orahome/oracle/bak/controlfile01.ctl';
  28. 创建备库日志组路径
  29. alter database add standby logfile group 4 '/orahome/oracle/app/oradata/test/standbyredo04.log' size 50m;
  30. alter database add standby logfile group 5 '/orahome/oracle/app/oradata/test/standbyredo05.log' size 50m;
  31. alter database add standby logfile group 6 '/orahome/oracle/app/oradata/test/standbyredo06.log' size 50m;
  32. alter database add standby logfile group 7 '/orahome/oracle/app/oradata/test/standbyredo07.log' size 50m;
  34. cd $ORACLE_HOME/dbs
  35. 备份参数文件
  36. cp inittest.ora  inittest.ora.bk
  37. 2.2 在inittest.ora参数文件中加入：
  38. 修改参数文件：
  39. db_unique_name=test
  40. log_archive_config='dg_config=(test,test_dg)'
  41. log_archive_dest_1='location=/orahome/oracle/archivelog valid_for=(all_logfiles,all_roles) db_unique_name=test'
  42. log_archive_dest_2='service=test_dg lgwr async valid_for=(online_logfiles,primary_role) db_unique_name=test_dg'
  43. log_archive_dest_state_1=enable
  44. log_archive_dest_state_2=enable
  45. fal_server=test_dg
  46. fal_client=test
  47. db_file_name_convert='/orahome/oracle/app/oradata/test','/orahome/oracle/app/oradata/test'
  48. log_file_name_convert='/orahome/oracle/app/oradata/test','/orahome/oracle/app/oradata/test'
  49. standby_file_management=auto
  51. 2.3 使更改参数生效：
  52. sqlplus / as sysdba
  53. startup nomount pfile= '$ORACLE_HOME/dbs/inittest.ora';
  54. create spfile from pfile;
  55. shutdown immediate
  56. startup mount
  59. 2.4 把相应的文件SCP到standby主机：
  60. 控制文件：
  61. scp /orahome/oracle/bak/controlfile01.ctl 192.168.0.22: $ORACLE_BASE/oradata/$ORACLE_SID/control01.ctl
  62. scp /orahome/oracle/bak/controlfile01.ctl 192.168.0.22: $ORACLE_BASE/oradata/$ORACLE_SID/control02.ctl
  63. oracle口令文件：
  64. scp orapwgisdb1 192.168.111.129:/home/oracle/u01/11.2.3/dbhome_1/dbs/orapwgisdb2
  65. oracle数据文件：
  66. scp $ORACLE_BASE/oradata/$ORACLE_SID/*.dbf 192.168.0.22:$ORACLE_BASE/oradata/$ORACLE_SID/
  67. oracle redo日志文件（不包括standyredo.log）
  68. scp $ORACLE_BASE/oradata/$ORACLE_SID/*.log 192.168.0.22:$ORACLE_BASE/oradata/$ORACLE_SID/
  69. 参数文件
  70. scp $ORACLE_HOME/dbs/inittest.ora 192.168.0.22:$ORACLE_HOME/dbs/
  71. 2.5 更改备库使用的pfile:inittest.ora
  72. db_unique_name=test_dg
  73. log_archive_config='dg_config=(test,test_dg)'
  74. log_archive_dest_1='location=/orahome/oracle/archivelog valid_for=(all_logfiles,all_roles) db_unique_name=test_dg'
  75. log_archive_dest_2='service=test lgwr async valid_for=(online_logfiles,primary_role) db_unique_name=test'
  76. log_archive_dest_state_1=enable
  77. log_archive_dest_state_2=enable
  78. fal_server=test
  79. fal_client=test_dg
  80. db_file_name_convert='/orahome/oracle/app/oradata/test','/orahome/oracle/app/oradata/test'
  81. log_file_name_convert='/orahome/oracle/app/oradata/test','/orahome/oracle/app/oradata/test'
  82. standby_file_management=auto
  83. 2.6 配置监听：
  84.  bash-3.00$ more tnsnames.ora
  85. test =
  87.   (DESCRIPTION =
  89.     (ADDRESS_LIST =
  91.       (ADDRESS = (PROTOCOL = TCP)(HOST =192.168.0.21 )(PORT = 1521))
  93.     )
  95.     (CONNECT_DATA =
  97.       (SERVICE_NAME = test)
  99.     )
  101.   )
  103. test_dg =
  105.   (DESCRIPTION =
  107.     (ADDRESS_LIST =
  109.       (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.22)(PORT = 1521))
  111.     )
  113.     (CONNECT_DATA =
  115.       (SERVICE_NAME = test_dg)
  117.     )
  119.   )
  120. 将tnsnames.ora文件拷贝到备库相同位置。
  121. 2.7 打开主库：
  123. Alter database open;
  124. 日志如下：
  127. 3 从库上操作：
  128. 3.1 创建需要的目录
  129. mkdir -p $ORACLE_BASE/oradata/test
  130. mkdir -p $ORACLE_BASE/admin/test/{a,dp}dump
  131. sqlplus / as sysdba
  132. startup nomount pfile='$ORACLE_HOME/dbs/inittest.ora';
  133. create spfile from pfile;
  134. startup nomount
  137. 3.2 配置网络服务
  138. 启动监听(lsnrctl start),再tnsnames.ora中加入如下内容
  139. bash-3.00$ more tnsnames.ora
  140. test =
  142.   (DESCRIPTION =
  144.     (ADDRESS_LIST =
  146.       (ADDRESS = (PROTOCOL = TCP)(HOST =192.168.0.21 )(PORT = 1521))
  148.     )
  150.     (CONNECT_DATA =
  152.       (SERVICE_NAME = test)
  154.     )
  156.   )
  158. test_dg =
  160.   (DESCRIPTION =
  162.     (ADDRESS_LIST =
  164.       (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.22)(PORT = 1521))
  166.     )
  168.     (CONNECT_DATA =
  170.       (SERVICE_NAME = test_dg)
  172.     )
  174.   )
  176. 查看tnsping是否互通
  178. 将备库启动到mount状态
  179. alter database mount;
  181. 添加备库日志组
  182. alter database add standby logfile group 4 '/orahome/oracle/app/oradata/test/standbyredo04.log' size 50m;
  183. alter database add standby logfile group 5 '/orahome/oracle/app/oradata/test/standbyredo05.log' size 50m;
