[20170206]关于Data Guard Gap Detection and Resolution2.txt
--测试看看一些参数不设置是否可以解决gap问题.
1.环境:
SYS@book> @ &r/ver1
PORT_STRING VERSION BANNER
------------------------------ -------------- --------------------------------------------------------------------------------
x86_64/Linux 2.4.xx 11.2.0.4.0 Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64bit Production
--//节前花了一个上午安装一台dg,我一般安装dataguard,自己有一个标准的文档,dataguard实例名我一般选择主库实例名后面加dg
--//[注:如果长于8个字符,选择d1,d2.]
--//为了测试方便,使用文本参数文件,这样测试方便一些.
SYS@book> create pfile='/tmp/book.ora' from spfile ;
File created.
2.说明我一般修改如下参数:
--主库:
*.log_archive_config='DG_CONFIG=(book,bookdg)'
*.fal_client='book'
*.fal_server='bookdg'
*.standby_file_management='auto'
*.log_archive_dest_1='LOCATION=/u01/app/oracle/archivelog/book MANDATORY VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=book'
*.log_archive_dest_2='SERVICE=bookdg LGWR ASYNC AFFIRM VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=bookdg'
*.db_file_name_convert='/mnt/ramdisk/book','/mnt/ramdisk/book'
*.log_file_name_convert='/mnt/ramdisk/book','/mnt/ramdisk/book'
*.db_unique_name='BOOK'
--备库:
*.log_archive_config='DG_CONFIG=(book,bookdg)'
*.fal_client='bookdg'
*.fal_server='book'
*.standby_file_management='auto'
*.log_archive_dest_1='LOCATION=/u01/app/oracle/archivelog/book MANDATORY VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=bookdg'
*.log_archive_dest_2='SERVICE=book LGWR ASYNC AFFIRM VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=book'
*.db_file_name_convert='mnt/ramdisk/book','/mnt/ramdisk/book'
*.log_file_name_convert='/mnt/ramdisk/book','/mnt/ramdisk/book'
*.db_unique_name='bookdg'
*.service_names='book'
--//注:备库我一般service_names设置跟主库一样.
3.测试前修改参数文件参数:
--主库:
#*.log_archive_config='DG_CONFIG=(book,bookdg)'
#*.fal_client='book'
#*.fal_server='bookdg'
*.standby_file_management='auto'
#*.log_archive_dest_1='LOCATION=/u01/app/oracle/archivelog/book MANDATORY VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=book'
#*.log_archive_dest_2='SERVICE=bookdg LGWR ASYNC AFFIRM VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=bookdg'
*.log_archive_dest_1='LOCATION=/u01/app/oracle/archivelog/book MANDATORY VALID_FOR=(ALL_LOGFILES,ALL_ROLES)'
*.log_archive_dest_2='SERVICE=bookdg LGWR ASYNC AFFIRM VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE)'
*.db_file_name_convert='/mnt/ramdisk/book','/mnt/ramdisk/book'
*.log_file_name_convert='/mnt/ramdisk/book','/mnt/ramdisk/book'
#*.db_unique_name='BOOK'
--//注:取消fal_client,fal_server,log_archive_config,db_unique_name设置,并且log_archive_dest_N取消后面的DB_UNIQUE_NAME=XXX.
--备库:
#*.log_archive_config='DG_CONFIG=(book,bookdg)'
#*.fal_client='bookdg'
#*.fal_server='book'
*.standby_file_management='auto'
#*.log_archive_dest_1='LOCATION=/u01/app/oracle/archivelog/book MANDATORY VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=bookdg'
#*.log_archive_dest_2='SERVICE=book LGWR ASYNC AFFIRM VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=book'
*.log_archive_dest_1='LOCATION=/u01/app/oracle/archivelog/book MANDATORY VALID_FOR=(ALL_LOGFILES,ALL_ROLES)'
*.log_archive_dest_2='SERVICE=book LGWR ASYNC AFFIRM VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE)'
*.db_file_name_convert='mnt/ramdisk/book','/mnt/ramdisk/book'
*.log_file_name_convert='/mnt/ramdisk/book','/mnt/ramdisk/book'
#*.db_unique_name='bookdg'
*.service_names='book'
4.测试:
A.关闭2边数据库.使用对应文本参数文件启动看看.
B.先启动主库:

--总结:
--通过测试说明不设置fal_client,fal_server,log_archive_config,db_unique_name.也可以解决archivelog gap问题.虽然我个人不喜欢这种设置,尤其是db_unique_name一样.
--补充采用fal参数,alert文件的记录:
Set as converted control file due to db_unique_name mismatch
Changing di2dbun from book to bookdg
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~=> db_unique_name被修改回来了.
