日誌的 實時應用
要實現 日誌實時應用主要與 primary log_archive_dest_n='server= '
affirm,noaffirm（預設）
delay,nodelay（預設）
lgwr ,arcn*（預設）
lgwr中分sync ,async 預設（sync=parallel）
這幾個引數有關係
這幾個引數就關係著standby的 3個模式

lgwr裡面又分sync ,async net_timeout
sync ,async 是指定當設定lgwr後，日誌是同步傳輸還是非同步傳輸到standbylogfile;
注意lgwr必須需要建立standbylogfile;
重要的引數
主庫的log_archive_dest_n='service '決定很多重要
（一）預設是arcn 當主庫發生歸檔產生arch程式時候一個arcn程式主庫上本地歸檔同時另一個arcn程式（在主庫）傳給rfs程式 由rfs程式通過oraclenet 傳遞到standby庫 (rfs程式在standby)
當建立 standbylogfile 時候，會先傳到standbylogfile 然後由standby的arcn進行歸檔 ,若沒建立standbylogfile 時候將由rfs程式直接寫到standby_archive_dest位置
若沒有設定standby_archive_dest將自動建立在db_recover_file_dest下（standby）

總結 以上arcn 就傳遞方式 當 建立了standby logfile時候 rfs 先傳遞到standbylogfile 再由standby的 arcn程式歸檔到standby本地歸檔位置
沒有建立standbylogfile時候rfs程式 將歸檔（主庫）直接傳遞到standby_archive_dest中，沒有standby_archive_dest 將傳到standby的 db_recover_file_dest中
當 關閉standby db_recover_file_dest,現在standby_archive_dest也關閉，也沒有 standbylogfile 將在standby log_arhive_dest_1中
standbylogfile>standby_archive_dest>db_recovery_file_dest
rfs(程式很重要) 在standby
SQL> alter system set log_archive_dest_2='service=standby1 lgwr sync valid_for=(
online_logfiles,primary_role) db_unique_name=standby1'
注意 以上這些 是在主庫 設定成log_archive_dest_n='service' arcn的情況
（二）LGWR
實時應用
在主庫設定
SQL> alter system set log_archive_dest_2='service=standby1 lgwr async valid_for
=(online_logfiles,primary_role) db_unique_name=standby1';
系統已更改。 lgwr裡面又分sync,async
當開了lgwr 的時候 sync時 過程是 當log_buffer的redo資料寫入redofile 同時 primary的lgwr邊寫入primary 的online logfile;邊開啟lsnn程式（主庫） 傳遞到standby，由standby的rfs程式，寫入standbylogfile ，sync指定的是同步，此時primary的事務會一直保持，知道含有lgwr sync的所有log_archive_dest_n都接收完畢
lgwr主要是開啟實時應用~~~若在standby 沒有設定standbylogfile primary設定了lgwr ,sync或async
SQL> alter system set log_archive_dest_2='service=standby1 lgwr sync valid_for=( 主庫
online_logfiles,primary_role) db_unique_name=standby1'
2 ;
系統已更改。
SQL> select * from v$standby_log; （STANDBY ）
未選定行 經過查詢standby沒有 standbylogfile
所以即便主庫設定了lgwr,sync等也 無法使用 實時應用
例
SQL> select * from test;
未選定行
SQL> insert into test values(1);
已建立 1 行。
SQL> commit;
提交完成。 主庫插入資料並且寫入onlinelogfile

總結：經過反覆2次實驗，發現在no standbylogfile 時候 當日志傳輸配置的是lgwr~~~~~~~時候會歸檔到standby_archive_dest中，建立的程式是lgwr直接傳遞過去
standby_archive_dest沒有，alert.log中會先記錄一個錯誤 ORA-16032: parameter STANDBY_ARCHIVE_DEST destination string cannot be translated~ ，然後會記錄Using STANDBY_ARCHIVE_DEST parameter default value as USE_DB_RECOVERY_FILE_DEST ，將使用standby_archive_dest 預設值為db_reocvery_file_dest，會傳遞到db_recovery_file_dest中，如果db_reocvery_file_dest也沒有 建立者還是lgwr，如果db_recovery_file_dest 也沒有設定
那麼 在主庫向standby傳遞日誌的時候會很慢 並且關閉了rfs lgwr程式，啟動了預設的arch程式歸檔到standby的本地歸檔位置log_archive_dest_1
,但過經過幾次傳遞 oracle又將自動啟動lgwr傳遞到standby的本地歸檔位置log_archive_dest_1
