批量處理物理備庫出現archive gap

物理備庫出現gap，主庫為5節點RAC，資料庫版本10.2.0.5

登入物理備庫
SQL> select * from v$archive_gap;

   THREAD# LOW_SEQUENCE# HIGH_SEQUENCE#
---------- ------------- --------------
         1        122309         122325
         3          3517           3525
發現gap比較多，以前出現一個archive gap的時候，我們通常是在RAC主庫使用rman命令copy，即將ASM格式的archivelog改為普通格式的，然後傳到備庫register並recover
這次gap太多，用這個方法太慢了，更換一個
在主庫一個節點上rman執行
backup archivelog from sequence 122309 until sequence 122325 thread 1;
backup  archivelog from sequence 3517 until sequence 3525 thread 3;
然後將備份集傳到備庫
先使用catalog start with將這兩個備份集註冊到控制檔案，然後使用restore恢復出archivelog
RMAN> restore archivelog from sequence 122309 until sequence 122325 thread 1;

此時alertlog相應記錄為

此時v$archive_gap已經沒有了記錄
SQL> select * from v$archive_gap;

no rows selected
但是recover程式不會自動恢復這些log，需要先cancel再開啟
SQL> recover managed standby database cancel;
Media recovery complete.
SQL> recover managed standby database using current logfile disconnect from session;
Media recovery complete.
此時備庫恢復正常
