oracle11g dataguard failover重建後歸檔日志沒有被應用被NO的問題

1，主庫從庫歸檔記錄不一緻，如下所示：

做完failover後，壞的舊主庫變成了新的從庫，但是新從庫的歸檔日志記錄不一緻，就是archive log list;出來的和v$archived_log出來對不上号，如下所示：

1.1 主庫：

SQL> archive log list;
Database log mode	       Archive Mode
Automatic archival	       Enabled
Archive destination	       USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence     8
Next log sequence to archive   10
Current log sequence	       10
SQL> 
           

SQL>  select sequence#,applied from v$archived_log order by sequence# asc;
......
---------- ---------
      7527 YES
      7527 YES
      7528 YES
      7528 YES
      7529 YES
      7530 YES
      7531 YES
      7532 YES
      7533 YES

14529 rows selected.
           

大家可以看到主庫中archive log list和v$archived_log記錄歸檔不一緻。

1.2 從庫：

SQL> archive log list;
Database log mode	       Archive Mode
Automatic archival	       Enabled
Archive destination	       USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence     10
Next log sequence to archive   0
Current log sequence	       10
SQL> 
           

SQL> select sequence#,applied from v$archived_log order by sequence# asc;

 SEQUENCE# APPLIED
---------- ---------
	 9 IN-MEMORY

SQL>
           

從庫的歸檔也一直沒有被應用，而且兩者也查了一個數字差，一個為10，一個為9。

PS：大家看到主庫和從庫歸檔号沒有統一起來，不一緻。

2，清除新主庫的歸檔記錄

問題原因是在新主庫上保留的還是舊主庫的歸檔日志記錄，需要手工清理一下，在新主庫上執行清除記錄：

SQL> execute sys.dbms_backup_restore.resetCfileSection(11);

PL/SQL procedure successfully completed.

SQL> 
SQL> 
SQL>  select sequence#,applied from v$archived_log order by sequence# asc;

no rows selected

SQL> 
           

去歸檔日志目錄，人為删除舊的歸檔日志

[[email protected]_standby1 archivelog]$ rm -rf 2015_12_13/ 2015_12_19 2015_12_20 2015_12_21 2015_12_22 2015_12_23 2015_12_24 2015_12_25
[[email protected]_standby1 archivelog]$ 
           

然後進入rman執行

RMAN> catalog db_recovery_file_dest;
RMAN> catalog db_recovery_file_dest;

using target database control file instead of recovery catalog
searching for all files in the recovery area

List of Files Unknown to the Database
=====================================
File Name: /oracle/app/oracle/flash_recovery_area/STANDBY/onlinelog/o1_mf_9_c7c1v5qw_.log

Do you really want to catalog the above files (enter YES or NO)? YES

cataloging done

List of Cataloged Files
=======================
File Name: /oracle/app/oracle/flash_recovery_area/STANDBY/archivelog/2015_12_26/o1_mf_1_9_c7wqvrp9_.arc

List of Files Which Where Not Cataloged
=======================================
File Name: /oracle/app/oracle/flash_recovery_area/STANDBY/onlinelog/o1_mf_9_c7c1v5qw_.log
  RMAN-07529: Reason: catalog is not supported for this file type

  RMAN-07529: Reason: catalog is not supported for this file type

RMAN> exit
           

然後進入sql指令檢視：

SQL>  select sequence#,applied from v$archived_log order by sequence# asc;

 SEQUENCE# APPLIED
---------- ---------
	 9 NO

SQL> 
           

3，之後switch切換日志測試

主庫：

SQL> alter system switch logfile;

System altered.

SQL>  select sequence#,applied from v$archived_log order by sequence# asc;

 SEQUENCE# APPLIED
---------- ---------
	 9 NO
	10 NO
	10 NO

SQL> 
           

從庫：

SQL> select sequence#,applied from v$archived_log order by sequence# asc;

 SEQUENCE# APPLIED
---------- ---------
	 9 YES
	10 YES

SQL> 
           

看到兩邊歸檔日志以及被應用情況都一緻了。
