MRP0- Background Media Recovery terminated with error 1111

Active DataGuard由於db_file_name_convert設定不當,導致資料檔案無法自動同步到備庫問題處理過程。

檢查db_file_name_convert參數配置。

 ls: cannot access /app/oracle/product/11.2.0/db_1/dbs/UNNAMED00035: No such file or directory

錯誤原因是由於在參數db_file_name_convert配置以外的磁碟組FRAJD_DG上建立資料表空間,路徑無法轉換導致資料檔案無法同步。

 解決辦法:
 備庫修改db_file_name_convert參數配置,將新的磁碟群組轉換添加到參數中。
alter system set db_file_name_convert='+DATA_JD_DG/pgs/datafile/','/data/pgs/datafile/','+DATA_JD_DG/pgs/tempfile/','/data/pgs/tempfile/','+FRAGT_DG/pgs/datafile/','/data/pgs/datafile/','+DATA_GT_DG/pgs/datafile/','/data/pgs/datafile/','+FRAJD_DG/pgs/datafile/','/data/pgs/datafile/' scope=spfile;
重啟備庫,只能將資料庫啟動到mount狀態:
shutdown immediate
 startup mount;

將備庫的standby_file_management參數修改為手動管理員模式
SQL> alter system set standby_file_management='MANUAL' scope=both;

 System altered.

把UNNAMED資料檔案放到正確路徑
SQL> alter database create datafile '/app/oracle/product/11.2.0/db_1/dbs/UNNAMED00035' as '/data/pgs/datafile/tbs_rpt_data.256.908366191';

 Database altered.

將備庫的standby_file_management參數修改回自動模式
SQL> ALTER SYSTEM SET STANDBY_FILE_MANAGEMENT=AUTO scope=both;

 System altered.

開啟即時應用日誌同步
SQL> alter database recover managed standby database using current logfile disconnect;

 Database altered.
