歸檔和非歸檔模式下ORA-01145錯誤的解決方法(87天)
阿新 • • 發佈：2022-05-04
總結了一下，在歸檔和非歸檔的場景下，ora-01145這個錯誤可能有如下三種情況：
1.off line tablespace
--在非歸檔模式下嘗試ofline 資料檔案
SQL> alter tablespace tools offline immediate;
alter tablespace tools offline immediate
*
ERROR at line 1:
ORA-01145: offline immediate disallowed unless media recovery enabled 以上操作需要在歸檔模式下才可以。
SQL> archive log list Database log mode Archive Mode Automatic archival Enabled Archive destination USE_DB_RECOVERY_FILE_DEST Oldest online log sequence 244 Next log sequence to archive 246 Current log sequence 246 SQL> alter tablespace tools offline immediate; Tablespace altered. --在非歸檔模式下可以採用如下 SQL> alter tablespace tools offline; Tablespace altered.
2.offline datafile
SQL> alter database datafile '/u01/app/oracle/oradata/disk_1/tbs01.dbf' offline; alter database datafile '/u01/app/oracle/oradata/disk_1/tbs01.dbf' offline * ERROR at line 1: ORA-01145: offline immediate disallowed unless media recovery enabled --在歸檔模式下，直接offline資料檔案就可以 SQL> alter database datafile '/u01/app/oracle/oradata/disk_1/tbs01.dbf' offline ; Database altered. --而在非歸檔模式下，需要先把表空間給offline掉，然後才能offline資料檔案，可以參見如下的例項。
3.offline drop
誤刪資料檔案後，這個需要 alter database datafile xxxxx offline drop;
--關於測試環境
庫為10g 10.2.0.1.0 非歸檔模式
表空間情況如下：
SQL> select tablespace_name,status from dba_tablespaces; TABLESPACE_NAME STATUS ------------------------------ --------- SYSTEM ONLINE SYSAUX ONLINE TEMPTS1 ONLINE TBS1 ONLINE TBS3 ONLINE TEMP1 ONLINE TEMP2 ONLINE TOOLS ONLINE OMF1 ONLINE UNDOTBS2 ONLINE
資料檔案情況如下：
SQL> select name,status from v$datafile;
NAME
--------------------------------------------------------------------------------
STATUS
-------
/u01/app/oracle/oradata/disk_4/system01.dbf
SYSTEM

--我嘗試將資料檔案tbs01給offline掉
SQL> alter database datafile '/u01/app/oracle/oradata/disk_1/tbs01.dbf' offline;
alter database datafile '/u01/app/oracle/oradata/disk_1/tbs01.dbf' offline
*
ERROR at line 1:
ORA-01145: offline immediate disallowed unless media recovery enabled 但是操作失敗，我記得平時都好好的，怎麼就不行了。
--檢視錯誤解析
SQL> !oerr ora 01145
01145, 00000, "offline immediate disallowed unless media recovery enabled"
// *Cause: ALTER TABLESPACE ... OFFLINE IMMEDIATE or ALTER DATABASE DATAFILE
// ... OFFLINE is only allowed if database is in ARCHIVELOG mode.
// *Action:Take tablespace offline normally or shutdown abort. Reconsider your
// backup strategy. You could do this if you were archiving your logs.我這個庫是非歸檔的，
SQL> alter tablespace tbs1 offline;
Tablespace altered.
SQL> alter database datafile '/u01/app/oracle/oradata/disk_1/tbs01.dbf' offline;
Database altered.
