本地有一個小的環境，今天照例登上sqlplus，突然發現報瞭如下的錯誤。一看原來歸檔滿了。我記得前幾天做一個批量操作臨時把temp檔案resize了很大，限於本地空間有限。準備改回去。把多餘的歸檔刪除了。

sqlplus n1/n1 
.... 
ERROR: 
ORA-00257: archiver error. Connect internal only, until freed.

這個時候sysdba的許可權發揮作用了，它可以照常登入。然後開始做resize操作。

SQL> alter database tempfile '/u03/ora11g/oradata/TEST01/temp01.dbf' resize 100M;

但是等了好一會兒，一直沒有輸出。是不是Hang住了。

看來得刪除歸檔檔案了。然後到歸檔目錄下嘗試刪除，結果這個時候rm似乎不管用了，命令執行了，但是歸檔檔案還在那。我想是不是有系統級的問題了。

決定重啟 ，重啟以後，Mount狀態過後就很不留情的報了一個03113的錯誤。

檢視alert日誌檔案。看到重做日誌歸檔失敗。

因為是測試環境，所以採用瞭如下的方法，啟動到Mount階段之後

檢視日誌檔案情況

這個時候重新執行temp檔案的resize，就沒有問題了。

SQL> alter database tempfile '/u03/ora11g/oradata/TEST01/temp01.dbf' resize 100M;
Database altered.
