Oracle Rman backup 產生的錯誤資訊

周日手工做RMAN備份的時候，在alert.log中產生了錯誤資訊。

      奇怪呀，RMAN也沒有報錯資訊，趕快看看trc檔案：

      沒有什麼過多的錯誤資訊顯示，基本上也是一些說明性的東西。只在metalink的forum中有這樣的提問和回答。其中一位ORACLE的support的回答比較嚴謹吧：
     
There seems to be apparently no problem with the trace file that is getting generated.

However is it the full trace file or have you just pasted the heading of the trace file.

You are correct in interpreting that this is related to the backup.

If this is not the full tracefile you can update the thread with some more information or atleast the call stack part of the trace file.

If this is the full file, then there is nothing much that can be inferred from it, and can be ignored.

      好了，這個問題可以不追究了。
      記錄一下吧。
      對一個資料的管理員來講，不要放過任何資料庫產生的資訊才對。嚴謹，是必須的。-:)
