Oracle Rman backup 產生的錯誤信息

周日手工做RMAN備份的時候，在alert.log中產生了錯誤信息。

      奇怪呀，RMAN也沒有報錯信息，趕快看看trc文件：

      沒有什么過多的錯誤信息顯示，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.
