RMAN備份alert日志報奇怪錯誤

布置Rman備份計劃，執(zhí)行之后發(fā)現alert.log中產生錯誤信息：
Fri Jul  6 00:30:16 2012
Errors in file /Oracle/admin/live/udump/*****_ora_3652.trc:
Fri Jul  6 00:30:16 2012
Errors in file /Oracle/admin/live/udump/*****_ora_3652.trc:
 

Fri Jul  6 00:30:16 2012
Errors in file /Oracle/admin/live/udump/*****_ora_3652.trc
 
然后檢查備份日志，沒有發(fā)現錯誤，奇怪，查看一下trace文件

metalink 解釋是一個bug 4596065，只發(fā)生在Linux X86平臺的Oracle 10.2.0.1.0下，而且只在11g里解決。這個并不是真正意義的error，可以不用管它,Just ignore it?

Problem statement:

RMAN BACKUP GENERATES EMPTY TRACE FILES WHEN DB_RECOVERY_FILE_DEST IS SET

 
網上搜索發(fā)現很多人亦遇到此情況
見鏈接 http://www.linuxidc.com/Linux/2012-07/64645.htm
有如下解釋亦可接受：
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.
 
該錯誤信息根不必去追究和關心了，Just ignore it
