控制文件自动备份报错并产生TRACE文件

客户10.2.0.1数据库在控制文件自动备份过程中出现错误信息。
错误信息为:

Thu Jun 30 02:15:46 2011
Starting control autobackup
Thu Jun 30 02:15:47 2011
Errors IN file /u01/app/oracle/admin/orcl/udump/orcl_ora_1167402.trc:
Thu Jun 30 02:15:47 2011
Errors IN file /u01/app/oracle/admin/orcl/udump/orcl_ora_1167402.trc:
Thu Jun 30 02:15:47 2011
Errors IN file /u01/app/oracle/admin/orcl/udump/orcl_ora_1167402.trc:
Control autobackup written TO DISK device
	handle '/orch1/rmanbak/c-737336038-20110630-00'

这个错误信息很奇怪,首先没有明确的ORA-错误显示,而且最终控制文件的备份也成功了,看起来像是误报。
如果检查对应的TRACE文件,会发现文件中同样没有记录任何错误信息,检查MOS确认为10.2.0.1上的BUG 4596065,文档Trace File Created when RMAN issues the Controlfile Autobackup [ID 335731.1]描述了这个问题。
这个问题在10.2.0.2上被解决。在当前版本可以直接忽略这个问题。
