Upgraded the database version to 11.2.0.4
CAUSE
This is due to Bug:18766012
SOLUTION
There are two Options to get rid of this Problem:
1. Ignore those Traces and create an OS-Job to regularly delete those Tracesfiles
2. Apply Patch 18766012 for your Platform on Top of 11.2.0.4 at least on the Standby Database.
Note that this Bug is fixed in 12.x, too.
对应Patch 18766012有两个对应的补丁：
p18766012_112040_Linux-x86-64.zip
p18766012_11204160419_Linux-x86-64.zip
两个我都检测过了，没有冲突。
然而无论哪个补丁，在线打或者离线打完之后，还是会产生大量的rfs的trc文件。
搞不懂。
