aix7.1.3.8上面的Oracle 12C 的alert日志中经常会出现报错，请问如何处理？

An internal routine has requested a dump of selected redo.
This usually happens following a specific internal error, when
analysis of the redo logs will help Oracle Support with the
diagnosis.
It is recommended that you retain all the redo logs generated (by
all the instances) during the past 12 hours, in case additional

redo dumps are required to help with the diagnosis.
