故障现象：并未发现系统异常

1.3故障分析及解决
1.3.1获取对应的Trace Log
根据Alert Log中对应的文件路径，获取对应的Trc文件
获取到如下信息
*** 2018-12-25 22:10:01.139
*** SESSION ID:(442.63835) 2018-12-25 22:10:01.140

error: pos=0, message follows:

status=(pst=ERROR)
status=(pst=ERROR)
结合ORA报错的提示
ORA报错List如下
ORA-12012: error on auto execute of job “SYS”.“ORA$AT_SQ_SQL_SW_3262”
ORA-01565: error in identifying file ‘+DATA/FDCOFFDB/temp02.dbf’
ORA-17503: ksfdopn:2 Failed to open file +DATA/FDCOFFDB/temp02.dbf
ORA-15064: communication failure with ASM instance
ORA-06512: *4个文件
通过Log可以简单看出
首先是系统在自动执行‘ORA$AT_SQ_SQL_SW_3262’时出现错误，导致无法识别temp02.dbf文件，从而导致无法打开temp02.dbf文件，（可能）导致与ASM通讯失败
通过Alert Log可以看出该Job正在执行Resize 的动作，且可能与Job ‘YS_AUTO_SQL_TUNING_TASK’相关
今日的发现暂时是这样，明日如有更新会继续补充
