Time drifts can result in an unexpected behavior such as time-outs. Please check trace file for more details.
经过查询官方文档，证实是由于oracle11.2.0.4上的bug引起的（官方文档ID 1678120.1）
This problem is due to the Bug 11837095 - "TIME DRIFT DETECTED" APPEARS INTERMITTENTLY IN ALERT LOG"
处理方法为：
1.在实例上设置一个事件，使这个告警信息不再出现：
SQL> alter system set event="10795 trace name context forever, level 2" scope=spfile;
2.重启实例使之更改生效
