最近，我遇到了Oracle 11g的问题。它经常停止工作，每隔几个小时，并且必须再次启动。这从未发生过，它刚刚在上个月开始。
以下是clsc.log文件的内容
2016-10-06 07:00:14.344: [ default][2031720192]utgdv:2:ocr loc file /etc/oracle/olr.loc cannot be opened. errno 2
[ CLSE][2031720192]clse_get_crs_home: Error retrieving OLR configuration [0] [Error opening olr.loc file. No such file or directory]
任何人都可以帮助我吗？
编辑：这里有警报日志消息，每次实例都停止工作（在这种情况下，它已经在周三晚上停止工作，并在周四再次开始）
