1.分析alert中错误原因:

出现该问题是 Bug:8967729/unpublished bug 8730312
Active Session History中某些数据(the moduile, action program, etc. information)未被正确存储,然后awr程序在整点(默认配置)的时候访问V$ACTIVE_SESSION_HISTORY 视图失败,从而出现了该错误.出现该问题可能导致ash和awr使用异常或不准确

2.问题解决:

1.在Oracle12c release and the 11.2.0.2 and higher patchsets中被修复
2.打上one-off Patch:8730312(one-off补丁没有经过oracle的严格测试,在打该补丁前可能需要进行测试)
