Exadata存储节点报ORA-07445 [0000000000000000+0][11]

1、今天，同事在日常检查时发现Exadata的某个存储节点报了个ORA-07445的错误，他查了查，怀疑是个BUG，让我帮着确认一下。错误日志如下

[root@dm01celadm03 ~]# cellcli -e list alerthistory

1 2022-02-23T14:38:54+08:00 critical "ORA-07445: exception encountered: core dump [0000000000000000+0] [11] [0x000000000] [] [] []"

 

2、看到这种ORA-07445，大部分情况下都是因为软件BUG所致，让同事将故障期间的alert日志发了出来。

2022-02-23T14:38:54.220527+08:00

3、通过关键字搜索，找到了《Exadata: Intermittent cellsrv crashes with ORA-07445: [0000000000000000+0] [11] [0x000000000] after upgrading to 12.2.1.1.7 or 12.2.1.1.8 (Doc ID 2421083.1)》。还真是一个BUG（28181789）。

 

4、后续需要跟客户反馈这个问题，找机会进行补丁安装。
