• EXADATA X5数据库一体机的第2个计算节点,在5月13日的11:11分出现了服务器异常无响应的现象,表现为无法登录(ILOM口登录时报错login: failure forking: Cannot allocate memory)、数据库集群的资源无法关闭-无法连接使用;工程师在发现问题后,及时进行响应,已经及时恢复业务。并且及时到机房进行节点2服务器的重启和进行相应内存配件维修更换,目前一体机运行正常,一体机上的各个数据库运行正常;
  • 节点2的服务器异常问题分析
    1. 告警服务器异常的时间节点

5月13日的11:11分,容灾平台发出告警,X5一体机的节点2连接异常:

告警级别:灾难

开始时间:2026-05-13 11:10:18

结束时间:

容灾组:X5B

资源名:X5B-Master-25-TEST

地址:10.134.126.14

告警信息:代理程序状态异常

    1. 服务器登录报错

在X5的节点2服务器重启时,服务器登录报错、无法登录,相应的数据库HANG主无法使用。登录时报错如下:

-> start /SP/console

Are you sure you want to start /SP/console (y/n)? y

Serial console started.  To stop, type ESC (

dm01db02.watone.com.cn login: root

Password:

Last login: Thu May  7 11:55:21 from dm01db01

login: failure forking: Cannot allocate memory

节点2上面的数据库HANG住无法通过集群命令进行关闭:

[oracle@dm01db01 ~]$ srvctl stop instance -d LSFCJYDB -i lsfcjydb2

PRCR-1133 : Failed to stop database lsfcjydb and its running services

PRCR-1132 : Failed to stop resources using a filter

ORA-12549: TNS:operating system resource quota exceeded

CRS-2675: Stop of 'ora.lsfcjydb.db' on 'dm01db02' failed

CRS-2678: 'ora.lsfcjydb.db' on 'dm01db02' has experienced an unrecoverable failure

CRS-5804: Communication error with agent process

    1. 服务器硬件日志

从服务器硬件管理平台上的信息来看,/SYS/MB/P0/D5槽位的内存出现告警fault.memory.intel.dimm_ce,建议进行更换:

日志信息如下:

[root@dm01db02 ~]# ipmitool sunoem cli "show faulty"

Connected. Use ^D to exit.

-> show faulty
