早上查看数据库alert日志,发现如下ORA-报错:

kgxpvfynet: mtype: 61 process 6460 failed because of a resource problem in the OS. The OS has most likely run out of buffers (rval: 4)
Errors in file /u01/app/oracle/diag/rdbms/orcl/orcl2/trace/orcl2_ora_6460.trc (incident=176003):
ORA-00603: ORACLE server session terminated by fatal error
ORA-27504: IPC error creating OSD context
ORA-27300: OS system dependent operation:sendmsg failed with status: 105
ORA-27301: OS failure message: No buffer space available
ORA-27302: failure occurred at: sskgxpsnd2

 

经过搜索MOS ,给出的结论是 这是由于网络缓冲区保留空间不足造成的。

vm.min_free_kbytes should be set in the order of 0.4% of total Physical Memory

 

解决方案:

 

1. 增大操作系统内核参数vm.min_free_kbytes 的值

 

由于本机物理内存128G,故此处增大到:  vm.min_free_kbytes = 524288

sysctl -p 使参数生效

 

2. 还建议修改lo网卡MTU的值

 

#ifconfig lo mtu 16436

 

#vi  /etc/sysconfig/network-scripts/ifcfg-lo 

MTU=16436

 

重启网络服务:
 
#service network restart
