可以通过调整参数min_free_kbytes 设置,这个参数要设置到总内存的0.4%以下, 比如256GB RAM,vm.min_free_kbytes 设置 1073742,可以设置更小。 numa模式的参考Oracle Linux: ORA-27301:OS Failure Message: No Buffer Space Available (Doc ID 2041723.1) 然后修改mtu ###临时修改 ifconfig lo mtu 16436 永久生效...
Oracle Linux: ORA-27301:OS Failure Message: No Buffer Space Available (Doc ID 2041723.1) 发生这种情况的原因是可用于网络缓冲区预留的空间较少。 一 修改NTU vi /etc/sysconfig/network-scripts/ifcfg-lo MTU=16436 1. 2. root# systemctl restart network 1. 2. 二、修改系统参数 设定vm.min_free_kby...
