配置系统内核参数
vi /etc/sysctl.conf
net.ipv4.ip_forward = 0 net.ipv4.conf.default.rp_filter = 1 net.ipv4.conf.default.accept_source_route = 0 kernel.sysrq = 0 kernel.core_uses_pid = 1 net.ipv4.tcp_syncookies = 1 kernel.msgmnb = 65536 kernel.msgmax = 65536 kernel.shmmax = 4294967295 kernel.shmall = 268435456 fs.aio-max-nr = 1048576 fs.file-max = 6815744 kernel.shmall = 2097152 kernel.shmmax = 536870912 kernel.shmmni = 4096 kernel.sem = 250 32000 100 128 net.ipv4.ip_local_port_range = 9000 65500 net.core.rmem_default = 262144 net.core.rmem_max = 4194304 net.core.wmem_default = 262144 net.core.wmem_max = 1048586
接着 限制shell命令
[root@testrac1 ~]# vi /etc/security/limits.conf testrac1**和testrac2修改**
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
oracle soft stack 10240
grid soft nproc 2047
grid hard nproc 16384
grid soft nofile 1024
grid hard nofile 65536
grid soft stack 10240
接着 给session相关的限制模块打开
**[root@testrac1 ~]# vi /etc/pam.d/login testrac1****和****testrac2****修改**
session required /lib/security/pam_limits.so
接着 给oracle 用户的shell的一个限制
#vi /etc/profile testrac1**和testrac2都要修改**
if [ $USER = "oracle" ]||[ $USER = "grid" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi
给另外一个节点传输文件
[root@testrac1 app]# scp /etc/profile 192.168.56.101:/etc/profile
