1，修改内核

1.1 修改sysctl.conf文件

[root@orcltest Downloads]# vim/etc/sysctl.conf

# add by tim.man kernel.shmmax = 277495689510912 kernel.shmmni = 4096 kernel.sem = 250 32000 100 128 net.core.rmem_default = 262144 net.core.rmem_max = 4194304 net.core.wmem_default = 262144 net.core.wmem_max = 1048586 fs.file-max = 6815744 # Controls the maximum number of shared memory segments, in pages                                                                                                                       kernel.shmall = 4294967296 net.ipv4.tcp_max_tw_buckets = 6000 net.ipv4.ip_local_port_range = 9000 65500 net.ipv4.tcp_tw_recycle = 0 net.ipv4.tcp_tw_reuse = 1 net.core.somaxconn = 262144 net.core.netdev_max_backlog = 262144 net.ipv4.tcp_max_orphans = 262144 net.ipv4.tcp_max_syn_backlog = 262144 net.ipv4.tcp_synack_retries = 2 net.ipv4.tcp_syn_retries = 1 net.ipv4.tcp_fin_timeout = 1 net.ipv4.tcp_keepalive_time = 30 net.ipv4.tcp_keepalive_probes = 6 net.ipv4.tcp_keepalive_intvl = 5 net.ipv4.tcp_timestamps = 0 fs.aio-max-nr = 1048576

1.2 使参数生效

[root@orcltest Downloads]# sysctl –p

2，增加用户和组

[root@orcltestDownloads]# groupadd oinstall

[root@orcltestDownloads]# groupadd dba

[root@orcltestDownloads]# groupadd oper

[root@orcltestDownloads]# useradd -g oinstall -G dba,oper oracle

[root@orcltestDownloads]# passwd oracle

3，修改limits.conf限制

[root@orcltestDownloads]# vim /etc/security/limits.conf

oracle soft nproc 2047  oracle hard nproc 16384                                                                                               oracle soft nofile 1024 oracle hard nofile 65536

4，修改/etc/pam.d/login

[root@orcltestDownloads]# vim /etc/pam.d/login

session required/lib64/security/pam_limits.so

5，修改bash_profile文件

（1）修改profile：

[root@orcltest Downloads]# vim /etc/profile                                                           # add by tim.man if [ $USER = "oracle" ]; then if [ $SHELL = "/bin/ksh" ]; then    ulimit -p 16384    ulimit -n 65536 else    ulimit -u 16384 -n 65536 fi fi

（2）修改bash_profile：
