基于CentOS与VmwareStation10搭建Oracle11G RAC 64集群环境：2.搭建环境-2.7. 配置资源与参数

2.7.配置资源与参数

2.7.1. 修改主机名称

[root@linuxrac1 ~]# cd /etc/sysconfig

[root@linuxrac1 sysconfig]# vi network

NETWORKING=yes

NETWORKING_IPV6=no

HOSTNAME=linuxrac1

[root@linuxrac1 sysconfig]#

[root@linuxrac2 ~]# cd /etc/sysconfig

[root@linuxrac2 sysconfig]# vi network

NETWORKING=yes

NETWORKING_IPV6=no

HOSTNAME=linuxrac2

[root@linuxrac2 sysconfig]#

2.7.2. 配置用户,组,目录和权

　　创建组之前要确认一下/etc/group及/etc/passwd下的组及用户，确保每个节点上的uid及gid 一致 (当然也可以建组的时候加入id号，groupadd -g 501 oinstall) .

　　根据规划：

　　Grid Infrastructure操作系统用户grid , 主组为oinstall，辅助组为asmadmin, asmdba, asmoper

　　Oracle RAC操作系统用户oracle , 主组为oinstall , 辅助组为dba, oper , asmdba

[root@localhost /]# groupadd oinstall

[root@localhost /]# groupadd dba

[root@localhost /]# groupadd oper

[root@localhost /]# groupadd asmadmin

[root@localhost /]# groupadd asmdba

[root@localhost /]# groupadd asmoper

[root@localhost /]# useradd -g oinstall -G dba,asmdba,asmadmin,asmoper grid

[root@localhost /]# useradd -g oinstall -G dba,oper,asmdba oracle

[root@localhost /]# echo -n oracle|passwd --stdin grid

Changing password for user grid.

passwd: all authentication tokens updated successfully.

[root@localhost /]# echo -n oracle|passwd --stdin oracle

Changing password for user oracle.

passwd: all authentication tokens updated successfully.

[root@localhost /]# mkdir -p /u01/app/11.2.0/grid

[root@localhost /]# mkdir -p /u01/app/grid

[root@localhost /]# mkdir -p /u01/app/oracle

[root@localhost /]# chown grid:oinstall /u01/app/11.2.0/grid

[root@localhost /]# chown grid:oinstall /u01/app/grid

[root@localhost /]# chown -R oracle:oinstall /u01/app/oracle

[root@localhost /]# chmod -R 777 /u01/

[root@localhost /]# chown -R grid:oinstall /u01

2.7.3.修改系统内核参数/etc/sysctl.conf

[root@linuxrac1 etc]# vi sysctl.conf

# add parameter for oracle

fs.aio-max-nr = 1048576

fs.file-max = 6815744

kernel.shmall = 2097152

kernel.shmmax = 1073741824

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

2.7.4.配置/etc/security/limits.conf

[root@linuxrac1]# vi /etc/security/limits.conf

#add parameter for oracle and grid

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

2.7.5. 配置/etc/profile

[root@linuxrac1 etc]# vi profile

# for oracle

if [ \$USER = "oracle" ] || [ \$USER = "grid" ];then

if [ \$SHELL = "/bin/ksh" ];then

ulimit -p 16384 ulimit -n 65536

else

ulimit -u 16384 -n 65536

fi

umask 022
