1设置Oracle10g 支持RedHat 5 参数 # vi /etc/redhat-release

以可以通过修改安装文件oraparam.ini,添加redhat-5（二者选一即可）

# vi /10201_database_linux32/database/install/oraparam.ini

2创建用户和组

[root@node1 ~]# groupadd oinstall
[root@node1 ~]# groupadd dba
[root@node1 ~]# useradd -d /home/oracle -g oinstall -G dba oracle

设置oracle用户密码
[root@node1 ~]# passwd oracle
Changing password for user oracle.
New UNIX password:
BAD PASSWORD: it is based on a dictionary word
Retype new UNIX password:
passwd: all authentication tokens updated successfully.

提示：
[root@node1 ~]# id oracle
uid=500(oracle) gid=500(oinstall) groups=500(oinstall),501(dba)

3设置环境变量

# Oracle Settings

TMP=/tmp; export TMP

TMPDIR=$TMP; export TMPDIR

ORACLE_BASE=/oracle; export ORACLE_BASE

ORACLE_HOME=$ORACLE_BASE/product/10.2.0/db_1; export ORACLE_HOME

ORACLE_SID=orcl; export ORACLE_SID

ORACLE_TERM=xterm; export ORACLE_TERM

PATH=$PATH:$ORACLE_HOME/bin; export PATH

LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME/lib;export LD_LIBRARY_PATH

CLASSPATH=$ORACLE_HOME/JREORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib; export CLASSPATH

4打补丁

rpm -q gcc make binutils openmotif setarch compat-db compat-gcc compat-gcc-c++ compat-libstdc++ compat-libstdc

注意libXp的32位包

1.1    设置内核参数 #vi /etc/sysctl.conf 末行添加以下内容

 kernel.shmall = 2097152

kernel.shmmax = 2147483648

kernel.shmmni = 4096

kernel.sem = 250 32000 100 128

fs.file-max = 65536

net.ipv4.ip_local_port_range = 1024 65000

net.core.rmem_default=262144

net.core.rmem_max=262144

net.core.wmem_default=262144

net.core.wmem_max=262144

运行下面命令使得内核参数生效

 sysctl –p

1.2    设置参数 # vi /etc/pam.d/login    末行添加以下内容

session required /lib/security/pam_limits.so

添加以下行到/ect/security/limits.conf文件中

  * soft nproc 2047

* hard nproc 16384

* soft nofile 1024

* hard nofile 65536
