3. 设置oracle用户的shell limit
oracle11 hard nproc 16384 oracle11 soft nofile 1024 oracle11 hard nofile 65536
4. 运行 "runInstaller" 进行安装
其中有一步会检查系统是否缺少依赖组件,若缺少,用红帽安装光盘安装相应rpm包即可
若系统没有设置交换分区,也会提示错误,忽略这个错误
其他的按照提示一步步操作即可,直到安装成功
5. 设置环境变量
安装成功后,$ORACLE_HOME, $ORACLE_SID这些环境变量并没有添加,为了使用方便,手动添加下
打开 "~/.bashrc",设置如下环境变量
export ORACLE_HOME=/home/oracle11/app/oracle11/product/11.2.0/dbhome_1 export ORACLE_SID=orcl export PATH=$PATH:$ORACLE_HOME/bin
6. 开启启动数据库
1) 编辑 /etc/oratab,将最后一个参数"N"设为"Y"
orcl:/home/oracle11/app/oracle11/product/11.2.0/dbhome_1:Y
#!/bin/sh #chkconfig: 2345 99 01 #description: ORACLE 11g Server ORACLE_HOME=/home/oracle11/app/oracle11/product/11.2.0/dbhome_1 if [ ! -f $ORACLE_HOME/bin/dbstart ]; then echo "ORACLE cannot start" exit fi case "$1" in 'start') echo "Starting Oracle11 Database..." su - oracle11 -c "$ORACLE_HOME/bin/dbstart" su - oracle11 -c "$ORACLE_HOME/bin/emctl start dbconsole" ;; 'stop') echo "Stoping Oracle Database" su - oracle11 -c "$ORACLE_HOME/bin/emctl stop dbconsole" su - oracle11 -c "$ORACLE_HOME/bin/dbshut" ;; esac
