三、修改了监听端口, 怎样保证 DB Control 正常运行
1. 修改 listener.ora 和tnsnames.ora 这两个文件:
tnsnames.ora 中需要加入:

listener_1 =
(ADDRESS = (PROTOCOL = TCP)
(HOST = xxxx)(PORT = 新的端口))

然后启动数据库:

SQL> show parameter local_listener ;
SQL> alter system set local_listener=’listener_1′ scope=spfile;

重启数据库使得修改生效

2. 修改 $ORACLE_HOME\hostname_sid\sysman\config
下的emoms.properties文件:

oracle.sysman.eml.mntr.emdRepPort=新的端口
oracle.sysman.eml.mntr.emdRepConnectDescriptor =(DESCRIPTION\=(ADDRESS_LIST\=(ADDRESS\=(PROTOCOL\=TCP)(HOST\=xxx)(PORT\= 新的端口)))(CONNECT_DATA\=(SERVICE_NAME\=xxx)))

3. 最后，还要修改 $ORACLE_HOME\hostname_sid\sysman\emd
下的targets.xml:

4. 重新启动监听器和dbconsole 服务.

5. 如果嫌上面的操作麻烦，可以用emca这个命令行工具:
emca -h 查看所有可用的命令
emca -r 跳过资料档案库的创建.

一、安装前的准备

1.硬件要求

Oracle建议内存为512MB或以上,至少1G交换分区，并且需要400MB的临时目录空间。
使用以下的命令查看你的内存和交换分区大小：

# grep MemTotal /proc/meminfo
# grep SwapTotal /proc/meminfo

你可以使用以下方法添加临时交换分区：

su – root
dd if=/dev/zero of=tmpswap bs=1k count=900000
chmod 600 tmpswap
mkswap tmpswap
swapon tmpswap

可以通过以下命令查看临时空间大小：

#df /tmp

可以自己新建临时目录，安装完后再删除

#su – root
#mkdir /opt/tmp
#chown root.root /opt/tmp/
# chmod 1777 /opt/tmp
# echo TEMP
# export TEMP=/opt/tmp
# export TEMPDIR=/opt/tmp

对硬盘空间大小的限制，建议预留3G空间。

2.系统参数调整

修改/etc/sysctl.conf，添加

＃我的机器只有1G内存
kernel.shmmax = 1073741824
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.file-max = 65536
net.ipv4.ip_local_port_range = 1024 65000

执行
#/sbin/sysctl -p

设置shell限制,在/etc/security/limits.conf添加
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536

修改login设置，修改 /etc/pam.d/login，添加
session required /lib/security/pam_limits.so

在/etc/profile中添加以下语句：

if [ $USER = "oracle" ]; then
if [ $SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
fi

3、安装设置

确保你已经安装了下列软件

sudo apt-get install gcc make binutils lesstif2 libc6 libc6-dev rpm libmotif3 libaio1 libstdc++5 gawk
确保你的系统中有以下组和用户，方法：

#grep dba /etc/group
#grep oinstall /etc/group
#grep nobody /etc/group

#id oracle
#id nobody

切换到root，添加oralce帐户

#su – root
#groupadd dba # group of users to be granted SYSDBA system privilege
#groupadd oinstall # group owner of Oracle files
#useradd -c “Oracle software owner” -g oinstall -G dba -d /opt/oracle oracle
#passwd oracle
输入oracle密码

debian中需要额外的添加nobody用户组：
#groupadd nobody
系统nogroup组中已经有nobody用户，把nobody用户添加到新建的nobody组中，
#usermod -G nobody nobody

建立oracle目录
#su root
#mkdir /opt/oracle
#chown -R oralce.oinstall /opt/oracle
mkdir -p /u01/app
chown -R oracle.oinstall /u01/app
debian需要额外的做以下操作：
# ln -s /usr/bin/awk /bin/awk
# ln -s /usr/bin/rpm /bin/rpm
# ln -s /usr/bin/basename /bin/basename
# ln -s /etc /etc/rc.d

模拟redhat-3进行安装，新建一个文件/etc/redhat-release,写入以下内容：
Red Hat Enterprise Linux AS release 3 (Taroon)

二、开始安装

你可以从http://mirrors.cn99.com上下载oracle 10g,按以下方法进行解压：
su – oracle
wget http://mirrors.cn99.com/oracle/10g/10201_database_linux32.zip
unzip 10210_database_linux32.zip
若是远程连接到服务器，则需要这样操作：
ssh -X oracle@your_server_ip
export ORACLE_BASE=/u01/app
export ORACLE_SID=orcl #你可以自己命名sid
#确保此时环境中没有ORACLE_HOME 和TNS_ADMIN
$ unset ORACLE_HOME
$ unset TNS_ADMIN

可以将这些写进.bash_profile
export ORACLE_BASE=/opt/oracle
export ORACLE_SID=oralin
unset ORACLE_HOME
unset TNS_ADMIN

umask 022

执行
cd database
LC_ALL=en_US ./runInstaller

三、安装后

oracle启动脚本/etc/init.d/oracle

su
nano /etc/init.d/oracle

#!/bin/bash
#
# /etc/init.d/oracledb
#
# Run-level Startup script for the Oracle Instance, Listener, and
# Web Interface

export ORACLE_HOME=/u01/app/oracle/oracle/product/10.2.0/db_1/
export ORACLE_SID=orcl
export PATH=$PATH:$ORACLE_HOME/bin

ORA_OWNR="oracle"

# if the executables do not exist -- display error

if [ ! -f $ORACLE_HOME/bin/dbstart -o ! -d $ORACLE_HOME ]
then
echo "Oracle startup: cannot start"
exit 1
fi

# depending on parameter -- startup, shutdown, restart
# of the instance and listener or usage display

case "$1" in
start)
# Oracle listener and instance startup
echo -n "Starting Oracle: "
su $ORA_OWNR -c "$ORACLE_HOME/bin/lsnrctl start"
su $ORA_OWNR -c $ORACLE_HOME/bin/dbstart
touch /var/lock/oracle

su $ORA_OWNR -c "$ORACLE_HOME/bin/emctl start dbconsole"
su $ORA_OWNR -c "$ORACLE_HOME/bin/isqlplusctl start"
echo "OK"
;;
stop)
# Oracle listener and instance shutdown
echo -n "Shutdown Oracle: "
su - $ORA_OWNR -c "$ORACLE_HOME/bin/isqlplusctl stop"
su - $ORA_OWNR -c "$ORACLE_HOME/bin/emctl stop dbconsole"
su - $ORA_OWNR -c "$ORACLE_HOME/bin/lsnrctl stop"
su - $ORA_OWNR -c $ORACLE_HOME/bin/dbshut
rm -f /var/lock/oracle

echo "OK"
;;
reload|restart)
$0 stop
$0 start
;;
*)
echo "Usage: `basename $0` start|stop|restart|reload"
exit 1
esac
exit 0

chmod 755 /etc/init.d/oracledb
update-rc.d oracledb defaults 99

可以通过/etc/init.d/oracle start来启动oracle.

Step 2 Goto line 78
Step 3 Replace the line with
ORACLE_HOME_LISTNER=$ORACLE_HOME
Step 4 Save and exit the editor.
Step 5 Now reexecute the dbstart

REM This program is used to export data in Oracle to external files named with current date.
REM A simple export schema is employed. Monday the data will be completely exported.
REM Tuesday through Thursday data will be exported in an incremental manner.
REM Friday, data exported include all the incremental data since the last completed export.
REM Saturday and Sunday incremental export will be employed once more.

REM This program can be used together with Windows plan and task utility. In that way,
REM the program can be enhanced with running by schedule.
