three:a dictionary managed tablesoace is one whose free space management is done in data dictionary that resides in system tablespace.
where as a locally managed tablespace means the free space for the tablespace is managed with in the tablespace using bitmaps.
locally managed tablespaces gives better performance in comparison to dmt.
but if ur system tablespace is locally managed then other tablespaces r also locally managed.
and in near future oracle may stop supporting dictionary managed tablespaces.

2，在表上建立触发器

create or replace trigger T_SUBJECTSUMRECORD
  before insert on subjectsumrecord 
  for each row
begin
  select S_SUBJECTSUMRECORD.nextval into :new.SUMRID from dual;
end S_SUBJECTSUMRECORD;

关于创建序列对象和触发器不详细讨论，将会在专门的文章中整理出来。

操作系统版本：
Red Hat Enterprise Linux AS release 3 (Taroon)
Kernel 2.4.21-4.EL on an i686
按照常规来安装操作系统,记得要安装开发工具(gcc等必要工具).

1.1 检查必要的硬件信息

检查内容	最小值	检查命令参考
物理内存	512M	# grep MemTotal /proc/meminfo
交换空间	1.0 GB或者2倍内存大小	# grep SwapTotal /proc/meminfo
/tmp 空间	400 MB	# df -k /tmp
软件所需空间	2.5 GB	# df -k (空间越大越好,如果是正式系统,应该进行详尽的规划)
数据库文件	1.2 GB	# df -k (空间越大越好,如果是正式系统,应该进行详尽的规划)

检查完如上各项之后, 应该修改核心参数.执行如下命令:

#vi /etc/sysctl.conf

#注释:
#表示使用root用户操作,$表示使用oracle 用户进行操作.提示符后面的蓝色部分表示需要输入的命令，以下同．

在该文件末尾加入如下内容:
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

编辑完之后,保存,执行 # /sbin/sysctl -p 命令操作来使我们所做的变更生效.
注:上面kernel.shmmax/kernel.sem等是典型的核心参数配置.您可能需要根据您的实际环境进行适当的变动.

关于这些核心参数的说明在Oracle的 Oracle9i Installation Guide Release 2 (9.2.0.1.0) for UNIX Systems 中有很详细的说明.( http://download-west.oracle.com/docs/html/A96167_01/toc.htm )

然后,应该检查一下上面的操作是否正确:
# /sbin/sysctl -a | grep sem
# /sbin/sysctl -a | grep shm
# /sbin/sysctl -a | grep file-max
# /sbin/sysctl -a | grep ip_local_port_range

为Oracle用户设定Shell的限制
一般来说，出于性能上的考虑,还需要需要进行如下的设定，以便改进Oracle用户的有关 nofile(可打开的文件描述符的最大数)和nproc(单个用户可用的最大进程数量)

# vi /etc/security/limits.conf
# 添加如下的行

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

添加如下的行到/etc/pam.d/login 文件：
session    required     /lib/security/pam_limits.so

编辑 /etc/profile 文件,添加如下部分：
if [ $USER = "oracle" ]; then 
        if [ $SHELL = "/bin/ksh" ]; then 
                ulimit -p 16384 
                ulimit -n 65536 
        else 
                ulimit -u 16384 -n 65536 
        fi 
fi
之后，执行$ ulimit 验证一下.

1.2 检查并安装相关补丁
在这个版本的RHEL上安装Oracle,必须要有几个软件包. 确认以下 rpm包都已经安装:

make-3.79
binutils-2.11
openmotif-2.2.2-16
setarch-1.3-1
compat-db-4.0.14.5
compat-gcc-7.3-2.96.122
compat-gcc-c++-7.3-2.96.122
compat-libstdc++-7.3-2.96.122
compat-libstdc++-devel-7.3-2.96.122

# rpm -qa | grep compat
# 在机器上输出如下:

compat-gcc-c++-7.3-2.96.122
compat-libstdc++-7.3-2.96.122
compat-libstdc++-devel-7.3-2.96.122
compat-glibc-7.x-2.2.4.32.5
compat-db-4.0.14-5
compat-gcc-7.3-2.96.122

# rpm -qa | grep openmotif
openmotif-devel-2.2.2-16
openmotif-2.2.2-16

# rpm -qa | grep setarch
setarch-1.3-1

上面显示的内容是在笔者已经安装了具体的RPM包之后的结果.一般情况下,你的系统上的输出结果和这个不同.如果个别包没有安装,把系统安装光盘mount上,找到具体的软件包(大多数在第三张光盘上),然后利用如下的命令来安装相应的包:
# rpm -ivh *.rpm

要额外注意的是,这些软件包之间是有依赖性的,先后的顺序要找好.否则会报告不能安装的错误. 此外，最好验证一下 gcc和glibc的版本(要求是gcc-3.2.3-2 或者更高):
#gcc -v
#rpm -q glibc

1.3 创建用户和相关的组
# /usr/sbin/groupadd oinstall
# /usr/sbin/groupadd dba
# /usr/sbin/useradd -g oinstall -G dba oracle　

如果只是测试目的的话，不创建oinstall组也没什么. 不过还是规范一点比较好.如果oracle 用户和dba组等已经存在，作适当的调整即可.

1.4 检查并调整环境变量
登录为oracle用户

# su - oracle
$ cd
$ vi .bash_profile

#添加如下内容,你的具体值应该不会和这个完全相同.
# oracle begin
export ORACLE_BASE=/datas/oracle
export ORACLE_HOME=$ORACLE_BASE/product/dbServer
export ORACLE_SID=audit
export PATH=$PATH:$ORACLE_HOME/bin
export BUILD_CCC296=1
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/usr/lib
export LC_CTYPE=en_US.UTF-8
export LC_TYPE=zh_CN.UTF-8
export NLS_LANG=AMERICAN_AMERICA.ZHS16GBK
export SQLPATH=$HOME/mysql
CLASSPATH=$ORACLE_HOME/jre:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib:.;
export CLASSPATH
export LD_LIBRARY_PATH=$ACE_ROOT/lib:$LD_LIBRARY_PATH
# oracle end

然后执行
$ source .bash_profile

使环境变量生效. /oracle 等目录应该建立好并做合适的授权.

2. 安装Orale10g
mount安装盘.由于10g无法以root安装，以前面建的oracle用户登录.执行:

$ ./runInstaller

按照提示安装即可，最后还需要以root运行两个脚本。

3. 配置TNS参数
在 /oracle/product/dbse/network/admin/ 目录下有 listener.ora 和 tnsnames.ora 两个文件，设置如下：

#listener.ora
SID_LIST_LISTENER =
  (SID_LIST =
     (SID_DESC =
      (GLOBAL_DBNAME = orcl)
      (ORACLE_HOME = /oracle/product/dbse)
      (SID_NAME = orcl)
     )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
        (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
        )
        (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.100)(PORT = 1521))
        )
    )
  )

#tnsnames.ora
ORCL =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.100)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
    )
  )

EXTPROC_CONNECTION_DATA =
  (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
        (CONNECT_DATA =
      (SID = PLSExtProc)
      (PRESENTATION = RO)
    )
  )

其中SERVICE_NAME与SID_NAME一定要和.bash_profile中的ORACLE_SID相一致，否则无法启动

4. 启动Oracle
以oracle用户登录

4.1 启动TNS监听器
$ lsnrctl start
出现如下显示，表示监听服务成功开启

4.2启动数据库
9i 之后已经没有 svrmgrl 了，所有的管理工作都通过 sqlplus 来完成：
$ sqlplus /nolog
SQL> connect system/change_on_install as sysdba
SQL> startup

出现如下显示，表示Oracle已经成功启动
ORACLE instance started.

Total System Global Area  285212672 bytes
Fixed Size                  1218968 bytes
Variable Size              88082024 bytes
Database Buffers          188743680 bytes
Redo Buffers                7168000 bytes
Database mounted.
Database opened.

4.3 自动启动与关闭

编辑 /etc/oratab ，把所有的 instance 的重启动标志设置成 'Y'，如:
orcl:/oracle/product/dbse:Y

做一个启动脚本 /etc/init.d/dbora ，如下所示:

#!/bin/sh
# description: Oracle auto start-stop script.
# chkconfig: - 20 80
#
# Set ORA_HOME to be equivalent to the $ORACLE_HOME
# from which you wish to execute dbstart and dbshut;
#
# Set ORA_OWNER to the user id of the owner of the
# Oracle database in ORA_HOME.

ORA_HOME=/oracle/product/dbse
ORA_OWNER=oracle
if [ ! -f $ORA_HOME/bin/dbstart ]
then
echo "Oracle startup: cannot start"
exit
fi
case "$1" in
'start')

# Start the Oracle databases:
# The following command assumes that the oracle login
# will not prompt the user for any values

su - $ORA_OWNER -c $ORA_HOME/bin/dbstart
su - $ORA_OWNER -c "$ORA_HOME/bin/lsnrctl start"
;;
'stop')

# Stop the Oracle databases:
# The following command assumes that the oracle login
# will not prompt the user for any values

su - $ORA_OWNER -c "$ORA_HOME/bin/lsnrctl stop"
su - $ORA_OWNER -c $ORA_HOME/bin/dbshut
;;
'restart')
$0 stop
$0 start
;;
esac

赋予执行权限
chmod 750 /etc/init.d/dbora

作成以下链接:
ln -s /etc/init.d/dbora /etc/rc0.d/K10dbora
ln -s /etc/init.d/dbora /etc/rc3.d/S99dbora

执行以下命令:
chkconfig --level 345 dbora on

这样就OK了。下次开关机的时候，Oracle也会随之启动/停止。
