本文主要是介绍oracle11安装及使用，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
安装oracle11
官网下载地址 Oracle Database 11g Release 2 for Microsoft Windows (x64)
官网下载慢可访问我的资源
也可以网盘获取

提取码：z3na
上传安装包到服务器
在指定目录下创建文件夹installfile，我是在/newdisk/oracle/installfile，将安装文件上传到该文件夹
禁用防火墙
systemctl stop firewalld.servicesystemctl disable firewalld.service
安装依赖包
yum -y install binutils compat-libcap1 compat-libstdc++-33 compat-libstdc++-33*i686 compat-libstdc++-33*.devel compat-libstdc++-33 compat-libstdc++-33*.devel gcc gcc-c++ glibc glibc*.i686 glibc-devel glibc-devel*.i686 ksh libaio libaio*.i686 libaio-devel libaio-devel*.devel libgcc libgcc*.i686 libstdc++ libstdc++*.i686 libstdc++-devel libstdc++-devel*.devel libXi libXi*.i686 libXtst libXtst*.i686 make sysstat unixODBC unixODBC*.i686 unixODBC-devel unixODBC-devel*.i686
验证依赖包
rpm -q binutils compat-libcap1 compat-libstdc++-33 gcc gcc-c++ glibc glibc-devel ksh libaio libaio-devel libgcc libstdc++ libstdc++-devel libXi libXtst make sysstat unixODBC unixODBC-devel
创建orcale用户
[root@localhost installfile]# groupadd -g 502 oinstall
[root@localhost installfile]# groupadd -g 503 dba
[root@localhost installfile]# groupadd -g 504 oper
[root@localhost installfile]# groupadd -g 505 asmadmin
[root@localhost oracle]# sudo useradd -u 502 -g oinstall -G oinstall,dba,asmadmin,oper -s /bin/bash -m oracle
[root@localhost oracle]# passwd oracle
Changing password for user oracle.
New password:
BAD PASSWORD: The password is shorter than 8 characters
Retype new password:
passwd: all authentication tokens updated successfully.
[root@localhost oracle]#
创建oradata目录，解压oracle安装包
mkdir /oradata将/newdisk/oracle/oradatainstallfile/文件夹下的压缩包剪切到/oradata下面
drwxr-xr-x. 2 root root 98 Feb 27 00:31 installfile
drwxr-xr-x. 2 root root 6 Feb 27 02:03 oradata
[root@localhost oracle]# cp installfile/* oradata/
[root@localhost oracle]# ls oradata/
p13390677_112040_Linux-x86-64_1of7.zip p13390677_112040_Linux-x86-64_2of7.zip
[root@localhost oracle]#
将/newdisk/oracle/oradata上的目录内的所有文件和文件夹的归属都修改为oracle用户
chown -R oracle:oinstall /newdisk/oracle/oradata登录oracle用户将两个压缩文件解压
[root@localhost oradata]# su oracle
[oracle@localhost oradata]$ unzip p13390677_112040_Linux-x86-64_1of7.zip
[oracle@localhost oradata]$ unzip p13390677_112040_Linux-x86-64_2of7.zip会多一个database文件夹
root用户下修改系统配置参数
[oracle@localhost oradata]$ su root
Password:
[root@localhost oradata]# vim /etc/security/limits.conf#在最后加上下面配置oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
oracle soft stack 10240
配置oracle安装目录
用oracle用户并创建安装目录
[root@localhost oradata]# su oracle
[oracle@localhost oradata]$ pwd
/newdisk/oracle/oradata
[oracle@localhost oradata]$ mkdir -p /newdisk/oracle/oradata/oracle11g
配置环境变量
用oracle用户
[oracle@localhost /]$ cd
[oracle@localhost ~]$ vim .bash_profile
在最后一行输入下面的命令：
#这边地址根据安装目录定
export ORACLE_BASE=/newdisk/oracle/oradata/oracle11g
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0.3/dbhome_1
export ORACLE_SID=prod
export NLS_LANG=.AL32UTF8
export PATH=${PATH}:${ORACLE_HOME}/bin:$ORACLE_HOME/lib64
使环境变量生效
[oracle@localhost ~]$ source .bash_profile
修改安装配置文件
拷贝安装文件db_install.rsp到/newdisk/oracle/oradata/目录下
[oracle@localhost oradata]$ cp database/response/db_install.rsp /newdisk/oracle/oradata/
[oracle@localhost oradata]$ ll
total 2487228
drwxr-xr-x. 7 oracle oinstall 136 Aug 26 2013 database
-rw-r--r--. 1 oracle oinstall 25116 Feb 27 03:31 db_install.rsp
drwxr-xr-x. 2 oracle oinstall 6 Feb 27 03:29 oracle11g
-rw-r--r--. 1 oracle oinstall 1395582860 Feb 27 02:04 p13390677_112040_Linux-x86-64_1of7.zip

编辑db_install.rsp
[oracle@localhost oradata]$ vim db_install.rsp
下面分别在文件中的对应行号内进行相应的设置
可以使用 :set number 显示行号

开始安装oracle
输入下面的命令：
进入/newdisk/oracle/oradata/database目录
执行安装命令
./runInstaller -silent -ignoreSysPrereqs -responseFile /newdisk/oracle/oradata/db_install.rsp -ignorePrereq
等待直到出现下面代码就成功了
连接oracle
sqlplus / as sysdba
正常情况会连接成功，而我出现了如下的情况
这就是虽然安装成功了，但问题可能在于sqlplus命令未能正确添加到系统路径中
所以在安装目录找sqlplus命令
[oracle@localhost database]$ find /newdisk/ -name sqlplus
/newdisk/oracle/oradata/oracle11g/product/11.2.0.3/dbhome_1/bin/sqlplus
/newdisk/oracle/oradata/oracle11g/product/11.2.0.3/dbhome_1/sqlplus
我们先打印ORACLE_HOME
发现和我们安装的目录不一样，查看~/.bash_profile文件
在打印ORACLE_BASE
发现是空，查看 ~/.bash_profile文件
发现是有值的，那就是没有刷新配置，刷新一下配置，在查看
再次连接oracle，成功
navicat连接测试
使用sys用户密码是上面设置的oracle，
oracle.install.db.config.starterdb.password.ALL=oracle
使用sys登录需要时sysdba角色，如下
卸载oracle
以root用户身份登录系统
停止所有Oracle相关进程。您可以使用以下命令来列出所有Oracle进程并停止它们（请注意，这里假设您正在使用Oracle 11g）：
ps -ef | grep oracle | grep -v grep然后，您可以使用kill命令停止每个进程。例如，如果您想要停止进程ID为1234的进程，可以使用以下命令
kill -9 1234停止监听
lsnrctl stop删除安装目录
rm -rf /newdisk/oracle/oradata/oracle11grm -rf /newdisk/oracle/oradata/oraInventory/创建用户并赋予权限
--创建用户
CREATE USER testuser IDENTIFIED BY 123456;--分配连接权限GRANT CONNECT TO testuser;-- 分配创建会话权限
GRANT CREATE SESSION TO testuser;--把所有权限都给用户
GRANT ALL PRIVILEGES TO testuser;
查询所有表空间
SELECT --B.file_name "文件名",A.TABLESPACE_NAME "表空间名",TOTAL "表空间大小",FREE "表空间剩余大小",(TOTAL - FREE) "表空间使用大小",TOTAL / (1024 * 1024 * 1024) "表空间大小(G)",FREE / (1024 * 1024 * 1024) "表空间剩余大小(G)",(TOTAL - FREE) / (1024 * 1024 * 1024) "表空间使用大小(G)",ROUND((TOTAL - FREE) / TOTAL, 4) * 100 "使用率 %"
FROM (SELECT TABLESPACE_NAME,SUM(BYTES) FREEFROM DBA_FREE_SPACEGROUP BY TABLESPACE_NAME) A,(SELECT TABLESPACE_NAME,-- file_name,SUM(BYTES) TOTALFROM DBA_DATA_FILESGROUP BY TABLESPACE_NAME/*,file_name*/) B
WHERE A.TABLESPACE_NAME = B.TABLESPACE_NAME;创建表空间
CREATE TABLESPACE 表空间名称 LOGGING DATAFILE 挂载地址 SIZE 大小 ;--举例
CREATE TABLESPACE TBS_INDEX_ITMS LOGGING DATAFILE '/export/home/oradata/TBS_INDEX_ITMS' SIZE 5120M ;删除表空间
--删除空的表空间，但是不包含物理文件
drop tablespace tablespace_name;
--删除非空表空间，但是不包含物理文件
drop tablespace tablespace_name including contents;
--删除空表空间，包含物理文件
drop tablespace tablespace_name including datafiles;
--删除非空表空间，包含物理文件
drop tablespace tablespace_name including contents and datafiles;
--如果其他表空间中的表有外键等约束关联到了本表空间中的表的字段，就要加上CASCADE CONSTRAINTS
drop tablespace tablespace_name including contents and datafiles CASCADE CONSTRAINTS;执行sql文件
