Oracle的安装及使用流程

Oracle的安装及使用流程

1.Win10安装Oracle10g

1.1 安装与测试

安装版本： OracleXEUniv10.2.1015.exe
步骤参考：oracleXe下载与安装

安装完成后测试是否正常

# 输入命令连接oracle
conn sys as sysdba;
# 无密码，直接按回车
# 测试连接的sql语句
select 1 from dual;

1.2 查询数据库信息

#在Oracle中
#查询数据库名
select name,dbid from v$database;或者show parameter db_name;
#查询实例名
select instance_name from v$instance;或者show parameter instance_name;
#查询数据库域名
select value from v$parameter where name='db_domain';或者show parameter domain;
#查询数据库服务器
select value from v$parameter where name='service_name';或者show parameter service;或者show parameter names;#在PL/SQL下
Oracle用户查询其他用户的表一定要使用user.table格式才能查询，每次用户名.表名嫌麻烦的话。可以使用同义词，意思将user.table访问格式改成table格式即可
#创建同义词语句格式：
create public synonym table_name for user.table_name;
public很关键词，访问权限修饰，若想某表的授权用户也能用同义词查询，必须要用public访问修饰符。
#举例说明
原本"表前缀.表名"格式才能访问select * from PAASDATA.paas_city_def;
创建同义词：create public synonym table_name for PAASDATA.paas_city_def;
可直接用表名：select * from paas_city_def;

1.3 自定义用户和表空间

执行创建命令

conn sys/root as sysdba;
# 查询实例
select instance_name from v$instance;
# 查询数据库
select name from v$datafile;
# 创建表空间
create tablespace CK_BUS_TABLE_SPACE datafile 'D:/AsiaInfo/oraclexe/oraclexe/oradata/XE/CK_BUS_TABLE_SPACE.dbf' size 200m 
autoextend on extent  management local segment space management auto;
# 查询数据库
select name from v$datafile;
# 创建用户并指定表空间
# CREATE USER 用户 IDENTIFIED BY 用户密码 DEFAULT TABLESPACE NOTIFYDB;
CREATE USER CK_BUS IDENTIFIED BY ck_bus DEFAULT TABLESPACE CK_BUS_TABLE_SPACE;
# 给用户授予dba的权限
grant dba to CK_BUS; # 查看当前数据库连接数
select count(*) from v$process;
# 查看数据库允许的最大连接数
select value from v$parameter where name = 'processes';
# 如果数据库连接数超过最大连接数，请修改最大连接数，我这里修改成了1000
alter system set processes = 1000 scope = spfile;
# 重启
shutdown immediate;
startup;

测试创建结果

# 登录账号
conn CK_BUS/ck_bus@xe;
select * from dual;

2.CentOS7安装Oracle11gR2

• 创建表空间
• 创建用户
• 给用户授权
• 查询测试
