新建数据库
eg:实例名:forumbank
cmd管理员:
mkdir D:\app\Administrator\admin\forumbank\adump
mkdir D:\app\Administrator\admin\forumbank\dpdump
mkdir D:\app\Administrator\admin\forumbank\pfile
mkdir D:\app\Administrator\cfgtoollogs\dbca\forumbank
mkdir D:\app\Administrator\flash_recovery_area
mkdir D:\app\Administrator\oradata\forumbank
set ORACLE_SID=forumbank
一个实例一个数据库
ORAPWD FILE=“D:\app\yourInstallName\product\11.2.0\dbhome_1\database\PWDforumbank.ORA” PASSWORD=forumbank123
修改pfile
Oradim -NEW -SID forumbank -SYSPWD 123 -STARTMODE auto -PFILE “D:\app\Administrator\admin\forumbank\pfile\initforumbank.ora”
SQLPLUS /NOLOG
CONNECT SYS/forumbank123 as SYSDBA
STARTUP NOMOUNT PFILE=“D:\app\Administrator\admin\forumbank\pfile\initforumbank.ora”

create spfile=’D:\app\yourInstallName\product\11.2.0\dbhome_1\database\spfileforumbank.ora’ FROM pfile=’D:\app\Administrator\admin\forumbank\pfile\initforumbank.ora’;
spfile路径命名规范:database下 spfile+实例名
(SID_DESC =
(GLOBAL_DBNAME = forumbank)
(ORACLE_HOME = D:\app\yourInstallName\product\11.2.0\dbhome_1)
(SID_NAME = forumbank)
)
listener.ora :添加在SID_LIST里面 配置监听
cba =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST =127.0.0.1)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME =forumbank)
)
)
tnsnames.ora配置连接标志符
重新启动监听,使其包含新的实例
conn sys/forumbank123@cba as sysdba
总结:
oracle版本为11.2
yourInstallName 为你的安装目录app下的数据库目录(包含product)的名称
注意实例与数据库第一次(无 nomount)和以后(有)启动 (就直接startup pfile路径)的差异
数据库名称限定八个字符 bankdb
如果数据库创建第一行失败:1.检查pfile里的初始化文件的dbname 与你的代码是否一致 2.如果改正后还出错(包含控制文件说明是初始化文件的问题),就删掉日志和 D:\app\Administrator\oradata下新的实例文件夹,再用命令ORADIM –DELETE –SID forumbank
删掉你的 新实例,改好初始化文件后重新建一个实例,重新走一遍就好
jdbc java连接代码
import java.sql.*; public class ConnOracle { public static void main(String[] args){ Connection con; Statement sql; ResultSet rs; try{ Class.forName("oracle.jdbc.driver.OracleDriver"); }catch (ClassNotFoundException e){ System.out.print(e); } try{ String url = "jdbc:Oracle:thin:@127.0.0.1:1521:forumbank";//@ip:端口:实例名 con = DriverManager.getConnection(url, "user1", "forumbank123"); sql=con.createStatement(); rs=sql.executeQuery("SELECT * FROM USER_IOT WHERE userid = '2015000000'"); while(rs.next()){ String userid=rs.getString(1);//列索引,从1开始 String pwd=rs.getString(2); System.out.printf("%-12s",userid);//-用来保证前后间隔,不会自动去掉尾部多余长度 System.out.printf("%-4s",pwd); } con.close(); }catch (SQLException e){ System.out.println(e); } } }
连接前请打开数据库,并确保已创建表及插入相关数据。
用户名请用sys赋予一个角色权限与密码,重新登录,此处用user1。连接jar包用的是:classes12.jar,当然你有ojdbc6.jar是最好。安装了oracle自会有classes12.jar,路径:D:\app\ yourInstallName\product\11.2.0\dbhome_1\oui\jlib
最后:相关文件存放路径:
initforumbank.ora : D:\app\Administrator\admin\forumbank\pfile
listener.ora: D:\app\yourInstallName\product\11.2.0\dbhome_1\NETWORK\ADMIN
tnsnames.ora: D:\app\yourInstallName\product\11.2.0\dbhome_1\NETWORK\ADMIN
