1,忘记sys密码
打开CMD命令窗口,执行以下操作:
1,SQLPLUS /NOLOG;
2,
3,CONNECT / AS SYSDBA
4,
5,ALTER USER SYS IDENTIFIED BY 新密码
6,
7,ALTER USER SYSTEM IDENTIFIED BY 新密码
8,
2,以sys账号登陆
建立用户表空间,索引表空间,创建用户,授权,分配配额:
--创建用户表空间--基础区
CREATE TABLESPACE TABLESPACE_NAME DATAFILE
‘d:/oracledata/TABLESPACE_NAME01.dbf‘ SIZE 100M AUTOEXTEND ON NEXT 10M MAXSIZE UNLIMITED;
--创建索引表空间--基础区
CREATE TABLESPACE TPPAML_BSE_IDX DATAFILE
‘d:/oracledata/TABLESPACE_NAME_IDX01.dbf‘ SIZE 100M AUTOEXTEND ON NEXT 10M MAXSIZE UNLIMITED;--创建用户
CREATE USER USERNAME
IDENTIFIED BY "USER_PASSWORD"
DEFAULT TABLESPACE TPPAML_BSE;-- 给用户TPPAML授权
GRANT CONNECT TO USERNAME;
GRANT RESOURCE TO USERNAME;
GRANT CREATE TABLE TO USERNAME; --建表权限
GRANT CREATE ALL TABLE TO USERNAME; --在所有表空间下建表权限(考虑是否需要)--1 System Privilege for username
GRANT UNLIMITED TABLESPACE TO USERNAME;-- 1 Tablespace Quota for username 无限制的空间限额
ALTER USER TPPAML QUOTA UNLIMITED ON TPPAML_BSE;
3,用新建的账号登陆建表即可
CREATE TABLE TABLE_NAME
(
ID VARCHAR2(32) NOT NULL,
NAME VARCHAR2(32)
)
TABLESPACE TABLESPACE_NAME
PCTFREE 10
INITRANS 1
MAXTRANS 255
STORAGE
(
INITIAL 1M
NEXT 1M
MINEXTENTS 1
MAXEXTENTS UNLIMITED
PCTINCREASE 0
);
ALTER TABLE TABLE_NAME
ADD CONSTRAINT PRIMART_TABLE PRIMARY KEY (ID) --外键
USING INDEX
TABLESPACE TABLESPACE_NAME
PCTFREE 10
INITRANS 2
MAXTRANS 255
STORAGE
(
INITIAL 1M
NEXT 1M
MINEXTENTS 1
MAXEXTENTS UNLIMITED
PCTINCREASE 0
);
