Configuration of oracle19c under alicloud lightweight application server linux-centos7

Initial environment ： Alicloud lightweight application server has been installed Oracle19c
Specific goals ： To configure Oracle Database 19c

First step ： Switch to Oracle Command line

1. modify root User password , Remember this step , Otherwise you will regret .
Carry out orders passwd , Type twice 123456, That's all right. .

2. Switch to oracle Under the user , Carry out orders su - oracle：

3. Check the listening status , Carry out orders lsnrctl status：

Monitor start , Carry out orders lsnrctl start：

Monitor off , Carry out orders lsnrctl stop;

4. Sign in oracle database , Carry out orders sqlplus / as sysdba.

The second step ： Create new users and tablespaces

1. Boot instance , Carry out orders startup：

Close instance , Carry out orders shutdown;

tips： If startup Report a mistake later ORA-01012: not logged on;

sqlplus / as sysdba
shutdonwn abort

2. Create a temporary table space ：

-- Query the absolute path of the temporary tablespace file . If necessary , You can write an absolute path through a query . It's usually used ${ORACLE_HOME} That's all right.  
select name from v$tempfile;  
create temporary tablespace TESTLEAF_TEMP tempfile '${ORACLE_HOME}\oradata\TESTLEAF_TEMP.bdf' size 100m reuse autoextend on next 20m maxsize unlimited; 

3. Create formal tablespaces ：

-- Query the absolute path of user tablespace file ：
select name from v$datafile;
create tablespace TESTLEAF datafile '${ORACLE_HOME}\oradata\TESTLEAF.dbf' size 100M reuse autoextend on next 40M maxsize unlimited default storage(initial 128k next 128k minextents 2 maxextents unlimited);

4. Create users and passwords , Specify the temporary tablespace and tablespace created above （ When creating a user, the user name should be C## At the beginning , Prevent prompting that the user name is invalid ）：

create user C##TESTLEAF identified by 123456 default tablespace TESTLEAF temporary tablespace TESTLEAF_TEMP;

tips：
Compared with oracle11g,oracle19c One more. CDB and PDB The concept of （ from 12C Begin to appear ）
https://www.it610.com/article/1280868824853266432.htm

5. Modify the user name
Query the number of the user name to be modified ：

select user#,name from user$;

（ Take the corresponding user#, here user# be equal to 113）
Change user name ：

update user$ set name='TESTLEAF' where user#=113;

6. solve Oracle After modifying the user name , Change the user password again , Will be submitted to the ‘ The user could not be found ’ The problem of ：

ALTER SYSTEM FLUSH SHARED_POOL;

7. Change the password corresponding to the user ：

ALTER USER TESTLEAF IDENTIFIED BY 123456;

8. User empowerment ：

grant dba to TESTLEAF;
grant connect,resource to TESTLEAF;
grant select any table to TESTLEAF;
grant delete any table to TESTLEAF;
grant update any table to TESTLEAF;
grant insert any table to TESTLEAF;
# Permissions to manipulate tablespaces 
grant unlimited tablespace to TESTLEAF;

9. View all user permissions ：

select * from dba_sys_privs where grantee = 'TESTLEAF';
select * from dba_role_privs where grantee = 'TESTLEAF';

The third step ： Switching users

1. Switch to the user you just created （ user name + password ）：

conn TESTLEAF/123456;

2. Check the current user ：

show user;

Step four ： Create some tables under the current user

1. Create table Customers

CREATE TABLE Customers
(
  cust_id      char(10)  NOT NULL ,
  cust_name    char(50)  NOT NULL ,
  cust_address char(50)  NULL ,
  cust_city    char(50)  NULL ,
  cust_state   char(5)   NULL ,
  cust_zip     char(10)  NULL ,
  cust_country char(50)  NULL ,
  cust_contact char(50)  NULL ,
  cust_email   char(255) NULL 
);

2. Create table OrderItems

CREATE TABLE OrderItems
(
  order_num  int          NOT NULL ,
  order_item int          NOT NULL ,
  prod_id    char(10)     NOT NULL ,
  quantity   int          NOT NULL ,
  item_price decimal(8,2) NOT NULL 
);

3. Create table Orders

CREATE TABLE Orders
(
  order_num  int      NOT NULL ,
  order_date date     NOT NULL ,
  cust_id    char(10) NOT NULL 
);

4. Create table Products

CREATE TABLE Products
(
  prod_id    char(10)      NOT NULL ,
  vend_id    char(10)      NOT NULL ,
  prod_name  char(255)     NOT NULL ,
  prod_price decimal(8,2)  NOT NULL ,
  prod_desc  varchar(1000) NULL 
);

5. Create table Vendors

CREATE TABLE Vendors
(
  vend_id      char(10) NOT NULL ,
  vend_name    char(50) NOT NULL ,
  vend_address char(50) NULL ,
  vend_city    char(50) NULL ,
  vend_state   char(5)  NULL ,
  vend_zip     char(10) NULL ,
  vend_country char(50) NULL 
);

6. Define the primary key

ALTER TABLE Customers ADD CONSTRAINT PK_Customers PRIMARY KEY (cust_id);
ALTER TABLE OrderItems ADD CONSTRAINT PK_OrderItems PRIMARY KEY (order_num, order_item);
ALTER TABLE Orders ADD CONSTRAINT PK_Orders PRIMARY KEY (order_num);
ALTER TABLE Products ADD CONSTRAINT PK_Products PRIMARY KEY (prod_id);
ALTER TABLE Vendors ADD CONSTRAINT PK_Vendors PRIMARY KEY (vend_id);

7. Defining foreign keys

ALTER TABLE OrderItems
ADD CONSTRAINT FK_OrderItems_Orders FOREIGN KEY (order_num) REFERENCES Orders (order_num);
ALTER TABLE OrderItems
ADD CONSTRAINT FK_OrderItems_Products FOREIGN KEY (prod_id) REFERENCES Products (prod_id);
ALTER TABLE Orders
ADD CONSTRAINT FK_Orders_Customers FOREIGN KEY (cust_id) REFERENCES Customers (cust_id);
ALTER TABLE Products
ADD CONSTRAINT FK_Products_Vendors FOREIGN KEY (vend_id) REFERENCES Vendors (vend_id);
