Oracle高级操作：启停服务，开启PDB，创建表空间用户导入导出用户数据等

sqlplus  system/orcl_123456@orcl   //sqlplus连接

select name from v$database;    //查询当前数据库名

select instance_name from v$instance; // 查询当前数据库实例名

//创建临时表空间

CREATE TEMPORARY TABLESPACE OX_TEMP TEMPFILE '/opt/oracle/oradata/orcl/OX_TEMP.DBF'
SIZE 64M
AUTOEXTEND ON
NEXT 64M MAXSIZE UNLIMITED
EXTENT MANAGEMENT LOCAL;

//创建数据表空间

CREATE TABLESPACE OX_DATA
LOGGING
DATAFILE '/opt/oracle/oradata/orcl/OX_DATA.DBF'

AUTOEXTEND ON
NEXT 64M MAXSIZE UNLIMITED
EXTENT MANAGEMENT LOCAL;

//创建用户（方案） 并指定表空间

CREATE USER OX IDENTIFIED BY ox_123456
ACCOUNT UNLOCK
DEFAULT TABLESPACE OX_DATA
TEMPORARY TABLESPACE OX_TEMP;

//给用户授权
GRANT CONNECT,RESOURCE TO OX;//  把connect,resource权限授予用户
GRANT DBA TO OX;    //把 dba权限授予给用户

---一般用户登录---
sqlplus  C##DBADMIN/orcl_admin@orcl;

sqlplus ox/ox_123456@ORCLPDB;

conn  C##DBADMIN/orcl_admin@orcl;
--打开PDB数据库--

sqlplus / as sysdba

#查看PDB数据状态

select con_id,name,open_mode from v$pdbs;

alter pluggable database ORCLPDB open;

alter session set container=ORCLPDB;

commit;

--sys dba登陆 开启服务---
# su - oracle
$ lsnrctl status   检查oracle监听器运行状态
$ lsnrctl start / lsnrctl stop

sqlplus / as sysdba  

>startup  //开启服务   >shutdown immediate; //关闭服务

--oracle 12c 开启pdb数据库-- 

select CDB from v$database;

show con_name;

select con_id, dbid, guid, name , open_mode from v$pdbs;

alter pluggable database ORCLPDB open; 
alter pluggable database all open;
#alter pluggable database PDBORCL close;

jdbc连接oracle12的数据库需要具备的条件:
 1、监听成功启用,且tnsping通过(OK (30 毫秒);
 2、tnsnames.ora配置正确(连接pdb数据库,注意添加pdb服务项,具体如何配置查看[准备阶段]);
 3、 监听连带的相应数据库成功开启;
 4、Jdbc连接字符串迭代更新为”jdbc:oracle:thin:@192.168.75.131:1521/pdborcl”而非" jdbc:oracle:thin:@192.168.75.131:1521:pdborcl"

--一个触发器--
conn / as sysdba

CREATE TRIGGER open_all_pdbs
AFTER STARTUP
ON DATABASE
BEGIN
EXECUTE IMMEDIATE 'alter pluggable database all open';
END
open_all_pdbs;

--Oracle数据库导出--
exp ox/ox_pwd@ox file=/home/oracle/ox_db.dmp owner=ox rows=n

exp ox/ox_123456@orclpdb  file=/home/oracle/db_bak/ox_db.dmp owner=ox rows=n   //仅owner=ox导出结构

 

---重点-----导出owner=ox所有数据对象

exp ox/ox_pwd@ox buffer=10240 file=/home/oracle/ox_db_20190417.dmp log=/home/oracle/ox_db_20190417.log owner=ox   //导出owner=ox所有数据对象

--Oracle数据库导入--
sqlplus / as sysdba

select owner, table_name from dba_tables where owner='OX';

alter session set container=orclpdb;

imp ox/ox_123456@orclpdb buffer=10240 file=ox_db.dmp full=y ignore=y;

imp ox/ox_123456@orclpdb buffer=10240 file=ox_db_20190417.dmp full=y ignore=y;  

 

----重点----将fromuser=OX用户的所有数据对象导入到touser=OX---

imp SYSTEM/oracle@orclpdb buffer=102400 file=ox_db_20190417.dmp fromuser=OX touser=OX ignore=y;  （不能使用full=y） //将fromuser=OX用户的所有数据对象导入到touser=OX

--删除方案（删除OX2用户及OX2的所有数据）---

drop user OX2 cascade;
