1、查看当前open用户

select username,account_status,expiry_date,profile from dba_users;

2、查看目前的密码过期策略

select * from dba_profiles s where s.profile='DEFAULT' and resource_name='PASSWORD_LIFE_TIME';

3、修改密码过期策略

alter profile default limit password_life_time unlimited;

04、过期的账户，重置密码后期不会再过期

$sqlplus / as sysdba

alter user smsc identified by <原来的密码> ----不用换新密码

杀掉进程：
ps -ef | grep LOCAL=NO | grep -v grep | awk '{print $2}'
ps -ef | grep LOCAL=NO | grep -v grep | awk '{print $2}' | xargs kill -9
ps -ef | grep LOCAL=NO | grep -v grep | awk '{print $2}'
ps -ef | grep LOCAL=NO
删除不掉，还是有进程 ：
sqlplus
select sid, serial# from v$session where username ='BIP';
SID SERIAL#
---------- ----------
810 3
1099 3

alter system kill session '810,3';
alter system kill session '1099,3';

unzip 压缩包 -d 目标地（目标地由此目录则会覆盖）

导入导出：
create directory DB_BACKUP as '/home/oracle/backup';
select * from dba_directories;
expdp directory=BACKUP schemas=DVUSER_BDS,BIP,ETLUSER dumpfile=bdb_20170623.dmp logfile=bdb_20170623.log compression=all
impdp directory=BACKUP schemas=DVUSER_BDS,BIP,ETLUSER dumpfile=bdb_20170623.dmp logfile=imp_bdb_20170623.log

ALTER PROFILE DEFAULT LIMIT
FAILED_LOGIN_ATTEMPTS 10
PASSWORD_REUSE_MAX unlimited
PASSWORD_REUSE_TIME unlimited
PASSWORD_LOCK_TIME 5/1440
password_verify_function null
password_life_time unlimited;

PASSWORD_REUSE_TIME 密码不能重用前的天数
PASSWORD_REUSE_TIME 密码被重用之前密码改变的次数

alter profile default limit FAILED_LOGIN_ATTEMPTS unlimited;

SQL> ALTER PROFILE DEFAULT LIMIT PASSWORD_REUSE_TIME UNLIMITED;

SQL> ALTER PROFILE DEFAULT LIMIT PASSWORD_REUSE_MAX UNLIMITED;

SQL> ALTER PROFILE DEFAULT LIMIT password_verify_function null;

设置密码永不过期：
alter profile default limit password_life_time unlimited;

建表空间、用户、权限
create tablespace developer datafile '/oradata/TSDB/developer01.dbf' size 1G autoextend on;
create user tsdev identified by tsdev default tablespace developer;
drop user ntp1 cascade;
grant CONNECT to TSBASE;
grant RESOURCE to TSBASE;
grant EXECUTE on SYS.DBMS_LOCK to TSBASE;
grant CREATE PROCEDURE to TSBASE;
grant CREATE VIEW to TSBASE;
grant CREATE SYNONYM to TSBASE;
grant CREATE MATERIALIZED VIEW to NTP1; 物化视图
grant alert session to fis;
grant create database link to tsdeal;
grant unlimited tablespace to monitor;

create user ods identified by ods;
create user tsdev identified by tsdev default tablespace developer;

删除表空间：

drop tablespace CAE_COREDATA including contents and datafiles cascade onstraints;
drop tablespace CAE_COREINDX including contents and datafiles;

查看实例名：
select instance_name from v$instance;
select name from v$database;
select status from v$instance;

添加新的数据文件
alter tablespace temp add tempfile '/oradata/XSWAPDB/temp02.dbf' size 1G autoextend on ;
alter tablespace UNDOTBS1 add datafile '/oradata/rmbtbdb/undotbs02.dbf ' size 100M autoextend on;
alter tablespace temp add tempfile '+DATADG' size 10M autoextend on ;
alter tablespace TS_REPO_DATA add datafile '+DATADG' size 100M autoextend on;
/oradata/basedb/monitorspace01.dbf
alter tablespace MONITORSPACE add datafile '/oradata/basedb/monitorspace02.dbf' size 100M autoextend on ;
offine原有错误的数据文件
alter database tempfile'/oraapp/oracle/oradata/XSWAPDB/temp01.dbf' offline;

删除原有错误的数据文件
alter database tempfile'/oraapp/oracle/oradata/XSWAPDB/temp01.dbf' drop;

查看字符集：
select * from nls_database_parameters;

改密码：
alter user TSDEV identified by Stsdev_sjqy1;

修改服务名：
alter system set service_name='tsdbsvc,TSDB';

解锁用户：
select username,ACCOUNT_STATUS, LOCK_DATE, DEFAULT_TABLESPACE,TEMPORARY_TABLESPACE, PROFILE, CREATED from dba_users order by username;
select username from dba_users;
alter user 用户 account unlock;
alter user 用户 account lock；

查看用户查看表空间：
set linesize 2000
