oracle数据库
oracle数据库创建表空间

--1：创建临时表空间create temporary tablespace givaName_temp tempfile 'F:\orcal\orcalan\hsj\givaName_temp.dbf' size 50m autoextend on next 50m maxsize unlimited extent management local;  --2：创建数据表空间create tablespace givaName logging datafile 'F:\orcal\orcalan\hsj\givaName.dbf' size 50m autoextend on next 50m maxsize unlimited extent management local;  --第3步：创建用户并指定表空间create user givaName identified by 密码 default tablespace givaName temporary tablespace givaName_temp;  --第4步：给用户授予权限grant connect,resource,dba to givaName ;grant grant create  database link to givaName--查询数据库中的表空间名称及大小select t.tablespace_name, round(sum(bytes/(1024*1024)),0) ts_sizefrom dba_tablespaces t, dba_data_files dwhere t.tablespace_name = d.tablespace_namegroup by t.tablespace_name; 

cmd命令导入及导出oracle数据库

cmd命令导出本地数据exp username/password file=e:/test.dmp导出服务器数据exp username/password@10.4.24.99:1521/orcl file=e:/test.dmp导入imp usename/password file=e:/test.dmp fromuser=admin touser=test ignore=y 

oracle数据库解除死锁
oracle时常发生死锁，可以用下方语句解除

--查询死锁进程SELECT s.username,l.OBJECT_ID,l.SESSION_ID,s.SERIAL#,l.ORACLE_USERNAME,l.OS_USER_NAME,l.PROCESS FROM V$LOCKED_OBJECT l,V$SESSION S WHERE l.SESSION_ID=S.SID;--alter system kill session 'SESSION_ID,SERIAL#'
