grant unlimited tablespace to ocs;

 

------创建表空间

CREATE TABLESPACE ocsdata DATAFILE '/home/oracle/oradata/ocs/ocsdata01.dbf' SIZE 5000M UNIFORM SIZE 128k;

 查看用户和默认表空间的关系。   
  select   username,default_tablespace   from   dba_users;

用户默认表空间

 alter user ocs default tablespace ocsdata

 

定时器不能用可以试试

ALTER SYSTEM SET job_queue_processes = 10;

 

 

--连接数查看

select username,count(0) from v$session group by username;

--查看链接进程

select sid,serial# from v$session where username='OCS_GXYZ';

备注此处执行多遍
