怎样查看oracle当前的连接数呢？只需要用下面的SQL语句查询一下就可以了。
select * from v$session where username is not null
select username,count(username) from v$session where username is not null group by username #查看不同用户的连接数
select count(*) from v$session #连接数
Select count(*) from v$session where status=’ACTIVE’ #并发连接数
show parameter processes #最大连接
alter system set processes = value scope = spfile;重启数据库 #修改连接
/home/oracle9i/app/oracle9i/dbs/init.ora
/home/oracle9i/app/oracle9i/dbs/spfilexxx.ora ## open_cursor
