sqlplus如何查找当前连接的数据库会话的详细信息

Question

我最近开始使用oracle数据库。一般来说，我有很多sqlplus窗口打开到不同的oracle数据库。从一个sqlplus会话切换到另一个会话时，如何查看每个sqlplus会话的当前会话详细信息？任何帮助是极大的赞赏！

Answer 1

看看这个(c) Tanel Poder。您可以从glogin.sql运行它（所以这些设置会在每次连接时更新，或者手动运行。注意host title命令 - 它会更改您的sql * plus控制台窗口标题和会话信息 - 在许多窗口打开时非常有用。同时

Answer 2

select * from v$session 
where sid = to_number(substr(dbms_session.unique_session_id,1,4),'XXXX') 

Answer 3

show user 

可以连接用户

select instance_name from v$instance 

获得实例或在sqlplus设置

set sqlprompt "_USER'@'_CONNECT_IDENTIFIER> " 

Answer 4

尝试：

select * from v$session where sid = SYS_CONTEXT('USERENV','SID');

seing您的评论后，你可以这样做：

SELECT * FROM global_name; 

Answer 5

我知道这是一个老问题，但我也尝试以上所有的答案，但没有工作，在我的情况是什么最终帮了我是

SHOW PARAMETER instance_name

Answer 6

select sys_context('USERENV','INSTANCE_NAME') from dual; 

&

select instance_name from v$instance; 

会给你的实例名。 您也可以使用select * from global_name;来查看实例的全局名称。

Answer 7

我们可以从下面的查询为获得session的详细信息和状态：

select ' Sid, Serial#, Aud sid : '|| s.sid||' , '||s.serial#||' , '|| 
     s.audsid||chr(10)|| '  DB User/OS User : '||s.username|| 
     ' / '||s.osuser||chr(10)|| ' Machine - Terminal : '|| 
     s.machine||' - '|| s.terminal||chr(10)|| 
     '  OS Process Ids : '|| 
     s.process||' (Client) '||p.spid||' (Server)'|| chr(10)|| 
     ' Client Program Name : '||s.program "Session Info" 
    from v$process p,v$session s 
where p.addr = s.paddr 
    and s.sid = nvl('&SID',s.sid) 
    and nvl(s.terminal,' ') = nvl('&Terminal',nvl(s.terminal,' ')) 
    and s.process = nvl('&Process',s.process) 
    and p.spid = nvl('&spid',p.spid) 
    and s.username = nvl('&username',s.username) 
    and nvl(s.osuser,' ') = nvl('&OSUser',nvl(s.osuser,' ')) 
    and nvl(s.machine,' ') = nvl('&machine',nvl(s.machine,' ')) 
    and nvl('&SID',nvl('&TERMINAL',nvl('&PROCESS',nvl('&SPID',nvl('&USERNAME', 
     nvl('&OSUSER',nvl('&MACHINE','NO VALUES'))))))) <> 'NO VALUES'
