oracle - sqlplus 如何查找当前连接的数据库会话的详细信息

Question

我最近开始研究 oracle 数据库。通常我有许多 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

show user

获得连接的用户

 select instance_name from v$instance

在 sqlplus 中获取实例或设置

set sqlprompt "_USER'@'_CONNECT_IDENTIFIER> "

Answer 2

我知道这是一个老问题，但我确实尝试了上述所有答案，但在我的情况下没有用。最终帮助我的是

SHOW PARAMETER instance_name

Answer 3

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

&

select instance_name from v$instance;

会给你实例名称。您还可以使用select * from global_name;来查看实例的全局名称。

Answer 4

看看这个(c) Tanel Poder。您可以从您的 glogin.sql 运行它（因此这些设置将在您每次连接时更新，或者只是手动运行它。注意host title命令 - 它使用会话信息更改您的 sql*plus 控制台窗口标题 - 对于同时打开的多个窗口非常有用.

Answer 5

尝试：

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

看到您的评论后，您可以：

SELECT * FROM global_name;

Answer 6

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

Answer 7

我们可以从以下查询中获取会话的详细信息和状态：

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'
