Oracle DBMS_应用程序_INFO.SET_客户端_INFO不工作

我需要设置client_info值以区分不同的客户端

这些是我正在运行以测试的脚本

步骤1：系统模式

ALTER SYSTEM FLUSH SHARED_POOL;
ALTER SYSTEM FLUSH BUFFER_CACHE;

select
    *
from
    (
        select
           a.SQL_ID
          ,a.SQL_FULLTEXT
          ,to_char( a.LAST_ACTIVE_TIME,'DD-MON-YYYY HH24:MI:SS' )                                                                                as LAST_ACTIVE_TIME

          ,b.CLIENT_INFO
          ,a.MODULE
          ,a.ACTION
        from
            GV$SQL a
        left outer join GV$SESSION b
        on
            (
                b.SQL_ID = a.SQL_ID
            )
        where
            a.EXECUTIONS != 0
    )
    c
where
    c.MODULE like '%CHECK%'
order by
    c.LAST_ACTIVE_TIME desc ;

ALTER SYSTEM FLUSH SHARED_POOL;
ALTER SYSTEM FLUSH BUFFER_CACHE;

SELECT
    a.SQL_ID
   ,a.CLIENT_INFO
   ,a.MODULE
   ,a.ACTION
   ,a.SCHEMANAME
   ,a.USERNAME
FROM
   V$SESSION a
WHERE
    a.MODULE = 'CHECK';

步骤2：人力资源模式

EXEC DBMS_APPLICATION_INFO.SET_CLIENT_INFO(UTL_INADDR.GET_HOST_NAME );
EXEC DBMS_APPLICATION_INFO.SET_MODULE( 'CHECK','select' );

select                                      
    a.FIRST_NAME || ' ' || LAST_NAME AS FULL_NAME

where                                       
    a.DEPARTMENT_ID = '40'
;

EXEC DBMS_APPLICATION_INFO.SET_CLIENT_INFO(UTL_INADDR.GET_HOST_NAME );
EXEC DBMS_APPLICATION_INFO.SET_MODULE( 'CHECK','select' );

步骤3：系统模式

ALTER SYSTEM FLUSH SHARED_POOL;
ALTER SYSTEM FLUSH BUFFER_CACHE;

select
    *
from
    (
        select
           a.SQL_ID
          ,a.SQL_FULLTEXT
          ,to_char( a.LAST_ACTIVE_TIME,'DD-MON-YYYY HH24:MI:SS' )                                                                                as LAST_ACTIVE_TIME
          ,a.SERVICE
          ,b.SCHEMANAME
          ,b.CLIENT_INFO
          ,a.MODULE
          ,a.ACTION
        from
            GV$SQL a
        left outer join GV$SESSION b
        on
            (
                b.SQL_ID = a.SQL_ID
            )
        where
            a.EXECUTIONS != 0
    )
    c
where
    c.MODULE like '%CHECK%'
order by
    c.LAST_ACTIVE_TIME desc ;

ALTER SYSTEM FLUSH SHARED_POOL;
ALTER SYSTEM FLUSH BUFFER_CACHE;

SELECT
    a.SQL_ID
   ,a.CLIENT_INFO
   ,a.MODULE
   ,a.ACTION
   ,a.SCHEMANAME
   ,a.USERNAME
FROM
   V$SESSION a
WHERE
    a.MODULE = 'CHECK';

模块和操作列正在获取值，但客户端信息没有显示任何内容

我有什么遗漏吗

更新： 我也试过，但运气不好

EXEC DBMS_APPLICATION_INFO.SET_CLIENT_INFO( SYS_CONTEXT('userenv','ip_address') );
EXEC DBMS_APPLICATION_INFO.SET_CLIENT_INFO( '10.10.10.10' );

SET\u CLIENT\u INFO

与会话相关，而不是与单个SQL语句相关

这样做

您是否为“步骤3”打开了新连接？@WernfriedDomscheit No。这些操作是在SQL developer上的两个并行会话中完成的。您是否从中获得了任何信息：

SELECT*from V$SESSION，其中CLIENT_INFO不为NULL

只需查看

V$SESSION，其中客户端信息不为空

。不要混淆SQL和PL/SQL。

SET\u CLIENT\u INFO

与会话相关，而不是与单个SQL语句相关。你想达到什么目标？尝试

SELECT*FROM V$SESSION，其中USERNAME={用于连接的用户}
