一、摘要

查看目前正在running的并发程式。

再确认并发程式运行的时间较长的程式，通过监控查看运行时间较长的并发程式。

通过v$session or v$session_longops查看当前session的sql和wait event。

 

二、具体SQL

1. 查看目前在运行中的并发程式

Looking on how to check long running concurrent request in Oracle Apps 11i or R12? Here’s the overview of the SQL query script to detect the session information of each program.

First you need to get the listing of running concurrent request in Oracle Apps 11i or R12. You can use the SQL query script as below to obtain the list of running request.

/* 查看目前运行的并发程式 */
  SELECT   a.request_id,
           a.oracle_process_id "SPID",
           frt.responsibility_name,
              c.concurrent_program_name
           || ': '
           || ctl.user_concurrent_program_name,
           a.description,
           a.ARGUMENT_TEXT,
           b.node_name,
           b.db_instance,
           a.logfile_name,
           a.logfile_node_name,
           a.outfile_name,
           q.concurrent_queue_name,
           a.phase_code,
           a.status_code,
           a.completion_text,
           actual_start_date,
           actual_completion_date,
           fu.user_name,
           (NVL (actual_completion_date, SYSDATE) - actual_start_date) * 1440
              mins,
           (SELECT   AVG(NVL (a2.actual_completion_date - a2.actual_start_date,
                              0))
                     * 1440
                        avg_run_time
              FROM   APPLSYS.fnd_Concurrent_requests a2,
                     APPLSYS.fnd_concurrent_programs c2
             WHERE       c2.concurrent_program_id = c.concurrent_program_id
                     AND a2.concurrent_program_id = c2.concurrent_program_id
                     AND a2.program_application_id = c2.application_id
                     AND a2.phase_code || '' = 'C')
              avg_mins,
           ROUND ( (actual_completion_date - requested_start_date), 2) * 24
              duration_in_hours
    FROM   APPLSYS.fnd_Concurrent_requests a,
           APPLSYS.fnd_concurrent_processes b,
           applsys.fnd_concurrent_queues q,
           APPLSYS.fnd_concurrent_programs c,
           APPLSYS.fnd_concurrent_programs_tl ctl,
           apps.fnd_user fu,
           apps.FND_RESPONSIBILITY_TL frt
   WHERE       a.controlling_manager = b.concurrent_process_id
           AND a.concurrent_program_id = c.concurrent_program_id
           AND a.program_application_id = c.application_id
           AND a.phase_code = 'R'
           AND a.status_code = 'R'
           AND b.queue_application_id = q.application_id
           AND b.concurrent_queue_id = q.concurrent_queue_id
           AND ctl.concurrent_program_id = c.concurrent_program_id
           AND a.requested_by = fu.user_id
           AND a.responsibility_id = frt.responsibility_id
ORDER BY   a.actual_start_date DESC

 

2. 查看并发程式对应的session

Based on the SPID associated to each running request, query the v$session or v$session_longops table to see what is the request id doing in the backend.

/* 查看并发程式对应的session */
  SELECT   b.sid,
           b.serial#,
           a.spid,
           b.program,
           b.osuser,
           b.machine,
           b.type,
           b.event,
           b.action,
           b.p1text,
           b.p2text,
           b.p3text,
           b.state,
           c.sql_text,
           b.logon_time
    FROM   v$process a, v$session b, v$sqltext c
   WHERE       a.addr = b.paddr
           AND b.sql_hash_value = c.hash_value
           AND b.STATUS = 'ACTIVE'
           AND a.spid = '11696'
ORDER BY   a.spid, c.piece

注意：Replace v$session with gv$session if the database is running on RAC environment. Enable or set trace if you wish to know more details on the session.
