并发处理 （ Concurrent process） 和 并发管理器（Concurrent Manager） 是R12中负责
处理批作业 或 后台作业的。 用的地方很多，所以需要多花点时间理解。

Concurrent Manager 管理的基础知识，比如 start/stop，output and logfile location 等，
前面已提及。

下面只是列出一些常用的内容，可以帮助理解concurrent manager。

=====================================================
# 如何从 concurrent request id  找到 Oracle session id (sid) ：

很多时候我们需要从 concurrent request 的request id 找到对应的
Oracle session id （sid），可以用下面的方法， 由此我们也可了解
concurrent manager 对应的 table 结构。


# 当前正在运行的 concurrent request：

select request_id, controlling_manager,  phase_code 
from fnd_concurrent_requests  
where phase_code='R';

# 根据 request id 找到 对应的<controlling_manager>
select request_id, controlling_manager,  phase_code 
from fnd_concurrent_requests  
where request_id = <request_id>;

# 根据 <controlling_manager> 找到对应的<ORACLE_PROCESS_ID>：
select OS_PROCESS_ID, ORACLE_PROCESS_ID 
from fnd_concurrent_processes 
where CONCURRENT_PROCESS_ID = <controlling_manager>;

# 根据 <ORACLE_PROCESS_ID> 就知道 SID
select a.sid ,b.spid from v$session a , v$process b 
where b.addr=a.paddr and b.pid = <ORACLE_PROCESS_ID>;

# 另外一种 SQL query 方法：
select session_id from fnd_concurrent_processes 
where CONCURRENT_PROCESS_ID = <controlling_manager>;

select sid from v$session where audsid=<session_id>;

===========================================
# 统计 每个 program 对应完成的 request 数量：

select a.concurrent_program_id , b.CONCURRENT_PROGRAM_NAME, count(1) 
from fnd_concurrent_requests a, fnd_concurrent_programs b
where a.concurrent_program_id = b.concurrent_program_id
group by a.concurrent_program_id,b.CONCURRENT_PROGRAM_NAME;

===============================================
# 列出 concurrent program的种类

col LOOKUP_CODE for a10
col meaning for a60

select lv.lookup_code, lv.meaning from fnd_lookup_values lv
where lv.lookup_type='CP_EXECUTION_METHOD_CODE' and language='US' order by 1;

# 列出 concurrent program的种类对应的数量
select lv.meaning , count(*) from fnd_lookup_values lv,
fnd_concurrent_programs cp where lv.lookup_type='CP_EXECUTION_METHOD_CODE' and
language='US' and lv.lookup_code=cp.execution_method_code
group by lv.meaning order by 2;

select cp.enabled_flag,lv.meaning , count(*) cp_count
from fnd_lookup_values lv,fnd_concurrent_programs cp 
where lv.lookup_type='CP_EXECUTION_METHOD_CODE' and
language='US' and lv.lookup_code=cp.execution_method_code
group by cp.enabled_flag,lv.meaning
order by cp.enabled_flag, cp_count;

==========================================================
# 列出正在运行的 concurrent manager processes: 

select CONCURRENT_QUEUE_NAME, control_code, running_processes, max_processes 
from fnd_concurrent_queues 
where running_processes != 0

========================
# status code 对应的解释 <297909.1>

select lookup_type,lookup_code, meaning from fnd_lookups 
where lookup_type like 'CP_%';

# fnd_concurrent_processes 的 status_code

select lookup_code, meaning from fnd_lookups 
where lookup_type='CP_PROCESS_STATUS_CODE'


# 如何手动停掉正在运行的 Concurrent Request <154688.1> 

update fnd_concurrent_requests set status_code='C',phase_code='c' 
where request_id=4374195;

# <152763.1> , in that case, set status_code='X'
# check the meaning of status_code of requests from the note above

update fnd_concurrent_requests set status_code='C' ,phase_code='C' 
where request_id = 2722233;

# The Oracle server process might become runaway. 
# find out the sid first to kill it manully if needed.

==================================
# 如何在命令行上提交 concurrent request

CONCSUB apps/apps SYSADMIN "System Administrator" SYSADMIN WAIT=N CONCURRENT FND cusupt3 PROGRAM_NAME="custom update 3"

"cusupt3": concurrent executable in $FND_TOP/bin


# 如何 trace concurrent program
===================================
metalink note: 453527.1

1. concurrent program => define => "Enable Trace" 

2. Profiles => System => Concurrent:Allow Debugging

3. submit request => Debug Options


# 各种 不同的 concurrent programs
Concurrent Program 可以用不同的方式构成， 既可以用 shell，PL/SQL, C, JAVA 等
语言，也可以用 Oracle Reports，SQL*loader 等工具。下面逐一介绍。
====================================== 
example 1 : shell concurrent program
=======================================

cd $FND_TOP/bin
vi WH1TEST.prog

cat ./WH1TEST.prog
===========================
#!/bin/ksh
. /applvis/apps/apps_st/appl/APPSVIS_mis.env

sqlplus apps/apps@VIS <<EOF
EOF
echo "END"
=========================

chmod +x WH1TEST.prog

### pass parameter as separate variable

ln -s $FND_TOP/bin/fndcpesr WH1TEST

然后，在R12中逐一定义如下内容：
concurrent executable 
concurrent program 
Responsibility : Request 
request group (system Administrator Reports)

## start concurrent program "WH1TEST" manually
CONCSUB apps/apps SYSADMIN "System Administrator" SYSADMIN WAIT=N CONCURRENT FND WH1TEST PROGRAM_NAME="WH1TEST"

select CONCURRENT_PROGRAM_NAME, PROGRAM_TYPE from 
fnd_concurrent_programs where concurrent_program_name likE '%WH1%';

====================================================================


example 2: c & pro*c concurrent program
========================================
基本上参考 metalink <113428.1>。因为内容比较长，不在这里列出。

example 3: report concurrent program
===================================
这里只是copy 现成的一个test Oracle Report 做示范。
cd $FND_TOP/reports/US

Note: the report file should be in US directory.

cp /applvis/apps/tech_st/10.1.2/reports/samples/demo/test.rdf ./WH1RPTCP.rdf

[applvis@mis US]$ pwd
/applvis/apps/apps_st/appl/fnd/12.0.0/reports/US
[applvis@mis US]$ ls -l WH1*
-rw-r--r--  1 applvis dba 98304 Aug  9 17:40 WH1RPTCP.rdf
[applvis@mis US]$

then register this rdf as in other cases of the concurrent testing program
use "WH1RPTCP" as the Execution file name. (note: without the .rdf suffix)

but in the "define" part, choose "pdf" as output format .
=================================================

example 4: PL/SQL concurrent program
===================================
参考 metalink <73492.1>。

[oravis@mis ~]$ cat plconc.sql
create or replace procedure WH1plcp(errbuf out varchar2, retcode out varchar2) as
begin
fnd_file.put_line(FND_FILE.LOG, 'WH1plcp begins');
fnd_file.put_line(FND_FILE.OUTPUT, 'WH1plcp output');
insert into t1 values('WH1PLCP');
commit;
fnd_file.put_line(FND_FILE.LOG, 'WH1plcp ends');
end;
/
[oravis@mis ~]$

### submit conc request in PL/SQL
### ref <221542.1> 
### note that CONC_REQUEST_ID returns -1. <878636.1> 
declare
v_id number;
v_id2 number;
begin
--(user_id, responsibility_id, app_resp_id) 
--(sysadmin, system administrator, application system admin)

fnd_global.apps_initialize(0,20420,1);

--(app short name, conc program short name )
v_id := APPS.FND_REQUEST.SUBMIT_REQUEST('FND','FNDSCURS');
v_id2 := FND_GLOBAL.CONC_REQUEST_ID;
commit;
dbms_output.put_line(v_id);
dbms_output.put_line(v_id2);
end;
/ 

### find out relevant info
select * from fnd_application_tl where application_id = 1 ;
select * from fnd_user where user_name ='SYSADMIN' ;
select * from fnd_responsibility_tl where responsibility_name = 'System Administrator';
select * from fnd_user_resp_groups where user_id = 0 ;
select * from fnd_conc_req_summary_v where program_short_name='FNDSCURS';
select * from fnd_conc_req_summary_v where request_id=  314020 ;
### check the stauts of an conc request

declare
l_req_id number;
l_phase varchar2(30);
l_status varchar2(30);
l_dev_status varchar2(30);
l_dev_phase varchar2(30);
l_msg varchar2(2000);
status boolean;
begin
l_req_id := 314021  ;
  status :=fnd_concurrent.get_request_status(REQUEST_ID=>l_req_id, 
  PHASE=> l_phase, STATUS=>l_status, DEV_PHASE => l_dev_phase, 
  DEV_STATUS => l_dev_status, MESSAGE => l_msg ) ; 
dbms_output.put_line(l_req_id ||':'||l_phase||':'||l_status||':'||l_dev_phase||':'||l_dev_status);
end;
