Oracle Submit Request - 请求的调用方法: FND_REQUEST.SUBMIT_REQUEST

废话:

有一段时间没搞过开发了,做项目又要重新找回点开发的记忆。重新拾回一点点零碎。

跑多了产线,配置的一些参数也忘记得差不多了,长时间没动就是易遗忘,找点资料做个笔记就是时间保镖。

 

正题:

FND_REQUEST.SUBMIT_REQUEST 函数是用来提交一个请求的,它返回一个NUMBER值.具体调用如下
   :result := fnd_request.submit_request(application CHAR, --模快
                                         program CHAR,      --应用程式
                                         description CHAR,   --请求说明(可选)
                                         start_time CHAR,    --RUN 时间(可选)
                                         sub_request BOOLEAN, --立刻提交请求
                                         argument1 CHAR,   --参数1
                                         argument2 CHAR,   --参数2
                                         argument3 CHAR,   --参数3
                                         argument4 CHAR,   --参数4
                                         argument5 CHAR,   --参数5.......
                                         argument100 CHAR);
英文说明 :
Parameters are as follows:
> application - Short name of the application associated with the concurrent  request to be submitted.
> program - Short name of the concurrent program (not the executable) for which  the request should be submitted.
> description - Description of the request that is displayed in the Concurrent  Requests form. (Optional.)
> start_time - Time at which the request should start running, formatted as HH24:MI or HH24:MI:SS (Optional.)
> sub_request - Set to TRUE if the request is submitted from another request and  should be treated as a sub-request.
> argument1...100 - Arguments for the concurrent request; up to 100  arguments are permitted. If submitted from Oracle Forms, you must specify all  100 arguments.


补充说明:
在用fnd_request.submit_request的时候,第五个参数用false,不要被参数名称误导;
这个函数有105个参数,前面五个定义请求本身,后面100个是传递给请求的具体参数,都是Char类型,
我们需要转换,默认值是chr(0),代表这个参数不用传递给调用的请求;

注意:

1. 在Package里面调用只需要传递需要的参数个数,因为它有默认值指示结束;
2. 在form里面则不行,要写满105个,而且我们参数结束之后要用一个chr(0)来表示结束 。

 

如何查Application(模块), program(程序)

有两种方法:一种是从界面上去查,第二种通过SQL去查。

方法一:

首先你需得先知道要执行哪支程序(名称)。查到后你可以看到有:简称,应用产品。简称就是Request中的Program项的值。

Oracle Submit Request - 请求的调用方法: FND_REQUEST.SUBMIT_REQUEST

然后依据对应的“应用产品”名称,到“注册”中去查找,会发现有个简称,而这个“简称”就是Request对应的Application的值。

Oracle Submit Request - 请求的调用方法: FND_REQUEST.SUBMIT_REQUEST

方法二:

SELECT DISTINCT

fa.APPLICATION_SHORT_NAME,

fa.BASEPATH,

fat.APPLICATION_NAME,

fe.EXECUTABLE_NAME,

fe.EXECUTION_FILE_NAME,

fcp.CONCURRENT_PROGRAM_NAME,

fcp.OUTPUT_FILE_TYPE,

fcp.OUTPUT_PRINT_STYLE,

fcpT.USER_CONCURRENT_PROGRAM_NAME,

fcpT.LANGUAGE,

fcpT.DESCRIPTION

FROM fnd_application_tl fat,

fnd_application fa,

fnd_concurrent_programs_tl fcpt,

fnd_concurrent_programs fcp,

fnd_executables fe

WHERE 1 = 1

AND fat.APPLICATION_ID = fa.APPLICATION_ID

AND fat.LANGUAGE = fcpt.LANGUAGE

AND fa.APPLICATION_ID = fcp.APPLICATION_ID

AND fcpt.LANGUAGE = ‘ZHS‘

AND fcpt.CONCURRENT_PROGRAM_ID = fcp.CONCURRENT_PROGRAM_ID

AND fcp.executable_id = fe.executable_id

--AND fcp.enabled_flag = ‘Y‘

AND fe.EXECUTABLE_NAME = ‘RVCTP‘ -- 要查询的报表简称

 

在FORM里提交REQUEST(模板)

在Form里面,可以用APPS.FND_REQUEST.SUBMIT_REQUEST
提交一个Request到Oracle Request Manager。
如果提交成功,该函数返回Request ID,否则,返回0。
初始化
在提交一个Request之前,我们会调用Oracle Standard的Procedure对这个Request做一些基本的参数的初始化。
APPS.FND_GLOBAL.apps_initialize
user_id =>APPS.FND_GLOBAL.user_id,
resp_id =>APPS.FND_GLOBAL.resp_id,
resp_appl_id =>APPS.FND_GLOBAL.resp_appl_id
);
FND_REQUEST.SUBMIT_REQUEST
函数APPS.FND_REQUEST.SUBMIT_REQUEST有105个参数:
APPS.FND_REQUEST.SUBMIT_REQUEST
(
APPLICATION IN VARCHAR2 DEFAULT NULL,
PROGRAM IN VARCHAR2 DEFAULT NULL,
DESCRIPTION IN VARCHAR2 DEFAULT NULL,
START_TIME IN VARCHAR2 DEFAULT NULL,
SUB_REQUEST IN BOOLEAN DEFAULT FALSE,
chr(0),‘‘,‘‘,‘‘,‘‘,‘‘,‘‘,‘‘,‘‘,‘‘,‘‘,‘‘,‘‘,‘‘,‘‘,‘‘,‘‘,‘‘,‘‘,‘‘,
‘‘,‘‘,‘‘,‘‘,‘‘,‘‘,‘‘,‘‘,‘‘,‘‘, ‘‘,‘‘,‘‘,‘‘,‘‘,‘‘,‘‘,‘‘,‘‘,‘‘,
‘‘,‘‘,‘‘,‘‘,‘‘,‘‘,‘‘,‘‘,‘‘,‘‘, ‘‘,‘‘,‘‘,‘‘,‘‘,‘‘,‘‘,‘‘,‘‘,‘‘,
‘‘,‘‘,‘‘,‘‘,‘‘,‘‘,‘‘,‘‘,‘‘,‘‘, ‘‘,‘‘,‘‘,‘‘,‘‘,‘‘,‘‘,‘‘,‘‘,‘‘,
‘‘,‘‘,‘‘,‘‘,‘‘,‘‘,‘‘,‘‘,‘‘,‘‘, ‘‘,‘‘,‘‘,‘‘,‘‘,‘‘,‘‘,‘‘,‘‘,‘‘
)
RETURN NUMBER;

 

例子

PROCEDURE SUBMIT_REQUEST(p_group_id number) IS

v_request_id number;

v_org_id number;

BEGIN

FND_GLOBAL.APPS_INITIALIZE(FND_GLOBAL.USER_ID,

FND_GLOBAL.RESP_ID,

FND_GLOBAL.RESP_APPL_ID);

select OPERATING_UNIT

into v_org_id

from ORG_ORGANIZATION_DEFINITIONS

where 1=1

and organization_id = :parameter.org_id;

v_request_id := FND_request.SUBMIT_request( ‘PO‘, ‘RVCTP‘, ‘‘, ‘‘, false,

‘BATCH‘, p_group_id, v_org_id, CHR(0), ‘‘, ‘‘, ‘‘, ‘‘, ‘‘, ‘‘,

‘‘, ‘‘, ‘‘, ‘‘, ‘‘, ‘‘, ‘‘, ‘‘, ‘‘, ‘‘,

‘‘, ‘‘, ‘‘, ‘‘, ‘‘, ‘‘, ‘‘, ‘‘, ‘‘, ‘‘,

‘‘, ‘‘, ‘‘, ‘‘, ‘‘, ‘‘, ‘‘, ‘‘, ‘‘, ‘‘,

‘‘, ‘‘, ‘‘, ‘‘, ‘‘, ‘‘, ‘‘, ‘‘, ‘‘, ‘‘,

‘‘, ‘‘, ‘‘, ‘‘, ‘‘, ‘‘, ‘‘, ‘‘, ‘‘, ‘‘,

‘‘, ‘‘, ‘‘, ‘‘, ‘‘, ‘‘, ‘‘, ‘‘, ‘‘, ‘‘,

‘‘, ‘‘, ‘‘, ‘‘, ‘‘, ‘‘, ‘‘, ‘‘, ‘‘, ‘‘,

‘‘, ‘‘, ‘‘, ‘‘, ‘‘, ‘‘, ‘‘, ‘‘, ‘‘, ‘‘,

‘‘, ‘‘, ‘‘, ‘‘, ‘‘, ‘‘, ‘‘, ‘‘, ‘‘, ‘‘ );

Commit;

FND_MESSAGE.DEBUG(‘已提交后台程序‘||‘:‘||‘Request_Id=‘||v_request_id);

END;

Oracle ERP等待报表运行机制

主要是用到了Fnd_concurrent.wait_for_ruqest这个function.
Fnd_concurrent.wait_for_request返回Boolean值,主要参数如下:
function FND_CONCURRENT.WAIT_FOR_REQUEST
(request_id IN number default NULL, --请求ID
interval IN number default 60, --检查时间间隔
max_wait IN number default 0, --最大等待时间
phase OUT varchar2,
status OUT varchar2,
dev_phase OUT varchar2, --请求运行阶段
dev_status OUT varchar2, --各个阶段状态
message OUT varchar2 --运行完成后输出信息)
return boolean;
dev_phase有Pending,Running,Complete,Inactive等几种,每种对应不同的Dev-Status,比如Complete阶段后就有Normal,Error,Warning,Cancelled,Terminated等几种状态。

例如:

BEGIN
   l_request_status := fnd_concurrent.wait_for_request(l_request_id,
                                                       5,
                                                       0,
                                                       l_phase,
                                                       l_status,
                                                       l_dev_phase,
                                                       l_dev_status,
                                                       l_message);

   IF l_request_status THEN
      IF l_dev_status = ‘NORMAL‘ THEN
         NULL;
      ELSE
         fnd_message.debug (‘请求运行不成功:‘ || l_dev_status);
         RETURN;
      END IF;
   ELSE
      fnd_message.debug (‘请求未完成,无法查看报表内容!‘);
      RETURN;
   END IF;

   editor_pkg.report (l_request_id, ‘Y‘);
END;

总结:FND_REQUEST.SUBMIT_REQUEST是一种通过后台方式提交请教的方法,可以在pkg和 form中使用,在form中使用要将参数写全。 FND_CONCURRENT.WAIT_FOR_REQUEST是一个等待当前请求运行完毕的程序,可以利用这个等待当前的请求程序运行完毕再运行下面的程序。


有时候提交请求一直会返回0的情况:
检查是否有初始化环境:

-- 在PLSQL中设定初始的方法
SELECT user_id

         INTO l_num_user_id
           FROM applsys.fnd_user
          WHERE user_name =‘user_name‘;


SELECT responsibility_id
           INTO l_num_resp_id
           FROM apps.fnd_responsibility_vl
          WHERE responsibility_name =‘responsibility_name‘;


SELECT application_id
           INTO l_num_resp_appl_id
           FROM applsys.fnd_application
          WHERE application_short_name = ‘app_short_name‘;


fnd_global.apps_initialize (user_id           => l_num_user_id,
                                            resp_id           => l_num_resp_id,
                                            resp_appl_id      => l_num_resp_appl_id
                                           );

 

-- 在Form设定初始的方法
-- 可直接引用全局变量
FND_GLOBAL.APPS_INITIALIZE(FND_GLOBAL.USER_ID,

FND_GLOBAL.RESP_ID,

FND_GLOBAL.RESP_APPL_ID);
