Concurrent calling of Host function

Hi all,
I had using HOST() function in my form's library to sent label printing command to printer, it work ok when only 1 client is print label, but when there is concurrent client calling printing label function, one of the label not success to printed and no error return. I had trace my program and both client is calling HOST() to send the label to printer, but I had no idea why one of the label not successful to printed out. Please Help!
Beside that, is that any log file can i refer to whether HOST() function return any internal error that didn't show on the screen?
Thanks in advance.
p/s: I'm using webForm and my OracleAS version is 9.0.4.3

Hi,
I'm calling 'c:\bin\rfprint.exe "\\172.21.9.123\GENERICT" c:\wm\setup\lbl\166_609026.lbl >> c:\wm\temp\label.log'. 1st parameter is a application to print label. 2nd parameter is printer name, 3rd parameter is label file and 4th parameter is log file.
Thanks.

How we can limit the number of concurrent calls to a WCF service without use the Singleton pattern or without do the change in BizTalk Configuration file?

How can we send only one message to a WCF service at a time? How we can limit the number of concurrent calls to a WCF service without use the Singleton pattern or without do the change in BizTalk Configuration file? Can we do it by Host throttling?

Hi Pawan,
You need to use WCF-Custom adapter and add the ServiceThrottlingBehavior service behavior to a WCF-Custom Locations.
ServiceThrottlingBehavior.MaxConcurrentCalls - Gets or sets a value that specifies the maximum number of messages actively processing across a ServiceHost. The MaxConcurrentCalls property specifies the maximum number of messages actively
processing across a ServiceHost object. Each channel can have one pending message that does not count against the value of MaxConcurrentCalls until WCF begins to process it.

Can I call MS Excel Function in Oracle

Hi everyone,
I prototyped my application in Microsoft Excel. In this prototype, I'm using the BETADIST() function, which returns the cumulative beta probability density function. And, yes, if you're like me, and not a statistician, it's pretty crazy. Just for fun, check out the wikipedia page on it, and you'll see what I mean. Anyway, so now, I'm trying to perform the same functionality as that function in my Oracle APEX 4.0/Oracle 10g-R2 app.
I've studied this function a bunch, and I couldn't find an equivalent function in Oracle to do what this function does. CUME_DIST... nope, DBMS_STATS_FUNC... nope. So, I assumed I would need to figure out what exactly the function does and basically rewirte it in Oracle using PL/SQL. I've already got questions out on Statistics and Excel forums trying to figure that out.
But, before I go any further and reinvent the wheel by coding out the logic embedded in this function (which is very hairy, of course), I wanted to check with you all and see if there's a way to invoke this MS Excel function through Oracle. Not sure if an external procedure can get to an Excel library, or how to do it if it can.
Any ideas?
Thanks!
Mark

I'm pretty sure this BETADIST exists in Java already.Not natively I think.
But one can download Cern's COLT Libraries for High Performance Scientific and Technical Computing in Java.
Loading the libraries via loadjava
loadjava -user michael/xxxx@oracle_server:1521:oracle_sid -verbose -force -order -resolve -thin colt.jar concurrent.jarand creating a function
create or replace function betadist (alpha number, beta number, c number)
     return number
as
     language java
     name 'cern.jet.stat.Gamma.incompleteBeta(double, double, double) return double';
/is rather straightforward.
Calling it
SQL> select betadist(4,5,0.4) from dual
BETADIST(4,5,0.4)
         ,4059136
1 row selected.the result coincides quite well with the example given in http://www.excelfunctions.net/Excel-Beta-Dist-Function.html.

Call SQL Server function through the gateway

Hello, Does anyone know if it is possible to call a SQL Server system function such as SERVERPROPERTY through the gateway?
I'd like to call a system function in the same way as a user defined function and not using DBMS_HS_PASSTHROUGH.

Maybe I need to be a little bit more precise. It really depends on the data types being returned. When you look at the SERVERPROPERTY function you mentioned earlier and try to select for example the Collation, then SQl Server will return a SQL_VARIANT data type and that will fail - even using passthrough as SQL_VARIANT is not a supported data type.
Let me use the passthrough example as it allows me to demonstrate it easily:
SQL> SQL> declare
2 val varchar2(100);
3 c integer;
4 nr integer;
5 begin
6 c:= dbms_hs_passthrough.open_cursor@DG4MSQL_EMGTW_1123_DB;
7 dbms_hs_passthrough.parse@DG4MSQL_EMGTW_1123_DB (c, 'SELECT SERVERPROPERTY(''Collation'') as Collation');
8 LOOP
9 nr:= DBMS_Hs_Passthrough.fetch_row@DG4MSQL_EMGTW_1123_DB(c);
10 exit when nr=0;
11 dbms_hs_passthrough.get_value@DG4MSQL_EMGTW_1123_DB(c,1,val);
12 dbms_output.put_line(val);
13 end loop;
14 dbms_hs_passthrough.close_cursor@DG4MSQL_EMGTW_1123_DB(c);
15 end;
16 /
declare

ORA-28511: lost RPC connection to heterogeneous remote agent using

ORA-06512: at line 6
Process ID: 16919
Session ID: 148 Serial number: 16721
When I now make sure the return value is a char data type by slightly modifying the select and including a convert it will work:
SQL> declare
2 val varchar2(100);
3 c integer;
4 nr integer;
5 begin
6 c:= dbms_hs_passthrough.open_cursor@DG4MSQL_EMGTW_1123_DB;
7 dbms_hs_passthrough.parse@DG4MSQL_EMGTW_1123_DB (c, 'SELECT convert(char,SERVERPROPERTY(''Collation'')) as Collation');
8 LOOP
9 nr:= DBMS_Hs_Passthrough.fetch_row@DG4MSQL_EMGTW_1123_DB(c);
10 exit when nr=0;
11 dbms_hs_passthrough.get_value@DG4MSQL_EMGTW_1123_DB(c,1,val);
12 dbms_output.put_line(val);
13 end loop;
14 dbms_hs_passthrough.close_cursor@DG4MSQL_EMGTW_1123_DB(c);
15 end;
16 /
SQL_Latin1_General_CP1_CI_AS
PL/SQL procedure successfully completed.
Just in case you have a procedure that returns the correct data type you have to make sure the gateway is configured correctly which means the parameter
HS_FDS_PROC_IS_FUNC needs to be set to TRUE and the function you want to call is listed in the HS_CALL_NAME parameter.
Here for a userdefined function I have to specify:
HS_FDS_PROC_IS_FUNC=TRUE
HS_CALL_NAME = "dbo.fx_SumTwoValues"
and then the udf based select:
SQL> SELECT "dbo"."fx_SumTwoValues"@DG4MSQL_EMGTW_1123_DB('7','8') AS SumOfTwoValues from "dummy"@DG4MSQL_EMGTW_1123_DB;

A Runtime error: Generation successful, but you must call up the function

I used Professor Jim Menching's AIS materials in fall 2009 before ECC 6.04 was installed and everything worked plug-n-play without too many problems. I tested assigned client after my client provider migrated SAP from ECC 6.0 to 6.04.
I tried to proceeded "receive the product from the vendor" on page 13u2019s step 11 after creating an purchase order, as following:
Logistics> Materials Management > Purchasing > Purchase Order > Follow-on Functions > Logistics Invoice Verification (MIRO)
I tried to save it. However, I got an error message: "Generation successful, but you must call up the function". After I did it one more time, it becomes a runtime error! I am not savvy for dealing with unknown technical problem. Can anyone provide me with a solution to fix problem?
Thanks in advance.

Picheng,
Thanks for the post. I forwarded your question to your hosting site for resolution since this is a technical issue ... and the technical team informed me the issue was already resolved. If you have further issues related to this specific issue please contact the UCC directly.

How to call a C function calling a Java Method from another C function ?

Hi everyone,
I'm just starting to learn JNI and my problem is that I don't know if it is possible to call a C function calling a Java Method (or doing anything else with JNI) from another C function.
In fact, after receiving datas in a socket made by a C function, I would like to create a class instance (and I don't know how to do it too ; ) ) and init this instance with the strings I received in the socket.
Is all that possible ?
Thank you very much for your help !

Hard to understand the question, but by most interpretations the answer is going to be yes.
You do of course understand that JNI is the "API" that sits between Java and C and that every call between the two must go through that. You can't call it directly.

How to call a SQL function from an XSL expression

Hi
In R12, in Payroll Deposit adivce/Check writer, We need to sort the earnings tag <AC_Earnings> in to two different categories as regular and other earnings. In the DB and form level of element defintiion we have a DFF which differentiates between the two kinds of earnings. But the seeded XML that is gerneated by the check writer does not have this field.
The seeded template displays all the earnings in one column. How can we achieve this in the template without modifying the seeded XML.
The one approach i have is to write a function and based on the return value sort the data. For this I need to know :
1) How to call a SQL function from an XSL expression that is allowed in BI template.
If anyone ahs faced similar requirements please share your approach.
Thanks

OR
Call it thru Xsl? (I donno how to do dis)
Thanks in Advance..

Problem while calling an RFC Function Module in Background

Hello,
I have created a RFC function module for reading data from an external DB system. The FM calls an external RFC program (coded in C++ using RFC SDK), which delivers the required data. This external program is maintainged as an TCP RFC Connection in SM59.
Further I have created a report, that calls the RFC function module to get the data from the external RFC programm.
My problem is, when I call the report in foreground, everything works OK, the RFC connection works and data can be read from the external program.
However, when I schedule the report to run in background as a job, the report is stating in the protocoll that there was a problem calling the defined RFC connection (although the connection is working properly at that time).
More funny is, this particular problem with running in background occurs only in the productive system, in test and development system the report works correctly also while running as a job in background.
Can you suggest the solution to this problem? Could it be something with authorisations or server settings?
I will be on holiday for the next 6 weeks, so take your time to answer .
Regards,
Dusan.
Edited by: Julius Bussche on Jan 22, 2009 7:19 PM
Please read the forum rules about u r g e n t ...

This is an external RFC server program, not a remote enabled ABAP RFC function module as the others seem to be assuming, right?
Is it possible that your DEV and QAS systems only have one application server, but the PROD has many and dedicated one(s) for processing low priority background jobs?
It might be that the target server of your TCP connection is not this BTC instance, and your RFC server is returning the data "locally" - so, into nirvana...
Just guessing, but might be worth checking.
Cheers,
Julius

How can I have a backing file call a JavaScript function?

I have a Weblogic portal with a JSP portlet. The portlet has a backing file. How can I get the backing file to call a JavaScript function in my portlet?
thanks

Hi
your questions are not correct because you are mixing up server side operations with client side operations.
First server side code executes then the page is sent to the browser , then any javascript executes on the browser. So asking for javascript to be called from backing file (server side) doesn't make sense or asking for javascript to read a parameter doesnt exactly work either.
However in your server code suppose you have a variable action in the request that you want javascript to know then in your JSP you would add something like
<script type="text/javascript">
var action = '${requestScope.action}';
alert(action);//or whatever you want to do
<c:if test="${requestScope.someOthervariable == ''xyz'}"><%-- this check is done on the server --%>
callSomeJavascript(); <%--this javascript is only executed when the server side value of someOtherVariable is xyz --%>
</c:if>
</script>
i.e. you can output the javascript that has the variables you need or the function calls you want.
Like I said understand whats server side and whats client side.

How can I call a plsql function from an attribute?

I have an attribute defined in an element. I want execute a PLSQL function from the attribute, and display the returne value with an HTML template.
I've defined the attribute's type like PLSQL, and I've put the called of the function in the value of the attribute, but it doesn't work. The only value I obtain is an URL (I think that is the URL of the function or someting like this).
How can I call to my function from the attribute and display the returnes value in the page?
Thanks.

Thanks, but it doesn't work. I have an attribute called ID_BOL and I want to associate a sequence to that attribute. I've created a function, with the sequence. This function return de value of the sequence. I want taht the attribute takes the value of the sequenece dinamically.
I've tried it, creating the type attribute like PLSQL, and calling the function from the attribute, but it doesn't work.
How can I return the sequence value to my attribute?
Thanks.

Visual fortran calling a c function in visual studio

Hi,
I am running Windows 8.1 with Visual Studio Prof. 2012. I have installed Visual Fortran also. Now I wanted to make a solution with two projects one for Visual Fortran and one for C, and be able to call a C function from within the Fortran.
Can someone, please, show how to do this step by step? Guide with pictures would be awesome.
Thanks in advance.

Hi Engineer101,
One way to integrate your code into TestStand would be to save it as a .dll file. Cick this link for information on how to do this in visual c++ 2008. Once you have the dll, you can call it in teststand using a c/c++ dll action step. I hope this helps, and let me know if you have any further questions!

How to call the 'DETAIL' function in ALV for a program?

Dear Friends,
I have a prf_tree (TYPE REF TO cl_gui_alv_tree), and I added below codes to add an new button for displaying the detail record, it works fine:
CALL METHOD prf_toolbar->add_button
    EXPORTING
      fcode     = prf_tree->mc_fc_detail
      icon      = icon_detail
      butn_type = cntb_btype_button
      text      = ''
      quickinfo = 'Show Details'.
Everytime I click this new button, a window will popup and display the record details.
My question is: how to call this standard function ('DETAIL' function) in a program? for example:
CASE ldf_ok_code.
    WHEN gcf_okcode_save.
      PERFORM okcode_save.
    WHEN 'SHOW_DETAIL'.
      CHECK gdf_nodkey_9003 IS NOT INITIAL.
      PERFORM SHOW_DETAIL.(How to write this code to display the detail data of the selected record?)
Thanks a lot!

Hi,
Go for Interactive Reporting
like When u click on the output then it will show the Detail report u want .
for that purpose Pls
Use Hide command .
And call another report

Calling Synchronous RFC Function Module in Background

Hi all,
Currently we are working on some requirement where in we have to retrieve data from one system(CRM) and update the same into another system(ECC). We have developed a RFC Function in CRM system and it is being called from ECC system as in synchronous mode via a batch program.
Now since all sychronous call to a RFC function will be dialog there is a constraint on the runtime which is being set by maximum run time for each dialog work process. So my question is there an option to call an RFC function synchronously in background (background task) so there is no runtime performance.
The standard TRFC, QRFC calls in background runs asynchronously and so I am trying to check with the SDN world as whether has anyone tried SRFC(Synchronous) call in background?
Thanks in advance,
Jagath

So my question is there an option to call an RFC function synchronously in background (background task) so there is no runtime performance.
One solution would be to increase the value of the "time out" parameter defined the CRM system. This i feel is not a fool-proof solution as the run-times cannot be predicted. Check this thread: Re: RFC timeout profile parameter
For me a better solution would be to implement tRFC call instead of a synchronous call. Any reasons why you don't want to implement a tRFC ?

Calling a RFC Function Module

Hello Guys,
I have a question regarding calling a RFC function module.
In BW - BI 7.0 I call a RFC function module:
(The ABAP program in BW-BI 7.0 is below)
CALL FUNCTION ''ZTESTFUNCTIONMODULE' " Function module in ECC
     DESTINATION 'DECCLNT110' " ECC system
    TABLES
      it_gl_item   = it_gl
      it_errlog_gl = it_errlog_gl.
The 'ZTESTFUNCTIONMODULE'   is RFC enabled in the ECC system.
The purpose is we retarct the data from BW to ECC.
When I run the function module it always asks for the user id and password.
The SAP logon screen appears and it asks for the user id and password.
The destination is maintained in the SM59 transaction and also the user is maintained there. I think it should login automatically into remote system and return the tables. is it correct. How to skip the logon screen.
Do I have to pass the user id and password in the function module. I think it should take the user id from the SM59 destination. Is it correct.
Please advise. As always thanks for your help guys.

Hi Senthil,
I think you answered your query in your question itself
The user ID and password need to be maintained in RFC destination in SM59.
Go to SM59 and then click on test connection..if it does not ask for ID and passwoed that means correct ID and password is maintained in SM59 otherwise maintain it.

Atish
