Close RFC Connection

Hi,
I have some problems with the availibility of my WebDynpro-Application. It seems to be, that to much connections are opened at the same time. Is it necessary to close the connection in the code or should it closed by the system automatically?
To use a model I use the following code(example):
wdContext.nodeZ_Rfc_GetData_Input().bind(new Z_Rfc_GetData_Input());
wdContext.currentZ_Rfc_GetData_InputElement().modelObject().execute();
wdContext.nodeOutput().invalidate();
I don't know if there is a option to close the connection.

Hi,
Use below code:
wdContext.currentRFC_InputElement().modelObject().modelInstance().disconnectIfAlive();
Please check below forum ,
webdynpro JCO - RFC Connections are not closing in back end ECC (SM51)
Regards
Deepak

How to close RFC connection in one script coding

In one script, I am using the REF command to call another 2 scripts and these called scripts shd be run on same C36 ( test system). I shd close RFC connection between these 2 scripts.
That is , once the 1s script over the RFC shd be closed and the user has to give usename and pwd then 2nd script shd run.
I have tried with the following code. But it says RFC is not open
REF ( Y04S_FC_RM_CJ88_112 , Y04S_FC_RM_CJ88_1 , C36_999 ). (when execute this script RFC to C36 will be created and after execution that RFC shd be closed so I included following ABAP code)
ABAP.
data : dest type RFCDEST.
move 'S4_SAPC36999' to dest.
move dest to v_dest.
*--Close the connection before opening it incase it is opened
 call function 'RFC_CONNECTION_CLOSE'
 exporting
 destination = dest
 exceptions
 destination_not_open = 1
 others = 2.
 if sy-subrc <> 0.
 endif.
 move sy-subrc to v_subrc.
ENDABAP.
REF ( Y04S_FC_RM_CJ44_112 , Y04S_FC_RM_CJ44_1 , C36_999 ). (here agagin the RFC will be created and this script will be exectued.)

Open and close RFC connection with portals...

Hi Experts,
I created a RFC having a query which is taking a long time to execute. So i want to close RFC connection with portals which is via java connector(JCO) before that query and open the connction again after that query.
Please advice is it possible to achieve this. If yes, then how.
Regards,
Guddan

Hi Guddan,
I created a RFC having a query which is taking a long time to execute. So i want to close RFC connection with portals which is via java connector(JCO) before that query and open the connction again after that query.
I guess i will need to understand your requirement a little more in detail, as i understand you have an RFC which has a query within to fetch some data and is taking a long time to do so. In the meantime you don't want to keep the connection open?
My question would be, Is the role of this RFC to only execute the query and fetch the data or does it do something else?
If it does other things and these are independent of the query execution, then you can span a parallel call within the RFC to execute the query and in the meantime the RFC does the other things (or vice versa) hence reducing the overall time taken.
If the sole purpose of this RFC is to execute the query, then you will not be able(i mean to say there is no simple and direct way of doing this) to close the connection after the Query is started and re-establish the connection after its execution, for a simple reason that - how will you know if the query has completed it's execution, so that you can establish the connection back.
Alternate solutions, make this a two way asynchronous call, 1) You invoke the RFC asynchronously and close the connection, the RFC in turn will execute the query and transfer the data to JCO via another RFC call.
If this needs to be a synchronous call, then you will need to optimize the query to its best.

Chen

Need to close RFC connection

Hi all,
Currently we developed a application in NWDS, the same is operational from portal.
As per the requirment we have to run the RFC many times to extract the data from R/3. After running the RFC many times
we are getting the following Error "Error connecting using JCO.client: null"
But if we redeploy the application the problem is solved but after a while the same issue is persisting.
Please suggest how the problem can be solved ??
Thanks,
vijay.

Hi venkat,
Thanks for the example suggested by you.
The following is the RFC iam executing many times.
Z_Hr_Aprsl_Init_Input input= new Z_Hr_Aprsl_Init_Input();
input.setI_Usrid("UserId");
wdContext.nodeZ_Hr_Aprsl_Init_Input_new().bind(input);
wdContext.nodeZ_Hr_Aprsl_Init_Input().currentZ_Hr_Aprsl_Init_InputElement().modelObject().execute();
the code iam using to close the connection is
JCO.Client client = JCO.getClient(" "); // Please specify the parameter to be used to refer the above RFC
client.disconnect();
Please suggest the required the parameter to close the RFC connection
Thanks
vijay

How to close RFC connections

The RFC connections to the R/3 backend system are not closed when I close my iviews which are created in the Visual Composer. Each time the iview is reloaded, an additional RFC connection is opened...
Has someone a solution for this problem?
Kind regards
Frank

Hi Frank,
The connector pool keep the connection alive to be reused by the model iViews datasource, those connections will be closed at the timeout or when CLEANUP runs.
It's not a problem is the way how the connector framework works
You can adapt the timeout according SAP Notes 913483 & 314530

Unable to open RFC connection - Err message

I all
I am trying to install SAP ERP 2004 SR1 on Microsoft Windows Server 2003, SQL Server 2000. I have successfully installed the Central Instance but when I try to install the Database instance after the database loading the following error is given:

I have also tried to start the sap system. The message_server and igswd processed run ok, but the disp+work process is stopped.
I am also sending you the developer trace for this process.
Thank you a lot

How to specify a variable in the path prefix of an External HTTP (RFC) connection (in transaction SM59)

Hi There,
Please can someone tell me how to specify a variable in the path prefix of an External HTTP (RFC) connection in transaction SM59?
For example if my path prefix is /invoke/test/example?input=XYZ; how do I replace "XYZ" with a variable so that I can pass in any value after "=" ?
Thanks,
Brendon

Kill the RFC connection as soon as the call is completed in Web Dynpro JAVA

Hi Experts,
Please guide us how to kill the RFC Connection from web dynpro java as soon as the execution is completed.The FM connection (Adaptive RFC) isnt getting closed in IS-U side. Please guide us how to close them explicitly.
We are getting the following error
(102) RFC_ERROR_COMMUNICATION max number of cpic clients exceeded (300)

hi suvankar ,
wdContext.current<Modelname>_InputElement().modelObject().modelInstance().disconnectIfAlive();
use this option after executing your rfc, it will remove the connection to the r/3.
adn this
(102) RFC_ERROR_COMMUNICATION max number of cpic clients exceeded (300) -- is occuring because the pool size defined the jco destination is not sufficient, ask your basis team to increase the pool size.

Govardan

RFC Connection remains open after portal logoff

Hi,
We have configured Universal Worklist in our EP7 EHP1 SPS4 Portal.
When a user connects to the Portal and launches the UWL it creates an RFC connection to the backend ECC. However, when the user moves away from UWL iview or logs out or closes the browser the RFC connection in the backend still
remains and is released only after the timeout value reached as set in ECC.
Are there any settings on the portal or ECC to release the session immediately once user moves away from UWL or logs out of portal ?
Thanks,
Savy.

Hi my friend
It costs time and resources to establish an RFC connection, therefore it is not immediately deleted but maintained by the system to be reused. But in case there're special purpose to control RFCs, here're 2 parameters to do so:
The parameter gw/gw_disconnect is a timeout in seconds to close the TCP connection between two SAP gateways if there is no RFC connetion on it for the given timeout. But if there is an active RFC connection onit it will not be closed even if there is no traffic on that RFC connection. Thats why you need another parameter.
The parameter gw/keepalive is used to periodically check all active RFC (and other) gateway connections if there was no traffic on them for the given time.

RFC connection not disconnected on timeout/logoff.

Dear Sir,
We have two systems of ITS, one with ITS 620/patch 16 connected to ECC 5.0 and second, with ITS 620/patch 4 connected with 4.7.
The one with patch 16 is perfectly working while the one with patch 4 have following problem.
1. ~event=logoff doesn't close the RFC session to R/3.
2. After the timeout period i.e set in ~timeout and ~usertimeout parameters set in global services, the RFC connection doesn't get closed.
Can this be a patch level problem?? or do the following R/3 parameters with 0 value have impact??
a. em/stat_log_timeout
b. gw/deallocate_timeout
c. gw/reg_keepalive
d. gw/timeout
Please guide...

Hi All,
We are facing the same problem. but we are not using ITS, we are using
WAS 6.20 on CRM4.0
Problem is: Open RFC connections build in the system, are not closed after the user sessions are closed / terminated
Can anyone help us to solve this problem.
Thanks

Standard way of mutual exclusion control for rfc connection

Dear expert,
I want to know the standard way of mutual exclusion control
for rfc connection.
I am going to create JAVA screens for ERP ABAP objects.
As for SAP GUI screen, pessimistic locking is used when editing objects.
On the other hand, pessimistic locking is defficult for JAVA screens,
since most of lock objects on ERP are not available for RFC.
Besides, I'm afrraid if locks are correctly deleted
when something bad happens on screen.(i.e. Users close browsers.)
Do you have any recommendations?
Regards,
Fukuhara Yohei

Hello, we raised an OSS note.
They answered it was not possible to lock tasks.
Task completion is like a race, the first it completes it wins.

Marco.

Create new user session after RFC connects

Hi,
My client is non SAP. They connect to SAP through an intermediate software , using RFC connections. My client requires that when creating a BOM through BAPI, the "created by" column should have a user name they pass, and not the username with which the RFC connected .
Is it possible to have a FM in which I can create a new user session, passing username and password, call the bapi that will create the BOM with this username, and close the session?
Kindly help.
Thanks in advance

Most security audits will trigger a warning when they determinate that the RFC common user is allowed to use another logon id. Usually you can provide auditors a list of such id with explanation before the audit execution, sample of explanation to provide :
- The RFC enabled FM which create the batch job must pass the logon id to be used, and the calling application must not allow user to change this value.
- The RFC default logon, should be allowed to the minimal authorization required, and could be for example allowed to no transaction, only some RFC FM. (start with [Note 460089 - Minimum authorization profile for external RFC programs|https://service.sap.com/sap/support/notes/460089])

Anup,
the entry sapmsDEV is missing in your "services"-file on the computer that hosts your SLD-Server/J2EE WAS. Windows locates it at %WINDIR%/system32/drivers/etc, unix usually at /etc/.
make an entry like that:
sapmsDEV   3600/tcp (in case, your Systemnumber is 00, otherwise replace the "00" with your actual systemnumber)
