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.
Regards,
Marco.

Sample JAVA code using Resource Adapter for RFC Connections

Hi Java Knowledgeable Ones.
I have successfully deployed the SAP Netweaver J2ee Engine "Resource Adapter for RFC Connections to ABAP Systems" to my Web Application Server. Now I need to develop a JAVA application that would utilize this deployed resource adapter. The resource adapter specifies the SAPClient, UserName, and password. I am thinking that the JAVA code to invoke this connection would therefore not need to provide this information as it should be available in the resource adapter.
Do you have sample code that you could send to me showing how to do this?
Thanks,
Kevin

Hi Kevin,
this is actually no good style! You should not open the connection with the adaptor knowing the password. Usually it should work via a connection that uses only basic rights and the user has already authenticated and is using his security ticket.
For security handling see:

On a 3750 enhanced services port, are hierarchical queueing and standard queuing features mutually exclusive?

When you configure hierarchical queueing on an enhanced services port, should one also configure the egress queue chararcteristics such as buffer space and thresholds, shaped/shared weights, egress priority queue, etc., that is all of those characteristics that one would configure if one were configuring a port for standard QOS. In other words, on an enhanced services port, are the hierarchical queueing features using the modular QOS CLI and the standard egress queueing features supposed to be used together or are they mutually exclusive?

Hi Christine,
Answer to your confusion is in the following document.
http://www.cisco.com/en/US/docs/switches/metro/catalyst3750m/software/release/12.1_14_ax/release/notes/OL464603.html#wp58682
On an ES port, you can use LLQ (enabled with the priority policy-map class configuration command) and the egress priority queue (enabled with the priority-queue out
interface configuration command). By using these two features, you can
give priority to a class of traffic and avoid losing traffic when the
switch is congested. In previous releases (before the egress priority
queue was supported), you could put a traffic class into the
strict-priority queue, but congestion at the egress queue-sets could
result in the dropping of that priority traffic. The priority-queue out
interface configuration command enables you to prioritize the same
traffic class at the egress queue-sets, ensuring that priority traffic
reaches the hierarchical queues and is processed with priority.
you can also fine tune the Queue-sets for your desired results.

Program ID Required for RFC Connection

Hi All,
I'm trying to create a RFC Connection betwen SAP BI and SSIS (SQL Server Integration Services). In SM59 screen i'm unable to get the appropriate Program ID required for the connection. Could someone please help me in knowing how to get it.

Yogesh,
While creating TCP\IP type RFC destination, when you select Radio button "Registered server program", there you have to provide Program Id there. So for your information:
Program Id is a string which can be anything even your name.
i know only R3 and XI integration and in that case you will make your RFC communication channel active first with a program Id(ant thing) and with logon credentials of other system + gateway host and service.
then use that program id in RFC destination and test it.
If get empty request then RFC destination is ok.

Clinet for RFC Connection in Java Installation

hi ,
I am in the process of installing Java Add on for EP.
I have BW installed in Client 100
But during instlaltion pls tell me teh client no i should give for RFC Connection

Hello Balaji,
In case of BW only one client can be used as BW client. Since your AS ABAP the BW client is 100 it has to be 100 in case of Java Add-in as well.

Draft for RFC connection

Hi Experts,
could you write me pls a draft coding for an RFC connection?
Thank you!

You mean something like this:
CALL FUNCTION 'Z_FUNCTION_NAME' DESTINATION 'PRD'.
That's all there is to it. You just add the Keyword DESTINATION and the name of a destination mainted in SM59 to the CALL FUNCTION statement. Now that I have typed this, however, I question if this inquiry really belongs in the Web Dynpro ABAP forum. This seems more like a general ABAP question.
Hint - for WDA specific functionality you can use the Service Call Wizard to generate the context and the logic to call a RFC. Was that perhaps what you were refering to.

Is there a way to do version control for OpenScript?

Hi,
I dont see Openscript IDE directly offers version control capability. Is there any other way that we can use to achieve version control (e.g. seeking the alternative through third-party software/plugins) so that we whole team can concurrently work on the same copy of script and do check-in/out like in SVN?
Thanks,
Helen

Standard way to maintain property files for internationalization??

Hi All,
For multiple language support, normally we maintain a different property file for different languages.For example, consider English language.In my case, i placed all the labels for english in one property file through out my application.All french labels in one property file and so on.
My question is, Is it better to maintain seperate property file for each page also??? Or else, one property file is good enough for one language??? which is better?(interms of complexity and performance)

Here is how I mapped the taglibs in my XML file and it works fine:
<taglib>
<taglib-uri>/WEB-INF/struts-bean.tld</taglib-uri>
<taglib-location>/WEB-INF/lib/struts-bean.tld</taglib-location>
</taglib>The .tld files are in the WEB-INF/lib dir. To use them i put this line in the JSP file:
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="struts_html" %>Hope this helped,
Calin

Authorization Required for RFC user in R/3-APO system.

Could you please help regarding one authorization issue. I want to know the authorization required for one RFC user. Now this RFC user used for RFC connection of SAP R/3 - SAP APO system. user type is given dialog type and SAP_ALL profile has been given to this user id. Now I have to remove SAP_ALL from this user id in R/3 and APO system and provide the required the authorization in R/3 and APO system.
Regard
Auroshikha

The RFC authorisation depends completely on what the user is doing (ALEREMOTE?). We can't tell you what RFC auths your connection requires.
There is a guide to doing this here: https://wiki.sdn.sap.com/wiki/display/Security/BestPractice-HowtoanalyzeandsecureRFC+connections

Configuring RFC connections for load balancing.

Hi ,
We have the following landscape for our systems.
The database is installed on z/os , db2 (mainframe). The central services( SCS and ASCS) are also on the mainframe. So the message server is on mainframe.
The CI is on AIX and The DI is on AIX.
We have Logon groups configured and load balancing Configured and is RFC enabled.
1) When we connect to SAP using the SAPGUI and the portal connection is made to either CI or DI depending upon the best response times. Now recently we are running the mercury load testing, all the users are connecting to DI. Why are the users connecting to DI even though we have load balancing?
2) I have a system with SID BP0, with one CI and one DI. The logon group is BP0 and the message server name is cyrix. Now I have other another system EP0. I have created a RFC connection from EP0 to BP0. In SM59 I have selected the load balancing option, and provide the message server name, SID and logon group name. The connection does not work. If I connect directly to the CI or DI the connection works. Please tell me how can I configure load balancing for RFC connections.
Thanks
Manmath.

Dear 917996,
There are two types of load balancing:
- Client-side load balancing (setting up the tnsnames.ora on client side). More information here (http://ggsig.blogspot.co.uk/2012/04/client-side-
load-balancing-in-oracle.html). Very good video produced my friend Igor Melnikov is here (http://www.dsvolk.ru/oracle/racdd4d/demos/video/loadbalance/client/clientloadbalance_viewlet_swf.html)
-Server-side load balancing (remote_listener and setting service parameter clb_goal). Very good Igor Melnikov's video is here (http://www.dsvolk.ru/oracle/racdd4d/demos/video/loadbalance/server/serverloadbalance_viewlet_swf.html).
I have read about client side and server side load balancing. By editing tnsnames.ora I have enabled client side load balancing which is suppose to select listeners at random. then why does it only go to second node?Could you please show your tnsnames.ora on client?
Please can anyone help me to configure server side load balancing with SCAN. I have read many many post but couldn't find a clear answer.Based on your output (remote_listener string cmbtrnrac-scan:1521) you have already configured the server side load balancing.
SQL> show parameter listener
NAME TYPE VALUE
listener_networks string
local_listener string (DESCRIPTION=(ADDRESS_LIST=(AD
DRESS=(PROTOCOL=TCP)(HOST=10.1
7.67.214)(PORT=1521))))
remote_listener string cmbtrnrac-scan:1521How many SCANs do you use? Do you use DNS?

Facing problem with RFC connections

In the Maintenace View for RFC connections, when I press the 'Apply' button I am getting the message"You have no authorization to display the destinationu201D for all the 4 destination IDs"
Can somebody suggest on how to overcome this problem?
Thanks,
Mohammed Tauseef Ahmed

Hi
The message over here means the user with which you are logged into the control system and the CPIC user that you may be using to create RFC destinations to the other systems in the landscape do not have the right authorizations.
It is recommended that all the users have the role TDMS_USER (atleast) or TDMS_MASTER assigned to it.
Once the role is assigned it will work fine.
