Problems creating JCO connector
We are having some problems when attempting to follow the steps indicated in the Post-Installation Slide Deck of RAR version 5.3. In step 4 (Create JCO Connectors) we are not able to create a new JCO connector associated with the given models in the WebDynpro Content Administrator. The "create" button displayed next to each model is disabled and the status indicated is "Status Unknown" (gray color).
When we test the SLD connection it is pointing to the default URL, while a different URL was specified during installation given an SLD already existed previous to SAP GRC installation.
Any ideas of where we need to be looking in order to fix this?
Hi Pablo,
This happens because your SLD bridge is not configured correctly ,
Please follow the steps as under :
Login to Visual Administrator.
Expand Navigation menu under J2EE Server Name ,
Expand Services List
Click On SLD Data Suppllier
Click On http settings tab
Enter Host name and port number , user name /password for your system connection.
Click Save.
Click on CIM Client Generation settings tabs
Enter host name port , user account details you entered in http settings tab .
Click Save.
Click Supplier ( data transfer)icon on top of pane to transfer data information you have entered in sld supplier.
A pop up window appears " trigger SLD data transfer" )
Click = yes.
A pop-up with appear indicating transfer successful.
If this window does not appear , then SLD needs to be configured properly,
launch http://<hostname>:<portnumber>/sld
Click on Administration > Initial setup
Fill in values for :
Object server name :Name of computer <SPACE> 1
E.g AG500900A 1
Gate way host : Name of computer as above.
gateway port : portnumber as used in URL .
Import software catalog check box = OK
Import SLD objects
(close to 95791 objects need to get imported , wait for sometime till they are imported )
After importing is done , refresh once.
This should resolve, however if you still face it then setup technical system at
http://<hostname>:<portnumber>/sld
HOME > Techinical systems .
Click new technical system
Select webas ABAP
the details need to be fetched from SAP R/3 system for which JCO is to be created.
thnks

Hi,
I want to create JCo rfcs in systems.
But confused between these functionalities :
1> JCo rfc prvider : This is present in Visual Admin and is used to register J2EE engine as rfc destination.
2> Maintain JCo connection : This is present in content admin in WebDynpro tool. Here we can provide details.
Whats the difference between two and which is to be used when?
ThanksHi,
JCo RFC Provider Service:
The RFC is an SAP interface protocol, which simplifies the programming of communication processes between systems. The RFCs enable you to call and execute predefined functions in a remote system, or in the same system. The RFCs manage the communication process, parameter transfer, and error handling.
In the J2EE Engine the RFC functions are implemented by the JCo RFC Provider service, which is used for processing ABAP to Java requests. A feature is provided for receiving calls from the SAP systems u2013 this is done by registering the J2EE Engine as a RFC destination.
The JCo RFC Provider Service processes calls from the SAP systems. It dispatches the calls to a stateless session bean, which is registered in the J2EE Engine naming system. By naming convention the JNDI name used is identical to the name of the SAP function module.
Technically, the service is based on the JCo (SAP Java Connector).
Please refer the sap help link:
http://help.sap.com/saphelp_nw04/helpdata/en/6a/82343ecc7f892ee10000000a114084/content.htm

Problems creating JCO Connections
Hi experts,
I have a question regarding the JCO Connection creation in Content Administrator.
My first doubt is if it's necessary to create each JCO Connection for each backend system that I'll run RFC functions?
If is it true, during Creation I must specify user and password. I have to specify the Backend User and Pass, right?
Finally, could you explain me why there are several JCO connections created?
When I create the JCO connection I will be able to invoque Backend RFC functions from, for example, a webdynpro?
Kind Regards,
Martin.Hi Martin,
1. Yes, provided you want to use the RFC functionality.
2. Yes, you would be giving the username and password for the metadata.
Please refer to [Creating JCo Destinations|http://help.sap.com/saphelp_nw70/helpdata/EN/3a/3b1b40fcdd8f5ce10000000a155106/frameset.htm]
3.Generally, when you install business packages like ESS MSS etc, there are a bunch of JCO which are installed as well, but all you would have to do is edit its properties and point them to the correct location.
4. Yes, you can.

<u>Can some one help me with this matter?</u>
Best regards Nir Shohat.Hi Nir,
We also had same problem but no we won't. Check ur config on SLD again and the try to the test connection from the http://localhost:4444/webdynpro ( WAS 6.4 )server.
If this connection is OK then deploy some small application n see.
Is ur's JCo connection working for J2ee application?

I'm having problems configuring the SLD and creating the JCo.
I'm using a RFC model from a R3 server that is not on the same network of my WEB AS. I want to configure the SLD using the IP address, but it only accepts the hostname.
There's a way I can configure the SLD with the IP address??.
Thank you.Hi Joaquin,
did you solve your problem by yourself and/or was Gregor's answer helpful for you? In the latter case, don't forget to reward some points for Gregor's answer.

Problem creating logical connector
Hello,
I would like to create an Event-driven Process Chain Modeler.
I started by creating Events and Functions (See the attachement metamodel)
Then, I started to create also additional connectors.But, I found a problem because I couldn't add the additional connector (AND) in the diagram.
The design file seems completed to me but I can't see how to I add the connector AND for example to the diagram.
please could you help me with this
ThanksThanks for you reply.
Yes, I understand that adding a DISCONNECT FROM SESSION will cause the recovery to work in the background
However , I waited 24 hours and no change
this is my test database , completely idle, so there is no massive recovery going on
When I issued :
select timestamp, message from v$dataguard_status
I got :
23-MAR-09
Media Recovery Waiting for thread 1 sequence 76
and also :
SQL> SELECT PROCESS, STATUS, THREAD#, SEQUENCE#, BLOCK#, BLOCKS
2 FROM V$MANAGED_STANDBY;
PROCESS STATUS THREAD# SEQUENCE# BLOCK# BLOCKS
ARCH CONNECTED 0 0 0 0
ARCH CONNECTED 0 0 0 0
MRP0 WAIT_FOR_LOG 1 76 0 0
I did notice that this archive log #76 was not transferred and when I query in the primary DB :
SQL> select recovery_mode from V$ARCHIVE_DEST_STATUS ;
RECOVERY_MODE
IDLE
UNKNOWN
IDLE
IDLE
IDLE
IDLE

Looks like something went wrong during my logical standby configuration, but I cannot figure out what exactly
The physical satandby was working fine.
thanks in advance for any help

SLD problem while creating JCO
Hi all,
I am creating JCO from WebDynpro Content Administration for a RFC model but when I go to JCO connections it don't allow me to create. The link is disabled and when I "check SLD" it gives error "Connection to System Landscape Directory (SLD) could not opended successfully"
can any one help me in this?
Thanks
NinadHi,
You can check and modify the SLD configuration settings of the J2EE Engine using the Visual Administrator. Log on as an administrator user and double click on Server -> Services -> SLD Data Supplier.
Switch to tab CIM Client Generation Settings. If the HTTP connection parameters host, port, user and password are not set, then the SLD is not configured to be used by Web Dynpro applications. Configure the parameters with the values of the central SLD system and save the configuration. Select CIMClient Test to test if the configuration data is correct and the connection to SLD could be established.

Error while creating new connector in GRC CUP 5.3
Hi,
I am trying to create a new SAP Connector in CUP 5.3, when i fill in all the fields in the new connection and select "Test Connection" it says Connection successful and when i save it and look at the Available connectors, i am unable to see my new connector there.
Does anyone know why is this happening.
a quick response is appriciated.
Thanks.
Edited by: Chaitanya Pallapotu on Jul 14, 2009 9:17 PMHi Chetan,
I have the same issue when configuring connectors in CUP. I solved it in this way:
1- Go to RAR(Risk, Analysis and Remediation) --> Configuration --> Connector --> Search
2- Select one of the connectors and write down the values in the list box of the field JCO Destination.
3 - Now, go to CUP, and create the connector using the names writed down in step 2.
CUP will warn you with an error, ignore it, and then save the connector.
Note: when creating the connector in CUP, fill the fields, then save/create(here you will have the error msg), then Test Connection, and then save again.
That works for me!!!
PD: Always log in to GRC with the same language configured in CUP.
Hope this works for you!!! -
Message Servers not appearing when creating JCO Destination
Hello Experts,
I had created a System Object in the Portal system landscape based on System Template (Template) and choosed SAP system with load balancing (to connect to R/3 server).
Given parameters to Connector, ITS, WAS and User management, when i test the connection test on these settings, All are successful except the connector settings. but when run the transaction code(System Administration -> support-> portal runtime-> SAP Transaction) by selecting this message server, it is executing.
And i want this message server to be selected when creating JCO destination.
This System Object is not showing in the message servers dropdown box selection when creating the JCO destinations.
What may be the issue.
Could anyone help me in solving this.
Thanks in advance
Regards
SunilHi,
Have you checked the Technical systems in the SLD ? When you click on check sld , you appear an SLD url ,,,
Typing the same URL in browser and loging inwith SLD USER .... have you seen all the technical system which you want to appear while creating the JCO's ..

<b>SAP Java Connector - Excample 1: Simple RFC call
Scenario
We will call the RFC function module ZNAS_HIE1_GET_MEMBER_FARM.that returns members that have owned a farm. Input to the function is a farm number, and output is a table of members that have owned the farm and Owner number (Sequence number of owners).
Class testJCO is excuted and calls class GetMemberFarm method GetMemberFarmFromSap. Input parameters to GetMemberFarm are Farm and Owner number.
GetMemberFarmFromSap executes RFC ZNAS_HIE1_GET_MEMBER_FARM, that returns a table of members that have owned the farm from the input parameters.
GetMemberFarmFromSap loops through the table and finds the member where ZZCHCODE (Owner numer), is equal owner number from the input-parameters. and returns the member.

Buttons disabled while creating JCO- SLD configured in solman
Hi All,
I have configured SLD in solman.And I have made relevant entries in Visual Administrator also.
When I try to create jco in my portal,all buttons are disabled.
I had faced this problem when I had configured SLD in portal itself and that got resolved after I searched through the forum.
But here I have no clue where i am going wrong.

The problem is that name of CJO is already exist in the SDL, that is correct beacuse this application is going to be used the same SLd in order to connect to the same SAP Systema QAS, Prod respectivelly.
How can i solve this problem, my intention is to have only 1 application Wd java with two deferents JCO destiny independent to avoid any change in the code afeact the deploy which is in productivo.
How can i managed this situation.
Thanks a lot for helping me.Hello,
There is no such option to use two JCo for a single WD Application as per your requirement. You can try with below two things
1. Create another model with another JCo name. Which took more effort to change the source code wherever you used the Model.
2. In your Production system delete/deactivate the old JCo (if possible) then deploy your application. Then it will create the JCo same as before. And if other applications are also using the same JCo there should not be any problem once they are newly created.
Thanks

The Following Procedure Follow To Create JCO Destinations.
First You Configure SLD Correctly.If You Have ECC And BW.You Maintaing Two WEBAS ABAP Systems.
You Create WEB AS ABAP System In SLD And Maintain Connection Properties Of ECC.And
Similarly For BW Also.
If You Want To Create JCO Destinations.You Go To Login Portal
Content Administration->Webdynpro->Create JCO Destinatiion
A.General Data -> Specify Model Name,Client And JCO Pool Configuration
B.Specify J2EEE Cluster
C.Destination type
Data Type-> Application DataModel,Dictionary MetaDataMetadata
Destination Type->Load Balancing Or Single Server
D.Specify Either Application Server Or Message Server
E.SecurityUsername,password,confirm password,language
F.SummaryWhole Information
