User Id creation for Jco connections

Hi,
Need to create a user for verifying the Jco connections. Please help me with the steps of creation and how can it restricted only for verifying the connections.
Thanks

Hi Daneil,
Best way is to do it yourself.
1 - Create a user having full access (SAP_ALL and SAP_NEW and RFC Full access as well).
2 - Set up the JCO connection with this user ID.
3 - Put a trace (ST01) on this user ID and then test the connection.
4 - Analyze the trace file and create a role having all the access pulled in the trace.
5 - remove all the access from the above user and assign the role created in 4.
6 - Put a trace once again on this user Id, just to ensure that if there is a miss in any authorization(failure) then you will be able to capture that as well. Update the role accordingly.
Hope this helps.

Change password for JCO connections

Hi,
In our landscape we have around 80-100 applications running and there are 300-400 JCO connections on an average. We have 4 servers like this. Earlier we used to have developers user id and password for JCO connections. Now we have decided to have a universal userid and password for all the JCo connections. My question is there any way by which we can change the passwords for all the JCO connections without going to each one of them individually as it is a hectic task.
Thanks & Regards,
Vijith

Hi Vijith Kumar,
Look at the following blog:
/people/anilkumar.vippagunta2/blog/2007/02/06/dynamic-jco-creation
I guess that if you can create JCO by code you can also edit it...

Where can i find .properties file for jco connection?

For jco connection to SAP, we need .properties file. Is this file already contained in Exchange Profile or somewhere??
If yes, where can i find .properties file for jco connection or what is the path to this file?
OR, do we have to create manually??
Any help is appreciated.
Thanks.

Automating user creation for Unity Connection when sync'd with LDAP

Hi
Is it possible to automatically create users that sync with unity connection?
I have a unity connection 7.0 server that is sync'd with LDAP and i use a ldap filter so that only users with a specific attribute are sync'd. I can see the users when i try to do an import but is there anyway that they can automatically be created

No
Check this check box so that Cisco Unity Connection gets basic information on Connection users from the LDAP directories that you specify on the LDAP Directory page. Data is synchronized only for the Connection users that you created by importing users from the LDAP directory. Connection does not automatically create new Connection users when new users are added to the LDAP directory.

Authentication method for JCo connection in XSS installation

Hi All,
I have a query which perplexes me. I am implementing XSS (ESS/MSS) on SAP Portal EP6 SR1 with an ECC5 backend for prototype purposes.
When I follow SAP's help steps to setup JCo connections, it states that for the metadata connection you should use a security authentication method of 'User/Password', but for the application data connection you should use a security authentication method of 'Ticket'.
Does anyone know why the difference in methods here? Is it possible to use 'User/Password' for both? Any thoughts would be appreciated.

Hi john,
User -ID /Pwd method can be used to access the backend for both types of Data as per your scenario.
User -ID /Pwd method and logon tickets both can be used to access data in backend.
The difference lies in the scenario with which you are accessing the back-end.
If all your portal users are same as backend users then you can select Logon ticket methods.
If they are going to be different then you need User-ID /Pwd method .
Check the following link to get a clear picture:

Hope it helps.

Creation of JCO connection

Hi all,
i'm having a problem when creating JCO connections for WebDynpro.
When I create an "Application data" connection with "Single Server Connection" the connection is created sucessfully and I have successfull test and ping.
If I create an "Application data" conncetion with "Load Balancing" then the connection returns an error
"com.sap.tc.webdynpro.services.sal.sl.api.WDSystemLandscapeException: Error while obtaining JCO connection"
The Metadata connections it's only possible to create with "load-balanced connection" and then all of them gaves this last error.
Then, when I try to run an portal application for MSS/ESS it gave
"Failed to resolve connection parameter for 'SAP_R3_SelfServiceGenerics_MetaData'"
Someone knows why is that ? Can I pass over it !?!?
I'm stuck because I don't know what more can I do !!! I think that I've read all documentation about that !!
Best Regards,
Thanks very much

Error creation of JCO connection: System Already Exist

Hi Experts,
We have created the SLD connection to the ECC6.0 from the Portal 7.0.
Created one JCO connection using that SLD successfully for the Clinet 100.
Now we required to create one more JCO Connection for client200 also. But it is giving the Error that
System Already Exist.
How can we resolve this. When we create the JCO connection for one client, con't we create one more JCO connection for the same system for the differt client or not?
If so How do it?
Regards

I think you can add one more client in the existing connection. well, I am not sure about that even.

Port for JCO connection

Hi,
I am accessing an R3 table using JCO connection. Can someone please let me know the port no. of the server which will be neccessary for doing this?
Thanks

Hi Jacob,
try {
con = cgservice.getConnection("ISOILESconnect", cp);
ix = con.createInteractionEx();
ixspec = ix.getInteractionSpec();
ixspec.setPropertyValue("Name", "Z_MESSAGES");
rf = ix.getRecordFactory();
// CCI api only has one datatype: Record
RecordFactory recordFactory = ix.getRecordFactory();
MappedRecord importParams=recordFactory.createMappedRecord("CONTAINER_OF_IMPORT_PARAMS");
MappedRecord exportParams = (MappedRecord) ix.execute(ixspec, importParams);
output = (IRecordSet) exportParams.get("LI_MESSAGES");
This is the piece of code im using, I have already created a system on both the servers and tested them successfuly. But for some reason it works on one but does not give an output when i run it on the other server.
I get an error which tells me that no output is returned.
Thanks.

MII 12.1 time out for JCo Connection

I'm running this MII transaction that, is using a JCO connection to run a Function Module in SAP.
The problem we have is, that function module takes more than 60 seconds to run an return the values, that is correct because we are gathering a big amount of data, so if we run the function Module inside SAP it works ok, BUT, if we run the transaction from MII we receive a time out after exactly 60
seconds.
We have already modified several time out parameters inside MII
but those changes are not making any difference.
Do you know where that JCo time out parameter is inside MII 12.1?

Hi Salvador,
Try to increase the session timeout to 300 in SAP Menu --> System Properties. Initial it will be 60 sec only.
And increase MII workbench Read Timeout as well. Help --> Setting --> Read Timeout
If it doesn't solved your problem, go through below post

JCO connection error:Couldn't create JCOClientConnection for logical System

Hi All,
We are facing a production outage issue.
We have a Federated Portal Network setup where one of our producer goes down automatically (seems on heavy load).
On this Producer server we have 3 Web Dynpro applications deployed and default trace is full with JCO connection error   saying Could   not create JCOClientConnection for logical System: CSVMR_WD_MODELDATA_DEST.
We had issue with max allowed JCO connections so we changed the below mentioned parameters for JCO connection settings in portal:
u2022     Minimum value of JCo Pool Size in total = 80
u2022     Minimum value for CPIC_MAX_CONV per SAP Web AS = 320
u2022     Maximum Number JCo Connections = 160
Please let us know if we are missing on some settings, any help in this regard is appreciated.
Regards,
Priyanka

Hi,
As you have already increased the maximum number of connections/pool size but still you are facing this problem. I would suggest you to check the web dynpro application which might not be able to release/disconnect the JCO connection.
Please check this [Thread|How to close a model object connection for Adaptive RFC?; for more details.

Multilingual JCO connection setup

We want to make our Portal multilingual with the following setup. We have Portal 7.31 installed with following technologies,
- Java web dynpro applications using JCO destinations using user mapping (one hard coded userid/password), language specified in JCO destination is English.
- DynPage HTMLB applications using System landscape connection to SAP using user mapping (one hard coded userid/password). "Master locale" specified in the Landscape object is English
I wanted to change the language attribute in the JCO connection and landscape object so that the RFCs know the language required to send the data back. For JCO connections I can make another french language JCO destination and use that when user switches to french, probably I can do the same thing in case of system landscape object. Is this the right approach?
Would leaving the JCO destination language empty use the Portal user's language preference? Even though I am using a hardcoded userid/password?
Any help and direction appreciated.

hi,
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 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.

jo
