Running SLD on Java-only system

Can I use a Java-only system for my SLD server when I have ABAP-only servers in my environment. The ABAP-only servers would be sending their information to this Java-only SLD

To setup a gateway service on a Java-only machine do the following:
1.
Edit the profile START_SCS00_##### adding the following two lines
_GW = /usr/sap/<SID>/SYS/exe/run/gwrd $(FT_EXE)
Start_Program_05 = local $(_GW) pf=/sapmnt/profile/<SID>_JC00_#####
2.    Edit the file DEFAULT.PFL adding this line
a.    rdisp/sna_gw_service = sapgw00
1.    Edit the file /usr/sap/<SID>/exe/scs.lst adding two lines
i.    gwmon
ii.    gwrd
3.    Restart JAVA on the server
4.    You can check the status of the gateway using the command:
a.    gwmon   pf=/sapmnt/profile/<SID>_JC00_#####

Copy VMWare image of Java only system

Hello,
We are running an SAP Java only System (NW 7.0) with a MSSQL 2000 DB on Windows running VMWare. We are trying to create a clone of that server to create another JAVA only SAP system.
We have changed the Computer Name in MSSQL and that is up and running. We have also changed the instance profile paramters to point to the new Server name.
Couple questions:
1) Is this possible to do with a JAVA only system?
2) The JControl process keeps failing. I've changed the instance.properties file to point to the new server host and when I start the system it keeps pointing back at the old one. Is this file defined somewhere else?
Has anyone done this before or tried it? If you have, can you provide any tips or tricks on how to accomplish this.
Thanks,
Dale Dingmann

Table in PI JAVA only system & Report development in JAVA only system

Dear Experts ,
We are migrating from Dual to Single stack JAVA only PI system.
In Dual stack system all the message data are stored in ABAP table from which MONI pulls data .
But in JAVA only system how data is stored ..? and how to access those table ..?
we need a report to develop which will have these data .
Interface name
Date & time of run
Key Data (if possible would like to see key data from the run, for example po number, material number, part number, idoc number would all be considered key data)
Pass/Fail flag
Error Message (only required if the run failed)
How & where to write code to develop this report ...?
thanks

Change timezone in Java-only system

Does anyone know how to change the timezone on a Java-only system?
I have already added the setting "-Duser.timezone=America/Dallas" on the configtool, but when I look at the logs in NWA, it still looks like it is reporting on GMT timezone.
Thanks!

EWA for Java only systems

Hi,
I'm searching for a guide to set up EWAs for Java only instances. Currently I have my Java instances in SMSY as system components, but how do I set up the EWAs as only ABAP instances are selectable. I'm using the latest SP, so this functionality should be available finally. I can't find a document about that anywhere, just some very bad documented snippets in SPRO...
Regards,
Pascal

Hi Pascal,
EWA for Java systems is currently in a pilot phase. It will be released with the note 976054, which is currently still being processed internally.
Note 976054 contains a setup instruction for EWA for non-ABAP-components.
Technically, for pure Java systems the "Central SDCCN" of the Solution Manager is used as indeed pure Java systems do not have a SDCCN.
Double stack installations do not make use of the Central SDCCN, using their local SDCCN to obtain the non-ABAP data that is collected by the Diagnostics part of the Solution Manager.
The note will be released in the very near future.
Best regards,
Walter Heibey

Can Java only system use CTS+?

We have 3 Java only (EP7.0) systems.
We also have a SM7.0(A+J).
Can we configure CTS+ for the EP7.0 using SM7.0 as the domain controller?
Thanks a lot!

Hi Jennifer,
YES it's possilbe. The very basic rational for CTS+ is to support Java based transports.
Please refer to this SDN post for How...to setup CTS+ for your portal

How to create a support message in a JAVA only system?

PLease help, thanks!

Hi Jennifer,
Work Center are the new interface within SAP Solution Manager shipped as of Stack 15.
They are developped with WebDynpro, which allows an easy Web integration.
http(s)://<host>:<port>/sap/bc/webdynpro/sap/ags_work_incident_man
http(s)://<host>:<port>/sap/bc/webdynpro/sap/ags_workcenter
Work Center Incident Management would handle
- Create Message
- Follow-up on created message (reply, confirm, add texts, add attachments)
for the end user, who created the incident.
Due to the Web Access, granting authorizations is quite easy and the user can not perform unexpected tasks.
Usage requires ideally a name user in SolMan system for Logon and a Business Partner.
See also these threads to setup and adapt Work Centers:
[Setup Work Center|Re: SOLMAN SP 15 - NOT ASSIGNED TO WORKCENTER]
[Adopt Work Center|Re: Incident Management Work Center Customizing]
(By the way, current SolMan release is 7.0, as 4.0 was renamed)

NW04S Java - Distributed System. DB Instance migration to new hardware.

Hi, I have a distributed NW04S Java only system. CI and CSC on Host A and DB on host B.
1.We want to move the DB instance from Host B to Host C. We will move the database from B to C using Oracle methods. What are the steps that need to be done on the CI/SCS instances/Host A to make the application connect to the DB on host C instead of B.
2. The new DB host is actually a node of 2 node MSCS setup. How can we enable clustering for the DB instance alone and still make the CI?SCS connect to the clustered DB?
For unavoidable reasons we do not want to follow the sapinst/jload system copy method.
Any directions, higly appreciated.
Thanks-Gopalan

Hi, I ve managed to get this working.
3 simple steps
1. Change db host entries in the Default profile
2. Change tnsnames.ora to new DB host in usr..\profile\oracle\ in the App Host.
3. Change host name in secure store on app server using config tool.
Thanks

XI on java only

Hi,
Can we install XI on java only system?
Thanks and Regards.

Hi,
No, it is not possible.
You need both ABAP and JAVA stack.As different stakc of XI handle different functionality.
J2EE stakc containd the J2ee adapters while ABAP stack has the Integration Server with BPE, Integration ENgine. etc.
Take a look at the XI architetcure Overview ,

Push ERP to SLD in JAVA system only

hi
i have been trying to push my erp system into my java only sld but i can't make it work. The sld_uc and sld_nuc always fails, can you please help?
regards,

hello,
Which java version you have installed? Only Netweaver 7.3 comes with a gateway service, in old releases you need to register sld_uc and sld_nuc in another gateway service, you can maintain this in the sld parameters.
hope you can solve your problem.

How to enable ping service on java-stack only system

I have installed SAP NetWeaver 7.0 - Java Trial on local host.
How can you activate the ping service there?
It should work under "http://localhost:50000/sap/bc/ping"
(I know how to activate it with transaction SICF in an abap system, but I have java-stack only here, so I can't call transactions. I can only use the Visual Admin, right?, but there I could not detect a ping service so far)
More detailed:
I created system "SAP_WebDynpro_XSS". (this is necessary for connecting to ECC abap backend for ESS Packages) and set following parameter:
template:"SAP system using connection string"
     category: Web Application Server
          Web AS host name: chrisSAP:50000
          Web AS path: /webdynpro/dispatcher/
          Web AS protocol: http
But when I test the "SAP Web AS Connection" for this system, I got following error:
7. The Web AS ping service http://chrisSAP:50000/sap/bc/ping was not pinged successfully. If the ping service is not activated on the Web AS, you can try to call the ping service manually.
8. An HTTP/S connection to http://chrisSAP:50000/webdynpro/dispatcher/ was not
obtained successfully; this might be due to a closed port on the Firewall.
I guess step 8 did not pass because step 7 failed, and not because of a closed port or firewall (I made sure everything is open.)
The strange thing is that the connection test fails, but the connection seems to work fine!
I mean I can see the front ESS page in the portal when logging in with an ESS-user, and there are no errors in the log. If I change the SAP_WebDynpro_XSS parameters to some other made-up values, then the front ESS page does not come up and some errors appear with "SAP_WebDynpro_XSS" inside.
That proofs that the connection is working despite the failed connection test, right?. But what can I do that the connection test passes? It seems that somehow SAP has hardcoded the path "/sap/bc/ping" which usually exists on an abap system. But I have java-stack only, so how can I tell that the function that runs the test?
A system connection test fails, but the connection is working fine!
If someone could explain that to me...

Dear Srini Nookala,
thank you for your answer. Unfortunately I don't understand the relation of my question to your answer.
>> check with OSS note 1019335 SAP NetWeaver AS Java 6.40 SP21
I have Version 7.0 SP14. I read the OSS note, but there are around 100 changes listed. I read them all, but couldn't figure out one that has to do with ping and system test. So which sentence inside the note are you referring to?
>> The problem is due to JCo parameters configuration not properly, Ask Basis team, they will do it.
I am basis team. I configured the JCo properly as described in manual and tested them afterwards. They run successful. Also all the links that you gave refer to JCO connections about how to set them up and test them. But what have JCO connections to do with System-connection tests? As far as I know JCO-connections are not used for system connectivity tests. You can set them up independent. I understand that JCO-connections are used for getting data from backend servers. But the system "SAP_WebDynpro_XSS" is defined for determing the webdynpros on localhost (frontend, not backend).
So please can you explain me what JCO-connections which refer to remote hosts have to do with a ping service on local host that cannot be reached? And which part would be not configured "properly"? Timeouts? user?
To define my question more properly:
Is it possible to make the connection test work on a java-stack only host for a system that refers to itself (localhost)? Or is it a known bug?
Some sub-questions
Am I using the right system template (I am using "SAP system using dedicated application server")
I have no abap on local host (chrisSAP). Only java stack. Usually path ..sap/bc/ping refers to an abap system, right? So in my opinion I have 3 possibilities:
- install abap-stack on local host (portal) and activate ping service.
- somehow install a ping service that runs under the given URL in Visual Admin (how?)
- somehow tell the connection test to skip pinging and continue test. (How?)
Any additional advice would be highly appreciated.

AS JAVA technical system not updated/registered in SLD

Hi,
We have setup the SLD bridge connection from our SLD with 7.0 SAP J2EE
server which is our local SLD to SLD with 6.40 SAP J2EE server which is the master or central SLD. Actually we have this set up, that we have configured a local SLD for our Netweaver 2004s SR2 or Netweaver 7.0 system and connect it to the central SLD which is also a Netweaver system but of lower release, Netweaver 2004 SR1.
Since Netweaver contains both ABAP and Java, I can see that our WAS ABAP technical system (of the SLD 7.0) was
succesfully registered and updated on the central SLD 6.40 but I cannot
register or update the WAS JAVA technical system (of the SLD 7.0) in the central SLD 6.40, but it can be updated in our local SLD which is then connected to the central SLD as mentioned.
Since my update for the WAS ABAP was already working and its updated
in the central SLD 6.40, what can we do to achieve the same result for the WAS
JAVA? Because if it works with WAS ABAP, what is wrong then with WAS JAVA? What might be the cause or some other configurations to be made?
Also can we synchronize the CIM updated with all the SLD? We want to
see if we can just update the CIM content of SLD 6.40 and pushed this
with the other SLD on the system e.g. SLD of 7.0.

Hi,
I think you should certain configurations for your system to be listed under SAp Java systems.
1.Go to visual admin,c:\usr\sap\SID\JCxx\j2ee\admin
run go.bat.
Then go to services-----SLD Data supplier.
go to Http settins under that,enter the details of central SLD you want to connect,
hostname,http port,sld admin user and password.save it.
go to CIM client settings,enter the same details there and save.
Then check CIM client generation test.it should be sucessfull.
then trigger SLD data transfer at the top left corner.
it also should be sucessfull.
Then your system will be listed.
2.may be you have to create a role called Lcr administrator with all Lcr* actions assigned to it.
then this Lcr administrator role should be assigned to ur administrator user.
hope this works.........
reward points if helpful............
