Role Name Server defined in SLD but no CimomURL maintained

Hello gurus!
We have a problem with our NWDI setup.
What I want to do is to update an existing track DFODEV02 with the software package EP-RUNTIME.
I synchronize with the SLD. However when I try to save, I get the following error:
"SLD (URL http://<NWDI_server>:<port>)
server exception: Invalid Name Server null - Check SLD configuration -> Role
Name Server defined in SLD but no CimomURL maintained."
I am not familiar with the customizing for this but I have looked into a couple of customizing steps related to Data Supplier:
1) Under administration on SLD I see the following:
Update Namespaces is marked as sld/active; but
Update Other SLDs is an empty list.
2) From the configuration on NWA:
Target URL: <RuntimeSLD_server>/sld/ds
Both 'Automatic send' and 'success' are both "true".
Hope that you can guide us on the right “track”
In advance, thank you very much!
Best regards,
Elias

Hi Elias,
1) Under administration on SLD I see the following:
Update Namespaces is marked as sld/active; but
Update Other SLDs is an empty list.
This is something else, your error message is not about this one.
What you need to make sure is that you have a name server defined.
You can check it in various ways:
A). go to CMS -- Track Data -- select the track in question -- tab Build Variants -- Display/Download the Development Configuration --> This will be an XML file. If you see a tag "sld-nameserver" then you are ok, however I assume this tag is missing or points to a wrong SLD in your case.
B)
Go to the initial page of the SLD.
2. Choose Landscapes.
3. Choose New Landscape…
4. In the page that appears, select the landscape type NWDI System.
5. Specify NWDI as the name of the landscape. Choose Create.
The new landscape is displayed.
6. Select the new landscape.
You see the details about the landscape.
7. Choose Systems and then choose Add System to Landscape.
8. Choose the hosted system type System Landscape Directory. Choose OK.
You see the installed SLD.
9. Select the SLD.
The details view appears.
10. Select the roles Landscape Server and Name Server and save your changes.
The name server is now known to the NWDI and can be used there. Only now can you create valid development configurations.
Could you please confirm this way whether you have a name server specified and that points to the correct SLD ?
I hope this guides you to the right "track"

Ervin

Invalid Security role-name error in Web Project

Hi All,
I have imported a J2EE application project built in JBOSS into NWDS 7.1.
While building the project i get the following error
CHKJ3020E:Invalid Security role-name error: PEHNTAHO_ADMIN
This error directs me to the following code in web.xml
<security-constraint>
 <display-name>Default JSP Security Constraints</display-name>
 <web-resource-collection>
 <web-resource-name>Portlet Directory</web-resource-name>

 </auth-constraint>
 <user-data-constraint>
 <transport-guarantee>NONE</transport-guarantee>
 </user-data-constraint>
 </security-constraint>
I have tried out the following things to resolve this issue :
1) Remove the role manually(as suggested by various people in other J2EE forums), but then some other error came in to picture
2)Then I added the following code in web.xml
<security-role>
 <role-name>PEHNTAHO_ADMIN</role-name>
 </security-role>
Then the above mentioned build error gets resolved, but then I get the following error while deploying the application.

Can anybody tell me the use of role "PEHNTAHO_ADMIN"?
Thanks and Regards,

Hi Malathy,
Once the users are created in Authentication Provider, and once the roles are created in Weblogic Server, You just have to map users to roles in Jazn-data.xml.
Could you please let us know you created a roles named users in WLS ?

Using Name Server

Hi,
I'm trying to use a set of prefixes for software and development components. I made the following alterations:
- reserved a namespace at the SAP marketplace
- marked in the SLD that the System Landscape Directory has role 'Name server'
- made a list of prefixes in the SDL that should be used while creating SC's and DC's
What I expected is that while creating a DC a drop-down box should appeared from which I could select the required prefix. Unfortunately nothings happens and when I try to create a DC a error-message appears that the prefix of the name of the DC is not correct.
What did I forget?

Hi,
Have you defined the Namespace Prefix that you would be using ?
This can be done at SLD Home > Name Reservation (under Development) > Define Namespace Prefix (under Namespace Prefix)
Name Category: Development Component Name
Namespace Prefix: example.org/appl (in this example appl will appear in combo box)
Hope this solves the problem.

Aayush

Hi david,
Have you been able to resolve this problem?

Logical file name or logical path name incorrectly defined

Dear All,
We are doing archival in our IDES for test purpose before we do it to our Production.
Steps Performed
Copied AM_ASSET archive object to ZAM_ASSET
Logical Path
Logical path ZAM_ASSET
Name Asset
Syntax group UNIX Unix compatible
Physical path /archive/test/<FILENAME>
Logical File Name
 Logical file ZAMASSET
 Name Asset
 Physical file FI_<MONTH>_<DAY>.txt
 Data format ASC
 Applicat.area AM
 Logical path ZAM_ASSET
But when we run the WRITE though SARA , in the job log we get the following
Logical file name or logical path name incorrectly defined
When generating a file name for an archive file that is to be created, the system determined that the logical file name FIAA_ARCHIVE_DATA_FILE or the logical path name ARCHIVE_GLOBAL_PATH was defined incorrectly.
But we have maintained a Logical name ZAMASSET , so we are unable to change the location of archived file and as well as the format.
So is there any setting we need to maintain apart from the logical file name and logical file path.
Suggestions are highly appreciated.
Thanks in anticipation

hi,
follow this steps :
- transaction SARA
- enter authorization objects, eg SD_VBAK
- hit button CUSTOMIZING
- Archiving Object-Specific Customizing: execute Technical Setting
- field Logical File Name enter or select ARCHIVE_DATA_FILE
- leave CONTENT REPOSITORY as blank if you are not using 3rd party for storing (eg. IBM Tivoli)
- back to customizing
- from Basis Customizing, execute : Cross-Client File Names/Paths
- on Logical FIle Path Definition, highlight (select) ARCHIVE_GLOBAL_PATH on the right pane
- double click on the Assignment of Physical Paths to Logical Path on the left pane
- double click on OS used, eg. UNIX, define Physical Path where archive file (on WRITE process) will be stored
- save changes made
- double click Logical File Definition, Cross Client on the left pane
- double click ARCHIVE_DATA_FILE on the right pane
- make sure that logical path is already set to ARCHIVE_GLOBAL_PATH
- save changes made
this setting also can be done using transaction FILE
we have experienced on this case using SAP standard archiving (SARA, SARI) and everything is fine with this setting above.
hope it help you.

Trex: Unable to find name server

We are in process of upgrading our portals from EP6sp2 to EP6SP9 and we have trex 6.0 server. Recently we have upgraded our dev portal to EP6SP9 and trying to configure trex fails. I have specified name server in J2EE engine but still I cant create indexes. I restarted the system but still no good.
 when I see trex monitor I get message "The name
server is not running or no name server is configured in TREX Service Properties. Start J2EE Admin to change the
properties."
 When I try to create the index "Index could not be
created; creating index failed: TREX Name Server
(including back-up servers) is down or not accessable.
(Errorcode 7217)"
How do I make my trex work. What am i missing
thanks,
Praveen

Hi,
The server is working and aswell my production server which is EP6SP2 is configured to the same trex server and I can search documents in Production server.
 Just wondering whether do I have to install Trex 6.1 for EP2SP9. I have given the name server as tcpip//<hostname>:8355. ? Any other Suggestion?
Thanks,

How to create Business System in SLD with Role "Integration Server"

Hi,
We were trying to create a Business system of role "Integration Server" in SLD. However, we are getting an error saying "There is already an Integration Server defined foer the selected Technical System. Select as Application System."
We could not find any relevant BS with the role "Integration Server" for that Technical System.
Please advice.
Warm Regards,
Bhaswar

hmm
I have same situation on a fresh installation.
Also error "There is already an integration server defined for the selected technical system; select the Application System role".
But, there is no Business system at all visible and also the Business system tab of the technical system is completely empty.
What to do?

Name server not updated in development configuration after change of SLD

Hi Guys
Hope you can help me with this one.
We have moved our SLD from one server to another.
After this we changed the name server in NWDI and in NWDS.
In NWDS i removed the development configuration and reimported it, but when I do this, a popup box shows the details of the development configuration and the name server is still the old SLD server. This means that when I start the NWDS I get an error saying that the name server host is unreachable.
Where do I change this?
I found out that the name server is setup in the .confdef file under .dtc\0 in the field called name-server-url. If I change this manually in the file, it works. But if I remove the development configuration and reimport it again, I am taken back to the old name server again.
It seems as if something has to be changed in NWDI, but I can't figure out what.
Can anybody help?
Cheers,
Jacob Vennervald

Hi Jacob,
I would proceed as follows: 
- login to your new SLD 
- go to the technical systems in the landscape area of the SLD 
- in the filter drop down select AS JAVA 
- check if your NWDI has reported to this SLD in the last 12 or 24 hours, you can check this on the "last update" column 
- if your system has reported to this sld the last few hours this is good if not go to the step "change J2ee to new sld" i will descirbe later. 
- remember the name of the system here. it is like sid on dbhostname. 
- got to sld administration (link on top) choose content maintenace in administration 
- in the subset filter select "All with instances" as class set SAP AS JAVA Cluster 
- you should find your system there. click on it. 
- in the new screen find a link in the middle top <nr> associated instances -> click it 
- in the next screen you will see the relationship of the technical system to the rest of the sld data. 
- there should be a topic called "hosted application server" 
- the should be an entry like: system landscape directory: sld on sid on server -> click it 
- here you will see the data for this hosted system. You can find the cim/url definig the SLD you will find the roles. Landscape and name server should assigend and so on here you can chage the SLD url. 
You can although proceed as follows. This as well requieres you nwdi to report and use this sld in j2ee see below if not. 
- on sld startscreen choose landscapes in the landscapes part of sld 
- select landscape type nwdi systems 
- if there is no landscape you can create one 
- in the landscape ypu can assinge systems. The sld should be availabel to choose. 
- once in the landscape you can view the system and you can change the CIM Server url and the roles there aswell its just another view on the content. 
 
you can although check: 
- open name reservation from develpoment part of start screen 
- here you should find a button about enabling or disabling the sld for nwdi usege. this should be of course enabled... 
 
"change J2ee to new sld" Ok and here what to do or to check if you are not sure if your NWDI uses/reports to the new sld. 
- Go to the nwdi server an open Visual admin i asume you are running a 7.0 Di if not let me knoe i can although tell you for CE. 
- ok in VA. select on of your server nodes->services->SLD data supplier. 
- an overview page will show up. 
- select the http settings tab in the lower middle. 
- https settings will tell the j2ee where to report to. Verify the data and change if needed. use the lightinigbolt button on top to transfer data to the sld. have a little patiance if your data is not shown immediately in your sld,. it may take 1-2 minutes until it is shown in the gui. 
- switch to cim client generation tab. those paraemters will tell your j2ee from what sld to read data from. It is important to understand that you may report to one sld but to read from antioher. depending on your sld landscape. The CIm CLient should use the same Sld as your NWDI uses in CMS setting. 
- if all is setup. do a cim client test. 
 
Allright. This is all I know on how the NWDI is integrated in SLD. Hope you can resolve your problem wiht this steps.
 
Have a good time 
Jan

After setup name server from SLD name prefix is still unavailable from nwds

Hi there
Although the nameserver is setup from the SLd, our developper team has told me that it does not work.
One of them has showed me from nwds, and I do not know how to fix it.
The name list is still unavailable from nwds while New Development Component creation:
Does anyone have any idea ?
Thanks,

Hi,
yes, there you should see the nameserver.
Proceed this way: Go to CMS webui -- Landscape Configurator -- Track Data -- select the track in question from the left hand side table -- RE-SAVE the track (Change and Save).
This action will update the server side development configuration.
Once the track is resaved, doublecheck the changes in the devconfig XML you can access on the Track Data -- tab Build Variants -- Display Development Configuration. An XML file will be opened where you should have an entry for nameserver. It'll look like
name-server-url="http://<your host:your port>/sld/cimom"
If it is correct, then open your NWDS and remove and re-import the development configuration.
Or try to trigger "Update" on it as you can see in the blog I sent you, but if that does not work then remove and reimport.
Check again the settings you have showed me recently on the screenshot, this time the "Name Server" on the Component Properties should not be empty any more.
I hope this helps. Let me know the results.
Thank you and Regards,
Ervin

NWDI for the 04s preview fails with 'SLD name-server configuration error'

After the installation, everything seems to work fine except that when I go to CMS, the links on the top seems to be hardcoded to point to http://pwdf3102:50100/dtr, even in the Domain Data. When I tried to change it to my local server, it keeps complaining about "Unexpected error; inform your system administrator: <Localization failed: ResourceBundle='com.sap.cms.util.exception.CMSExceptionMessages', ID='SLD name-server configuration error', Arguments: []> : Can't find resource for bundle java.util.PropertyResourceBundle, key SLD name-server configuration error"
Any suggestions on how to work around this? Thanks.

Brian,
Try to import the model file first by going to SLD->Administration->Import CIM Model. If the problem sticks, then try to remove the systems. The preview version has lots of pre-exist system name in the technical system, which you can find giving errors since they're not reachable. So you can remove them from SLD (Home->Technical Systems) if they are preventing you from procceeding.
You need to go to http://server:port/dtr/system-tools/administration/NameServerConfiguration to update the name server as well.
Hope this helps...

Hi Kranp,
As the issue is more related to Windows Server high availability

Can only define one name server??

Can someone please tell me how to add more than one name server to my router (WRV54G) to push out to it's DHCP clients? Under Setup > Network Setup, there's only room for one "DNS IP Address". All of my other Linksys devices allow for more. Firmware Version: 2.39.2. Thanks!

With WRV54G, no such option is available. It is available with WRV200

Logical System for Role Integration Server

Dear all,
I need your help to clear my confuse.From ID I had assign business system as defined by Role Integration Server but when I check Adapter-Specific Identifiers, nothing show in Logical System. I already define Logical system in SLD. but I'm not sure incase of Role Integration Server will show logical system same with role Application System or not. becasue the other one as role Application System it's fine.
Thanks and Regards
Park

Hi Park,
I could not clearly understand your question .But i think you want to know the roles of the Integration server and Application system.I would like to share some thing on their difference .Hope this will clearify you.
A business system can be configured as an Integration server or Application system:
Integration Server
The Integration server executes only integration logic available Integration Builder. They can also be identified as Pipe Line Steps. It receives XML message, determines the receiver, executes the mappings, and routes the XML message to the corresponding receiver systems. Thus configured Integration Engine is identified to be Central Configured Integration engine.
Note: Only one client of SAP system can be configured as Integration Server.
Application system
The Application system will not execute the integration logic. It in turn calls the integration server to execute the integration logic if required. It acts as sender or receiver of XML messages. So, the Application system with a local Integration Engine requires the Integration server to execute the integration logic
Thanks,
Ram.
