Name server not updated in development configuration after change of SLD

Former Member

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,

As i have commented on same questions,

If you have changed SLD inforamtion in NWDI. And created the track based on New SLD.

Now when you import in NWDS, you need to update select Window > Preferences >Java Development Infrastructure > Development Configuration Pool >> URL of the System Landscape Directory (SLD) server: http://HOST:PORT

Then Press the Ping server button to test the connection with the SLD. Press the OK button to close the Ping Server window.

If you still getting same error, Please update IP and host name in host file entry at (RUn > Drivers > etc > host file) and then try again.

Hope it helps now.

Thanks

Hi Jacob,

did you do a content transfer to the new sld server, or how did you to the switch to the new sld? As far as i know the SLD used by the nwd is stored in the SLD CIM Data, too.

On my NWDI I setup a NWDI Landscape with a SLD Server conected to the technical system.

For troubleshooting, first of all I would check where the CIM CLient points to on your NWDI server. If the CIM clients still points to the old sld this might be a problem.

I will check if i find the entry in my SLD content.

Maybe you can tell us how you transfered the content to the new SLD

Thank you

Hi Jan

Thanks for your answer.

The SLD content has been moved to the new SLD. I didn't do this my self, so I don't know how it was done.

As far as I can see the new SLD is an exact copy of the old, so if the SLD itself is setup in the SLD, then it makes sence, if it is still pointing to the old one.

The question is where to look in the SLD.

Does anybody know?

Hi Jacob,

Please check the SLD Data Supplier(Verify URLs, Username and password) in SLD administration (http://host:port/sld)

Also update SAP Data Supplier parameters in Visual Administration with your new SLD.

Hope it helps,

Hi Jacob,

I would proceed as follows:<br><br>

- login to your new SLD<br>

- go to the technical systems in the landscape area of the SLD<br>

- in the filter drop down select AS JAVA<br>

- 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<br>

- 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.<br>

- remember the name of the system here. it is like sid on dbhostname.<br>

- got to sld administration (link on top) choose content maintenace in administration<br>

- in the subset filter select "All with instances" as class set SAP AS JAVA Cluster<br>

- you should find your system there. click on it.<br>

- in the new screen find a link in the middle top <nr> associated instances -> click it<br>

- in the next screen you will see the relationship of the technical system to the rest of the sld data.<br>

- there should be a topic called "hosted application server"<br>

- the should be an entry like: system landscape directory: sld on sid on server -> click it<br>

- 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. <br><br>

You can although proceed as follows. This as well requieres you nwdi to report and use this sld in j2ee see below if not.<br>

- on sld startscreen choose landscapes in the landscapes part of sld<br>

- select landscape type nwdi systems<br>

- if there is no landscape you can create one<br>

- in the landscape ypu can assinge systems. The sld should be availabel to choose.<br>

- 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.<br>

<br>

you can although check:<br>

- open name reservation from develpoment part of start screen<br>

- here you should find a button about enabling or disabling the sld for nwdi usege. this should be of course enabled...<br>

<br>

<b>"change J2ee to new sld" <br>Ok and here what to do or to check if you are not sure if your NWDI uses/reports to the new sld.</b><br>

- 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.<br>

- ok in VA. select on of your server nodes->services->SLD data supplier.<br>

- an overview page will show up.<br>

- select the http settings tab in the lower middle.<br>

- 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.<br>

- 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.<br>

- if all is setup. do a cim client test.<br>

<br><br>

Allright. This is all I know on how the NWDI is integrated in SLD. Hope you can resolve your problem wiht this steps.

<br>

Have a good time<br>

Jan
