Error during communication with System Landscape Directory: HTTP response c

Dear all,
I have redirected a SLD to our Q system. Everything in the Repository is working fine. What did I do:
- Adjusted settings in SLDAPICUST
- Adjusted SAPSLDAPI
- Adjusted LCRSAPRFC
- Adjusted the following values in the Exchange Profile:
com.sap.aii.connect.cr.httpport
com.sap.aii.connect.cr.name
com.sap.aii.connect.landscape.httpport
com.sap.aii.connect.landscape.name
So, SLDCHECK works fine.
The Repository sees the right SLD.
However, in the Directory I cannot choose an Adapter Engine (leaves blank) in my comm. channel.
Then I went to the RWB and got the following message:
Error during communication with System Landscape Directory: HTTP response code: 403 Forbidden
Where can I change something to make this work? Is this a user verification problem?
Thanks in advance for your input.

go through the notes :-
#764176 Error in XI due to inconsistent SLD contents
#720717 Reduce the number of System Landscape Directories

403 Error during communication with System Landscape Directory from RWB

Hi,
I've got a new install of PI (XI 7.0) SPS 10 and am getting an error whenever I try to access the SLD from RWB or Integration Builder. The SLD is running on the same server as XI.
I've been through the various config guides (strangely there doesnt seem to be one specifically for PI/XI 7.0), to configure RFC destinations, checked users are not locked etc.
I'm thinking it's probably a VA / Authorisations issue, but could use some ideas!
Here's a few errors just for reference (and future people searching!)

Error during communication with System Landscape Directory: HTTP response code: 403 (Forbidden)
Unable to read XI domain from the SLD. Monitoring cannot therefore be configured. Error message: com.sap.aii.rwb.exceptions.BuildLandscapeException: Error during communication with System Landscape Directory: HTTP response code: 403 (Forbidden)
No System Landscape Directory exists. Unable to generate the landscape
Unable to read software component versions from System Landscape Directory "my.server:51400" (have tried 8014 also)

Thanks,

System Landscape Directory: HTTP response code: 403 (Forbidden)

Hi,
After upgrading PI 7.1 (with local SLD) Stack06 -> Stack09 we have the following error in the runtime workbench. It seems that the connection
between PI and SLD is not working:
1) error in RWB -
Error during communication with System Landscape Directory: HTTP response code: 403 (Forbidden)
2) another error:
8 Message(s) : SLD agent unable to specify domain - Error class com.sap.aii.rwb.exceptions.BuildLandscapeException: Error during communication with System Landscape Directory: HTTP response code: 403 (Forbidden) - Attempt to create JCo connection object failed for domain domain.00.hfasapxi1 - Integration Server unable to specify a JCo client - No component names available from Integration Server - SLD agent unable to specify domain - Error class com.sap.aii.rwb.exceptions.BuildLandscapeException: Error during communication with System Landscape Directory: HTTP response code: 403 (Forbidden) - Attempt to create JCo connection object failed for domain domain.00.hfasapxi1
3) in the sld:
INFO com.sap.sld.api.builder.app.DefineHostedSystem: Communication exception in SLD ping (HTTP 403 = FORBIDDEN): http://hfasapxi1:50000/sld/cimom, namespace sld/active.
sldcheck is working and the users are not locked or not valid. All seems to be ok but I still get these errors.
Any idea ?

Hi Venu,
thanks for the answer but it seems to be something else. After searching for that problem I also ran the configuration wizard->PI self registration. This activity registers all the component of the PI, unfortunately it only registered the "integration server" part without the Adapter engine, domain, RWB and etc.
Also, when I trigger the registration of the adapter engine I get the following error in the default trace:
The AdatperEngine has not been registered with the SLD due to: com.sap.aii.af.lib.sld.SLDException: Could not register AdapterFramework to SLD. Reason: Self-registration of instance af.xid.hfasapxi1 of class SAP_XIAdapterFramework failed
the reason is unknown ... any idea ?

System Landscape Directory is not accessible

I am trying to get my end to end monitoring working but every time I try to log in and display it asks for a user and password and no matter which user I try it tells me i have no authorisations...
So someone suggested that I goto /nwa to implement the template...
When I go there and put in the user and password it comes up with System Landscape Directory is not accessible.
Does anyone know why this is? or what can fix it?
NOTE: It is worth mentioning that the SLD can be accessed by the IR and ID... and I can go on to the SLD directly so I don't understand this issue...

Hi,
>>>>Also I am on a PI system so should it be PIISUSER?
yes
you can also check for errors from VA

Error in communicating with Excel Calculation Services

When attempting to use Excel Web Access web part, I get "We're sorry. We ran into a problem completing your request. Please try that again in a few minutes."
Checked event log and found

System Landscape directory not available error,

I am still a beginner, and I am having some slight trouble understanding, what tools would be needed, and how to install. I am using the forums.
We have the MII Discovery Server up and running.
NWDS Server installation is done.
We have the MII track ready to be used for Development(SLD URL is available) , Userid and password available
I am working on installing the NWDS 7.3 Developer Workspace.
Would I also need to do NWDS Server install on my laptop?
Would these steps be sufficient?
1. Download and install JDK 1.6
2. Copy the file nwds-extsoa-7.3-SP00-PAT0000-win32.zip from:
<your download location>\51039309\DATA_UNITS\JAVA_IDE\distros\com.sap.netweaver.developerstudio.distribution.complete.extsoa\8.30.0.101020102100
to a convenient folder.
3. Extract the content and you will have a folder with name eclipse.
4. Launch the Netweaver Developer Studio from folder eclipse, you may want to create a shortcut on the Desktop.
5. If you haven't maintained JAVA_HOME property or if it's pointing to some other java version, eclipse will complain about it. In the dialog window locate the JDK 1.6 installation. Path to JDK 1.6 should be something like
C:\Program Files\Java\jdk1.6.0_25\bin
6. Restart the NWDS after this and select a suitable workspace.
7. Set the run time engine in NWDS, by going through the menu path:
Window->Preferences->SAP AS JAVA
Question:
1. I am unable to Set the run time engine in NWDS, please could you give me details steps with what I would need to enter for Instance Hostname and Instance Number...etc
2. As part of Development installation do I have to Modifying the Logon Page? Do I have to go thru the Server installation in order to start developing on eclipse environment?
I do not have the war file. How do i Copy the war file tcsecumelogonui.war from
<Installation drive>:\usr\sap\<SID>\J00\j2ee\cluster\apps\sap.com\com.sap.security.core.logon\servlet_jsp\logon_ui_resources\tcsecumelogonui.war
3. System Landscape directory not available error,
In the Component Browser when I right click and select New u2013 Development Configuration u2013 Import From System Landscape Directory (SLD) u2013 Next (Enter UserID and Password)

Trouble accessing System Landscape directory

Dear Gurus,
I am currently setting up the System Landscape Directory (SLD) on the Solution Manager 4.0 system. I have managed to access the main SLD page using http://server:8000/sld, however when I click on the Adminstrator link, and then eg. 'log'. I will get this message:
500 Internal Server Error SAP J2EE Engine/7.00
Application error occurred during the request procession.
Details:
com.sap.engine.services.servlets_jsp.server.exceptions.WebIOException:

Exception id: [000C29B5E9430058000000320000226800045399F55C32B9]
There are several other links in the SLD Administration that does not work and will incur the same error message as above:
details.jsp
systemmessage.jsp
and many others. I have checked in visual admin and all application s are up. Please advise on my current situation.
With Many Thanks and Best Regards.

Hi,
You dont have to create this user in the system.This is the defualt user created during installation. You will find this in the
001 client. Also to change the password u can use visual admin
or http://ip:5xx00/nwa use j2ee_admin here and login then change the password for the sld user.

You do not have permission to view the System Landscape Directory.

Hello there,
When I accessed my SLD from portal, it took me to the page but kept saying:
- You do not have permission to view the System Landscape Directory. Minimum required: UME role with permission com.sap.lcr.LcrUser and J2EE role LcrUser. See the SLD Post-Installation Guide for details
- SLD not configured; configure the SLD in Administration first.
I searched on these forums for the above error. Got some results, but nothing really substantial that has helped/fixed my problem.
I also read a bit on SLD from the pdf file named: System Landscape
Directory of SAP NetWeaver 2004s
I also worked on the security roles and actions to individual
users or user groups like for ex: the above pdf file advised I map the security roles from Visual Administrator, to the created roles in the portal. I've done that too. Like create a user group: 'SAP_SLD_ADMINISTRATOR' and create a user role corresponding to it, which would be: 'LcrAdministrator'
Then, I went to visual administrator, and clicked on 'Assign User Groups to Roles'
Even after this, I tried to access the SLD from portal: It is still giving me the same error I mentioned above in bold italics.
Can somebody please help me how to fix this issue?
Thanks
Dino.

Graham:
Thank you very much for making the effort to reply to my query.
But, it still hasnt solved my problem yet.. for some reason even though I followed your instructions and did what you advised.
I have attached a screenshot of my Visual Administrator screen that you advised me to modify/change.
Here it is: http://img166.imageshack.us/img166/2259/screenshot002co1.jpg
After I made the changes, I restarted the J2EE server and went to my portal SLD page: [http://org-x:50000/sld]
Tried authenticating usernames: LcrAdministrator and Administrator.
Both attempts resulted in the same error show below:
- You do not have permission to view the System Landscape Directory. Minimum required: UME role with permission com.sap.lcr.LcrUser and J2EE role LcrUser. See the SLD Post-Installation Guide for details
- SLD not configured; configure the SLD in Administration first.
I am wondering, if you would have another workaround regarding this issue, can you please let me know?
Thanks
Dino.

Unable to read software component version from System Landscape Directory "

I've worked in past creating/importing SWCV, but this is new system PI7.0 and stuck.
A) Is my understanding on resolution correct?
Should I go and apply notes 940309 and create client copy of existing client 001
 OR
change role of client 001; SXMB_ADMIN -> 'Integration Engine Configuration' to 'Integration Server'
I have no problem in using client 001 as Integration server, all I want is import of SWCV to work. Thanks. Appreciate the help.
B) Here is what I have done and the error:
1) Followed weblog below and created product, software component, technical system, business sytem in SLD.
/people/srinivas.vanamala2/blog/2007/02/05/step-by-step-guide-xml-file-2-xml-file-scenario-part-i
2) When I import the SWC from integration repository getting error
(Unable to read software component version from System Landscape Directory "server:5<system number>00").
C) Pointers used from the forum to debug the issue, but still no luck
Below are the points checked from the forum and all steps are correct, but still have issues with the import
1) check the RFCs SAPSLDAPI, LCRSAPRFC, connection test pass as the program ID registered with Jco
2) T-code SLDCHECK no errors (followed http://help.sap.com/saphelp_nw04/helpdata/de/78/20244134a56532e10000000a1550b0/content.htm)
3) T-code SLDAPICUST got user PIAPPLUSER, pwd is correct (reset the pwd)
4) logged using PIAPPLUSER http://server:port/sld and it works
5) One of the weblog SLD Check Failed (LCR_LIST_BUSINESS_SYSTEMS function doesn't work) referred to apply notes 940309
Notes: 940309
You are installing 'SAP NetWeaver 2004s SR1 ABAP+Java' Usage Type 'NetWeaver Process Integration (PI)'.
You don't want to use the default client 001, but another client as Integration Server.

applied portion (PIPostInstallProcess) of OSS notes 940309 and it resolved.
Note:
I still retained client 001 and didn't do client copy as mentioned in the notes. The wizard based CTC tool helped. Here are the details if someone has similar issue and want to know further details:
A NetWeaver Process Integration (PI) Installation (ABAP+Java) has two parts: Installation and configuration. The former is done by the Installer, the latter by the 'Central Template Configuration' (CTC) Tool.

Hi,
we had some issues recently with this, and the trace also mentions proxy issues. Could you please try direct connection in that preferences (in other words do not use proxy settings in NWDS) ?
Is it possible that there is some kind of web-filter application installed that is blocking the request?
I'd suggest to google for this error:
407 (Proxy Authentication Required ( Forefront TMG requires authorization to fulfill the request. Access to the Web Proxy filter is denied. ))
Perhaps the problem is not even sap related.
Is Microsoft Forefront TMG (Threat Management Gateway after some googleing) perhaps configured in the way that it is not allowing this request ? Perhaps the IT guys of your company could look into this.
Microsoft Forefront Threat Management Gateway - Wikipedia, the free encyclopedia
12209 Forefront TMG requires authorization to fulfill the request. Access to the Web Proxy filter is denied.

SolMan 4.0 Install fails at Configure System Landscape Directory

Hi
We are installing Solution Manager 4.0 on AIX 5.2 and DB2 8.2.4. At step 56 (Configure System Landscape Directory phase) the install fails with the following error:
TYPE=A STATE=503 INFO_SHORT=Error connecting to

The provided user data might be incorrect or user might be locked. CONFIGURATION=
The user J2EE_ADMIN can logon to via the gui to client 001 without errors.
Any help would be appreciated.
Thanks
Sam

Hi Sam,
Seems this is a typical problem with SAP J2EE /AddIn Installations (I had this often!!). The user is created in the J2EE user store but because his password is initial, the J2EE engine would not let him in. As I remember the installation tries to log on with user SLDDSUSER (or so, something with SLD...), so log on on to the J2EE Engine with this user (e.g http://<hostname>:<port>/useradmin) and you will be prompted to that your password is initial (also do this with user J2EE_ADMIN, always good idea to see that J2EE Engine works correctly). In most cases the configuration of the SLD will continue.
If this doesn't work, cancel the installation and configure the SLD manually (is no problem, because at that point of the installation procedure, the system is fully installed, except the SLD configuration).
Hopes this helps.
Regards
Daniel

Error in communicating with DCR

Preliminary question:
     For LMS 3.2 on Windows, which is better 2003 or 2008?
Primary issue:
     Background: new install of LMS 3.2 on Windows 2008 sp2 Virtual Machine.
          Upgraded Campus to 5.2.1
          Upgraded RME to 4.3.1
          when updating device packages, services started extremely slow with anidbeng taking 2hrs. portal showed service unavailable.
          had to restart crmdmgtd to be able to login.
          most links in CS return the following:   Error in communicating with DCR server. DCR server may be down. Please start the DCR server           and then refresh the page.   The DCR server shows running normal.
          tried restarting crmdmgtd
          attached DCR.log
         tried CSCtd07131 .. no success

Windows 2008 offers more scalability so I would go with that although LMS has been tested on both (you will have a longer life of support as well).
When applying the CSCtd07131 patch, you need to be sure it is the right patch for the right CS version as there are multiple versions out there. However, this is fixed in LMS 3.2.1 so you should just upgrade there.
An often overlooked matter when installing LMS are the steps mentioned here:
https://supportforums.cisco.com/docs/DOC-9132
I see constant TAC cases due to installation problems because the above steps are not met or are half-met. Services starting slowly are usually an after-effect of something blocking ports (anti-virus or such) or possible database corruption. Setting DEP and anti-virus as specified above might help here, but if you did not follow these steps to the letter during this new install, I would suggest to cleanup this server and re-install properly; then move all the way to LMS 3.2.1.

Doubts in System Landscape Directory

Hello All,
I got some basic doubts in SLD.
Why do we need to store the information about the installed products and to be installed products in software catalog?
And, what is this techncal system?
After reading few help sites, what I understand is the following:
For example SAP is a product and CRM etc are the software components. We create the technical system for this product like for client 100 we create a technical system and for client 200 we create another technical system. And we give some logical names, called business sytems, to these technical systems.
My second question is, why do we need to create all these information(the information in SLD)? Why cant we directly create messages types, message interfaces etc and configure them in Integration directory without using the information in SLD like business system?
In Integration Directory, we say that the sender is one Business System and receiver is another business system. These business system are created based on some technical systems. These technical systems are based on some software components and product. This product and the software component might be a installed or non installed product. Then how do we can get the connection between the sender and the business system? Can you please explain me the idea behind considering the sender and reciever as business systems.
Can anybody please clear the above doubts?
Priya

Hi Priya,
SLD:
The System Landscape Directory of SAP NetWeaver (SLD) serves as a central information repository for your system landscape. A system landscape consists of a number of hardware and software components that depend on each other with regard to installation, software updates, and demands on interfaces.
- so talking about the working of an SLD, here if any information is required for the integration server regarding the systems(logical or physical) and the software (installed products) it refers to the SLD.
- to tell you about the other features it has....it captures the dimensions of the system landscape like solution dimension, transport dimension and technical dimension.
- putting it in short XI IS A CLIENT OF SLD

The SLD contains a Software Catalog of all installable SAP products and software components. The Software Catalog includes information about support packages and dependencies between the products and software components. This information is the basis for the description of the system landscape.

TECHNICAL SYSTEM, BUSINESS SYSTEMS, SOFTWARE PRODUCTS:
Technical system correlates the software to the physical host on which it is installed
Or in other words Technical systems are application systems that are installed in your system landscape.
- they are actually the basis for defining the business systems.
- we assign a technical system to a business system to help the SLD make the appropriate association.
- the software products used by the business system are got from the technical system definition.
- to note 1 technical system can have more than one business system assigned to it....and as told the SLD make the appropriate association between them.
