FS Repository Manager depth limits - crawling problems

Ciao a tuti.
I have some really strange results from my Crawler. Here is the story:
After Crawling 50000 for indexing I have around 800 docs where I have the Error Type: crawler.
The interesting thing is that these documents have nothing in common & even via PCD there are "there" but after clicking on it, the message says: the document does not exist.
So where can I start with the research? Maybe out there has someone a good idea?!
Originally I thought, that I have a problem with the depth of the file structure, cause the structure is reallly complex. On the other hand I could not found any limitations for the FS Repository Manager.
Thanx in advance

Sir or madam -
First, you may be hitting a URL limit of 256 characters. Are you using the /irj/go/km/docs path to access the documents, or are you using the old method?
Second, if you create a CM repository with FSDB persistence, do you have the same issues?
Third, how deep into the repository does it go before an error is thrown? Have you tried creating a test index directly to the folder/document in question?
Good luck!

Searching problems when implementing my own repository manager

Hi there,
i've serious problems to get the search fuctionality for my own repository manager running. I'm using the 'new', Netweaver-based api.
Always if I'm launching a search I receive a ClassNotFoundException in the follwing context:

I'm using EP 6.0 SP2 directly installed from the CD
#51 020 549 without explicit installation of any patch or hotfix; the portal itself shows the version number 6.0.2.0.0 (implementation version 6.2.0.0.200310100950).
I switched on logging but I never reached the INamespaceManager's methods isQueryPropertyNameUnderstood() or getQueryBuilder().
So I figure that this might a problem of my (too old?) unpatched version of EP6????
What can I do to get the serach func running?
Thanks for your support,
Daniel

Hi Karsten,
thanks for your annotation.
Does it mean that I HAVE TO apply at least Patch 4
to get the search working or SHOULD I apply the patch to be up-to-date and look for an error in my code???
Thanx a lot,
best regards,
Daniel

Problem in copyResource()-Repository Manager,ClassCastException

Hi,
I have written a read-write custom repository manager from the sample downloaded from sdn(A kind of extension of SimpleRepositoryManager).
I tried to implement the ImutableNamespace opertion copyResource(IResourceHandle handle, ICopyDescriptor copy) with supported option COPY_DEEP and COPY.
It really does a copy to the destination directory but after that it throws a ClassCastException
for com.sap.netweaver.bc.rf.common.Rid;some how my feeling is its failing either in findResource or lookup after copy.
For detail exception pls see below(from EP KM Iview-call stack)
System Error
An exception occurred during the program execution. Below you will find technical information pertaining to this exception that you might want to forward to your system administrator.

The CM repository in mode FSDB keeps the namespace structure of the repository in the database just as it does in the other modes. Any change is done parallel in the file system and in the internal database.
Since we have mode FSDB and the file system might change at any time by external processes, there is a component called synchronizer that checks with every lookup if the file system and the internal structure are still in sync. To determine this it looks at the modification date for folders and at modification date and size for plain files.
If any of these do not match then the synchronizer overwrites and modifies the internal data to reflect again the status of the external file system.
Now in your portal the synchronizer itself is working OK. That's because your repositories run fine locally.
With your remote file systems I can think of some possible explanations.
The caches might deliver responses after immediate file system changes. We ruled out this one already.
The synchronizer might not recognize the changes in the file system's meta data. This is why I'd like you to try and compare the behaviour of the file system repository, see above.
The synchonizer might run into some error when it tries to access the remote file system. This should be visible in the logs.

Problem with CM repository manager in FSDB mode

Hi all,
I have configured a CM repository in FSDB mode.The file system which is configured in the CM repository manager is on a network and not on the Portal Server. The problem that I am facing is as follows -
1. When i create the file manually in the file system , the file does not appear in the KM Content.
2. When i create the file from KM, it's created in the file server and now the previously create files in 1, are also visible.
3. When I delete the file from the fle server , I am still able to see the file name in KM content, but when I click on it it says resource not found.
I tried everying from clearing the cache to having no cache entries, but nothing seems to work.
Please help, I am really stuck with this.
Will definitely reward points for helpfull answers.
Thanks in advance,
Vivek

SOAP/Web service based repository manager

Hi,
We would like to implement a repository manager using SOAP/Web service messages to connect to the document store. The solution will have to support most opperations as the WebDAV repository manager supports. TREX has to be able to crawl for indexing/classification, but I guess that is not a problem.
Is the some information out there on creating repository managers like this, and how they tie in with ACL managers, cahces etc?

Language Issue in Repository Manager and T-REX

Hi Everybody,
we are trying to implement a repository manager for SAP KM. Our systems stores documents language specific in a database. Now we are wondering how we should create a view to the documents, so that every document in each language is indexed by T-REX correctly. Lets say the internal view is something like this:
   /Documents
      ->File.pdf
/Images
      ->Image.jpg
In this case File.pdf and Image.jpg can exist in different languages. So our question is, does T-REX create an index for each language available in the portal? If so, which would be very nice, how can we get the current language T-REX is using for indexing within our RM implementation?
Otherwise we have to create virtual TOP-Level laguage folders for each language in our database that would look like this
/de
   /Documents
      ->File.pdf
/Images
      ->Image.jpg
/en
   /Documents
      ->File.pdf
/Images
      ->Image.jpg
We try to avoid this, since File.pdf ist a single item with different language versions.
Does anybody know the best way to solve this?
Kind Regards,
Ali

Hi Matthias,
I think the language handling and the mapping of default languages is application specific and should be done within the RM. In our case this available allready, since our WCMS system allready take care about that... So for a logged in user, we are able to create a language specific folder structure very nicely.
Our problem is the indexing by TREX. We wan't to make sure that every language version of the docment can be found when people searching. So in our case the perfect solution would be that TREX asks the RM for available languages in the repository and starts a crawler for each language available in the repository.
Something that I am not sure about is the presentation of the search results. Since the URL of the search result might point to a different language version than the logged in user has. So if the URL is
http://server/irj/go/km/repsotory/Documents/File.pdf
this might result to a german document, even if the searched term is in the english document. So the language must be set in the search result. For example like this
http://server/irj/go/km/repsotory/Documents/File.pdf?locale=en
This would be our preferred way to handle this issue. I think we will keep the virtual language folders until the new feature is available.
Thank you guys for this very high quality answers )
Kind Regards,
Ali

WebDav Repository Manager Disappears???

Hello,
I am seeing some strange behavior with an IIS WebDAV based KM WebDAV repository manager I created. I used the following as a basis for my setup.
http://help.sap.com/saphelp_nw04/helpdata/en/4a/217fb6c33c6748a1715a161ac942cd/frameset.htm
I created the memory cache, CM HTTP System, a portal system aliased with the same ID as the CM system, and finally the WebDAV Repository manager. If further setting detail is needed I can send that. The repository worked on Friday. It is not there today. This has happened twice. When I drill down into Content Administration > KM Content>root > runtime > Repository Managers... > IISWD > servers I am presented with "hostname". When I select Details>Properties>Miscellaneous tab I see failures.
Example:
last-failure-1: 2007-07-16T20:12:14Z: PROPFIND /ExternalPortal: com.sapportals.wcm.WcmException: sending request to: http://hostname/ request uri: /ExternalPortal unable to connect to hostname: unknown host: hostname (java.net.UnknownHostException: hostname)
All of the required KM objects mentioned before are still present and configured as they were a few days ago. Is my repository loosing it's reference to the CM HTTP System.? Has anyone seen this before?
Thanks,
Doug

Hi Doug
I believe the problem is that your HTTP System in the portal cannot see the share you are trying to integrate into the potal. Is it a webdav-share set up using an IIS?
I have tried to implement the WebDAV/SSO solution where we got the same error for no reason. But after installing some different hotfixes (http://support.microsoft.com/default.aspx?scid=kb;en-us;893246, eg) and changing server to a standalone IIS, the error didn't occur any more.
Hope that can give you some ideas.
Kind regards,
Martin

Unable to create File System Repository manager

Hello,
I would like to create File System Repository manager to this path: I have mapped a certain Network drive "
main-uni-fs1\pictures$" to the Portal Machine and under this machine it appears as drive "N:\", inside it there is a picture folder which I would like to create the mapping to. I tried setting the "Root Directory" value to "N:\" and to "
main-uni-fs1\pictures$" but I keep receiving an error message at the Repository Component Monitor (see below).
10X,
Roy

Hello Roy,
1> Create a new path that points to the pictures directory on the system. Enter the path lik
mypc.myorg.com\pictures
Under Sys admin -> Sys Config -> KM -> Content MGT -> Global Services -> Network path
Under the user name and password, enter your username and password
username whould be entered like domainname\username
2>Then create a system in for the mypc.myorg.com server under
Sys admin -> Sys Config -> KM -> Content MGT -> Global Services -> System landscape definitions -> System -> Windows Sytem.
(Assuming u are acessing a windows sytem from a portal running on windows platform).
You need to enter system id and description . Kindly remember the system id, since it would be useful in two places while usermapping and creating the file system repository.
3>create a file system rep mgr under
Sys admin -> Sys Config -> KM -> Content MGT -> Repository Managers > File System Repository
Following properties are most important.
Name , ACL manager cache, Security manager(which you would have to set to W2kSecurity manager)
prefix(this is the folder name that you will identify your repository with) Widws landscape System (this is the sytem id of step 2) and root directory (network path of first step only in this case enter it like this //mypc.myorg.com/pictures)
4>Then under user mapping section, you will find you system (the system id of second step) , enter your name as password.
Initially when you configure your rep manager, you dont need to start ur servlet engine. If you modify any property then you need to re start ur servlet engine.
These are the steps for creating repository
If this still does not get resolved. Then kindly read the limitations of creating the file system repository manager in the link that I had posted in my earlier post.
Thanks and Regards

BOE integration in SAP NW Portal via repository manager and km content

Hi BO XI experts,
we try to synchronize a BO folder of BO InfoView through the KM Content in SAP Portal. Following the instructions of the book "Integrating SAP Business Objects XI 3.1 Tools with SAP NetWeaver", we
- installed the system under System Administration --> System Configuration --> System Landscape
- checked settings in the web.xml file
- integrated a Crystal Report through upload and apply of the par-file com.BusinessObjects.pct.masteriview.par
--> the iView for a specific report contained in the InfoView works fine
- integrated the par-file BusinessObjectsKM.par
- created a new Business Object Repository Manager through System Configuration --> Content Management --> Repository Managers --> Business Objects Repository with a new prefix
- went to Content Admin --> KM Content and tried to open the new repository with this prefix
Before upgrading our systems with EP 1 for NW 7 (and EP 4 for SAP ERP 6) this repository worked fine.
After this, we encounter the following error and cannot open InfoView content anymore:
System Error
An exception occurred during the program execution.
Exception Message: Your operation cannot be fulfilled due to a network problem, please try again.
Go back and try again
The SSO connection seems to work fine as the a single Crystal Report can still be opened through the iView.
Does anybody have an idea how to solve this problem?
Thank you very much in advance.
Best regards,
Carolin

Hello Ingo,
thank you very much for responding so quickly. Yes, I tried it with a new BO repository but without any changes. I also repeated the upload of BusinessObjectsKM.par - file.
I'm wondering about the result of my system connection test of the BOE system.
There I get the message:
Retrieval of default alias successful
Connection failed. Make sure that Single Sign-On is configured correctly
As the Crystal Report iView works correctly and therefore SSO is supposed to be installed properly, I do not understand why we receive this message. Could the problem, in spite of the crystal report working fine, lay in a uncorrect system configuration?
Before, when the repository worked properly, I did not verify the connection test.
The enhancement packages should not have had any impact on our BO installation.
Thank you for your help.

Help needed: Search function for custom Repository Manager

Hi there,
i'm writing my own Repository Manager for EP 6.0 SP2 PL4.
I've serious problems getting the search function running. I'm using the 'new', Netweaver-based API.
I think, there are some general questions to answer:
- My Repository Manager exposes lots of custom
   properties to the system. I create the properties
   for example using following code:
   IProperty newProp = new StringSingleValueProperty(
     PropertyName.getPropertyName(
              "{}" + myAttName),
     myAttVal,                         PropertyFlags.constructFlags(
              true, false, true, false)
    Is there any convention for the propertie's name?
    I think it has to be written in lowercase only?
    Can I use ANY namespace I want instead of the
    empty default namespace? (For example:
- After indexing my resources (of course, containing my
   custom properties), the TREX-Monitoring screen for my
   index shows all my custom properties in the 'Document
   Properties' area, but all uppercase chars are escaped
   somewhat. Is this OK?
- Trying to use the index above to search for particular
   resources in my repository by my custom properties
   fails all the time ('no docs found...'); searching for
   any system property works fine. What's the reason?
- How can I force the (Property-) search uses my
   custom namespace-manager's methods
   isQueryPropertyNameUnderstood() and
   getQueryBuilder()
   to perform a 'pure' property search by the repository
   manager? It seems that the TREX always handles the
   queries by itself, because my methods are never called.
Thanx for you help,
Daniel

I created a new manager and copied the classes exactly from the "simple" example and I see similar behavior. Actually, when I do this, folders are recursively copied, but not files. Again, browsing and viewing of files work fine. Again, I am not seeing any unexpected exceptions.
The only thing that changed were the names and namespaces. Nothing else at all was changed.
This makes me think I am missing some configuration somewhere or there is something special about the example project that the wizards are not creating. The only difference I see in the project file is an additional nature (com.tssap.selena.cmf.PatternNature), but I am not sure that is relevant.
Wow, I am really stumped.

How to control permissions in KM using File System Repository Manager

Hello everybody
I have a scenario with 15+ file servers which content needs to be mapped into Portal KM as read-only.
Windows Authentication is configured on the portal, so the users don't need to supply the portal with username/password.
Now the users are of course only allowed to see the same content in the portal as they can see on the file servers. I know that the permission mapping can be done using a File System Repository Manager with W2KSecurityManager, but in that case the users will have to maintain the mapping of rights from windows to portal manually. And with ever-changing passwords this is too big an administrative task. So I am looking for another solution.
My question is therefore:
How can you configure the File System Repository Manager in a way where it the user does not need to maintain "user mapping" manually, but only need to logon to the portal (through windows authentication) and can see the same files from the portal as he/she can see from the file servers.
Can this information in some way be taken from the configured Windows Authentication? Or is the only solution to enable WebDav on the file servers and and follow the "Integration of Windows File Servers into the SAP KM platform Using SSO and the WebDAV Repository Manager"-guide?
Any help will be rewarded.
Best regards,
Martin Søgaard

Hi again Dirk
I just studied the "Integration of Windows File Servers into the SAP KM platform using SSO and the WebDAV repository manager"-guide in depth and I don't quite understand what rights the cmadmin_service and notificator_service are supposed to be given in the Active Directory. In the guide it says:
"A number of global services and repository services need to perform operations on resources in various repositories. For example, the index management service must read all resources it is meant to index. When an index is created, the service user index_service is used. Therefore, this user has to have at least read access to all repositories that are to be indexed. Other users that are used by the SAP KM platform are the service users notificator_service and cmadmin_service. When a search is taking place, it is the user that is currently logged on to the portal."
I dont quite understand what the two service users are doing but more importantly, I need to give the two service users the correct permissions in the Active Directory (or through user mapping). I understand that index_service only needs read_only permissions, but what permissions should the cmadmin_service and notificator_service be given?
Best regards,
Martin

Possible reasons for a repository manager not displayed under KM Content

Hi,
I developed a repository manager and deployed the par file Archive uploader.
Most time after deployment, I can see immediately an instance of the repository manager under KM Content. However, sometimes, when I made some changes to the code, it doesn't appear under KM Content. The deployment log in SYS/global/config/cm/reports shows no error.
I tried to find some log in System Administration - Monitor, but found nothing.
So, could anyone tell me:
1. What might be the reason for the problem that the repository manager cannot display under KM Content after deploying the par?
2. Where can I find the log explaining why my repository manager cannot display?
Thanks,
Ray

Hi Ray,
Deploying a repository manager means a hot KM deployment, which isn't supported at all, see https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/bb1f18be-0801-0010-ffa0-e3495f7401bc and SAP note 894884. After such a deployment, the KM is restarted, but you have some kind of "shadow KM" in memory, which leads for most things to an unpredictable behaviour.
In contrast to the documents reffered to above, also the standard KM delivery from SAP still behaves in an uncontrolled way for many issues.
That's why after a KM hot deployment, you should restart your server if you realize anything "unusual". A workaround is to debug your code and using the hot code replacement feature (which only works in some situations, but that's better than nothing...).
Hope it helps

Web Repository Manager and robots.txt

Hello,
I would like to search an intranet site and therefore set up a crawler according to the guide "How to set up a Web Repository and Crawl It for Indexing".
Everything works fine.
Now this web site uses a robots.txt as follows:
User-agent: googlebot
Disallow: /folder_a/folder_b/
User-agent: *
Disallow: /
So obviously, only google is allowed to crawl (parts of) that web site.
My question: If I'd like to add the TRex crawler to the robots.txt what's the name of the "User-agent" I have to specify here?
Maybe the name I defined in the SystemConfiguration > ... > Global Services > Crawler Parameters > Index Management Crawler?
Thanks in advance,
Stefan

Hi Stefan,
I'm sorry but this is hard coded. I found it in the class : com.sapportals.wcm.repository.manager.web.cache.WebCache
private HttpRequest createRequest(IResourceContext context, IUriReference ref)
 HttpRequest request = new HttpRequest(ref);
 String userAgent = "SAP-KM/WebRepository 1.2";
 if(sessionWatcher != null)
 String ua = sessionWatcher.getUserAgent();
 if(ua != null)
 userAgent = ua;
 request.setHeader("User-Agent", userAgent);
 Locale locale = context.getLocale();
 if(locale != null)
 request.setHeader("Accept-Language", locale.getLanguage());
 return request;
So recompile the component or changing the filter... I would prefer to change the roberts.txt
hope this helps,
Axel

Is it possible to do massive Delete of Revisions with Repository Manager

Hi,
I use UCM 11g.
I am planing to delete all the revisions that have the ContentType "DataSheet". That is about 10.000 revisions. I did start the Repository Manager and filtered all the content for ContentType "DataSheet".
My problem is that I can delete only 200 items at a time, cause Repository Manager is showing me only the first 200 revisions. This is very time consuming.
Is there another way to do this?
Thx
Tobi

Use Archiver...
Define your export query to cath all the 'Data Sheet' items
make sue that you choose the option for All Revisions
Then when you choose Export from the Actions menu tick the checkbox to delete items after export
This way they will all be deleted and you will still have a handy back up of them in Archive on the file system - so if you need to you can restore.
