WPC search and TREX on EP 7.31

Dear all,

I have tryed following:

Configuring the Search for Web Pages - Web Page Composer - SAP Library

to configure TREX search for WPC content on EP 7.31 SP6. I was able to follow almost all mentioned steps as given:

1.)Setting TREX URL in NWA: TREX is configured already and is running. Created HTTP System like suggested with public portal url (System AdministrationSystem ConfigurationKnowledge ManagementContent ManagementGlobal ServicesSystem Landscape DefinitionsSystemsHTTP System)

2.)Defining host and alternate host for URL generator service: already configured, public resp internal portal url

3.)Configuring Default Proxy System ( System AdministrationSystem ConfigurationKnowledge ManagementContent ManagementGlobal ServicesSystem Landscape DefinitionsSystemsDefault Proxy System ): I didnt entered anything on proxy URL, since I dont use one. But I entered direct hosts like localhost, https://weburl.com, http://internal.com like suggested

4.)Configured a web site with given values ( System AdministrationSystem ConfigurationKnowledge ManagementContent Management Repository ManagersWeb SitesWeb Site ). Im sadly not familiar with the syntax of Login User Agent setting, looks a bit strange, just copy-pasted it.

5.)Created a web repository with given values ( System AdministrationSystem ConfigurationKnowledge ManagementContent ManagementRepository ManagersWeb Repository). Connected the mentioned filter, com.sap.nw.kmc.indexing.filter.IndexPropertiesFilter and created an index like descripted with property queryExtender.

6.)Configured Service Profile, Delta Indexeing, Search UI as suggested, restarted all services.

7.)Restarted the portal - found some hot deployment exceptions in the log.

8.)Created a WPC area, page, article. Published all, connected to a custom role and gave this one to my user. Works well

9.)Reindexed appropriate TREX index without any result: the number of returned documents is 0. Created a text file in /StageArea, reindexed again, still nothing. Also no errors on TREX Monitor and nothing in the NWA log, it seems the the crawler is failing on finding documents. If Im looking closer to the queue of the WPC index I cant see any documents at all, means they are not failing on preprocessing, so all counters are zero.

Also suspicious, KM navigating to portal_indexing_wr -> portal_indexing_ws leads to a "Target not available" error. No develope trace error regarding this visible. Not sure what can be expected there, the SAP Help is not mentioning any troubleshooting.

I found the SAP note 1315079 regarding a comparable issue, but it seems this one doesnt match 7.31, since I cant find an output.xml file inside of the WPC KM area using portal drive.

As far I got the idea in generally, while on 7.x it was a regular TREX index with a WPC crawler, on 7.31 the access regarding WPC content should be available through a custom web repository. However, Im running out of ideas what could go wrong. I would be glad if anybody would give me some input on this. Thanks,

regards
