Updating a TREX index synchronously

Hi,
Is it possible to synchronously update an Index after a change in a document (Portal-KM) or a record (Backend System)?
The requested change needs to be on the values at hand only and not to trigger a reindex or incremental update process.
Thanks,
Haguy

Hi Haguy,
System Administration - Monitoring - KM - TREX Monitor - Edit Queue Parameters - "Schedule Max Docs: 1" and "Schedule Type: Count". TAKE CARE, this is not adviced for production systems!
See http://help.sap.com/saphelp_ep60sp0/helpdata/en/cb/3fa73bfa3dc87be10000000a11402f/frameset.htm and below for details.
Hope it helps

TREX Indexing

Hi everyone!
Does anyone ever experienced problems with TREX indexing after installing SES?
In my project i've just setup SES and strangly Attached files are still being indexed on the old index queues and when i search for the content of the files using the TRM search it doesn't return the expected results.
Many thanks.

Hi Reddy,
TREX Queue maintains both index and deindex call entires.
Since you have deleted the ABC folder with 10 documents, it also has the deindex count of 10 .
This is the reason why you have 22 indexed documents plus the previous 10 deindexed documents.
You can check this by display queue entries and check for all synchronized documents.

Sharing TREX indexes between portal instances

Hi people,
We created several TREX search indexes in our development portal and we need to reuse them in our productive environment.
As I read in Migrating Content, changing namespace I understand that the indexes cannot be transported between portal instances.
My question is: Is there any way to access existing TREX indexes in new portal instances ?
Thanks

Hi Daniel,
of course you can use the same TREX server from two different portals.
I assume though, that the issue will be, that the resource IDs and subsequently access URLs will not be the same on the two portals. Or that, for other reasons, you will not be able to ensure abolute synchronicity of KM content in the two portals.
=> Cannot use same index for not exactly same content...
Regards, Karsten
PS: In this rough context, please also have a look at the linked thread and at the text below, concerning TREX use by totally different apps.
TRex index_service
When running several solutions against one TREX, currently you, in the project, have to ensure the following:
- availability of a TREX Server release that is compatible to all the respective solution releases (check the PPMS or PAM entries of DMS, EP, SRM, etc.)
- adequate sizing (see above link to distributed systems)
- maintenance of the proper TREX address in all solutions
AND MOST IMPORTATNTLY:
Although TREX does offer index namespaces, most solutions do not address that yet and create indexes in one common directory on the TREX Server.
Thus, if more than one of the solutions creates technical index names on the TREX Server that are likely to reoccur (e.g. "Test" is created on TREX Server with that directory name, rather than with some techID as directory name), you have to educate the future administrators/powerusers of the project to create only indexes that follow a naming conventiont to avoid index name conflicts (e.g. start all index names with solution prefix "DMS_...", "xRPM_...")
Note:
Using one TREX instance instead of several only provides "IT-side integration". It does not produce an information integration. Each solution will only search in its own indexes.
An enterprise search over KM, ERP, BI and more will be offered with the SAP NetWeaver release after 2004s.

CCM TREX indexing error

To CCM gurus,
Once in a while, I'd get indexing errors while trying to publish a procurement catalog. The errors would say something like:
1. Error when deleting TREX metadata for catalog ABC...
2. Error when creating the index for catalog XYZ...
3. Error in search index update; discarding existing changes
And then the catalog update is terminated. What we normally do is restarting the TREX server and then we can publish again.
My question is...can we resolve this without having to restart TREX each time? Is there a way to re-index TREX without restarting it?
Regards,
SN

Hi SN,
You can check the 'health' of the TREX indexes specific to CCM by use of report /CCM/CHECK_TREX (you need at least CCM 2.0 SP4 for this). In this report, if the index is either orange or red, it is not usable, if it is green it is fine. If the index is coloured red or orange, drill into this index and there will be some short text indicating what the problem with the index is. Once inside this index it can be deleted using the delete (trashcan) icon - in this case, a full publication is required to regenerate the index from fresh.
It may also be possible to use report /CCM/RECREATE_INDEX providing the index is still valid on the trex server.
Regards,
Jason

Error in updating R-tree index

Hi,
I want to update a geometry column with a R-tree index on it with a statement like:
update xxx set xxx.geometry = (select yyy.geometry...
All geometries in the updated table are NULL before. I get the following error:
ORA-29877: failed in the execution of the ODCIINDEXUPDATE routine
ORA-13237: internal error during R-tree concurrent updates: [empty-node
encountered; rebuild index]
ORA-06512: at "MDSYS.SDO_INDEX_METHOD", line 7
ORA-06512: at "MDSYS.SDO_IDX", line 86
ORA-06512: at "MDSYS.SDO_INDEX_METHOD", line 83
ORA-06512: at line 1
What's wrong?
Joerg

Joerg,
This is a known bug in R-tree indexing.
When you create an R-tree index
on a table with no geometries, it gives
this error.
This is fixed in 8.1.7.
To get around this problem, make sure
that atleast one geometry is non-null
when you create the index.
For a performance reason, it is not
recommended that you create
index on spatial table with NULL
geometries.
Updates on such indexed table will
be very expensive compared to
creating the index on a fully
populated table.

TREX indexing from content server(maxdb)

Hello.
I've installed standalone TREX on Linux, configured the connection to R3 system and to Portal as well. On the R3 I have configured connection to the SAP Content serve(via archive link) where we save some documents(pdf, doc. files). The part which I don't understand is how can I configure the repository of the content server as a source for the Trex index?
Any hint would be useful. Thanks in advance.
Vit

Hi,
the question is what exactly do you wanna do?
Integrating a archivelink in the Portal or indexing the documents via ERP?
In the first case you must create a web repository and define an index.
In the other case it depends on the SAP Solution but mostly you have to customize the SM59, SRMO, SKPR06.

Transporting KM documents and TREX indexes

Hi,
We are planning to transport KM contents with folder permissions and their asscoiated TREX indexes to a new set of EP-KMC and TREX system.
Can KM migration tool be used for transporting contents from one server to another with permissions.. Or shud we use ICE? Is there any recommended way ?
How do we transport serach indexes from one server TREx installion to another of the same version..
Any help ?
Regards
Bharathwaj

Hi Bharathwaj,
At the moment, the normal way to transport KM content (including ACL) is the ICE way. There are some known restrictions, see http://help.sap.com/saphelp_nw04/helpdata/en/e2/61701deb253242bea2ebeafa190e83/frameset.htm , but if you can live with that, it's the most straight forward way.
I'm unsure if the migration tool can do that / how easy that would be; never used it.
A real KM transport tool will be part of the next major release...
TREX indexes are not transportable at the moment. You have to re-create them on the target system.
Hope it helps

Where to update Corruption Perception Index for Customer/Vendor (3rd Party)

Hi all,
Please guide me where (tcode/function) to update Corruption Perception Index (CPI) for Customer/Vendor (3rd Party) according to his Country.
Thanks
Chan Phuong

The reason is due to the schedule line category (t.code VOV6) type CS. In the configuration, Req/assembly is switched off, so requirements will not be passed to MD04. The process itself is clear, the third party goods will not influence the plant stock, hence no need to pass the requirement.
To fulfill your requirement, you may turn on the field Req/assembly and test.

Extending TREX indexes

Hi Experts,
may I request, can anyone suggest whether it is possible to extend TREX indexes, how it is done, if it possible to extend the search interfaces for TREX in ABAP?
With unfeigned regards,
Ramana Malladi

Hi,
It seems that you have not the actual TREX version and there is some database incompatibilities.
Download the actual version from service.sap.com:
TREX 6.1 for Search and Classif. (TREX) (From SP000 To SP025 or higher (Recommendation: SP027))

Portal Search Not Working - Only Returns Portal Content, Not TREX Indexes

I have configured two indexes using the portal. One is for documents that reside on the portal, and the other one is for a website that we have configured in TREX using Cruiser. The TREX Admin console shows that the website information has been indexed. However, when I search on a word in Portal, only the portal contents are displayed. Is there a different search field for looking up TREX/indexed files? I'm using the search field that's on the front page of the portal. Also, both indexes belong to the same index group. I did use the serach feature built-in to TREX Admin to verify that there were documents stored in the index.

Please check Below Link

Where are TREX index stored? TREX server File system? or KM repository?

hi, friends:
can someone tell me where are TREX index stored ?
in TREX server file system?
or in portal KM repository? file system or DB?
thank you
Carol

Carol,
TREX is a separate product. During installation and configuration of TREX you connect it to the portal. The search iViews of the portal will use the configured TREX server to do the actual search:

Searching TREX Index through Web Dynpro

Hi experts,
I'm trying to search through my TREX indexes with Web Dynpro. I have found some sources on this website and they seem to work, but when I test my Application, the table I want to fill stays empty.
The strange thing is that the "getNumberResultKeys()" variable is returning a correct value, but that the "ISearchResultList" stays empty.
I'm a newbie in Web Dynpro, so any help will be appreciated!
I wrote the following code:
     try{
          com.sap.security.api.IUser nwUser = UMFactory.getAuthenticator().getLoggedInUser();
          com.sapportals.portal.security.usermanagement.IUser user;
          user = WPUMFactory.getUserFactory().getEP5User(nwUser);
          ResourceContext resourseContext = new ResourceContext(user);
          IIndexService indexService = (IIndexService)ResourceFactory.getInstance().getServiceFactory().getService ( "IndexmanagementService");
          IFederatedSearch federatedSearch = (IFederatedSearch)indexService.getObjectInstance("federatedSearchInstance");
          List indexlist=indexService.getActiveIndexes();
          SearchQueryListBuilder sqb = new SearchQueryListBuilder();
          sqb.setSearchTerm("SomeSearchTerm");
          IQueryEntryList qel = sqb.buildSearchQueryList();
          ISearchSession session = federatedSearch.searchWithSession(qel, indexlist,resourseContext);
          ISearchResultList results = session.getSearchResults(1, session.getTotalNumberResultKeys());
          ISearchResultListIterator iter = results.listIterator();
          while (iter.hasNext())
          ISearchResult result = iter.next();
          IPrivateDetailView.IPracticeDataElement PracticeData = wdContext.createPracticeDataElement();
                                        PracticeData.setContentSnippet(result.getContentSnippet());
                                        PracticeData.setResource(result.getResource().toString());
                                        wdContext.nodePracticeData().addElement(PracticeData);
     } catch (ResourceException e1) {
                    throw new WDRuntimeException(e1);
     } catch (UserManagementException e2) {
                      throw new WDRuntimeException(e2);
     } catch (WcmException e3) {
                    throw new WDRuntimeException(e3);
Thanks in advance for you help,
Edwin

My context:
value node - PracticeData
value attribute - Resource
value attribute - ContentSnippet
The results are written to the context here (inside the while - statement):
IPrivateDetailView.IPracticeDataElement PracticeData = wdContext.createPracticeDataElement();
                                        PracticeData.setContentSnippet(result.getContentSnippet());
                                        PracticeData.setResource(result.getResource().toString());
                                        wdContext.nodePracticeData().addElement(PracticeData);
I created a table with databinding to the value node (and value attributes).

Hi there,
I just read this thread, and maybe someone here can answer my current trex question:
I have created an ordinary CM repository, and created an index with this repository as source. Now the problem: I would like to exclude files in the repository with specific mimetypes from the TREX indexing process.
I have verified that the TrexValidMimetypes.ini does not contain any reference to the Mimetypes I'm creating, but never the less, the document titles are searchable and are returned when searching.
How do I get around this issue?
Is it possible in NW04 or EP6.0 SP3 PXXX??
Regards,
Hco

How does BDB update its secondary index?

I am asking how does Berkeley DB update its secondary index?
For example, in a BDB table with key value pair ``<k,v1>``, the index database would have reversed pair like ``<v1,k>``. Upon an insert (or essentially an update) ``<k,v2>``, base table record ``<k,v1>`` should be overwritten to ``<k,v2>``.
But how would BDB deal with ``<v1,k>`` in the index table? Will it delete it immediately?

Hi,
As long as you correctly open the primary database and secondary index database, and associate the secondary index database with the primary, any update on the primary database will be reflected in the secondary index.
For more information, please refer to Reference Guide for Berkeley DB -> Chapter 3. Access Method Operations -> Secondary Indexes section.

Cindy Zeng

The location of the TREX index file?

Experts:
Would you please help tell us where is the TREX index file located and is it a TEXT file?
Thanks!

Hello Ashley,
on our System (Unix server, trex only) the index files can be found at \usr\sap\ET0\TRX00\... Numbers dependet on the actual instance number. And itu00B4s probably a little more complicated than "one" Text file...
maybe this helps,
regards, Bastian
