TREX: Preparation Failed in document index

Hi,
I have defined an index with one datasource and I get an error in 317 documents, while 204 documents are OK.
Error are due to 6401 code error (HTTP Status Code 401 : Unauthorized) but I don't know how to solve it. Everyone has full control to datasource (is a development environment).
Any suggestion?
Thanks and best regards!

Trex: Preparation failed: index operation

Hi gurus,
We have a Trex 7.0 server working on a seperate server. When I look at Index Administration, the statuses of the indexes are all green. But when i look at the indexing monitor, one of our indexes is in red status, It says Indexed:13342, Errors: 15610.
When I click on the Errors link, It says: "Trex: Preparation failed: index operation".
I searched the trace files but couldn't find sthg useful.
Any suggesstions?

Hi Tolga,
please check your installation with the information mentioned by Jochen Goeeninger (long post) in the following thread Trex HTTP Server not seen in Portal
Furthermore try to open one of the documents you are trying to index via HTTP from the TREX Server.
With the result of that, I would suggest to open support message under http://service.sap.com/message
Hope this helps,

TREX Preparation Failed exception

Hello All,
I am facing an issue with TREX wherein the documents not being indexed properly.
The TREX monitor shows all status as green but when I check the 'Display Queue Entries' from
System Admin -> Monitoring -> Knowledge Management -> TREX Monitor, I see a message as:
Return Code = 6500
Return Message = HTTP Status Code 500: Internal Server Error
Document status = Preparation failed.
Please guide me to resolve this.
Awaiting Reply.

Hello Martin,
Please excuse me for my late reply.
I created a test repository, created an index for it called Test_Index, attached it with a KM Data Source, uploaded 3 .txt files. All these txt files have size within 10 KB.
1. When I search using this Test_Index, it does not return any txt file. There are few indexes, so I selected my index to search.
I could successfully open the text file on the browser.
2. Checked DefaultTrace logs and found exception related to another index. Details are:
TaxonomyNamespaceManager.getChildren: Error because the index with name Rama_test1 is not available. Probably you have to delete old taxonomy data in the taxdata repository - com.sapportals.wcm.WcmException: index with index id Rama_test1 doesn't exist!
But 'Rama_test1' index does exist. It is available when I click on 'Show Options -> Search Scope'
on Search page.
3. We also have an index which is connected to 'Livelink' system.
I get an exception for this, saying - the repository returned no root collection (null): livelink
4. com.sapportals.wcm.repository.IOErrorException: sending PROPFIND to remote server
at com.sapportals.wcm.repository.ResourceException.fillInStackTrace(ResourceException.java:399)
5. Lastly, I see an exception with severity=fatal saying:
exc: /SalesManual - com.sapportals.wcm.repository.InvalidUriException: Invalid RID: No repository manager found for prefix: /SalesManual
* at com.sapportals.wcm.repository.ResourceException.fillInStackTrace(ResourceException.java:399)*

Any ideas on these?

TREX: Preparation Failed with return code 14047

Dear all,
For files bigger than 15 MB Indexing is not happening. Document status is "Preparation Failed".
We are on EP 7.0 SP 16, TREX 7.0.
How can we solve this problem?
Best Regards,
Aparnna Prasad

Dear Aparnna,
please check the version of the TREX you use (file TREXVersion.html). If the TREX is older than Rev 30 update to the newest one because of the new filters version.
Correct the following:
go to the /usr/sap/<SID>/TRX<Nr>/exe (you need to set the TREX environment with TREXSettings.sh first) and execute :
filter.x <file name> <otuputfilename.htm> for example:
filter.x /path/to/file.xls /path/to/file.xls.htm
What's the size of the output file? If it's more than 20 MB
please increase parameter maxfiltersize (TREXFilter.ini) and index document again.

Tushar

TREX preprocessing failed, HTTP Status Code 401

Hello everybody!
I'm using SAP NetWeaver 7.0 (2004s), TREX 7.0 on Win2003 Server.
I'm trying to index files, but it doesn't work for files bigger than 10KB. I know that for these documents > 10KB only the URI is transmitted to TREX. So it seems the problem is based on the communication between TREX and portal.
Error messages:
TREX monitor: preprocessing failed, error number: 6401, error message: HTTP Status Code 401: Unauthorized
Indexmonitor: Trex: Preparation failed: index operation
- all TREX server status icons are green.
- I'm not using any SSL communication.
- indexing doesn't work for any data sources, neither web repositories nor KM content.
- I've checked the host and alternative host parameter in the URL generator service (both http://<myservername>:50100).
- I am able to access the URL of the resource directly.
- I've added the "unescape_url=no" entry in the TREXPreprocessor.ini like SAP Note 650521 says.
- my system ID is properly set.
- the password of user index_service does not expire.
Does anybody have any further ideas?
Many thanks in advance
Steffi, working on it for days...

Hello Robert and Steffi,
With the help of SAP support, I could solve the problem !
Certificate for SAPLogonTickets had expired, so authentication was no longer possible. Solution : recreated the certificates with Visual Admin.
In Visual Admin, go to "Key Storage" service, then choose "TicketKeystore" view.
Delete SAPLogonTicketKeypair and SAPLogonTicketKeypair-cert certificates (or rename them in a first time).
Then recreate "SAPLogonTicketKeypair" :
- fill the Entry Name with "SAPLogonTicketKeypair",
- fill "Common Name" with the value from the previous ticket
- check "Store Certificate" (this will automatically create SAPLogonTicketKeypair-cert)
- choose "DSA" as Algorithm
and click on "Generate"
That worked fine for us on two platforms.
Hope that gonna help...

Preparation failed: Indexing error

Dear All
We have one file system repository on which an index has been created and data sources and Taxonomy created. When we search for the documents in the repository , it says "No documents found" .
If i check the "Indexing Monitor" ,there is a "Preparation failed error" for the Index with return code "Preprocessor: failed".
Another index created is working fine.
Can you please let me know if i am missing on something and how to go about solving this error.

Trex Monitor - Preparation Failed

Hi,
I have configured a file system repository that I'm trying to index. I have installed KM Pack 3, and the crawler is working fine. But in indexing all the documents fail. Here are the queue details, same for all documents.
Return Code: 13502
Return Message: HTTP-Proxy: BadGateway
Document Status: Preparation Failed
Action: Index
Retry Count: 3
The repository seems to be working, as in I can access the files of the repository from the KM Content Tab.
Any ideas as to what am i doing wrong?

Hi guys, I'm getting this error from the crawler. Any ideas at all what might be causing it?

Hi,
Please check if adding more disk space to the location of the Index Partition could resolve the issue.
Here is a thread with similar issue:

Then reset the index and start a full crawl.

What is the source of this Crawl Error `The item could not be indexed successfully because the item failed in the indexing subsystem`

Once in a while my full-crawl fails and stops working properly. The crawllogs show this error for all items crawled.
The item could not be indexed successfully because the item failed in the indexing subsystem. ( The item could not be indexed successfully because the item failed in the indexing subsystem.; Caught exception when preparing generation GID[7570]: (Previous generation
(last=GID[7569], curr=GID[7570]) is still active. Cannot open GID[7570]); Aborting insert of item in Link Database because it was not inserted to the Search Index.; ; SearchID = F201681E-AF1B-45D2-BFFD-6A2582D10C19 )
The full crawls starts out ok, after a while (1.5 hours into the process, 50% of all the data) suddenly no more items can be added to the index.
The index seems to be stuck. The index files on disk are no longer updated (Located in D:\Microsoft
Office Servers\15.0\Data\Office Server\Applications\Search\Nodes\BAADC4\IndexComponent3\storage\data\SP4d91e6081ac3.3.I.0.0\ms\%default) The Index and Admin component start to report these error in the ULS logs:
NodeRunnerIndex: Journal[SP4d91e6081ac3]:

Exception invoking index cell I.0.0. Retrying in 16 seconds: System.InvalidOperationException: Illegal state transition in SP4d91e6081ac3I.0.0.FastServer.FSIndex: Rollback -> Rollback
Looks to me the index has troubles updating/merging 'generations'. But the exact working of the indexer is not documented (as far is I know). Let alone how to fix this.
Other (maybe related) observations
Just before the errors start the NodeRunnerIndex starts a 'checkpoint': Journal[SP4d91e6081ac3]:
Starting checkpoint because forceCheckpoint is true.which ends a few moments later with Journal[SP4d91e6081ac3]:
All journal users have completed checkpoint Checkpoint[7560-7569].
Also just before the errors start to appear a TimerJob starts: Name=Timer
Job job-application-server-admin-service. This timerjobs does some strange things to the search topology: Synchronizing
Search Topology for application 'Search Service Application' with active topology [...] and Activating
components. Previous topology: --- New Topology: TopologyId: [...] followed by Starting

And right after these two evente the errors start to occur. (each row is a ULS log enrty)

The Question What is causing this? And how to prevent it? It happend twice in two weeks
nows. Out of the blue, no config change has been made, all disks have enough space.
Known Fix This resolves the problem, but doesn's address the root-cause of the problem!
Stop all crawls.
Wait a few minutes to let the crawl come to a complete stop.
Reset the index (clearing all!)
Start a full-crawl. In the meantime no search is available to the end user (boohoo!)

Hi,
I searched for the similar error log, the issue is finally solved by adding more drive space even though they though there is plenty space already.

From your decription, the issue seems to occur to your full crawl. There is one point in best practise for crawling:
Run full crawls only when it is necessary, the reasons to do a full crawl are as below:

In Trex where does the documents reside ?

We have Enterprise portal and use TREX for collaboration rooms and document indexing. EP is a java only Netweaver stack on AIX and TREX is on a window box. What I wanted to know is where do the actual documents, which TREX indexes reside?
Does Trex retain a copy of the indexed document? For a particular index where is the mapping of the actual document? Where can I look at all this data?
Pls advise.
thank you
regards
Laxmi

Hello Kai,
documents original location is transparent on KM, whether it is on a external repository or not doesn't matter,
for KM and TREX it is part of repository manager (configured at System Administration > System Configuration >
Knowledge Management > Content Managenement > Repository Managers).
Once a repository manager is activeted, there are several services running on top of it, eg.: subscription, rating,
etc. and other global services which affects every repository. Crawler service and Index Management are the
global services which will do indexing work
In fact TREX doesn't look for documents, the crawler is the component that retrieves the documents and
deliver for TREX. Have in mind that the crawler is part of KM, not TREX. It is active for every repository,
you can check on the monitor at System Administration > Monitoring
for more information: http://help.sap.com/saphelp_nw70/helpdata/en/fb/38ef207d0a47ee9dc08deeed855392/frameset.htm
once documents are retrieved by the crawler and is at TREX hands, it will index normally, it uses
a file system based architecture, if you browse through TREX server you can find the indexes you have
created as folders and documents information inside. Be careful when checking at file system level, data
there is designed for TREX work only, it doesn't serve as backup and can't be considered for any
other functioning.
kind regards,
Rafael

Crawling fails for UME index

Dear friends,
I have setup an index for the ume/users directory. The crawler fails to crawl all entries for ume/users. Do I need to setup my own crawler for the ume or is the standard crawler supposed to work? Can someone, who has got the crawler to work for ume, share his ideas here.
We are on EP6 SP13.

Can't open my IBA project: error parasing document index: invalid character in attribute value

Hi guys,
I am new of iBooks Author and I am not HTML code savvy (expect the very basics). I have to send an iBooks for an University exam and I can't open my file anymore.
I was working on it since Saturday, I saved many times and I have quit the iBooks Author and rebooted my iMac few moments ago. There were no crashes.
The project is a iBook with pictures, videos and some Tumult Hype animations. It is 248Mb.
Now I can't open the file (but I can see it in quick view). The error message is in the subject, but here it is again:
"Progetto iBooks" couldn't be opened. Error parsing document index: invalid character in attribute value.
Now, I have to send the project today (here in Italy it is now 7:10 am) and so I am kind of desperate.
Any suggestion?
I am already working on making a new ibook, but if someone could give me a workaround to fix it and open it on iBooks I would be extremely grateful.
Best regards,
Sebastiano

Hi Sebastiano,
Did you ever get any answer? I have the same problem and now have to work from an old version again (good thing I had backup one manually!)
Thx

Migration Report Errors- Failed to map index

I am very new to oracle and databases, so my terminology is limited. Could someone explain to me what this means? And if possible, a suggestion as to how should i go about to rectify this error.
<<<"Failed to map index :
Column list specified is already used in an existing index. This index will not be created.">>>
This occured when i captured the database from MySQL to OMWB during the truncation to Oracle.
Any help will be greatly appreciated. TIA
Andrew

Hi Andrew,
What this message means is that the index that is failing to create is doing so because there is no need for it. This is because there is already an index created on the same columns.
If you need any more assistance then please e-mail [email protected]
