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?
Tolga

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,
Robert

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 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.

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)*
Location: com.sapportals.wcm.service.reporting.walker.HierarchyWalker
Any ideas on these?

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.
Regards
Jayesh

Hi Jayesh,

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.
Regards,
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...

TREX is not indexing certain excel files

Hi Experts,
TREX is not indexing certain excel-files correctly. I get a "no message found error" (14047) Trex: Preparation failed: index operation by certain excel files - but not by all. I found out what they have in common: some have filters activated and some have a lot of columns or rows.
Is there any way to avoid these errors and index them correctly?
TREX: 7.0.47
Portal: 7.01 SP7
Thank you in advance
Best Regards
Norman

Hi Norman,
Did you review note 1528705? It has a fix for this issue.

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?

Can't rebuid index for failed index

Hi,
I got a kind of indexing failure for certain reason, for example, using too long name of dot-notation to specifying a object attribute for indexing. Then I drop the failed index by the following statement:
drop index myIdx force;
Then try to re-create the index:
CREATE INDEX myIdx on test(Descp.FUNC_SUM.FNAME)
indextype is ctxsys.context
parameters ('datastore ExpSeq_Summary_Dir
filter ctxsys.null_filter');
At this time, the following error happened:
CREATE INDEX ESIdx on test(DESCP.FUNC_SUM.FNAME)
ERROR at line 1:
ORA-29855: error occurred in the execution of ODCIINDEXCREATE routine
ORA-20000: interMedia Text error:
DRG-10516: failed to perform DDL operation due to an Oracle error
DRG-50857: oracle error in driddl.PolicyCreate
ORA-00001: unique constraint (CTXSYS.DRC$IDX_COLSPEC) violated
ORA-06512: at "CTXSYS.DRUE", line 126
ORA-06512: at "CTXSYS.TEXTINDEXMETHODS", line 78
ORA-06512: at line 1
It seems always that way if an indexing failed, the index name can't be used any more, even if you do force to drop it.
Do anybody ever got and know the answer?
Thanks.

You need to delete the entry in dr$index table owned by ctxsys for the index you are trying to rebuild. Under certain circumstances this gets left behind and the force option also fails to remove it. Just delete it and you should be able to rebuild the index ok.

How can I configure ReFS to NOT fail read operations when a checksum error is detected (on non-Storage-Spaces volumes where data integrity streams are enabled)?

According to William Stanek, in his Windows Server 2012 R2 Inside Out: Configuration, Storage & Essentials book, this is apparently possible: (pg. 615 - here it is on Google Books: https://books.google.ca/books?id=0IyfBAAAQBAJ&pg=PT819&lpg=PT819&dq=read+operation )
Integrity can be enabled when the system is not running on Storage Spaces. When
integrity is enabled and ReFS detects a checksum mismatch, ReFS logs an event and
fails the read operation by default. If you don’t want the read operation to fail, you
can configure ReFS to continue with the read operation. A related event will be logged
regardless.
So then how do I configure it to do that???
(And just to make it super-clear, I'm NOT using Storage Spaces, so there is no redundancy via mirroring/parity, and I'm not expecting any file repair - just detection of corruption. It's just a basic volume formatted with ReFS and
with integrity streams enabled, via format E: /fs:ReFS /i:enabled
For those who want more details, here's the situation:
I try to perform a read operation on a file with corrupted data (purposely done for testing using a low-level disk editor), I get a the following error message:
And an event ID 133 from ReFSv1 gets logged in the System log:
Clicking "Try Again" just brings up the same message, and clicking "Skip" skips the operation entirely.
This is indeed the correct default behaviour.
What I want instead is for the read operation to be allowed to complete, with corrupt data and all, and ONLY for the event to be logged. And according to William Stanek, this is supposed to be configurable somewhere - and after hours of searching, I haven't
been able to find anything.

Hi Tommy,
>>How can I configure ReFS to NOT fail read operations when a checksum error is detected
We can use PowerShell command Set-FileIntegrity to configure this. The specific parameter for controlling this behavior is
-Enforce <Boolean>which indicates whether to enable blocking access to a file if integrity streams do not match the data.
Regarding this point, the following article can be referred to as reference.
Set-FileIntegrity

Still I get the above error messages, so I am at a loss what else to do...
A lot of thanks for your Support !

Hi Thorsten,
Please check the user used for registration of Diagnostic agent to Solution Manager has appropriate roles assigned (e.g. user SMD_ADMIN)
Also please update to latest patch of SAP Host agent and then try again.
Hope this helps

[Solved] Pacman preparation failed

I'm trying a new installation from a USB key and it fails on the Package Selection phase. The error message I get on tty7 is:
Execute(): worker_package_list exit state was 1
More info:
- arch is x86_64
- I'm installing from a USB stick on a laptop that has been running x32 arch for at least a year (it's a core2 cpu)
- I've checked and double-checked the md5sum of the iso and the image on the stick
- I'm using a core iso - no network access
- I select the local core repo when running aif
- I can see all the packages in /repo/core/x86_64/{core,any}
- I've read the aif bash scripts but so far I've been unable to see what the problem might be
I've read all I've found about the subject (there are many threads on this problem), but nothing that describes my exact situation; nothing has helped me. If somebody has any pointers, I'll be grateful!
-- buo
P.S: I've solved this problem; here's the solution in case anyone else encounters something similar. My drive was already partitioned and formatted, so I was telling aif to leave it alone. After I allowed it to reformat the root partition, the problem went away.
