TREX 7.0

Hi,
i want to install TREX 7.0 search engine in my system. can any one help me in solving the following issues?
1.iam having the documents regarding installation, i need the installation materials. where to download?
2.what is meant by Installation with HTTP and RFC Connections? what is the difference in it?
3.what is meant by installing a global file system and a TREX instance or installing any one alone?
Thanks,
Kannan.

Hello Kannan,
1. you can download the installation material in the SAP Service Marketplace under Download --> SAP Installation & Upgrades --> Entry by Application group --> SAP NetWeaver --> SAP NETWEAVER --> SAP NETWEAVER 2004s --> Installations & Upgrades --> <OS system> --> <database type> --> Download Objects. You need the NW 2004s SR 2 Installation Master and NW 2004s SR2 Search/Class. (TREX)
2. The difference between http and RFC connection is the way you get the data for the index from your backend system. If you want to search in a web based backend system, http connection is the right way for connecting (for example SAP Enterprise Portal). If you use a SAP MyERP system based on ABAP (for example the E-Recruiting) you get a connection with the RFC (Remote Function Call).
3. With global file system SAP means the path of the profile of a SAP system. In a UNIX system it could be /usr/sap/<SAPSID>/profile (see all definitions under http://help.sap.com/saphelp_nw2004s/helpdata/en/40/937d7d66156365e10000000a114cbd/content.htm). The TREX instance is a SAP instance on a server which contents the TREX. Each instance has a number code with two figures (i.e. 00). For example a normal central portal installation has two instances: the SCS (SAP Central Services), the CI (Central Instance). If you i.e. install a portal and a TREX on one server you have three instances on this server.

How to configure one TREX host with multiple index servers ?

Hi All,
Does anyone know how to configure TREX on the one host,
with multiple index servers ?
Reason for this is to make better use of resources available on the host server(4 Gig, 4 Processor, Windows2003), to improve the search performance of
our KM content for portal users.
I am using TREX 7 and have not been able to do this,
despite reading the Single and Distributed install
documentation.
Any help would be appreciated.
Regards,
Andres

Hi Andres,
To make use of the RAM a Server provides you have to run two indexserver processes (each can then consume 2 GB);
Proceed like this:
1. Go to TREXdeamon.ini; check if section [indexserver2] is there (it is already provided, but not active in standard installation)
2. In TREXdeamon.ini go to
[daemon]
references sections below
programs=nameserver,preprocessor1,indexserver1,queueserver,alertserver
and add indexserver2 here. Restart TREX; second porcess is then started; can be checked in TREX monitor in Portal as well
3. To distribute existing indexes to the new process, start TREXadmintool and go to Index: Landscape
Go to the last two columns and move the indexes (move master here/secondary mouse click)
If you don't distribute the indexes the new index server process will be regarded when an new index is created.
Hope this helps!
cheers

Problem indexing with TREX

Hi guys,
We have some problems with our TREX system. This´s our environment:
- SAP Netweaver 7 - SP17 (SUN Solaris)
- SAP TREX 7 (Windows 2003 server)
- IIS 6 with SSO to File Server (SSO22Kerbmap configured)
The problem is that When indexing process is started, we detected that a lot of documents had preprocessing errors. We have in TREX log the following info for each file error:
2009-06-14 17:46:01.589 e preprocessor Preprocessor.cpp(00897) : HTTPHEAD failed for URL http://naspro01.xxxxxx.es:50000/irj/go/km/docs/departamentos/gc-idp/laboratorio/fichas%20de%20seguridad%20reactivos%20lab/merck_es_fichas%20de%20seguridad%20reactivos/1090/109033.pdf with Httpstatus 401

More information:
- index_service user have super administrator rol in our system.
- We have some errors in windows log about sso22kerbmap library. The text is 'Application failure: w3wp.exe, version:6.0.3790.3959, module: SSO22KerbMap.dll,version 1.1.0.8 ...'
Can somebody help us to solve this problem?
Best regards.

Hi Julio,
did you check the following SAP Note ?
SAP Note 735639 - SSO22KerbMap: Known issues
Did you also create an Active Directory User for the user index_service ?
This is described on page 7 in my white paper "[Integration of Windows File Servers into the SAP KM platform using SSO and the WebDAV repository manager|http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/e1f93f5c-0301-0010-5c83-9681791f78ec]".

How to configure trex name server

hi all
while creating index i am getting the error
Index could not be created; creating index failed: TREX Name Server (including back-up servers) is down or not accessable. (Errorcode 7217)
for the above error i need to configure the trex name server using TREX Configuration in the J2EE Engine in j2ee visual administrator .
can any one tell me the clear path that where to configure the above and where j2ee visual administrator installed how to configure the name server
awaiting for replies
regards
ganesh

Hi Ganesh,
In order to access the Visual Administrator, go to Start > Programs > SAP J2EE Engine > Visual Administrator. After you login, you will see 2 nodes i.e. Dispatcher and Server. Expand the Server node. Then go to "Services" and expand it. Then go all the way down to "TREX Service". Then on the right hand side, go to the property "nameserver.address" where you will key in "tcpip://<nameserver>:<port>". Then hit "Update" and click on the "Save" button. Then when you go to TRex Monitor, you should be able to see the Name Server running. Hope this helps.

Sri

How To Configure TREX Name Server&Port for UDDI Service Registry Settings

Hello Experts,
we are using CE 7.1 SP 4 and I would like to use the trex service in the Service Registry.
I use \NWA\Service Registry Configuration\Service Registry Settings\Keyword Search and want to test the TREX Communication using the Test Connection Button.
If I do so, I receive "Connection to TREX not successful".
When I press the Update TREX button I receive this exception:
com.sapportals.trex.TrexException: TREX Name Server (including back-up servers) is down or not accessable. (Errorcode 7217)
I tried to configure the trex.service with the two parameters: nameserver.address and nameserver.backupserverlist -> tcpip://myhostname.mydomain:30001 (Instance 00).
I am not sure if the port number is correct -> is there a way to lookup the correct port number?
Is there something else I should configure?
Thanks for help, best regards
Thomas

One TREX server for multiple Portals?

I have the same requirement as that contained in this thread:
TRex for Multiple Portals
I wonder if anyone can technically elaborate a bit what the procedure for this configuration.
I would have to install a TREX and create a TREX instance for each Portal that I want to give TREX service?
Each instance points to a different host?
My requirement is to use the same TREX to both DEV and QA Portal hosts.
Any suggestions would be appreciated. !!
regards,
Leandro.

Hi Leandro,
For your requirement this document describes the TREX installation -

TREX - Configuring Distributed Slave with Decentralized Data Storage

I am creating a distributed TREX environment with decentralized data storage with 3 hosts. The environment is running TREX 7.10 Rev 14 on Windows 2003 x64. These are the hosts:
Server 01p: 1st Master NameServer, Master Index Server, Master Queue Server
Server 02p: 2nd Master NameServer, Slave Index Server
Server 03p: Slave NameServer, Slave Index Server (GOAL; Not there yet)
The first and second hosts are properly set up, with the first host creating the index and replicating the snapshot to the slave index server for searching. The third host is added to the landscape. When I attempt to change the role of the third host to be a slave for the Master IS and run a check on the landscape, I receive the following errors:
check...
wsaphptd03p: file error on 'wsaphptd03p:e:\usr\sap\HPT\TRX00\_test_file_wsaphptd02p_: The system cannot find the file specified'
wsaphptd02p: file error on 'wsaphptd02p:e:\usr\sap\HPT\TRX00\_test_file_wsaphptd03p_: The system cannot find the file specified'
slaves: select 'Use Central Storage' for shared slaves on central storage or change base path to non shared location
The installs were all performed in the same with, with storage on the "E:" drive using a local install on the stand-alone installation as described in the TREX71InstallMultipleHosts and TREX71INstallSingleHosts guides provided.
Does anybody know what I should try to do to resolve this issue to add the third host to my TREX distributed landscape? There really weren't any documents that gave more information besides the install documents.
Thanks for any help.

A ticket was opened with SAP customer support. The response to that ticket is below:
Many thanks for the connection. We found out, that the error message is wrong. It can be ignored, if you press 'Shift' and button 'Deploy' (TREXAdmin tool -> Landscape Configuration). We will fix this error in the next Revision (Revision 25) for TREX 7.1.

Hi Niloufer123
Have you regenerated your Repository after making changes?
If not, go to SA38 and run program CRM_ERMS_REGEN_RULES for ERMS context for your Policy (check box checkboxes).
Now re-run your scenario. Hopefully this has helped.

TREX Installation, Error in phase - Install TREX web resources and finalize

Hello,
Platforms:
SO - Win 2008 (R2) X64
During the last phase "Install TREX web resources and finalize instance" in installation process of TREX 7.1, it show me a weird error...
It seems that was some problem during the creation of sap start service of this new instance... but that is weird because I checked at services.msc and that service SAPTSM_02 and nothing seems wrong with it, it seems that was well created and it is in Started mode!... I checked firewall settings (all of them are in OFF status), I also checked CUA settings (is stopped)...
I searched for this error and I found the following SDN forum:
SAPNW EHP1 SR1
I already press the retry button but it always show me the same error.
During this phase the SAPInst window show some information and in there I see this two:
creating sap start service of instance TSM/TRX02...
service not correcttly installed.
It is very weird thing!
I will post some log files such as sapstartsrv.exe and sapinst.log.

Can you help me please, how can I solve this?
Kind regards,
JDimas

Hello Arjun Venkateswarlu,
1).Is your Windows Firwall is enabled ? Disable the windows Firewall and also restart SAPinst
- As I said the windows firewall is disable (OFF)
2). Make sure that <sid>adm belongs to the local admins or Better provide the domain admin rights to the id which you are using for installation if it is domain installation.
- All the created users during this installation belongs to local admins. This isn´t a domain installation!
3). Try Restarting the installation by stopping and starting Windows and restart SAPINST and coninue Old Installation again.
- I already did that... but it continues to show me the same error!
Any other tip?
Kind regards,
JDimas

Problem with TREX 7.0 : HTTP Server is not working

Hi all,
I have installed TREX 7.0 recently(Windows XP Pro, with IIS 5.1). I'm having portal installed in the same system(NW04s). After this installation I found that status of httpserver is red, rest all servers are having green status. I checked it in IIS, there also its indicating same(SAP_TREX_02 (Stopped)). I tried to connect http://<host-name>:30205/TREXHttpServer/TrexIsapiExt.dll, but its giving error as,
Error occurred when connecting to the server!
Description: Can't connect to the server.

I'm not able to get why http server is not able to get up. Please help me to resolve this problem. Waiting for some quick response.
Thanks in advance,
Ganpati Jha

Hi,
do you configured TREX server in EP ?
You must configure the TREX name server in Visual Admin, to point to TREX.
Your error message say "Server: <host-ip>:30205", what is <host-ip>? I think that is the problem, it must be your server name.
Check this:
http://help.sap.com/saphelp_nw04s/helpdata/en/c7/e0d13f7fb44c21e10000000a1550b0/frameset.htm
