... ... 1. Insert the CD containing the TREX installation files (Windows) or mount the CD (UNIX). 2. Package Location Specify the path to the CD containing the TREX installation files.
During the TREX installation, which you perform as the root user (UNIX) or as a user with administration rights (Windows), the operating system user <SAPSID>adm is created. For all operating systems, make sure that the user <SAPSID>adm has at least read-access to the TREX installation CD. Otherwise, a Python error message can occur during installation. If the <SAPSID>adm user does not have at least read-access for the CD containing the TREX installation files, you can copy the CD to your local hard-drive. To do this, specify in CopyPackageTo the path to the directory to which you want to copy the files on the TREX installation CD. 3. Choose Next. |
Typical Installation with Default Settings (Parameter Mode: Typical)
If you choose a typical TREX installation with default settings (parameter mode: typical), SAPinst runs mostly with automatic default settings. You only have to respond to a minimum number of prompts. However, you can still change any of the default settings on the Parameter Summary screen. During installation of a TREX global file system with a first TREX instance, you only have to provide the values for the following parameters:
● SAP System ID (SAPSID)
● Master Password (password for all users of this SAP system)
SAPinst sets all other parameter values automatically with the default configuration settings. You can change the default configuration settings before you start the installation process.
After SAPinst starts, the screen Welcome to SAP installation masterappears.

This screen and these entries are not required on UNIX 1. In SAP System User Domain ® Domain Model, enter the Windows domain in which the user accounts for the SAP system have been created: ○ Local Installation: You choose this setting if you are installing the TREX global file system with first TREX instance locally on a host. ○ Installation in Domain for Current User You choose this setting if you are installing the TREX global file system with first TREX instance in the Windows domain of the current user. ○ Installation in Different Domain You choose this setting if you are installing the TREX global file system with first TREX instance in a different Windows domain to that of the current user.
You must note that, in both cases involving installation in a Windows domain, you must have domain administrator rights in order to be able to create the required operating system users. 2. Choose Next. . |

TREX > Instance Choose a new TREX instance to install or an existing TREX instance to upgrade |
● TREX Installation Mode ® SAP System ID (SAPSID) The SAP system ID <SAPSID> that you created previously is displayed here. ● TREX Installation Mode ® Install a new TREX instance You cannot change this option because you are installing a new TREX instance and not updating an existing instance. ... 1. New TREX Instance ® Instance Number Enter an instance number for the TREX instance that you are installing. Note the following: ○ You can choose any number between 00 and 98. ○ The instance number must be unique on the host. If several instances of a piece of SAP software are running on the same host (TREX instances or instances of other SAP systems) they must have different instance numbers. If instances have already been installed, the system suggests the next available number. 2. Only Windows: Choose the drive on which the TREX software is to be installed. SAPinst checks whether the installation directory already exists. If not, it creates it. The directory is: ● On UNIX /usr/sap/<SAPSID>/trx<instance_number> ● On Windows <disk_drive>:\usr\sap\<SAPSID>\TRX<instance_number> The path to the directory is fixed and cannot be changed (apart from the Windows disk drive).
The directory should not be available before the installation unless you explicitly created it for space reasons previously (see Checking Disk Space). This allows you to ensure that the directory does not contain any data that does not belong to TREX, which would then also be deleted if TREX were uninstalled. |
TREX > Instance Details Enter values to configure settings for the following TREX installation components |
You can configure the following setting for the TREX installation: ... ● Install HTTP Server If the application communicates with TREX using an HTTP connection, select the field Install HTTP Server.
Only Windows: You have to ensure that the Internet Information Server (IIS) is installed and that the Default Web Site is running. To check this navigate to Control Panel ® Administrative Tools ® Computer Management ® Services and Application ® Internet Information Services (IIS) Manager. |
TREX > Proxy Settings Enter the proxy configuration settings |
If there is a proxy server between the TREX servers and the documents to be indexed, specify the proxy server and define exclusion rules if necessary.
You want to index the following: ■ Documents on internal servers that can be accessed without a proxy server ■ Web pages on external servers that can only be accessed using a proxy server In this case, specify the proxy server. Define exclusion rules for company-internal addresses, because the proxy server should not be used for those addresses, ● Proxy Server – host name and domain of the proxy server Example: proxy.mylocation.mycompany.com ● Proxy Server Port – port of the proxy server Example: 8080 ● Proxy User – user name needed to access the proxy server ● Proxy User Password – password defined for the user ● Proxy Exclusions – exclusion rules. These rules define when TREX is not to use the proxy server. Use a semicolon to separate multiple entries.
Examples of exclusion rules: ■ Do not use the proxy server to get URLs that end in mycompany.com: mycompany.com ■ Do not use the proxy server to get IP addresses that start with 10.: 10.
Do not use asterisks as placeholders. |
TREX > Languages for Document Analysis Enter the document analysis languages |
TREX supports the following languages for indexing and searching: English, German, French, Spanish, Portuguese, Dutch, Swedish, Finnish, Danish, Bokmal and Nynorsk (the two Norwegian languages), Italian, Japanese, Korean, Simplified Chinese, Traditional Chinese, Russian, Arabic, Catalan, Croatian, Serbian, Slovakian, Slovenian, and Czech If the application does not transmit the document language to TREX, TREX has to identify the language before indexing. You can select the languages that you want TREX to recognize.
Only select the languages that are relevant. This optimizes performance during the language recognition process, and therefore during the search and indexing process. The language recognition process gives better results if as few languages as possible are used.
However, TREX can also index documents whose language is not specified here. TREX then inserts the documents in question into the index for the default language (normally English). For example, if you select English and German and a document in Spanish is then indexed, the document is inserted into the English index. This affects the documents in question in the following manner: ■ A linguistic search is not possible. ■ TREX may extract keywords (document features) that are not characteristic of the document. |
