Welcome to SAP Installation Master

...

       1.      In the folder hierarchy, choose SAP NetWeaver 7.0 Support Release 2 ®Standalone Engines ® Search and Classification (TREX) ® TREX Instance.

       2.      Choose Next.

The DVD/CD Browser > Software Package Request screen appears.

DVD/CD Browser > Software Package Request

...

...

       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.

TREX > Installation

Confirm the installation of TREX Search and Classification

Choose Next.

SAP System > General Parameters

...

...

       1.      In SAP System Parameters ® Profile Directory, enter the path to the directory in which the SAP system profiles are stored:

Windows: \\<SAPGLOBALHOST>\sapmnt\<SAPSID>\SYS\profile

UNIX: /<SAP System Mount Directory>/<SAPSID>/profile

In the default scenario, the SAP system profiles are located on the host on which the TREX global file system with first TREX instance has been installed. You can choose Browse to search for the directory.

The global file system must be highly available. All instances of a TREX system must have permanent access to it. You guarantee this by inserting the profile directory as a network drive (Windows) or by mounting it (mount/UNIX).

       2.      Choose Next.

SAP System > Master Passwords

...

...

       1.      Password for all users of this SAP system

       2.      Confirm

Specifies one password for both for the SAP system administrator and SAP system service user.

The password is to be used for all accounts that SAPinst creates and for the secure store key phrase. The password has to be 8-14 characters long. Depending on your installation scenario, there might be more restrictions.

You can choose a different value for each password by choosing to edit the relevant parameter section on the Check Parameter screen. If you set already one password to a different value and change the Master Password in this dialog afterwards, the individually set passwords are NOT overwritten with the new master password.

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> is displayed here. The system ID was previously defined during one of the following steps:

○       Configuration of a TREX system landscape with preceding installation of a central TREX instance and the associated global file system. The system ID defined during installation of the central TREX instance is then valid for all TREX dialog instances that are added to the TREX system landscape.

○       Installation of a global file system only on a separate host

●      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 doesn't 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 make the following settings for the TREX installation:

...

●      Install HTTP Server

If the application uses a HTTP connection to communicate with TREX, select the Install HTTP Server field.

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. Since the proxy server should not be used for internal addresses, define exclusion rules for internal 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 the proxy server is not to be used. Separate multiple entries using a semicolon.

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.

Check Parameters

SAPinst displays all settings before you start the installation procedure: the settings chosen by you and the default configuration settings automatically filled in by SAPinst.

●      You can check the settings and choose Revise  to change any of them if necessary. In this case SAPinst will go back to the installation window where you can fill in the specific settings you intend to change.

●      To start the installation with the selected parameters,
choose Start.
