You can initially install TREX in the following way:

      Installing TREX by CD

You install TREX using the CD containing the TREX installation files that will be part of the SAP NetWeaver delivery.

      Installing TREX by software package

You install TREX using the TREX software package that can be downloaded from SAP Service Marketplace (see Downloading TREX).

Hinweis

Both installation procedures only differ in the way you navigate through the initial screens. The required input is the same for both installations.

The tables below show the names of the screens that are displayed during the installation of TREX and the entries that you need to make.

Hinweis

For more information about the directories that the installation creates, see TREX Global File System and TREX Instances.

Diese Grafik wird im zugehörigen Text erklärt

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.

Choose Next to continue.

 

Installing TREX by TREX Software Package

You install TREX using the TREX software package that can be downloaded from SAP Service Marketplace (see Downloading TREX). After SAPinst starts, the screen Welcome to SAP Installation Master appears.

Screen

Input

TREX Installation

Choose Next.

 

Input Screens for Installing TREX

The installation procedures for installing TREX by CD and by software package only differ in the way you navigate through the initial screens. The required input is the same for both installations.

SAP System > General Parameters

...

       1.      SAP System ID (SAPSID)

Enter an SAP system ID <SID>.

The SAP system ID consists of three characters and must begin with a capital letter, after that it can contain numbers.

Achtung

When you choose a system ID <SAPSID>  for your TREX landscape check which system IDs are already in use by other SAP applications on the same host where TREX is to be installed. Do not use a system ID <SAPSID> that is already assigned to another SAP system landscape for your TREX installation and landscape. Otherwise an error message appears.

       2.      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.

       3.      Destination Drive (Windows Only)

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).

Achtung

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.

       4.      Choose Next.

SAP System > Windows Domain and Master Password

...

       1.      SAP System User Domain (Windows Only)

Achtung

The entries for an SAP system user domain are not required on UNIX.

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 TREX locally on a host.

       Use Domain for Current User

You choose this setting if you are installing TREX in the Windows domain of the current user.

       Use Different Domain

You choose this setting if you are installing TREX in a different Windows domain to that of the current user.

Achtung

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.      Master Password

...

                            a.      Password for all users of this SAP system

                            b.      Confirm

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

The password is used for all accounts, that SAPinst creates and for the secure store key phrase. The password must 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 summary screen. If you already set one password to a different value and the change the master password in this dialog, the individually set passwords are NOT overwritten with the new master password.

       2.      Choose Next.

Parameter Summary

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

...

       1.      You can check the settings and choose Revise to change any of them if necessary.

In this case, SAPinst goes back to the installation screen where you can enter the specific settings you want to change.

       2.      To start the installation with the selected parameters,
choose Next.
