The memory management system is automatically activated and configured using your entries during the installation or the upgrade.

Prerequisites

Before you install the R/3 System or upgrade to a 4.x version, ensure that the host system(s) on which the R/3 application server is/are set up, fulfill all the requirements particularly regarding main memory and swap space.

For more information, see:

Operating System and Hardware Prerequisites.

Also refer to the installation checklist and the installation documentation OS Dependencies.

Procedure

Configuring the Memory Management System

The memory management system is preconfigured in the course of the installation/upgrade procedure. The installation/upgrade program requires information about the host system and sets the memory management parameters for each procedure either to the default values or to the values corresponding to the input. This preconfiguration is valid for the host system on which you perform the installation, and for the server you set up during the installation.

Checking and Adjusting the Configuration

Check the preconfigured memory management system and your host system using the following sample configuration and guidelines.

Requirements for the Host:

Checking the Hardware and Operating System of the Host System

Sample Configurations:

Application Server with Up to 15 Users

Application Server with Up to 50 Users

Application Server with Over 50 Users

Configuration Help for Various Platforms:

Configuration for UNIX / Windows NT

AS/400 Configuration

Memory Management under Windows NT

Configuration for AIX

In the following cases, it could be necessary to use a temporary license to bridge the time until the SAP license has arrived by fax:

  • If the hardware configuration of the host on which the message server is running changes, the customer key of the host can also change.
  • If the message server is moved to another host.
  • If the license has expired. The expiry date can be extended by 3 weeks with the temporary license.

Procedure

  1. Log on to the host on which the central SAP instance is running as user
    2.  adm (UNIX and NT) or OFR (AS/400) at operating system level.
  2. Enter saplicense -temp (AS/400: saplicense '-temp').

Enter the SAP System ID when it is requested.

The following message shows that the program has terminated successfully:

saplicense: Temporary license successfully installed

Rejection of a Temporary License

SAPLICENSE rejects installation of a temporary license in certain cases:

  • A temporary license can only be installed if a valid license existed and has been used recently (within the last 3 weeks).

The following message tells you that a temporary license cannot be granted because the date of the last successful license check was more than 3 weeks ago:

saplicense: Temporary license NOT installed, *** Old license older than 3 weeks
  • If the R/3 System is set up from a copy of an existing R/3 System, it is not possible to install a temporary license for the first time.

Apply for a license before you want to work with an R/3 System that has been copied.

SAP Installing an SAP License

Prerequisites

The 24-position license key, which you receive from SAP by fax.

Procedure

  1. Log on to the host on which the central SAP instance is running at operating system level as user
    2. adm (UNIX and NT) or OFR (AS/400).
  2. Call
    3. saplicense -install [ifile=] (AS/400: saplicense '-install [ifile=]'). If you are using an R/3 license key file, enter it as the . This file is created in OSS when your license key is assigned. If you are unable to download the installation file to your system, you can copy the contents of the file with cut and paste.


Example of an R/3 license key file:

#
SAPSYSTEM=C11
CUSTOMER-KEY=A0123456789
INSTNO=0123456789
EXPIRATION=99991231
LKEY=012345678901234567891234
#

If you are entering the data manually (that is, you are leaving out the optional parameter), make sure that you enter the key correctly, for example, that you distinguish between the number 0 and the uppercase letter O.

Example for entering the license data manually

Specify your sap system name:
SAP SYSTEM NAME = PRD

Specify your customer key:
CUSTOMER KEY = D1889390344

Specify your installation number:
INSTALLATION NO = 0005500021

Specify your expiration date:
EXPIRATION_DATE [YYYYMMDD] = 99991231

Specify your license key:
LICENSE_KEY 1...5....0....5....0...4
LICENSE_KEY = 9KJDYITLVLPRZS9WXVS8SNTN

saplicense: License successfully installed

The license is now installed and activated.
  1. Check whether you can log on to the R/3 System.

After logging on, choose System ® Status.

Check whether the following SAP system data agrees with the data just entered:
    • Installation number
    • License expiration

If you can log on and the data is correct, the license was correctly installed.

Troubleshooting

  • If you get the following message when installing the license:

saplicense: License not installed, *** Wrong license data specified

you probably mistyped one of the values. Please make sure that you use the correct uppercase/lowercase in the entries.

Also note that the Backspace (delete character) key is not set correctly on some terminals. You should therefore avoid using this key.
  • It is not necessary to start/stop the R/3 System in order to install the license. The installed license becomes active immediately.
  • If you experience any problems installing the license key, enter a problem message in OSS specifying component XX-SER-SWFL-LIC.
