1. Introduction

Faculty of Economics of University G.D'Annunzio this year has joined SAP University Alliance1, with the

purpose of giving students skills and knowledge about of the World's Largest Business Software Company.

The SAP University Alliances program is a global endeavour that provides university faculty members withthe tools and resources necessary to teach students how technology can enable integrated business

processes and strategic thinking – and gives students the skills to add immediate value to the marketplace.SAP University Alliances member schools gain access to the SAP Business Suite family of solutions,including SAP ERP. This comprehensive business software suite supports business, engineering, andinformation technology programs, enabling students to put classroom theory into practice throughdemonstrations, exercises and problem-solving, case studies, and research programs.The courses activated this year are "Laboratorio di Sistemi ERP" and "Sistemi Integrati di Controllo".

Components choice

Operating system: We have chosen CentOS operating system because it is build as a "clone" of the mostfamous Red Hat Enterprise Linux. The latter one, is one of the official Linux distributions supported by SAPAG.

3

CentOS is designed for people who need an enterprise class Operating System without the cost or supportof Red Hat Enterprise Linux vendor.

4

DBMS: MaxDB is a heavy-duty, SAP-certified open source database for OLTP and OLAP usage whichoffers high reliability, availability, scalability and a very comprehensive feature set. It is targeted for largemySAP Business Suite environments and other applications that require maximum enterprise-level databasefunctionality and complements the MySQL database server.

5

ERP System: SAP IDES – This SAP Product is used for demos, online/classroom training. In fact the"Internet Demonstration and Evaluation System" in the R/3 System, represents a model company, thatconsists of an international group with subsidiaries in several countries. IDES contains application data forvarious business scenarios that can be run in the SAP System. The business processes in the IDES system

are designed to reflect real-life business requirements, and have access to many realistic characteristics.IDES uses easy-to-follow business scenarios to show you the comprehensive functions of the R/3 System.

2. Prerequisites

If you want to install a central system (ECC), that is, all instances reside on one host, the host must meet thefollowing requirements:Host with at least 1 GB RAM and 180 GB Hard Disk spaceThe CentOS Operating system installedThe SAP ERP 2005 SR2 IDES installation mediaSAP Solution Manager Key for SAP softwareFor the last point, you have to install SAP Solution Manager, before start with IDES installation. Without thekey generated by SAP Solution Manager, you can't proceed with the installation/upgrade of your SAP IDESsystem.

- Hardware

Our host where we have performed SAP ERP 2005 SR2 IDES installation is:IBM eServer xSeries x346, Dual-Core Intel Xeon Processor 3.40GHz , RAM 4GB, 2 Hard Disk 300 GB(RAID-1). This server is an officially SAP supported platform.However, SAP currently supports hardware from Bull, Dell, Fujitsu-Siemens, HP, IBM, SGI, SunMicrosystems and Unisys, which includes both 32Bit and 64Bit architecture.Before start, is recommended to check if your server is a SAP supported platform.7

3. CentOS installation

- Download ISO.

To install the system you will need to download the CentOS 4.4 DVD ISO image from a mirror near you.Or use bit torrent to download the .torrent files provided.

- Raid.

Note: we have chosen to use Linux's software RAID because the SCSI hardware controller on-board is anAdaptec "SCSI Card 29320ALP", also known by IBM as "ServeRAID-7e", which offers a "fake" RAIDcontroller through a closed source, minimally tested driver from Adaptec.

8

Moreover Software RAID implements the various RAID levels in the kernel disk (block device) code. It offersthe cheapest possible solution, as expensive disk controller cards or hot-swap chassis are not required. Withtoday's faster CPUs, Software RAID outperforms Hardware RAID.

- CentOS installation: main steps.

Boot from your first CentOS 4.4 CD, and press enter at first screen that appears (See Figure 1).

Figure 1

The first step is test the installation media, but it can take a long time to so we can skip this test.After the welcome screen of the CentOS installer, we have to choose the language and keyboard layout.Next, we choose the installation type a Desktop installation is perfect for our purposes.The partitioning tool used by the installation program is Disk Druid.

In our case, on University, we're installing CentOS 4.4 on a fresh system, so we answer Yes to the question"Would you like to initialise this drive, erasing ALL DATA?"

On the next screen we Select Remove all partitions on this system.

On the partitioning, it's strongly recommended to use RAID. Redundant Array of Independent Drives (or Disks) is an umbrella term for data storage schemes that divide and/or replicate data among multiple harddrives. They offer, depending on the scheme, increased data reliability and/or I/O performance.On the partitioning, we could choose to do a small boot partition and a large / (root) partition, but we stronglyrecommend using RAID.

For more information on how create partitions on your CentOS system visit: http://www.redhat.com/docs/manuals/enterpriseWhen you've finished, the installer presents you an overview of the new partitions created. If you aresatisfied Click on Next to continue

http://www.redhat.com/docs/manuals/enterprise

Figure 2

Now the boot loader GRUB will be installed. You can leave the default settings unchanged and click on Next.To improve security of the system, you can choose to Use a boot loader password. In the "Firewall" dialog choose "No firewall". If you want to configure a firewall on the system, you need toconfigure it manually after installing the system. In that case ensure that the SAP application server ports areaccessible from other machines. The ports used by the SAP application server can be found in /etc/servicesafter it is installed.

Click on to the network settings. The default setting here is to configure the network interfaces with DHCP,

but we are installing a server, so static IP addresses are not a bad idea. Click on the Edit button at the topright. In the window that pops up uncheck Configure using DHCP and give your network card a static IPaddress. After that set the hostname manually, enter a gateway and up to three DNS servers.

Pay attention, this setting is very important after for the SAP installer. The "hostname" should be just ahostname and not the full qualified hostname."hostname" and "hostname -s" commands must return the hostname without domain. "hostname -f"

must return the fully qualified hostname and domain.To do that, check that hostname is set to the short name without domain in /etc/sysconfig/network and set up

/etc/hosts that it is configured like this:

127.0.0.1 localhost.localdomain localhost

192.168.0.1 server1.example.com server1

It is important that the fully qualified domain name is in the second column, followed by any alias names andthat the hostname of the machine is not associated with the IP address 127.0.0.1.Afterwards run hostname <shorthostname> to set the hostname without rebooting.We have disabled SELinux security system, to avoid possible problems with SAP installer. After, Select thedefault language, time zone, and set root password.

Now you have to select the package groups we want to install. Select Editors, Text Based Internet, ServerConfiguration Tools, Development Tools, Administration Tools and System Tools. Uncheck Web Server, MailServer, DNS Name Server, FTP Server, MySQL Database (see Figure 3). They are not useful for ourpurposes.

Figure 3

Press next to start the installation. This will take a few minutes. Finally, when it is completed, you can removeinstallation CD from the server and reboot it. 4. Post Installation Activities

Before starting IDES installation, we've to perform some "tuning" on our new CentOS System.

- Vino Setup

To access the X-Windows system from remote you can setup VINO. Vino is a tool for remote administrationreadily built into the GNOME Desktop Environment.You can configure VINO from Applications -> Preferences -> Remote DesktopCheck "Allow other users to view your desktop" to automatically start VINO at GNOME startup, "Allow otherusers to control desktop" and "Require the user to enter this password:" setting a secure password (SeeFigure 4).Make sure you have the VNC port (TCP 5900) open in your firewall configuration.

- SAP locales.

Donwload from service.sap.com saplocales for your server architecture. Install it on a terminal prompt,typing:

rpm -Uvh saplocales-2.3.4-3.x86_64.rpm

Figure 4

- Java Runtime Environment

Java Environment: Today there is not a SUN Java Environment for GNU/Linux certified by SAP for 64 bitArchitecture.The only solution is to use Developer Kit for Linux, Java 2 Technology Edition build by IBM.

Install it on a terminal prompt, typing:

rpm -Uvh IBMJava2-AMD64-142-SDK-1.4.2-6.0.x86_64.rpm

At the end set environment variables, in our case:

export JAVA_HOME=/opt/IBMJava2-amd64-142/jre/export PATH=$JAVA_HOME/bin:$PATH

Test that everythings is ok with java –version. The output should be like this:

java version "1.4.2"

Java(TM) 2 Runtime Environment, Standard Edition (build 2.2)

- OS-Release.

As described from SAP note 171356, CentOS GNU/Linux is not an official supported platform. For thisreason, if you want to avoid the warning of the prerequisite-checker tool you can modify /etc/redhat-release

file (See Figure 5). Substitute the entry that you find with "Red Hat Enterprise Linux AS release 4 (NahantUpdate 4)

Figure 5

- Set Kernel Parameters.

You have to set some kernel parameters10

. This is done in /etc/sysctl.conf:

kernel.shmmax=23136829430

kernel.shmall=5242880 (adapt according to SAP note 941735)

kernel.msgmni=1024

kernel.sem=1250 256000 100 1024

10 SAP Note No. 171356

vm.max_map_count=300000

Edit this file with you favorite editor, and then activate the changes, running sysctl -p

- Shared Libraries.

To avoid any problems with shared libraries, before start type the command ldd ./sapinst, to check what are

the libraries that are needed from sap installer (See Figure 6).

Figure 6

5. Preparing SAP ERP 2005 IDES Installation

- Copy Installation CDs/DVDs to Hard disk.

To make installation easy you should copy all needed disks to your Hard disk. You will need:SAP ERP 2005 SR1 Installation Master DVDSAP Netweaver 2004S SR1 Kernel 7.00SAP ERP 2005 SR1 IDES DB-Export Part 1, 2, 3, 4, 5MaxDB RDBMS Linux

For SAP GUI installation (front-end to access to your IDES system), you'll need also SAP NetweaverPresentation dvd, where there are sap gui for all operating systems.We’ve created the directory /home/sap with a sub-directory for every Disk:

mkdir /home/sap

cd /home/sap/

mkdir kernel

mkdir dbex1





© 2007 SAP AG

Enter the SAP System ID, SAP System Mount Directory (you can leave default value /sapmnt), and checkUnicode System (recommended by SAP).Type the Master Password for your system.Enter the Database Identification Parameters: DBSID and the host where is located your DB. (by default isthe same host where you're performing SAP installation).Enter Database Parameters like: Volume medium type, mirror log volumes, CPU used, I/O buffer cache,

Number of sessions.Enter the Central Instance parameters: Central Instance Number, Central Messaging Service Port andInternal central Messaging Service Port (you can leave blank these last two parameters).At the end you are prompted to enter the "SAP Solution Manager Key".

This key is needed to proceed with the installation/upgrade. Without this key, the installation processcannot continue.

11

So, to continue with installation process, before you need to install SAP Solution Manager. Alternatively youcan generate it using SMSY transaction in another SAP system running.At the end we receive a Parameter Summary, where we can decide to revise some values before startinstallation.

11 See SAP note 805390.

Now you can start SAP ERP IDES installation!

Figure 7

- Note.

The IDES installation with MAXDB on Unix, is affected from a "bug".12

The MaxDB parameter SHAREDSQL must have the value NO during the ERP ABAP installation otherwiseR3load might get stuck - that is, R3load might stop processing but without issuing an error message.

So, after you have entered all parameters in the SAPinst dialogs and before you start the installation with'Start', open the file <dbsid>_sapdb_db_parameter.txt and enter the following new line: SHAREDSQL NO

After the installation has completed and after you have updated the database software to the most recentversion. Moreover, check SAP Note 814704 to see whether you need to reset the SHAREDSQL parameterto YES.

Another workaround (that we've used) is to use only one single R3load process, because in this case thesituation can be avoided. (See Figure 8)So before start installation in the Parameter summary screen, that you can see in the screenshot below,decrease the value of Parallel jobs from "3" to "1".

7. Post Installation activities.

- Install SAP GUI for JAVA.

When the installation is completed. You can log on on your new SAP IDES System via SAP GUI.In our case, we've installed a sap gui for java on GNU /Linux Ubuntu Edgy machine.First of all, download the SAP GUI for Java installer.

13The latest version at the time of writing is 700r4

Type on a terminal prompt:

wget ftp://ftp.sap.com/pub/sapgui/java/700r4/PlatinGUI-Linux-700r4.jar

Before installing sapgui for java, we have to install java runtime environment (jre).It is now very simple,because Ubuntu has Sun Java 5 runtime environment packaged in the multiverse.

14

13 For the supported platforms of JAVA GUI refer to note 954572.14 This topic is covered in more detail at: https://help.ubuntu.com/community/Java

System --> Administration --> Software Sources (or Software Properties)Enable the multiverse repositorySystem --> Administration --> Synaptic Package ManagerSearch for sun-java5-jre and mark it for installationHit apply to download and install the JRE.Now we can install SAP GUI, by running the following command on a terminal prompt:

java -jar PlatinGUI-Linux-700r1.jar

Start sap gui by running guistart with the necessary parameters. For example /H/ is used to prefix thehostname of the application server you wish to connect to and /S/ is used to prefix the socket you wish toconnect to. The following example assumes a hostname of "foo" and a system number of "00".

~/SAPClients/SAPGUI7.00rev1/bin/guistart /H/foo/S/3200

Otherwise give on terminal prompt

~/SAPClients/SAPGUI6.40rev6/bin/guilogon

A SAP GUI will appear, click on the button "new" and the in the tab advanced Type a description and check"use expert configuration" .In the text-box insert a string like this conn=/H/foo/S/3200.Press the button save, and you will appear a new connection string on your sapgui. (See Figure 9).

- Log on to IDES.

Select the entry, that you have created and press connect. In the clients 000/001 you can logon with DDICand SAP* with the password you have defined at the beginning of the installation as 'Master-Password', inthe clients 8xx with the password 19920706 / 06071992 and in all clients with IDADMIN / ides.

15

Create a user within client 000 (for some tasks required to be done within client 000, but with a user differentfrom users sap* and ddic). Profiles required are sap_new and sap_all. For additional safety the passwords ofdefault users within all clients should be changed (this includes users sap* and ddic).

- Change Default client.

MYSAP ERP IDES is installed with 7 clients: '000','066', '100', '800', '810', '811', '812'. You can check withtransaction SCC4. (See also Figure 10)It is not recommended log on and use client 000. Moreover this client doesn't contain any business data. Alldata of the IDES model company can be found in client 800

Figure 10

So if you want to log on with 800 client by default instead of 000 we need to set a parameter in default

profile.Go to RZ10 select default profile->extended maintenance->change

LOGIN\SYSTEM_CLIENT=800 (replace 000 with 800) and save the profile.It will ask for MMC restart.

- License key

The license key of your new installation is valid only for a test period.You can check the validity of your license by logging onto the SAP System and reading the copyright or by

15 See note 1013391.





© 2007 SAP AG

choosing System -> Status -> SAP system data. To operate in your new SAP system on a permanent basis you need to install a permanent license.To request a license key on-line, go http://service.sap.com/licensekeys.

16

Figure 11

As shown in figure 11, on the web page, select Request License Key, select an installation (ERP 2005 in ourcase), select New System to request a license key for a newly

installed system and add the required system and hardware data.

Finally Submit to send the license key request to SAP. You will receive soon an email with attached theLicense key for your new SAP system.When you receive mail from SAP License audit, in your SAP system launch SLICENSE transaction

Choose New Licenses to enter the new license view.SAP License Administration -> Digitally-Signed License Keys, choose Install.Load the local file from the file system in the dialog box appears, enter the license key file and confirm.A message appears to confirm success.

- SCCR: SAP Software Change Registration

Probably in your SAP IDES system, you may need to create zreport or modify some repository objects.If you access to ABAP Editor (t-code SE38) to create a zreport for example, you will receive a pop-up, wherethe system advise that your user is not a developer user (See Figure 12). So you have to register to OnlineService System (OSS).

Figura 12

Go to http://service.sap.com/sscr, click "Keys & Request" and the "SSCR Keys".Click on the button "Register developer", enter an ID (i.e developer01), and select the installation and thepress Register.You will receive a Registration key, to paste the first time when you try to modify a repository object of yoursystem.

8. Starting and Stopping SAP ERP 2005 IDES

For some reason you need to stop and then restart SAP IDES. Before, you have signed on to the SAPsystem hosts as user <sapsid>adm.If you have a central system – that is, central instance, central services instance and database instance onthe same host – enter the following on the central system host in a prompt terminal:

startsap

This checks if the database is already running. If not, it starts the database before starting the centralservices instance and the central instance.You can start the database and SAP system separately by entering the following commands:

startsap DB <instanceID>

startsap R3 <instanceID of central services instance>

startsap R3 <instanceID of central instance>

To stop SAP IDES, if you have a central system, enter the following on the central system host:

stopsap

This stops the central instance, the central services instance and then the database.
