9 The PREPARE Process The PREPARE is the first major part of the upgrade. Data and programs are copied to the upgrade directory, tools are imported into the database, and the shadow instance is installed. Add-ons, support packages, and languages are integrated into the upgrade. After the initial configuration of the upgrade, PREPARE verifies that the source system meets the requirements of the upgrade process and of the target release. This produces an action list that must be taken care of before the actual upgrade can start. Note: PREPARE is executed with the system running. End users are not affected. 9.1 The Upgrade Assistant Description The application that manages the upgrade process is the Upgrade Assistant ( UA ). The UA is delivered on the Upgrade Master CD, and it is installed into the ua subdirectory of the upgrade directory. The UA has two components: the server and the client. The UA Server runs on the upgrade host. It drives and controls the technical upgrade program ( R3up ) and interacts with the UA Clients The UA Client is the graphical user interface ( GUI ) used to control and monitor the upgrade. In subsequent chapters, we refer to it as the UA GUI. The GUI can run on the same host as the server, but also on a different host ( typically an administrator s PC ). The UA GUI communicates with the UA Server via TCP/ IP ports. It can run as a standalone application or as an applet started from a Web browser. You ll find screenshots of the Upgrade Assistant and the Upgrade Monitor in Section 5.4. Tip: The UA for mysap ERP 2004 has few differences with that of previous releases. If you already used the UA for past upgrades, then you will be immediately familiar with it. Administrator and Observer Modes Any number of UA GUI sessions can connect to the UA Server simultaneously. Only one session, however, can be in control of the upgrade at any one time. This session is the upgrade administrator. Whenever the UA Server needs user input, a data entry window will open automatically in the administrator session. All other UA GUI sessions are observer s. They show the current phase of the upgrade and will also show ( but in read-only ) the user interaction that takes place with the administrator session. When you log on to the UA GUI, you specify the role you want your session to take on by entering a password. The UA has a separate password for each role. The initial passwords ( which can be changed in the UA GUI ) are: Administrator: admin Observer: observer Provided he or she knows the administrator password, it is possible for an observer to take over the administrator role. The current administrator is then automatically demoted to observer. This happens without interaction; that is, the UA GUI will not ask the current administrator to allow or acknowledge the take-over and his or her own demotion. This may seem a bit drastic, but it is actually quite smart. Imagine that during a long-running upgrade the workstation currently running the UA GUI in administrator mode at some point becomes out of reach ( you have gone home and want to continue the upgrade from your home PC via a VPN connection ). In such a www.sap-press.com 81

9 The PREPARE Process case, it makes perfect sense not to interact with the current administrator when switching roles. Scroll Mode It is possible to run the upgrade, and to interact with it, from a plain command window, such as a Telnet session or a DOS shell. In this case, you do not use the UA GUI. This method is called scroll mode, and is similar to the old method used up to SAP release 3.x, when R3up was a terminal-based process. There is really no reason to run in scroll mode, because the disadvantages are significant. Apart from the fact that user interaction is much less user-friendly, the upgrade process is also far more vulnerable because it depends on the network connection of the terminal session. If this connection fails or you accidentally close the session window, the upgrade stops and specific recovery actions are necessary before you can safely restart it 1. 9.3 R3up and Correction Transports Before you continue with the technical upgrade, now is the time to replace the R3up from the upgrade kit with the fixed version ( see Section 8.5, under the heading R3up Fix and Correction Transports ) and also to copy the SAR archive with the correction transports ( see same section ) to its proper location. Replace R3up Caution: You should only replace R3up before the first run of PREPARE. Never replace R3up during the upgrade unless instructed to do so by SAP! 1. Go to directory <PUTDIR>/bin. 2. Rename R3up, for example to R3up.orig. 3. Copy the fixed R3up you downloaded earlier to <PUTDIR>/bin. Make sure that ownership and file access are the same as for the original R3up file. 9.2 The Initial Extraction Script The very first step in the technical upgrade process is to run a script that extracts a minimum set of files ( including the UA ) to the upgrade directory and also performs some basic checks of the server. This script is located on the Upgrade Master CD and is somewhat confusingly called PREPARE ( it is not the same as the PREPARE process, which is the first major step of the upgrade and is not run via this script ). As a starting condition the upgrade directory must be empty. 1. In a command window ( Telnet session, DOS shell ) log on as the SAP administrator account ( <sid>adm ). 2. Locate the PREPARE script for your O/S platform on the Upgrade Master CD. 3. Execute the script. Example ( user input is shown in bold ): The mounted CD Set is for database <DBMS> only. Does your system run on DB <DBMS>? YES Select operation mode EXIT 1 For details, see section Restarting the Upgrade in Scroll Mode in the SAP Upgrade Guide. Correction Transports Unpack the ECC_500*.SAR archive that contains the correction transports to the top level of the upgrade directory: (logged on as <sid>adm) cd <PUTDIR> SAPCAR xvf <path>/ecc_500*.sar Two files will be extracted. One has extension.info, the other is again an SAR archive named FIX_ECC500SR1. SAR. Do not unpack this file yourself. PREPARE will do this for you. 9.4 Copy Phase List Files to PC ( Optional ) The list of upgrade phases is no longer in the upgrade manual; instead it comes as a set of HTML files, which you can transfer to the PC. Copy the following files to your PC: <PUTDIR>/htdoc/phaselist.htm <PUTDIR>/htdoc/phase_toc.htm PHASE_TOC.HTM lists all upgrade phases as hyperlinks to the detailed phase list. PHASELIST.HTM contains the actual phase list for PREPARE and R3up, divided into major 82 Galileo Press 2006. All rights reserved.

9.7 Start UA GUI and Log In sections. This corresponds to the phase list that used to be part of the upgrade manual in earlier releases. PROP((os400.file.io.mode TEXT)(os400.verify. checks.disable 3)) 9.5 Install UA GUI on Workstation ( Optional ) This step is only necessary if you want to run the UA GUI as a standalone application from your workstation. If you choose to run the UA GUI as an applet from a browser, then you may skip this step. 1. Create a folder on the PC to hold the UA GUI files ( e. g. C:\UAGUI ). 2. Transfer ( in binary mode ) the following file from the server to the folder you have just created: <PUTDIR>/ua/uagui.jar 3. Open a DOS shell and try starting the UA GUI: cd C:\UAGUIjava cp uagui.jar UaGui ( with standard Java VM : jview /cp uagui.jar UaGui ) The UA GUI logon screen must appear. Exit for now, because you haven t got the server running yet. 9.6 Start the UA Server Follow these instructions to start the Upgrade Assistant server. UNIX ( see note below ): (logged on as <sid>adm) java cp <PUTDIR>/ua/ua.jar UaServer Note for UNIX: It is not a good idea to run the UA Server in a dedicated terminal window, because the server then would abort if the terminal window was closed or if the network connection to the PC failed ( see also Section Scroll mode above ). Start the UA Server as a detached background process: nohup java cp <PUTDIR>/ua/ ua.jar UaServer &. Look at the standard output of the UA Server to see whether it starts up correctly. The last message shows that the server is ready to receive UA GUI connections. UaServer> Upgrade Assistant Server (Version 2.0) UaServer> Running on host horizon.saptest.be (10.191.23.101) UaServer> Temporary directory is '/usr/sap/ put/ua' UaServer> Upgrade directory is '/usr/sap/ put' UaServer> Stable storage file '/usr/sap/put/ ua/uastate' read UaServer> Property file '/usr/sap/put/ua/ UaServer.properties' read UaServer> Property file '/usr/sap/put/ua/ UaTextE.properties' read UaServer> Waiting for UaGuis to connect at port 4241 Windows with Java SDK: (logged on as <sid>adm) java cp <PUTDIR>\ua\ua.jar UaServer Windows with Standard Java VM: (logged on as <sid>adm) jview /cp <PUTDIR>\ua\ua.jar UaServer iseries: ADDLIBLE R3UP ADDENVVAR ENVVAR(PASE_LIBPATH) VALUE('<PUTDIR>/bin') JAVA CLASS(UaServer) CLASSPATH('<PUTDIR>/ua/ ua.jar') Port 4241 is the port used when the UA GUI runs in stand-alone mode. When it is started as a browser applet, a different port number ( 4239 ) is used. Section 9.7 provides more detail. 9.7 Start UA GUI and Log In The procedure to run the UA GUI and log on to the UA Server is slightly different depending on whether you run the UA GUI as a stand-alone application or via a browser. Starting from a Browser Open a Web browser and enter the URL: http://<upghost>:4239 www.sap-press.com 83

9 The PREPARE Process <upghost> is the host name or IP address of the host where the UA Server runs. The HTTP port of the UA Server is 4239. The SAP Upgrade main page is displayed ( see Figure 9.1 ). You can also pass the host name and port number on the command line in the form of a SAP route string, for example: java cp C:\UAGUI\uagui.jar host /H/ sapdev01/s/4241 This will skip the first screen; that is, the UA GUI will now behave as it does when you run it from a browser. 9.8 Run Time of PREPARE Figure 9.1 Initial Browser Screen For Upgrade To start the UA GUI, click on Start Upgrade Assistant. A login screen appears. On this screen enter: A freely chosen user name ( this can be your real name, as the only purpose is to identify who is currently connected to the UAGUI ) Your telephone number ( optional ) The password for the administrator role ( default: admin ) Choose Login and continue with the instructions in Section 9.9. Note: To call the UA GUI directly, use the URL http:// <server>:4239/ua/uagui.html. Starting as a Standalone Application Open a command shell on the PC and type the command to start the UA GUI as shown earlier in Section 9.5. Because at this point you have not yet identified the upgrade host a window opens asking for the upgrade host and port: Host name: Name or IP address of the host where the UA Server runs Port number: Accept the default 4241 ( notice that different ports, 4239 and 4241, are used depending on how you run the UA GUI ). Many factors influence the total runtime of PREPARE, and it is difficult to make a prediction. You should typically expect a runtime of between four and eight hours. Although there are some lengthy phases during which PREPARE runs unattended, the program will request user input at many different points. This means that PREPARE is not suitable to run overnight without human monitoring. 9.9 Input Up to Phase Selection Note: For better readability, the PREPARE dialogs in this section are shown as text ( not as actual screen shots ) on a shaded background. User input appears in bold. Whenever an input screen requires further explanation, this information is presented in plain text. In the UA GUI window, choose Administrator Start PREPARE. Welcome to the SAP upgrade control program. Continue. SAP System ID Confirm the system ID. Select type of database Select your DBMS, click OK. Start import of data from Data Carrier? Choose Import, click OK. Enter mount point for Data Carrier : Type the path of the Upgrade Master CD. The archives are unpacked. SAP UPGRADE CONTROL PROGRAM Continue. 84 Galileo Press 2006.

9.13 Input for Parallel Processing The following options are available: select: Display screen for selecting PREPARE modules status: Display the statuses of the PREPARE modules exit: Exit PREPARE help: Getting help about PREPARE Choose Select. Select the PREPARE modules Mark all phases and click OK. Note: Ignore the fact that some phases are marked as mandatory and others are not. Always execute all phases. You selected the following PREPARE modules: ( The phase list follows scroll down to see the radio buttons. ) Choose Execute, click OK. SAP System ID SAP System Host Instance number The values shown should be OK. At this point you can upload the new kernel ( see below ). To bind the new kernel into the upgrade, do the following: 1. Log on as sidadm. 2. Unpack the SAPEXE*.SAR and SAPEXEDB.* packages you downloaded from the SAP Service Marketplace ( see Section 8.5; heading Support Packages ): cd <PUTDIR>/exe SAPCAR xvf <downloadpath>/sapexe*.sar SAPCAR xvf <downloadpath>/sapexedb*.sar If the extraction was successful for both archives, reply OK in the PREPARE window. 9.12 Input for Server and Path Names 9.10 Entering the CD/DVD Mount Points Mount points for DVDs Enter the paths of the online copies of the upgrade media. The path of the Upgrade Master medium is already filled in. You must still enter the paths for the kernel medium, the language media and the eleven upgrade media. Fortunately you only have to do this once! Unlike earlier versions of the UA GUI, this one lets you copy/paste path names. For this, use the right mouse button, not Control- C/Control-V. Fill in the paths for all media. When you are done, press > or >> till you reach the last screen; here the OK button is enabled. 9.11 Kernel Extraction and Optional Replacement The extraction of the kernel now begins. If you plan to upgrade the SAP kernel to a higher level than the one delivered on the upgrade media, then you can already bind the new kernel into the upgrade when PREPARE next stops for further input. PREPARE now requests information about the server environment and various directory paths needed for the upgrade. Kernel path Press OK. Database ID Database host Values shown should be OK. DDIC password Enter and confirm password of user DDIC in client 000. Instance profile Default profile Start profile Values shown should be OK. Batch host Set to host of Central Instance ( default ). 9.13 Input for Parallel Processing Maximum uptime processes See below. www.sap-press.com 85

9 The PREPARE Process R3trans processes See below. Maximum SYNC time Enter 120. The value for Maximum uptime processes determines the number of parallel tasks that will run in the shadow instance during the dictionary activation phase. With the downtime-minimized strategy, these tasks will run together with normal use of the system. Values of 3 to 5 are reasonable. R3trans processes sets the number of parallel import processes ( R3trans ) during the upgrade. The phases most affected by this are SHADOW_UPGRADE ( an uptime phase in the downtime-minimized mode ) and TABIM ( table data import; always in downtime ). Too high a number may overload the server and also lead to contention between the different imports. Too low a value needlessly lengthens the duration of the upgrade. A suitable value in most cases is 4. The SYNC time controls internal buffer synchronization. Do not change this value. 9.14 Further Input for Path Names EPS root Local SYSLOG path Values shown should be OK. Central SYSLOG path Press OK. STARTSAP path Path ( kernel directory ) should be OK. The vague reference to the SAP Service Marketplace in this prompt is not of much use. Note 805390 is more informative. SAP Solution Manager Key = Enter the upgrade key. See Section 8.12 for instructions. 9.16 Input for MCOD Is there more than one system running in this database? (MCOD: Multiple components in one database) Enter No unless you are upgrading an MCOD system. The dialog shown here is for a non-mcod configuration. This covers most situations. 9.17 Tool Import The PREPARE module Import will be started now. During this module programs, structures, and table entries required by PREPARE are imported (the so-called "tool import"). Note: This can cause a loss of performance in R/3 In rare cases, a concurrent transport via the transport directory may disturb the tool import. Please avoid any concurrent import during this PREPARE module. Continue. 9.15 Upgrade Key ( from SAP Solution Manager ) The SAP Solution Manager Key is required for the upgrade. Further informations can be found in the upgrade guide, the SAP Service Marketplace and SAP note 805390! Continue. PREPARE will duly warn you that the import may cause some pressure on the server. Although in practice this is rarely problematic, you may choose to wait for a quieter period before confirming this prompt.
