SAP Guides: SAP ERP Central Component Installation

This documentation contains general information about SAP System installation – SAP ERP Central Component 2004 SR1 (SAP ECC 5.0), SAP ERP Central Component 2005 SR1 (SAP ECC 6.0) – on Windows when your database is MS SQL Server. It focuses on the ABAP part of the installation and covers the installation, which is the third section of the first part of the installation. For more information and for the detailed installation procedure see the documentation on SAP Service Marketplace at service.sap.com/erp-inst.

This section tells you how to perform a standard installation of your SAP System. You have to complete the planning and preparation activities, before you start the installation. You perform the following steps:

Install the MS SQL Server database software.

The SQL Server software has to be installed on each host in the system where you intend to set up an SAP instance. Depending on the type of host involved, you either have to install the software for the database client or server.

Install the SAP System using SAPinst.

Running SAPinst on Windows.

This step tells you how to install an SAP System with SAPinst. SAPinst includes a SAPinst GUI and a GUI server, which both use Java. Note the following information about SAPinst:
- When you start SAPinst, SAPinst GUI and the GUI server also start. SAPinst GUI connects to the GUI server with a secure SSL connection, and the GUI server connects to SAPinst.
- SAPinst normally creates the installation directory sapinst_instdir, where it keeps its log files, and which is located directly in the Program Files directory. If SAPinst is not able to create sapinst_instdir there, it tries to create sapinst_instdir in the directory defined by the environment variable TEMP. Keep all installation directories until the system is completely and correctly installed.
- SAPinst creates a subdirectory for each installation service called [sapinst_instdir]\[installation_service], which is located in %Program Files%\sapinst_instdir.
- The SAPinst Self-Extractor extracts the executables to a temporary directory (TEMP, TMP, TMPDIR, or SystemRoot). These executables are deleted after SAPinst has stopped running. Directories called sapinst_exe.xxxxxx.xxxx sometimes remain in the temporary directory. You can safely delete them. The temporary directory also contains the SAPinst Self-Extractor log file dev_selfex.out, which might be useful if an error occurs. If SAPinst cannot find a temporary directory, the installation terminates with the error FCO-00058.
  Prerequisites:
- You are logged on as a user with the required rights and privileges to install the SAPinst tool and the SAP System.
- You need at least 50 MB of free space in the installation directory for each ABAP installation service. In addition, you need 60-200 MB of free space for the SAPinst executables.
- If you are installing a second or subsequent SAP System into an existing database, make sure that the database is up and running before starting the installation.

Using SAPinst GUI.

The following table shows the most important functions that are available in SAPinst GUI:

Button / Function Key / Menu Entries	Description
F1	Displays detailed information about each input parameter.
Exit	Cancels the installation with the following options: - Stop Stops the installation without further changing the installation files. You can restart SAPinst to continue the installation later from this point. - Continue Continues the installation.
Log off	Stops the SAPinst GUI, but the SAPinst and the GUI server continue running.
Retry	Performs the installation step again (if an error has occurred)
Stop	Stop the installation without further changing the installation files. You can continue the installation later from this point.
Continue	Continues with the option you have chosen before.

Interrupted Installation with SAPinst.

The SAP System installation might be interrupted for one of the following reasons:

An error occurred during the dialog or processing phase

SAPinst does not abort the installation in error situations. If an error occurs, the installation pauses and a dialog box appear. The dialog box contains a short description the choices listed in the table below as well as a path to a log file that contains detailed information about the error.
- You interrupted the installation by choosing Exit in the SAPinst menu.

The following table describes the options in the dialog box:

Option	Definition
Retry	SAPinst retries the installation from the point of failure without repeating any the previous step. This is possible because SAPinst records the installation progress in the keydb.xml file. SAP recommended that you view the entries in the log files, try to solve the problem, and then choose retry. If the same or different error occurs again, SAPinst displays the same dialog box again.
Stop	SAPinst stops the installation, closing the dialog box, the SAPinst GUI, and the GUI server. SAPinst records the installation progress in the keydb.xml file. Therefore, you can continue the installation from the point of failure without repeating any of the previous steps.
Continue	SAPinst continues the installation from the current point.

The following table describes the steps to restart installation, which you stopped by choosing stop, or to continue an interrupted installation after an error situation:

Alternative	Behavior
Run a new installation	SAPinst does not continue the interrupted installation. Instead, it moves the content of the old installation directory and all specific-installation files to the backup directory. Afterwards, you can no longer continue the old installation. For the backup directory, the following naming convention is used: [log_day_month_year_ hours_minutes_seconds] (for example, log_20_Dec_2007_18_21_28)
Continue old installation	SAPinst continues the interrupted installation from the point of failure.
