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 preparation, which is the second 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 prepare the standard installation of your SAP System. You have to complete the following preparations:

Check the hardware and software requirements using the Prerequisites Checker.

You check the hardware and software requirements for your operating system (OS) and the SAP instances using the Prerequisite Checker tool. The Prerequisite Checker provides information about the requirements that you need to meet before you start the installation. The values that are checked by the Prerequisite Checker apply for the installation of development system or quality assurance system. To get precise sizing values for the production system, you have to use the SAP Quick Sizer tool that is available on SAP Service Marketplace at service.sap.com/sizing. Or you can contact your hardware vendor, who can analyze the load and calculates the requirements.
Check for the Windows file system.

You need to check that you are using the Windows File System (NTFS) on host where you want to install the SAP System and database. NTFS support full Windows security and long file names. You must use NTFS for an SAP System installation. Do not install the SAP directories on a FAT partition.

Check the Windows domain structure.

You do not need this step for a local installation. In Windows, you can implement either of the following domain models for the SAP System:

Extra domain. The SAP System is embedded in its own domain, which is specially defined for SAP. A second domain exists for the user accounts. In Windows, the SAP domain and user domain must be incorporated in a domain tree. In this tree, the user accounts must form the root domain and the SAP domain must be a child domain of this.

Single domain. The SAP System and the user accounts are included in a single domain.

For a domain installation, SAP recommended that you check that all SAP System and database hosts are members of a single Windows domain. SAP recommended this for all SAP System setups.

Reduce the size of the file cache (if required).

The Windows file cache directly competes with SAP programs for memory. Therefore, you should adjust the file cache.

Grant user rights for the installation (if required).

You have to grant the required rights and privileges that authorize you to install the SAPinst tool and the SAP System. If you attempt the installation without the required authorization, the system aborts. If necessary, you have to ask the system administrator to grant you the necessary authorization before you start the installation.

Perform a domain installation without being a domain administrator (if required).

If you are not granted domain administrator rights, you can perform the installation as a domain user who is a member of the local Administrators group. In this case, the domain administrator must prepare the system for you appropriately. The domain administrator has to:

Create the new global group SAP_[SAPSID]_GlobalAdmin.

Create the two new SAP System users [sapsid]adm and SAPService[SAPSID].

Add the users [sapsid]adm and SAPService[SAPSID] to the newly created group SAP_[SAPSID]_GlobalAdmin.

Prepare the SAP System transport host.

You need to prepare one transport host in the SAP System. This host has the function of controlling the import or export of files between the current SAP System and other SAP System (for example, a test or development system). The transport host use the usr\sap\trans directory to temporarily store files that have been exported from one system and waiting to be imported into another system. Depending on your requirements, you can decide to use the central instance host, the dialog instance host, or any other host as the transport host.

Install the SAP front-end software.

For the installation, make sure that the front-end software is installed on at least one host machine in your system environment. To simplify the administration of your SAP System, SAP recommended you install the software on the central instance host. With the SAP front-end installation software, SAPSetup, you can optimize the deployment of SAP GUI to thousands of clients. You can easily tailor installation package to match your requirements, distribute patches, and set up automatic update processes for your clients.

Generate the SAP Solution Manager Key.

You need to generate the Solution Manager Key because SAPinst prompts for it during the input phase of the installation.

Install the Java Runtime Environment.

You need to prepare your system for SAPinst. This includes the installation of a Java Runtime Environment (JRE), which is required both for SAPinst and the SAPinst GUI. If required, you can perform a remote installation using a standalone SAPinst GUI on a separate Windows or UNIX host. This lets you perform the installation on a remote host, controlling it with the SAPinst GUI from a local host.

Prepare the installation DVDs.

You use this procedure to prepare the installation DVDs. Normally you obtain the installation DVDs as part of the installation package that you receive from SAP. However, you can also download the installation DVDs from SAP Service Marketplace. SAP recommended that you make all required DVDs available in parallel. The Export DVD and RDBMS DVD (if relevant) must be available in parallel. If you copy the installation DVDs to disk, make sure that the paths to the location of the copied DVDs do not contain any blanks. If you use network drives for mounting the export DVDs, make sure that the [sapsid]adm user has access to the UNC paths of the network drives. If the user does not yet exist, you have to create it manually before you install the database instance.

Download the installation DVDs from SAP Service Marketplace (if required).

You normally obtain the installation DVDs as part of the installation package from SAP. However you can also download installation DVDs from SAP Service Marketplace at: service.sap.com/swdc à Downloads à Installations and Upgrades à Entry by Application Group à [your solution] à [release of your solution] à [your operating system] à [your database]. If you download installation DVDs, note that DVDs might be split into several files. In this case, you have to reassemble the required files after the download. To extract the downloaded SAR files make sure that you use the latest SAPCAR version, which you can find on SAP Service Marketplace at service.sap.com/swdc. You need at least SAPCAR 700 or SAPCAR 640 with patch level 4 or higher because older version of SAPCAR can no longer unpack current SAR files.
