  1. SAP R/3 Installation on WIN NT-ORACLE

  2. Standard SAP Installation • Central System Central Instance & Database Instance are in Same host. SAP Installation Methods • Standalone Database System Central Instance & Database Instance are in Different host. • MSCS SAP Installation • Known as Microsoft Cluster Server (MSCS) configuration. • The Central instance and Database are installed on two clustered machines and then configured. • To protect the system against failure. • The installation is performed in two stages. First is standard installation & second is Cluster configuration.

  3. SAP system main components • Central Instance • Database Instance • Frontends Standard SAP Installation • Configuration planning • Central system

  4. Standalone Database System Standard SAP Installation • The configuration plan must specify whether a central or standalone database system is to be installed and how many frontends and dialog instances are required. • After fixing the plan and also depending upon the availability of server, the Installation process can be started.

  5. The SAP system installation can be divided into a number of phases: Process Flow Planning Preparations SAP System Installation Post-Installation Activities

  6. In the Planning phase, you need to: • Check the hardware & software requirements. • Work out how the main system directories are to be distributed to RAID arrays in the system. Process Flow • In the Preparation phase, you need perform following tasks: • Preparations related to the operating system: • Checking the Windows file system • Checking the Windows domain structure • Updating the Dynamic Link Libraries • Reserving virtual memory • Reducing the size of the Windows cache • Preparing the Active Directory (optional) • Other Preparations: • Choosing system and host names • Preparing the SAP System transport host • Granting user rights for the installation

  7. In the Installation phase, you have to carry out following steps: • Central and database instance • Dialog instances • Frontends Process Flow • Installation of the Central and database instance: • Central System • Standalone Database System • Central instance host • Database host

  8. Central System: Actions on the centralsystem host: Installation of the Oracle server software and latest Patch using the Oracle Installer. Process Flow Installation of the R3SETUP tool using the file R3SETUP.BAT. Installation of the central instance and database instance using the R3SETUP option Install Central and Database Instance.

  9. Standalone Database System: Actions on the Central instance host: Installation of the Oracle Client software and latest patch using the Oracle Installer. Process Flow Installation of the R3SETUP tool using the file R3SETUP.BAT. Installation of the central instance using the R3SETUP option Install Central Instance.

  10. Standalone Database System: Actions on the Database host: Installation of the Oracle Server software and latest patch using the Oracle Installer. Process Flow Installation of the R3SETUP tool using the file R3SETUP.BAT. Database creation and load using the R3SETUP option Install Database Instance.

  11. Installation of the Dialog instances: When the central and database instance have been installed, you can optionally install one or more dialog instances on further hosts in the system. The actions necessary to set up a Dialog Instance: Process Flow Installation of the Oracle Client software and the latest patch using the Oracle Installer. Installation of the R3SETUP tool with the file R3SETUP.BAT. Installation of the dialog instance with the R3SETUP option Install Dialog Instance.

  12. In the Post-installation activities phase, you have to perform: • Starting and stopping the system • Logging on to the system • Installing the SAP License • Checking the services • Setting up the Transport Management System • Kernel Upgrade • Apply Support packages • Add-on Installation(if required) • Configuring the SAProuter and SAPNet - R/3 Frontend • Performing a full backup Process Flow

  13. Checking Requirements for a Central System: • Hardware Requirement • CD drive locally connected to host Hardware and Software Requirements Check
