By Nitesh Jain, Infosys Technologies

Prerequisite:

• The OS is AIX 5.3.

• This document is applicable for installing Dialog Instance of ECC 6.0 systems

Introduction

Login Load balancing allows you to distribute the SAP users that login to a SAP server to additional dialog/application server instances dynamically. You can increase the efficiency of work processes by setting up multiple logon workgroups (like "ALL" or "Parallel Generators" that consist of one or more application instances.

You can assign one or more application servers to certain workgroups or specific applications. When users log on to the system, they are automatically logged/directed on to the SAP server that currently has the best performance statistics, CPU utilization and/or the fewest users.

Prerequisites for Starting Application Server Installation  

1.       If you are installing an additional dialog instance on a host other than the SAP Global Host, you must mount directories from the SAP Global Host i.e. the directories should be shared among various Application servers .

2.       If you want to install the executables locally instead of sharing them,  create <sapmnt>/<SID>/exe as a local directory only (not a link) with a minimum of 1100 MB free space.

3.       Make sure that the global transport directory is mounted on every host where you want to install an SAP instance, otherwise, the installation fails.

4.       Make sure that your operating system(OS) during installation  does not delete the contents of the temporary directory /tmp or the contents of the directories to which the environment variables TEMP, TMP, or TMPDIR point, by using a crontab entry.

Starting Application Server Installation

 1.       Create the Installation Directory

2.       Set JAVA_HOME environment

3.       Library path variables and Display Environment

4. Run sapinst for preparation for Dialog Installation
