Pre-requisites for Installing eG Manager

A set of pre-requisites should be fulfilled before you start installing eG Manager in your environment. These requirements are clearly stated in the following sections:

For Windows Platforms

For the eG manager to function, the Windows system on which the manager is being installed should support:

  1. Windows 10 (OR) Windows 11 (OR) Windows 2016 (OR) Windows 2019 (OR) Windows 2022 (OR) Windows 2025
  2. Only systems with a static IP address (i.e. no DHCP address) should be used for installing the eG manager
  3. A minimum of 8 GB RAM would be required
  4. A minimum of 100 GB disk space

  5. For the eG database, use Oracle database server (version 18C / 19c / 21c) / Microsoft SQL Server (2014 / 2016 / 2017 / 2019 / 2022 / 2025) / Microsoft Azure SQL database / Microsoft SQL Server (version 2016 /2017) installed on Linux operating system / Azure SQL Managed Instance / Amazon RDS instance

    Note:

    • When using an Oracle database server / Microsoft SQL server as the eG backend, you can install the database on the same system as the eG manager, or on a separate system. However, for implementations with 100 monitors or more, the database should ideally be hosted on a separate system. Both the eG manager and the eG database can be hosted on virtual machines or physical machines.
    • Moreover, when using a Microsoft SQL Server backend, ensure that the installation of the server is performed in the case-insensitive mode. Also, make sure that the Simple Recovery mode is set. If you choose to manually create the Microsoft SQL database as the backend while installing the manager, then, the collation of the database should be SQL_Latin1_General_CP1_CI_AS.

    • Also, make sure that the following requirements are fulfilled:

    • To ensure high availability of the eG database, you can optionally enable any of the following HA configurations for the eG database:

      • Oracle Real Application Cluster (Oracle RAC), for an eG database on Oracle;
      • Microsoft SQL Cluster / SQL AlwaysOn Availability Group, for an eG database on Microsoft SQL;
  6. All latest versions of Edge, Chrome, and Mozilla Firefox browsers are supported. To ensure peak browser performance, ensure that the browser settings recommended in Recommended Browser Settings are implemented.
  7. A valid eG license

Note:

The eG manager is bundled with a Tomcat server. Before installing the eG manager therefore, make sure that no other Tomcat server pre-exists on the target manager host.

For Linux Platforms

For the eG manager to function effectively, the Linux system on which the manager is being installed should support:

  • Red Hat Enterprise Linux 5 (or higher) (or) CentOS v5.2 (or above)

  • For the eG database, use Oracle database server (version 18C / 19c / 21c) / Microsoft SQL Server (2014 / 2016 / 2017 / 2019 / 2022 / 2025) / Microsoft Azure SQL database / Microsoft SQL Server (version 2016 /2017) installed on Linux operating system / SQL Managed Instance / Amazon RDS instance

  • A minimum of 100 GB of disk space free
  • All latest versions of Edge, Chrome, and Mozilla Firefox browsers are supported. To ensure peak browser performance, ensure that the browser settings recommended in Recommended Browser Settings are implemented.
