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 ( 2012 / 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.

    • 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 (2012 / 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.
