What is a Portal Server?

A Portal Server is a VISULOX instance responsible for:

  • handling user authentication

  • managing sessions

  • serving the administration interface

  • coordinating application access

In clustered environments, multiple Portal Servers can work together to provide:

  • high availability

  • load distribution

  • redundancy

Each Portal Server has a defined role within the cluster.

Roles

Master

The Master Portal Server is the primary node in the cluster.

It is responsible for:

  • Cluster coordination

  • configuration management

  • synchronization with other nodes

Only one Master server exists within a cluster.

Worker

A Worker Portal Server operates as a secondary node and:

  • handles user sessions

  • executes workload assigned by the Master

  • contributes to load distribution and scalability

Portal Servers Page Overview

The Portal Servers page provides an overview of all configured Portal nodes.

For each server, the system displays:

  • Server name

  • Server IP address

  • External DNS name

  • Current status (Active / Inactive)

  • Cluster role (Master / Worker)

From this page, administrators can:

  • add a new Portal Server

  • review server details

  • modify configuration

  • monitor cluster status

Managing Portal Servers

Adding a New Portal Server

Click + New Portal Server.

Enter the required server details.

Save the configuration.

After configuration, the server can join the cluster.

Portal Server Configuration (Field-by-Field)

1. Name
