TWAIN troubleshooting can be divided into two sections: Acquiring the scanner through an ICA session Acquiring the image through the scanning process. Section 1: Acquiring the scanner through an ICA session Ensure that the server edition is set to Advanced or higher. Ensure that the server version is set to 4.0 or higher. Ensure that [...]

The high availability monitor is a virtual entity that monitors an interface. Youmust disable the monitor for the interfaces that are not connected or being usedfor traffic. When the monitor is enabled on one of the interfaces and the status ofthis interface is DOWN, the state of the node becomes NOT UP. In a highavailability [...]

To steps to set up a high availability environment, configure one NetScaler as primary and another as secondary. Perform the following tasks on each of the NetScalers: • Add a node. • Disable high availability monitoring for unused interfaces. Adding a Node A node is a logical representation of a peer NetScaler. It identifies the peer unit using [...]

To set up a NetScaler using the Configuration Utility, you need an administrative workstation or laptop on the same network as the NetScaler. If you prefer to connect the workstation directly to a NetScaler, use an Ethernet crossover cable.You also need version 1.4.2_04 or higher of the Java® runtime environment. First-time configuration includes changing the [...]

A NetScaler is usually deployed in front of a server farm and functions as atransparent TCP proxy between clients and servers, without requiring any client side configuration. This basic mode of operation is called Request Switching technology and is the core of NetScaler functionality. Request Switching enablesa NetScaler to multiplex and offload the TCP connections, [...]

A NetScaler functioning as an L2 device is said to operate in L2 mode. In L2mode, the NetScaler forwards packets between network interfaces when all of thefollowing conditions are met: • The packets are destined to another device’s media access control (MAC)address. • The destination MAC address is on a different network interface. • The [...]
