MultSess Modernization Guide

MultSess is a 3270 session manager that allows users to connect to multiple 3270 VTAM applications from a single 3270 session. It simplifies access to different mainframe applications without requiring multiple dedicated sessions.

MultSess is an application that enhances 3270 terminal access. It provides a way to manage and switch between multiple VTAM applications within a single terminal session, improving user efficiency.

Organizations that rely on mainframe applications accessed through 3270 terminals can benefit from MultSess. This includes enterprises in industries such as banking, finance, insurance, and government, where multiple mainframe applications are used daily.

A company should consider using MultSess when its users need to access multiple 3270 applications frequently and want to avoid the overhead of managing multiple terminal sessions. It is especially useful when users switch between applications regularly.

Alternatives to MultSess include CL/Supersession, Multiterm/MVS, and InterSession. These products offer similar functionality for managing multiple 3270 sessions, but may differ in features, performance, and integration capabilities.

MultSess runs on the z/OS platform. It is dependent on the VTAM subsystem for managing 3270 terminal connections. It typically runs within an LPAR on the mainframe.

MultSess requires a z/OS environment with VTAM configured for 3270 terminal access. It also needs sufficient system resources, such as memory and CPU, to handle multiple concurrent sessions.

MultSess enhances the functionality of existing 3270 terminal access methods. It does not replace them but provides a layer of session management to improve user experience and efficiency.

MultSess is typically deployed on-premise within the z/OS environment. It requires configuration of VTAM and the MultSess application itself. Implementation involves defining application profiles and user access rights.

MultSess improves user productivity by allowing them to switch between multiple mainframe applications without disconnecting and reconnecting. This reduces the time spent managing sessions and increases overall efficiency.

Without MultSess, users would need to manage multiple 3270 terminal sessions, which can be time-consuming and cumbersome. This can lead to reduced productivity and increased frustration for users who frequently switch between applications.

MultSess can reduce operational costs by streamlining access to mainframe applications. It simplifies session management, which can lead to fewer support requests and reduced administrative overhead.

MultSess supports various authentication methods, including standard z/OS security protocols. Specific methods include RACF, ACF2, and Top Secret. These methods ensure that only authorized users can access mainframe applications.

MultSess uses an access control model based on user roles and application profiles. This allows administrators to define which users can access specific mainframe applications. The access control model is typically role-based access control (RBAC).

MultSess provides audit logging capabilities to track user access and application usage. These logs can be used to monitor security events and identify potential security breaches. The logs typically include user IDs, timestamps, and application names.

Ongoing operational requirements for MultSess include monitoring system performance, managing user access, and maintaining application profiles. Regular maintenance is needed to ensure the system runs smoothly and securely.

Administrative interfaces for MultSess typically include a command-line interface (CLI) and potentially a web-based console. The CLI is used for configuration and management tasks, while the web console provides a user-friendly interface for monitoring and reporting.

Common implementation challenges for MultSess include configuring VTAM correctly, defining appropriate application profiles, and managing user access rights. Careful planning and testing are essential for a successful implementation.
