TVL Information Management for z/OS

TVL Information Management for z/OS is a mainframe-based software solution designed to assist in asset, problem, and change management. It provides features such as inventory control, problem tracking, change management, and ad hoc reporting. The system helps organizations maintain an accurate database of hardware and software assets, track and manage problem tickets, and manage change requests.

Key components include the asset database, problem tracking module, change management module, reporting engine, and security subsystem. These components communicate through internal APIs and data access layers. The system likely uses a DB2 database on z/OS for storing asset data, problem tickets, and change requests.

It supports authentication methods such as LDAP, RACF, and potentially multi-factor authentication depending on the configuration. It uses role-based access control (RBAC) to manage user permissions. Administrators can manage the system through a TSO/ISPF interface and potentially a web console.

User management is handled through RACF or a similar security system on z/OS. Configuration parameters are managed through configuration files and online panels. Monitoring and logging capabilities are provided through SMF records and system logs.

TVL Information Management for z/OS aims to improve IT asset visibility, streamline problem resolution, and enable better change control.
