# Virtual Machine

Since data can be distributed across several databases, the exact location of data storage has to be specified: databases are linked to objects of type Virtual Machine and virtual machines are linked to objects of type Network.

The Predict object virtual machine identifies the hardware and operating system environment of a database.

See the section Adabas Vista in the Predict and Other Systems documentation for a complete description of how to define distributed data structures with Predict.

In the predefined Predict metastructure, a virtual machine can have passive and active associations of the following types:

Valid passive association: | "Belongs to VM" (mandatory, default parent)
Valid active association: | "Contains DA"

Note
Links between networks, virtual machines and databases are established with the parameters "Belongs to NW" and "Belongs to VM", and not with active/passive associations.

This document covers the following topics:

- Virtual Machine Maintenance Menu

- Add a Virtual Machine Screen

- Virtual Machine Retrieval

## Virtual Machine Maintenance Menu

The Virtual Machine Maintenance menu is called with function code M and object code VM in a Predict main menu or the command `MAINTAIN VIRTUALMACHINE`.

## Virtual Machine Retrieval

#### Virtual Machine Specific Retrieval Parameters

" Belongs to NW" - only virtual machines related to the network will be included in the report.

#### Layout of Virtual Machine Lists
