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"

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

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.

Output Options for Virtual Machine Retrieval

The output options valid for this object type are identical to those for object type dataspace. See Output Options for Dataspace Retrieval.
