Network

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

The location of a database must be specified by linking each database to an object of type Virtual Machine and each virtual machine to an object of type Network. A current network can be defined in the Miscellaneous section of the General defaults of Predict or with the command SET VM virtual-machine-ID.

The current network will be taken as default for virtual machine objects if no network is specified.

Links between virtual machines and networks are established by entering the network in the parameter "Belongs to NW" of the virtual machine. A virtual machine cannot be linked via "Belongs to NW" to a network using the link editor.

See Defining the Distribution of Data in Predict in the section Adabas Vista in the Predict and Other Systems documentation for a description of how to define the distribution of data.

This document covers the following topics:

• Network Maintenance Menu

• Add a Network Screen

• Network-Specific Maintenance

• Network Retrieval

Network Maintenance Menu

The Network Maintenance menu is called with function code M and object code NW in a Predict main menu, or with the command MAINTAIN NETWORK.

The parameters are described under Global Attributes.

All functions are described in the section Maintenance in the Predict Reference documentation. The function Purge Network is described in the section Purge Network - Code P.

Add a Network Screen

The following screen is displayed for the Add a Network function. The Copy and Modify screens are similar.

Abstract    Zoom: N

The parameters are described under Global Attributes.

Network-Specific Maintenance

Standard maintenance functions are used for maintaining networks. These are described in the section Maintenance in the Predict Reference documentation.

The special rules applying to function Purge Network are described below.

Purge Network - Code P

The following rules apply:

• A network that is linked to a virtual machine via "Uses VM" cannot be deleted.

• The network defined as current network in the General defaults cannot be deleted.

Network Retrieval

Standard retrieval functions are described in the section Retrieval in the Predict Reference documentation. The network-specific function Vista Numbers is described below.

Vista Numbers - Code N

Displays information on the use of Vista numbers in list form (see sample output below).
