Configuration Changes

To support network transactions, several configuration attributes and a configuration

record have been added to the RDF configuration file.

NETWORK Attribute

This attribute, located in the RDF configuration record, specifies whether or not you are

configuring an RDF network.

To set this attribute, use the following RDFCOM command:

SET RDF NETWORK {ON | OFF}

When this attribute is set to OFF (the default value), RDF takeover operations execute

just as they have in the past, and database consistency is not guaranteed for

transactions spanning more than one backup system.

When this attribute is set to ON, the RDF subsystem can guarantee backup database

consistency across multiple RDF systems configured within an RDF network.

NETWORKMASTER Attribute

This attribute, located in the RDF configuration record, specifies whether or not the

particular system is the master of the RDF network. Each RDF network has one, and

only one, network master.

To set this attribute, use the following RDFCOM command:

SET RDF NETWORKMASTER {ON | OFF}

When this attribute is set to OFF (the default value), the particular system is not the

network master.

When this attribute is set to ON, the particular system is the network master of the RDF

network. Note that if this attribute is set to ON, the NETWORK attribute must also be

set to ON.

Network Configuration Record

This configuration record contains some or all of the following network attributes:

PRIMARYSYSTEM system-name

BACKUPSYSTEM system-name

REMOTECONTROLSUBVOL subvolume-name

PNETTXVOLUME volume-name
