Chapter 8 Managing VSAM Data Definitions : Task C: Specify Data and Location Parameters

Task C: Specify Data and Location Parameters
You can use this optional task to specify two types of parameters:

The following example illustrates the fields used to specify data and location (illustrated) parameters. To view additional fields, use PF11.

Data Parameter
You can use a data parameter to access external data in different data sets using the same table definition or to access multiple record types or multiple occurrences. Depending on the syntax and length you assign the data parameter, TIBCO Object Service Broker interprets it as follows:
and the Syntax is
and the Length is
Any character
uses the parameters for reading multiple record types or multiple occurrences. The parameter definitions must match the primary key definition of the base table.
Location Parameter
You can use a location parameter to access external data through a peer server associated with another Data Object Broker (remote node). If you do not need to access remote data, use the D line command to delete the parameter. If you always access the external file remotely, the node from which you request the access can have either a minimal or full definition.
Minimal Definition
A minimal definition with a location parameter means you always access data at a remote node. A minimal definition consists of the following:
The location parameter indicates that you always access data at a remote node. The name of the remote node where the full definition is located must be supplied in the Default field, Src field, or Src and Sourcename fields.
The table type specified in a minimal definition does not have to match the table type of the full definition on the remote node.
Full Definition
A full table definition with a location parameter means you can access data at either the local or the remote node. The table type of the full definition must match the data on the local node. For example, a full definition of type TDS used to access TDS data on the local node can also be used to access a VSAM table with the same name on a remote node.
