Chapter 8 Managing TIBCO Object Service Broker MAP Data Definitions : Task B: Specify Address, Count, and Location Parameters

Task B: Specify Address, Count, and Location Parameters
Purpose of this Step
You can use this step to specify three types of parameters:
Parameter Segment
The following example illustrates the fields used to specify address, count, and location parameters. To view additional fields, use PF11.

 
Parameter Name Typ Syn Len Dc Cls Reference
---------------- - -- --- -- - ----------------
_ ADDRESS B 4 0 A
_ COUNT B 4 C
_ LOCATION I C 16 0 L

 
Address Parameter
You require an address parameter to access storage data. This parameter must have syntax B, a length of 4, and class A (Cls field).
Count Parameter
You can use an optional count parameter to limit the number of occurrences eligible for selection by a GET or FORALL statement. This does not mean the number of occurrences that are retrieved; the number of occurrences selected is equal to or lower than the count value, and could be zero. This parameter must have syntax B, a length of 4, and class C (Cls field). If you do not specify this parameter, a default value of infinity is used.
Location Parameter
You can use an optional 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.
If you use a MAP table remotely, all storage references must be to addresses valid on the remote system.
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 name of the remote node where the full definition is located must be supplied in the Default field, Src field, or Src and Sourcename field.
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.
