IBM Tivoli Directory Integrator
The mode of an AssemblyLine Connector defines what role that Connector
plays in the data flow, and controls how the automated behavior of the AssemblyLine
drives the Component. It determines whether to read from an input
source, write to it or both.
Connectors can be set to one of these standard modes:
These modes are discussed in the sections below. For a detailed description
of Connector mode behavior, as well as that of the AssemblyLine in general, see "AssemblyLine and Connector mode flowcharts" in IBM Tivoli Directory Integrator V7.1 Reference
- Iterator mode
Connectors in Iterator mode are used to scan a data source and
extract its data. The Connector in Iterator mode actually iterates through
the data source entries, reads their attribute values, and delivers each entry
to the AssemblyLine Flow section components, one at a time. A Connector in
Iterator mode is commonly referred to as an Iterator Connector, or just Iterator.
- Lookup mode
Lookup mode enables you to join data from different data
sources using the relationship between attributes in these systems.
A Connector in Lookup mode is often referred to as a Lookup Connector.
- AddOnly mode
Connectors in AddOnly mode, commonly referred to as AddOnly
Connectors, are used for adding new data entries to a data source.
- Update mode
Connectors in Update mode, usually referred to as Update
Connectors, are used for adding and modifying data in a data source.
For each entry passed from the AssemblyLine, the Update Connector
tries to locate a matching entry from the data source to modify with
the values of the entry attributes received. If no match is found, the Update mode Connector will add a new entry.
- Delete mode
Connectors in Delete mode, often referred to as Delete
Connectors are used for deleting data from a data source.
- CallReply mode
CallReply mode is used to make requests to data source
services, such as Web services, that require you to send input parameters
and receive a reply with return values.
- Server mode
The Server mode, available in a select number of Connectors, provides the functionality of waiting for an incoming
event, dispatch a thread dealing with the event, and send a reply
back to the originator.
- Delta mode
The Delta mode is designed to simplify the application of changes
to data by providing incremental modifications to the connected system, based
on delta operation codes.
- Link Criteria
The Link Criteria is used to tell a Connector in Update, Lookup and Delete modes how to define a match between data attributes
in the AssemblyLine and those found in the connected system.
