Installation and Configuration Overview

Informatica Vibe Data Stream for Machine Data

(

VDS

) is a highly available, distributed, real-time application that collects and aggregates machine data. You can collect machine data from different types of data sources, transform the data, and write it to different types of data targets.

When you run the VDS installer, it installs the VDS components.

VDS includes the following components:

Administrator Daemon: The
Administrator Daemon
is a process that collects statistics and state information from all VDS Nodes, aggregates the information, and sends them to the Administrator tool. The
Administrator Daemon
sends VDS Node configuration and VDS license details to Apache ZooKeeper. The
Administrator Daemon
runs an HTTP server. The
VDS Node
s use the HTTP server to fetch configuration and libraries from the Administrator Daemon. The database stores configuration details.; The
Administrator Daemon
installation process also installs the UM Topic Resolution Daemon (LBMRD) and a persistent store. The persistent store provides storage to message streams.
VDS Node s: A
VDS Node
is a Java program within which source services and target services exist. You can run multiple source services and target services on a single
VDS Node
. Source services collect data from data sources and publish the data. Target services receive and write that data to a data target.; You install
VDS Node
s on all the hosts on which you want to run source services or target services. The
VDS Node
s download plugins from the
Administrator Daemon
, and the configuration from Apache ZooKeeper.
Apache ZooKeeper: Apache ZooKeeper is a centralized service that maintains the configuration information of the
VDS Node
s in a deployment. You can deploy ZooKeeper as a standalone instance or, for reliability, as a cluster called a ZooKeeper ensemble. When you start a
VDS Node
, it fetches its configuration information from ZooKeeper.

You install the VDS components on the machines where PowerCenter is installed. Ensure that you install the

Administrator Daemon

on the gateway nodes of the Informatica domain. The

VDS Node

and Apache ZooKeeper can be installed on other machines. After you complete the installation process, log in to the Administrator tool, create and configure the Vibe Data Stream service.
