PowerCenter 8 Domain
PowerCenter has a service-oriented architecture that provides the ability to scale
services and share resources across multiple machines. It provides the PowerCenter
domain to support the administration of the PowerCenter Services. Domain is the
primary unit for management and administration of services in PowerCenter. It has the
following components
 One or more nodes
Node is a logical representation of a machine in a domain. Domain may contain
more than one node. The node that hosts the domain is the master gateway for
the domain. We can add the other machines as nodes in the domain and
configure the nodes to run Integration Services and Repository Services. All
service requests from other nodes in the domain go through the master gateway.
 Service Manager
Service Manager is built in to the domain to support the domain and the
application services. The Service Manager runs on each node in the domain.

PowerCenter 8 Overview
PowerCenter 8 Repository
PowerCenter repository resides in a relational database. Repository database tables
contain the instructions required to extract, transform, and load data. PowerCenter
Client applications access the repository database tables through the Repository
Service. The repository consists of database tables that store metadata. Metadata
describes different types of objects, such as mappings or transformations, that we can
create or modify using the Client tools.
Integration Service uses repository objects to extract, transform, and load data. The
repository also stores administrative information such as user names, passwords,
permissions, and privileges. we add metadata to the repository tables when you
perform tasks in the PowerCenter Client application, such as creating users, analyzing
sources, developing mappings or mapplets, or creating workflows. The Integration
Service reads metadata created through the Client application when you run a
workflow. It also creates metadata, such as start and finish times of a session or
session status.

PowerCenter 8 Overview
We can administer the repository using the Repository Manager client tool and we can
also develop global and local repositories to share metadata.
• Global repository
Global repository is the hub of the repository domain. Use the global repository to
store common objects that multiple developers can use through shortcuts. These
objects may include operational or Application source definitions, reusable
transformations, mapplets, and mappings.
• Local repositories
Local repository is any repository within the domain that is not the global
repository. Use local repositories for development. From a local repository, we
can create shortcuts to objects in shared folders in the global repository. These
objects include source definitions, common dimensions and lookups, and
enterprise standard transformations. we can also create copies of objects in nonshared folders.
