PowerCenter Integration Service Connectivity

PowerCenter Integration Service Connectivity

The PowerCenter Integration Service is a repository client. It connects to the PowerCenter Repository Service to retrieve workflow and mapping metadata from the repository database. When the PowerCenter Integration Service process requests a repository connection, the request is routed through the master gateway, which sends back PowerCenter Repository Service information to the PowerCenter Integration Service process. The PowerCenter Integration Service process connects to the PowerCenter Repository Service. The PowerCenter Repository Service connects to the repository and performs repository metadata transactions for the client application.
The PowerCenter Workflow Manager communicates with the PowerCenter Integration Service process over a TCP/IP connection. The PowerCenter Workflow Manager communicates with the PowerCenter Integration Service process each time you schedule or edit a workflow, display workflow details, and request workflow and session logs. Use the connection information defined for the domain to access the PowerCenter Integration Service from the PowerCenter Workflow Manager.
The PowerCenter Integration Service process connects to the source or target database using ODBC or native drivers. The PowerCenter Integration Service process maintains a database connection pool for stored procedures or lookup databases in a workflow. The PowerCenter Integration Service process allows an unlimited number of connections to lookup or stored procedure databases. If a database user does not have permission for the number of connections a session requires, the session fails. You can optionally set a parameter to limit the database connections. For a session, the PowerCenter Integration Service process holds the connection as long as it needs to read data from source tables or write data to target tables.
The following table summarizes the software you need to connect the PowerCenter Integration Service to the platform components, source databases, and target databases:
Both the Windows and UNIX versions of the PowerCenter Integration Service can use ODBC drivers to connect to databases. Use native drivers to improve performance.
