Using resources with PowerCenter requires coordination and communication between the domain administrator and the workflow developer. The domain administrator defines resources available to nodes. The workflow developer assigns resources required by Session, Command, and predefined Event-Wait tasks. To coordinate resource usage, you can use a naming convention for file/directory and custom resources.
Use the following naming convention:
For example, multiple nodes in a grid contain a session parameter file called sales1.txt. Create a file resource for it named sessionparamfile_sales1 on each node that contains the file. A workflow developer creates a session that uses the parameter file and assigns the sessionparamfile_sales1 file resource to the session.
When the PowerCenter Integration Service runs the workflow on the grid, the Load Balancer distributes the session assigned the sessionparamfile_sales1 resource to nodes that have the resource defined.
