PowerCenter session always runs on a different node than the one selected

Problem
There are two nodes (node01 and node02 ) running on a grid. The session must be run on node01 because that is where the source file is located. Selecting node01 in the Resources option on the General tab does not force the session to run on node01, rather it randomly chooses both nodes for running session, sometimes node01, other times node02. Is there a setting to always run session on node01?
Cause
This behavior occurs when the IgnoreResourceRequirement Integration Service property is enabled.
Solution

To resolve this set IgnoreResourceRequirement to "No" as follows:

• In the Administration Console, select the Integration Service.


• Under the Properties tab select Advanced Properties > Edit .


• Clear the IgnoreResourceRequirements property.


• Restart the Integration Service.


• Run the workflow.
