Secure Communication for Workflows and Sessions
By default, when you enable secure communication option for the domain, Informatica secures the connection between the Data Integration Service and PowerCenter Integration Service and the DTM processes.
In addition, if you run PowerCenter sessions on a grid, you can enable an option to secure the data communication between the DTM processes.
To enable secure data communication between DTM processes in PowerCenter sessions, select the
Enable Data Encryption option for the PowerCenter Integration Service.
PowerCenter sessions require more CPU and memory when the DTM processes run in secure mode. Before you enable secure data communication between DTM processes for PowerCenter sessions, determine whether the domain resources are adequate for the additional load.
