Uses of PPI

Since PPI is available to any environment, not just NCL, PPI provides a simple, powerful technique for access to a product from the outside. For example, an NCL process could provide a batch program with the ability to issue selected product commands and return the results of the command to it.

PPI also provides an alternative method of communication between two NCL procedures, with no data loss if your product region terminates. The data remains queued in the PPI server address space. The NCL procedures need not be active on the same product region.
