Commitment Control—Scenario

The ability to scope a shared open data path (ODP) to the application is useful in the area of commitment control.

Assume that you want to use a file under commitment control but that you also need it to use a shared ODP. Without ILE, if one program opens the file under commitment control, all programs in the job have to do so. This is true even if the commitment capability is needed for only one or two programs.

One potential problem with this situation is that, if any program in the job issues a commit operation, all updates are committed. The updates are committed even if logically they are not part of the application in question.

These problems can be avoided by running each part of the application that requires commitment control in a separate activation group.
