Application_Commit_UR (SRRCMIT)

Call the Application_Commit_UR service to indicate that the changes for the unit of recovery (UR) are to be made permanent. A UR represents the application's changes to resources since the last commit or backout or, for the first UR, since the beginning of the application. In response to the call, RRS requests that the resource managers make the changes permanent.

Certain resource managers, such as a communications manager, can issue a TAKE_COMMIT return code to an application that has requested changes to resources. In response to the TAKE_COMMIT code from the resource manager, the application should request the changes to the resources:

If all of the change requests are accepted, call the Application_Commit_UR service again.
If any of the change requests are not accepted. call the Application_Backout_UR service to back out the changes.
