US Patent 7703097 Auto-commit processing in an IMS batch application

A DLI call from the batch application is intercepted, wherein the DLI call is made for the purpose of accessing a hierarchical database. It is then determined if the access to the hierarchical database is a checkpoint trigger event. A segment counter for a trigger segment in a checkpoint trigger for the checkpoint trigger event is incremented if the trigger segment is identified by the DLI call. The segment counter is compared to a segment commit threshold in the checkpoint trigger and commit point processing is performed on behalf of the batch application if the segment counter is in a predetermined relation to the segment commit threshold.
