ABSTRACT:
The present invention discloses a solution that automatically decomposes a batch process into multiple units of work without changing code of a pre-existing batch application. In the solution, the batch application is first analyzed to identify a set of processing segments or units of work, where each unit of work is of a size that minimizes interference with other data accesses. Once each unit of work is defined, these units can execute one at a time. A syncpoint can be established for each unit before it is executed, which locks the records included in the unit. After the unit of work executes, the record lock can be released and a new syncpoint can be established for the next unit. If an execution problem occurs, execution for the unit of work can be terminated and chances can be restored to the syncpoint.
