Abstract:
A system writes to a replicated direct access storage device (DASD) a record of each step within a job as each step begins and as each step completes. The records are maintained on the replicated DASD for a predetermined period of time. The predetermined period of time is, for example, the greatest amount of lag in replication of all storage systems operating within the system. The records are stored, for example, in an open jobs and datasets (OJD) file, where the file itself is a dataset. The dataset is written to by an online task (e.g., OJDSTC) which gathers input from two sources. Upon job completion, the records are stored, for example, in an OJD journal and removed from the OJD file.
