  • System and method for updating non-VSAM data set control information for data transferred from a source to a target
    Patent number: 6189015
    Abstract: A system and method for maintaining non-VSAM data set control information when moving a non-VSAM data set from a source volume to a target volume, even if the data set is not read into a host. After data is moved from the source volume set to the target volume set, each target volume is analyzed to determine the last track and record used by the data set and this information is recorded the in each target volume virtual table of contents (VTOC). In one embodiment where the volume geometry is identical, the last track and record are determined by examining the last target volume not completely filled with data from the data set.
