z/OS Considerations - Parallel Transporter

z/OS Considerations

The vigil window feature is not available for z/OS PDS files.

Load distribution of input files across instances are based on file count rather than file size.

VSAM Files on z/OS

If a VSAM file is changed or updated between checkpoints, the results of the restart are unreliable.

VSAM Alternate Indexes

KSDS/ESDS alternate indexes can be read sequentially using the pathname. But checkpoint/restart is not supported for KSDS/ESDS alternate indexes.
