Several installation sysparms are available to alter the data set selection and processing techniques.
Can be used to cause a new tape to be mounted when the year portion of the expiration date changes. Default processing sorts all data sets to be migrated into descending sequence by expiration date, but does not cause a volume switch when the year changes.
Can be used to permit expired data sets to be migrated. Default processing is for unexpired data sets only.
Can be used to suppress the selection of data sets that have all zeros for an expiration date. Default processing treats them as unexpired and as candidates to be migrated.
Can be used to change the catalog action for uncataloged non-GDG data sets. The default value is Y, which means to catalog all non-GDG data sets migrated to tape that were not cataloged before.
Can be used to change the catalog action for uncataloged GDG data sets. The default value is N, which means no change is made in the catalog when an uncataloged GDG is migrated to tape.
Can be used to create a duplicate backup copy concurrent with the primary Sequential Migration tape(s). An entry in the MIGRECAT subfile is also created if this SYSPARM is set to 'Y'. The default is 'N' which does not produce the copy.
Can be used to set an absolute limit to the number of data sets migrated to each output tape. The default is set at 9999.
Can be used to specify tape density for simulate mode processing. It defaults to 6250. In live mode, the actual density used is properly obtained.
Can be used to cause messages to be printed that state why a data set was bypassed for processing.
Can be used to also select RACF-protected data sets for migration. By default, CA Disk will bypass RACF-protected data sets from migration.
