Permanent Dataset Title given to a dataset that is kept beyond the execution phase of the jobstream that creates it. Permanent DASD and tape datasets must be cataloged upon creation to permit data management operations and jobstream processing. Technical Service approves, allocates, and catalogs the initial use of all permanent production DASD datasets and tape GDGs. When referring to a pre-existing dataset with JCL, specify the dataset dsname and the operating system will dynamically locate the dataset and automatically recall an inactive dataset if applicable. Planning New development DASD requirements must be requested in advance to permit the acquisition of additional hardware if needed.
Instructions are on the backside of the form.
This is the only level at which datasets are directly accessible by the client. Unused space will be released at dataset close. Unused space will be released at dataset close. Unused space will be released at dataset close. A 3480 tape dataset that consumes up to one 3480 tape cartridge may be a candidate for migrating to DASD via the use of this mgmtclas.
