Total DASD – Dataset Management

FDSO offers an integrated platform for dataset reallocation, migration, compression, space release and expansion, directory management, and catalog management. Installations can maximize returns on their investment in DASD by using FDSO's powerful selection language to locate over-allocated, under-used, or misplaced datasets and adjust them to installation standards.

FDSO Features

• Data set maintenance, including the reallocation of VSAM and non-VSAM files to relocate data sets, defragment individual data sets or DASD pools, release unused space, and convert to or from SMS.
• Non-intrusive defrag incrementally reclaims wasted space on an active volume without locking out other access to the volume.
• Comprehensive and easy-to-read reports, providing individual data set information, catalog display and error checking, standard and custom reports.
• Customizable Executive Information reports from either host-based report writers or workstation-based graphical display packages.
• Standards enforcement, including exception reporting and correction for data set naming, size, placement, and utilization.
• Enterprise-wide PDS management, offering verification, compression, and directory block optimization.
• Catalog and volume maintenance, including extensive catalog error checking and diagnosis, catalog- and volume-level “scratch” functions, and the ability to uncatalog and recatalog data sets.

FDSO Applications

• Compress all PDSs on all online DASD volumes and ensure that they have at least 20% free space and 10% free directory blocks before running the nightly update jobs.
• Reallocate all data sets belonging to a specified SMS data class that have gone into multiple extents.
• Ensure that all SMP/E data sets have at least 25% free space before installing maintenance.
• Scratch and uncatalog all permanent data sets from system work volumes on a nightly basis.
• Report the names of all data sets that reside on TSO volumes and either use less than 20% of their allocated space or have not been referenced within the last year.
• Redefine all VSAM data sets residing on a specified range of volumes that have had more than 50% of their CAs split.
• Identify data sets that do not meet installation naming or allocation specifications and create an extract data set that can be easily downloaded for use in a PC-based executive information system. FDSO can also be used to replace older, less efficient DASD utilities, yielding savings on monthly maintenance costs while increasing functionality.
