Data set utilities

Data and storage management on z/OS

Data set utilities reorganize, change, or compare data at the data set or record level. These programs are widely used in batch jobs.

These utilities allow you to manipulate partitioned, sequential or indexed sequential data sets, or partitioned data sets extended (PDSEs), which are provided as input to the programs. You can manipulate data ranging from fields within a logical record to entire data sets. These data set utilities cannot be used with VSAM data sets.

  • IDCAMS: Use access method services for catalogs
    Although it provides other functions, IDCAMS, which is the program name for access method services, is used primarily to define and manage VSAM data sets and integrated catalog facility catalogs.
  • The IEBCOPY utility: Copy libraries (partitioned data sets)
    IEBCOPY is a data set utility that is used to copy or merge members between one or more partitioned data sets, or partitioned data sets extended (PDSEs), in full or in part.
  • The IEBDG utility: Generate test data
    The IEBDG utility provides a pattern of test data to be used as a programming debugging aid. This pattern of data can then be analyzed quickly for predictable results.
  • The IEBGENER utility: Generate (copy) a sequential data set
    The IEBGENER utility is a copy program that has been part of the operating system since the first release of OS/360. One of its many uses is to copy a sequential data set, a member of a partitioned data set (PDS) or PDSE, or a z/OS UNIX System Services (z/OS UNIX) file such as a HFS file.
  • The IEBUPDTE utility: Update data sets with fixed-length records
    The IEBUPDTE utility creates multiple members in a partitioned data set, or updates records within a member. While it can be used for other types of records, its main use is to create or maintain JCL procedure libraries or assembler macro libraries.
  • The IEFBR14 utility: Do (almost) nothing
    The utility program IEFBR14 performs no action other than return a completion code of 0; however, "running" this utility invokes other system components that perform useful tasks.
