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.
