CA VM:Sort

CA VM:Sort is a high-performance sort utility designed for the z/VM operating system. It is used to order data in a specific sequence, which is essential for reporting, data warehousing, and other data processing tasks. It supports various input and output data formats, including sequential files and VSAM datasets.

CA VM:Sort can be invoked using JCL or a command-line interface. The main system components include the sort engine, input/output modules, and control card parser. The sort engine performs the actual sorting operation, while the input/output modules handle reading and writing data.

The control card parser interprets the sorting parameters specified in the configuration files. Communication between components is primarily through internal z/VM mechanisms. Data is typically stored in sequential files or VSAM datasets.

There are no specific port or network requirements beyond those of the z/VM environment. To invoke CA VM:Sort using JCL, you specify the SORT statement, which defines the input and output datasets, sort keys, and other sorting parameters. dataset,DISP=(NEW,CATLG,DELETE),SPACE=(TRK,(10,5)) //SYSIN DD * SORT FIELDS=(1,10,CH,A) /* ``` CA VM:Sort improves data processing efficiency and reduces CPU and I/O resource usage.

It relies on z/VM security features, including access control lists (ACLs), to protect data. Competing products include Syncsort and IBM DFSORT. CA VM:Sort distinguishes itself through its tight integration with the z/VM environment and its ability to directly process VSAM datasets without intermediate conversion steps.
