VSAM File Sorting & Conversion
VSAM records are fixed or variable length records organized in fixed-size byte blocks within larger divisions in disk tracks, or cylinders. IMS/DB and DB2 are implemented atop of VSAM and use its data structures.
VSAM is not, however, compatible with many other applications, and so you
require a tool that can not only process VSAM data, but also one that can
convert other file formats from and to VSAM.
VSAM file support is available when CoSort is shipped to Clerity customers using the UniKix BPE and TPE software for re-hosting their sort operations from
JCL sort software. For more information about the use of the CoSort package in mainframe sort/merge software migrations, see:
Solutions > Sort Migration
The CoSort Sort Control Language (SortCL) program recognizes VSAM as an internal /PROCESS (i.e. file format)
for the purpose of VSAM file collation, conversion, and creation in the MBM environment.
If you do not use Clerity software and require VSAM file conversion, flatten
it on the mainframe with the REPRO option in IDCAMS. Then, use CoSort's SortCL tool (or IRI's data migration tool, NextForm) to transform or convert the file and its data types to one of the target
formats listed on the left.
