Syncsort MFX Modernization Guide

Syncsort MFX is a high-performance sorting and data manipulation software designed for mainframe environments. It efficiently handles large datasets and integrates with other mainframe systems.

Syncsort MFX can be invoked via JCL (Job Control Language) in batch jobs or called directly from application programs. It supports various input and output data formats.

Key features include high-speed sorting, data manipulation, Db2 data access, and high-speed IEBGENER replacement using SYNCGENR or BETERGENR.

Optional extensions include PROC MFX (SAS SORT replacement), MFX PipeSort (parallel sorting), MFX ZPCopy (zIIP offload for copy), and MFX ZPCompress (zIIP offload for DFSMS compressed datasets).

Common operations include SORT, MERGE, COPY, and data manipulation using statements like INCLUDE, OMIT, and BUILD. Configuration is primarily done through JCL parameters.

Syncsort MFX does not expose REST or SOAP APIs. Integration is typically done through native calls from COBOL, Assembler, or other mainframe programming languages.

The main components include the sort engine, data access modules, and optional extensions like PipeSort. Communication occurs through internal subroutine calls and shared memory.

Syncsort MFX interacts with Db2 through standard Db2 interfaces. It uses VSAM datasets and sequential files for storage.

Syncsort MFX improves processing efficiency, reduces CPU usage, and accelerates data processing tasks, leading to cost savings and faster turnaround times.

By optimizing sort processes and offloading tasks to zIIP processors (with extensions like MFX ZPCopy and MFX ZPCompress), Syncsort MFX minimizes resource consumption.

The high-speed IEBGENER replacement (SYNCGENR or BETERGENR) reduces the time and resources required for data copying and generation tasks.

Syncsort MFX integrates with z/OS security systems such as RACF, ACF2, and Top Secret for authentication and authorization.

It leverages the z/OS access control model, typically using ACLs managed by RACF or similar security products.

Data encryption can be implemented using DFSMS encryption features, which protect data at rest. Syncsort MFX itself does not provide encryption.

Syncsort MFX provides detailed logging of sort activities, which can be integrated with z/OS security and audit logging systems.

Administration is primarily done through JCL and system parameters. Monitoring is achieved through SMF records and log files.

User management is handled by the z/OS security system (RACF, ACF2, Top Secret). Syncsort MFX uses these systems for authentication and authorization.

Key configuration parameters include sort work space size, buffer sizes, and the number of parallel tasks. These are set via JCL parameters.

Syncsort MFX provides SMF records and log files that can be used for performance monitoring and troubleshooting. These logs capture details about sort execution and resource usage.
