The File Manager Service Provider for z/OS Connect now supports REST API access to IMS and DB2 data on Z. For IMS, the service provider allows API callers to read through IMS databases, position within a database, and read one or multiple segments at a time. Databases and segments can be filtered and mapped by File Manager views.
For DB2, the service provider allows API callers to read through DB2 tables and views, position within a result table, and read one or multiple rows at a time. The service also supports SQL WHERE clauses. Tables and views can be filtered and mapped by File Manager templates. As with base z/OS files such as MVS datasets, USS files, CICS VSAM, TS and TD queues, and MQ queues, the service provider can return IMS and DB2 data in a generic or specific JSON format, that is, generic across data sources, or specifically mapping segment or column data in accordance with a File Manager template or view. Full details are documented in the latest version of the File Manager for z/OS User’s Guide (v14.1.6). Watch the video at this link for detail on how to use the service provider to access IMS data, and a demonstration of the new IMS capabilities.

We are delighted to announce another HCL branded software product for IBM® mainframe customers around the world! HCL Z Data Tools (ZDT) and ZDT APIs.
ZDT is a set of tools that help you to manipulate data stored on z/OS® systems interactively and in batch processing. ZDT is designed to deal with a large production data efficiently while protecting integrity and privacy. With ZDT, access to mainframe data is made simple by its intuitive and consistent user interface across a wide range of data stores available on the platform. ZDT advantages include the following: - Comprehensive support for a wide range of data store types: Data Sets (VSAM, QSAM, PDS, PDSE, AIM, OAM), DB2, IMS, WebSphere MQ, CICS and Hierarchical File System under UNIX System Services - Accessing and manipulating mainframe data without programming. - Manipulation interactively and in batch as well as RESTful APIs in conjunction with IBM® z/OS® Connect Enterprise Edition. - Usage of templates to represent logical view of mainframe binary data. Templates are typically created from COPYBOOKs and enable to represent most complex data structures found on the platform. - Knowledge retention of mainframe data by usage of the ZDT template repository. - Powerful set of productivity improvement features to assist ISPF users. In addition, we are announcing an add-on product called HCL ZDT APIs. This add-on product provides Java™ and Swift application programming interfaces (APIs) to manipulate mainframe data. APIs leverage ZDT’s template infrastructure to understand logical layout of mainframe binary data. Mainframe binary data is converted into JSON format and returned to API consumers in Java or Swift for easier interpretation and manipulation by developers with no mainframe background.
Usage scenario of ZDT APIs includes but not limited to the following scenarios: - Replacement of legacy applications for batch processing of data in Java. - Integration of traditional mainframe applications with new applications. - Interpretation of mainframe operational data for analytics (eg. SMF and RMF data). - Manipulation of mainframe data in virtual storage.

When logging on to the Analyzer to view software inventory and usage information, users must supply suitable credentials. Most commonly, the Analyzer is configured to use the system’s security product (such as RACF) for authentication, and in this case a valid user ID and password is the minimum information that must be supplied to effect the logon.
However, the traditional 8-character password is no longer viewed as being sufficiently secure by many organisations, and so security products like RACF have added support for password phrases which can be up to 100 characters long. However, the Analyzer would only transmit the first 8 characters of the password character string to the system when requesting user authentication by the security product.
PTF UA96765 has now introduced password phrase support to the TADz Analyzer. Whether the input is a password or a password phrase is governed purely by its length. Password input which does not exceed 8 characters in length is processed as a classic password, whereas input with a length in the 9- to 100-character range is processed as a password phrase. Because phrases can consist of mixed-case letters, numbers and special characters including blanks, passwords will no longer be folded to upper case. As a result, the Analyzer setting AUTH_UPPERCASE=Y now has no effect.
The TADz SCRT Import utility reads data created by the IBM Sub-Capacity Reporting Tool in the form of CSV files and imports it into the TADz Repository database. The Analyzer can then be used to query the database to examine trends in the SCRT data and to compare it with corresponding usage data.
With APAR OA55788 TADz has enhanced the SCRT Import utility to support Version 25 Release 1 of the IBM Sub-Capacity Reporting Tool. This version of the tool has Country Multiplex Pricing support which produces a report containing sections for each machine in a multiplex environment, and which TADz has not supported until this APAR. The SCRT Import utility now recognizes and interprets this report, importing data for all machines into the TADz Repository databases. Country Multiplex Pricing support provides additional information that TADz expects to be able to take advantage of in the future.
One of our key focus areas is modernization of mainframe assets. Specifically, we are focussing on enabling RESTful API access to mainframe data and green screen applications. Take a look at our overview presentation, “A new approach for modernizing and reusing mainframe assets”, and let us know your thoughts.
As part of this effort, we are taking advantage of the Continuous Delivery approach to incrementally deliver new functionality to you each quarter. Specifically, for File Manager for z/OS® product, we delivered two sets of significant enhancements in 1st half of this year. Please look at videos which provides a nice overview of its capabilities (https://www.youtube.com/playlist?list=PL2tETTrnR4wuMOkKyW_VqINanb2OipCyv).
Along with the product enhancements to enable generic and specific data access, the base product is enhanced to provide better overall experience (usage via APIs as well as usage of File Manager product interactively and batch). Specifically, we added support for better handling complex REDEFINE structures. You can read about this in this blog.
These enhancements are driven by your requirements. Looking ahead in the future, we have a plan to deliver additional enhancements over next several quarters. We will continue to report our progress here, however we would equally appreciate your feedback. Talk to us and let’s continue our Innovation journey.

The File Manager Service Provider for z/OS Connect works in conjunction with IBM’s z/OS Connect to facilitate REST API access to z data.
The latest version of the File Manager Service Provider for z/OS Connect has been released, with new function that allows you to build your own z/OS Connect SAR files that prescribe REST API responses that match your data. The File Manager Service Provider for z/OS Connect now supports two methods for accessing z data via REST APIs:
Generic File Manager provides a pre-built z/OS Connect SAR file for use with IBM’s z/OS Connect API Editor. APIs return a generic mapping of z data resources including MVS data sets, USS files, CICS (VSAM, TD, TS), and MQ queues. Using the generic method, you don’t need to create your own z/OS Connect SAR files for your APIS. The provided SAR file is a one-size-fits-all solution. Example response:
Alternatively, customers who want API responses that map specific data resources can now use the provided File Manager Build Toolkit plugin in conjunction with the z/OS Connect Build Toolkit utility (ZCONBT) to create SAR files. APIs associated with created SAR files return a specific mapping of z data per a given File Manager template or copybook. Example response:
File Manager has extended its Service Provider for z/OS Connect feature to support access to mainframe data via REST APIs using two access methods: one that returns data in a generic JSON format and another that returns data in a JSON format matching a File Manager template or copybook. Supported data types include MVS data sets, USS files, CICS (VSAM, TS, TD), and MQ queues.
File Manager templates have been enhanced to support redefines criteria for COBOL REDEFINES, PL/I UNION and equivalent constructs in Assembler. Redefines criteria can be specified for a field with a redefines clause or a field that is the target of the redefines clause to facilitate a more intelligent view of data where complex redefines are specified in the copybook definitions. It is especially useful for producing JSON formatted data. The idea is to ensure we are limiting display, JSON output, compare and copy processing to the relevant fields for a given record.
File Manager has added the enhanced change command which is like the enhanced search command with the addition of a replace feature. It includes the following:
Multiple change commands against multiple data sets.
ISPF change behaviour of absorbing blanks.
COBOL Usage National numeric support has been added for zoned and external floating point data items declared with USAGE IS NATIONAL.
