With the Holidays and the New Year approaching, the DFSMS team wanted to provide a wrap up of everything we were excited to announce and bring to you this year!
Thank you to the entire z/OS DFSMS team for collaborating and working diligently to provide these items and we are excited to do it all again next year!!
- EzNoSQL enhancements:
- Support has been added to scan NoSQL documents sequentially using a new ordered index parameter on the C and Java EzNoSQL create APIs.Check out the blog post we put out for this enhancement here!
- Enhancements to EzNoSQL APIs allow applications to now utilize Python on z/OS, in addition to C or Java, to build modern, scalable NoSQL database applications. Python offers a low-entry barrier for experienced and new developers alike due to the simplicity and intuitive syntax. Check back for blog posts in 2025 for more content around the EzNoSQL Python APIs!
- Check out the EzNoSQL Content Solution Page for more information and how to get started
- Cloud Data Access (CDA) enhancements:
- The ability for z/OS applications to target Microsoft Azure Blob Storage and File Service objects is now available on z/OS V2.5 and above.
o Uploads of data to Amazon Simple Storage Service (S3) cloud providers can have the data protected by signing the payload.
o Our CDA Owner, Andrew Wilt, and CDA team have created a blog series covering all of the CDA enhancements we made this year!
- DFSMShsm Enhancements:
- Incremental UNIX file backup -- A new option, -i, has been added to the Java hbackup command to allow clients to specify which DFSMShsm host in a multiple address space HSM (MASH) environment to direct the request to. This enables clients to distribute the workload among multiple DFSMShsm hosts.
- Multiple endpoints for TCT TS7700 DFSMShsm enhancements provide the ability to configure multiple endpoints for both production and disaster recovery regions that will automatically fail over to one or more of the configured endpoints in the event of network outages.
· z/OS DFSMS enhancements:
o z/OS data set encryption delivers a usability enhancement to allow users to request that the system convert a newly allocated encrypted data set to non-encryption during the first open of an encrypted extended format, basic format, or large format data set when an encryption restriction is detected and instead convert the data set to be a non-encrypted data set in order to avoid any application outage due to an open abend based on the restriction.
- Data Set File System enhancements:
- Support has been added to enhance the capabilities of the new data set file system by representing data set characteristics as extended attributes. Additional enhancements allow z/OS UNIX users direct access to their jobs on the JES spool. IBM has also provided support to allow users to handle migrated data sets.
- zFS Health Check and Conversion utility:
- We have provided two zFS health checks that allow system programmers and storage administrators the ability to optimally tune their z/OS UNIX file system and to configure them to prevent outages and failures. In addition, a new conversion utility is being provided to help customers migrate their zFS directories from v4 to v5, which provides better performance characteristics.
- TLS 1.3 Support for Transparent Cloud Tiering (TCT):
- Enhancements enable TCT users to specify the latest TLS version 1.3, and ensure data transferred to cloud object storage utilizes the fastest and most secure TLS handshake available.
We would love to hear your thoughts on all of our DFSMS solutions and these new enhancements! Leave a comment on this blog post, start a discussion on the DFSMS Community Page, or join Mainframe Data Management LinkedIn group to discuss there!
