Rocket Mainframe DevOps

ZMF Explorer no longer available in the marketplace? What should we communicate to our developers?

Yesterday we upgraded to ChangeMan ZMF 8.3.2 and today we get this error when we check in a component from VS Code:  Content error: Record Length(493) exceeds Maximum(80)I checked to make sure I have the correct zmfrest war file.

VS code updated to latest version and zmf explorer profiles disappears.vs code version 1.124.2 ZMF explorer 2.0.10I tried deleting zowe.config.json, zowe.schema.json, and extenders.json.   Restored backup of zowe.config.json and zowe.schema.json.I uninstalled zmf explorer and re-installed it.    I installed a previous version of visual studio code. Unfortunately, VS code auto updated.None of these corrected the issue.  

I have updated the file associations in the ibm open editor extension.   We have two custom  types which mapping incorrectly on the local folders.J01 becomes a suffix of JAVAP01 becomes a suffix of TXTHow can I correct this file mapping/associations?

 I have encountered an issue while working with a component in my cloned package in VS Code. I recently made some changes to this component, and my colleague made other changes to the same component. As a result, I ran into a merge conflict when attempting to push my updates.After carefully resolving the merge conflict and committing the changes, I tried to push back to the mainframe. However, I received an error, and I am not sure where the problem lies. I have double checked to ensure there are no non-mainframe compatible characters in both the merged source and my commit message.Could someone please advise if there is something I am missing in the process, or if there could potentially be a bug in the git connector? Any guidance or troubleshooting tips would be greatly appreciated as I would like to get this resolved as soon as possible. 

Hi everyone,I’m working on a small internal workflow and wanted to ask for advice from people using Rocket Open-Source Languages and Tools for z/OS.We have a process where project metadata is exported from a workstation and then transferred to z/OS USS for validation and reporting. The files are mostly CSV and JSON, and they include fields such as project ID, file name, export date, duration, owner, and status. Some of the source files are created after media work is completed in a pc video editor, but the actual task on z/OS is only to validate and process the metadata, not the media files themselves.I’m planning to use Python on z/OS USS to: Read the uploaded CSV/JSON metadata files Validate required fields Normalize date and filename values Write a clean output file for downstream reporting Log any rejected records with a reason My questions are: Are there any z/OS USS file encoding issues I should watch for when reading CSV or JSON files created on distributed systems? Is

HelloWe have a strange issue on our VDIs with the Git connectorWe are still struggling to get the installation right. When we try to perform eg a git clone we ar getting a connection problem. We have setup the server using https, everything we do from the VDIthe zmfrest application the ZMF Explorerall works fine, except the git commandsI changed the server back to http and adapted the zowe config json to use http and then the git commands worked fineHowever other colleagues installed GIT_CLI and GitBash and then the git connector commands using https worked fineCan anybody shed some light on this, what am I missing on the pre requisites of the Git connector, hereby some (probably stupid) questionsdoes the Git connector need Git to be installed on the VDI if the ZMF Explorer uses https, why would the Git connector failAny feedback is welcomeBest regardsJohan

Recently we were notified that our systems team is planning to upgrade to z/OS 3.2.  We are currently on ChangeMan ZMF 8.3.  Due to resources we will not have time to upgrade before they plan on upgrading z/OS in August 2026.  I know 8.3 has not been tested and it is recommended to go to 8.3.1 but I am curious has anyone taken the chance and upgraded z/OS to 3.2 while still on 8.3?  If so, have you encountered any issues?  

Hi,We are currently running ChangeMan version 8.3.0 and are planning to upgrade our z/OS environment from version 2.5 to version 3.2.Could you please confirm whether ChangeMan V8.3.0 is compatible with z/OS 3.2?Additionally, if anyone has experience running ChangeMan V8.3.0 on z/OS 3.2, I would appreciate your guidance. Specifically, it would be helpful to understand any challenges encountered following the z/OS 3.2 upgrade and to know if any patches or updates are required for ChangeMan V8.3.0.Thank you in advance for your support.Best regards,Karthick

Occasionally, VSCode fails to correctly load extensions. When you then attempt to click on a ZMF Explorer icon you may get a message for example. "Refresh Command not found" etc This may sometimes occur when VSCode has performed one of its regular monthly updates. When this occurs: Shutdown VSCode,  Restart VSCode Click Help - Toggle Developer Tools  Then select Console from the top line menu barAttempt to open and run the extension.Check the console for errors. Often that can provide a good indication of what actually went wrong.#HowTo-BestPractice#ChangeManZMF

It would be nice if you could have a package filter in the favorite without having to drill down to packages under an application.

Hi ,  since January (2026) we started the preparation to implement Changeman ZMF 8.3.1.  Investigation was ongoing. By accident , when checking some info on your website mid February , we discovered that since February 10 th (2026)  version 8.3.2 is available.   Since we discovered this by accident , we were surprised.Is there a way we can be informed when a new version is available ?  (We are already subscribed to newsletters)Or is no communication done on this topic ?

Hi,The version of cURL in my z/OS system is: curl 7.52.1 (i370-ibm-openedition)curl-config --ca returns: /u/mvsbuild/py361z/python36/etc/ssl/cacert.pem But I can't find that directory. Instead I found cacert.pem is under /u/python/python36/etc/ssl. So I created that directory and copy cacert.pem there.I tried 3 different ways:1) When I issue the command without specifying --cacert and --capath, I got errorcurl: (60) SSL certificate problem: self signed certificate in certificate chain2) When I issue the command specifying --cacert and --capath, I got errorcurl: (77) error setting certificate verify locations:CAfile: cacert.pem CApath: /u/mvsbuild/py361z/python36/etc/ssl 3) When I copy the cacert.pem file to the current directory, it works.Questions:1. Is there something wrong with the build process that made the cacert.pem stored in a wrong location?2. After manually copied the cacert.pem to the desired location, why can't it be used, even specifying the location explicitly?3. Is it a

Hi, we're actually running ChangeMan ZMF 8.3.0 and we're planning ChangeMan activities for next year. I've seen that ChangeMan 8.3.2 should be out in 2026 Q1 so I was searching informations about this version. Is there already a list of fixes and enhancements planned for 8.3.2? I would like also to ask where is the link for the ChangeMan ZMF versions / EOS dates matrix. Thank you. ------------------------------Stefano AntoniazziRaiffeisen Information Service------------------------------
