Rocket Mainframe DevOps

As part of a code-signing initiative, I am working with SHA256 digests on z/OS.  In the past, I would download files to a Linux or Windows machine and verify that the hashes matched expected values. But for some reason, Rocket openssl (OpenSSL 1.1.1h 22 Sep 2020) yields different digest values (openssl dgst -sha256) than Linux or WIndows. The only way to get the same hash is to tag the file  on z/OS before creating the hash: chtag -tc ISO8859-1 <filename> This feels really odd, since the original file is binary.  Is this working as designed? ------------------------------Jeff MierzejewskiAdvisory Software EngineerIBM Global ServicesAustin TX US------------------------------

Status: DeliveredBy default, we will take the previous version after another checkout of a component. It would be helpful if this frequent process could be done in one workstep.If a component during its modification was changed at the baseline, the new baseline version of the component must be taken over again in the package via checkout. Afterwards the developer will check the last modification version against the new baseline version.   Our standard process is, the previous version is reactivated in the package after the checkout.   Because we process a large amount of components in this way, it would be helpful for us to be able to do this in one work step (checkout and reaktivating the last modification version).

I try to read a sequential dataset (FB LRECL(1000)) by using this simple code:# ================================================== count = 0 thefilepath = "//'sa8sb22.resultfb'" count = len(open(thefilepath, 'r', encoding="cp500").readlines( )) print("There are ", count , " lines in the file") # ================================================== I have 133 records in the file, but the above code delivers 1 (one). I suppose, no read is executed.I suppose it is realted to the encoding, but I don't find any better as the cp500.The file is definitive EBCDIC (x'81' for 'a').Any hints pls.?------------------------------Gabor MarkonMainframe ArchitectSelf RegisteredBudapest HU------------------------------

We are currently using a git protocol helper to allow us (in ZMF R&D) to synchronize off platform development, managed by git in a local repo, with the overarching control provided by ChangeMan ZMF. The target ZMF package is presented as remote repo to local git by using a ‘url’ of  ZMF://<target ZMF profile>/<target ZMF package>   For example, we use:   ZMF://PRODZMF/CZMF125     to address package CZMF000125 in our production ZMF subsystem.   We can then use clone, pull/fetch and push  to synchronize change between the local repo and the ZMF package.  The ZMF package is the ‘gold code’. We have put in place local regression checking as part of this support and the git merge process can be used when refreshing the latest code from the ZMF package into the local repo. The protocol helper relies on the use of our zowe zmf cli plugin to communicate with the target ZMF. The zowe zmf cli takes care of managing the ip add

We keep seeing emails that there is a HOTFIX for Log4j Security Issue.  If so, do we have to request the hotfix?#ChangeManZMF

Rocket has moved to a new system – conda – for downloading, installing, and upgrading all z/OS open source ports developed by Rocket.  With conda, a single command can replace dozens of steps and commands previously required to install some open source products.  For example, installing z/OS Git with its dependencies formerly required over thirty steps but now can be accomplished with a single conda command. Conda is an open source tool ideally suited for delivery and deployment of software on the mainframe due to its channel concept and multiple types of channels supporting varying degrees of security including file channels for air-gapped systems. Rocket has set up two internet channels from which you can download z/OS open source ports using conda – one public and open to all, the other a secure channel server on premise at Rocket available only to Rocket customers on a support plan. z/OS Miniconda is a free bundle of open source containing everything you need to run conda on z/OS.

As the Apache Log4j vulnerability (CVE-2021-44228) was disclosed on Dec 09, 2021, your Rocket Open Systems Software for Z (ZOSS) teams have been actively monitoring the issue and assessing its impact on these products.  It has been determined that our ported tools do not contain a version of Log4j that is impacted by the vulnerability. Please feel free to reach out to support or product management should you have any questions or concerns regarding any of the open systems ports for z/OS and the Apache Log4j security vulnerability. ------------------------------Jeff CherringtonVice President, Product Management, Z SystemsRocket Software------------------------------

Hi everyone,I am on git version 2.14.4_zos_b09 under USS. When I try to issue git commit without parameters I am getting unreadable text in vi. I guess it happens because it shows me the text in iso8859-1. Can it be switched it to use ibm-1047?

Most organizations understand the value of modernizing mainframe application build and test processes, but bridging the open-source vs. traditional mainframe knowledge gap is often a barrier. This example entirely made up of open-source software may help get you started. @Tatiana Balaburkina and @Vladimir Kudriakov recently shared this demo at the Linux Foundation's Open Mainframe Summit, showing an open-source DevOps toolchain driven by Jenkins. The source code, scripts and metadata files used to build this sample application are included.  The 12 minute video demonstrates the toolchain in operation.Let us know what you think and what questions you have below, and do share your approach with the community if you have an existing solution that works for you.

Hi,I installed Bash over the free conda channel (version Bash 4.3.48). This version seems to have a problem with its terminal config.The bash version don't read the TERM env correctly.For example:$> export TERM=xterm$> export TERMINFO=/usr/share/lib/terminfo$> echo $TERMxterm$> clear'/u/userid': unknown terminal type.echo $TERMxtermI would guess this bash version reads the homedir env instead of term.Rolling back to the previous Version  fixes the problem.Kind regards,Björn------------------------------Björn SchanzSysprogR + V Allgemeine Versicherung AGWiesbaden Germany------------------------------

Hello, I am looking to use Python on our mainframe. In my search I have come across two versions: Rocket Software's Python (<= 3.7) IBM Open Enterprise Python (>= 3.8) Now, apart from the versions offered, it is not clear to me if there are any significant differences between these two.Is Rocket Software still developing their version? Or did they halt active development because IBM released theirs?I hope somebody can give me some insight into this matter.Kind regards,Glenn#Python

Hi,I've been an occasional user to this site over the years whereby I download/install open source USS tools for our z/OS systems. It's probably a couple of years since last time, so I am now trying to get going with the new Microconda method of download/install.  I'm having trouble configuring access to the Rocket conda server:-Configure to use Rocket's secure conda server?

I am trashing all of my current miniconda efforts and hoping the old ways still work.Too much 'assumed' lnowledge from the Linux world (bash shell for example) is not in my 30 year z/OS history.  I can stumble around basic commands and super simple scripts, but this miniconda thing is a monster.   I did manage to get miniconda under my $HOME directory and it can query the public channel web site.Creating local environments and attempting to install actual open source (like Perl) failes spectacularly.what the heck is a .so file and why didn't it create them when I defined a new environment?  ../.ffi/*.so files not available or found.How do you select where to install the open source.  At the end of the day what would end up in my General User $PATH variable.I was trying to update my Open software (last done in 2015).   But this way is just not going to cut it.    It all looks simple in the pdf downloaded instructions until it cheaps out with a web link to a conda website for how to lear

Status: DeliveredIncluded in ZMF 8.3Hej ! In our site, we use CMNVPOOL variables at various stages of a package, created  auto-mechanisms that are triggered by the variables, Etc..  At the moment, to maintain the variables it has to be done only within the HLLX environment. I am wondering if we can have a PGM utility, which we can execute via BATCH to Delete, Put, or even Define variables directly into the CMNVPOOL. What do you reckon ? /Flint#CMNVPOOL#HLLX#ZMF
