These are timings for a large one million customer records, dataset. It follows the same process below. It just goes to show my reasoning why I like this method to move large datasets to the virtual mainframe. Use maketape to create the virtual tape file! bill@bill-MS-7B79:~/Mystuff/Mainframe/MVS/JCL/TAPEDASD$ time ./maketape INPUT: customer-million.txt VOLSER: VOL001 DATASET: CUSTOMER.FILE OUTPUT: …

Move programs to github
Move updated parsejob (fix counts and don’t die if input missing) and toherc (don’t restrict tapes to tape directory) into github.
Rebuild Pi-hole
So maybe a week ago pi-hole stopped working. That’s not great reliability. A month of use before failure. At that time, I tried to SSH into it and it seemed sluggish to the point of being unusable. I didn’t know if it was hardware (did the pi overheat and components were failing?) or software. So …
Hercules virtual tape review
Previously, I talked about Hercules virtual tapes without being specific. I find this useful for getting large amounts of data to a MVS dataset. So here I find myself reviewing/documenting the procedures…again! These below examples are using test data with a fixed length of 165 characters! Getting the data It seems I created some fixed …
Linux Mint auto updates
I don’t like what I’ve been reading. Seems Mint is thinking of playing Big Brother and forcing updates on users. I keep my system updated but it’s my idea!
USB Mic issue – part 2
I seems that my Mint USB mic issue is with audacity! The mic works fine with OBS studio on Mint. As I said before it also works fine with audacity on Manjaro too!
I’m on a roll with problems (3270)
So I started MVS in hercules mainframe emulator on Manjaro. Went to start a x3270 terminal. It did not exist…no problem I’ll just install it. So I installed it. But it said it required a restart. Hardly anything requires a restart. Ok I need to try and shutdown MVS manually. Found manual said something like …
USB Mic issue
So the USB mic issue that I had on Linux Mint apparently is not an issue on Manjaro. I’m pretty sure I used it on Mint with no problems before. The problem is if I record a 10sec clip in audacity, it plays back in about as nano second. I deleted audacities setting folder with …
Large Manjaro update/So much to do
Over a GB with 227 updates. Looking at “uname -a” output doesn’t seem to be using a new kernal. Or is it? To do… Find out why. See above. Get Hugo to use relative addressing so I can move hugo static site to subfolder. See if I can use “Samson Q2U Recording and Podcasting Mic” …
Cursor highlight for videos
I see these highlighted cursors all the time on YouTube, but trying to find out how to do it wasn’t easy. It’s so easy to loose track of that mouse pointer in a video. Install some obscure package or some double talk answer. It seemed almost like it was some trade secret. After some digging. …
