Computer problems – Pt. 2

So in order to proactive about my HD failure, I bought a 2TB drive to replace the suspected 1 TB failing drive. However when attempting to create partitions on and formatting the new HD by reinstalling Manjaro, I got “The installer failed to create partition on disk…”. I found a boot-able gParted DVD and thinking it is probably more powerful that the one in the installer. gave it a try, but it failed also. Thought about it for a while then removed a 160GB drive and moved new drive there and it worked fine. Meaning the old 1TB drive was probably OK, and it turned out it was.

So barring a cable problem it also means the SATA HD connector or more likely underlying controller (I’m assuming this) on the motherboard is bad. That leaves one next to the Blu-ray connection. Don’t really remember but it seems like there is some issue concerning placement of the Blu-ray so I’m not sure I can use the SATA connector next to the Blu-ray for a HD. But it’s worth a try. Seriously considering removing the Blu-ray anyway, it hasn’t worked well since I got it.

All this is a reminder that I need readily accessible recovery media…probably on USB drives.

Computer problems…me thinks!

Disk to be specific. Shutdown problem last night, didn’t shutdown cleanly. Suspected it, hoped it would come up this morning…it did! This disk command was first thing I ran at startup. Of the 4 disks this is the only one reporting bad sectors…of course it holds all my home directories.

Copy a PDS to another PDS

Thinking about this new YouTube Video and thought maybe it would be more useful to others to do it on a 3270 using ISPF. Which I assumed would be intutitive…but it wasn’t. See the copy utility below. It wasn’t clear to me how to copy looking at this panel,from the beginning, after I decided I should enter the dataset name where I did, I was looking for a different place to enter the member name. Finally I did decide to enter it like I did below. But I still had problems, because I wasn’t using single quotes, as shown below, in the data set name. There were no spaces, so why should I? I had to google for that little tidbit. I don’t use single quotes in the DSLIST utility!

Anywho, it would have been quicker for me to do everything on my Local host by submitting JCL. This is what I mean about learning more myself by digging for information to explain things to others.

My YouTube videos

I’m not a put myself out there kinda guy. Also since I tend to have a lot of sinus problems, my already pretty bad speaking voice is even worse by my sniffing and throat clearing. But I want to make another YouTube video. These are Hercules MVS (Tk4-) vids. I have no desire to be a content creator in that space. The Moshix Mainframe channel already has that covered, and very well I must say. I’m basically making them for myself, but if others wondered about the things I do, then maybe they would be of interest to them too. These are topics that I looked for information on but either didn’t find it covered, or wasn’t covered sufficiently for my purpose. If I had this video on Virtual Tapes when I was looking for a way to get a lot, keyword a lot, of data to MVS/Hercules…it would have saved me a lot of time. I posted this video on March 31st and don’t think it has any views. But since I’m not trying to be a prolific content maker, it doesn’t matter that much. Besides making the video as if others might be interested, causes me to perhaps do a better job than if it was only for myself. I find myself digging for info a little harder, researching a little more, than I might otherwise. So it really is good for my own learning.

I don’t have a list of things I want to cover. However in the post I’m talking about on Virtual tapes, I made a statement that made me want to post another video showing a solution to something I brought up. I’ve already prepared steps then redefined those steps to make them better and clearer. I’m only waiting for my sinuses to improve!

As a side note, making these videos gets me more comfortable with OBS Studio and Kdenlive, my open source solutions, because I’m a Linux only disciple. I’m only scratching the surface of the capabilities of these programs.

Manjaro – No 3270 emulator

Tried to install x3270 today…and it doesn’t exist in their repositories anymore! As a matter of fact, no 3270 emulator could be found. I thought Arch had everything? Maybe the writing was on the wall, the last time I installed it on Manjaro recently, it was in a foreign language! No love for mainframes? Just considered a dinosaur? Well maybe it’s time to change my backup distro from Manjaro. It’s a big enough issue for me to change. And no I don’t want to install from source.

It’s ironic that now they chose to remove the 3270 emulators at a time when mainframes are perhaps the most popular they’ve been in a long time! Maybe a few years ago you could have used the long standing argument that the mainframe is dead, a dinosaur and obsolete. But have you googled mainframe or COBOL in the last year?

You know which Linux distro still thinks mainframes are important? Uh, the one who IBM bought…Redhat! So that would actually be Fedora in my case! I’ve been hearing a lot of good stuff about Fedora in general lately. I think the last time I used Fedora it was version 5, as of today it’s on version 33. OpenSuse may also be an option, if I want to stick with KDE.

Done with Pi-hole…for now!

Love the concept. First time I installed it seemed to work great! A month later the server ran like molasses just trying to log in. Second time installed didn’t work as well. Queries reported (or whatever it’s called) seemed to be updating but blocked report numbers were very low, even though it appeared to be working. Today all sign’s of activity are zero. Tried to update Pi-hole itself but failed. Failed with what? I don’t know but I can’t be “fixing” the damn thing every month. It needs to run like an appliance. I don’t want to be a Pi-hole administrator. Maybe try it again at a later time.

Compile, link then execute

I have been using compile/go JCL to run my COBOL MVS programs, since that was the JCL I found used for other things. Since I mentioned in a video that the execution speed of a JOB was not a true indication of speed, because in addition to the execution, the program was compiled every time. I figured it was time I looked into doing it the long way. If you worked at a company you wouldn’t recompile a “production” program every time you wanted to run it! Programmers testing their programs, may want to recompile until it’s working properly! In looking at this, because I am very rusty…I had questions about where various files were stored. Well as far as I can tell they just need to be stored in a PDS, I thought perhaps the object needed to be stored in a special library, but apparently not. I just created a normal PDS and pointed the linkage editor to it. Then told a different JOB, where it was, using a JOBLIB card like…”//JOBLIB DD DSNAME=WHB.STUFF.PDS,DISP=SHR”. I guess I could have used a STEPLIB also!
