John, You can use the SVCUPDTE macro in an assembler program to update the SVC table dynamically after you first load the module into CSA using a call to IEWFETCH. The SVCUPDTE macro was

I'd be really interested in seeing what that job looks like, or a hint as to what utilities and processing were involved. Sounds like a lot can be learned there.

Alejandro, One of the beauties of running Hercules – is we have so many options You might consider simply making a copy of the Hercules disk files – on your PC – (this would require the system

Hello Mark, yes, I've managed to convince myself of that by playing around with some code and and user SVCs of my own. I managed to force an FFF abend in my own code when trying to invoke user SVC

I use the tape robot perl script from the files section (tape-robot-automount-herc.tar.gz </g/H390-MVS/files/tape-robot-automount-herc.tar.gz>) and have been for years. It basically

Hi folks! I'm working on backing up stuff. Manually getting stuff out of MVS to keep a copy is not hard... however, as a sys admin, I'm very much used to the idea of sceduled backups. After reading

Thanks Greg, I strongly suspect that you're right; which leads me a question.... I had a look at the sysgen for TK4- and I see that a range of user SVC numbers are defined, that is a range 201-248

Remember, for a non-VSAM dataset you don't even have to catalog it. Khalid

It worked!!! I had initially a problem cataloging the target dataset because Of the overll JOBCAT DD ... So I had to just use STEPCAT DD on the REPRO step, and catalog the dataset on a final

Hi! I though on the idea of big PDS with data being added to members...? but I though it had to have its cons (sure... I always trip some wire :-P) ... I definitely have to learn how o plan for such

Alejandro BABY STEPS – you are certainly getting some good OJT – while I recognize – this is frustrating – NOT TRUE my friend… now, for you to use a HLQ that catalogs back into the same

Hi! By one side... I was missing the JOBCAT / STEPCAT DD component on all my tests...?Now I understand why they didn't work :-) But on the other side, I've also found that, apparently, dumping to a

I took good notice of that JOBCAt / STEPCAT stuff!!! Cheers.

If you can't figure out the catalog reorg, then create another volume, define a catalog with CYL(10 10),NOIMBED NOREPLICATE a different name, HLQ. Copy datasets over to the new volume and update JCL

Here is a sample job, notice the STEPCAT statement, it may help you, or as has been suggested put the full UCAT filename on the REPRO statement //REPROUC1 JOB 'JAY

Alejandro Ok – for your REPRO You can specify EITHER – of two formats – (or a mix) One method – you specify a DD name that you reference in your control statement The OTHER – you simply

Hi Folks. I've a UserCatalog (UCUSRDT0) on a volume (USRDT0) for my user/users (ALEX) in a Tk5 install ...so far, so good, until the catalog needed a reorg due to CI splits. I've been reading some

Jeff and Patrik, You have no idea how much pleasure I receive in seeing these networking configurations, and per your responses WORKING! My first IT job involved networking before networking as we

You should definitely use shadow files. I've been using them since starting with Hercules in 2009, and I can't count the number of times they've saved my ass when making changes to my z/OS 1.10
