MTS d6.0A crashes on Hercules 4.5


 

开云体育

Anyone using Hercules 4.5 yet?

?

When I run the standard distribution (i.e the Hercules.cnf file that was provided with d6.0A), the system appears to crash whenever it requests that the stats tape be mounted.

?

All session freeze, the console goes blank except for a request to mount the DUMP tape.

?

Many of us are.

But not very many of us are running MTS of course!

THAT'S not good. :(

Mount the dump tape? Is that an MTS thing? Or are you maybe referring to the message that Hercules itself issues whenever it crashes?

IN ANY CASE, please goto:



and create a new GitHub Issue for this problem. PLEASE try to provide as much detailed information as possible, including your COMPLETE Hercules configuration file as well as your COMPLETE Hercules logfile. Also helpful would be the specific version of the guest operating system you are using (which I presume is MTS d6.0A? Yes? Where can it be downloaded from? Thanks) and whatever logfile it might provide.

Also helpful would be your configure/make log if you built Hercules yourself. Basically anything you can think of that might be helpful in recreating/troubleshooting the problem. The more detailed information the better.

Thanks.

This sounds like a "super dump" which is the MTS equivalent of a kernel panic. There may be some incompatibility between that version of Hercules and D6 MTS.

If you can figure out how to create a labeled tape (either in MTS or elsewhere) you can get a superdump and send it to me. If it's something simple I might be able to figure out the immediate cause of the crash. The dump tape needs to be a tape with standard IBM labels. The volume name should be "DUMPnn" where "nn" is any two characters, normally digits. The tape file may be large so it would be best to ZIP it or put it on a shared folder like Dropbox.

Or, assuming it's a program interrupt of some sort, you could use the tools built in to Hercules to see what it is. This might give us a hint.

I'm not really promising anything, some super dumps are difficult to figure out and I can't put too much time into this.

Which is precisely why I asked to see his Hercules logfile.

AND his configuration file.

AND where he downloaded his guest from, instructions for how to reproduce/recreate the problem, etc...

Basically all the standard things we ask for as documented in our "SUBMITTING PROBLEM REPORTS" document:

*

Providing such information will allow us to tell whether the problem is a Hercules bug or an MTS bug.

And the FIRST step is always creating a GitHub Issue for the problem, proving as much *detailed* information as possible (as documented in the URL above).

I can run MTS 6.0A fine with SDL Hercules 4.5.0.10830-SDL-g58578601 on my iMac (check it out on the attached log file). However, I don't face a problem with the stats tape, so I don't know what would happen in that case.
