Installing Z Vm On Hercules

Installing Z Vm On Hercules

Hercules 4.0 (Hyperion)You will need to amend the configuration file hercules.cnf to reflect your device layout and intended mode of operation (S/370, ESA/390, or z/Architecture). See the Hercules Configuration File page for a complete description. How to run Debian under Hercules would definitely be on-topic here, since Hercules is a software emulation of the hardware on which Debian for s390x was designed to run. If your question regards how to run Debian in a virtual machine under z/VM, that would also be on topic. But questions about how to run z/VM under Hercules are not on topic. You will need to amend the configuration file hercules.cnf to reflect your device layout and intended mode of operation (S/370, ESA/390, or z/Architecture). See the Hercules Configuration File page for a complete description. The Hercules mainframe emulator is a mainframe in software, and it runs all IBM mainframe operating systems, such as OS/360, OS/390, the z/OS family, and mainframe Linux. If you want to try out OS/390 or the current z/OS releases, good luck, because they have restrictive licenses that.
 This is official web page for Hercules version 4.0, working titled 'Hyperion', the development version of Hercules. Hyperion is developed and supported by a small group of volunteers.
Hercules is an open source software implementation of the mainframe System/370 and ESA/390 architectures, in addition to the latest 64-bit z/Architecture. Hercules runs under Linux, Windows, Solaris, FreeBSD, and macOS. Hercules is licensed under the terms of the Q Public Licence. The Q Public License is certified as an open source license by the Open Software Initiative.
Using Hercules to Emulate a MainframeTo emulate a mainframe using Hercules, you will need a few things:
A suitable host computer.
Hercules Installation and Setup Instructions
Mainframe software, most often an operating system.
Documentation for the software you plan to use.
 Prior experience programming or supporting a mainframe operating operating system is not required but is very helpful. 
Host Computer Capability Hercules will run just fine on most modern desktop or laptop computers. Performance will depend on what you do with Hercules. Emulating a mainframe running DOS/360, one of IBM's oldest mainframe operating systems and one that would run in 16KiB of mainframe core memory, will require far fewer host system resources than, say, a more modern MVS 3.8j configured with 16MiB of emulated core and running a number of batch jobs. One of the mainframe ports of Linux will require still more resources. 
 On x86-based systems, Hercules will work on 32-bit and 64-bit systems. Hercules does not require hardware-based virtualization capabilities and runs fine on operating systems that are themselves running in a virtual environment such as Oracle Virtualbox. 
 Muliple cores on the host system are helpful when emulating a mainframe configured with multiple CPUs, but multiple cores are not a requirement. 
Suitable Host platformsWindows: Windows XP x64 or Windows Server 2003 R2 or greater. Windows Vista or newer 32-bit or 64-bit will work. 
UNIX-like systems: Linux-based systems and FreeBSD. Solaris is supported when you build Hercules from source using CMake. 
macOS: Limited testing; feedback encouraged. 
 The above list is limited by the systems available to developers; we cannot afford to have one of everything. That said, we welcome feedback and issues from people who try to install on other platforms. One Hercules developer has installed on an emulated Raspberry Pi using QEMU.

Hercules Installation and Setup Instructions Select the installation procedure appropriate for your system.
Building Hercules for Windows Systems (Recommended). Uses CMake to build from source. 
Building Hercules for UNIX-like Systems (Recommended). Uses CMake to build from source. 
Hercules Installation for macOS Systems (Recommended). Uses CMake to build from source. 
Installation Using Legacy Tools. Uses makefile.bat/NMake (Windows) or GNU Autotools (UNIX-like systems and macOS) to build from source. Includes Windows binaries installation instructions. Useful if you encounter problems using CMake to build from source. 
 Most of the mainframe system web sites below include configuration instructions, sample configuration files, and in some cases, pre-built emulated DASD files. Some do not. The following links can be used to complete the setup of a Hercules emulated mainframe system. 
Configuration File. Create a configuration file that defines the system configuration including I/O devices. 
Creating DASD. Create emulated DASD volumes for attachment to an emulated mainframe. 
Compressed DASD Emulation. Create emulated DASD volumes using compression to reduce host computer disk space needs. 
Telnet/tn3270 Console How-To. Connect to an emulated mainframe 3270 device, 3270 operator console, and/or 1052 or 3215 printer-keyboard. 
Operating Procedures. Hercules command line parameters, panel commands, keyboard use, and the Hercules Automatic Operator (HAO). 
Mainframe Software You have a number of choices, and you are not limited to the packages listed here. IBM DOS/VS and IBM DOS/360 pre-date and bear absolutely no resemblance to PC-DOS or MS-DOS.
 Note that if you run mainframe software within Hercules, you must respect the terms and conditions of the software license for that software. 
IBM MVS. Jay Moseley has a very complete tutorial for installing and running MVS 3.8j, IBM's last release of MVS. 
Turnkey MVS systems. There are at least two. Each includes its own copy of Hercules. If a Turnkey system suits you, with its pre-installed mainframe operating system, there is no need to install Hercules from this site. Volker Bandke's MVS Tur(n)key System
Jürgen Winkelmann's TK4-
IBM OS/360 MVT, a non-virtual storage operating system. Jay Maynard has a good installation procedure at Introduction to Generating and Running OS/360 on Hercules
IBM DOS/VS. See Yahoo user ceo1944's 2314DOS.zip. This link downloads a zip archive of JCL and instructions from the Yahoo group H390-DOS/VS; free registration required. 
IBM DOS/360. There are at least four installation procedures available. The first three are in the H390-DOS/VS Yahoo group (free registration required) and the fourth is a stand-alone web site.  Bill Carlborg's DOS360-2314.zip (downloads a .zip archive). 
 Ben Huntsman's DYI-DOS360.zip (downloads a .zip archive). 
 Kevin Leonard's DOS-360 26.2
 https://sites.google.com/site/dos360install/. This site is loosely modeled on Jay Moseley's MVS 3.8j site noted above. 
IBM VM/370. See the VM/370 R6, page on the cbttape.org site. Turnkey versions of VM/370 are available on David Wade's G4UGM's Vintage and Classic Computer pages
Linux. Mainframe versions exist for the following. Some of these are not open source, and installation generally requires configuration of a mainframe Channel-to-Channel adapter to enable network connectivity for installation and/or post-install security updates. Debian Download a s390x CD or DVD. 
Fedora. Scroll down the page until you reach 's390x Architecture' at the bottom of the page. 
Gentoo. The s390x is included under '(experimental)' for 'Experimental architectures'. You know what that means. 
Red Hat. Paid license or 30-day trial only. Red Hat supports Fedora as its open source alternative. 
SUSE Enterprise Server. Paid license or 60-day trial only. 
Michigan Terminal System (MTS). The Michigan Terminal System Archive includes a turnkey distribution that has been tailored for use with Hercules. Additional helpful information may be found at https://try-mts.com/why-try-mts/
SATK. Harold Grovesteen's Stand Alone Tool Kit offers a collection of tools for creating mainframe assembly language programs on your computer for later execution within Hercules. The binary floating point test programs and scripts were created using SATK and serve as examples for the assembler's capabilities and use. 
TXXOS. Tommy Sprinkle's 'Bare Metal Programming for the IBM 370 Mainframe' web site walks you step-by-step from IPL'ing a simple listing program through building a disk-resident operating system. 
 See Frequently Asked Questions, starting with question 2.01 Can it run z/OS, z/VM, z/VSE? for more details on available operating systems and licensing matters. 
Mainframe Software DocumentationInstalling Z Vm On Hercules Tv Documentation for the Linux distributions, the Michigan Terminal System, SATK, and TXXOS may be found on their respective web sites. 
 Documentation for the IBM operating systems is a different matter; much of it was published before the Internet existed. The Bitsavers site and its mirrors contain a repository of scanned, and in some cases, OCR'd, IBM hardware and software reference manuals. The DOS360Install site has a couple of essential DOS/360 manuals that are not on Bitsavers. 
 Bitsavers is organized first by manufacturer, then by machine. Within machine one can find operating system documentation. Use the following shortcuts to the Bitsavers site. And explore...one can find very useful information in unexpected places on Bitsavers.

 Muliple cores on the host system are helpful when emulating a mainframe configured with multiple CPUs, but multiple cores are not a requirement. 
Suitable Host platformsWindows: Windows XP x64 or Windows Server 2003 R2 or greater. Windows Vista or newer 32-bit or 64-bit will work. 
UNIX-like systems: Linux-based systems and FreeBSD. Solaris is supported when you build Hercules from source using CMake. 
macOS: Limited testing; feedback encouraged. 
 The above list is limited by the systems available to developers; we cannot afford to have one of everything. That said, we welcome feedback and issues from people who try to install on other platforms. One Hercules developer has installed on an emulated Raspberry Pi using QEMU.
Hercules Installation and Setup Instructions Select the installation procedure appropriate for your system.
Building Hercules for Windows Systems (Recommended). Uses CMake to build from source. 
Building Hercules for UNIX-like Systems (Recommended). Uses CMake to build from source. 
Hercules Installation for macOS Systems (Recommended). Uses CMake to build from source. 
Installation Using Legacy Tools. Uses makefile.bat/NMake (Windows) or GNU Autotools (UNIX-like systems and macOS) to build from source. Includes Windows binaries installation instructions. Useful if you encounter problems using CMake to build from source. 
 Most of the mainframe system web sites below include configuration instructions, sample configuration files, and in some cases, pre-built emulated DASD files. Some do not. The following links can be used to complete the setup of a Hercules emulated mainframe system. 
Configuration File. Create a configuration file that defines the system configuration including I/O devices. 
Creating DASD. Create emulated DASD volumes for attachment to an emulated mainframe. 
Compressed DASD Emulation. Create emulated DASD volumes using compression to reduce host computer disk space needs. 
Telnet/tn3270 Console How-To. Connect to an emulated mainframe 3270 device, 3270 operator console, and/or 1052 or 3215 printer-keyboard. 
Operating Procedures. Hercules command line parameters, panel commands, keyboard use, and the Hercules Automatic Operator (HAO). 
Mainframe Software You have a number of choices, and you are not limited to the packages listed here. IBM DOS/VS and IBM DOS/360 pre-date and bear absolutely no resemblance to PC-DOS or MS-DOS.
 Note that if you run mainframe software within Hercules, you must respect the terms and conditions of the software license for that software. 
IBM MVS. Jay Moseley has a very complete tutorial for installing and running MVS 3.8j, IBM's last release of MVS. 
Turnkey MVS systems. There are at least two. Each includes its own copy of Hercules. If a Turnkey system suits you, with its pre-installed mainframe operating system, there is no need to install Hercules from this site. Volker Bandke's MVS Tur(n)key System
Jürgen Winkelmann's TK4-
IBM OS/360 MVT, a non-virtual storage operating system. Jay Maynard has a good installation procedure at Introduction to Generating and Running OS/360 on Hercules
IBM DOS/VS. See Yahoo user ceo1944's 2314DOS.zip. This link downloads a zip archive of JCL and instructions from the Yahoo group H390-DOS/VS; free registration required. 
IBM DOS/360. There are at least four installation procedures available. The first three are in the H390-DOS/VS Yahoo group (free registration required) and the fourth is a stand-alone web site.  Bill Carlborg's DOS360-2314.zip (downloads a .zip archive). 
 Ben Huntsman's DYI-DOS360.zip (downloads a .zip archive). 
 Kevin Leonard's DOS-360 26.2
 https://sites.google.com/site/dos360install/. This site is loosely modeled on Jay Moseley's MVS 3.8j site noted above. 
IBM VM/370. See the VM/370 R6, page on the cbttape.org site. Turnkey versions of VM/370 are available on David Wade's G4UGM's Vintage and Classic Computer pages
Linux. Mainframe versions exist for the following. Some of these are not open source, and installation generally requires configuration of a mainframe Channel-to-Channel adapter to enable network connectivity for installation and/or post-install security updates. Debian Download a s390x CD or DVD. 
Fedora. Scroll down the page until you reach 's390x Architecture' at the bottom of the page. 
Gentoo. The s390x is included under '(experimental)' for 'Experimental architectures'. You know what that means. 
Red Hat. Paid license or 30-day trial only. Red Hat supports Fedora as its open source alternative. 
SUSE Enterprise Server. Paid license or 60-day trial only. 
Michigan Terminal System (MTS). The Michigan Terminal System Archive includes a turnkey distribution that has been tailored for use with Hercules. Additional helpful information may be found at https://try-mts.com/why-try-mts/
SATK. Harold Grovesteen's Stand Alone Tool Kit offers a collection of tools for creating mainframe assembly language programs on your computer for later execution within Hercules. The binary floating point test programs and scripts were created using SATK and serve as examples for the assembler's capabilities and use. 
TXXOS. Tommy Sprinkle's 'Bare Metal Programming for the IBM 370 Mainframe' web site walks you step-by-step from IPL'ing a simple listing program through building a disk-resident operating system. 
 See Frequently Asked Questions, starting with question 2.01 Can it run z/OS, z/VM, z/VSE? for more details on available operating systems and licensing matters. 
Mainframe Software Documentation Documentation for the Linux distributions, the Michigan Terminal System, SATK, and TXXOS may be found on their respective web sites. 
 Documentation for the IBM operating systems is a different matter; much of it was published before the Internet existed. The Bitsavers site and its mirrors contain a repository of scanned, and in some cases, OCR'd, IBM hardware and software reference manuals. The DOS360Install site has a couple of essential DOS/360 manuals that are not on Bitsavers. 
 Bitsavers is organized first by manufacturer, then by machine. Within machine one can find operating system documentation. Use the following shortcuts to the Bitsavers site. And explore...one can find very useful information in unexpected places on Bitsavers. 
 System/360 hardware & software manuals
 System/370 hardware & software manuals MVS software manuals. Also see OS/VS2 software manuals. OS/VS2 was IBM's original name for MVS. 

Hercules Documentation and Useful LinksThe Web/HTML documentation is in a 'how-to' style with examples. The downloadable PDFs are comprehensive reference documentation.
