1. Hercules Emulator Overview

Hercules is an open source software implementation of the mainframe System/370, ESA/390 and z/Architecture hardware. The Hercules emulator runs under Linux on several hardware platforms in-cluding the Intel Pentium PC, under Windows 98, Windows NT, Windows 2000, Windows XP, Windows Vista, Windows 7, Windows Server 2003, Windows Server 2008, Solaris, FreeBSD and under MAC OS X 10.3 and later.

2. Hardware and Software Prerequisites

2.1 Hareware Prerequisites

2.1.1 Processor

Hercules does not necessarily depend on the Intel Pentium architecture. It also has been built, installed and run successfully on an Alpha 21164, SPARC and on z/Architecture Linux/390 systems.

• • • Pentium with 500 MHz or equivalent processor (minimal)
    • Pentium with 1 GHz or equivalent processor (moderate)
    • Pentium with 2 GHz or equivalent processor (average)
    • Pentium with 3 GHz (Dual or Quad Core) or equivalent processor (good)
    • 2 or more Pentium Quad Core processors with 2.66 GHz or equivalent processors (optimal)

 2.1.2 RAM

The more RAM installed in the system the better Hercules will perform.

• • • 128 MB RAM (minimal)
    • 512 MB RAM (moderate)
    • 1024 MB RAM (average)
    • 2048 MB RAM (good)
    • 4096 MB RAM (optimal)

2.1.3 Disk Storage

The disk storage requirements for Hercules depend entirely on your requirements. The runtime Hercules system requires only small amount of disk space.

The following table shows how much space is occupied for each virtual DASD volume on your PC hard disk(s) for some of the supported device types.

Table 1: DASD Device Capacity

2.2 Software Prerequisites

2.2.1 Operating System

The Hercules Emulator runs under Windows 98, Windows NT, Windows 2000, Windows XP, Windows Vista, Windows Server 2000 and Windows Server 2003. Although Windows 98 and Windows NT are possible candidates for running Hercules, their use is not recommended because of limitations in stability (especially Windows 98), limited networking capabilities and lack of support.

2.2.2 Installed Software on a Hercules System

It is recommended to have the following software installed:

• • • Windows 2000, Windows XP, Windows Server 2003 with latest service packs and hot fixes
    • Software firewall, especially if there is no hardware firewall in the LAN
    • Antivirus software with on demand and on access checks active

Depending on your requirements other commonly used utilities include:

• • • Network sniffer
    • Performance monitor / Task monitor
    • FTP program

2.2.3 3270 Terminal Emulator

Pre-install 2370 terminal emulator, just like wc3270, pcom.

2.3 Required programs

2.3.1 Hercules Emulator

The Hercules executables are the heart of the emulator and a mandatory component. This is the software implementation of the System/370, ESA/390 and z/Architecture mainframe hardware and processor machine code instruction set.

3. Installing the Hercules Emulator

3.1 Downloading the Binaries

　　The "ready-to-run" binaries can be downloaded from http://www.hercules-390.org. For Windows users there are currently two varieties available:

• • MSVC Windows installer package (filename "hercules-v.rr-w64.msi" or "hercules-v.rr-w64.msi")
  • MSVC binaries only archive (filename "hercules-v.rr-w64.zip" or "hercules-v.rr-w32.zip")

We use MSVC Windows installer package.

3.2 Installation Steps (MSVC Windows Installer Package)

To start the installation dialog run the .MSI executable file. A welcome window is presented first.

Figure 1: Welcome Window (MSVC Installer Package)

Clicking on "Next" continues the installation process.

Figure 2: Installation Directory Selection (MSVC Installer Package)

If you do not want to change any of your choices, click on "Next >" to start the actual installation process.

The installer now begins to copy files to the destination directories.

Figure 3: Installation Progress Bar (MSVC Installer Package)

If necessary the process of copying files can be stopped by clicking on "Cancel".

After a few seconds the installation process will finish and present the final window.

Figure 4: Installation Complete (MSVC Installer Package)

Click on "Close" to terminate the installation dialog and proceed to customise your installation as de-scribed in the following sections.

4. Getting Application Development System(ADCD)

The ADCD is built on a twice per year schedule typically coinciding with the release of new versions of z/OS. The ADCD is created to provide qualified Independent Software Vendors (ISVs) with the latest z/OS System along with associated middleware products at the latest available maintenance level. For quite some time now, we have been offering the z/OS System also via download option, in addition to the DVDs. 

The currently supported ADCD environments are:

• • z/OS 1.9 December 2007 under Red Hat and Flex
  • z/OS 1.9s Summer 2008 under Red Hat and Flex
  • z/OS 1.10 December 2008 under Red Hat and Flex

We use z/OS 1.10 to build virtual z/OS inver environment.

5. Configuring Hercules Emulator

5.1 Creating the Hercules Configuration File

When starting the Hercules Emulator from either a DOS command line or via the Hercules Windows GUI, you may specify the name of a configuration file. The following figure is a sample of the configuration file, ensure that your configuration file references your DASD devices correctly. The paths from the configuration file may be relative.

6. Configuring 3270 Terminal Emulator

6.1 Configuring 3270 terminal

Open a 3270 terminal emulator, set host to localhost or 127.0.0.1 and set TCP port to 3270.

The following figure is a sample of 3270 terminal emulator configration.

Figure 5: 3270 terminal configration

7. Starting Hercules Emulator

7.1 Power on Hercules Emulator

When starting the Hercules Emulator from either a DOS command line or via the Hercules Windows GUI, you may specify the name of a configuration file as a parameter:

HERCULES [ -f filename ] …

where filename is the name of the configuration file. The default filename if none is specified during the startup is ‘hercules.cnf’. The name of the default configuration file may be overridden via the environment variable HERCULES_CNF.

The following is a sample to power on the Herclues Emulator

Figure 6: Power on Herclues Emulator command

Hercules should start and you should see something similar to:

Figure 7: Hercules Hardware Console - Console window

Press ‘ESC’ to switch to the graphic mode. Start two instances of the 3270 terminals that was configured in "6. Configuring 3270 Terminal Emulator". The first will be the console terminal, the second will be the TSO terminal. 

You should see two terminals binded to Hercules(0700 and 0701 in the following figure, if you connect Hercules by local, the Assignment will be 127.0.0.1 or localhost):

Figure 8: Hercules Hardware Console - Device and status display

Until you IPL the system, both of the 3270 terminals will show the following:

Figure 9: 3270 terminal - Hercules power on

7.2 IPL z/OS

To IPL z/OS, press ‘L’ for IPL:

Figure 10: Hercules Hardware Console - Select Device for IPL

Then press the device number to IPL the z/OS.

Figure 11: Hercules Hardware Console - IPL

During the IPL progress, console will stop at the following figure:

Figure 12: Console terminal - IPL 1

Use the following command to reply "I":

r 00, i

Figure 13: Console terminal - IPL 2

After IPL, you will see the follwoing firgure in TSO terminal:

Figure 14: TSO terminal - Welcome

You may login as ‘IBMUSER’ with the password ‘SYS1′.

Have FUN!

8. Stopping Hercules Emulator

8.1 Stopping z/OS

To stop z/OS, you can type the following command in console:

s shudown

Figure 15: Stopping z/OS - input shutdown command

During the stopping progress, you can type the following command to check the active jobs:

d a,l

Figure 16: Stopping z/OS - check active jobs

When the s shutdown command complete, you will find there is only three jobs left:

Figure 17: Stopping z/OS - check active jobs left

Then you will use the following command to stop JSE2:

$P JES2,term

Figure 18: Stopping z/OS - stopping jes2

Until now, z/OS has been stopped.

8.2 Stopping Hercules Emulator

 In the Hercules graphic mode, you should press ‘E‘ to external interrupt the system.

Figure 19: Stopping Hercules Emulator - external interrupt

After input ‘Y‘, you should input ‘S‘ to powerdown the Hercules Emulator:

Figure 20: Stopping Hercules Emulator - powerdown

Input ‘Y‘ to confirm, you will jump to the windows command line:
