Setup Hercules Environment
Objective
These tutorials are intended to introduce new hobbyists to the Hercules environment. These tutorials use VM/ESA 2.4.0 available on the Internet Archives as an example but the same patterns may be useful for any other installation.
* NOTE * This environment is highly “opinionated” and prescribes a set up that may not work for your needs. The setup that is prescribed is intended to provide consistency in the documentation and tutorial stages.
Procedure
1 - Install the SDL Version of Hercules
Install Hercules as described on the SoftDev Labs (SDL) site.
This software is under active development from the GITHUB repository and the documentation, while marked “obsolete” is still quite excellent.
2 - Establish Folder Structure
This configuration assumes that the filesystem is set up as follows:
{Root} ... Command and Configuration Files
├───batch ... Stand-Alone Utilities
├───conf ... Configuration File(s)
│ ├───includes ... Optional/Included Configurations

3 - Unload Distributed DASD Images
The distribution images are assumed to be on CD-ROM (ISO) images.

4 - Compress the Images
The uncompressed images are very large and bulky to manipulate, additionally they are unnecessary in their distributed form. To make these more manageable, the images can be compressed at the Operating System level (in the case of Windows) or at the file/container level. Hercules supports a “Compressed Count-Key-Data” virtual device format which we will use for this purpose.
Original DASD Size: 12.3 GB OS Compressed Size: 2.75 GB (Windows 10) Hercules CCKD Size: 0.772 GB
4.1 - Windows CMD strings to compress using dasdcopy
If you already have an existing system and want to include existing shadow files in the new CCKD images:
Assuming this structure:
<your_disk_directory>
| (contains)
+- shadows
|
+- <your shadow files>
You may use the following CMD snippet to convert the base images in <your_disk_directory> combined with the contents of the shadow files into the new CCKD format files.
Hint: Remove @echo once you have the command structure the way you want it.
@for %h in (<your_disk_directory>\*_1.12*) do @echo dasdcopy -z "%h" SF="%~dphshadows\%~nh.shadow" "%~dpnxh.cckd"
If you only wish to compress the distributed files:
@for %h in (<your_disk_directory>\*_1.12*) do @echo dasdcopy -z "%h" "%~dpnxh.cckd"
Example:
Assuming that you are positioned in the directory E:\Uncompressed, executing the
above command string would result in the following enumeration of dasdcopy:
<zterm><nowiki> E:\Uncompressed E>@for %h in (*_1.12*) do @echo dasdcopy -z "%h" "%~dpnxh.cckd" dasdcopy -z "E:\Uncompressed\240RES_1.123" "E:\Uncompressed\240RES_1.123.cckd" dasdcopy -z "E:\Uncompressed\240W01_1.124" "E:\Uncompressed\240W01_1.124.cckd" dasdcopy -z "E:\Uncompressed\240W02_1.125" "E:\Uncompressed\240W02_1.125.cckd" dasdcopy -z "E:\Uncompressed\240W03_1.126" "E:\Uncompressed\240W03_1.126.cckd" </nowiki></zterm>
Note that the inconsistently named file will need to be copied:
dasdcopy -z "E:\Uncompressed\240SPL.128" "E:\Uncompressed\240SPL_1.128.cckd"
4.2 - Position the CCKD Files
Move the COMPRESSED images into the proper DASD file location as previously indicated.
The final resulting folder structure should look like this:
\VMESA\DISKS\VMESA │ 240RES_1.123.cckd │ 240SPL_1.128.cckd │ 240W01_1.124.cckd │ 240W02_1.125.cckd │ 240W03_1.126.cckd │ └───shadows (This directory will be needed in subsequent steps)
