SuperKIX for CardDemo

The original README is README.md.

Server configuration

For the server to work, some configurations needs to be done. This is done in a config.toml file containing the following fields:

  • pct_files, an array of paths to files containing the Program Control Tables, i.e. informations that link transactions to programs.

  • fct_files, an array of paths to files containing the File Control Tables, i.e. informations that link transactions to files.

  • program_folders is an array of pathes to folders where the GnuCOBOL modules will be found.

  • map_folder is the folder where the physical BMS maps will be found.

  • job is the name that will be given when the SuperKIX application asks for a JCL job id.

  • the [good_morning] section contains informations on the transaction that will be run when a new terminal is connected:

    • prog: the name of the program that will be run when the terminal is connected;
    • tranid: the name of the transaction that will be used when the terminal is connected.

NOTE: All the pathes in the config.toml file must be relative to the config.toml file.

Example:

pct_files = ["pct.json"]
fct_files = []
program_folders = ["_build/cobol/modules"]
map_folder = "_build/map"
job = "CARDDEMO"

[files]
data_path = "app/data/EBCDIC/"
handler = "vsam"

[good_morning]
prog = "COSGN00C"
tranid = "CC00"

Data configuration

A [files] section is dedicated to the management of files. It must contain two fields:

  • data_path containing the path to the data files used by the application;
  • handler which contains either "vsam" or "bdb" depending on the backend used to handle files.

Example:

[files]
data_path = "app/data/EBCDIC/"
handler = "vsam"

Building the application

Run make DATA_MGMT=<data_handler> from this project's directory where data_handler is:

  • sql for SQL persistent data management;
  • vsam for virtual access storage method.

NOTE: Default paths and executable names are given in Makefile.defaults; to change them in order to match your configuration, you may create a Makefile.config with suitable assignments to those same variables. The default configuration notably assumes that padbol, gixpp, and cobc are available in the PATH.

Running the application from Rust sources

You must have Rust installed with cargo. We assume your project is at path ~/cobol_app and the padbol project at ~/padbol.

cd ~/padbol/superkix
cp -r ~/cobol_app watcher
cargo run -- run watcher

then, in another terminal:

pkill -HUP server

You can now use:

cargo run -- run watcher

from ~/padbol/superkix to run the server and wait for a terminal connection.

To connect to the server you can use any 3270 emulator that supports TN3270E, and connect to localhost:1024. We recommend the x3270 project and in particular the c3270 emulator you can used that way:

$ c3270
c3270> connect localhost:1024
<ESC>
c3270> disconnect
c3270> exit
