ISUPDATER (Update Facility)
Overview
isCOBOL implements a software update feature that allows you to download updates through the HTTP and HTTPS protocols. It's a general-purpose updater that can be used to download any type of file, not only COBOL programs.
The update process
The isupdater tool connects to a given HTTP server and checks if a new version of the files is available. If a new version is found, the isupdater downloads the files. The HTTP server (server side) and isupdater (client side) are configured through property files. Files are stored in ZIP archives on the server and are automatically unzipped once downloaded to the client.
isCOBOL Server as an HTTP server
The isCOBOL Server can work as an HTTP server for isupdater, so you don’t have to set up an HTTP server in order to take advantage of the software update feature.
Post update operations
At the end of the update process, isupdater can automatically run a program that takes care of post update operations such as copying the downloaded files in the proper folder. This program can be a standard COBOL program or a Java class executable from the command line (e.g. a Java class with a main() method).
Post update launch
Isupdater can automatically run a given class at the end of the update process. This class must be accessible in the Classpath.
