I have developed my first basic cics application which is an examination system. Now I want this to be available for everyone. I don't have any idea whether this is possible or not. Can anyone guide me or provide any links or books for deploying in a server. Thank you
If your application is in a CICS region, it is available to "everyone" who has access to that region and your transaction.
CICS is a web application server, among other things. Those applications can be written in Assembler, C, COBOL, Java, PHP, PL/I, or Rexx.
If your application uses 3270 for its user interface and you want to make it available via the web, you can use a feature of CICS Web Support specifically for that.
