AcuServer provides remote file access services through the use of a memory resident program (daemon) named acuserve, running on the file server. The client application executes using an ACUCOBOL-85 or ACUCOBOL-GT client-enabled runtime.
The runtime recognizes access requests to remote files and uses Remote Procedure Calls (RPCs) to acuserve to fulfill the requests.
On the server, acuserve waits for file access requests, manages their execution, and returns the result to the client requester.
A typical AcuServer interaction might be:
1. An application running on a network machine attempts to READ a file.
2. The Acucobol runtime recognizes that the file to be read is located on a remote system and packages the request as an RPC to acuserve on the file server.
3. acuserve receives the RPC request, executes the READ and returns the result to the client, completing the interaction.
