Abstract

An interactive retrieve optical storage system, when the system administrator defines an optical controller he also defines how many interactive retrieve programs (sessions) that he wants running to that optical controller and he defines the interactive retrieve wait time. When the first user attempts to interactively retrieve a document from optical, the system creates an interactive retrieve request data queue and starts up the number of programs (sessions) that the system administrator defined. These programs (sessions) stay active until the system administrator ends them (most likely at the end of the day). This interactive retrieve request and all subsequent interactive retrieve requests will be placed in this interactive retrieve requests data queue.

Storing and Retrieving Image Documents in an Optical Storage

      An interactive retrieve optical storage system, when the system
administrator defines an optical controller he also defines how many
interactive retrieve programs (sessions) that he wants running to
that optical controller and he defines the interactive retrieve wait
time.  When the first user attempts to interactively retrieve a
document from optical, the system creates an interactive retrieve
request data queue and starts up the number of programs (sessions)
that the system administrator defined.  These programs (sessions)
stay active until the system administrator ends them (most likely at
the end of the day).  This interactive retrieve request and all
subsequent interactive retrieve requests will be placed in this
interactive retrieve requests data queue.  One of the programs that
reads this data queue will process this request.  It processes the
request by either copying the document from optical to DASD and then
returning a return code in the return code data queue, or by placing
the document in the document content data queue and then sending back
the return code in the return code data queue.

     The program that initiated the interactive retrieve request by
placing the request in the interactive retrieve request data queue is
left in a wait state waiting for the return code to be returned in
the return code data queue.  If too much time expires before a return
code is placed in the re...
