Journal Archive Manager (JAM) is an archive management tool for electronic journal files at the headquarters location.  It automatically manages the bundles and journal files created on the IBM 4690 store system by the IBM Electronic Journal program or the ESCAPE application.  The bundle handling function and the journal archive manager function are independent of each other.


The information contained in a retailer’s electronic journals is invaluable, but the sheer number of files can be overwhelming.  The IBM Electronic Journal program (5697-G45) and the EDJ ESCAPE application each provide a mechanism at the store level to bundle the journal files to simplify retrieval of the data.  ESCAPE provides a utility program for the user to open the bundles and distribute the files one bundle at a time on the server side.  When a user has a large number of stores to process, the utility program may not be the most efficient method.  A new application has been created to automate opening bundles and to remove expired journals from the current directories.  This new application is Journal Archive Manager (JAM)

Bundle management is typically used at the central server location that receives the bundle files from stores.  Bundles are stored in the active bundle folder on the server.  JAM extracts the journals from the bundles and places the journals in a journal folder in the proper sub-directories   After the journals are extracted, the bundle is moved to a bundle archive folder.  The bundle archive folder is defined with a storage lifetime of up to 3,000 days.

Journal archive manager is used to maintain journals on a central server or on individual computers.  Archive management takes place after bundle management occurs.  Journals from bundles are subject to the archive management settings immediately.  The archive manager is responsible for moving or deleting old journals.  Journals in the main journal folder are given a storage lifetime of up to 400 days.  When that time expires, the older journals are either moved to an alternate journal folder or deleted.  The journal lifetime in the alternate journal folder is up to 3,000 days.  At the end of that period, the old journals are deleted automatically.
