Library Asset Reporting System for the Entire Corporation
DCMS/LARS is a mainframe-based software product that enables the customer to find which production library members are no longer in use and can safely be moved to a history archive. Many mainframe sites avoid cleaning their libraries because of the time-consuming effort and risk of problems. This often leaves hundreds or thousands of library members that have not been used in decades. Removal of obsolete library members makes future analysis easier and less error-prone because of the reduction in confusing library clutter.
LARS Features
LARS determines which members are in use by using a combination of the following sources:
- Your site’s SMF archive. SMF (System Management Facility) data is written by the z/OS operating system to capture information on most system events. LARS uses SMF data to track the use of programs, jobs, and partitioned dataset (PDS) members. Most z/OS sites collect SMF data and typically keep a year or more of this information.
- Your DCMS/XREF database. Prior installation of DCMS/XREF is required for LARS. XREF is used to find relationships between various types of members. For example, when a program is in use, then its component COPYBOOK members are also in use.
- Your DCMS/CCS database (optional). CCS is used to associate members that exist on multiple libraries. For example, a program may consist of a source member, a load module and (in the case of DB2) a DBRM member.
- IBM’s Module Fetch Monitor (optional). MFM can be used to detect the use of dynamically called sub-programs. For example, a COBOL program that calls another routine when the DYNAM compiler option is in effect loads the sub-program at execution time. SMF does not record this event.
- LARS uses these information sources to capture usage history for your production members. It then provides this information in a TSO/ISPF online query and with a batch reporting tool. Among other reports, you can ask for a list of your unused members.
