 +====== PLP/MCU Sessions ======
 +
 +A 'session' is the term we use to describe how PLP/MCU organizes the work you perform with this software on your computer; a synonym might be 'Project'. Each time you have a file of records that you want to process, PLP assigns a new, unique, Session Id, and then creates a folder named with that Session Id; within this 'Session folder' will be stored all results and workfiles generated by the program.
 +
 +===== Session Id =====
 +
 +The Session Id is eight digits long, and used throughout PLP and MCU to uniquely identify sessions. When a file is first loaded in PLP, it is assigned a session ID, and this ID will stay with the file throughout its life in PLP, and in MCU. 
 +
 +In the Session ID, the first six digits contain a datestamp (YYMMDD), and they are followed by a two digit sequence number (starting at 1). Here are a few examples:
 +
 +  09122501   --Session #1 (01) on Christmas Day, 2009 (091225)
 +  10032502   --Session #2 (02) on March 25, 2010 (100325)
 +  10032504   --Session #4 (04) on March 25, 2010 (100325)
 +
 +
 +===== Session Folder =====
 +
 +When PLP/MCU is installed, a folder called 'Sessions' is created in the installation directory ((by default, this is C:\Program Files\TMQ\PLP)). 
 +
 +For each session created in PLP/MCU, a subdirectory, named with the Session Id, is created in the Sessions folder. Here is an example of how the Sessions folder might look on a typical system:
 +
 +{{:mcu:session_folders.jpg?600|}}
 +
 +Within each session folder are two more folders, one called 'Results' and the other called 'Work'. The Results folder contains all of the MARC files produced by PLP/MCU, along with any reports created during the processing. The Work folder contains 'work' files created by the programs as they run--these files can be used to troubleshoot problems. For PLP, this will be a detailed SQL log; for Self-PLP, this will also contain a memory dump of the database used for the processing; and for MCU, there will be an Action log plus a folder containing all MARC records that may have been individually edited.
