User Logging Programmer's Guide

Chapter 4  The User Logging Process 

There are two levels of User Logging; the user's level and the system
level.  At the user's level there are application and recovery programs
that access the logfile.  At the system level, there must be a User
Logging process running.

The User Logging system process allows up to 256 users to access a single
logfile at the same time (configurable at system startup); it handles
buffering and power failure recovery, and provides data about the status
of the logfile.  Before you can write to a logfile, a User Logging
process must be running for that logfile.  As a system process, the user
logging process does not belong to a particular user.  Any problems
encountered by the User Logging process will be reported to the System
Console.


NOTE  Since problems are reported to the System Console and the process
      must be restarted each time the system is started, responsibility
      for keeping the process running is usually given to the System
      Operator.
