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.
