The MPE/iX User Logging facility provides a method for recording
events (for example, to record additions and modifications
to user databases and files). MPE/iX commands and intrinsics are
used to setup logfiles and record to them. Power failure recovery,
buffering, and logfile overflow handling can be done for the user
automatically. Multiple user processes may share the same
logfile and share the
system process that manages it.
This allows the User Logging overhead to be shared between multiple
user processes.
User Logging can be used to keep a record of changes made to data
for historical purposes or to aid in the recovery process of lost
data due to application and system failures.
