Result
Current messages and old messages are logged in ring memory files that are overwritten as soon as they reach a certain size.
The first part of the file, which logs the last restart of the database instance, is excluded from the write cycle. A new log file is created each time the database system is started.
Error messages are logged continuously in a file. Delete any obsolete entries manually.
