Sinardy,
First, I suggest you find some time and sit down and READ the Oracle
documentation. Otherwise you are going to get a large number of "RTFM"
emails, and some flaming as well.
Now.. the alert log is created (if it does not already exist) or written to
every time Oracle wants to record an event that has happened in the
database/instance. So log switches will be in there, database shutdown and
startup messages, errors dealing with the infrastructure of the database
(failure to extend a rollback segment, failure to get space in the temp
segment, disasterous database errors etc) There are other messages as well,
I'm not going to list every one.
Bdump contains trace files that relate to the Oracle background process --
anything generated by smon, pmon, etc
Udump contains trace files that relate to specific user Oracle processes
Cdump contains core dumps, associated with one or another trace files in the
bdump directory.
