Hi,

i am a newbee ( not only in this forum, as a dba too ).
So i have this question:
We have som ORACLE 8i DB-Servers and one 10g DB-Server.
The DB/Instances wil be shutdowned immediate via scripts
After the offline Backup they will be startet ( under 10g
via ORADIM -STARTTYPE inst )
On the 8i Servers the REDOLOG Files (3 Groups/ 2 Members) have a
at every LOG-Switch a change-Date/Time ( seen under Windows/
View/details).This is correct an can be viewed in the ALERT-log
At our 10g Server with a very small DB ( 800 MB Size Usertablespace)
there can`t see a change DATE/Time but in the ALERT-log seems
all to be correct.
The REDOLOG-Files have the Date after the start of the DB/Instance.
The DB is in archivelog-mode.
The REDOLOG-Files have 10 MB size.

Are there any problems ( time i.e. ) or misconfigurations visible and
what´s the reason ?
Can you help / explain this behavior of 10g ?
Here a part of the ALERT-LOG:

The file OS timestamp does not matter, Oracle never uses it.
