Alter system trigger - substitution

Question

Hello.
By the documentation, there is restriction for trigger on alter command: "The trigger will not be fired by an ALTER DATABASE statement".
I'm trying to use BEFORE SHUTDOWN and AFTER STARTUP triggers to database and I'd need also cover situations:
- alter system quiesce restricted
- alter system suspend
- alter system enable restricted session
- alter system unquiesce
- alter system disable restricted session
- alter system resume
I'm using ALTER SYSTEM command (not ALTER DATABASE), but trigger isn't fired too. Is there any way how to catch and do some PL/SQL pre/post processing events described above?
Thanks.

Oracle Version ?
if ur on 10.x.x.x.x
Check
sql> select space_limit/1024/1024 "Limit MB",round(space_used/1024/1024) "Used MB"
2* from v$recovery_file_dest
SQL> /
Limit MB Used MB
2048 1681
If limit and used field equal then increase db_recovery_file_dest_size parameter size
SQL> show parameter db_recovery_file_dest_size
NAME TYPE VALUE
db_recovery_file_dest_size big integer 2G
SQL> alter system set db_recovery_file_dest_size = 3g;
System altered.
