OEMHi Danut,
the database is running in archive logs, the archive process can copy =
fastly the redo logs.
when I query v$log, I see ARCHIVED is "YES", but STATUS is "ACTIVE".
sometimes, when running batch processes on database , this problem =
appears.
because of the completeness of the process, commit statement is at the =
end of process.
So that the commit statement is not too often.

Hi,
I met with this problem before, and I found that the problem exits = only when the database is not in archive logs, or the archive process = can not copy fast enough the redo logs.
Do you have the archive redo logs on separate hard drive ?
How often do you commit during the mass insert/update ?

Hi all,
Our system
DUNIX 4.0D
Alpha 4100 with 2 GB RAM, 2 x 467 MHZ CPU
Oracle 7.2.3
I have a problem.
I have 8 RedoLog files each 83 MB(Total 650 MB). In my
system, sometimes Oracle hangs, at that time I got the following ;
SQL> select group#,status from v$log;
GROUP# STATUS
---------- ----------------
11 ACTIVE
12 ACTIVE
13 ACTIVE
14 ACTIVE
15 ACTIVE
16 CURRENT
17 ACTIVE
18 ACTIVE
.. and in the alert log file I had the following...
contents of alert.log:
Thread 1 cannot allocate new log, sequence 8230
Checkpoint not complete
Current log# 12 seq# 8229 mem# 0: /ctl/redo/log12SEVDE.rdo
=20
The reason for this, there is a very large Update/delete/insert =
transactions
from 1 (or more) process.
Someone offered to increase number of DBWR background process.
how to do it?
thanks,=20
zeliha.
