Log sequence

In production database 8.1.6
I got a message at a particular time
cannot allocate log sequence seq#
Thread 1 advanced log sequence seq#
After this, I increased the log buffer value
and number of log files also.
But I am getting the same error. Is there
any suggestions please?

Check the status of the log files by using following query
select * from v$log;
On log file should have status='CURRENT' and should have the highest sequence number;
Other's should have status = 'INACTIVE' and ARC=Y.
Its possible that the redo logs are waiting to be archived because of space problem.

    I am cloning database with RMAN duplicate database command and at the and of the script I got RMAN-06055: could not find log sequence 86362 thread 1 .
    The script is :

  • In Noarchivelog mode "Thread 1 cannot allocate new log, sequence 3298"

    Hi,My database mode is noarchivelog but i see my alert.log "Thread 1 cannot allocate new log, sequence 3298"
    what it`s mean?
    I have enough disk space.

    This is very similar to the your still open thread cannot allocate new log, sequence
    Better protocol would surely be to acknowledge the references given then, and why you think they do or do not apply.
    Please get one of these threads marked as answered and continue on the other.
    Please also indicate:
    1) is your database hung.
    2) Output form this query:

  • Next log sequence to archive in Standby Database (RAC Dataguard Issue)

    Hi All,
    I just had implemented Data Guard in our server. My primary Database is RAC configured, but it is only single node. The other Instance was removed and converted it to Developement Instance. For the reason I kept the primary as RAC is when I will implement dataguard, my Primary Database is RAC with 7 nodes.
    The first test is successful, and I was able to "switchover" from my primary to standby. I failed in the 'FAILOVER" test.
    I restore my primary server and redo the setup.
    BTW, my standby DB is physical standby.
    When I try to switchover again and issue archive log list, below is my output.
    SQL> archive log list;
    Database log mode Archive Mode
    Automatic archival Enabled
    Archive destination USE_DB_RECOVERY_FILE_DEST
    Oldest online log sequence 38
    *Next log sequence to archive 0*
    Current log sequence 38
    SQL> select open_mode, database_role from v$database;
    OPEN_MODE DATABASE_ROLE
    MOUNTED PHYSICAL STANDBY
    ===============================================
    SQL> archive log list;
    Database log mode Archive Mode
    Automatic archival Enabled
    Archive destination USE_DB_RECOVERY_FILE_DEST
    Oldest online log sequence 38
    *Next log sequence to archive 38*
    Current log sequence 38
    SQL> select open_mode, database_role from v$database;
    OPEN_MODE DATABASE_ROLE
    READ WRITE PRIMARY
    In my first attempt to switchover before I failed in "FAILOVER" test, I also issue +archive log list+ in both primary and standby database, and if I remember it right, next log sequence on both should be identical. Am I right on this?
    Thanks in Advance.
    Jay A

    Or Am i just overthinking on this?
    Is dataguard only looking for the current and oldest log sequence?

  • Thread 1 cannot allocate new log, sequence 714 - Checkpoint not complete

    I'm working in a Oracle 10g database, running on RHEL. The alert_*.log file is putting out this type of text for the past few months:
    Thread 1 advanced to log sequence 713 (LGWR Switch)
    Current log#2 seq# 713 mem# 0: /dbfiles/..../onlinelog/filename.log
    Current log #2 ..........
    Thread 1 cannot allocate new log, sequence 714
    Checkpoint not complete
    Any ideas to get me pointed in the right direction is appreciated,
    Thank you in advance,
    Wes

    The immediate fixes Vishal suggests are the standard answer, but there is more to it, as the MOS doc he references shows. Additional questions I would ask:
    How long is the delay between the inability to switch and when it actually switches? How many datafiles do you have? What is waiting in the db?
    In general, I find making log files sized for the rare massive updates, then using the built-in timeouts to switch every 20 or 30 minutes (depending on management recoverability expectations), helps avoid some of these problems. More specifically, run a statspack or awr (if licensed) report for maybe an hour during heavy times, and see what it thinks the waits are. Tuning is an iterative process, and sometimes different things can cause similar symptoms. Sometimes fixing the biggest problem (which is often poor SQL) can radically change the symptoms observed. Other times you find you have dying hardware, or someone messed up a switch configuration.

    mseberg wrote:
    It just a warning. I would read these two notes:
    I suspect the OP is more worried about the apparent two minute gap between the "cannot switch" and the "advanced" at     19:39:18 and 19:41:12 respectively. Did the switch really have to wait for that two minutes, or is this a spurious threat caused by an anomaly in the writing of the alert log.
    As a cross check, I would examine v$event_histogram (or an AWR/Statspack for the interval) for time spent in the event "log file switch (private strand flush incomplete)". In prinicple I wouldn't expect to see waits longer than a few (less than 10) milliseconds; if the histogram shows long waits consistent with the alert log reports than I'd contact Oracle because something odd is happening.
    (Footnote - it's possible that the event times out after a limited interval, log file sync used to time out after 1 second and has recently changed to something shorter and adjustable, so 2 seconds may (for example) appear as 20 x 0.1 seconds.)

  • Cannot allocate new log, sequence Checkpoint not complete

    Hi,
    Im having very frequent log switches and Im getting error as
    " cannot allocate new log, sequence Checkpoint not complete"
    I was having 3 redo log groups with 50 MB each. After I found this error in the alert log; I increased teh number of redo log groups to 6 with 50MB each. Still the issue is not getting resolved.
    Please suggest what will be the best solution for this.
    Following is a snippet from alertlog.

    Hi Sir,
    Although i too had suggested increasing the redo logfile size, but after going through [http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:69012348056] i was little confused as Tom has mentioned
    Another way is to make the log files smaller, hence increasing the frequency with which we checkpoint ---- Can you explain why so.
    I was a little surprised when I read that posting - but noticed it was dated May 2000 - when databases were still quite small and less busy. (And Tom suggested 25MB as being "modest" rather than "tiny" - which is probably what many people would call 25MB these days). And May 2000 probably means 8.0 or 8.1 - and the whole log buffer, redo generation, checkpointing technology has changed a lot since then.
    Basically, if you hit "checkpoint not complete", you need more online log space so that it's possible during the busiest times to keep generating redo log information while the checkpoint queues are being cleared far enough to allow older log files to be recycled.
    You can do this by adding more log files, or by increasing the sizes of the log files you use. Tom's point, I think, was that if you chose the option to add more files and kept them small (or even made them smaller) then the volume of dirty data blocks that you could create while filling a log file would be small, so the database writer wouldn't have to do much work to make each log file available for re-use. (I'm not sure I'd agree with the approach, though - even for 8i - because it could easily lead to an increase in the volume of datablocks written, even if it did bypass the checkpoint issue).

    Thread 1 cannot allocate new log, sequence 12
    Private strand flush not complete
    由"Private strand flush not complete"引起的 cannot allocate new log一般可以忽略, Private strand是10g引入的新特性
    Heap size 2919K exceeds notification threshold (2048K)
    该信息是由于 10.2.0.1 这个版本的默认 "_kgl_large_heap_warning_threshold" 参数过小, 一般可以忽略。
    调整个 "_kgl_large_heap_warning_threshold" 参数和 升级到10.2.0.1 版本均可以 让该"Heap size 2919K exceeds notification threshold (2048K)"信息不再出现, 当然一般也可以忽略该问题

    Dear sb92075,
    I have increased the size of the redo log files to 15M to see how things work.
    select * from v$logfile;
    select group#, sequence#, bytes, archived, members, status
    from v$log;
    alter database drop logfile group 1;
    alter database
    add logfile group 1 ('F:\MAINDB\LOG_01.log') SIZE 15M;
    alter system switch logfile;
    alter database drop logfile group 2;
    alter database
    add logfile group 2 ('F:\MAINDB\LOG_02.LOG') SIZE 15M;
    ALTER SYSTEM CHECKPOINT GLOBAL;
    alter database drop logfile group 3;
    alter database
    add logfile group 3 ('F:\MAINDB\LOG_03.LOG') SIZE 15M;So, all I have to do now is just wait and see how things go after this, right?
    When these statements were being executed, I noticed some errors also but I think I should ignore them for now.
    Some sample messages are:
    Completed: alter database drop logfile group 3

    alter database
    add logfile group 3 ('F:\MAINDB\LOG_03.LOG') SIZE 15M

  • Thread 1 cannot allocate new log, sequence 28703

    Hello,
    I have a problem in my production database. I have an Oracle database 10.2.0.2 64 bits, and Checking the alertlog I see this message some days ago:
    Thread 1 cannot allocate new log, sequence 19943
    Private strand flush not complete
    Current log# 1 seq# 19942 mem# 0: E:\ORADATA\INCARLOP\REDO01A.LOG
    Current log# 1 seq# 19942 mem# 1: F:\ORADATA\INCARLOP\REDO01B.LOG
    My archivelogs size is 90 MB and I have enough free space in my filesystem
    what can be the problem?
    Thanks!!!

    The problem is caused by the fact that Oracle wants to start using a redo-log file which is still in use by a running checkpoint.
    Most of the time this problem is solved by adding more redo-log-groups.No, what you are describing would be more the "+Check point not complete+" error, which could be solved by adding more logfile group or increase the current size.
    The message of the OP is similar, but not the same. It would rather means that log switch cannot occur because the redo has not been written, this could be a disk contention to write down the redo. If this is eratic behaviour it could safely be ignore.

  • Thread 1 cannot allocate new log, sequence 1558 Checkpoint not complete

    hi,
    i m working on oracle 10g rac database on aix machine . i m getting this error on peck time
    Thread 1 cannot allocate new log, sequence 1558 Checkpoint not complete
    i read lots of documents and they asked to increase size of redo file or add more redo files.
    can u plz describe me y m i getting this error ? & how adding redo file can help in this error.
    thxs

    when yours current redo log filled and then started to switch another log then checkpoint occurs ,this checkpoint started to write dirty buffer from buffer cache to datafile , you cannot reuse this logfile unless checkpoint process writes alls dirty buffer from buffer cache to disk which contained this redo log file.If you attempt to reuse the same log file which cause to checkpoint upon log switch then you will get this error.
    Typically this error comes where yours number of redo log switches occuring too frequently or you have less number of redo logs.
    lets say if you have 2 redolog file A and B,yours A redolog filled and then oracle switch from redo log A to B,checkpoint occurs,DBWRn started to write dirty buffer to disk meanwhile yours redo log B also get filled antoher log switch occurs to be attempt to reuse redo log file A ,but redo log A will not be entertain unless the previous checpoint completed to write alls dirty block from buffer cache to hard disk which is contained thats redo log A.
    Adding redo log will be helpful in this case that redo log will switch to another new added redo log say C and A log file will get more time to be completed checkpoint which he/she contains contents.
