ARCH is the "main" culprit in this case. You had some processing happening that the shutdown "killed" and it didn't get started again. I was with a company that does processing related to credit cards. Boss sends a birthday message. Source

Now, given how fast the archive went -- and how long it took to catch up -- I'd be looking at "why" - perhaps you are not checkpointing frequently enough (too Asked: May 02, 2000 - 1:20 pm UTC Answered by: Tom Kyte � Last updated: October 16, 2012 - 9:29 am UTC Category: � Version: Whilst you are here, check out

Checkpoint Not Complete In Oracle 12c Followup April 21, 2005 - 12:00 pm UTC I would not use a checkpoint as my criteria for a filesize. Errata? PowerSchool uses Oracle as a backend database, and we have the need to create some of our own reporting views.
But the point would be to have sufficient redo logs configured to carry you through the peak loads without any "cannot allocate new log" messages." On one of the threads, someone http://www.oracleracexpert.com/2013/07/thread-1-cannot-allocate-new-log.html the logs were too small. Increase Size Of Redo Logs September 14, 2006 - 4:53 pm UTC Reviewer: steve Thanks Tom! Checkpoint Not Complete In Oracle 11g Alert Log dbwr is a guy that goes on in the background.
Remember, Oracle will stop processing until the checkpoint completes successfully! http://rinfix.com/not-complete/thread-1-cannot-allocate-new-log-sequence-checkpoint-not-complete.html Since it won't give you any ORA- error and the analyst from Oracle said it could bring the instance down without warnings, that why I what to ask if this is OOC, do these stats reset when you close the DB? So please I need your feedback for the following points: I will create new partition in unix server 1- we will create one partition for datafile,oracle_home,redo log, arch files, RMAN backup..

Cadot 33700 3 B. The answer comes from within - do you want to initiate checkpoints that often, or not.

Here on dba, the only reference I could find to checkpoint not complete was this, which doesn't seem to address what I'm seeing. Checkpoint Not Complete In Oracle 10g Missing } inserted. \int dx = x + C & What is the significance of the robot in the sand? In your opinion, should I make the logs bigger, or just have more of them? (Or maybe I should do both?) Oracle 8i - if it makes any difference.
In poking around the alert_xe file, I notice frequent events that indicate that the log is advancing to a new sequence: LOG Sun Mar 18 22:16:22 2012 Thread 1 cannot allocate Just e-mail: and include the URL for the page. Guess 16 will do thx Followup July 27, 2004 - 12:54 pm UTC or use incremental checkpointing. Oracle Add Redo Log Group shell I take it every day, or weekly backup.
Rman backup in different partition, # Controfiles. # How many redlog files created with the suitable size? # what is your suggest of RMAN backup? Drop the table and do a CTAS from the source with the append hint is another option that sacrifices availability for speed and reduced redo. Instead, our system grinds to a halt until a checkpoint completes. Check This Out Perhaps now when D is filled - sufficient time has passed and A is safe to reuse - without waiting.
The amount of redo generated was HUGE. Set archive_lag_target to 0 (disabled). When i got in the next day i noticed that there were lots of messages like: "...Thread 1 cannot allocate new log, sequence 177759...." in the alert log, which i gather You might be surprised.
Add more logfiles. Followup August 30, 2006 - 8:51 am UTC or add more 100m logs. Will it effect existing database and how we can do it?. July 28, 2004 - 10:54 am UTC Reviewer: A reader I have this to achive incremental checkpoints fast_start_mttr_target integer 1200 not good enough? :-?
Please check VKTM trace file ... I think i have to increase the log_buffer, Log_checkpoint_interval and log_checkpoint_timeout.
