For the error to occure we need one full online redo log (current) and one offline, but still active (not all the data writen to the DB files).

One could ofcourse configure multiple DBWRs if they see a need. 2) LGWRs also seem to do a good job of flushing from redo buffers to redolog files. check here

Read all about it!Often overlooked is the REDO file size.Once it is full, a checkpoint will occur, and a new archive created.Your choice there depends on the log block write speed.

The solution do your problem is either enlargement of your redo logs or creation of new ones.
The solution (optimal) one will be 1) Put ur Redologs on a seperate disk (if they are not already) 2) Increase the number of redologs.

There is very heavy database activity and this activity means that the database is generating redo logs faster than it can archive them. Troubleshoot "Can not allocate log, archival requi...

(We def.
The problem may be more the speed at which the redo log files are written to the archive destination? It is the checkpointing process (either using CKPT or LGWR) that is invariably the real bottleneck. If you had 3 logfiles (a,b,c) when we switched from A to B - that triggered a checkpoint. 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

However I believe that if you enlarge/create more redo logs the problem will be solved. http://electrictricycle.net/cannot-allocate/cannot-allocate-memory-because-no.html I asked the team about the process. Make 2 more redologs (4 total, on the same drive) 4. PRTG is easy to set up & use.
IF the checkpoint triggered by switching out of A is not yet complete - we cannot use A right now, we must wait. After restart it become working again, for an hour, and then - ppof! When C is filled we switch to A. http://electrictricycle.net/cannot-allocate/cannot-allocate-vector.html If this error occurs during one-off loading of data into the database then either ignore the error or consider running the database in non-archive-log mode for the data loading.
Even if the disks were really slow, why should it take all that long??
