DB Cache Full or Redo Log Full?

Is there any way that Oracle can write to datafiles in the middle of a transaction?
Iam reading, processing and writing very large sized lobs which gives error that "no free buffers available in buffer pool".
When in lobs, a lob is not written until the whole tranaction finishes - but in my case the lob size is large than the size of the data buffer cache.
The error is "ORA-00379: no free buffers available in buffer pool DEFAULT for block size 8K"
Exact question I would like to know now is that which buffer is full; data_buffer_cache or the redo log buffer?
If data_buffer cache, then is there a mechanism which allows to write data to dtafiles in the middle of a transaction as i have to do processing with lobs - which are 3 to 4 times the size of the db cache size.
I am referring to the same problem outlined in an earlier thread.
Thanks

r.- Oracle writes to the datafiles only commited transactions according to some elements
Iam reading, processing and writing very large sized
lobs which gives error that "no free buffers
available in buffer pool".
r.- You have to increase the size of the buffer Pool
When in lobs, a lob is not written until the whole
tranaction finishes - but in my case the lob size is
large than the size of the data buffer cache.

data_buffer_cache. In what version you are ?

allows to write data to dtafiles in the middle of a
transaction as i have to do processing with lobs -

r.- Oracle does not write to the datafiles in that way

Full Online + REDO Log backup failing

Hi Experts,
We have a failing backup when running a 'Full Online + REDO Logs' scheduled via DB13 (ERP6/Windows 2008/Oracle 10.2.0.4)
Whilst it is successful in backing up the datafiles and the REDO logs to the remote destination, it fails to catalog the backup, displaying the following message:
ORA-19625: error identifying file
Backup_Destination\BEFSDJTA\SR3.DATA10
ORA-27041: unable to open file
OSD-04002: unable to open file
O/S-Error: (OS 5) Access is denied.

BR0536E RMAN call for database instance EQ1 failed
BR0280I BRBACKUP time stamp: 2011-04-21 07.20.49
BR0532E Cataloging backups of all database files failed
From what I understand, RMAN runs under the OracleService<SID> service, which calls the oracle.exe process, which is owned by the local user SYSTEM. This accounts for the access denied problem when accessing the remote destination using the RMAN utility.
As a test, I'm aware that if I change the ownership of oracle.exe to a non-local, domain user (<SID>adm), I can run RMAN commands without the permission denied error occuring. (performed this on a Sandbox)
The problem when I use this <SID>adm account as the oracle.exe owner, is that the SAP application Work Processes won't connect to oracle.
My questions are:
Is it a valid workaround to change the process owner of oracle.exe to something other than the local SYSTEM user?
If so, what are the criteria that need to be met for the new domain user to ensure that the SAP application is stable?
Does anyone know of an alternative workaround?
Thanks,
Chris W

Hi Markus,
Thanks for the response.
I've managed to get the SAP application to run with Oracle using the <SID>adm account as the OracleService<SID> owner.
The original problem with the SAP work processes in connecting with the Oracle database was due to the Oracle listener services also being owned by local user SYSTEM.
I changed the listener services ownership to <SID>adm (as well as the OracleService<SID>) and this allowed the connection between the SAP work processes and Oracle.
Also, I gave the domain <SID>adm account local administrator rights (same as SYSTEM) and have seen no problems since the switch.
I can also access a remote host using the RMAN utility - problem appears to be solved.

Redo logs full - how to remove

Hello!
From time to time our database redo logs get full (oracle is running), we go to rman and delete them and everything is fine again.
This time it is the first time we experience this problem when oracle is NOT running.
When we want to start in sqlplus with "startup", oracle DOES NOT start up - we get the error message:
ORA-03113: end-of-file on communication channel
The alert log shows the message:
ORA-19815: WARNING: db_recovery_file_dest_size of 4070572032 bytes is 100.00% used, and has 0 remaining bytes available.
ORA-19809: limit exceeded for recovery files
This time we cannot use RMAN. The problem is, that rman (rman - connect TARGET sys/orac@orcl) only functions with a running database, otherwise we get the error message:
ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
So we deleted the redo logs manually and rebooted, but oracle seems to does not "SEE" this manual deletion. The error message
stays the same.
We wanted to convert our spfile to a pfile, change the redo logs max value to a higher value, and convert this back to a spfile, but this
is also only functionning when the database is running.
Does anybody has a solution for this problem?
Thanks for your help in advance

Hi,
Its more of a backup policy issue than a technical problem, I would like to go like this....
1. Check if I really need archive logs (in case of Test/Dev environment only export backup should be enough)
2. if you can afford to loose archives better change DB in no arch mode (But you will not be able to take online backup of DB through RMAN)
2. If you need Archives for sure, try getting more space allocated to your archive dest Drive/FS.
Normally we have a practice of keeping the size of arch dest Drive 2 times larger than DB generates in the duration of backup cycle...i.e. if you take arch backup once every day, I would keep archive dest FS size to be able to keep 2 days of archives.

Rahul

Redo log and Disk Full

hi
all
i'm new oracle DBA. i had one problem is
my Database is in archive mode. now redo log is available but not archive and my disk is full. so i couldn't open my Database what i have to do next step please help me...
Thanks in advance

Take a proper copy of all the archived log files from the archive destination to some backup media like tape(for future recoverability) and delete them off from the disk to avail for space on the disk.
You will then be able to open your DB and proper archiving will take place.
What is happening?
The ARCHiver process is finding no space on the disk to archive the redo log files and thus Oracle stops doing any further action since it is in archive log mode.

Archiver is unable to archive a redo log because the output device is full

Dear Experts,
When I logged to EM of my DB 11g R2. I found the following:
- Database Instance Status : Down
- Details
The instance has been terminated by a database process because of a fatal internal condition, or a critical background process was killed by the user.
Archiver is unable to archive a redo log because the output device is full or unavailable.
- Agent Connection to Instance
Status: Failed
Details: ORA-01034: ORACLE not available
Thank you in advance for any help you provide
Best Regards

Redo log file is full or not

Hi everybody,
In Oracle I wanna know the current capacity of a log group, so I will know/estimate when it will be switched. For example, I have three log groups 1, 2 and 3, each log group has only 1 member of size 10MB. So I want to check how full the current log group is? 1MB, 3MB or 7MB... When it's 9MB I know it's going to switch.
But currently I can't find the solution. I see the LAST_REDO_BLOCK in v$thread. v$thread presents status of current log group. When I do 'alter system switch logfile', LAST_REDO_BLOCK resets to 0 and increase slowly. I try to create table and insert multi rows, and LAST_REDO_BLOCK increase fast. So anybody can tell me if LAST_REDO_BLOCK is the current number of blocks in the current log group, and I can calculate the current size of a log group? If not, any possible solutions?
Sorry for my bad English and thank you for reading.

Error in db6conv failed due to transaction log full

Hi,
I have a huge problem with my production system.
I was executing db6conv v4.08 to convert a table to a new tablespace and it stopped due to a transaction log full.
Now I have this situation:

I check the job db6conv_job_soffcont1 with status scheduled.
The problem is that when I want to execute this jobs it gives me an error:

DIFFERENCE BETWEEN THE FULL AND BULK-LOGGED RECOVERY MODEL

DIFFERENCE BETWEEN THE FULL AND BULK-LOGGED RECOVERY MODEL

In bulk logged recovery mode certain bulk operations are minimally logged. In FULL recovery mode these are fully logged. These bulk operations are as mentioned below
1. SELECT INTO
2. BULK IMport operations including BULK INSERT and BCP
3. INSERT INTO SELECT command using the OPENROWSET(BULK) function
4. Partial updates to columns having large value data type
5. Using WRITE clause in UPDATE statements
6. Index operations e.g CREATE INDEX, ALTER INDEX REBUILD , DROP INDEX
In Bulk Logged Recovery Mode when you execute these operations SQL Server only logs the fact that these operation occured and information about space allocation. The actual change in the data is maintained in the BCM (Bulk
Changed Map)
Since the actual changes are not recorded in the log file, the log file size in the reletively less in size but this tradeoff comes with the price of increased backup time. This is so because during the log backup its not just the log being backup, but also
the extents that are marked by the Bulk Changed Map as changed.

FINANTIAL DOCUMENTS MISSING --- ORACLE LOGS FULL

Hi Experts,
9 documents are missing and when they were saved the system showed the message "update has been stopped". This was because of the Oracle LOGS (full).
When Oracle problem was solved the documents were not found in SM13 to recovered.
Any clue?
On the other hand If a have finantial documents in QAS how can I put it on PRD?
Regards.

Hi,
Schedule your backups according to the full backup time.
Do a test of full backup and fine the time that it takes to complete the full backup. You can include "plus archivelog" if you want your archive logs to be backed up along with the full backup. This is most preferred as this makes restoration easy too.
If your full backup takes, say, 4 hrs to complete and if you schedule your full backup at 00 00 hrs on your scheduler, then schedule the archive backups after 04 00 hrs. This will solve your problems with missing archive backups.
>> "But from RMAN specialist I heard that this may cause problems with full backup. During full backup also archive logs are backed up (at the start and end) so there might be a problem with accessing the file that is used by another process. And this may cause problem with full backup - which we want to avoid especially."
This will throw out errors if your input to full backup consists "delete input" for your archived logs, else the process will not have any problem and succeed.
Also when one or more of backups run concurrently, "ORA-00230: operation disallowed: snapshot control file enqueue unavailable" error may occur but this is rare case.
Thank you!!

DB2 transaction log full

I am installing ECC6 for DB2 on RedHat AS4 platform. During import ABAP phase(running3, waiting1, completed15, total19), I have a strange error. System tell me that DB2 transaction log full. It seems unreasonable. System should know data volume during data import. I increased DB2 log file size when I got the error, and now, import ABAP is still in progress. Does anybody know why I got this error? Thanks so much.

Hello
there should be an SAPINST-Dialog similar to
"SAP System > Database Import"
where you can enter
Number of Parallel Jobs
In newer installations you started in "Default Mode" you need to review your summary dialog and mark the corresponding dialog for respecification.
Then you can specify your desired number of parallel Jobs
Best regards

The content download cannot be performed because there is not enough available space in cache or the disk is full.

I deploy all office package via Application deployment. But many system getting failed due to error "The content download
cannot be performed because there is not enough available space in cache or the disk is full.".
I delete the cache old file/folder. Now the cache disk space is available. But still this systems showing same error. And it is not retry also. need help for retry application download if failed due to cache disk.

You should review what your default client cache size is being set to (default 5GB) and then look at the size of the office content you are trying to deliver.
If the content of the office application exceeds your maximum client cache size setting then the download and subsequent installation will fail.
Note that normally the download of applications should overwrite old content in the cache unless you have set them to be persistent, the exception to this is the above case.
To resolve this you will need to increase the client cache size. There are a few ways to achieve this, you can do this either from the Config Manager console via right click tools or via a script that you can run against your clients. Others might like to
comment on how best to achieve this (if this is indeed your problem).

Database log full

what are the option to free up the log?
1. kill spid filling up log.
2. backup the tran log - to disk or truncate only or no_log.
3. change the database to simple recovery mode, delete ldf file and then revert back to full recovery mode.
4. detach database, delete log file and reattach mdf again.
I am especially interested to know if the last two are commonly used in case dba is not able to free up log using other ways.
thanks.

First find why the log file is not truncating,
SELECT name,
log_reuse_wait
FROM sys.databases;
The recovery model dictates log behavior and whether the log will truncate on checkpoint or requires a transaction log backup, full and bulk logged recovery requires that you backup the log to keep the log size manageable, refer
here to the different kinds of backups and their affect on the T-Log.
The action you take will be dictated by the reason for the log not truncating. There are numerous reasons that the log does not truncate including replication, mirroring, transaction log backup, active transaction, etc. BACKUP LOG TRUNCATE ONLY
is no longer supported as it removes the ability to restore the database to a point in time.
The last two options are last ditch efforts to regain control of the log file size and should only be done after a full backup of the database is taken to insure that a viable backup is available.

Staging server archive log full

Hi ,
i have encountered my staging server having archive log full which i do not understand.
i hope anyone can help clarify my doubts
Production server : oracle 10G , RedHat
Staging Server : oracle 10G , runnings on windows
source server : DB2
the staging server is simply a link between the Production server & db2
i am running my procedures on the production server which is getting db2's data via the staging server thru dblink
i have encountered the error : ORA-00257 : archiver error : connect internal only, until freed when i ran some recovery which involved some 20M to 40M records being loaded at the same time
what i do not understand is why would the Oracle running on windows have its archive log full when it's just a link betw the production and db2
pls advise
tks & rgds

Just go to the archivl log destination and delete some/all of the archive logs then I think the problem will be resolved.
OR
connect to RMAN then run
run {
allocate channel ch1 device type disk;
backup format '/u04/rman_backup/RMAN_ARCH_<%s:%t:%p>.bkp' archivelog all delete input;
It will take the backup of your all archivelog and then delete the archive logs from your current archive log directory.

I have message "spool is full" in system log

I have message "spool is full" in system log. What to do

You should periodically delete old spool requests from the database by scheduling report RSPO0041 for background processing. The report deletes old spool requests according to the criteria you specify. It also maintains the TemSe temporary sequential object database, deleting any orphaned or corrupted spool data accumulated

Pin redo logs into smart flash cache (Exadata Flash PCI F20 cache)

Need to know if we could pin redo logs into smart flash cache.
For example to pin table..
we use Alter table dhaval storage (cell_flash_cache keep) -----
Similarly can we pin redo logs into flash cache ?
If not, what is the alternative to put redo logs into flash cache ?

At Oracle OpenWorld the Exadata Smart Flash Log feature was announced. The Smart Flash Log feature requires Exadata Storage 11.2.2.4.0 or later, and Databases version 11.2.0.2 Bundle Patch 11 or greater. This feature allows a modest amount of flash to be used as a secondary write place. It wites redo to both flash and disk and returns the call to the db for the first one that finishes. By doing so it improves user transaction response time, and increases overall database throughput for IO intensive workloads.
