Unable to delete records as the transaction log file is full
My disk is running out of space and as a result I decided to free some space by deleting old data. I tried to delete 100,000 by 100,000 as there are 240 million records to be deleted. But I am unable to delete them at once and shrinking the database doesn't
free much space. This is the error im getting at times.
The transaction log for database 'TEST_ARCHIVE' is full. To find out why space in the log cannot be reused, see the log_reuse_wait_desc column in sys.databases
How can I overcome this situation and delete all the old records? Please advice.

In order to delete the SQL Server need to write the information in the log file, and you do not have the place for those rows in the log file. You might succeeded to delete less in each time -> next backup the log file each time -> next shrink the
log file... but this is not the way that I would chose.
Best option is probably to add another disc (a simple disk do not cost a lot), move the log file there permanently. It will increase the database work as well (it is highly recommend not to put the log file on the same disk as the data file in most cases).
If you can't add new disk permanently then add one temporary. Then add file to the database in this disk -> create new table in this disk -> move all the data that you do
not want to delete to the new table -> truncate the current table -> bring back the data om the new table -> drop the new table and the new file to release the temporary disk.
Are you using full mode or simple recovery mode ?
* in full mode you have to backup the log file if you want to shrink it

this is because of a problem at the WS server (it might mostly be a windows server).
You can request the WS team to have a look into this issue. it is not a PI problem. -
Why is the transaction log file not truncated though its simple recovery model?
My database is simple recovery model and when I view the free space in log file it shows 99%. Why doesn't my log file truncate the committed
data automatically to free space in ldf file? When I shrink it does shrink. Please advice.

If log records were never deleted(truncated) from the transaction log it wont show as 99% free.Simple recoveyr model
Log truncation automatically frees space in the logical log for reuse by the transaction log and thats what you are seeing. Truncation wont change file size. It more like
log clearing, marking
parts of the log free for reuse.
As you said "When I shrink it does shrink" I dont see any issues here. Log truncation and shrink file is 2 different things.
Please read below link for understanding "Transaction log Truncate vs Shrink"

Will the informations be recorded in the alert.log file? -----No.168
will the informations about the loss of a temporary file be recorded in the alert.log file?
Yes, because whe your database starts needs to "mount" a tablespace with temporary files (case of tablespace "TEMP"). But don't worry with a loss of this tablespace because doesn't contain nothing when database starts.

"The event log file is full" error - SAP LVS Report Viewer 1.0
Hi Experts,
I'm getting an error when trying to generate a report in SAP LVS.
Error:
The event log file is full
How do I resolve this? Anyone encountered this error?
Thanks in advance,
CyrousHi,
It seems that the audit log mechanism is activated, at your system. But, if you didn't set the parameter DIR_AUDIT, audit log will be created under "/usr/sap/<SID>/<instance>/log", not "data" folder. You can check its default value on RZ11. Revise the parameters, below;
DIR_AUDIT = <path>
FN_AUDIT = audit_++++++++.AUD
rsau/enable = 1
rsau/max_diskspace/local = <SizeOfFile>

How to be notified for all ORA- Errors recorded in the alert.log file
based on Note:405396.1, I Changed the Matches Warning from the default value ORA-0*(600?|7445|4[0-9][0-9][0-9])[^0-9] to ORA-* in order to receive an warning alert for all ORA- errors.
but I just recieved the alert like the following:
Metric=Generic Alert Log Error
Time/Line Number=Mon Feb 25 23:52:21 2008/21234
Timestamp=Feb 26, 2008 12:06:03 AM EST
Severity=Warning
Message=ORA-error stack (1654, 1654, 1654) logged in /opt/oracle/admin/PRD/bdump/alert_PRD.log.
Notification Rule Name=Alert Log Error
Notification Rule Owner=SYSMAN
as you can see, the message only indicate the ORA-1654, nothing else.
How to set in 10g grid control to get the details alert that in the alert log like:
"ORA-1654: unable to extend index ADM.RC_BP_STATUS by 1024 in tablespace PSINDEX"
I can't believe Oracle 10g Grid control only provide the ORA- number without detailsGo to your database target.
On the home tab, on the left hand side under Diagnostic Summary, you'll see a clickable date link next to where it says 'Alert Log'. Click on that.
next click on Generic Alert Log Error Monitoring Configuration (its at the bottom)
In the alert thresholds put:
ORA-0*(600?|7445|4[0-9][0-9][0-9])[^0-9]
I believe that will pick anything up but experiment, its only perl.
If you want to test this use the DBMS_System.ksdwrt package but I would advise you only do so on a test database. If you've never heard of it, google it. Its a way of writing to your alert log.
Make sure you have your emails sent to long format as well. -
Hi
I have large database and i need to perform batch deleting without affecting the transaction log. So if I set the Recovery mode to Simple before deleting the transaction log will not grow ??

You CANNOT delete records in sql server without getting information logged in transaction log. Please note every thing in SQL Server is logged and logging depends on recovery model used. When you use simple recovery logging will
almost be same as full just after checkpoint logs would be truncated and also when log file grows 70 % of its size. This can only not happen IF some ongoing transaction is not holding the VLF or requires the VLF(virtual
log file)
So you made good choice to delete in batches. Also have a look on Lock escalation

The transaction log for database 'BizTalkMsgBoxDb' is full.
Hi All,
We are getting the following error continously in the event viewer of our UAT servers. I checked the jobs and all the backup jobs were failing on the step to backup the transaction log file and were giving the same error. Our DBA's cleaned the message box manually and backed up the DB but still after some time the jobs starts failing and this error is logged in the event viewer.
The transaction log for database 'BizTalkMsgBoxDb' is full. To find out why space in the log cannot be reused, see the log_reuse_wait_desc column in sys.databases".

Please mark this answer if it helpsPutting the database into simple recovery mode and shrinking the log file isn't going to help: it'll just grow again, it will probably fragment across the disk thereby impacting performance and, eventually, it will fill up again for the same reason
as before. Plus you put yourself in a very vulnerable position for disaster recovery if you change the recovery mode of the database: and that's before we've addressed the distributed transaction aspect of the BizTalkDatabases.
First, make sure you're backing up the log file using the BizTalk job Backup BizTalk Server (BizTalkMgmtDb). It might be that the log hasn't been backed up and is full of transactions: and, eventually, it will run out of space. Configuration
instructions at this link:
http://msdn.microsoft.com/en-us/library/aa546765(v=bts.70).aspx Your DBA needs to get the backup job running properly rather than panicking!
If this is running properly, and backing up (which was the case for me) and the log file is still full, run the following query:
SELECT Name, log_reuse_wait_desc
FROM sys.databases
This will tell you why the log file isn't properly clearing down and why it cannot use the space inside. When I had this issue, it was due to an active transaction.
I checked for open transactions on the server using this query:
SELECT
s_tst.[session_id],
s_es
.[login_name]
AS [Login Name],
DB_NAME
(s_tdt.database_id)
AS [Database],
s_tdt
.[database_transaction_begin_time]

And this told me the spid of the process with an open transaction on BizTalkMsgBoxDB (in my case, this was something that had been open for several days). I killed the transaction using KILL spid, where spid is an integer. Then I ran the BizTalk
Database Backup job again, and the log file backed up and cleared properly.
Incidentally, just putting the database into simple transaction mode would have emptied the log file: giving it lots of space to fill up again. But it doesn't deal with the root cause: why the backups were failing in the first place. -
How to find out whether the transaction logs are being truncated or not
Hi,
We are using Veritas Backup tool for Backups and restores on our MS SQL 2000.
One of our Veritas Tech has disabled the Truncation of Transaction Log Backup using the Job setup in Veritas. We want to confirm whether the Truncation is happening or not. I don't see any difference in the Transaction Log file size.
How to find out whether truncation is active or not?
Thanks
VijayHello Vijay,
On MSSQL truncation of transaction log does not shrink the size of the transaction log. It simply removes the content within the transaction log and writes it to the backup.
Meaning the free percentage within the transaction log will increase.
If you want to Resize the transaction log size, you need to do something else.
The shrinking procedure is given here:

i'm assuming this error was due to lack of growth space for ECCLOG1 datafile...am i right? if so how much should i allocate memory for this log ? or is there any workaround ?
thanks in advanceKasu,
If SQL is complaining that the log file is full then the phase of the install that creates the SQL data/log files has already occurred (happens early in the install) and the install is importing programs, config and data into the db.
Look at the windows application event log for "Transaction log full" events to confirm.
To continue, in SQL Query analyzer try:
"Backup log [dbname] with truncate_only"
This will remove only inactive parts of the log and is safe when you don't require point-in-time recovery (which you don't during an install).
Then, go to the SQL Enterprise manager, choose the db in question and choose the shrink database function, choose to shrink only the transaction log file and the space made empty by the truncate will be removed from the file.
Change the recovery mode in SQL Server to "simple" so that the log file does not grow for the remainder of the install.
Make sure you change the recovery mode back to "full" after the install is complete.
Your transaction log appears to have filled the disk partition you have assigned to it.
25GB is huge for a transaction log and you would normally not see them grow this large if you are doing regular scheduled tlog backups (say every 30-60 minutes) because the log will truncate every time, but its not unusual to see one get big during an install, upgrade or when applying hotpacks.

What is stored in a transaction log file?
What does the transaction log file store? Is it the blocks of transactions to be executed, is it the snapshot of records before beginning the
execution of a transaction or is it just the statements found in a transaction block? Please advice.
mayooran99yes, it will store all the values before and after that were modified. you,first, have to understand the need for transaction log, then, it will start to become apparent, what is stored in the transaction log
before the transaction can be committed, sql server will make sure that all the information is hardened on the transaction log,so if a crash happens, it can still recover\restore the data.
when you update some data - the data is feteched into memory and updated- transaction log makes note of it(before and after values etc).see, at this point, the changes were done but not physically present in the data page, they present only in the memory.
so, if crash happens(before a check piont\lazy writer could be issued), you will that data...this where transaction log comes handy, because all this information is stored in physical file of transaction log. so, when your server comes back on, if the transaction
is committed, the transaction log will roll forward this iinformation
when a checkpoint\lazy writer happens, in simple recovery, the transaction log for that txn is cleared out, if there are no other older active txns.
in full recovery you will take log backups, to clear that txn from the transaction log.
in transaction log data generally is faster because 1. it is written sequentialyl...it will track the data pageno, lsn and other details that were modified and makes a note of it.
similar to data cache, there is also transaction log cache, that makes this process faster.. all transactions before being committed, it will wait to make sure everything related to the txn is written to the transaction log on disk.
i advice you to pick up - kalen delaney, sql internals book and read - recovery an logging chapter..for more and better understanding...
Hope it Helps!! -
Hi,
I found a sql server database with a transaction log file of 65 GB.
The database is configured with the recovery model option = full.
Also, I noticed than since the database exist, they only took database backup.
No transaction log backup were executed.
Now, the "65 GB transaction log file" use more than 70% of the disk space.
Which scenario do you recommend?
1- Backup the database, backup the transaction log to a new disk, shrink the transaction log file, schedule transaction log backup each hour.
2- Backup the database, put the recovery model option= simple, shrink the transaction log file, Backup the database.
Does the " 65 GB file shrink" operation would have impact on my database users ?
The sql server version is 2008 sp2 (10.0.4000)
regards
DI've read the other posts and I'm at the position of: It really doesn't matter.
You've not needed point in time restore abilities inclusive of this date and time since inception. Since a full database backup contains all of the log needed to bring the database into a consistent state, doing a full backup and then log backup is redundant
and just taking up space.
For the fastest option I would personally do the following:
1. Take a full database backup
2. Set the database recovery model to Simple
3. Manually issue two checkpoints for good measure or check to make sure the current VLF(active) is near the beginning of the log file
4. Shrink the log using the truncate option to lop off the end of the log
5. Manually re-size the log based on usage needed
6. Set the recovery model to full
7. Take a differential database backup to bridge the log gap
The total time that will take is really just the full database backup and the expanding of the log file. The shrink should be close to instantaneous since you're just truncating the end and the differential backup should be fairly quick as well. If you don't
need the full recovery model, leave it in simple and reset the log size (through multiple grows if needed) and take a new full backup for safe keeping.

Very high transaction log file growth
Hello
Running Exchange 2010 sp2 in a two node DAG configuration. Just recently i have noticed a very high transaction log file growth for one database. The transaction logs are growing so quickly that i have had to turn on circular logging in order to prevent
the log lun from filling up and causing the database to dismount. I have tried several things to try find out what is causing this issue. At first i thought this could be happening because of virus, an Active Sync user, a users outlook client, or our salesforce
integration, howerver when i used exmon, i could not see any unusual high user activity, also when i looked at the itemcount for all mailboxes in the particular database that is experiencing the high transaction log file growth, i could not see any mailboxes
with unusual high item count, below is the command i ran to determine this, i ran this command sever times. I also looked at the message tracking log files, and again could see no indication of a message loop or unusual high message traffic for a
particlar day. I also followed this guide hopping that it would allow me to see inside the transaction log files, but it didnt produce anything that would help me understand the cause of this issue. When i ran the below tool againts the transaction log files,
i saw DDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDD, or OOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO, or HHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH.
I am starting to run out of ideas on how to figure out what is causing the log file build up. Any help is greatly appreciated.

Bulls on ParadeIf you have users with iPhones or Smart Phones using ActiveSync then one of the quickest ways to see if this is the issue is to have users shot those phones off to see if the problem is resolved. If it is one or more iPhones then perhaps look at
what IOS they are on and get them to update to the latest version or adjust the ActiveSync connection timeout. NOTE: There was an issue where iPhones caused runaway transactions logs and I believe it was resolved with IOS 4.0.1

Shrink Transaction log file - - - SAP BPC NW
HI friends,
We want to shrink the transaction log files in SAP BPC NW 7.0, how can we achieve thsi
Please can you throw some light on this
why we thought of ghrinking the file ?
we are getting "out of memory " error when ever we do any activity. so we thought of shrinking the file (this is not a production server - FYI)
example of an activity where the out of memeory issueee appears
SAP BPC excel >>> etools >>> client options >>> refresh dimension members >>> this leads to a pop-up screen stating that "out of memory"
so we thought of shrinking the file.
Please any suggestions
Thank you and Kindest Regards
SrikaanthHI Poonam,
Not only the excel is throwing this kind of message (out of memory) - the SAP note is helpful, if we have error in excel alone
But we are facing this error every where
We have also found out that our Hard disk capacity as run out of space.
we want to empty the log files and make some space for us.
our hard disk is now having only few MegaBytes now
we want to clear our all test data, log files, and other stuffs
Please can you recommed us some way
Thank you and Kindest regards
