Delete transaction log file

Hi,
I have three T-log files in my database, Now I want to delete 2 Transaction log files.
Can I do the below action:
1. dbcc shrinkfile(log1,truncateonly)
2 dbcc shrinkfile(log2,truncateonly)
2. Then remove the file using command or SSMS.
Regards

Hi Satheesh,
What about this:
Can I use the below procedure:
dbcc shrinkfile(LOG2,emptyfile)
dbcc shrinkfile (LOG3,emptyfile)
alter database PRT remove file LOG2
alter database PRT remove file LOG3
Note: I have already LOG1 as my primary logfile existing there, I want to remove only secondary logfiles

How to delete Transaction Logs in SQL database

Hi,
Can any one explain me the process how to delete the transcation logs in SQL database.
Thanks
Sunil

Sunil,
Yes you can take online backup in MS SQL server.
The transaction log files contain information about all changes made to the database. The log files are necessary components of the database and may never be deleted. Why you want to delete it?
I am taking any backup, do i need to turn off the SAP server that is running at the moment or can i take it online
There are three main types of SQL Server Backup: Full Database Backup, Differential Database Backup and Transaction Log Backup. All these backups can be made when the database is online and do not require you to stop the SAP system.
Check below link for details

Client Deletion, Transaction log getting full.

Hi Gurus,
We are trying to delete a client by running:
clientremove
client = 200 (*200 being the client we want to remove)
select *
The transaction log disk space allocated is 50GB, it is getting full (in simple mode) and client deletion never completes. The size of the table it is accessing is 86 GB, and i think 200 client will be occupying around 40-45GB. Client 200 has 15.5 million rows in the table.
I am i giving proper command ?is there any explicit commit i can include or any workaround for deleting the client and not hammer the log file.
Thanks guys

Hi,
Backup the active transaction log file and Shrink the file directly.
Please refer the following SAP Notes to get more information.
[ Note 625546 - Size of transaction log file is too big|https://websmp130.sap-ag.de/sap%28bD1lbiZjPTAwMQ==%29/bc/bsp/spn/sapnotes/index2.htm?numm=625546]

Which version of SQL Server u are using ? SP Level ?
Frequently perform Transaction Log backup (BACKUP TRANS) to remove inactive space within the Transaction Log Files.
Please refer [Note 307911 - Transaction Log Filling Up in SQL Server 7.0|https://websmp130.sap-ag.de/sap%28bD1lbiZjPTAwMQ==%29/bc/bsp/spn/sapnotes/index2.htm?numm=307911] to get more information about the reasons for such kind of situation.

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.
mayooran99

yes, 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!!

How to delete archive log files from ASM through Grid Control

Hi
Anybody suggest me how to delete archive log files from ASM through Grid Control.
Thanks

It is important to specify both, the oracle version and os version when posting, so confusions can be avoided.
In this particular case, since you are referring to asm and grid control you could be talking about either 10gR1, 10gR2 or 11gR1; but I strongly suggest you to avoid us to be guessing. In either case, you sould go to the maintenance tab of the target database and program a scheduled 'delete noprompt obsolete;' procedure. This will purge the information stored at the Flash recovery area, which I assume you have declared inside the ASM.

Big transaction log file

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
D

I'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.

If 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

I would also deploy some tracking methods to see if you can hone in on the culprits, i.e. If you want to see if the problem is coming from an internal Device/Machine you can use one of the following
MS USER MONITOR:

Also check out ExMon since you can use it to confirm which mailbox is unusually active , and then take the appropriate action.

How can I delete a Log File in EM

I created a log file in the Log Configuration from "SOA Infrastructure -> logs -> Log Configuration", but later I found I cannot remove the new created log file. There only are Create, Create Like, Edit Configuration, View Configuration options in EM. Is there any way to delete the log file? I am using SOA suite 11.1.1.3 Thanks.

Highlight the said file on the Music section of your Library, and press the Backspace key. When asked whether you want to move to the trash, say yes. Then you may download it again looking in Your Account in the purchased section.

Manual delete archived log files

Because we don't have RMAN in our development server, I need to use manual operation to delete all archived logs. Is my procedure correct and safe?
SHUTDOWN IMMEDIATE
STARTUP MOUNT
ALTER DATABASE NOARCHIVELOG;
EXITRun OS command to manually delete archived log files:
rm /oradata/arch/*
Login to sqlplus

If the archives are deleted manually in open mode, how can Oracle match the archived logs' retention policy? Does Oracle store the archived logs in data dictionary?While you can delete archivelogs manually any time you want, you should let rman manage them with appropriate rman commands, preferably in a script that you schedule for regular execution.
Some of your questions lead me to question if you understand that archivelogs are not actively open by the database, and they technically are not part of the database. They are simply a series of "offline" copies of the online redo logs. They are written to once, when an online redo is being archived, then they just sit there until needed for a recovery.

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

HI 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

Want to delete out.log files

Log files having a file name of {servername}-out
n.log (where
n is a numeric identifying separate log files) accumulate in
great numbers in the folder, \JRun4\logs\. Some log files appear to
expand beyond their typical 200kb size into the hundreds of
megabyte range. We're looking for a solution that will
automatically delete these log files before they accumulate beyond
control.
What might be available to handle this, such as a solution
that will delete old log files after a certain limit is reached?
We are running CF MX 7.02 on Window 2003 OS.

When to delete Archive Log files ? and is safe to delete ?

Hi all,
I have a question, my DB is running in Archive Log mode and is growing day by day, so should I delete archive log files and where i find that my which files are old and how to delete theses files, for info I also take full RMAN and export backup regularly .
abbas

Well, if you're not comfortable with Backup and Recovery principles, i'd advise you to first read TFM: Backup and Recovery Concept(click) for you data safety's sake.
Anyway, just to give you a glance at what could happen, immagine suche a situation where your database is made of 5 different datafiles (whatever they are - SYSTEM, SYSAUX, UNDO, ...), controlfiles and online redo logs. If, for example your backup is done in a timeline such as:T0 : Backup datafile F1 and F2
T1 : Backup datafile F2 and controlfile
T2 : Backup datafile F3, F4
T3 : Backup datafile F5
T0' : Backup datafile F1 and F2
T1' : Backup datafile F2 and controlfile
T2' : Backup datafile F3, F4
T3' : Backup datafile F5
...If your server crashes (for example is thrown though the 5th floor window..) in order to make a full recovery, you could proceed multiple ways.
. Restore files from Tx' backups. Then you'd need every archived redo logs created from T0' to now in order to be able to do a full recovery.
. Restore files from backups; T3, T0', T2' and rectreate controlfile. Then you'd need every archived redo log created from T3 (inclusive).
. Restore Tx backup, ...
. Restore ...
and so on.
What's important is that you're at least able to resynch a full-set backup. What I mean is: if you restored "T3, T0', T2' and rectreate controlfile", in order to open the database you'll absolutely need every archived redo log created between T3 and T2' inclusive. If one is missions, you won't be able to open it.
That is the principle. Read the concept book I linked to get more infos.

Yoann.
