SQL 2012 :: Schedule Truncating Of Logs?
Mar 19, 2014
We have many customers with a large database, many workers and many database transactions. Every night the databases are "full backupped". Regularly the logfiles (dbname_log.ldf) grow very large, for example a database (dbname.mdf) of 60GB and a logfile equal in size. When the drive becomes too full, I truncate these logfiles to free diskspace.
Question: is it a good decision to run a script that, after the daily full backup, truncates the logfile if it is larger than for example 10GB?

I am having trouble Truncating a Transaction Log. I`ve tried everything in Book Online.
I`ve backed up the database, I`ve tried DBCC SHRINKFILE, DBCC SHRINKDATABASE, BACKUP LOG TRUNCATE_ONLY ...etc, but it will not shrink. Any suggestions ? Thanks.

I've got a Sql server 2000 box that currently backs up to tape in full every night. I also want to back the box up off site but not in full (as 30GB is a little too much to transfer every evening).
So my plan was to do a full backup to tape at 7pm then a differential at 8pm (to transfer off site).
The problem I am having is that after my differential has been done the logs get truncated so if I want to replay them for any reason I need to get that differential back to site.
Anyone have any suggestions please?

Hi,
I am a new DBA is small company. Some of the databases grows by few GB everyday, so I am thinking to set automatic truncating for those databases.
Is this a best practise?
Can you please recommend Ideal Recovery model after reading my current model:
1. I do Full backup every night.
2. After 6 hrs, Differential backup.
3. After 1 hr Log backup.
Also please suggest me how many time should I do Re-Indexing?
Thanks,Dipak

Hi,
I have multiple questions and would appreciate any suggestions in resolving them. I'm a novice to these issues.
1) First of all, what is the exact command to setup the trunc. log on chkpt. option on for a transactional log of a SQL Server 2000 database? Is this option on by default? I have noticed for one of the databases I'm managing that the transaction log was over 12 GB, while the db was only 425 MB.
2) How's it possible to run a DBCC TRACEON to see the content of the transaction log to see if we are having any issues with any uncommitted transactions, i.e. updates, inserts, and/or deletes.
3) What are the commands to truncate inactive transactions and increasing the readbatchsize?
4) lastly, how do I validate transactional replication via checksum and find valid latency between a small number of changes that need to be committed between publisher and subscriber.
Thank you so much in advance!
Sincerely,
Alla

I have a production database which uses merge and snapshot replication. The Merge is for 3 tables. The snapshot is to update the rest of the data once daily. I use a Full recovery model and perform database backups (full, differential) and transaction log backups.
I have a database optimization plan which runs 4 times a week. This plan performs and integrity check and rebuilds the indexes. This optimization plan is growing the transaction log by about 8MB each time it is run and we are running out of space on the drive for our log files. The space is not being reused.
I saw in another post where Gail Shaw suggesting using SELECT name, log_reuse_wait_desc FROM master.sys.databases to see why the log space is not being reused. On the database in question, the above returns "REPLICATION".
A colleague tried to backup the transaction log a couple of times to truncate the log this weekend. She was going to perform a DBCC Shrinkfile command afterwards. But the truncate failed. Again looking into things it seems replication prevented the truncation.
We are looking at stopping the merge replication or even removing it to truncate the log file and then recreate the merge replication. How to handle shrinking the log file for now and then seeing if there are any checks or changes I can perform which will allow the transaction log space to be reused.

I got a request to truncate some tables on our testing servers.There are only 11 tables and i could go in and truncate them one after the other, but i need a script that i can use to truncate all the tables at a go. The tables also have no dependencies between them. A script to accomplish the same task if the tables had dependencies ...

I wanted to schedule the transaction replication. How do I do it? Currently I have set up a transaction replication which runs continuously and synchronizes the changes with immediate effect.
I need to configure a replication which will gather logs from the publication once in a day.

I am doing some general housekeeping for a couple of our SQL boxes in the Development environment. All the databases are set to Simple recovery mode. No need in anything else for these boxes. I have a database on all the boxes named "DatabaseMaintenance" Keeps things like all the sprocs for any type of database maintenance, etc....
I would like to schedule a single sproc that is located in the DatabaseMaintenance database to shrink the Transaction logs on a set schedule. They sometimes grow quite large while testing and developing. The thing that I cannot seem to get around, is when using the ShrinkFile command, one must use the Log Name. If this code is in a sproc that is located in the DatabaseMaintenance database, it will fail when attempting to call out to a different database. Because the Log does not exist on the database that the sproc is located.
How can I get around this small dilemma? There are only about 10 databases per box. To a point we really do not care what happens to them. They are on a Full backup schedule daily, just to keep the objects. As I stated previously, the logs will still grow huge at times while pumping data.
Is there a way to create a piece of code that will run against each database on the server, and be stored in a single database? Other than the system databases of course.

We use AlwaysOn availability groups, which has 2 SQL nodes configured (version: 11.0.3373.0), my full and differential backups are working for all my databases, however I am unable to perform any LOG backups.
I have double checked my Availability Group settings, and the backup preferences is set to: 'Prefer Secondary'
I've tried creating a maintenance job as well as using Ola Hallengren's maintenancescript job to back them up, but nothing is written to the drive. All jobs return successful every time, and take less then 3 seconds to run. There are no events being written in the SQL error log or event log.

Our backup system has worked ok for us to date. We can restore back to either full saves or up to a certain log (we take log backups on the hour). We've never had to, but wanted to test restoring to a point-in-time with the backup data.
What the system does is generates .mdf and .ldf files, which is essentially a full backup say in the middle of the night. It then creates .bak files for the log backups based on the backup set you want to restore.
I can detach the database and apply the .mdf and .ldf and re-attach the database, but to apply the .bak files I need to get the database into a (recovering) state. I can't seem to do that. Otherwise when I try to apply the .bak files the system says: The log or differential backup cannot be restored because no files are ready to rollforward.
How to apply a .mdf and then apply the .bak files?

Normally we use rebuild, reorganize indexes when it is required, I used a SQL job using maintenance plan to run daily and rebuild, reorganize indexes and update statistics but I do not know if it runs either they are required or not. Should this plan automatically execute the build upon required indexes to be rebuild or it fires either they are required to be executed or not.

Hi,
In my case I have to log the errors raised by any task in a package to either windows event log, text file or SQL server. Also I need to send an email notifications to a group of people telling them about the error.
Now can I use SSIS package logging for logging the errors into the required destinations. I mean right clicking on the package and selecting Logging, then adding the required log providers and enabling the events for logging into those. I think I have to upfront select the log providers to log the error, I will not have the liberty to log the error to the destination, the name of which is passed as a variable to the package. This is okay with me though.
Now what will a custom log provider help me to do in this case. Also can I somehow configure my package to call the send mail task everytime an error is raised.
Also, one more option can be developing a package that only does the error handling. It will take in the paramters or the error codes and descriptions, the destination to write to and a flag to send mail or not for that particular type of error.
What do you think? Kindly advise.
Thanks in advance for your help and time.
Regards,
$wapnil

When looking at SQL Server error logs, I noticed that the current error
log had grown to 1MB whereas most of the files are only a few KB.
QUESTION 1: Can I set the max size for an error log file? If so, how?
QUESTION 2: If not, is there a workaround?
Thanks

Does anyone have experience with truncating an expression like the Excel TRUNC?
For example in Excel, you might have something like =TRUNC(IF($AE11=0,1,X11/$AE11),5) which drops off a certain amount of the results after the decimal point. 87.5659321 becomes 87.565 instead of the result of a rounding.

Hi all,
This is a database on which there are continuous inserts and updates. Data is loaded into this database in bulk at regular intervals. I do not back up the transaction log. For these reasons, I have set the options, 'select into/bulk copy' and 'truncate log on checkpoint'. When the 'truncate log on checkpoint' option was not set, the log file would grow very huge and fill up the entire disk space(file growth is unlimited). But, even after the 'truncate log on checkpoint' option has been set, the log file does grow at times to fill up the entire disk. I assumed that since the 'truncate log on checkpoint' option was set, the inactive portion of the log would be truncated every 1 minute(ie, during every checkpoint). Could someone please explain the reason for this behaviour?
Thanks in advance,
Praveena

hello,
Daily, after a database backup done in the evening, around 3am we have a lot of flat files to integrate in tables and then process.
The question is : We want to free the space used by the transation log.
Then, we use "backup log with no_log" and/or "backup log with truncate_only"
We look at the size of the transaction log with "dbcc sqlperf( logspace )" but the 'Log space used %' stays the same.
Could you give us some informations or tips on this.
Thank you from Paris
Patrick

Hi everyone,
Although I truncate the log file and I have no pending transactions, its size does not shrink at all (it stays a 0.5 GB).
Does anyone know why or what can I do to solve this issue.
Thanks,

Recently I start working with SQL 6.5 server on NT4 (sp6)
Before me someone make abnormal reinstallation of this SQL server.
after that server need to be restarted every day
On the database edit window I have seen that Avaluable Log Space is 0
and in the course of working with device have seen that device definition
is erroneous. the path to file is different from the name of file,
i.e. in device defined (D:aaa03_log) and actually present file
(D:aaalog_03)
and as result every operation on device get the error.
I have change the name of the file to match the sql device definitions but
first this don't helped.
I have added new device and expanded the database log on it, but Avaluable Log Space remains 0.
After a number of restarts I noticed that old erroneous device is now
become visible and I can work with it, for instance expand it. But Avaluable Log Space remains 0 and in the sql monitor I also see that log occupied 100% of avaluable space.
May be transaction log located with data and I just can't see that ?
There is option on database edit window: Truncate transaction Log
and I want run it. The organisation don't interested in log. main thing is that the data will be safe.
Is it the right thing to do?
Tanks to everyone who can help
