How Can I Keep The Log From Filling Up?
Mar 21, 2008
I have a ton of data to load into a SQL 2005 database.
I just loaded a bunch of data for a number of tables using bcp, and the last table that my script loaded was an 8 million row table. The next table was a 12 million row table, and about 1 million rows into the bcp'ing a log full error was incurred. I have the batch size set to 10000 for all bcp commnads.
Here is the bcp command that failed:
"C:Program FilesMicrosoft SQL Server80ToolsBinncp" billing_data_repository..mtr_rdng_hrly_arc_t in mtr_rdng_hrly_arc_t.dat -c
-b10000 -Sxxxx -T
Here is the last part of the output from the bcp command:
...
10000 rows sent to SQL Server. Total sent: 970000
10000 rows sent to SQL Server. Total sent: 980000
10000 rows sent to SQL Server. Total sent: 990000
SQLState = 37000, NativeError = 9002
Error = [Microsoft][ODBC SQL Server Driver][SQL Server]The transaction log for database 'billing_data_repository' is full. To find out why space in the log cannot be reused, see the log_reuse_wait_desc column in sys.databases
BCP copy in failed
I thought that a commit was issued after every 10000 rows and that this would keep the log from filling up.
The log_reuse_wait_desc column in sys.databases is set to 'LOG_BACKUP' for the database being used.
Does a checkpoint need to be done more often?
Besides breaking up the 12 million row data file into something more manageable, does anyone have a solution?
How can I continue to use my same loading script, and keep the log from filling up?
Thank you.

I have a class that works fine using the SQLDataReader but when I try and duplicate the process using a Dataset instead of a SQLDataReader it returnsa a null value.
This is the code for the Method to return a datareader
publicSqlDataReader GetOrgID()
{
Singleton s1 = Singleton.Instance();
Guid uuid;
uuid = new Guid(s1.User_id);
SqlConnection con = new SqlConnection(conString);
string selectString = "Select OrgID From aspnet_OrgNames Where UserID = @UserID";
SqlCommand cmd = new SqlCommand(selectString, con);
cmd.Parameters.Add("@UserID", SqlDbType.UniqueIdentifier, 16).Value = uuid;
con.Open();
SqlDataReader dtr = cmd.ExecuteReader(CommandBehavior.CloseConnection);
return dtr;
This is the code trying to accomplish the same thing with a Dataset instead.
public DataSet organID(DataSet dataset)
{
Singleton s1 = Singleton.Instance();
Guid uuid;
uuid = new Guid(s1.User_id);
string queryString = "Select OrgID From aspnet_OrgNames Where UserID = @UserID";
SqlConnection con = new SqlConnection(conString);
SqlCommand cmd = new SqlCommand(queryString, con);
cmd.Parameters.Add("@UserID", SqlDbType.UniqueIdentifier, 16).Value = uuid;
SqlDataAdapter adapter = new SqlDataAdapter();
adapter.SelectCommand = cmd;
adapter.Fill(dataset);
return dataset;
}
Assume that the conString is set to a valid connection string. The Singlton passes the userid in from some code in the code behind page ...this functionality works as well.
So assume that the Guid is a valid entry..I should return a valid dataset but its null.
Additionally if I change the sql query to just be Select * From aspnet_OrgNames I still get a null value...I am assuming I am doing something wrong trying to fill the dataset.
Any help would be appreciated.

MS SQL Enterprise Server, SP5, running under version 6.5.
I have recently been having a problem with the TempDb database
filling up. I originally started the database at 250 Mb but
recently expanded it to 500 Mb.
My last check of the activity on the server during an event
such as this produced the following information.
- Approx. 300 connections to primarily 2 databases.
- 4 active connections:
Connection 1 -SELECT on database 1 with 13,000 records
and a record size of approx. 300 bytes.
Connection 2 -SELECT on database 1 with 13,000 records
and a record size of approx. 300 bytes.
Connection 3 -SELECT on database 2 with 550 records
and a record size of approx. 100 bytes.
Connection 4 -Replication subscriber set at 100 transactions.
My questions are:
1. What processes may cause the TempDb database to fill up?
2. What processes prevent the database from purging?
Any information would be greatly appreciated.

We are having continual problems with our transaction log filling up on one of our major applications.
Does anyone know of a way or tool to read the transaction log? We want to determine what is causing this problem.

Recently, we converted an Access database to SQL server 6.5. One of the processes that runs against the server is
missing a commit causing temporary stored procedures to fill up TEMPDB in the sysobjects table. The only way to
clear up TEMPDB is to stop and start SQL server when the database fills up. I wrote a quick and dirty stored
procedure to delete the affending rows out of the tempdb..sysobjects table, however, the database still registers as
full after the deletes.
Question:
does anyone know of a process/DBCC I can run against the tempdb..sysobjects table to regain the space in TEMPDB
without having to stop and restart SQL Server? I need a temporary solution while the programmer is debugging the
affending code.
Thanks!

hello,
I've got replication set up as a publisher subscriber, to basically sync a primary server with a
backup server. My distribution log keeps filling up, I've got a perf alert for now to truncate it
at 75% full for now, but why does it fill up? it's size is about 1.5 gig
My tran log for my database will also not remove about 500mb of data as well, is there any way to
see what is going on?
Thanks

I have a table that keeps track of click statistics for each one of my dealers.. I am creating graphs based on number of clicks that they received in a month, but if they didn't receive any in a certain month then it is left out..I know i have to do some outer join, but having trouble figuring exactly how..here is what i have:
select d.name, right(convert(varchar(25),s.stamp,105),7), isnull(count(1),0)
from tblstats s(nolock)
join tblDealer d(nolock)
on s.dealerid=d.id
where d.id=31
group by right(convert(varchar(25),s.stamp,105),7),d.name
order by 2 desc,3,1
this dealer had no clicks in april so this is what shows up:
joe blow 10-2004 567
joe blow 09-2004 269
joe blow 08-2004 66
joe blow 07-2004 30
joe blow 06-2004 8

What are typical programming bugs that would cause tempdb to fill up,
and how can I identify the offending statements through profiler?

We have a stored procedure that uses temp tables and must gather a lot of data. When we stress test this stored procedure, the tempdb transaction log fills up.
We tried using "Select Into" for our tables. That caused us not to write to the transaction log but it caused problems because it locked up sysobjects.
Is there some other way not to write to the transaction log?

I have a database that I am splitting the data using odd account numbers and even account numbers. The odd acct numbers in one database and the even in the other database.
This database is very large. The problem is when I run the delete statements
it is going to fill up the log files. Can I turn on the "Simple" mode on the database while I am deleteing the data. Will this cause a problem? Then can I turn back on the 'Full' mode when I have finished?
Has anyone ever done this and so how did it work. Or better yet is it possible?
Thanks,
Dianne

Hello,
I am new to SQL Server and learning lots very quickly! I am experienced at building databases in Access and using VBA in Access and Excel.
I have a time series of 1440 records that may have some gaps in it. I need to check the time series for gaps and then fill these or reject the time series.
The criteria for accepting and rejecting is a user defined number of time steps from 1 to 10. For example, if the user sets the maximum gap as 5 time steps and a gap has 5 or less then I simply want to lineraly interpolate betwen the two timesteps bounding the gap. If the gap is 6 time steps then I will reject the timeseries.
I have searched the BOL and MSDN for SQL Server and think there must be a solution using the PredictTimeSeries in DMX, but not quite sure if I can do this. I may be better off simply passing through the time series as a recordset and processing as I would have done in Access...(I am reluctant to do this as I have of the order 100 * 5 * 365 time series and growng by 100 each day and fear it will take quite some time...)
Can anyone help me by pointing me in the right direction please?
Unless there is a way of using PredictTimeSeries on its own, I think the solution is:
Identify if a record is the a valid one or part of a gap (ie missing values).
Identify the longest gap and reject or process data on this value.
Identify if a record preceedes or succeeds a gap.
For each gap fill it using a linear interpolation.
Thanks,
Alan.

Hello,
In my application I am using Identity columns. When some rows are deleted from table, This identity values are not filling the gap. I mean My current identity is 5. That means 1 to 5 rows sequentially i inserted. If I am deleting 3rd and 4th rows, next identity will still continue with 6. So is there any method to fill the gap between rows

hi all!
I have 2 instances that communicate via service broker.
The conversations are only one way from initiator server1 db to target server2 db.
I also reuse dialog id's in BEGIN DIALOG @dlgId
i save @dlgId from the first run into a table and then retreive it for each message send
since the messages are constant i don't close the dialog at the target for each message.
i'm just wodering why do both sys.transmission_queue and sys.conversation_endpoints get a row
for each message i send but the transmission_status in sys.transmission_queue is emtpy.
also each conversation_handle and conversation_id is different for each row and
only one row in each sys table has the same conversation_handle as my saved @dlgId.
just wondering what is going on.
this code is done on the initiator
DECLARE @dlgId UNIQUEIDENTIFIER
-- each database has one dialog id
SELECT @dlgId = DialogId
FROM dbo.Dialogs
WHERE DbId = DB_ID()
-- Begin the dialog, either with existing or new Id
BEGIN DIALOG @dlgId
FROM SERVICE [//DataSender] -- service on initiator server
TO SERVICE '//DataWriter', -- service on target server
-- Target's Service Broker Id
'83382A22-2830-4B25-B067-15AAC255EB03'
ON CONTRACT [//Contract1]
WITH ENCRYPTION = OFF;
-- Send data
;SEND ON CONVERSATION @dlgId
MESSAGE TYPE [//Message1] (@msg)
Thanx,

I am having an issue with the transaction growing uncontrolled and filling up the disk. I suspect that transactions are structured incorrectly between the web application that is monitoring a queue and the SQL that is executing the WAITFOR RECEIVE. This method is receiving large binary objects, so thats the reason for the arguments to the reader. Also, even though its not the suggested way, we commit everytime through to prevent the queue from disabling (which it was doing when we would ROLLBACK - we don't really care if the message is bad, we just want to log it and wait for the next one).
The basic structure is this, which is executed on a separate thread. Am I missing something that could be causing transactions to get into a state where the log grows uncontrollably? Is there a problem with the loop? Should I be doing a ROLLBACK when there is nothing to receive (this is a low volume queue, so it may not receive a message for a few minutes or more)? If so, where should I be doing this?
private void MonitorUpdateQueue()
{
const string _sqlEndDialog = @"END CONVERSATION @conversationHandle";
const string _errorMessageType = @"http://schemas.microsoft.com/SQL/ServiceBroker/Error";
const string _endDialogMessageType = @"http://schemas.microsoft.com/SQL/ServiceBroker/EndDialog";
using (_ssbConnection)
{
if (_ssbConnection == null) _ssbConnection = new SqlConnection();
using (_monitorQueueCommand =
new SqlCommand("asp_ProcessMessage", _ssbConnection))
{
_monitorQueueCommand.CommandType = CommandType.StoredProcedure;
_monitorQueueCommand.CommandTimeout = 0;
while (true)
{
SqlDataReader reader = null;
Guid conversationHandle = Guid.Empty;
Byte[] payloadBytes = { 0 };
try
{
if (_ssbConnection.State == ConnectionState.Closed)
{
_ssbConnection.ConnectionString = _ssbConnectionString;
_ssbConnection.Open();
}
Byte[] latestFullUpdate = null;
_monitorQueueCommand.Transaction = _ssbConnection.BeginTransaction(IsolationLevel.Serializable);
if (_monitorQueueCommand.Transaction != null)
{
reader = _monitorQueueCommand.ExecuteReader(CommandBehavior.SequentialAccess);
if (reader != null)
{
XmlDocument updateMessage = new XmlDocument();
while (reader.Read())
{
conversationHandle = reader.GetGuid(0);
string messageType = reader.GetString(1);
payloadBytes = reader.GetSqlBytes(2).Value;
if (messageType == _endDialogMessageType || messageType == _errorMessageType)
{
SqlCommand cmdEndDialog = new SqlCommand(_sqlEndDialog, _ssbConnection, _monitorQueueCommand.Transaction);
cmdEndDialog.Parameters.AddWithValue("@conversationHandle",
conversationHandle);
cmdEndDialog.ExecuteNonQuery();
}
else
{
if (payloadBytes.Length > 0)
{
ProcessUpdateQueue(updateMessage);
}
}
}
reader.Close();
}
_monitorQueueCommand.Transaction.Commit();
}
}
catch (Exception ex)
{
if (_monitorQueueCommand.Transaction != null && _monitorQueueCommand.Transaction.Connection != null)
{
// Dequeue the bad message and ends the conversation
SqlCommand cmdQuarantineMessage = new SqlCommand("usp_FailMessage", _ssbConnection, _monitorQueueCommand.Transaction);
cmdQuarantineMessage.CommandType = CommandType.StoredProcedure;
cmdQuarantineMessage.ExecuteNonQuery();
if (reader != null && !reader.IsClosed) reader.Close();
if (_monitorQueueCommand.Transaction != null) _monitorQueueCommand.Transaction.Commit();
}
log.Error("Error monitoring queue.", ex);

finally

if (reader != null && !reader.IsClosed) reader.Close();
if (_monitorQueueCommand.Transaction != null)
{
_monitorQueueCommand.Transaction = null;
}
}
}
}
}
}
The stored procedure that is monitoring looks like this:
CREATE PROCEDURE [dbo].[asp_ProcessMessage]
AS
BEGIN
WAITFOR ( RECEIVE TOP ( 1 ) conversation_handle, message_type_name, message_body
FROM [MyQueue] ) ;

Hi,
I've been having problems with my tempdb filling up, and causing all databases on the server to stop functioning properly. I've been removing alot of data lately (millions of rows), and I think this is the reason why my tempdb log is going thru an unusual load.
Whats the best way to make sure the tempdb doesnt fill up causing me major problems? I had temporarily turned off backups while I was having a new HD put in. Am I right in thinking that when a DB is backed up, the tempdb log is reduced in size? Should maintaining a daily backup solution help keep things under control ?
Thanks very much for any tips!

Hi,
I always get a "ConstraintException" error when trying, at beginning of application, to run following statement (within "Form1_Load" routine called by "this->Load" EventHandler):
"this->TauxTaxeTableAdapter->FillByPays(this->TauxTaxeDataSet->TauxTaxe,Cur_GrdView_SlPays);"
Also curiously if, while application is still running, I invoke again that same statement by means of a pushbutton clickevent, everything is running smootly without error... Looks to me that it is bugging only when running the first time...
Within Dataset, I tried to see what constraint could give me such trouble. Here is the only constraint I could find:
"this->Constraints->Add((gcnew System::Data::UniqueConstraint(L"Constraint1", gcnew cli::array< System::Data::DataColumn^ >(2) {this->columnPays, this->columnProvince_Etat}, true)));"
I then tried to find within "TauxTaxe" table if there could be any trace of records where "Pays" and "Province_Etat" columns would show any null value as well as any duplicate key values but there wasn't any...
Any place I should start to look for? BTW, I'm using a SQL Express database.
Thanks for your help,
Stéphane

Hi,
I have the following table :
Code Block
Create table #Customers (custid int,name nvarchar(20),age int, st_code int,
citycode int, internalid int,type int,oldcustid int)
Insert into #Customers values(101,'Aron',23,1,1,12,1,0);
Insert into #Customers values(102,'Cathy',28,1,1,13,1,0);
Insert into #Customers values(103,'Zarog',33,1,1,14,1,0);
Insert into #Customers values(104,'Michale',25,1,2,12,1,0);
Insert into #Customers values(105,'Linda',43,1,2,13,1,0);
Insert into #Customers values(106,'Burt',53,1,2,14,1,0);
If you observe, the rows are unique based on the internalid per st_code,per city_code
Problem :
Now the user inserts another row but this time he passes only the following :
Insert into #Customer values(120,'AronNew',null,1,1,12,null,null) -
Note he doesnt pass the age or the type
I want that when he passes this row, i match up this row with the existing row based on st_code,citycode and internalid and then update the new row with the missing values(only columns with null) that were there in the existing row
OUTPUT
120,'AronNew',23,1,1,12,1,0
How could I write the query for this?
thanks.

is called and runs and returns results... But a dataset with one table
and the above msg is returned...

Hi All,
I'm hoping somebody can help me with this as it is driving me mad. I've created a stored procedure which returns Employee information recordset when the windows username is passed to it as a parameter. I want to then store this information in Session variables so content can be filtered depending on employee status, but when I execute my code no records are returned. I know for a fact that the stored procedure works because I bound it sqldatasource and displayed results from it in a Datalist and tested it in sql server. My code is as follows can anybody see any problems with it, in runs through fine with but when I try a read a field from the datareader in says there is no data to read.
Dim CurrentUser As String, Pos1 As Int16, EmployeeId As Int32
Dim cn As New System.Data.SqlClient.SqlConnection
Dim param As New System.Data.SqlClient.SqlParameter
Dim reader As System.Data.SqlClient.SqlDataReader
Dim cmd As New System.Data.SqlClient.SqlCommand
CurrentUser = CStr(User.Identity.Name)
Pos1 = InStr(CurrentUser, "") + 1
CurrentUser = Mid(CurrentUser, Pos1)
Session("User") = CurrentUser
Session("CID") = Nothing
cn.ConnectionString = "Data Source=LAPTOP-4SQLEXPRESS;Initial Catalog=SCMdb;Integrated Security=True"
cn.Open()
cmd.Connection = cn
cmd.CommandText = "CurrentUser"
cmd.CommandType = CommandType.StoredProcedure
param = cmd.CreateParameter
param.ParameterName = "@UserName"
param.SqlDbType = SqlDbType.VarChar
param.Value = CurrentUser
cmd.Parameters.Add(param)
reader = cmd.ExecuteReader(CommandBehavior.CloseConnection)
EmployeeId = reader.Item("EmployeeID")
reader.Close()
Any help would be much appricated this is driving me mad.
Thank You
Shaft

Hi
I am currently working on an application that uses a stored procedure to retrieve data from a database and then display it in a web page. My problem is that some of the data in the database will be images, I am currently putting in test data to test my code/procedures my problem is how do I put in test data for images, when I am finished I am going to add an admin section that will allow me to add images that way but how do I go about adding them to the database until then? I have set the field to the image data type but have no idea how to relate this to an image on my server?
Thanks, Adam

Does anyone know what would cause SQL MAil or Exchange to save all messages and some 1K att*.txt files to the WINNT directory? This is filling up the hard drive on a production system so it's kind of urgent.
Thanks!

I have phrased this question here once before but no one could answer it, so please let me know if you think you know what the problem is.
I have a Test Environment on Server2 restored from the production environment on Server1. Production is publishing to a subscriber on Server3. The problem is that even though I have truncate on checkpoint = TRUE set for the Test environment, the log fills up (all the way, not even truncate transaction with no_log fixes it).
The log size is 750MB, with a data portion of about 3GB. Is this somehow related to the fact that SQL Server still thinks the tables in the test environment are marked for replication? I have noticed it believes this becuase I am not allowed to drop tables on Test, even though Test is not even set up as a publishing database.
Other information:
1) The recovery interval on Server2 is 3 minutes.
2) I am frustrated
Thanks in advance.

I have a database [CarlosDB] that currently has it's .MDF on E: and I need to move the x2 .NDF data files off C: to E:data using a single T-SQL statement:
Code:
database_id file_id db_name disk_path status size read_only
----------- ----------- --------------------------------------------------------------------------------------------------------------------------------
7 1 CarlosDB E:dataCarlosDB.mdf ONLINE 384 0
7 2 CarlosDB_log L:logsCarlosDB_log.ldf ONLINE 128 0
7 3 CarlosDB_2 C:sqlCarlosDB_2.ndf ONLINE 128 0
7 4 CarlosDB_3 C:sqlCarlosDB_3.ndf ONLINE 128 0
(4 row(s) affected)
Looking at the file configuration above, what would be the most logical way as a DBA / SQL Server 2014 Std to move the NDF files to live w/ the MDF file using:
Code:
EXEC master.dbo.xp_cmdshell 'copy c:sqlCarlosDB_2.ndf e:dataCarlosDB_2/ndf'...
but cleanly using a single T-SQL statement? properly formatting a single T-SQL query to use the xp_cmdshell system stored procedure.

Hi! I'm wondering why is my sys.conversation_endpoints table inserting a new row for each message i send even when i reuse conversations?
when i send the first message i get the first row in the sys.conversation_endpoints with a uniqueidentifier for the conversation_handle. this uniqueidentifier is then saved in the table which i query the next time i send a message to reuse the dialog conversation.
But even though it looks like the uniqueidentifier is reused i still get a new row for every message i send with a different conversation_handle?
this happens in both target and initator db.
I've tried to understand this by i don't.
Also for the moment i don't end conversations. But as i understand it this shouldn't matter.
Also the message successfully arives to the target and sys.transmission_queue is empty in both databases.
Neither queues have any error messages in them.
Thanx
