How To Flush The Buffer To Trc File

May 7, 2004

I want to trace the user logins by using a stored procedure. This script (sp_login_trace) is created by the SQL Profiler tool. (Once this procedure works well, I will use sp_procoption to run it automatically everytime the SQL Server startup.)

After I successfully created sp_login_trace, I run it (exec sp_login_trace). The trace process is started and TraceID is 1. (I use select * from ::fn_trace_getinfo(default) to verify it). However the file size of login_trace.trc is always 0 even after I use Query Ananlysis or Eneterprise manager to let some users to login into the SQL Server instance. (when I use SQL Profiler to start a trace, the trace file size will increase along with users continaully login in). At that time if I use SQL Profiler to open the login_trace.trc file, the system will give me an error message: No data since Empty File.

After I stop and delete the trace process, I find that the file size of login_trace.trc becomes 128K and I can see the login records caught by sp_login_trace if I use SQL Profiler to open this file again.

How can I flush the buffer to trc file frequently without need of stopping trace process?

Thanks for helps in advance.

How To Flush Data Stored In SSIS Buffer

Aug 2, 2007

Hi,

I am working on my own data flow source component. Here is a fragment of this component code:


public override void PrimeOutput(int outputs, int[] outputIDs, PipelineBuffer[] buffers) { PipelineBuffer selectedBuffer = buffers[0]; string message; while ((message = GetMessage()) != null) { selectedBuffer.AddRow(); selectedBuffer.SetString(0, message); // how to flush data here? } selectedBuffer.SetEndOfRowset(); } private string GetMessage() { // we are retrieving some message here, this is a long-term process }

When a new row is added by this component to the buffer then this row is not immediately available to the next component in data flow. It is possible to configure SSIS in that way that each row is immediately sent to the next data flow component? If no also please inform me about that.

Thanks,
Rafal

Error: The Buffer Manager Failed To Create A New Buffer Type

Apr 28, 2006

Hi

I have a master package that executes a series of sub packages run from a SQL Agent job. One of those sub packages has been stable for a week, running at least once per day, but it just failed despite having been run once already today with the same set of input data.

There were a series of errors showing in the event log for the Execute Package Task starting with "Buffer Type 15 had a size of 0 bytes.", then "The buffer manager failed to create a new buffer type.", then "The Data Flow task cannot register a buffer type. The type had 32 columns and was for execution tree 3.", then "The layout failed validation." and finally "Error 0xC0012050 while loading package file "C:[Package].dtsx". Package failed validation from the ExecutePackage task. The package cannot run.".

SQLIS.com reports the constant for the error code as DTS_E_REMOTEPACKAGEVALIDATION ( http://wiki.sqlis.com/default.aspx/SQLISWiki/0xC0012050.html ).

I then ran the package on my dev machine in BIDS and it worked fine, so I re-ran the job on the server and this time that package executed ok, but another one fell over but did not put anything in the event log.

Does any one have any idea what happened?

TIA . . . Ed

Warning - Kept Reference To Buffer - What Can Be Done About These Buffer Warnings?

Mar 6, 2008

Good day everyone,

I'm experiencing a completely random warning from any given row count component within any given data flow task. It occurs sporadically. Whilst distracting, I don't see any adverse effects to the data after the packages complete. Can someone weigh in on this warning and let me know if it is indeed benign or what I maybe able to do to fix it?

Here's the warning:

"A call to the ProcessInput method for input 75997 on component "CNT Rows sent for STG table" (75995) unexpectedly kept a reference to the buffer it was passed. The refcount on that buffer was 4 before the call, and 5 after the call returned."

Thanks,

Langston

OLE DB SOURCE Failure - The Buffer Manager Could Not Get A Temporary File Name. The Call To GetTempFileName Failed.

Mar 14, 2008



Hello,

I am running Data Flow and it fails on the OLE DB Source. Source has 13 fields in the table. One of the field is text (blob, comma delimited string - can be big) which creates a problem. This data flow runs fine with smaller amout of data. In this case Source table has 200,000 records.

The error I am getting is:

Any ideas?

Thanks.

T-SQL PRINT Flush?

Aug 21, 2004

I have a long running (48 hour+) stored proc. I've added PRINT statements that print "1%", "2%", etc to provide progress so I can get a ballpark idea of how far along the process is. I ran the stored proc and realized that this won't work. I don't see the output of the print statements until the stored proc is completed. I'm running this from Query Analyzer (SQL Server 2000 SP3a).

For example, the following will wait ten seconds and then print both statements; it doesn't print one then wait, then print the other. Is there any flush command to make the print statements take effect immediately?

PRINT 'before'
WAITFOR DELAY '000:00:10'
PRINT 'after'

How Do I Write Multiple Pipeline Buffer To Multiple Targets Based On A Calculated Value In The Pipeline Buffer

Apr 6, 2007

The scenario is as follows: I have a source with many rows. Each row has a column called max_qty_value. I need to perform a calculation using another column called qty. This calculation is something similar to dividing qty/(ceiling) max_qty_value. Once I have that number I need to write an additional duplicate row for each value from the prior calculation performed. For example, 15/4 = 4. I need to write 4 rows to the same target table as in line information for a purchase order.



The multicast transform appears to only support fixed and/or predetermined outputs. How do I design this logic in SSIS to write out dynamic number of rows to a target table.



Any ideas would be greatly appreciated.



thanks

Buffer Overflow In DTS

Apr 3, 2001

I'm having a problem importing a text file into a SQL db using DTS. I have to transform some of the data that is being imported so I think Bulk import is out of the question.

Everything works fine until a hit a row that contains more than 255 characters in one cell. Once it encounters that row, it fires this error:

"Error at source for row number 9.Errors encountered so far in this task :1
General Error: -2147217887(80040E21)
Data for Source Column 3('Col3') is too large for the specified buffer size."

I found a entry in the MS KnowledgeBase that addresses the symptom but the workaround doesn't fix it:

http://support.microsoft.com/support/kb/articles/Q281/5/17.ASP?LN=EN-US&SD=tech&FR=0&qry=DTS%20buffer&rnk=3&src=DHCS_MSPSS_tech_SRCH&SPR=SQL

Anyone have any ideas.....

Buffer Cache

Sep 30, 1999

Help, have recently upgraded from 6.5 to 7.0 and have come across a problem with performance. The problem appears to relate to the buffer cache being flushed, the buffer cache hit ratio drops from 98% to 0% in a matter of a second. It then very slowly grows, then is flushed again, then increase slowly upto 30%.

Does any one have any ideas as to what would flush the buffer cache?

Any comments would be much appreciated - cheers

'Msg 845, Sev 17: Time-out occurred while waiting for buffer latch type 3 for page (1:8200), database ID 2. [SQLSTATE 42000]'.

Can someone tell me what's going on? This new server is supposed to be much more powerful than the old server.

What value should I monitor for the new server to prevent this timeout?

The Buffer Is Insufficient

Aug 22, 2007

Hi all,

I have a strange problem that I need to solve as soon as possible.
I have created two CLR UDTs called point and point_list. Each record of a point_list consists of a list of points. I created a CLR stored procedure which reads some raw data and updates the point_list records.
When I execute the stored procedure the following error appears :

System.Data.SqlTypes.SqlTypeException: The buffer is insufficient. Read or write operation failed.
System.Data.SqlTypes.SqlTypeException:
at System.Data.SqlTypes.SqlBytes.Write(Int64 offset, Byte[] buffer, Int32 offsetInBuffer, Int32 count)
at System.Data.SqlTypes.StreamOnSqlBytes.Write(Byte[] buffer, Int32 offset, Int32 count)
at System.IO.BinaryWriter.Write(Char ch) etc ...


Does anybody know what should I do ?
Thanks!

I am trying to set a decimal value to the pipelinecolumn buffer, but it doesnt get set, and the value is NULL.

Here is the portion of the code of what I am trying to do:

if (columnInfos[x].colName.EndsWith("_CRC"))

int a;

a_cmp tst = new a_cmp();

a= tst.a_crc32(inputbufferstream); this function returns a integer value



buffer.SetDecimal(colInfo.bufferColumnIndex, Convert.ToDecimal(a));

Can't Get At First Row Of Input Buffer...why?!

Aug 8, 2007

Hi

A script component receives some input. But I just can't get at the first row??

Basically, if i use the NextRow method in the in the Do statement, then it advances the row collection to the second row before it gets into the code inside the loop?? BUT, if I use the EndOfRowset property to define my loop then I get an error:

[PipelineBuffer has encountered an invalid row index value]

I'm guessing this means...I have to call NextRow before i access the data in the collection? But thats retarted because then I miss the first row?? what? What am I missing??

This is the code which works but I miss the first row:

Public Overrides Sub Input0_ProcessInputRow(ByVal Row As Input0Buffer)
Dim strConcept As String

Do While Row.NextRow()


strConcept = Row.concept

updateDb(strConcept)

Loop
End Sub

This is the code which throws the invalid row index error:

Public Overrides Sub Input0_ProcessInputRow(ByVal Row As Input0Buffer)
Dim strConcept As String

Do While Not Row.EndOfRowSet()


strConcept = Row.concept

updateDb(strConcept)

Row.NextRow()

Loop
End Sub

I've put some try catches in there an the error happens on the line which calls Row.concept....?

Can anyone help, it must be something I'm messing up

thanks!!

Buffer Exception

May 29, 2006

When running a package created on my local machine i get no errors at all but when i try to run the same package on the server i get an error specifying Microsoft.SqlServer.Dts.Pipeline.DoesNotFitBufferException: The value is too large to fit in the column data area of the buffer.

I have tried changing the defaultbuffersize of the data flow task but this makes no difference. I think that a buffer size for a particular column is being exceed but i cannot find anywhere to set this property.

Has anyone else struck this error?

Why Are Buffer Locked...

Oct 22, 2007

We had a package fail when trying to get 3 buffers. I also saw another message saying "18430 buffers were considered and 18430 were locked. "

1. Why are buffers locked in SSIS
2. How can i reduce the number of locked buffers.

This one in question was a very large lookup.

Thanks

Too Large For The Specified Buffer Size

May 24, 2006

Hi

I've been searching this site and the Web for info on an error message I get when importing from Access 2003 into SQL Server 2000.

'Data for Source Column 3('Col3') is too large for the specified buffer size'

A memo field in Access is larger than 255.

I have followed advice about putting the field to the first column. This doesn't work - the error just returns the new column number. In fact, I've tried just importing the first column - no good.

I am wary about making Registry changes as comments on the Web say this doesn't work either.

Does anybody have the solution for this.

Paul

SQL 2012 :: Log Buffer Waits

Sep 1, 2015

Last Sunday on our Primary server I saw some blocking and the First spid that blocked everything was waiting on LogBuffer wait. At that time the server was not running hot and our DB is on SSD's. There was no memory pressure(1 TB of memory on the server) It is strange why we should get LogBuffer wait when we are running on the fastest disks possible and there was not much action going on the DB.
