MS SQL Server :: Buffer Problem

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

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

Buffer Exception
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?

No Buffer Space Available
First this isn't really related to integration services, but it seemed the best place to ask.

I have already done some research online, but I'm having a hard time nailing down my problem. It seems that this usually relates to TCP stack overflow, usually tied to JDBC, based on my research. However...

I am inserting several tables in sequence from a linked server (connecting to a PostgreSQL database) and I can run the process without a problem usually. Then I got the following error message repeated for each table yesterday afternoon.

OLE DB provider "MSDASQL" for linked server "[LinkedServerName]" returned message "[Microsoft][ODBC Driver Manager] Driver's SQLSetConnectAttr failed".

OLE DB provider "MSDASQL" for linked server "[LinkedServerName" returned message "could not connect to server: No buffer space available (0x00002747/10055)

Is the server running on host "[LinkedServerHost]" and accepting
TCP/IP connections on port 5432?

I don't know if it was a cause or just an effect also. Someone else was running a new Reporting Services report that may have been bloated in design.

Just wanted to see if anyone has dealt with this before and has any insight.

Thanks,
Hugh

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

The Buffer Is Insufficient
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:

Too Large For The Specified Buffer Size
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.

How To Flush The Buffer To Trc File
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.

Output Buffer Remove Row?
I am using a script component to create the output buffer dynamically. I use the Outputbuffer.AddRow() call. I then set all the fields I want, and its added to the output and later inserted into the database. If a field value fails it causes an error, but the record is partially inserted upto the point where the set field command caused the error. So if I set 10 fields, and it fails on field 5 it inserts data for the 5 fields that worked and nulls into the others.

As a result I have a try catch clause, and if it fails I want to cancell the addition of the new row. Is there a command like RemoveRow(), rollback, etc that can be used to not insert the record in error?

Sample code..

Try

PaymentOutputBuffer.AddRow()

PaymentOutputBuffer.Sequence = pi + 1

PaymentOutputBuffer.RecordID = Row.RecordID

PaymentOutputBuffer.PaymentMethod = PaymentArray(pi)

Catch e As Exception

PaymentErrorOutputBuffer.removecurrentrow(??)

End Try

Overflow The Disk I/O Buffer
Hello,

I am getting "overflow the disk I/O buffer" in my SSIS, and what's weird is that when I construct the same SSIS in a new package, it works perfectly. I almost want to believe that it could be a bug. Some days when I import the files, it works fine, but some days it errors out with this error on the last column. Is there some setting with CR/LF or LF that I have to pay attention to avoid this type of random error?

Can't Clean Buffer Cache
Hi,

My problem is that I cannot completely clean buffer cache on SQL Server 2005 version 9.00.2047.00 (probably SP1).

Right after I run DBCC DROPCLEANBUFFERS in the context of my database (this is development server, and so far I am only the one who is working with a particular database), I run a script that quetries sys.dm_os_buffer_descriptors view also from the context of my database to make sure that the buffer cache is really clean. However it shows large number of entries totalling 42 MB.

I ran both DBCC an the script in the past too, and it always showed nothing in the results, that means that buffers were really clean. The reason why I am running this is for benchmarking of existing and new application.

Does anybody have any idea, suggestions, how to troubleshoot this issue ? I already closed all connections to this database, but rebooting the server is not an option since other people are also working on it.

Difference In Command Buffer Between 32-bit And 64-bit
We have a SQL2005 32-bit server in development and a 64-bit SQL2005 server in production. Both are running SP2. I have an update statement that is actually being called from an ASP page, but if I paste the query into Query Analyzer I see the same problem, which is:

If the command is 250 characters or longer, I get an error against the 32-bit server. It succeeds against the production server. The command is an update statement and, because of the way it is generated, there can be numerous embedded spaces between keywords, columns names, etc. For instance, this code will fail against 32-bit but succeed against 64-bit:

UPDATE ourTable001SET vchReturnAddress = 'ABCDEF', vchEntity01Name = 'ABCDEF', vchAddress1 = 'ABCDEF', vchAddress2 = 'ABCDEF, vchCity = 'ABCDEF', chState = 'MA'WHERE recordID = 47 AND vchEntity01ID = '0009115'

All I have to do is remove one space or newline and it will work. Other than the bit-ness of the servers, the only difference is that the dev server was patched with the original SP2 and then hotfixed (9.0.3050 is the reported version) while the production server used the updated SP2 (9.0.3042).

The error returned is: String or binary data would be truncated
so I'm guessing the last character is getting lost. Using SQL Profiler, everything is there, so I don't think it is a client-side issue.

Ideas?

Error 845: Buffer Latch Timeout
More of an FYI in case anyone has run into this problem...We were running into the infamous "timeout on buffer latch type 3" error andwas caused by the autogrow in tempdb. Apparently when SQL Server is gettinghit pretty hard and tempdb is taking a timeout to auto-grow, SQL servercraps its pants and times-out. This combined with the fact that tempdbshrinks down to its last set size after a restart, you'll hit this errorpretty regularly after a SQL Server bounce. (If tempdb auto-grow from a set1GB to 10GB, after the restart tempdb will be 1GB again. - Just how gay isthat?) Anyway, we just manually set tempdb to a respectable level to resolvethe problem.

ProcessInput Method Kept A Reference To The Buffer
Hi

I have written a custom data flow component that counts the rows coming through the pipeline and adds the counts to an object stored in a package variable.

The component sometimes generates warnings with the following message - "A call to the ProcessInput method for input 358 on component "<Component Name>" (354) 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.".

The component is used several times throughout ~60 packages. It does not always occur on the same instance, or even in the same package, from one occasion to another. When all the packages are executed (from a master package - some in parallel and some in series) the warning is generated several times (around 10), but the warning is not generated at all when the packages are executed individually from BIDS. The values of the refcounts vary from message to message, but the difference is always 1 more after the call than it was before. The server has SP1 and the hotfix package installed, but the warning was being generated before SP1.

I do not understand what could be keeping a reference to the buffer. The ProcessInput method is very basic:

public override void ProcessInput(int inputID, PipelineBuffer buffer)
{
try
{
  if (!buffer.EndOfRowset)
                {
                    totalRowCount += buffer.RowCount;
                }
}
catch (Exception ex)
{
  bool cancel = false;
                ComponentMetaData.FireError(0, ComponentMetaData.Name, ex.Message, string.Empty, 0, out cancel);
                throw new Exception("Could not process input.", ex);
}
}

Does anyone have any idea what could be causing this, or ideas for things I should be investigating?

Buffer Problems On Data Flow
From what I remember there were a couple problems in the ctp's with buffer allocation errors. We seem to be seeing a similar error on 2005 x64 when we create a large number of sources and destinations within one dataflow task (something more than around 15 of each). Basically all we are doing is copying tables from one db to another. The computer will lock after about a million rows with a ton of the following messages:

The buffer manager detected that the system was low on virtual memory, but was unable to swap out any buffers. 124 buffers were considered and 124 were locked. Either not enough memory is available to the pipeline because not enough is installed, other processes are using it, or too many buffers are locked.

We have 4 gigs of ram on that server so I'm not sure what's wrong with this.

OLEDB DB2 Destination Out Of Buffer Type 0 And 3

I have a dataflow in my SSIS Package that is supposed to transfer over all the rows from a SQL server table. I am selecting columns from the SQL table and there is a total of 1603 rows. I am only getting 354 rows in the DB2 destination table. I have turned on SQL logging and specifically the BufferSizeTuning option for this dataflow. in the Sysdtslog90 table I see messages about the "Rows in buffer type 0 would cause a buffer size greater than the configured maximum. There will only be 1249 rows in buffers of this type" and "Rows in buffer type 3 would cause a buffer size greater than the configured maximum. There will only be 1251 rows in buffers of this type"

I have the following set in the Dataflow properties.
DefaultMaxBufferRows = 5000
DefaultBufferSize = 10485760

The server is windows server 2003 x64, SQL Server 2005 sp1 resides on this server where the SSIS packages are running also. 12gb of ram.

Any suggestions how i can get all the rows transferred, what is Buffer Type 0 and 3? this doesnt seem like a lot of rows (1603 total) to hit a DB2 destination with.

Any settings I would need to check in the Connection Manager? I am using Native OLE DBMicrosoft OLE DB Provider for DB2.

Hello all,

I'm writing a custom component similar to the "Derived Column" transformation, in which a value of some input column is "decoded" into an output column.

Here's the code:

Code Snippet

public override void ProcessInput(int inputID, PipelineBuffer buffer){

//TODO

setupTraceListener();

IDTSOutput90 outp = ComponentMetaData.OutputCollection["DecodeOutput"];

int outId = outp.ID;

int errorOut = -1;

IDTSInput90 inp = ComponentMetaData.InputCollection.GetObjectByID(inputID);
if( ComponentMetaData.OutputCollection.Count > 1){errorOut = ComponentMetaData.OutputCollection["DecodeErrors"].ID;

}

string sourceValue;

if(!buffer.EndOfRowset){
while(buffer.NextRow()){

if(!buffer.IsNull(inputColumnBufferIndex)){

switch(inp.InputColumnCollection[0].DataType){

case DataType.DT_WSTR:

sourceValue = buffer.GetString(this.inputColumnBufferIndex);

break;

case DataType.DT_I4:

sourceValue = buffer.GetInt32(this.inputColumnBufferIndex).ToString();

break;

default: throw new Exception("Invalid Data Type!");

}

sourceValue = sourceValue.Trim();

try{

object decodedValueObj = this.mappings[sourceValue];

if(decodedValueObj == null){

throw new Exception("No mapping!");

}

string decodedValue = decodedValueObj.ToString();

switch(outp.OutputColumnCollection[0].DataType){

case DataType.DT_WSTR:

buffer.SetString(this.outputColumnBufferIndex, decodedValue);

break;

case DataType.DT_I4:

buffer.SetInt32(this.outputColumnBufferIndex, int.Parse(decodedValue));

break;

default:

throw new IOException("Invalid Data Type!");

}

buffer.DirectRow(outId);

}catch(IOException fake){

throw fake;

}catch(Exception e){

redirectOrFail(inp, errorOut, outId, buffer, e);

}

}else{

redirectOrFail(inp,errorOut,outId,buffer,new Exception("Null values cannot be mapped"));

}

}

}

}

mappings is a hash map filled in PreExecute by accessing a database, outputColumnBufferIndex is calculated like this:

Code Snippet
IDTSInput90 input = ComponentMetaData.InputCollection[0];
IDTSOutput90 output = ComponentMetaData.OutputCollection["DecodeOutput"];
IDTSInputColumn90 inputColumn = input.InputColumnCollection[0];
IDTSOutputColumn90 outputColumn = output.OutputColumnCollection[0];
this.inputColumnBufferIndex =
BufferManager.FindColumnByLineageID(input.Buffer, inputColumn.LineageID);
this.outputColumnBufferIndex =
BufferManager.FindColumnByLineageID(input.Buffer, outputColumn.LineageID);

I've highlighted the parts that interest me, I've been testing the component thoroughly and it is getting the input data and mappings right, but it won't write the Decoded value to the given column and leaves it empty, even though the decodedValue variable is not null.

I'm guessing theres a problem when I call buffer.SetString() but I haven't the slightest idea of what that could be.

Any help would be greatly appreciated!

Column Overflowed The Disk I/O Buffer
Hi everyone,
I am using SSIS, and I got the folowing error, I am loading several CSV files in a OLE DB, Becasuse the file is finishing and the tak dont realize of the anormal termination, making an overflow.
So basically what i want is to control the anormal ending of the csv file.
please can anyone help me ???

[DTS.Pipeline] Error: Column Data for Column "Client" overflowed the disk I/O buffer
[DTS.Pipeline] Error: The PrimeOutput method on component "Client Source" (1) returned error code 0xC0202092. The component returned a failure code when the pipeline engine called PrimeOutput(). The meaning of the failure code is defined by the component, but the error is fatal and the pipeline stopped executing.

[DTS.Pipeline] Error: Thread "SourceThread0" has exited with error code 0xC0047038.

[DTS.Pipeline] Error: Thread "WorkThread0" received a shutdown signal and is terminating. The user requested a shutdown, or an error in another thread is causing the pipeline to shutdown.

[DTS.Pipeline] Error: Thread "WorkThread0" has exited with error code 0xC0047039.

Thanks a lot

DTS Buffer Times Out When Inserting To Sql Destination
I have a lookup component which determines if a record is to be updated or inserted. If it does not find match for a particular row that row is sent to the error output of the lookup component from where it is bulk inserted into the database using sql server destination.

Now the problem is when there are no rows to be inserted, the DTS buffer times out throwing an error. However if i increase the timeout or set it to 0, it hangs on indefinitely.

Is there a way that i can ignore the sql server destination when there are no rows to be inserted.

Thanks

Data Leaked A Buffer With ID 1 Of Type 1
We are using a datareader component to retrieve data from a Pervasive 8.6 database. We have four separate datareader components in various packages retrieving data into our datawarehouse in SQL2005. One of the components has started to fail regularly with the following error.

The other components run without any problems as did this one up until we installed service pack 2. We then started getting these occasional failures. Any thoughts on what is happening here?

Tyring To Figure Out What's In The Buffer Pool
Hi, I'm trying to chase down some bottlenecks, and am currently tyring to figure out what's actually in our data buffer pool.

We've recently upgraded to SQL Server 2005 (sp2a); there's 4GB memory on the box (an active/passive cluster) with the /3GB switch set. I'm working on the learning curve for

sys.dm_os_buffer_descriptors and sys.allocation_units [and boy I sure wish SSMS's query windows wouldn't "copy" in HTML]. Based on BOL and some poking around, I've come up with the following query to list pages used within a given database:

SELECT

count(*) cached_pages_count

,isnull(obj.name, '<unidentified object>') TableName

,obj.index_id

,ind.name

from sys.dm_os_buffer_descriptors bd

left outer join (select

object_name(object_id) name

,object_id

,index_id

,allocation_unit_id

from sys.allocation_units au

inner join sys.partitions p

on au.container_id = p.partition_id -- 2005 compatible, but maybe not in future versions

) obj

on bd.allocation_unit_id = obj.allocation_unit_id

left outer join sys.indexes ind

on ind.object_id = obj.object_id

and ind.index_id = obj.index_id

where bd.database_id = db_id()

group by obj.name, obj.object_id, obj.index_id, ind.name

order by cached_pages_count desc

This would appear to list how many pages are sitting in our buffer pool for which objects for the currently selected database. The thing is, for our "main" database, the vast majority of pages fall in that "unidentified" bucket -- their allocation_unit_ids are not in sys.allocation_units (or tempdb, I checked there just in case).

My question is: what are these pages? Where is this data coming from? Might these somehow be related with our execution/query cache, which appears to be larger than our data cache?

As may be obvious, this is all new to me, and any help would be greatly appreciated!
