Repost: DTS -- Insert Into Oracle Is SLOW. Any Tips?

Hello all,
I've written a simple dts job that uses oracle (8.x) as a source and oracle (8.x) as a destination. I'm using SQL 2000 and Microsoft's oledb provider for oracle as the two connections. I've chosen "Transform Data Task" with the following SQL "SELECT * FROM REPORTER_STATUS
WHERE LASTOCCURRENCE > TRUNC(SYSDATE)". As you can see, it's very simple, however it's very very very slow. (averages about 1000 rows per minute). In my column transformations, I've selected many to many versus the one to one. There are no activex scripts or anything along those lines. Just a simple push of the data from one oracle box to the other. The table schemas are identical etc... I've had this problem before with writing to Oracle and I can't imagine that it's really supposed to be this slow. If you need more details, please just let me know.
Thank you,
Jeremy
-----------------------------More -------------------------------
The official response from microsoft is that dts only allows for single inserts... not bulk or bcp for oracle. There must be someone out there who has figured out how to configure / modify / call (something) from a dts pacakage to insert millions of records into Oracle in a decent time frame...
thnx again..

I have a stored procedure that queries a database using a Selectstatement with some inner joins and conditions. With over 9 millionrecords it takes 1 min 36 sec to complete. This is too slow for myrequirements.Is there any way I can optimize this query. I have thought aboutusing an indexed view. I haven't done one before, does anyone know ifthis would have potential to improve performance or indeed any otherperformance enhancing techniques I might try.SELECT vehicle.vehicle_idFROM (( [vehicle]INNER JOIN [vehicle_subj_item_assn] onvehicle.vehicle_id=[vehicle_subj_item_assn].vehicle_id)INNER JOIN [subj_item] on[vehicle_subj_item_assn].subj_item_id=[subj_item].subj_item_id)INNER JOIN [template_field] on[subj_item].subj_item_id=[template_field].subj_attr_idWHERE([template_field].template_field_id=@template_field_id) AND([template_field].template_field_type_id=3) AND([vehicle_subj_item_assn].subj_item_value_text=@value) AND(vehicle.end_dtm IS NOT NULL)ThanksGavin

Hi.
Me any my team are soon going to work on a performance critical application. My team has some experience of writing SQL, however we have not done performance oriented coding.
I am looking for a comphrehensive document which lists information for writing good SQL with performance. Please guide if there is such a document or web site.
Thanks,

I need to push 40k rows daily to an Oracle database. I am on a Win2k Pro box with the 8.1 client and ADO 2.6 loaded. I've configured the linked server with the Oracle as well as the Microsoft provider and it takes over a minute to push just 24 rows, less than 100 bytes each, at it. Any suggestions?

Hi All
I decided to change over from Microsoft Access Database file to the New SQLServerCe Compact edition. Although the reading of data from the database is greatly improved, the inserting of the new rows is extremely slow.
I was getting between 60 to 70 rows per sec using OLEDB and an Access Database but now only getting 14 to 27 rows per sec using SQLServerCe.
I have tried the below code changes and nothing seams to increase the speed, any help as I would prefer to use SQLServerCe as the database is much smaller and I€™m use to SQL Commands.
Details:
VB2008 Pro
.NET Frameworks 2.0
SQL Compact Edition V3.5
Encryption = Engine Default
Database Size = 128Mb (But needs to be changes to 999Mbs)
Where Backup_On_Next_Run, OverWriteQuick, CompressAns are Booleans, all other column sizes are nvarchar and size 10 to 30 expect for Full Folder Address size 260

Hi i have a sql server instance on my system and it is linking into an oracle database on another server. When i run queries against this other server...it takes forever...
However, when i use access, and link the table and run the same query against the oracle database...it runs immediatly.
I am very confused as to why there would be such a performance difference and why sql server would run so slow.
I am wondering if it has something to do with the way i configured the linked server. there are several options that I didn't know what they meant.
collation compatible (not selected)
Data access (selected)
RPC (not selected)
RPC Out (not selected)
collation name
connection timeout
query timeout

I posted the following back in May and received the reply below.
I asked again in July, but got no response so I assume that wasn't the way to handle it ...
So -- here is the RePost & Reply.
Question is still open: Is the CD ready yet ?/
Roger
===========================================
Can I get: SQL Express with Advanced Services on a CD (or DVD)
I'm on DialUp so a download would take 24hr+.
I was able to get the MS .NET Framework 2.0 on DVD because an MVP took pity on me and was kind enough to give me the "Secret" URL to the correct Order Desk.
I'm hoping one of you knows the URL for this CD/DVD
Roger
=========================================
Hi Roger,
We're working on CD images for SQL Server Express with Advanced Services in all the languages that SQL Server usually ships in. The English version is in final testing and should be available in a couple of weeks.
Thanks

Hi all,
I have posted a thread on the XML forum but its not getting much traction there so I'm posting a link to it from here hoping that more people will pick it up. Hope that's OK.
I have a problem with a T-SQL query involving XML that is taking FAR too long to run.

Here’s a more in depth breakdown of my problem:
We have 4 regions, currently we only have 3 servers in the field, and therefore only 3 regional id’s are being used to store the actual data of the pbx. The central server (RegionalID = 0) is holding the data for itself and the 4th region until the new server is deployed.
It now has to be deployed and therefore the data migration for this region has to take place.
I am trying to extract all the data for this 4th region (RegionalID= 1) from the central server database from all the relevant tables.
When doing this I will firstly, have to check that the CallerID is valid, if it is, send that entry along with the result set, if it is not valid, Check that the dongle area code is valid, if dongle area is valid select with the result set, and if it is not valid, then check that RegionalDialup = ‘0800003554’ which is the dialup number for this 4th region (RegionalID = 1).
I have a table named lnkPBXUser which contains the following:
if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[lnkPBXUser]') and OBJECTPROPERTY(id, N'IsUserTable') = 1)
drop table [dbo].[lnkPBXUser]
GO
DDL:
CREATE TABLE [dbo].[lnkPBXUser] (
[RegionalID] [int] NOT NULL ,
[pbxID] [decimal](18, 0) NOT NULL ,
[userID] [decimal](18, 0) NOT NULL
) ON [PRIMARY]
GO
Sample data:
INSERT INTO lnkPBXUser(RegionalID, pbxID, userID)
SELECT 0, 543, 2 UNION ALL
SELECT 0, 10961, 6 UNION ALL
SELECT 0, 1012, 17 UNION ALL
SELECT 0, 16499, 26 UNION ALL
SELECT 0, 14061, 36 UNION ALL
SELECT 0, 16499, 2
I have a table named tblDialupLog which has 20 columns, I have selected only the columns I am interested in (below):

You see that the DongleAccessNumber is actually made up of three parts, and it is the middle part (ie.UQ) which i will use to check that the tbldongleArea.DongleAreaCode is valid for that region

Ok, I am dealing with the lnkPBXUser table at the moment,
I need to be able to join lnkPBXUser and tblDialupLog, then compare tblDialupLog.CLI to tblCodes.SubsNDCD + tblCodes.LocCD (when these two columns are concatenated the result will only be a substring of tblDialupLog.CLI. (this is to make sure that the CLI exists in tblCodes.)
If it does exist, then it is part of the fourth region and should be returned in the result set.
If it does not exist, I then need to check that tblDongle.DongleAreaCode is a substring of tblDialupLog.DongleAccessNumber.
If it is a valid DongleAreaCode for that region, then it is part of the fourth region and should be returned in the result set.
If it does not exist, I then need to check that tblDialupLog.RegionalNumber = ‘080003554’.
So from the above tables an expected result would be:
RegionalID pbxID userID
0 1012 17
0 543 2
Please assist, it would be greatly appreciated.

Hi,
I have a table with 110 nvarchar (255) columns in the database. I receive the data from the server (array) and them loop through it to insert the data into the database. The problem is it takes more than 3 minutes to insert (or update) (in memory) the 310 records it got from the array. I am reusing the Statement (with parameters). How could I improve the performance?
It's really a small quantity of data, the CPU in the device is 520Mhz... it should be alright!
Can aynone help me please?
Thanks

Hi,
I have 3 SQL Servers running here. Here are their configurations:
SERVER 1:
OS: Windows 2000 SP 4
SQL: SQL Server 2000 SP 4
SERVER 2:
OS: Windows 2000 SP 4
SQL: SQL Server 2000 SP 4
SERVER 3:
OS: Windows XP Professionnal
SQL: SQL Server 2000 SP 3
Now, as you can see, SERVER 1 and SERVER 2 have identical configurations. Plus, both will accept Windows Authentication and SQL Authentication.
If I try to add a new Registration from SERVER 3 to SERVER 1, it works fine but from SERVER 3 to SERVER 2 it doesn't. I always get an error (SQL Server does not exist or access denied). But, using the exact same user name and password, a connection can be established from SERVER 1 to SERVER 2 and vice-versa. Only when trying to connect froms SERVER 3 to SERVER 2 fails.
Any ideas?
Thanks,

Hello,
I don't know what to do anymore ;o(
I've got 2 servers, with sql server 2000 sp3 and ms windows 2003 server.
I've written a very simple stored procedure to insert 20,000 rows into a very simple table TEST (id int, msg varchar_50)
On the first server (P-IV 2 GHz), it takes 700 ms / 1000 insertions
and on the second (2x Xeon 2,6 GHz), it takes 13 s / 1000 insertions...
(insertion is : INSERT INTO TEST (id, msg) VALUES (@id, 'dummy text'))
...
SQL Server was installed exactly in the same way...
what could I do see where the problem is ? With profiler, I see no difference while logging all events....
please help or give ideas

We had a table that had logical fragmentation of 50%. After rebuilding(with default fillfactor 0) I noticed that inserts are much faster. Ifmy page density is 100% wouldn't I get more page splits? I know I ammissing something fundamental here. Could someone get me back ontrack?Table Size 1.5 millionInsert Size 70KBefore: 15 minutesAfter: 3 minutesIndex:Compound clustered across varchar columnsThere are also a couple non-clustered indexes

I support a website (ASP.NET 2.0) where recently users have been unable to insert data due to timeout issues. The functionality executes a query that inserts a single row into a SQL Server 2005 db table. I tried running this query from the backend, and it took 4:48 to insert a single row! Interestingly, after that initial agony any similar inserts I tried took no time whatsoever. I have checked the execution plan, but unfortunately don't really know what I'm looking for with inserts, as most of my experience with execution plans is with select statements. Any resources anyone could point me to for troubleshooting this would be much appreciated.
Thanks,
-Dave

Hi everybody !!! I have a problem with database SQL server 2000, and I need anyone help me.
I have PC machine with hardware configuration following:
+ RAM : 512M
+ CPU : 2.4 GHz (intel Pentium 4)
+ System : Microsoft Windows Server 2003 Enterprice Edition , Service Pack 1
(this is call Machine1 )
and other Server machine with hardware configuration the following :
+ RAM : 2G
+ CPU : 3.6 GHz( intel Xeon)
+System : Microsoft Windows Server 2003 Enterprice Edition , Service Pack 2
(use RAID 5)
(this is call Machine2 )
.And SQL Server 2000 is installed in these machine.
I created one table and one script to insert several records into this table. and script for inserting:
declare @count int , @max int
set @count =1
set @max = 5000
WHILE (@count < @max or @count = @max)
BEGIN
insert into TBAT_STOCKEOD(TRDT,SEQNO,COMPID,TRANSTYPE) values('20071219',cast(@count as varchar(5)),'13215','1')
set @count = @count +1
END
I execute this script on Machine1 and Machine2 :
+ Machine1 : spent 3 seconds.
+ Machine2 : spent 30 seconds. I don't understand why Machine2 is slower than Machine1 ( while configuration of Machine2 is better than Machine1's ). I don't know what happen.
I checked resource usages in perfmon when SQL server execute script and result following :
Machine1:
Proccessor used 100%
whereas,Machine2 used physical Disk 100%
Is there the way to configurate SQL server to improve speed writting of hard disk?

I posted this under 'microsoft.public.sqlserver.client' but got no reply.Any help with this problem would be greatly appreciated---------------------I developed a database under SQL Server 2000, with Access 2000 on Windows2000 as client. This had been running fine for several years. The client isnow upgrading to Windows XP, and has come across a display problem on thereports. The figures are correct but are now displayed with lots of trailingzeros e.g365.00000I have built a test system but cannot duplicate the problem :-( . Also theproblem varies between computers, and even between different users on thesame computer. One solution that seems to work is to explicitly cast alloutput from the server e.g.CAST ( TonsLoaded AS INT) TonsLoadedbut this is a pita since there are 141 stored procedures.Has anyone seen this problem? I haven't found anything in the newsgroups orany Knowlege Base article. It looks like it is to do with Windows XP as theclient ...David

I am looking for a way to truncate raw files without losing the metadata. The metadata of the raw file should be automatically detected at run-time. The result will be a raw file with the same metadata as the original file, but no data in it.
There are two reasons I would like such a tool. First, I want to erase the potentially sensitive data stored in the raw files. Second, I want to keep Validation enabled so that development is simpler.
Is anyone aware of such a tool?
Thanks,

I am using an aggregate with the OVER clause.Running the script is fast less than 1 second but when I say insert into a temp table the execution plan is very different at it take 8 seconds.I have attached the execution plans. Also the Statistics IO, Time messages. I am using SQL Server 2014 with backward compatibility to 2008 R2.
if (select OBJECT_ID('tempdb..#MM')) is not null drop table #MM

Here’s a more in depth breakdown of my problem:
We have 4 regions, currently we only have 3 servers in the field, and therefore only 3 regional id’s are being used to store the actual data of the pbx. The central server (RegionalID = 0) is holding the data for itself and the 4th region until the new server is deployed.
It now has to be deployed and therefore the data migration for this region has to take place.
I am trying to extract all the data for this 4th region (RegionalID= 1) from the central server database from all the relevant tables.
When doing this I will firstly, have to check that the CallerID is valid, if it is not valid, then check that RegionalDialup = ‘0800003554’ which is the dialup number for this 4th region (RegionalID = 1).
I have a table named lnkPBXUser which contains the following:
RegionalID pbxID userID
0 1012 17
0 543 2
0 10961 6
0 16499 26
0 14061 36
0 15882 2
4 15101 6
4 15101 26
6 16499 2
6 16012 26
I have a table named tblDialupLog which has 20 columns, I have selected only the columns I am interested in (below):

Ok, I am dealing with the lnkPBXUser table at the moment,
I need to be able to join lnkPBXUser and tblDialupLog, then compare tblDialupLog.CLI to tblCodes.SubsNDCD + tblCodes.LocCD (when these two columns are concatenated the result will only be a substring of tblDialupLog.CLI. (this is to make sure that the CLI exists in tblCodes.)
If it does exist, then it is part of the fourth region and should be returned in the result set.
If it does not exist, I then need to check that tblDongle.DongleAreaCode is a substring of tblDialupLog.DongleAccessNumber.
If it is a valid DongleAreaCode for that region, then it is part of the fourth region and should be returned in the result set.
If it does not exist, I then need to check that tblDialupLog.RegionalNumber = ‘080003554’.
So from the above tables an expected result would be:
RegionalID pbxID userID
0 1012 17
0 543 2
Please assist, it would be greatly appreciated.
Regards
SQLJunior

Hello,
In a Data Flow Task, I have an insert that occurs into a SQL Server 2000 table from a fixed width flat file. The SQL Server table that the data goes into is accessed through an OLE DB connection manager that uses the Native OLE DBMicrosoft OLE DB Provider for SQL Server.
In the OLE DB Destination, I changed the access mode from Table or View - fast load to Table or View because I needed to implement OLE DB Destination Error Output. The Error output goes to a SQL Server 2000 table that uses the same connection manager.
The OLE DB Destination Editor Error Output 'Error' option is configured to 'Redirect' the row. 'Set this value to selected cells' is set to 'Fail component'.
Was changing the access mode the simple reason why the insert from the flat file takes so much longer, or could there be other problems?
Thank you for your help!

I am developing a SSIS package for inserting data in an Oracle database table. but looks like the 'bulk insert task' in SSIS does not support oracle database. I cannot set the destination connection property to use the oracle database connection.
I have created one OLEDB connection pointing to my oracle database. (using 'Oracle Provider for OLEDB' and I tried 'Microsoft OLEDB provider for Oracle' also). this connection is working fine.
When I go to the connection property in the 'Bulk Insert Task's edit dialogue box, in the DropDown list, I don€™t see my Oracle connection listed there. (but a SQL server database connection existing in the same package could be seen).
Does anyone have solution for this problem?
