I still have transactions in use mainly to set isolation levels. There are obviously no update/delete statements in them. I'm pretty sure this will still add rows to the transaction log even though there won't be any writes to the db data files. Is it still a critical best practice to use RAID 1/0 instead of RAID 5 for the logs? Looking to re-use some existing storage rather than buy new ones. Thoughts?
Hi have have two linked SQL Servers and I am trying to get things workingsmootly/quickly.Should I be using 'BEGIN TRANSACTION' or 'BEGIN DISTRIBUTED TRANSACTION' ?Basicly, these SPs update a local table and a remote table in the sametransaction. I cant have one table updated and not the other. Please dontsay replicate the tables either as at this time, this is is not an option.I have for example a number of stored procedures that are based around thefollowing:where ACSMSM is a remote (linked) SQL Server.procedure [psm].ams_Update_VFE@strResult varchar(8) = 'Failure' output,@strErrorDesc varchar(512) = 'SP Not Executed' output,@strVFEID varchar(16),@strDescription varchar(64),@strVFEVirtualRoot varchar(255),@strVFEPhysicalRoot varchar(255),@strAuditPath varchar(255),@strDefaultBranding varchar(16),@strIPAddress varchar(23)asdeclare @strStep varchar(32)declare @trancount intSet XACT_ABORT ONset @trancount = @@trancountset @strStep = 'Start of Stored Proc'if (@trancount = 0)BEGIN TRANSACTION mytranelsesave tran mytran/* start insert sp code here */set @strStep = 'Write VFE to MSM'updateACSMSM.msmprim.msm.VFECONFIGsetDESCRIPTION = @strDescription,VFEVIRTUALROOT = @strVFEVirtualRoot,VFEPHYSICALROOT = @strVFEPhysicalRoot,AUDITPATH = @strAuditPath,DEFAULTBRANDING = @strDefaultBranding,IPADDRESS = @strIPAddresswhereVFEID = @strVFEID;set @strStep = 'Write VFE to PSM'updateACSPSM.psmprim.psm.VFECONFIGsetDESCRIPTION = @strDescription,VFEVIRTUALROOT = @strVFEVirtualRoot,VFEPHYSICALROOT = @strVFEPhysicalRoot,AUDITPATH = @strAuditPath,DEFAULTBRANDING = @strDefaultBranding,IPADDRESS = @strIPAddresswhereVFEID = @strVFEID/* end insert sp code here */if (@@error <> 0)beginrollback tran mytranset @strResult = 'Failure'set @strErrorDesc = 'Fail @ Step :' + @strStep + ' Error : ' + @@Errorreturn -1969endelsebeginset @strResult = 'Success'set @strErrorDesc = ''end-- commit tran if we started itif (@trancount = 0)commit tranreturn 0
I'm receiving the below error when trying to implement Execute SQL Task.
"The ROLLBACK TRANSACTION request has no corresponding BEGIN TRANSACTION." This error also happens on COMMIT as well and there is a preceding Execute SQL Task with BEGIN TRANSACTION tranname WITH MARK 'tran'
I know I can change the transaction option property from "supported" to "required" however I want to mark the transaction. I was copying the way Import/Export Wizard does it however I'm unable to figure out why it works and why mine doesn't work.
How do I make use of begin transaction and commit transaction in SSIS.
As am not able to commit changes due to certain update commands I want to explicitly write begin and commit statements. but when i make use of begin and commit in OLEDB commnad stage it throws an error as follows:
Hresult:0x80004005
descriptionyntax error or access violation.
its definately not an syntax error as i executed it in sql server. also when i use it in execute sql task out side the dataflow container it doesnt throw any error but still this task doesnt serve my purpose of saving/ commiting update chanages in the database.
I'm taking a database(read-only) backup from one server and restoring it on other server. As soon as restore is done it is bringing database into single-user read-only mode.
why it is bringing the database into single user mode ?
I have two database files, one .mdf and one .ndf. The creator of these files has marked them readonly. I want to "attach" these files to a new database, but cannot do so because they are read-only. I get this message:
Server: Msg 3415, Level 16, State 2, Line 1 Database 'TestSprintLD2' is read-only or has read-only files and must be made writable before it can be upgraded.
What command(s) are needed to make these files read_write?
I'm new to ASP.NET (I normally work with Windows Forms) and have installed the Club Website Starter Kit. I created an Administrators role and a user called "admin". When I run the project locally, everything works as it should - I can log in as admin and I can create new users. I then copied the site to localhost (C:Inetpubwwwroot), but when I run the site from localhost, I can't log in (as admin or any other user); instead I get a message that says, "Your login attempt was not successful. Please try again." Also, I can't create a new user. When I try, I get the following error: Server Error in '/' Application.

Version Information: Microsoft .NET Framework Version:2.0.50727.42; ASP.NET Version:2.0.50727.42 I figure there must be a simple(?) explanation and solution for this problem, and ideally, some sort of step-by-step procedure that new users to ASP.NET can follow to configure a site - such as one of the starter kits - to work correctly. I can honestly say that trying to get this working has been an extremely frustrating experience. If someone could help me out, I would really appreciate it. I've been working on this for two days and feeling I have hit the wall. Thanks in advance.
Hi there,I am getting a real problem with ASP.NET 2.0, all i am trying to do is run a recovert password (using the login controls) and i got the following error.Does anybody know how to fix this? I have tried the SSEUTIL answer here and it didn't work. http://forums.asp.net/909168/ShowPost.aspxI also ensured that Network Services user has READ/WRITE/EXECUTE premissions on the directory below and that each file isn't read only and also that it inherits ACL from the directory which it seems to do..Bit of strange one this, it isn't created (and i am not using) a beta version of VS 2005 Pro... but a full retail version.The PC is the local PC with IIS 5.1 and VS installed... it is the one i am using for developing.. I don't need to copy my files to the IIS directory below as that is where i have created it and open it in VS 2005 from there..I did read that if you use IIS 5.1 then the user should be ASPNET ... but i don't seem to have that use but a Network Services user...Any help or guidance would be really appreciated... i have come to a stop stage and can't get any further..Thanksian Server Error in '/igdotcom' Application.

I am executing a stored procedure something like this
Create Procedure TEST @test1 @test2 AS BeGIN TRANSACTION ONE SELECT... UPDATE.. .... ....
.... TRUNCATE etc and lot of Select,update and delete statements like this ..... COMMIT TRANSACTION ONE
The Block of code which I have b/w BEGIN TRANSACTION AND COMMIT TRANSACTION ..Will it be rolled back if it encounters any errors in the SELECT,UPPDATE,DELETE ..statements which I have with the transaction one. IF not How do I roll back if it encounters any erros b/w the BEGIN TRANSACTION and END TRANSACTION.
I had thought that if any statement failed within a BEING TRANS .. COMMIT TRANS block, then all the statements would be rolled back. But I am seeing different behavior (SQL Server 2000 8.00.2039)
For instance, run these statements to set up a test: --DROP TABLE testTable1 --DROP TABLE testTable2 CREATE TABLE testTable1 (f1 varchar(1)) CREATE TABLE testTable2 (f1 varchar(1)) CREATE UNIQUE INDEX idx_tmptmp ON testTable1 (f1) insert into testTable1(f1) values ('a')
So table testTable1 has a unique index on it..
Now try to run these statements:
--DELETE FROM testTable2 BEGIN TRANSACTION insert into testTable1(f1) values ('a') insert into testTable2(f1) values ('a') COMMIT TRANSACTION
SELECT * FROM testTable2
..the first insert fails on the unique index.. but the second insert succeeds. Shouldn't the second insert roll back? How can I make two operations atomic?
i have a database which get refreshed every day from client's data . and we need to pull heavy data from them every day as reports . so only selects happens on that database.
we do daily population of some table in some other databases from this daily refreshed DB.
will read uncommitted or NOLOCK with select queries to retrieve data faster.
there will be no dirty read as there are NO DML operation in that database so for SELECT which happens concurrently on these tables , will NOLOCK work?
Hi, this is my first week really trying to learn ASP.net (i'm currently working with 2.0).I have a page, that I am trying to set up that will allow the user to input data, now i'm sure that passing data from 1 webpage to 1 table in a SQL database is pretty streightforward, but how do you plan it out when you know that your web page is going to insert multiplte inserts into multiple tables, with the main table PK referencing all?Any ideas? Even just a starting point so I can get going with this? If I can help anymore, please let me know.

I have made sure that the permissions on the DB are set (in Windows) so that all users can modify. The user that is logging in to the DB has status set to DBOWNER.
I have seen others experience the same problem - with ASP.net sites, not Windows Forms sites (thus most of their solutions dont apply to me)
Any ideas on what is wrong and how I can get this to work?
Hi All,Can any one help by giving me the details/difference in using the Transaction Isolation Levels (read uncommitted, read committed, repeatable read, or serializable)in asp.net. I just want to know in which case we can use these things in begining a transaction, and will it improve the performance. thanks in advance Boo
I need to copy two large tables from one database into another, via the internet. I haven't worked out exactly how yet, but the first issue which has occurred to me is that by the time the first table has been exported (via a SELECT clause?) into a suitable file, the second table (to which it is related) will be out of sync. So, how do I ensure that I end up with a snapshot of the two tables, perfectly in sync with each other? I know that BEGIN/END TRANSACTION makes sure that UPDATES to tables remain in sync, but will it work just for SELECT statements?
Greetings,I've been reading with interest the threads here on deadlocking, as I'mfinding my formerly happy app in a production environment suddenlydeadlocking left and right. It started around the time I decided towrap a series of UPDATE commands with BEGIN/END.The gist of it is I have a .NET app that can do some heavy reading (nowriting) from tblWOS. It can take a minute or so to read all the datainto the app, along with data from other tables.I also have a web app out on the floor where people can entertransactions which updates perhaps 5-20 records in tblWOS at a time.The issue comes when someone is loading data with the app, and someoneelse tries an update through the web app: deadlocks-ville on theapplication and/or the web app.Again, I believe it began around the time I wrapped those 5-20 recordupdates to tblWOS on the web app with BEGIN/END. The funny thing isthat the records involved are not the same ones, so I'm thinking somekind of table-level lock is going on.I've played with UPDLOCK in examples, but don't quite understand whatit's attempting to do. Since the web update is discrete and short, andit is NOT updating records that are getting loaded, I'd like theBEGIN/UPDATE/END web transaction to happen and not deadlock the loadingapplication.Any suggestions? I'd be most grateful.thanks, Leaf

I am receiving the following error when I run a stored procedure:Server: Msg 7391, Level 16, State 1, Procedure spXXXXThe SP inserts data into a local (sql 2000) table from a remote sql2000 database. The SP works fine until I add a trigger to thedestination. The contents of the trigger do not appear to matter, as Ihave tried removing everything but one line, which is just a declarestatement. Updating the table with the trigger (even the full trigger)in place does not cause an error. Running the SP without the triggeron the table does not cause the error.I have the exact same setup on another server. Both the SP and thetrigger are IDENTICAL. This setup works on one server, but not theother. The only difference I can see is that the non-working server isWindows 2000 Server, while the working server is Windows 2003 Server.Any idea what's going on here?Thanks in advance.Eric
we have an update sp that must call an insert sp after the update. The update and insert must act like a transaction, ie all or none.
We believe that wrapping most of the update (including call to insert sp) sp in a begin tran block would guarantee the all or none behavior.
However, we're not sure what would happen if one of our developers calls the update sp from within a transaction scope that expects yet something additional to be included in the transaction. Would the begin tran block (assuming no errors in that block) in the sp commit both the update and insert regardless of what happens in the rest of the .net tran scope?
I'm having issues with a query to a view that references a view on a linked server, that in turn references a view on a third server.
Query to view on Server A --> View on Server B --> View on Server C
I can query from A to B using the linked server. I can query from B to C. I can query from A to C.
All servers at the same location on the same domain.
I cannot query a view on A, that references a view on B, where the view on B references a view/table on C
Each linked server configuration uses "Be made using this security context", with the user specified being 'sa'. I was hoping to get security out of the equation for debug purposes, hence the sa use.
I have tried from Query Analyzer using both windows and sql auth.
MSDTC is running on all servers as local system.
The full error returned is:
Server: Msg 7391, Level 16, State 1, Line 1 The operation could not be performed because the OLE DB provider 'SQLOLEDB' was unable to begin a distributed transaction. OLE DB error trace [OLE/DB Provider 'SQLOLEDB' ITransactionJoin::JoinTransaction returned 0x8004d00a]. [OLE/DB provider returned message: New transaction cannot enlist in the specified transaction coordinator. ]
I have been attempting to set up a linked server in SQL Server 2000 to point to an Oracle database (a very old Oracle database, v7!).
The linked server set up works fine. Then I created a database on the same SQL Server. Within that database I created a view which reads information from a view in the Oracle database (linked server). When I attempted to create this view in Enterprise Manager, I get the following error:
"The operation could not be performed because the OLE DB provider 'MSDAORA' was unable to begin a distributed transaction."
And so I created the view in Query Analyzer. This worked perfectly, no errors, and I can now go into Enterprise Manager and call up the view, which happily goes off to the view in the Oracle linked server and pulls back the info. BUT, when I attempt to do the same thing through an application on a different machine (using OLE Db, and a UDL to connect) the same error as above appears.
Does anyone know what this error means, and where I went wrong? Any help greatly appreciated. My view onto the linked server looks like this:
"CREATE VIEW dbo.NLPG_VIEW AS SELECT * from openquery(sadaslink, 'select * from NLPG_VIEW')"
Many thanks in advance for your wisdom!
P.S I wondered whether I need to check if the distributed transaction co-ordinator is running but don't know how. Thanks,
I have 3 development SQL Servers A, B & C, all running SQL 2000 sp3 and Windows 2003. Servers B & C have a linked server pointing to A, and A has one pointing to B & C. The linkedservers all have RPC , RPC out enabled. I have a stored procedure called test on server A.
When the Insert....Exec code above is ran from server B it works fine, however when I run it from Server C, I get error 7391 The operation could not be performed because the OLE DB provider 'SQLOLEDB' was unable to begin a distributed transaction. [OLE/DB provider returned message: New transaction cannot enlist in the specified transaction coordinator. ] OLE DB error trace [OLE/DB Provider 'SQLOLEDB' ITransactionJoin::JoinTransaction returned 0x8004d00a]
But regular linked server calls (directly to tables) and openquery calls work fine from either server...
Eg insert into #tmp Select top 5 first_name, last_name from ServerA.db1.dbo.people
--and this works also
insert into #tmp Select * from openquery(ServerA, 'Exec db1.dbo.test')
Both servers (B & C) appear to be configured the same, and I have reconfigured MSDTC on all three boxes through control panel and component manager, have tried using SET xact_abort, SET implicit_transactions, registry hacks (TurnoffRPCsecurity), basically everything listed on Microsoft, and everything I've been able to find in these groups.

I have 0 items in the right windowpane of the DTC item, is it OK?- registry setting as discussed earlierThe following Registry Keys should be entered:[HKEY_LOCAL_MACHINESOFTWAREMicrosoftMSDTCMTxOCI ]"OracleXaLib"="oraclient8.dll""OracleSqlLib"="orasql8.dll""OracleOciLib"="oci.dll"My entries are:"OracleOciLib"="ociw32.dll""OracleSqlLib"="SQLLib18.dll""OracleXaLib"="xa73.dll"Are they OK?- check if Mtxoci.dll is loadedThere is a Mtxoci.dll in my system32 dir, but how do I tell if it'sloaded? Should I regsvr32 it?- SET XACT_ABORT ON should be use in your SQL statement, for example:SET XACT_ABORT ONBEGIN DISTRIBUTED TRANSELECT statementCOMMIT TRANI've tried that, both in trigger but also surrounding the query thatfires the trigger.Am getting deseperate - please help. Will send candies!TIA
I have a database containing my own tables and data and I wanted tobe able to query this against an accountancy program which has an ODBCdriver. This was never a problem with MS Access and Jet but I hit Jet'slimitations and have moved to SQL.Creating my own SQL database was no problem, but I was unsure of thebest way to be able to be able to have my SQL tables and my accountancysoftware tables appearing in the same Access front end.I created a linked server to the accountancy program. This wassuccessful in that I could see all the tables below the linked server inenterprise manager.My problem occurs when I try to bring the data from these tablesinto my SQL database.I create a new view in my database:-SELECT *FROM OPENQUERY(SAGE_SERVER, 'SELECT * FROM STOCK')(My linked server is called 'SAGE_SERVER' and I am trying to retrieveall columns from the STOCK table.)I then try to save this view and get the following errors.ODBC Error: [Microsoft][ODBC SQL Server Driver][SQL Server]The operationcould not be performed because the OLE DB provider 'MSDASQL' was unableto begin a distributed transaction.[Microsoft][ODBC SQL Server Driver][SQL Server]OLE DB Error Trace[OLE/DBProvider 'MSDASQL' ITransactionJoi JoinTransaction returned 0x8004d00a].Thanks in advance,Marcus Thornton.
