I've an issue while calling Oracle Stored procedure from MS SQL Server 2012 using LINKED SERVER, It gets connected and do the execution, But sometimes, it was disconnected and says this message 'A severe error occurred on the current command. The result if any should be discarded'.

I have maintance plan to rebuld indexes and reorg data on all db
it fails with Error
[Microsoft SQL-DMO (ODBC SQLState: 01000)] Error 0: This server has been disconnected. You must reconnect to perform this operation.
What could be the problem?
Thank you

I setup an availability Group. (Only 2 servers - Primary And secondary) -- 21 , 22
I also define an listener . IP .. 23
1- In First step I connected To Listener (23) And in a while I inserted A record to a table .
While 1=1
insert into Tbl_T1(f1,f2) Values (1,2)
2- in second, I Stop the primary .
- I expected this while whitout disconnect, continue.
3- The while code stopped whit this message :
Msg 64, Level 20, State 0, Line 0 A transport-level error has occurred when receiving results from the server. (provider: TCP Provider, error: 0 - The specified network name is no longer available.)
4- I execute again the script, And it worked in new primary.
My questions :
1- is the listener disconnected between switched primary and secondary ? OR have we data loss between switching?
2- I did some huge update on Primary that fill the Log fiel space. And in last Update I got this error :
Msg 9002, Level 17, State 2, Line 27
The transaction log for database 'Your_DB' is full due to 'LOG_BACKUP'.
Is this (Fill All space) a reason to switch primary? Or not ?
Hi ,
On my Desktop i registered Production Server in Enterprise Manager
on that Server if i go to SecurityLinked Servers
There is another Server is already mapped, when i am trying to see the Tables under that one of the
Linked Server i am getting the Error message saying that
"Error 17 SQL Server does not exist or access denied"
if i went to Production Server location and if i try to see the tables i am able to see properly, no problems
why i am not able to see from my Desk top
i am using the sa user while mapping the Production Server on my DESKTOP using (ENTERPRISE MANAGER)
And i check the Client Network Utility in the Alias using Named Pipe only, i changed to TCP/IP still same problem
What might the Problem how can i see the Tables in Linked Server from my DESKTOP
Thanks
I am using Linked Server in SQL Server 2008R2 connecting to a couple of Linked Servers.
I was able to connect Linked Servers, but I cannot point to a specific database in a Linked Server, also, I cannot rename Linked Server's name.
How to point the linked server to a specific database? How to rename the Linked Server?
The following is the code that I am using right now:
USE [master]
GO
EXEC master.dbo.sp_addlinkedserver
@server = N'Machine123Instance456',
@srvproduct=N'SQL Server' ;
GO
EXEC sp_addlinkedsrvlogin 'Machine123Instance456', 'false', NULL, 'username', 'password'
Is there a way to bypass the syntax checking when adding a stored procedure via a script?
I have a script that has a LINKed server reference (see below) .
INSERT
INTO ACTDMSLINKED.ACTDMS.DBO.COILS ..etc.
ACTDMSLINKED does not exist at the time I need to add the stored procedure that references it.
PLEASE to not tell me to add the LINK and then run the script. This is not an option in this scenerio.
Thanks,

Hi ...
This is a C++ / ADO / SQL question. Maybe not the right forum but I am guessing there are some programmers out there ...
I am trying to use ADO disconnected recordset to insert data into a sql table. I am using AddNew(vField, vValue) with UpdateBatch(). The code below does not throw any exceptions ... but does not add data to the table.
Any comments are appreciated,
Thanks,

We're constructing a three-tier application. We want the middle tier to
extract a recordset from the database, disconnect from the database,
then pass the recordset to the front tier. After changes have been made
by the front tier, it will pass the recordset back to the middle tier,
which will reconnect, and update the database.
The problem:
Using stored procedures, the recordset is no longer available
once the connection has been closed. Is there any way, using stored
procedures, to be able to keep the recordset available after the
connection has been closed, either by preserving it, copying it, or
otherwise?

Hello,
I'm having a problem with two mirrored databases, using SQL Server 2005 SP2, that autmatically failed over last night for unknown reasons. I was trying to fail them back over to the primary SQL server because it says the mirror is disconnected and out of sync. Other databases failed over too, but I was able to fail those back over without a problem. It's just these two. I removed the mirror from the secondary server thinking that this would allow me to restore the database back on the primary server, but that didn't help.
These two databases show a status of (Principal, Disconnected / In Recovery) and I still cannot do anything with the two databases on the primary server. When I try to pull up the properties for them, I get the following error:
"Database <Name> is enabled for Database Mirroring, but neither the partner nor the witness server instances are available: the database cannot be opened.(Microsoft SQL Server, Error: 955)"
I cannot delete, detach, Alter or do anything with the databases. If I could just delete them that would be fine so I can just do a restore, but I can't seem to do anything.
Does anyone know what I can do to resolve this problem.
Thanks in advance!

I have a mobile application written in vb.net using MsSQL and I want to use disconnected datasets to sync up to a remote MySQL database. is this possible? Its a two way sync, i.e I download and upload info.
Any suggestions, articles, etc would be great.
Its been almost 10 years since I have had to do work with good-old RecordSet objects...
I am filling a RecordSet with data returned from a SQL server via a stored procedure. I then set the ActiveConnection property to Nothing in order to disconnect it so I can make changes to it.
But when I try to set the value on a given row I get back a "Multiple-step operation generated errors. Check each status value" error message. My understanding is that this is indicative of trying to use the wrong datatype. I have verified that the type is correct (I am dealing with integers) so I am at a loss for what the problem could be.
Here is my code:
Set rsPackages = CreateObject("ADODB.RecordSet")
rsPackages.CursorLocation = adUseClient
rsPackages.LockType = adLockBatchOptimistic
rsPackages.Open "EXECUTE stp_FetchPackageData", myConn
rsPackages.ActiveConnection = Nothing
Response.Write("Value: " & rsPackages("TotalCount")) ' returns 0
Response.Write("Data Type : " & rsPackages.Fields("TotalCount").Type) ' returns 3 = adInteger
rsPackages("TotalCount") = 1 ' throws multi-step error
Oddly enough, when I look at the Attribute property of the field I get back a value of 112. When you break it down I think that value indicates the row value is read-only? (Could that be my problem? Just a really bad/unhelpful error message?) But if I try to change it I get back a message saying cannot be done since RecordSet is already open.
Thanks,
Jason
I have a .Net database application that we've successfully deployed in a connected environment. Now we have a client that has the need to store data on a central SQL Server and publish that data out to tablet PC's that will be able to disconnect from the central SQL Server. At some point those tablet PC's will come back in and connect to the central server via VPN and will need to push their changes back to the server. Some fundamental questions:
1) Am I correct in assuming that replication is the best way to accomplish this?
If so,
2) Which replication type sounds appropriate to the above scenario?
3) Am I correct in assuming that the tablet PC's will need some version of SQL Server to support editing of the data in the disconnected state?
My perhaps incorrect first take on this was that we could use a licensed SQL Server on the central server and SQL Server Express as a replication subscriber on the tablet PC's.
Any guidance greatly appreciated!
Hi
While a database upgrade schema changes were being made the Mirror became disconnected will this recover itself when it reconnects or will it be the case that we will have to copy the db files to the Mirror and set it up from scratch.
It was set up as a synchronise mirror
After adding the Witness Server to the Mirror session, the Witness Connection state between the Mirror and Witness Connection is Disconnected and the state between Principal and Witness Connection is Connected.
The procedures defined in Books Online was used to setup Database Mirroring...when the Witness server was added to the Mirror session, only the alter database T-SQL statement was executed on the Principal server.
ALTER DATABASE <db_name> SET WITNESS = 'TCP://<servername>:<port>'
After executing the above statement, a few seconds later the state between Principal and Witness Connection changed to Connected and the state between Mirror and Witness Connection remains Disconnected.
The Mirror session is not using Certificates, every server is on the same domain, using the same domain login account, and all servers have SP2 installed running Enterprise Edition.
Any idea's why the state between Mirror and Witness Connection remains Disconnected?
Thanks,
I have a system use MS SQL 2005 & .NET 2.0, my tables don't have rowversion, but I heard SQL 2005 manage a rowversion by itself, can I use this to do a "ConflictDetection".All I try to do is I want to get a error when I try to update a row which been modified by someone else after I read row. Thanks.
View 1 Replies View RelatedHi All,
I'd like to throw this idea 'out there' to see if I'm missing something I'll later regret.
I'm looking to resolve a scalability issue within our point-of-sale program. Currently the PK on transactional tables (sales and orders) is created by the application layer using a 'MAX(PKCol) + 1' mechanism. Obviously this requires that all users of the system, whether they're local or remote, have current data at any time they wish to insert. It's this limitation I'd like to remove. Most sites are using MS SQL Server 2000. No sites use anything specific to a later version.
By having a PK that can be generated independently of a 'master' database we can overcome this issue. The PK values will need to be unique within a 'group' of shops and able to be generated by a program operating at any level. From 'head office' which manages a number of shops, to the server at a given shop and even the register / till itself should be able to create ID's while disconnected from the server (using a local database).
It seems there's three main ways to accomplish this:
- Identities,
- MachineID, CurrentPK composite.
- GUID's
Identities: I've ruled out identities as I believe the administration overhead of dealing with them makes them impractical (there may be several hundred registers and therefore as many ranges to be set up within a group).
MachineID, CurrentPK composite: The MachineID references a Machine table which has an entry for each ethernet MAC address which connects to the database. The reason I chose to store the MAC in another table rather than simply using it as column is that I'm fetching it from sysprocesses.net_address(nchar(12)) and believe it's computationally cheaper to use an int than a text column. This mechanism means that we can still expose the PK to the user in some cases (eg: InvoiceNumber printed on a receipt). When the local database is not up to date (usually due to network problems) there will be cases where the CurrentPK will be duplicated but kept unique since it's coupled with the new MachineID. The big drawback to this method is that all current code will need to be revised to deal with the composite keys (this will be a significant amount of development).
GUIDs: Ugly to look at and time-consuming to type. They're not something which you'd expose to a user unmodified so realistically this means altering existing code to use a new 'user friendly' number where the PK is currently exposed to them. The use of GUIDs rule-out the use of clustered indecies on tables they're the PK for lest most inserts cause a page split. The splits would also necessitate more frequent index defrags / rebuilds. Using a non-clustered index incurs a penalty Vs a non-fragmented clustered one (doesn't it?) so while this avoids page-splits it comes at a cost.
After all that I think the best solution is to use GUIDs with a non-clustered index for each of the PK's. While it might not be the fastest of the options (slower reads/joins Vs composite PK) it will be significantly faster to develop while maintaining acceptable performance.
Thoughts?
Hello, Code below returns the following error:
Multiple-step OLE DB operation generated errors. Check each OLE DB status value, if available. No work was done

rsSearch.Open sSql, cnTraining
set rsSearch.ActiveConnection = nothing

My goal is to get a disconnected recordset. The problem here occurs when i try to use the adUseClient value (3) for the CursorLocation. If I don't use a 3 in the CursorLocation it works fine. Hoewever i'm almost certain i have to use the 3 in order to disconnect the recordset. Any ideas? Is my connection string not set up properly to get a disconnected recordset?
We have mirroring set up on SQL 2005(SP2) on windows server 2003 servers for 6 production servers to DR servers. It is high performance mode(asynchonous). We are using fully qualified server names with default 5022 port. Prod and DR are using same domain service account.
We had network outage for about 30 minutes last weekend and after that network was restored back to normal. Also few SQL 2000 servers have logshipping and it automatically started syncing up after network was restored. However mirroring didn't start automatically. Partners were in disconnected state and endpoints were stopped. For one database, log grew to 40 GB using most of the disk space.
Then we maually had to run
ALTER ENDPOINT Mirroring STATE = STARTED
and then it started syncing up.
Now the question is why it doesn't start syncing up automatically after network is back to normal and recognize the partner?
Is there anyway we can setup timeout or any parameter like that to specify how many times or how long partners try to connect with no luck and then give up?
Mintu
We're using ADO disconnected recordsets. On SQL 2000, we could update these on the client (without propagating the changes to the server) even if the underlying view or table was non-updatable.
When running our apps against SQL 2005 (using the same client-side environment), we can no longer change any attributes of those disconnected recordsets, that connect to a non-updatable database object (the rest of the app runs fine, we can update all updatable database objects through disconnected recordsets) . Does SQL 2005 respond to such calls differently from SQL 2000, so that ADO recordsets are built in a new way (which makes them read-only in our setting)?
Thanks for any suggestions.

Hello all,
View 12 Replies View RelatedI have an update query in an OLE DB Destination (access mode: SQL Command) that updates a table with an INNER JOIN from another table in another database. I'm getting the error, "No disconnected recordset available for the specified SQL statement". Does this have to do with the SQL query trying to access the other database? How can I get around this error?
View 4 Replies View RelatedWhat is the most efficient standalone .NET class that can hold a single disconnected record? The class must also retain column names, but other schema is not relevant (.NET data type is sufficient).If I understand System.Data.Common.DbDataRecord, it provides an interface on a DbDataReader, and has no storage of its own.I'm familiar with DataSet, is that the only .NET-standard class to do this?

View 7 Replies View RelatedI am having trouble setting up my Pull Subscription and I am new to replication.
I have several servers hosting a databased website that will be the same, except for user input and traffic. Quite simply, I need to copy most tables, SPs and data from network to network. I can't use FTP/Web synch ... as I mentioned the networks do not touch eachother or the internet.
On server Web1, it was easy to create a Publication called Pub via the wizard for my database: TheDB. Then on Web1, again, I added a Subscription to the Publication, indicating my second server, Web2, and the same database name: TheDB (I have already backed up and restored TheDB to all my servers). Here's one of the sp's I ran on Web1:
use [TheDB]
exec sp_addsubscription @publication = N'Pub', @subscriber = N'Web2'', @destination_db = N'TheDB', @sync_type = N'Automatic', @subscription_type = N'pull', @update_mode = N'read only'
GO
This is where I feel stuck. Using the wizard on Web2 doesn't allow me to see Web1. So I tried the following on Web2:
use [TheDB]
exec sp_addpullsubscription @publisher = N'Web1', @publication = N'Pub', @publisher_db = N'TheDB', @independent_agent = N'True', @subscription_type = N'pull', @description = N'', @update_mode = N'read only', @immediate_sync = 1

GO
I copied the snapshot folder, ie. 20070709134423, onto CD and moved it into Web2's default replication folder, but I always receive: cannot connect to Distibutor. I've tried using an Alias, as well, but don't understand exactly how I should point that either. I checked the publication's PAL and my Web2 user has rights and is an owner of the Web2 TheDB database.
Any help is appreciated.

Hi
I have created a linked server from SQL Server 2005 (SP 1) to SQL Service 2000 (SP 4) with a sql server login that is available on both servers but with different passwords and permissions.
I am getting the following error while accessing the linked server in management studio based on the scenario given below ;
------ Error Message Starts
OLE DB provider "SQLNCLI" for linked server "(SQL Server 2000 instance name)" returned message "Communication link failure".
Msg 10054, Level 16, State 1, Line 0
TCP Provider: An existing connection was forcibly closed by the remote host.
Msg 18456, Level 14, State 1, Line 0
Login failed for user 'abc'.
------ Error Message Ends
Consider login name is abc.
Now this login abc has sysadmin rights on sql server 2005.
The same login abc has only db_datareader rights on sql server 2000 on just one database and is not associated with any fixed server role.
I have configured the linked server using the following options;
1. I have tried impersonating login from SQL Server 2005 to SQL Server 2000 .
2. I have also tried specifying remote login / password option.
Anyone having any idea, would be of great help.

how i can execute this trigger
Can I connect from a SQL Server 2005 database to a SQL Server 2000 database, without establishing a linked server connection.
I need to fire a SELECT query on a SQL Server 2000 database, but don't want to add it as a linked server. Is there any way I can do this or its not possible??
I have a Sybase Adaptive Server Enterprise server which I need to set up as a linked server in SQL Server 2005. The Sybase server is version 12.5.2, and the Sybase ODBC driver version is 4.20.00.67. I have already installed the Sybase client software on the server.
I also created a SystemDSN on the SQL Server to connect to the Sybase server. I tested the connection and it was able to connect.
I ran the following code to create the linked server:
<code>
EXEC master.dbo.sp_addlinkedserver @server = N'LinkedServerName', @srvproduct=N'Sybase', @provider=N'MSDASQL', @datasrc=N'Sybase System DSN', @provstr=N'"Provider=Sybase.ASEOLEDBProvider;Server Name=servername,5000;Initial Catalog=databasename;User Id=username;Password=password"'

I then ran sp_tables_ex to make sure I could view the tables in the Sybase database. Here is the error message I get:
<code>
OLE DB provider "MSDASQL" for linked server "LinkedServerName" returned message "[DataDirect][ODBC Sybase Wire Protocol driver]Error parsing connect string at offset 13. ".
Msg 7303, Level 16, State 1, Procedure sp_tables_ex, Line 41
Cannot initialize the data source object of OLE DB provider "MSDASQL" for linked server "LinkedServerName".
</code>
Any ideas what is happening here?

View 2 Replies View RelatedI was trying to figure out what the OPENQUERY Syntax is to Insert into SQL Server Table from Oracle Linked Server.
View 7 Replies View RelatedWe have oracle linked server created on one of the sql server 2008 standard , we are fetching data from oracle and updating some records in sql server . Previously its working fine but we are suddenly facing below issue.
Below error occurred during process .
OLE DB provider "OraOLEDB.Oracle" for linked server "<linkedservername>" returned message "".

Cannot get the data of the row from the OLE DB provider "OraOLEDB.Oracle" for linked server "<linked server name>".
I'm trying to link SQL Server 2000 sp3 to SQL 2005 64 bit. I keep getting Error 17 sql server does not exist or access denined. I tried adding remote user mapping and chaning the linked server properties to "Be made using this security context" without any success.
Any help is appreciated.
I receive the following error message when I run a distributed query against a loopback linked server in SQL Server 2005:
The Microsoft Distributed Transaction Coordinator (MS DTC) has cancelled the distributed transaction.
To resolve this problem, I was told that running a distributed query against a loopback linked server is not supported in SQL Server 2005. And I am suggested to use a remote server definition (sp_addserver) instead of a linked server definition to resolve this problem. (Although this is only a temporary resolution, which will deprecate in Katmai)
However, I run into another problem when I use the remote server definition. I receive the following error message:
Msg 18483, Level 14, State 1, Line 1
Could not connect to server 'ServerNameSQL2005' because '' is not defined as a remote login at the server. Verify that you have specified the correct login name.
Could anyone please help me out?
(I include the reproduce steps for the first error message, followed by my resolution that generates the second error message)
======
Reproduce steps for the first error message
======
On the ComputerAInstanceA instance, run the following statement to create a database and a table:
CREATE DATABASE DatabaseA
GO
USE DatabaseA
GO
CREATE TABLE TestTable(Col1 int, Col2 varchar(50))
GO
INSERT INTO TestTable VALUES (1, 'Hello World')
GO
On the ComputerBInstanceB instance, run the following statement to create a database and a table:
CREATE DATABASE DatabaseB
GO
USE DatabaseB
GO
CREATE TABLE TestTable (Col1 int, Col2 varchar(50))
GO
On the ComputerAInstanceA instance, create a linked server that links to the ComputerBInstanceB instance. Assume the name of the linked server is LNK_ServerB.
On the ComputerBInstanceB instance, create a linked server that links to the ComputerAInstanceA instance. Assume the name of the linked server is LNK_ServerA.

BEGIN
SELECT * from LNK_ServerA.DatabaseA.dbo.TestTable
END
GO
