SQL Server Linked Server Issues with MVC 5

I have 2 linked servers
Server A = MYOB ( custom 32 it ODBC Driver )
Server B = SQL Server 64 Bit.
They link fine using windows authentication - and I can run the following no problem in SQL Management tools ( as part of a stored proc ) .
DECLARE @MaxID varchar(100)DECLARE @Query varchar(MAX)
-- Insert Sales
SELECT @MaxID = MAX(SaleID) FROM [r2hserver\SQLexpress].artoo.dbo.MYOB_Sales
SELECT @Query = 'INSERT [r2hserver\SQLexpress].artoo.dbo.MYOB_Sales SELECT * FROM OpenQuery(MYOB,''SELECT * FROM Sales WHERE SaleID > ' + @MaxID + ''')'
EXEC(@Query)
The problem is: Whenever execute the stored procedure from within a MVC 5 Web App ( EF6 ) - I get :
Unable to start a nested transaction for OLE DB provider "SQLNCLI11" for linked server "myserver/SQLexpress".
A nested transaction was required because the XACT_ABORT option was set to OFF.
and if I set XACT_ABORT ON - I get : Microsoft Distributed Transaction Coordinator (MS DTC) has stopped this transaction.
I cannot figure out how to make it run! I have turned firewalls off and tried many different config.
Ideas?

SQL 2005 Linked server to Oracle append

Hi Oracle Exprets,
i am using an SQl 2005 linked server too pull data from specific table in Oracle data base.
the thing is i have to pull data daily and append this data to the exsisting table.
here is my code :
EXEC sp_tables_ex @table_server ='LINKED_ORA',@table_schema='Myschema'
INSERT INTO dbo.ARS20091
SELECT * FROM OPENQUERY(LINKED_ORA,
'SELECT
TROUBLEID,
CREATE_DATE,
DATE ''1970-01-01'' + CREATE_DATE / 24 / 60 / 60
CREATEDATE
FROM CLIENT_TROUBLE
WHERE CREATE_DATE between ''1230768001'' AND ''1239043005''');
GO
this code works but i have to change the date daily and do a complete insert in a new table.
Is there a way to append data daily ?
thanks

Hi sanjay,
but why sysdate is giving me the today's date and when i use getdate ...it does not give me anything..
i am using openquery tooracle data base..usually i have to use Oracle command..

Ms sql server linked server with OraOLEDB.Oracle provider session handling

Hi everyone!!
Here's my situation:
I have a MS SQL Server 2008 R2 with a linked server to Oracle via OraOLEDB.Oracle provider.
I use a .net application to open a connection to my sql-server, execute a select that collects data through the linked-server-connection from the oracle database and after that I close to connection to the sql.
It does work so far,
but when I start my application, exit it proberly and start it again it seems that i get the same session as before (which is for some reasons very bad).
Is that the right/normal behavior?
Is there any way to avoid that?!
How does the OraOLEDB.Oracle provider handle the sessions if used in/as a linked server?
thanks and greetings,
exoc

Ｈii Rouann,
Does the error occur when you call the stored procedure from SSIS package and map SSIS variables to the parameters in the stored procedure? Can you run the store procedure from SSMS properly? If you can run the stored procedure from SSMS, the issue seems
to occur due to the date format mismatch between the SSIS variables and the parameters in the stored procedure.
If you cannot run the stored procedure from SSMS as well, the issue should occur due to the incorrect data conversion within the store procedure itself as Tom mentioned.

SQL 2000 LINKED SERVER ERROR 7303 WITH SQL 2012 ON WINDOWS SERVER 2012 R2

Hi all,
I have a problem with SQL Server 2012 and a linked server for SQL 2000 database.
System specification:
Windows server 2012 64 bit
SQL SERVER 2012 64 bit
REMOTE SERVER SQL 2000 32 bit
I've installed sql native client 32bit,create a SYSTEM DSN odbc connection with "SQL Server" driver named "MYSERVER".
Create a linked server with the query below in SQL 2012:
EXEC master.dbo.sp_addlinkedserver @server =N'MYSERVER', @srvproduct=N'MYSERVER', @provider=N'MSDASQL', @datasrc =N'MYSERVER', @location=N'System';
EXEC master.dbo.sp_addlinkedsrvlogin @rmtsrvname=N'MySERVER',@useself=N'True',@locallogin=NULL,@rmtuser=NULL,@rmtpassword=NULL
GO
but when i browse the linked server i receved error 7303.

You need 64-bit MSDASQL. It is the bitness of the server you are connecting from that matters. 64-bit executables cannot hook into 32-bit DLL.
However, I suspect that you will not get things to work anyway. At least I have not seen anyone this far who has been able to set up a linked server from SQL 2012 to SQL 2000. I know that when I tried this, the following providers had this result:
SQLNCLI11 - does not support connections to SQL 2000.
SQLNCLI10 - failed with some obscure message that I don't recall.
SQLNCLI - Don't recall that the problem was here.
SQLOLEDB - SQLOLEDB is always replaced with the most recent version of SQLNCLI, so this fails because of lack of support.
I don't think I got through all version of the ODBC drivers, though.

SQL Server Link Server issue.

Hi,
I have setup a linked sql in SQL Server 2000 to connect to an Oracle 9i database. When I try to select from a table through the link server I get the following error message.
Could not execute query against OLE DB provider 'OraOLEDB.Oracle'.
OLE DB error trace [OLE/DB Provider 'OraOLEDB.Oracle' ICommandText::Execute returned 0x80040155].
This is for a table without any nvarchar2 columns (I get a different error for tables containing those datatypes).
Any ideas?
Thanks
Sanjay

Ralph,
1. Right-click on the linked server you created, select Properties from the popup menu.
2. In Linked Server Properties dialog box, click Options... button under Provider Name dropdown combo.
3. Check (or enable) "Allow InProcess" option.
4. Click Apply button.
5. Click Ok button.

SQL Server linked server to Oracle

We have a SQL Server instance with a linked server to Oracle 9i. When doing a select * (from Oracle) into some_table everything works as expected.
There is a project to move the SQL Instance to a new clustered server. We confirmed that the OS, SQL and Oracle Driver versions are the same. The problem is that when we run the exact same statement the table is being created with unicode columns.
For Example:
Oracle
Col1 Varchar2(20),
Col2 Varchar2(100)
Select into on current SQL Instance creates
Col1 Varchar(20),
Col2 Varchar(100)
Select into on new SQL Instance creates
Col1 NVarchar(20),
Col2 NVarchar(100)
Any help to identify how to resolve this issue?
Thank You,
Michael

Hi Michael,
The varchar2 data type in Oracle database and nvarchar data type in SQL Server is mapped to DT_WSTR data type in SSIS, while the varchar data type in SQL Server is mapped to DT_STR in SSIS. In your case, when loading the Oracle data to nvarchar columns SQL
Server table, you can extract Oracle data using a source adapter and directly load the data to the SQL Server table. When loading the Oracle data to varchar columns SQL Server table, you need to convert the DT_WSTR data type columns to DT_STR data type columns
before inserting into SQL Server table. To do the data conversion, you can use a Data Conversion Transform.
If you want to do it by using T-SQL rather than SSIS, please ask a new question in the T-SQL forum where you can get dedicated support.

Setting up OracleXE as SQL Server Linked server

I have recently installed OracleXE locally following the standard installation instructions. On the same machine I also have a local instance of SQL Server. I want to set OracleXE as a linked server to the Instance of SQL Server.
Can any provide me with some idiot guide instructions to follow.

Assuming you have all the privileges to create and publish in Designer and webi?deski
1) Create system DSN on the server and your machine (in case if you are developing on your system and exporting to server)
2) In Designer, Create a Connection
3) Design Universe
4) Export universe
5) Create a report (DeskI/ WebI) depending on your need.

DNS Server Having Intermittent Issues with Open Directory

I work for a school and we're undertaking the large task of moving from Xserves running 10.6.8 to Mac Minis running 10.9. I have a lot of experience with OS X Server (I held ACSA up until they ditched it, and ACTC through the current OS) but I've hit a fairly large snag in configuring our DNS server. We currently run DNS via an AD server that is being retired at the end of the summer, so this is the first time our DNS will be Mac-based. That said, our network is ridiculously simple as we are a very small school. For the most part it's a flat network using the same IP range for our wired and wireless internal clients (we do have a vlan for guests but that's through Aerohive). I configured the DNS by hand, recreating the entries in our AD server (there were only about a dozen) and then adding in things that should have been there in the first place (e.g. printers and some other devices with static IPs that I'd like FQDNs for). Everything seemed to be working fine...until trying to log into Open Directory accounts.
For some background, the DNS server running 10.9 was the first server we upgraded and it was a completely clean install. We run DHCP on another Mac Server currently running 10.6.8 and it does have the proper OD server listed. All DNS entries for the OD server match our current DNS server. The issue is that it's taking some users 5-6 tries to log in with their network accounts. The errors they receive range from the login window shaking to it stating the user cannot log in at this time. This seems to be worse on client machines running 10.9. but it's appearing on machines running 10.6.8-10.9.3.
In my troubleshooting, I found that if I log in as a local user to one of those machines and do a dig for the OD server the results vary, this is where it gets weird. For example, if I dig ourodserver.ourdomain.org it will sometimes return host not found or it will sometimes resolve. If I ping the same thing it will sometimes work (even after stating it cannot resolve the host) and it will sometimes fail. If I then try a dig for the .local (e.g. ourodserver.local) it also yields the same varied results. However, on every machine that I've tested if I then open a Finder window and navigate to the server via the "Shared" menu and connect I have no trouble connecting and then magically my digs and pings in terminal work. If I revert DNS back to point to our old Windows server the issue goes away. I have meticulously combed through that server many many times now and am not seeing any missed entries. Any idea what could be causing this?

You must have a working DNS service, and the server's hostname must match its fully-qualified domain name. To confirm, select the server by name in the sidebar of the Server application window, then select the Overview tab. Click the Edit button on the Host Name line. On the Accessing your Server sheet, Domain Name should be selected. Change the Host Name, if necessary. The server must have at least a three-level name (e.g. "server.yourdomain.com"), and the name must not be in the ".local" top-level domain, which is reserved for Bonjour.
The primary DNS server used by the server must be 127.0.0.1 (that is, itself) unless you're using another server for internal DNS. The only DNS server set on the clients should be the internal one, which they should get from DHCP if applicable.

Lion server file sharing issue with windows API read/write ini file (GetPrivateProfileString)

Hello,
I try to config lion server as file server for a windows application we use at work. All other computers are windows 7 or XP, lion server is the only mac. I choose lion server because it's size, quality and personal love of apple products.
10.7.2 lion server's samba file sharing works almost perfectly with all my windows machines, I can copy, delete, modify any text files or office files without any issue, but the most important windows application for my business doesn't work with samba file sharing. After some digging, I found it is because windows program can't read or write INI file stored on lion share. Windows API GetPrivateProfileString always returns empty if the INI file is store on lion share.
You can download a small application for read/write windows INI file from codeproject.com to test this problem:
http://www.codeproject.com/KB/files/ini.aspx
I can open/edit the in file using any text editor without any problem. The only problem is with those windows APIs. ACL is turned on for my lion share and assigned "delete" rights to samba users.
I install samba3 on the same server; it works perfectly with windows API. My windows program also works. Looks like there is something wrong with lion server's sambax.
I'd prefer to use built-in samba even I have samba3 working. Built-in samba is very immature right now, but considered how young it is, I will give apple some time to make it mature.
Does anyone have same issue or knows how to fix it?
Thanks,
Michael.

All the memory is fine. The server rarely if ever goes down when there are only around 10-12 users connected. When there are 20+ users connected and working heavily it goes down often. When I say working heavily, I mean they are transferring huge files to the SAN (100GB+), sometimes 5 at a time per user, and there are a bunch of others who are reading large video files at a minimum of 220MB/sec from the SAN.
Though this worked on Snow Leopard without any issues, Lion just doesn't seem to be able to handle it. The odd thing is, on Snow Leopard there was only a single 1GB ethernet connection to a NAS system, whereas with Lion we have a much more powerful machine with a 6-port 10GB ethernet card and a 4 lane 8GB fiber card to a true SAN. You would think that the newer scenario with Lion would handle far more users with ease.
So far, very disappointing with regards to Lion's file serving performance.

SQL 2000 linked server to MSDAORA returns "provider did not ...

Hi, I have a linked server setup in SQL 2000 using "MS OLE DB Provider for Oracle" to connect to a Oracle 9.2 DB on another server.
This works fine apart from when the Oracle database is being backed-up, in which case any query against it returns: -
Step Error Source: Microsoft OLE DB Provider for SQL Server
Step Error DescriptionLE DB provider 'MSDAORA' reported an error. The provider did not give any information about the error. (Microsoft OLE DB Provider for SQL Server (80040e14): OLE DB error trace [OLE/DB Provider 'MSDAORA' IDBInitialize::Initialize returned 0x80004005: The provider did not give any information about the error.].)
This is OK when the backup is running but we could be missing important messages if the Oracle errors are not able to be passed back correctly.
Any help would be much appreciated.
Regards,
Richard

did you find any answers? I have encountered the same problem

UCCX 8.5 Informix/SQL Server linked server question

We have several custom (in-house) queries that were written against a UCCX 7.x installation (SQL Server). These queries were written using a variety of t-sql functions (DATEADD, DATEPART, GETDATE etc). When we migrate to UCCX8.5 (Informix) I'm assuming we will need to translate those t-sql functions to their equivalent Informix functions...is that a correct understanding? Has anyone else faced a similar situation? Any gotchas to share?
Also would be interested to hear from anyone who defined a linked server in SQL Server to the new Informix database server....how did it go, any gotchas there?
Thanks!!!

Hi
That's pretty much it - there are equivalent functions for most things, and the syntax (beyond the basic selects) is quiet different and there are some random restrictions on the structure of queries that I don't think applied in MS SQL. A good way to learn is:
- Comparing the MSSQL and Informix equivalents of the standard UCCX procedures
- The IBM 'boulder' website tends to show up on most searches on google for informix commands and has lots of info on syntax etc.
I find Informix more difficult than SQL as it's less forgiving and you don't get decent tools to debug/verify syntax etc without paying out some money..
I've never had a need to do a linked server.
Regards
Aaron

SQL 2012 Linked Server connection from SQL 2000

Does anyone know if it's possible to create a linked server connection in SQL 2000 to a SQL 2012 instance?
If so, which provider should I use?
Many Thanks,

URL Link to BSP with MVC

Hi,
I have a BSP with MVC design.
I assume that the URL link to the application is the URL I see when I go into the Controller page under the BSP in SE80.
Is that correct?
The problem is that when I take that URL and copy paste it into a web browser, I get the first view but when I click on any button, the controller class is not called.
If I do a right click on the BSP and select the TEST option, all is working perfectly.
Do you have any idea why this is happening or do I do something wrong?
Thanks,
Itay

Hi Stefan,
Same issue i have as well.
My Understanding is, in NWBC desktop, if you open a non sap (eg: html) page, NWBC becomes an IE Browser.
That means you are now out of SAP for that tab (with html page) and whenever you try to launch any SAP transaction (using the method from HTML) it will launch in a new window and ask for Login.
May be Experts like Samuli Kaski & Melinda Ludanyi can put some light on it.
But, I have one more solution for this which is partially working in my case. May be helpful in you case as well.
Issue: From some SAP transaction in NWBC (say tab A), you are launching the html page (say tab B) and then want to launch another SAP transaction (Say tab C) from html.
Solution: Embed the HTML in SAP using HTML Viewer class and launch SAP custom transaction using the interface IF_LSAPI. It will launch it in new tab as a sap transaction with your html page.
Now if you want to launch the SAP transaction from your html page (Which is embedded in SAP custom transaction) you can use HTML Viewer class Events and you can pass parameters as well. Re use the same interface IF_LSAPI and launch it in new tab
In my case i am facing problems as the web developer has so many things on java script and they are not working properly. He is working on it and i am hoping it will be fine.
Regards,
Nik

SQL Query : Order By issue with HUGE Table

Hello friends,
I have been through a terrible issue with order by. I would appreciate your help. Please let me know, your input for my case:
=> if i run select query it returns result quick in some milliseconds. (sql dev. fetches 50 rows at a time)
=> if i run select query with where condition and column (say A) in where condition is even indexed and i have order by and that order by column (say B) is also indexed.
Now, here is the issue:
1. if no. of rows with that where condition can filter yielding small result set then order by works fine .. 1-5 sec which is good.
2.*if no. of rows with that where condition can filter yielding Large result set, say more than 50,000 then with order by then the wait time is exponential.... i have even waited 10+ mins to get the result back for 120,000 records.*
Is order by takes that long for 100K records ... i think something else if wrong... your pointer will really be helpful... i am very new to sql and even newer for large table case.
I am using SQL Developer Version 2.1.1.64
and Oracle Database 11g Enterprise Edition Release 11.1.0.7.0 - 64bit Production
Thank you so much.

Yes you are correct, but my concentration was on order by thing, so it will do full scan of table so i was putting that ... and was also wondering if millions of record in table should not be a issue...???

Hi ABAA101,
According to your description, when you use csv file as data source in SSRS 2012 report, you got the error message.
I tested the issue in my local machine, due to some policy restrictions, I could not install Access in my local machine. To workaround the issue, we can use the connection string like below:
Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\\report;
Extended Properties="text;HDR=Yes;FMT=Delimited"
The csv file is stored in report folder in C driver.
In Query text box in the dataset, we can use the query like below:
Select * from new.csv
If you have any more questions, please feel free to ask.
Thanks,
