Transação distribuida no SQL Server

July 10, 2013, 10:18 am

Boas!!

Sou iniciante em banco de dados e estou com uma duvida. Tenho uma integração para fazer com outra base de dados (pra ser específico é o OpenEdge Progress), e para fazer a integração entre SQL Server x Progress estou usando LInkedServer.

Para fazer um select ou insert, faço a seguinte instrução:

INSERT OPENQUERY("linked-banco", 'SELECT id FROM PUB."tabela" ') VALUES (4)

Fazendo via comando eu consigo normalmente. Só que eu necessito fazer isso via TRIGGER. Se eu montar uma trigger com essa instrução ele retorna um erro dizendo:

"The operation could not be performed because OLE DB provider "MSDASQL" for linked server "linked-banco" was unable to begin a distributed transaction."

Alguem pode me ajudar se há alguma forma de eu "desativar" essa transação distribuida, ou conseguir passar isso?

Duda general C#

Buenas, estoy haciendo un programa simple en C# que utilizaría en la empresa para hacer consultas en SQL Server y al dar click en "consultar" muestre los resultados. La complicación es que el query depende de lo que quiere consultar el usuario, para ser más claro dejo el código:

#region CNX STRING
                    cnx.Open();
                    string query = "SELECT " + comboBoxDato.SelectedItem.ToString() +
                           " FROM " + comboBoxBase.SelectedItem.ToString() +
                           " WHERE letra='" + textBoxLetra.Text +
                           "' and " + comboBoxDatoDesc.SelectedItem.ToString() +
                           "='" + textBoxValDato.Text + "'";
                    SqlCommand cmd = new SqlCommand(query, cnx);
                    cmd.ExecuteNonQuery();
                    cnx.Close();
                    #endregion

Se me complica cuando tengo que mostrar el resultado en la DataGridView, probé de muchas maneras, ninguna dio resultados. Espero su pronta ayuda!

writing data to the same table from several sources in parallel

Hello,

a vbscript reads out the eventlog of a server and writes the data into a sql dtabase:

Set objConn = CreateObject("ADODB.Connection")
Set objRS = CreateObject("ADODB.Recordset")

strSQLStmt = "SELECT * FROM tbl_eventlog"
strConn = "Provider=SQLOLEDB;server=srv001;uid=sqluser;pwd=password;Initial Catalog=DB-Eventlog;"
objConn.Open strConn
objRS.CursorType = adOpenKeyset
objRS.Open strSQLStmt, strConn, 3, 3

strComputer = "."
Set objWMIService = GetObject("winmgmts:" & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
Set colItems = objWMIService.ExecQuery("SELECT * FROM Win32_NTLogEvent WHERE  LogFile <> 'Security'")

 For Each objItem In colItems

	objRS.AddNew
	      objRS.Fields("RecordNumber").Value = objItem.RecordNumber
	      objRS.Fields("Logfile").Value = objItem.Logfile
	      objRS.Fields("ComputerName").Value = objItem.ComputerName
	      objRS.Fields("EventCode").Value = objItem.EventCode
	      objRS.Fields("Message").Value = objItem.Message
	      objRS.Fields("SourceName").Value = objItem.SourceName
	      objRS.Fields("TimeGenerated").Value = objItem.TimeGenerated
	      objRS.Fields("Type").Value = objItem.Type
	      objRS.Fields("User").Value = objItem.User
	objRS.Update
Next

objRS.Close

When I start the script at several servers one after the other it works as it should so far. But if the script has been started via scheduled tasks at the same time data won't be written to the table.

How can I achieve that data is written in parallel?

Thanks in advance

What all way should we attempt to get this right ?

I have not done any specific configuration in SQL Server.
I turned off all Windows Firewall on Windows 8 for testing purpose. Firewall on server is off too.

I have now create ODBC connection in Windows 8.

-Authentication is SQL login with "test"
-Default settings with other configuration

Then I clicked "Test Data Source" and error occured. Why?

Max login/logout for sql user but not for windows user?

We are migrating from 1 server 2003 iis6 + sql 2000 to 2 server with server 2003 iis 6 and server 2008 R2 with sql 2012 so only the sql server moves ...

We are facing a problem. We use an old connection string oledb with uid/pass.
This works fine until we do about 1000 login/logouts within 1 minute.
(then we get an acces denied)
With the use of an windows account we don't have this problem but with a sql user we do.
(turning off firewall doesn't help)
We tried alot of properties on the sql 2012 server but nothing seems to help.

Is there a way to increase the possible number of login/logouts for an sql user??
Remark : we don't want to change anything on the 2003 IIS6 server

SQLSRV for 64bit PHP: now that there is an official x64 release, when can we start connecting to sql server?

Now that there has been a 64bit release from the official PHP source, is there a 64bit sqlsrv driver?
If not quite yet, what's the lead time?

$0.02: As a little side note, ahuge portion of web dev's on a MS OS run WAMPSERVER, which has had a 64bit version foryears now.  Personally, I've steered projects away from MS DB solutions countless times just to avoid the hassle of rebuilding my dev env ... and I have no delusions about being something special ... ifI'm doing it, surely there are countless other dev's out there doing the same:)    I've always found it ironic that I can only use a MS storage product from mynon-MS OS's.

Anyhow ... back to the topic at hand.
Although the first release of php64 from the official source is for v5.5, please consider that many dev's have many projects in other (older) versions. Personally, I've got plenty of code base in 5.4.

A speedy reply would be greatly appreciated.
I have a project on the block right now, and MS sqlsrv is the requested DB.
If I don't need to worry about steering this one away from MS sql server too, that'd be nice ... just one less thing on my hit list.

I have a project in VS 2010 that connects to a SQL Database. I have moved my sql files and project to a laptop. In VS 2012 you can create a database by going to the SQL Server Object Explorer and right clicking "DataBases" and click "Add New DataBase", there is no option to connect to an existing database.

In my instance I need to connect to a database that already exists. How do I do that?

Error on Open command using SQLConnection

Hi people,

I got two Vb.Net applications that connects to the exact same server, using the exact same code, just in different Data Bases... I use a Connection String like this:
"Data Source=xx.xxx.xx.xxx;Initial Catalog=ibptax;Persist Security Info=True;User ID=sa;Password=xxxxx"
(obs.: I'm using 'sa' user to guarantee that is not an user access problem)

In the vc.Net code I use:
        Dim con As New System.Data.SqlClient.SqlConnection
        con.ConnectionString = strConex
        con.Open()

this way, in the first Application, works very fine...

For some reason that I can't understand, in the second application I got the exact same code, doing the exact same thing, to the exact same SQL Server, only another DataBase, both applications using "sa" user, but it doesn't work...
Using my proxy to collect what is going out of my machine, in the second application when execute con.Open the application tries to do something using 445 port and the server than returns error...

Somebody knows what It can be?

How to install JDBC driver Microsoft sqljdbc.jar in tomcat 7

I want to know if it is possible to use this JDBC driver with Tomcat 7.

If so, how do I input the server.xml, web.xml(WEB-INF), and context.xml(WEB-INF) ?

Here is my context.xml...

<Context>
  <Resource name="jdbc/Contacts"
            auth="Container"
            type="javax.sql.DataSource"
            username="E-Mail Address"
            password="Last Name"
            driverClassName="com.microsoft.sqlserver.jdbc.SQLServerDriver"
            url="jdbc:sqlserver://localhost;DatabaseName=mydb;SelectMethod=cursor;"
            maxActive="8"
            />
</Context>

Here is what I have in my web.xml .

   <security-constraint>
      <display-name>My First Application Security Constraint</display-name>
      <web-resource-collection>
         <web-resource-name>First App Protected Area</web-resource-name>
         <!-- Define the context-relative URL(s) to be protected -->
         <url-pattern>/jsp/security/protected/*</url-pattern>
         <!-- If you list http methods, only those methods are protected -->
         <http-method>DELETE</http-method>
         <http-method>GET</http-method>
         <http-method>POST</http-method>
         <http-method>PUT</http-method>
      </web-resource-collection>
      <auth-constraint>
         <!-- Anyone with one of the listed roles may access this area -->
         <role-name>somename</role-name>
         <role-name>role1</role-name>
      </auth-constraint>
    </security-constraint>

    <!-- Default login configuration uses form-based authentication -->
    <login-config>
      <auth-method>FORM</auth-method>
      <realm-name>Example Form-Based Authentication Area</realm-name>
      <form-login-config>
        <form-login-page>/jsp/security/protected/login.jsp</form-login-page>
        <form-error-page>/jsp/security/protected/error.jsp</form-error-page>
      </form-login-config>
    </login-config>
       
    <!-- Security roles referenced by this web application -->
    <security-role>
      <role-name>role1</role-name>
    </security-role>
    <security-role>
      <role-name>somename</role-name>
    </security-role>

I assume something must be put in the server.xml but im not sure what.

Here is what I have....

      <Realm className="org.apache.catalina.realm.LockOutRealm">
        <!-- This Realm uses the UserDatabase configured in the global JNDI
             resources under the key "UserDatabase".  Any edits
             that are performed against this UserDatabase are immediately
             available for use by the Realm.  -->
        <!-- <Realm className="org.apache.catalina.realm.UserDatabaseRealm"
               resourceName="UserDatabase"/> -->
         <Realm className="org.apache.catalina.realm.DataSourceRealm"
  dataSourceName="jdbc/Pubs"
  userRoleTable="RolesTable" roleNameCol="Role Name"/>
         userTable="Contacts" userNameCol="E-mail Address" userCredCol="Last Name"/>
      </Realm>

What am I missing??? I have placed the sqljdbc.jar file in the tomcat/lib directory. Tomcat accepts

the file by starting the application. I am using form based authentication. I have basically used the

tomcat form example which includes other stuff that needs to be used to authenticate the app. If you

look at the web.xml you can see that access to the app will only take place by accessing the login

form. Then it will access any form on the web app. The form continually loops if it does not find an

entry or even if the db is not working.

SQLOLEDB and SQL Server 2014

I know that the Microsoft OLE DB Provider for SQL Server (SQLOLEDB) has been deprecated,
but I would like to understand if the new incoming SQL Server 2014 will yet allow to create connections using SQLOLEDB.

I expect that new feature will be not supported, but may existing legacy applications continue to access to database created on SQL Server 2014 using old schema ?
Do you know if SQLOLEDB will be removed on new server OS or we may continue to use/install it ?

Thanks in advance.

SQL server error password mismatch sometimes

We have an application that connects to a MSSQL 2005 database using a generic login.  On 64bit Windows 7 machines users get a series of 'can't connect to database' errors after a period of inactivity in the software, usually around 15 minutes or so.  If they cancel the program and log back in it always connects and works fine (unless they are inactive for awhile again).  On the server we are seeing the "Error: 18456, Severity: 14, State 8" error in the logs which indicates a password mismatch but as I noted above, if the user cancels the program and logs back in, using the same credentials, it connects just fine.  This does not happen on WinXP or 32bit Win7 machines.  Any help would be greatly appreciated.
