Failover connection string

hi all!
can i put a connection string in the tns file so that the users don't have to change the connection string in the event of failover by the dataguard..
i mean can i have the same connection string for the primary database and the standby database????

Yes, you can.
Look for 'failover=on' in the Net administrators documentation.

Connection string in listener log file for loading balance/failover

Hi Experts,
I have 4 node RAC for oracle 10g2 in rad hate 5.0
We creaed service dbsale ( sale1,2 as pr imary and sale3/4 as available) with loading balance/failover.
The remote user created a local TNS as
localmarket =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 155.206.xxx.xx)(PORT = 1521))
(LOAD_BALANCE = OFF)
(CONNECT_DATA = (SERVICE_NAME = dbsale))
From server side, I saw that user send two request connection string. one fail and another is OK.
It seems that fail connecting come from failover/loading balance from dbsale3?
Why do we get two connection string in listener log file?
Which difference is between two connection string?
Where does system change these connection string?
Thanks for your explaining.
Jim

Hi Jim,
I think the best way on this case is create one service with one instance as primary and another 3 as available.
Or use the connect string with two vip addresses, cause the service has two instances and the tnsnames.ora entry has only one.

Adworker using wrong JDBC connect string during upgrade to 12.1.3

Our env
APPS - 12.1.2 - running on SLES 11
DB 11.2.0.3 - running on IMB System z
We cloned PROD to a new host (instance was previously on DB host - debsdb01 and app host debsap03)
The clone was made to debsdb04 - and app was reconfigured on debsap03
I got the app to start up and run before taking it down to apply the 12.1.3 patch.
However, in the process of the 12.1.3 patch, I see the following entry in the ADworker log files.
JDBC connect string from AD_APPS_JDBC_URL is
(DESCRIPTION=(ADDRESS_LIST=(LOAD_BALANCE=YES)(FAILOVER=YES)(ADDRESS=(PROTOCOL=tcp)(HOST=hostname1.companyname.com)(PORT=1549)))(CONNECT_DATA=(SID=DEV3)))
where as it should be
JDBC connect string from AD_APPS_JDBC_URL is
(DESCRIPTION=(ADDRESS_LIST=(LOAD_BALANCE=YES)(FAILOVER=YES)(ADDRESS=(PROTOCOL=tcp)(HOST=hostname4.companyname.com)(PORT=1535)))(CONNECT_DATA=(SID=DEV3)))
If I do an echo $AD_APPS_JDBC_URL on debspap03, it returns
JDBC connect string from AD_APPS_JDBC_URL is
(DESCRIPTION=(ADDRESS_LIST=(LOAD_BALANCE=YES)(FAILOVER=YES)(ADDRESS=(PROTOCOL=tcp)(HOST=hostname4.companyname.com)(PORT=1535)))(CONNECT_DATA=(SID=DEV3)))
Where are the ADWORKERS getting the old value of the DB host name?
Any help would be appreciated.
Thanks

I believe figured out what the issue was.
I was (am) running the patch session from a VNC session that was established during the previous version of this instance - so the previous connect string was being used.
Once I killed the old VNC session and established a new one, I was able to retrieve the correct value for $AD_APPS_JDBC_URL from the command prompt.
Yes - the value of the $AD_APPS_JDBC_URL was showing the old value in the old VNC session.
Thanks for all of your input esp on a Saturday - when I thought I would have to wait until Monday to get this figured out.

Connection string question

Application used to connect to 9i single instance DB using
jdbc:oracle:thin:@host:1521:dbname
Is there a way to connect to RAC without having to specify all the host names in the cluster like below? Want to be able to specify only one host name. The OS (linux) doesn't have a cluster name which could be used- at least not that I know of. It will require a lot of changes to ask user for multiple names if using RAC and hoping there is a simple way to connect without having to re-write the UI to get all the host names. I know if I use sqlplus directly, I can connect just by specifying the service name and not listing the host names. How does sqlplus get all the host names? By reading tnsnames.ora? We want to be able to get failover capabilities and hoping there is a way to specify a single host name (or cluster if there is such a name) in the connection string. Oracle client sw has been installed on the application server.
String below requires all the host names:
jdbc:oracle:thin:@(DESCRIPTION=
(LOAD_BALANCE=on)
(ADDRESS=(PROTOCOL=TCP)(HOST=db7-vip)(PORT=1521))
(ADDRESS=(PROTOCOL =TCP)(HOST=db6-vip)(PORT=1521))
(ADDRESS=(PROTOCOL=TCP)(HOST=db5-vip)(PORT=1521))
(CONNECT_DATA=(SERVICE_NAME=<service_name>)))
.

If you want to connect using failover characteristics, then the standard thin client should be replaced by the oci client, and instead of specifying the hostname:port:sid on the URL, you can use a tns entry. All connectivity, failover, and load balancing characteristics can be specified within the tns entry.

How to specifiy the provider to be Oracle.ManagedDataAccess.Client when creating a dynamic connection string with EF Code First from Database?

I am trying to use the relatively new Code First from Database with the newest EF (6.x) and on an Oracle database (11g, but I have installed the newest ODTwithODAC). First of all, it works fine as long as the connection string is inside the App.Config file. But when I try to build it dynamically in the C# code (or rather, statically at the moment) it fails. I have it working with a dynamically built connection string when doing Model from Database though, so I'm at a loss right now.
First, I have created a second constructor for the context class that takes a string and does base(connectionString). Then I build the connection string via
OracleConnectionStringBuilder oracleBuilder = new OracleConnectionStringBuilder();
oracleBuilder.DataSource = "TEST.BLA.COM";
oracleBuilder.UserID = "ABC";
oracleBuilder.Password = "abc";
oracleBuilder.PersistSecurityInfo = true;
string connection = oracleBuilder.ToStrin();
Now trying to open an EntityConnection by giving to it this provider-specific connection string (or even the static one from the App.Config) doesn't work; I get "keyword not supported: user id"). Trying it by creating a context and giving this connection string doesn't work either. I'm pretty sure that this is because I didn't specify the provider to use; after all, it should use the Oracle.ManagedDataAccess.Client provider and not an SQL Server based one.
I then tried to get around this by using an EntityConnectionStringBuilder on top and specifying the provider keyword there, but then I get "keyword not supported: provider" when using it in the context constructor, and "the 'metadata' keyword is always required" when using it with the EntityConnection constructor.
As I said above: I bet it's the provider that I have to specify somehow, but I don't know how. The code that does work is the following:
using (var context = new Model())
context.Database.Connection.Open();
context.Database.Connection.Close();
When I read context.Database.Connection.ConnectionString, it is exactly the provider-specific connection string I created above, but I don't know where to specify the provider again. Do you know of any way to do this? Certainly there must be one.
PS: I have also posted this question on http://stackoverflow.com/questions/27979454/ef-code-first-from-database-with-managed-oracle-data-access-dynamic-connection because it is quite urgent and I'd like to use Code First from Database. Otherwise I'd have to go "back" to using Model from Database again, which is not ideal because we have updatable views where the .edmx-file has to be edited after every reload of the model, while with Code First from DB inserting into the view automatically works.

How to dynamically set connection string for report in C# code?

Hi,
I have installed CRVS2010. I have created new Crystal Report WPF Application and new report. I would like to set connection string for report in code dynamically.
Is this possible?
Thanks
Ivana

Lots of posts in this forum on how to set database connections. WPF should not be a consideration as it's just a viewer. The report engine is still the same. Search these forums. Use the search box at the top right corner of this page. Look at samples here:
https://wiki.sdn.sap.com/wiki/display/BOBJ/CrystalReportsfor.NETSDK+Samples
Note that none of the samples above are using WPF, but like I said, the WPF is just a different viewer and will not impact how the report engine logs on to a database. (I think of it as a gray car vs. a red car. Same engine, just the color is different)

how can we reproduce what you claim?

I run Dev 6i on Windows 2008 R2 64-bit,the forms are working fine after connection to the database but the reports continue to request for username, password and database connection string every time i try to open a report.

I receive REP-0501: Unable to connect to specified database. I run developer 6i application on windows 2008 r2. I have applied the nn60.dll and nnb60.dll files to the \BIN directory. The forms are working fine. The reports will only display after the correct user id (username, password and database connection string) is supplied. This is happening to all attempts to open already complied form. Pls, help.

If you are connecting to an Oracle 11g database, remember that by default the passwords are case sensitive. To disable that, run
ALTER SYSTEM SET SEC_CASE_SENSITIVE_LOGON = FALSE;

Powershell use Connection String to query Database and write to Excel

Right now I have a powershell script that uses ODBC to query SQL Server 2008 / 2012 database and write to EXCEL
$excel = New-Object -Com Excel.Application
$excel.Visible = $True
$wb = $Excel.Workbooks.Add()
$ws = $wb.Worksheets.Item(1)
$ws.name = "GUP Download Activity"
$qt = $ws.QueryTables.Add("ODBC;DSN=$DSN;UID=$username;PWD=$password", $ws.Range("A1"), $SQL_Statement)
if ($qt.Refresh()){
$ws.Activate()
$ws.Select()

$Excel.Quit() #and the instance of Excel
$wb = $Null #set all variables that point to Excel objects to null
$ws = $Null #makes sure Excel deflates
$Excel=$Null #let the air out
I would like to use connection string to query the database and write results to EXCEL, i.e.
$SQL_Statement = "SELECT ..."
$conn = New-Object System.Data.SqlClient.SqlConnection
$conn.ConnectionString = "Server=10.10.10.10;Initial Catalog=mydatabase;User Id=$username;Password=$password;"
$conn.Open()
$cmd = New-Object System.Data.SqlClient.SqlCommand($SQL_Statement,$conn)
do{
try{
$rdr = $cmd.ExecuteReader()
while ($rdr.read()){
$sql_output += ,@($rdr.GetValue(0), $rdr.GetValue(1))
$transactionComplete = $true
catch{
$transactionComplete = $false
}until ($transactionComplete)
$conn.Close()
How would I read the columns and data for $sql_output into an EXCEL worksheet. Where do I find these tutorials?

Hi Q.P.Waverly,
If you mean to export the data in $sql_output to excel document, please try to format the output with psobject:
$sql_output=@()
do{
try{
$rdr = $cmd.ExecuteReader()
while ($rdr.read()){
$sql_output+=New-Object PSObject -Property @{data1 = $rdr.GetValue(0);data2 =$rdr.GetValue(1)}
$transactionComplete = $true
catch{
$transactionComplete = $false
}until ($transactionComplete)
$conn.Close()
Then please try to use the cmdlet "Export-Csv" to export the data to excel like:
$sql_output | Export-Csv d:\data.csv
Or you can export to worksheet like:
$excel = New-Object -ComObject Excel.Application
$excel.Visible = $true
$workbook = $excel.Workbooks.Add()
$sheet = $workbook.ActiveSheet
$counter = 0
$sql_output | ForEach-Object {
$counter++
$sheet.cells.Item($counter,1) = $_.data1$sheet.cells.Item($counter,2) = $_.data2}
Refer to:

How do I create a connection string to sql server?

Hi All,
I am currently connecting to a SQL Server via ODBC DSN connection. I am wondering how do I create a connection string directly to a sql server without a DSN connection?
Thank you in advance.

If you have SQL Server or client installed in your machine you can directly connect to SQL server using native connection. When you create new report you can see the option create new connection, here you can see SQL Server. Expand it and enter the connection details where you will be directly connected to SQL Server without ODBC connection.

Raghavendra

Changing Connection String dynamically at runtime

I am using the Crystal Report Viewer control in in a Visuall Studio 2008 C# project. The reports are created inside of Visual Studio 2008, and will be running against an InterSystems Cache database. I have to use an ODBC (RDO) connection and use a connection string.
I have seen many examples of how to update the connection string at runtime if it is SQL server (or some flavor thereof), but nothing for an ODBC (RDO) connection to a NON-MSSQL database.
The problem when I update the connection string for each of the tables in the report, the report will either not run and display a window -- tiled 'Datbase Login' -- that has the Server, Database, Username, and Password fields on the window, OR, it will run but not against the database that was specified at runtime (it uses the connection stored in the report).
Code Sample #1 (This is using the connection string, and will cause a the "Database Login" window to be displayed - the first scenario from above)
rd = new ReportDocument();
// Load the report
rd.Load(fileName, OpenReportMethod.OpenReportByDefault);
rd.Refresh();
// Create the connection object
ConnectionInfo connectionInfo = CreateConnection(Server, Port, ServerNamespace, Username, Password);
// Set the connection info on each table in the report
SetDBLogonForReport(connectionInfo, rd);
SetDBLogonForSubreports(connectionInfo, rd);
private static ConnectionInfo CreateConnection(string Server,
                                               int Port,
                                               string ServerNamespace,
                                               string Username,

I have also tried setting connectionInfo.ServerName equal to just the real server name, but that didn't work either.
After the above operations are performed, I simply assign the returned ReportDocument object to the Crystal Viewer control. If I don't call the above functions, and just set the ReportDocument source (using whatever connection string was embedded in the report originally), the report runs as expected. Only when I attempt to update the connection string, the report will not execute. Please advise. Thanks!

I am using the Crystal Report Viewer control in in a Visuall Studio 2008 C# project. The reports are created inside of Visual Studio 2008, and will be running against an InterSystems Cache database. I have to use an ODBC (RDO) connection and use a connection string.
I have seen many examples of how to update the connection string at runtime if it is SQL server (or some flavor thereof), but nothing for an ODBC (RDO) connection to a NON-MSSQL database.
The problem when I update the connection string for each of the tables in the report, the report will either not run and display a window -- titled 'Datbase Login' -- that has the Server, Database, Username, and Password fields on the window, OR, it will run but not against the database that was specified at runtime (it uses the connection stored in the report).
Code Sample #1 (This is using the connection string, and will cause a the "Database Login" window to be displayed - the first scenario from above) -- The code samples appear to be too long to post, so I will add them as seperate replies.
rd = new ReportDocument();
// Load the report
rd.Load(fileName, OpenReportMethod.OpenReportByDefault);
rd.Refresh();
// Create the connection object
ConnectionInfo connectionInfo = CreateConnection(Server, Port, ServerNamespace, Username, Password);
// Set the connection info on each table in the report
SetDBLogonForReport(connectionInfo, rd);
SetDBLogonForSubreports(connectionInfo, rd);
private static ConnectionInfo CreateConnection(string Server, int Port, string ServerNamespace, string Username, string Password)
        ConnectionInfo connectionInfo = new ConnectionInfo();

        connectionInfo.IntegratedSecurity = false;
        connectionInfo.UserID = Username;
        connectionInfo.Password = Password;        //In examples that I have seen, this is the actual connection string, not just the server name
        connectionInfo.ServerName = connString;          connectionInfo.DatabaseName = ServerNamespace;

Hi,
I have copied a number of SSID packages from a live server to my test server and am trying to get them up and running but I have a problem with the connection. The only thing that is different is the server name. I decided to keep the same connection in the connection manager as it is referenced in a dtsConfig file. I changed the dtsConfig file to reference the new servername [Data Source= new test server name]. I also check my paths and they are pointing to the correct config locations etc.
I found this post which was similar to my problem but I still get problems with the connection
http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=1319961&SiteID=1
I updated the connection by changing the server name in the actual connection. I did this from the data flow tab in the Connection Managers sections (MS Visual Studio). Right clicked - Edit - changed the name of the server name to my test server and selected the database. Test connection was fine, and saved this.
Once I saved this, the connection string changed to my current test server in the properties of the connection. However when I run the package I get the following error:
Error: 0xC0202009 at ReportsImport, Connection manager "myconnectionstring": SSIS Error Code DTS_E_OLEDBERROR.  An OLE DB error has occurred. Error code: 0x80004005.

There may be error messages posted before this with more information on why the AcquireConnection method call failed.

Error: 0xC0024107 at Myprocess import from file: There were errors during task validation.
So even if I change the existing connection properties and save and Build my package again, my connection properties (connectionstring, servername etc) all revert back to its original data source when I re-open the package. Simply it does not seem to be saving the connection properties i put in.
What am I doing wrong or how can I change the existing connection manager to look at the new server. The database is the same and I have full admin privilege on the server.
I don't want to recreate my packages as there are alot and they are not simple.
After changing the connection properties, saving and reloading I get a connection error. But this is because it is not retaining the new connection manger setting i entered.
Incidentally - I created a new SSID to perform a simple connection and write to the the server and it was OK so there is no problem with actually seeing the my test server.
Thanks in advance

Yes, the package is in visual studio and I have executed it. There are no errors but in the output i have the error message about my connection. My dtsConfig file is added to the project in the 'Package Configuration Organizer' and path and files are correct. This is the output error:
Error: 0xC020801C at xx import from file, xxReportsImport [79]: SSIS Error Code DTS_E_CANNOTACQUIRECONNECTIONFROMCONNECTIONMANAGER. The AcquireConnection method call to the connection manager "myconnectionname" failed with error code 0xC0202009. There may be error messages posted before this with more information on why the AcquireConnection method call failed.
I will try and run it using dtexec.exe. if I have two config files do i use
dtsexec.exe /f <packagename> /conf <configfile> /conf <secondconfigfile>

I have been using an app developed in VB.net for accessing the Oracle Lite Database from the client machine. Can anyone please help me out how to set the Connect String in the config file of my front end app to access the Oracle Lite Database from my client machine. Do anyone have the syntax of the connect string to access the lite database in client machine.
Thanks a lot in advance.

Can't change the connection string of SSIS package with derived columns?

We upgraded SQL server 2008 to 2012, copied and converted all SSIS packages from Visual Studio 2008 to 2010. When I opened a package in VS 2010 and tried to change the connection string, in the local connection managers, if the data source is another
SSIS package B(.dtsx file) with derived columns, I can't change the connection string of package B. When I opened the file connection manager editor for package B and tried to locate a dtsx file in another location, saved the change, reopened the project.
Package B still pointed to previous file. Other packages without derived columns work fine. Any thoughts?

We are using the package deployment model and refer to other packages in the same project. If
we changed the path of package B (with derived columns) to "D:\Visual Studio 2010\xxxx", and refer it in package A, in the A's connection manager, the connection string of package B is still its previous location "D:\Visual
Studio 2008\xxxx". When we ran the package A in the SQL server agent, the data source is still
"D:\Visual
Studio 2008\xxxx", so how can I change it to "D:\Visual
Studio 2010\xxxx"? Why has the package C (without derived columns) no such problem? thanks.
