Connection string - using alias

I am currently able to connect to Oracle databases using a connect string like:
con = DriverManager.getConnection("jdbc:oracle:thin:@host_name:post:SID", "userid", "password");
Is there away I can connect by just passing the alias of the SID that is in my tnsnames.ora file and not specifying the host and the port? We move instances to different boxes etc. and I would like to avoid hardcoding the hosts and the port. I know you can configure connection strings using the tnsnames.ora file but it just parses it and stores the host,port and SID. Any help would be appreciated.
null

the format that you stated is correct for jdbc thin drivers.
the tnsnames.ora format is supported only with jdbc oci drivers.

MS db Connection String using ASP VBScript and DW8

Hi
My MS db has been working with DW8 followong my use of a connection string in connSci***.asp. My OS is Windows7. This has worked fine.
<%
' FileName="Connection_ado_conn_string.htm"
' Type="ADO"
' DesigntimeType="ADO"
' HTTP="true"
' Catalog=""
' Schema=""
Dim MM_connSciWeb_STRING
MM_connSciWeb_STRING = "DSN=DSN_******"
%>
Now when I update the db and check that the new additional records have been added (and they have been) I can still only access the original records. When I retest the connection string I get the 404 error message.
Can anyone help?
Regards
Kevin

>This has worked fine.
When did it stop working? What changes did you make?
MM_connSciWeb_STRING = "DSN=DSN_******"
Any particular reason you are using DSN rather than DSNless connections?
>Now when I update the db and check that the new additional records have
>been added (and they have been) I can still only access the original records.
Can you explain? How do you know the new records where added if you can't access them?
>When I retest the connection string I get the 404 error message.
How are you testing the connection?

Find Connection String used by SQL Server Management Studio

I am having problems getting my VS C# .NET application to connect to a SQL Server Database, even though I can connect to it (on the same machine) using SQL Server Management Studio.
Is there any way I can find the connection string that SQL Server Management Studio generates when it connects?

Hi,
As you have Visual Studio on your machine, I think we can also use the Visual Database Tools of Visual Studio to generate the connection string.
Please:
1. Create a new data connection to the SQL Server database in the
Server Explorer of Visual Studio
2. After the connection is established, right-click on the connection name and select
Properties. There is an item called Connection String in the
Properties window.

Cannot figure jdbc connection string using LDAP to lookup db

I found only one example of this
"jdbc:oracle:thin:@ldap://ldap.acme.com:7777/sales,cn=OracleContext,dc=com"
My ldap.ora file has this in it:
DEFAULT_ADMIN_CONTEXT = "dc=ba,dc=ssa,dc=gov"
DIRECTORY_SERVERS= (s07a29b.ba.ssa.gov:389:636,s1pta34.ba.ssa.gov:389:636,r24300a.ba.ssa.gov:389:636)
My db is ismarts1
I've tried all variations I can think of and cannot get it to work. Most obvious would be this:
jdbc:oracle:thin:@ldap://s078a9b.ba.ssa.gov:389:636/ismarts1,dc=ba,dc=ssa,dc=gov
but it is not working...
I don't get the 2 port numbers (if that's what they are) in the ldap.ora list of servers.

You've confirmed that it works in sql*plus?
The typical format of the url is
jdbc:oracle:thin:@ldap://[host]:[port]/[database],cn=OracleContext,[dc=...,dc=...]In your case, you might try
jdbc:oracle:thin:@ldap://s078a9b.ba.ssa.gov:389/ismarts1,cn=OracleContext,dc=ba,dc=ssa,dc=govSince you do have multiple ldap servers configured, you can also specify more than one in the url separated by a space.
jdbc:oracle:thin:@ldap://s078a9b.ba.ssa.gov:389/ismarts1,cn=OracleContext,dc=ba,dc=ssa,dc=gov ldap://s1pta34.ba.ssa.gov:389/ismarts1,cn=OracleContext,dc=ba,dc=ssa,dc=govThe 2 port numbers specify the ports ldap listens on, the first being non-ssl and the second being ssl.

Setting up connection using a single connection string.

Post Author: DubbleOh7
CA Forum: Data Connectivity and SQL
I know about the ConnectionInfo object in for .NET crystal reports, but for security purposes we don't have access to a password of any kind, nor do we pass them around our web pages, they are used for login access only. So how can I just set a connection string for the report to access a SQL Server database? I prefer NOT to do the Dataset work around. Its a busy server and the report could contain up to 20,000 records with lots of fields. Not efficient. I also know I could make an object fill it with data from a data reader, but not sure thats as efficient as just having the report execute the stored procedure I have. I also don't want the report to pop up that login page automatically for the users since they have already logged into the website. I'm looking forward to any ideas or suggestions. Thanks in advance for any info or suggestions you may have!
Summary:
I don't want to use datasets due to inefficiency and overhead of several thousand records.
I just want to be able to use a connection string using windows authentication enabled for the report connection to a SQL Server database.
This is for SQL 2K5..calling a stored procedure
Crystal reports for ASP.NET (VB language solutions preferred)
Basically I'd like to use a trusted connection and
ReportConnection.ServerName = "SERVER"
ReportConnection.DatabaseName = "DATABASE"
ReportConnection.IntegratedSecurity = True
doesn't get me there.

C How to Set Isolation Level in the Connection String

How to Set Isolation Level in the Connection String using the "Microsoft OLE DB Provider for DB2 Version 4.0"?
We are trying to move from Crystal Reporting that run against a IBM DB2 database on a mainfram to SSRS reporting and we have downloaded the "Microsoft OLE DB Provider for DB2 Version 4.0" and then worked with the DB2 Administrator to create the
Packages. We only have access to use the "Read Uncommitted ("MSUR001") package. We were able to connect and pull data before he removed access to the other packages, but after setting access the Connection keeps trying to use
the 'Cursor Stability (MSCS001)" package. How do we change the Default to the "Read Uncommitted ("MSUR001") package??? Since it is keeps defaulting to the the other package
we can't connect to do it in the T-SQL query, it has to be set at the Connection String level.

Hi Dannyboy1263,
According to your description, you want to set the Transaction Isolation Level in Connection String. Right?
In Reporting Services, the Connection String for OLE DB Connection can only contains Provider, Data Source and Initial Catalog. There's no property for setting Transaction Isolation Level in the Connection String. Based on my knowledge, we can
only set the Transaction Isolation Level at Query level or set it by using code (C#, VB, Java...) to call the property of Connection. So unfortunately your requirement can't be achieved currently.

How to achieve synchronization after DCP connection string changed via sdk

Hi guys,
i have modified the DCP connection string using method: metaDataProperties.setProperty("SI_METADATA_BVCONN_ATTRIBUTES", new string here) via BOE SDK for java, and then
checked it through Query Builder
:select * from CI_APPOBJECTS where SI_GUID=' DC(DataConnection) GUID' ,
it appears ok, the DCP connection string has been changed.
but the problem is :
when i logon to the infoview or cmc , i find that the information of DCP parameter is still the former one.
(in most cases , it display the old, former con-info, but it also display the correct new data several times )
And if i restart the machine , it will be work ok , infoview will get the latest DCP parameters information.
(related service restarting is of no effect)
how to refresh the latest boe managed information?
Thanks.
Regards,
Jinling.

Not quite what I meant - I was suggesting you load the entity immediately after reading it from PU_B, or anytime before associating it into PU_A, so before the merge. What you have not shown though is any code on how you are obtaining IntegrationDepartment and integrating it into PU_A, or what you mean by it is returning a refreshed version of Topic. This problem could also be the result of how your provider works internally - this is a TopLink/EclipseLink forum post so I cannot really tell you why you get the exception other than it would be expected to work as described with EclipseLink as the JPA provider.
So the best suggestions I can come up with are prefetch your entity, try posting in a hibernate forum, or try using EclipseLink/TopLink so someone here might be better able to help you with any problems that arise.

Database Connection Strings

I been searching online for information on how to setup a
connection string using CFQUERY to connect to a Oracle database. I
been reading that this can be done but I cannot find any
information on constructing a connection string or working examples
for anything besides Microsoft Access or local Microsoft DNS
Database names.
I know ColdFusion can connect. I have the database selected
in "Data & Services > Datasources > Oracle " but at run
time I might need to connect to another Oracle database. Any incite
would be appreciated.

Connection strings, and thus "DSN-less" connections, were
available in CF 5, but no more.

Connection string in dev and production

I have a several servers that i want to pull data from.
I put the connection string in a OBJECT variable that come from configuration table and use it in the for loop mapping the value to local variable called connectionstring, this variable is the expression for the connection string property.
So far everything is working as expected.
my problem is that on my development i put my local server in the connection string variable so i will be able to connect to the server so i will be able to map source to destination.
When i deploy the solution to production the data in the configuration table is different obviously but i get a connection error that saying that it try to connect to my dev server.
Any idea why?
Thanks.

Seems like you haven't configured your package properly
Here are some important consideration for SQL Server Configuration
Now, let’s go through some important considerations that will help you to understand this configuration type better, and to avoid common implementation issues:
SQL Server configurations are very flexible, as you can store multiple configuration properties/values in the same table.
Multiple packages can use the same configuration table and filter.
You can have a configuration filter for each entry in the configuration table, or you can use the same filter to group a set of entries. If you use the second approach, make sure that all properties under the selected filter exist in the package
being configured. Otherwise warning messages are generated for those properties in the configuration filter that do not exist in the target package.
You can use existing database security and backup policies to protect the configuration table contents.
A drawback of this configuration type is that it relies on an SSIS connection manager to get access to the configuration table, but does not have built-in support for updating its connection string. In other words, the connection string that points
to the configuration table is hard-coded inside of the package, and you have to take extra steps in order to update it (for example, through an extra package configuration placed at the top of the Package Configurations Organizer, or in SQL Server 2008, by
using the /CONN option of DTExec).
The /CONN option of DTExec utility can be used to override the connection string used by the configuration only in SSIS 2008. This is because SQL Server 2008 Integration Services reloads configurations after applying DTExec command line options.
The configuration wizard can create the table and insert the required rows when they do not exist, but only if the direct method is chosen. The wizard never includes any sensitive data in the ConfiguredValue column of the table, and you would need
to manually update the table to add the required sensitive data.
If you use the direct method, and provide an existing configuration filter, the wizard will prompt you to either reuse the configuration information in the table or to override it with the property values from the current package. Make sure that
you understand this behavior, since choosing the wrong option could change the contents of the configuration table and produce unexpected execution results.
When you use the indirect method, the environment variable must contain the name of the configuration connection manager, the name of the configuration table and the configuration filter. The syntax should be:
“ConfigurationManagerName”;”Schema.ConfigurationTableName”;’ConfigurationFilter”
As with the direct method, you have to account for extra logic if you need to modify the connection string inside of “ConfigurationManagerName”

Hide DB Connect- String or use alias?

Hello,
maybe the question is answered anywhere, but i found nothing. Maybe i am just to stupid??
I call a report from an external application with an url like these:
http://servername.com/reports/rwservlet?desformat=pdf&server=report_servername&report=reportname.rdf&userid=dbuser/password@database&destype=cache&parameter1=50114000
So, now i want to hide the database- connect- string somehow. Maybe i have to use an alias.
But where i can specify an alias?
So, i want the url looks like that:http://servername.com/reports/rwservlet?desformat=pdf&server=report_servername&report=reportname.rdf&userid=alias1&destype=cache&parameter1=50114000
Is these possible??
Thanks a lot for fixes or suggests.

Hi,
Use the method as post.
Nothing will be exposed in the URL.
Is it nesseary to show the values in the URL ?

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.Rows.Item(1).HorizontalAlignment = $xlCenter
$excel.Rows.Item(1).VerticalAlignment = $xlTop
$excel.Rows.Item("1:1").Font.Name = "Calibri"
$excel.Rows.Item("1:1").Font.Size = 11
$excel.Rows.Item("1:1").Font.Bold = $true
$filename = "D:\Script\Reports\Status_$a.xlsx"
if (test-path $filename ) { rm $filename }
$wb.SaveAs($filename, $xlOpenXMLWorkbook) #save as an XML Workbook (xslx)
$wb.Saved = $True #flag it as being saved
$wb.Close() #close the document
$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:
PowerShell and Excel: Fast, Safe, and Reliable
If there is anything else regarding this issue, please feel free to post back.

I am using the visual studio 2012 coded UI test, i added the following connection strings to connect to an excel data source:
[DataSource("System.Data.Odbc", "Dsn=Excel Files;Driver={Microsoft Excel Driver (*.xls)};dbq=C:\\Users\\shaza.said.ITWORX\\Desktop\\Automation\\On-track Automation Framework\\On-track_Automation\\Automation data file.xls;defaultdir=.;driverid=790;maxbuffersize=2048;pagetimeout=5;readonly=true",

Thanks for Adrian's help.
Hi shaza,
From the error message, I suggest you can refer the Adrian's suggestion to check the date source connection string correctly.
In addition, you can refer the following about how to Create a Data-Driven Coded UI Test to check your issue:
http://msdn.microsoft.com/en-us/library/ee624082.aspx
Or you can also try to use a Configuration File to Define a Data Source for coded UI test.
