Replicate HCL Domino Data from PowerShell
Write a quick PowerShell script to query HCL Domino data. Use connectivity to the live data to replicate HCL Domino data to SQL Server.
The CData ODBC Driver for HCL Domino enables out-of-the-box integration with Microsoft's built-in support for ODBC. The ODBC driver instantly integrates connectivity to the real HCL Domino data with PowerShell.
You can use the .NET Framework Provider for ODBC built into PowerShell to quickly automate integration tasks like replicating HCL Domino data to other databases. This article shows how to replicate HCL Domino data to SQL Server in 5 lines of code.
You can also write PowerShell code to download HCL Domino data. See the examples below.
Create an ODBC Data Source for HCL Domino
If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.
Connecting to Domino
To connect to Domino data, set the following properties:
- URL: The host name or IP of the server hosting the Domino database. Include the port of the server hosting the Domino database. For example: http://sampleserver:1234/
- DatabaseScope: The name of a scope in the Domino Web UI. The driver exposes forms and views for the schema governed by the specified scope. In the Domino Admin UI, select the Scopes menu in the sidebar. Set this property to the name of an existing scope.
Authenticating with Domino
Domino supports authenticating via login credentials or an Azure Active Directory OAuth application:
Login Credentials
To authenticate with login credentials, set the following properties:
- AuthScheme: Set this to "OAuthPassword"
- User: The username of the authenticating Domino user
- Password: The password associated with the authenticating Domino user
The driver uses the login credentials to automatically perform an OAuth token exchange.
AzureAD
This authentication method uses Azure Active Directory as an IdP to obtain a JWT token. You need to create a custom OAuth application in Azure Active Directory and configure it as an IdP. To do so, follow the instructions in the Help documentation. Then set the following properties:
- AuthScheme: Set this to "AzureAD"
- InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to avoid repeating the OAuth exchange and manually setting the OAuthAccessToken.
- OAuthClientId: The Client ID obtained when setting up the custom OAuth application.
- OAuthClientSecret: The Client secret obtained when setting up the custom OAuth application.
- CallbackURL: The redirect URI defined when you registered your app. For example: https://localhost:33333
- AzureTenant: The Microsoft Online tenant being used to access data. Supply either a value in the form companyname.microsoft.com or the tenant ID.
The tenant ID is the same as the directory ID shown in the Azure Portal's Azure Active Directory > Properties page.
Connect to HCL Domino
The code below shows how to use the DSN to initialize the connection to HCL Domino data in PowerShell:
$conn = New-Object System.Data.Odbc.OdbcConnection
$conn.ConnectionString = "DSN=CData Domino Source x64"
Back Up HCL Domino Data to SQL Server
After you enable caching, you can use the code below to replicate data to SQL Server.
Set the following connection properties to configure the caching database:
CacheProvider: The name of the ADO.NET provider. This can be found in the Machine.config for your version of .NET. For example, to configure SQL Server, enter System.Data.SqlClient.
CacheConnection: The connection string of properties required to connect to the database. Below is an example for SQL Server:
Server=localhost;Database=RSB;User Id=sqltest;Password=sqltest;
The SQL query in the example can be used to refresh the entire cached table, including its schema. Any already existing cache is deleted.
$conn.Open()
# Create and execute the SQL Query
$SQL = "CACHE DROP EXISTING SELECT * FROM " + $ByName
$cmd = New-Object System.Data.Odbc.OdbcCommand($sql,$conn)
$count = $cmd.ExecuteNonQuery()
$conn.Close()
The driver gives you complete control over the caching functionality. See the help documentation for more caching commands and usage examples. See the help documentation for steps to replicate to other databases.
Other Operations
To retrieve HCL Domino data in PowerShell, call the Fill method of the OdbcDataAdapter method. To execute data manipulation commands, initialize the OdbcCommand object and then call ExecuteNonQuery. Below are some more examples commands to HCL Domino through the .NET Framework Provider for ODBC:
Retrieve HCL Domino Data
$sql="SELECT Name, Address from ByName"
$da= New-Object System.Data.Odbc.OdbcDataAdapter($sql, $conn)
$dt= New-Object System.Data.DataTable
$da.Fill($dt)
$dt.Rows | foreach {
$dt.Columns | foreach ($col in dt{
Write-Host $1[$_]
}
}
