The Connection to Hach WIMS screen lets you configure how the interface will connect to Hach WIMS Database Server.

This is one of the first items you configure when setting up a new interface.

• Data Source - this field specifies, in loose terms, the "Database/Datasource server name" where your Hach WIMS system is configured to store data. "Database/Datasource server name" means different things depending on whether you are running against Oracle or MS SQL:
  
• Oracle - you can type in either the Oracle TNS name or a string in the form of host:port/SID, if using the Oracle HOSTNAME adapter.
• MS SQL - this is in the form of host\sql_instance_name
  
• Database Type -select the appropriate type of your Hach WIMS database
  
• OLE DB Provider - this specifies which "database driver" the interface will use when connecting to Hach WIMS and again depends on the database type:
  
• Oracle - the default string should be fine
• MS SQL - if connecting to MS SQL 2005 or later, use the native client to connect. Specify SQLNCLI as the provider. NOTE: You will need to have the Microsoft SQL Native Client installed for this to work. If connecting to MS SQL 2000, specify SQLOLEDB as the provider.
  
• Connection Timeout in Seconds - how many seconds the program should wait when establishing a connection to the Hach WIMS database before aborting.
  
• Command Timeout in Seconds - specifies how many seconds the program should wait for a query to complete before aborting the operation.
  
  WARNING: Large values for these two settings can cause the program to not respond for a long period of time! Do NOT use 0 unless you know what you are doing - it will cause the program to wait indefinitely, and if your database server is down, the only way to cancel the operation is to forcefully quit the program.
  
• Customizations - this should be left empty unless you were told otherwise by a Hach Support Engineer or you know what you are doing.

Buttons:

Test to see if the connection settings are valid and the interface is able to connect to Hach WIMS client. This will NOT Apply or Save the settings.

The other buttons are explained in Using Common Buttons.
