The collector PDF's don't currently address named instances in the jdbc connection example.
Your database needs to know what instance you are connecting to, without it your connections will fail.
Below are examples of MS SQL connection strings based on MS SQL server environment layout.
JDBC instance string method #1
MSSQL 2000:
jdbc:microsoft:sqlserver://<hostname>;instanceName=<named_instance>;DatabaseName=DB_name
MSSQL 2005:
jdbc:sqlserver://<hostname>;instanceName=<named_instance>;DatabaseName=DB_name
JDBC instance string method #2
MSSQL 2000:
jdbc:microsoft:sqlserver://<hostname>\<named_instance>:1433;DatabaseName=DB_name
MSSQL 2005:
jdbc:sqlserver://<hostname>\<named_instance>:1433;DatabaseName=DB_name
JDBC clustered environement string method
MSSQL 2005:
jdbc:sqlserver://<named_instance>:1433;DatabaseName=sepm
Note: For the clustered environment string, you do not need <hostname> in the string, just the instance name.
If the examples below do not work, please contact your MS SQL database administrator for the exact string needed in that case.
