[hjs123]

Hi.
I want to collect for the ms-sql data.
but, the following error occurs.
I do not know the cause.
What's wrong ?

connectionString=jdbc:sqlserver://10.1.1.10;instanceName=STEST;databaseName=master;
username=t_test
password=test123
driverClass=com.microsoft.sqlserver.jdbc.SQLServerDriver

++++++++++++++ error log ++++++++++++++++++++++++++++++++++++++++

Verify the connectionString. AFAIK, SQL Server no longer uses instance names. Instead server instances are specified by port number (sqlserver://10.1.1.10:10100).
