未找到isix异常unixODBC数据源名称

I am trying to connect my php application with SQL server in my Linux box. I installed unixODBC successfully and made required changes in odbc.ini and odbcinst.ini file.

When I run command.<br><b>sqlcmd -S DSN -U USERNAME -P Password</b>

I am able to connect to sql server, but when I tried to connect with same DSN using isql (isql -v DSN USERNAME PASSWORD)<br> I am gating Data source name not found exception.
