SYMPTOM:
When connecting to a Sybase IQ database using Strategy DB Query tool 10.x, the error "Database server not found" may be encountered as shown below:

Additionally, it is confirmed that the 'DatabaseName' and 'CommLinks' parameters in the ODBC.ini file are correctly set.
CAUSE:
One possible cause is that the 'EngineName' parameter is set incorrectly in the odbc.ini file.
ACTION:
Confirm and correct the EngineName parameter in the odbc.ini file to resolve this error. 'EngineName' should be the name of the database server to connect to.
