When trying to test a connection to a Sybase instance using the sybase probe encounter the following error:
Profile test connection/check_dbalive, is not connected to <instance_name>, err: The parameter %1! cannot be NULL.
Identify what the server name is defined as in the sql.ini file. Case sensitivity is important. Use the same name with case sensitivity when creating the connection in the Sybase probe.
In case of enhanced encryption is being used, currently, on windows platform sybase probe do not support this enhanced encryption functionality. Requirement for enhanced encryption resulted in the same error message.
