Sybase IQ requires the DBF parameter and database file name in order to connect to a database under certain circumstances.
This situation occurs when you use Interactive SQL and you have restored that database from backup while connected to utility_db.
CONNECT USING 'uid=DBA;pwd=sql;dbf=node1/users/fiona/mydb.db; links=tcpip{host=serv1;port=1234};eng=serv1_iqdemo'
CONNECT DATABASE mydb USER DBA IDENTIFIED BY SQL
The preceding command now returns a specified database not found error.
START DATABASE mydbUse this method when connecting via Interactive SQL.
