When an application connects to a database, it uses a set of connection parameters to define the connection. Connection parameters include information such as the server name, the database name, and a user ID.
A keyword-value pair, of the form parameter=value, specifies each connection parameter. For example, you specify the password connection parameter for the default password as follows:
Password=sql
Connection parameters are assembled into connection strings. In a connection string, a semicolon separates each connection parameter, as follows:
ServerName=host_iqdemo;DatabaseName=iqdemo
Several connection parameters affect how a server is started. It is recommended that you use the following connection parameters instead of providing the corresponding server options within the StartLine (START) connection parameter:
EngineName (ENG)
DatabaseFile (DBF)
DatabaseName (DBN)
This chapter has many examples of connection strings, represented in the following form:
parameter1=value1 parameter2=value2 ...
This is equivalent to the following connection string:
parameter1=value1;parameter2=value2
You must enter a connection string on a single line, with the parameter settings separated by semicolons.
