Introduction : Using parameter files : Parameter file format

Parameter file format

The following file is a sample parameter file:
-db /usr/disk0/newyork # new york central db

-B 200 # database buffers
-H nysystem -S nyserver # host, service
-L 10000 # lock table entries

# All other parameters receive their default values.
The format of the parameter file is the same for all operating systems. Follow these rules when creating a parameter file:
*Place a parameter and its argument on the same line.
*Use a maximum of 40 tokens per line in a parameter file.
*Specify parameters with the UNIX syntax.
*Use a pound sign (#) to begin a comment. OpenEdge ignores the rest of the line.
*Enclose a value in single (') or double (") quotes. Any white space inside the quotes is treated as part of the token.
*Any parameter not named in a parameter file receives a default value. To remind yourself of the default values, consider specifying all parameters and their values in the parameter file and adding the comment "# default" to those values that do not change.
*Use a tilde (~) to suppress the special meaning of the single (') or double (") quotes or tilde (~). A tilde also prefixes the control characters that OpenEdge can recognize in a parameter file, as listed in the following table.
Octal code
The character having octal code nnn
BS character
HT (horizontal tab) character
LF (line feed) character
VT (carriage return) character
FF (form feed) character
ESC character.
On UNIX, use the backslash (\) in place of a tilde.
