HPL configuration parameter file conventions
Each parameter in the plconfig.std file in the etc directory in $INFORMIXDIR is on a separate line. The file can also contain blank lines and comment lines that start with a # symbol.
The syntax of a parameter line is as follows:
PARAMETER_NAME parameter_value # optional commentParameters and their values are case-sensitive. The parameter names are always all uppercase letters. If the parameter-value entry is described with uppercase letters, you must use uppercase. You must put white space (tabs or spaces or both) between the parameter name, parameter value, and optional comment. Do not use any tabs or spaces within a parameter value.
