Review the version of the configuration parameter file.
n is a string of numbers up to 7 characters long, usually in dot format.
Version is the configuration parameter file (CPF) version number. This value is independent of the product release number. It is updated automatically during product upgrade or installation. The number refers to the syntax and structure of the parameter file, and not to the changes that you might make to the parameter values within the file.
Changing this value from the default can cause InterSystems IRIS® data platform to fail on startup. To differentiate between multiple user-edited CPFs, use Comments as described in “Introduction to the Configuration Parameter File”.
