ABSTRACT:
A configuration parameter value access system used in connection with a computer system performs an access operation in connection with a configuration parameter in response to a configuration parameter access request from an applications program. Each configuration parameter access request includes a parameter class identifier, a filename and a parameter identifier. The configuration parameter value access system includes a plurality of configuration file path class lists, each of which has at least one entry, each entry defining a storage subsystem path in the computer system's storage subsystem. A file identifier generator tests successive entries of the configuration file path class list identified by the parameter class identifier to determine whether the storage subsystem contains a file which has the filename provided in the configuration parameter access request along a path defined by an entry. If so, a configuration parameter access module performs an access operation to retrieve or update the configuration parameter identified by the parameter identifier provided in the configuration parameter access request in the file identified by the file identifier generator. If the access operation is a retrieval operation, to retrieve the value of the configuration parameter, the configuration parameter value access system will retrieve the value of the parameter, if any, in the file identified by the file identifier generator. If the access operation is an update operation, to update the value of the configuration parameter, the configuration parameter value access system will update the value of the parameter in the file identified by the file identifier generator, or create the file if no file currently exists.
