.D Binary user boot fileNational Language Support Utilities 9-7 NLS Configuration UtilityOverviewAt installation, all available NLS objects are stored and referenced in thesystem boot file.This file is used to load the available NLS dam.The NLS Configuration Utility allows you to configure your boot files suchthat only the NLS objects that you require will be loaded.It does this bycreating a user boot file, which contains a subset of the system boot file.Dataloading by the kernel will then be performed according to the contents of thisuser boot file.The NLS Configuration Utility allows you to configure a user boot file, eitherby selecting NLS objects from the installed system boot file which will then beincluded in a new user boot file, or by reading entries from an existing userboot file and possibly removing one or more of them and saving theremaining entries into a new user boot file.Note that you will not be allowedto actually edit an existing boot file as it may be in use by either the RDBMSor some other Oracle tool (that is, saving of boot file entries is never done toan existing one).You may also use the NLS Data Installation Utility to check the integrity of anexisting user boot file.This is necessary since the contents of existing NLSobjects may change over time, and the installation of a new system boot filemay cause user boot files to become out of date.Thus, a comparison functionwill notify you when it finds that the file is out of date and will allow you tocreate a new user boot file.9-8 Oracle8 Server Utilities SyntaxThe NLS Configuration Utility is invoked from the command line with thefollowing syntax:LXBCNF [ORANLS=pathname] [userbootdir=pathname][DESTDIR=pathname] [HELP=[yes |no]]where:ORANLS= Specifies where to find the system boot file.If notpathname specified, the value in the environment variableORA_NLS (or the equivalent on your operating system)will be used.If both are specified, the command nameparameter will override the environment variable.Ifneither is specified, the NLS Configuration Utility willexit with an error message.SYSDIR= Specifies where to find an existing user boot file.If notpathname specified, the directory specified in the ORANLSparameter will be used.DESTDIR= Specifies where to put the new user boot file.If notpathname specified, the directory specified in the ORANLSparameter will be used.HELP=[yes|no] If yes , a help message describing the syntax isprinted.MenusWhen the NLS Configuration Utility is started you are presented with thefollowing top-level menu:" File Menu" Edit Menu" Action Menu" Windows Menu" HelpNational Language Support Utilities 9-9 File MenuThe file menu contains choices pertaining to file operations.Options are:Table 9-1: File Menu OptionsMenu Item Options DescriptionSystem Boot File Open This will open the current system boot file.Note that theOpen menu item will be grayed out as soon as asystem Boot File has been successfully read.Also notethat you cannot perform any other functions until youhave opened a system boot file.User Boot File New Open a new user boot file.Read Read the contents of an existing user boot file.Save Save changes to the new user boot file.Revert Undo the changes to the currently open user boot filemade since the last Save.
