NAME

       ypmake - rebuild Network Information Service (NIS) database using the make command

SYNOPSIS

       cd /var/yp make [options] [map]

OPTIONS

       The  options  argument can be used to override the default values of three special variables used by make: Instructs make to use the source
       files in the specified directory. The default is /var/yp/src.  Instructs make to construct a domain other than the master's default domain.
       The  DOM  variable in the /var/yp/Makefile file must be set to the domain name before running make. If you run ypsetup, the DOM variable is
       set when you specify a domain name.  Specifies the database routines used to store NIS maps.  The choices are: btree  --  Recommended  when
       creating  and  maintaining  very  large maps.  dbm/ndbm -- For backward compatibility.  This is the default.  hash -- A potentially quicker
       method for managing small maps.	When non-null inhibits updating of the new database files using the yppush(8) function. The default is the
       null string.

       To  override  the default values of these special variables, an options argument format of special_variable = value is used.  See the EXAM-
       PLES section for an example.

       The map argument supplied on the command line instructs make to update only the specified map. The specified  maps  are	those  located	at
       /var/yp/{domain}, where {domain} is the NIS domain name. Some typical entries for the map argument are passwd, hosts, and networks.  Typing
       make passwd creates and updates the NIS password database, if it is out of date. The make command distributes the updated password database
       to  the	slave  servers	using  yppush(8).  Therefore,  typing  make  host or make networks creates and updates the host and network files,
       /var/yp/src/hosts and /var/yp/src/networks, respectively, on the master and slave servers.

       See ypfiles(4) and ypserv(8) for an overview of NIS.

DESCRIPTION

       The make command uses the /var/yp/Makefile file to build an NIS database. With no arguments, make creates databases for any NIS	maps  that
       are out-of-date, and then executes yppush(8) to notify slave servers that there has been a change.

									  Note

       Execute	the make command only at an NIS master server machine.	If it is executed from either a slave server or an NIS client machine, the
       created changes will only be overwritten when the next NIS master server machine update, using ypxfr(8), is performed.

RESTRICTIONS

       You must use the same database format for each map in a domain. In addition, a server serving multiple NIS domains must use the same  data-
       base format for all domains.

       Although  a  Tru64  UNIX  NIS server that takes advantage of btree files will be able to store very large maps, NIS slave servers that lack
       this feature might have a much smaller limit on the number of map entries they can handle.  It may not be possible to distribute very large
       maps  from  a Tru64 UNIX NIS master server to a slave server that lacks support for very large maps.  NIS clients are not affected by these
       enhancements.

EXAMPLES

       This example causes make to create a password NIS map for the domain NewDomain instead of for the default domain: make DOM=NewDomain passwd
