NAME
     ttdbserverd, rpc.ttdbserverd - RPC-based  ToolTalk	 database
     server

SYNOPSIS
     rpc.ttdbserverd [-G] [-m DTMOUNTPOINT_value] [-n] [-v] [-?]

DESCRIPTION
     rpc.ttdbserverd  manages	ToolTalk   objects   created   by
     tt_spec_create(3),	 and  handles  certain queries related to
     the netfiles returned by tt_file_netfile(3).   One	 instance
     of	 rpc.ttdbserverd (normally started by inetd) runs on each
     host that has a local  filesystem.	  rpc.ttdbserverd  serves
     four purposes:

     1.	Mapping	a spec to its associated file and a file  to  its
	associated specs.

     2.	Mapping	a spec to its properties.

     3.	Mapping	a file to a list of sessions with clients  having
	patterns registered in the scope of that file.

     4.	Answering netfile  queries;  see  tt_file_netfile(3)  and
	tt_host_file_netfile(3).

     For each filesystem  that	rpc.ttdbserverd	 needs	to  store
     information  about,  it  creates a	directory called TT_DB at
     the mountpoint of that file system.  In  that  directory  it
     creates  the  databases  it  needs	 to  store its tables and
     indices.	If  the	  partition   is   not	 writable,   then
     rpc.ttdbserverd can be told, via partition_map(4),	to create
     the   databases   in   another    local	partition.     If
     rpc.ttdbserverd  is  not  installed  on  a	 particular  file
     server, ToolTalk can be told, via hostname_map(4),	to manage
     that file server's	partitions using the rpc.ttdbserverd on	a
     different host.

OPTIONS
     -G	  Perform garbage collection.  This cleans up  the  TT_DB
	  directories and the associated internal database files.

     -m	DTMOUNTPOINT_value
	  Sets	the   DTMOUNTPOINT   environment   variable   for
	  rpc.ttdbserverd.   If	 there	is already an environment
	  variable called DTMOUNTPOINT,	-m will	override it.

     -n	  Turn off permission checking.	 Normally the  protection
	  of  the file passed to tt_spec_create(3) determines who
	  may read and write that  spec.   This	 option	 disables
	  this	checking  and allows anyone to read and	write any
	  spec.	 This option should be used with caution.

     -v	  Print	out the	version	number.

     -?	  Prints out the command usage information.

ENVIRONMENT
     DTMOUNTPOINT
	  If set, the value of this environment	variable will  be
	  used	in  place  of  "/net" in pathnames constructed to
	  answer tt_host_netfile_file(3) queries.  This	 environ-
	  ment	variable can also be set by using the -m flag for
	  rpc.ttdbserverd.

     TT_PARTITION_MAP
	  If $TT_PARTITION_MAP is set, it is  used  in	place  of
	  /etc/tt/partition_map.  See partition_map(4).

FILES
     TT_DB/*		 spec and session database files are kept
			 in  the  TT_DB	directory under	each disk
			 partition mount point.
     tt/hostname_map	 Host	  redirection	   map.	      See
			 hostname_map(4).
     /etc/tt/partition_map
			 Partition    redirection    map.     See
			 partition_map(4).
