TTSERVER(1)			 Tokyo Tyrant			   TTSERVER(1)

NAME
       ttserver	- the server of	Tokyo Tyrant

DESCRIPTION
       The  command  `ttserver'	 runs the server managing a database instance.
       Because the database is treated by the abstract API of  Tokyo  Cabinet,
       you  can	choose the scheme on start-up of the server.  Supported	schema
       are on-memory hash database, on-memory tree  database,  hash  database,
       and  B+	tree  database.	 This command is used in the following format.
       `dbname'	specifies the database name.  If it is omitted,	on-memory hash
       database	is specified.

	      ttserver	[-host	name]  [-port  num]  [-thnum  num] [-tout num]
	      [-dmn] [-pid path] [-kl]	[-log  path]  [-ld|-le]	 [-ulog	 path]
	      [-ulim  num]  [-uas] [-sid num] [-mhost name] [-mport num] [-rts
	      path] [-rcc] [-skel name]	[-mul num] [-ext  path]	 [-extpc  name
	      period] [-mask expr] [-unmask expr] [dbname]

       Options feature the following.

	      -host name : specify the host name or the	address	of the server.
	      By default, every	network	address	is bound.
	      -port num	: specify the port number.  By default,	it is 1978.
	      -thnum num : specify the number of worker	threads.  By  default,
	      it is 8.
	      -tout  num : specify the timeout of each session in seconds.  By
	      default, no timeout is specified.
	      -dmn : work as a daemon process.
	      -pid path	: output the process ID	into the file.
	      -kl : kill the existing process if the process ID	 file  is  de-
	      tected.
	      -log path	: output log messages into the file.
	      -ld : log	debug messages also.
	      -le : log	error messages only.
	      -ulog path : specify the update log directory.
	      -ulim num	: specify the limit size of each update	log file.
	      -uas : use asynchronous I/O for the update log.
	      -sid num : specify the server ID.
	      -mhost  name  :  specify the host	name of	the replication	master
	      server.
	      -mport num : specify the port number of the  replication	master
	      server.
	      -rts path	: specify the replication time stamp file.
	      -rcc : check consistency of replication.
	      -skel name : specify the name of the skeleton database library.
	      -mul  num	: specify the division number of the multiple database
	      mechanism.
	      -ext path	: specify the script language extension	file.
	      -extpc name period : specify the function	name and  the  calling
	      period of	a periodic command.
	      -mask expr : specify the names of	forbidden commands.
	      -unmask expr : specify the names of allowed commands.

       To  terminate  the  server  normally,  send  SIGINT  or	SIGTERM	to the
       process.	 It is okay to press Ctrl-C on the controlling	terminal.   To
       restart	the server, send SIGHUP	to the process.	 If the	port number is
       not more	than 0,	UNIX domain socket is used and the path	of the	socket
       file  is	 specified  by	the host parameter.  This command returns 0 on
       success,	another	on failure.

       The naming convention of	the database is	specified by the abstract  API
       of  Tokyo Cabinet.  If the name is "*", the database will be an on-mem-
       ory hash	database.  If it is "+", the database  will  be	 an  on-memory
       tree  database.	 If  its suffix	is ".tch", the database	will be	a hash
       database.  If its suffix	is ".tcb", the database	 will  be  a  B+  tree
       database.  If its suffix	is ".tcf", the database	will be	a fixed-length
       database.  If its suffix	is ".tct", the database	will be	a table	 data-
       base.  Otherwise, this function fails.  Tuning parameters can trail the
       name, separated by "#".	Each parameter is composed of the name and the
       value,  separated  by  "=".   On-memory	hash database supports "bnum",
       "capnum", and "capsiz".	On-memory tree database	supports "capnum"  and
       "capsiz".   Hash	 database  supports  "mode",  "bnum",  "apow", "fpow",
       "opts", "rcnum",	 and  "xmsiz".	 B+  tree  database  supports  "mode",
       "lmemb",	"nmemb", "bnum", "apow", "fpow", "opts", "lcnum", "ncnum", and
       "xmsiz".	 Fixed-length database supports	"mode",	"width", and "limsiz".
       Table  database	supports  "mode", "bnum", "apow", "fpow", "opts", "rc-
       num", "lcnum", "ncnum", "xmsiz",	and "idx".  The	tuning parameter "cap-
       num"  specifies the capacity number of records.	"capsiz" specifies the
       capacity	size of	using memory.  Records spilled the  capacity  are  re-
       moved  by  the storing order.  "mode" can contain "w" of	writer,	"r" of
       reader, "c" of creating,	"t" of truncating, "e" of no locking, and  "f"
       of  non-blocking	 lock.	 The default mode is relevant to "wc".	"opts"
       can contains "l"	of large option, "d" of	Deflate	option,	"b"  of	 BZIP2
       option,	and "t"	of TCBS	option.	 "idx" specifies the column name of an
       index  and  its	type   separated   by	":".	For   example,	 "cas-
       ket.tch#bnum=1000000#opts=ld"  means that the name of the database file
       is "casket.tch",	and the	bucket number is 1000000, and the options  are
       large and Deflate.

       The  command  mask  expression  is a list of command names separated by
       ",".  For example, "out,vanish,copy" means a set	 of  "out",  "vanish",
       and "copy".  Commands of	the memcached compatible protocol and the HTTP
       compatible protocol are also forbidden or allowed, related by the  mask
       of each original	command.  Moreover, there are meta expressions.	 "all"
       means all commands.  "allorg" means all commands	of the original	binary
       protocol.   "allmc" means all commands of the memcached compatible pro-
       tocol.  "allhttp" means all commands of the HTTP	 compatible  protocol.
       "allread"  is  the  abbreviation	 of `get', `mget', `vsiz', `iterinit',
       `iternext', `fwmkeys', `rnum', `size', and `stat'.  "allwrite"  is  the
       abbreviation  of	 `put',	`putkeep', `putcat', `putshl', `putnr',	`out',
       `addint', `adddouble', `vanish',	and `misc'.  "allmanage" is the	abbre-
       viation of `sync', `optimize', `copy', `restore', and `setmst'.	"repl"
       means replication as master.  "slave" means replication as slave.
