NAME
     ttdbck - display, check, or repair	ToolTalk databases

SYNOPSIS
     ttdbck [ selection	opts ] [ diagnosis opts	] [  display opts
     ] [ repair	opts ]
	  [ data-base-directory	]...

DESCRIPTION
     ttdbck is the ToolTalk database maintenance tool.	It allows
     direct inspection of ToolTalk spec	data, detection	of incon-
     sistencies, and repair of problems.

OPTIONS
     data-base-directory
	  Names	the directory or directories containing	the Tool-
	  Talk database	to be inspected	or repaired. If	no direc-
	  tories are named, the	current	directory is assumed.  If
	  a  directory	path does not end in ``TT_DB'',	``TT_DB''
	  is appended.

	  The user running the command must have read  access  to
	  the  files  in  the  directory  to inspect the data and
	  write	access to repair the data.  Since ToolTalk  data-
	  bases	 are typically accessible only to root,	this com-
	  mand is normally run as root.

  Selection options
     The selection options determine which specs in the	 database
     are  displayed  or	 modified.   If	 no selection options are
     given, all	specs in the database are displayed.  To  prevent
     massive  accidental changes to ToolTalk databases,	no repair
     options except -I are allowed unless a  selection	or  diag-
     nosis option is given.

     -f	filename
	  Restricts the	set of specs to	be inspected or	 modified
	  to  those which describe objects in the named	file. The
	  file name can	contain	shell-style wildcards which  must
	  be escaped to	prevent	the shell from expanding them.

     -k	objidkey
	  An object id key, specifying a particular  spec  to  be
	  displayed  or	 modified.   The  object  id  key  can be
	  obtained from	a  previous  invocation	 of  ttdbck;  one
	  might	 display  a  set of specs, determine the one that
	  needs	repair,	and specify its	key here.

     -t	type
	  Restricts the	set of specs to	be inspected or	 modified
	  to  those  with  otype  type.	The type name can contain
	  shell-style wildcards	which must be escaped to  prevent

	  the shell from expanding them.

  Diagnosis options
     These options check for and report	on inconsistencies in the
     selected  specs.	Only  specs  selected  by  the	selection
     options are checked.  If a	diagnosis option  is  given,  any
     display or	repair option is applied only to specs which fail
     the diagnostic check.

     -b	  Check	for badly formed specs:	those which have no  file
	  or  type  or	those which have types not defined in the
	  type database.

     -x	  Check	for specs which	refer to  files	 that  no  longer
	  exist.

  Display options
     These options determine  which  data  is  printed	for  each
     selected spec.

     -i	  Display the object id	(including the object id key.)

     -m	  Display the mandatory	data that must	appear	in  every
	  spec:	the otype of the object	described by the spec and
	  the file in which the	spec is	stored.

     -p	  Display all the properties and values	for each selected
	  spec.

     -a	  Display all data (equivalent to specifying -imp)

  Repair options
     -I	  Invoke the NetISAM isrepair()	function  for  all  files
	  accessed.   This  action  is	applied	 before	any other
	  inspection or	repair action.	 This  option  should  be
	  used when normal operations return EBADFILE (error code
	  105).

     -F	filename
	  Change the file name for the selected	specs to the sup-
	  plied	file name.

     -T	otypeid
	  Change the type of the  selected  specs  to  the  given
	  otype.

     -Z	  Remove the selected specs entirely.

EXAMPLES

     In	the /home/TT_DB	directory, finds all badly  formed  specs
     and  specs	that refer to non-existent files and prints their
     ids.

	  ttdbck -f /home/sample/data -F /home/sample/data1 /home

     In	the /home/TT_DB	directory, finds all specs that	refer  to
     objects  in file /home/sample/data	and changes them to refer
     to	/home/sample/data1.

	  ttdbck -t Sample_Otype_Name -Z /export/TT_DB

     In	the /export/TT_DB directory, finds all specs  that  refer
     to	objects	of type	Sample_Otype_Name and deletes the specs.

FILES
     /path/TT_DB	 ToolTalk database

NOTES
     The ttdbck	command	should be run on the same  machine  where
     the  TT_DB	 files	being  inspected  and repaired physically
     exist.  That is, don't try	to access  the	TT_DB  files  via
     NFS.
