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
          ttdbck -bxi /home


     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.
