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 inconsistencies, and
       repair of problems.

OPTIONS
       data-base-directory
              Names the directory or directories containing the ToolTalk data-
              base  to  be inspected or repaired. If no directories 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  databases are typically accessible
              only to root, this command is normally run as root.

   Selection options
       The selection options determine which specs in the  database  are  dis-
       played  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 diagnosis 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 con-
              tain 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, deter-
              mine 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 wild-
              cards 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 supplied 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.
