db5.3verify -  Verifies the structure databases


db5.3verify [-NoqV] [-h home] [-P password] file ...


The  db5.3verify  utility verifies the structure of one or more files and the databases they
contain.

  -h
directory is used.
  -o
If  the  file being verified contains databases with non-default comparison or hashing
configurations, calling the db5.3verify utility without the -o flag will usually  re‐
turn  failure.  The -o flag causes db5.3verify to ignore database sort or hash order‐
ing and allows db5.3verify to be used on these files.  To fully verify  these  files,
verify them explicitly using the DB->verify method, after configuring the correct com‐
parison or hashing functions.
  -N
tially  fatal errors in Berkeley DB, will be ignored as well.  This option is intended
only for debugging errors, and should not be used under any other circumstances.
  -P
strings  as  soon as possible, be aware there may be a window of vulnerability on sys‐
tems where unprivileged users can see command-line arguments or  where  utilities  are
not able to overwrite the memory containing the command-line arguments.
  -q
  -V
The  db5.3verify utility does not perform any locking, even in Berkeley DB environments that
  are configured with a locking subsystem.  As such, it should only be used on files  that  are
  not being modified by another thread of control.
The  db5.3verify utility may be used with a Berkeley DB environment (as described for the -h
option, the environment variable DBHOME, or because the utility was run in a directory  con‐
taining  a  Berkeley  DB environment).  In order to avoid environment corruption when using a
Berkeley DB environment, db5.3verify should always be given the chance to  detach  from  the
environment  and exit gracefully.  To cause db5.3verify to release all environment resources
and exit cleanly, send it an interrupt signal (SIGINT).

The db5.3verify utility exits 0 on success, and >0 if an error occurs.


DBHOME
If the -h option is not specified and the environment variable DBHOME is set,  it  is
used as the path of the database home, as described in DBENV->open.
