This is the command db_verify that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
db5.3_verify - Verifies the structure databases
db5.3_verify [-NoqV] [-h home] [-P password] file ...
The db5.3_verify utility verifies the structure of one or more files and the databases
-h Specify a home directory for the database environment; by default, the current
working directory is used.
-o Skip the database checks for btree and duplicate sort order and for hashing.
If the file being verified contains databases with non-default comparison or
hashing configurations, calling the db5.3_verify utility without the -o flag will
usually return failure. The -o flag causes db5.3_verify to ignore database sort or
hash ordering and allows db5.3_verify to be used on these files. To fully verify
these files, verify them explicitly using the DB->verify method, after configuring
the correct comparison or hashing functions.
-N Do not acquire shared region mutexes while running. Other problems, such as
potentially 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
-P Specify an environment password. Although Berkeley DB utilities overwrite password
strings as soon as possible, be aware there may be a window of vulnerability on
systems where unprivileged users can see command-line arguments or where utilities
are not able to overwrite the memory containing the command-line arguments.
-q Suppress the printing of any error descriptions, simply exit success or failure.
-V Write the library version number to the standard output, and exit.
The db5.3_verify 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 db5.3_verify utility may be used with a Berkeley DB environment (as described for the
-h option, the environment variable DB_HOME, or because the utility was run in a directory
containing a Berkeley DB environment). In order to avoid environment corruption when
using a Berkeley DB environment, db5.3_verify should always be given the chance to detach
from the environment and exit gracefully. To cause db5.3_verify to release all
environment resources and exit cleanly, send it an interrupt signal (SIGINT).
The db5.3_verify utility exits 0 on success, and >0 if an error occurs.
If the -h option is not specified and the environment variable DB_HOME is set, it
is used as the path of the database home, as described in DB_ENV->open.
