=item $env->get_shm_key($id)

Writes the base segment ID for the shared memory region used by the
Berkeley DB environment into C<$id>. Returns 0 on success.

This option requires Berkeley DB 4.2 or better.

Use the C<-SharedMemKey> option when opening the environmet to set the
base segment ID.

=item $env->set_isalive()

Set the callback that determines if the thread of control, identified by
the pid and tid arguments, is still running.  This method should only be
used in combination with $env->failchk.

This option requires Berkeley DB 4.4 or better.

=item $env->failchk($flags)

The $env->failchk method checks for threads of control (either a true

BerkeleyDB.pod  view on Meta::CPAN

library data structures, while holding a logical database lock, or with an
unresolved transaction (that is, a transaction that was never aborted or
committed).

If $env->failchk determines a thread of control exited while holding
database read locks, it will release those locks. If $env->failchk
determines a thread of control exited with an unresolved transaction, the
transaction will be aborted.

Applications calling the $env->failchk method must have already called the
$env->set_isalive method, on the same DB environment, and must have
configured their database environment using the -ThreadCount flag. The
ThreadCount flag cannot be used on an environment that wasn't previously
initialized with it.

This option requires Berkeley DB 4.4 or better.

=item $env->stat_print

Prints statistical information.
