static int
DbEnv.set_mutexlocks(int do_lock);
	throws DbException;

Description

Toggle mutex locks. Setting do_lock to a false value causes Berkeley DB to grant all requested mutual exclusion mutexes without testing for their availability.

The DbEnv.set_mutexlocks interface affects the entire application, not a single database or database environment.

While the DbEnv.set_mutexlocks interface may be used to configure Berkeley DB at any time during the life of the application, it should normally be called before making any calls to the db_env_create or db_create methods.

This functionality should never be used for any other purpose than debugging.

The DbEnv.set_mutexlocks interface may be used to configure Berkeley DB at any time during the life of the application.

The DbEnv.set_mutexlocks method throws an exception that encapsulates a non-zero error value on failure.

Errors

EINVAL

An invalid flag value or parameter was specified.
