Set each of the maximum number of locks, lockers and lock objects
supported by the Berkeley DB lock subsystem to max. This value is
used by DBENV->open to estimate how much space to allocate for
various lock-table data structures. For specific information on
configuring the size of the lock subsystem, see
Configuring locking: sizing the
system.
The DBENV->set_lk_max interface may only be used to configure Berkeley DB before
the DBENV->open interface is called.
The DBENV->set_lk_max function returns a non-zero error value on failure and 0 on success.
The database environment's maximum number of locks may also be set using the environment's
DB_CONFIG file. The syntax of the entry in that file is a
single line with the string "set_lk_max", one or more whitespace characters,
and the number of locks. Because the DB_CONFIG file is read when the database
environment is opened, it will silently overrule configuration done
before that time.
