int
DBENV->set_lk_max_lockers(DB_ENV *dbenv, u_int32_t max);
Description
Set the maximum number of simultaneous locking entities supported by
the Berkeley DB lock subsystem. 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_lockers interface may only be used to configure Berkeley DB before
the DBENV->open interface is called.
The DBENV->set_lk_max_lockers function returns a non-zero error value on failure and 0 on success.
The database environment's maximum number of lockers 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_lockers", one or more whitespace characters,
and the number of lockers. Because the DB_CONFIG file is read when the database
environment is opened, it will silently overrule configuration done
before that time.
