	throws DbException;

Description

The DbEnv.set_lk_max method interface has been deprecated in favor of the DbEnv.set_lk_max_locks, DbEnv.set_lk_max_lockers, and DbEnv.set_lk_max_objects methods. Please update your applications.

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

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.

Errors
