public void set_lk_max_objects(int max)
	throws DbException;

Description

Set the maximum number of simultaneously locked objects 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_objects interface may only be used to configure Berkeley DB before the DbEnv.open interface is called.

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

The database environment's maximum number of objects 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_objects", one or more whitespace characters, and the number of objects. Because the DB_CONFIG file is read when the database environment is opened, it will silently overrule configuration done before that time.

Errors

EINVAL

An invalid flag value or parameter was specified.

Called after DbEnv.open was called.
