    import com.sleepycat.db.*;

    public void set_lk_max(int lk_max)
    	throws DbException;

# Description

Set the maximum number of locks to be held or requested in the table. This value is used by DbEnv.open to estimate how much space to allocate for various lock-table data structures. If no value is specified, a default value is used.

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 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. Configuration in the DB_CONFIG file silently overrules configuration done using the DbEnv.set_lk_max method.

# Errors

EINVAL
  An invalid flag value or parameter was specified.

  Called after DbEnv.open was called.
