import com.sleepycat.db.*;public void set_re_len(int re_len) throws DbException;
For the Queue access method, specify that the records are of length re_len.
For the Recno access method, specify that the records are fixed-length, not byte-delimited, and are of length re_len.
Any records added to the database that are less than re_len bytes long are automatically padded (see Db.set_re_pad for more information).
Any attempt to insert records into the database that are greater than re_len bytes long will cause the call to fail immediately and return an error.
The Db.set_re_len interface may be used only to configure Berkeley DB before the Db.open interface is called.
The Db.set_re_len method throws an exception that encapsulates a non-zero error value on failure.
The Db.set_re_len method may fail and throw an exception encapsulating a non-zero error for the following conditions:
Called after Db.open was called.
The Db.set_re_len method may fail and throw an exception for errors specified for other Berkeley DB and C library or system methods. If a catastrophic error has occurred, the Db.set_re_len method may fail and throw a DbRunRecoveryException, in which case all subsequent Berkeley DB calls will fail in the same way.

enough smaller than the database's page size that at least one record
plus the database page's metadata information can fit on each database
page.
