The RecnoDatabase type exposes the following members.

# Properties

| Name | Description
--- | --- | ---
| AppendCallback | A function to call after the record number has been selected but before the data has been stored into the database.
| AutoCommit | If true, all database modification operations based on this object are transactionally protected. (Inherited from BaseDatabase.)
| CacheSize | The size of the shared memory buffer pool (the cache). (Inherited from BaseDatabase.)
| Creation | The CreatePolicy with which this database was opened. (Inherited from BaseDatabase.)
| DatabaseName | The name of this database, if it has one. (Inherited from BaseDatabase.)
| DoChecksum | If true, do checksum verification of pages read into the cache from the backing filestore. (Inherited from BaseDatabase.)
| EncryptAlgorithm | The algorithm used by the Berkeley DB library to perform encryption and decryption. (Inherited from BaseDatabase.)
| Encrypted | If true, encrypt all data stored in the database. (Inherited from BaseDatabase.)
| Endianness | The database byte order. (Inherited from BaseDatabase.)
| ErrorFeedback | The mechanism for reporting detailed error messages to the application. (Inherited from BaseDatabase.)
| ErrorPrefix | The prefix string that appears before error messages issued by Berkeley DB. (Inherited from BaseDatabase.)
| Feedback | Monitor progress within long running operations. (Inherited from BaseDatabase.)
| FileName | The filename of this database, if it has one. (Inherited from BaseDatabase.)
| FreeThreaded | If true, the object is free-threaded; concurrently usable by multiple threads in the address space. (Inherited from BaseDatabase.)
| HasMultiple | If true, the object references a physical file supporting multiple databases. (Inherited from BaseDatabase.)
| InHostOrder | If true, the underlying database files were created on an architecture of the same byte order as the current one. This information may be used to determine whether application data needs to be adjusted for this architecture or not. (Inherited from BaseDatabase.)
| messageFeedback | The mechanism for reporting detailed statistic messages to the application. (Inherited from BaseDatabase.)
| MessagePrefix | The prefix string that appears before informational messages issued by Berkeley DB. (Inherited from BaseDatabase.)
| Msgfile | The message file. (Inherited from BaseDatabase.)
| NoMMap | If true, this database is not mapped into process memory. See MMapSize for further information. (Inherited from BaseDatabase.)
| NonDurableTxns | If true, Berkeley DB does not write log records for this database. (Inherited from BaseDatabase.)
| NoWaitDbExclusiveLock | If true, configure the database handle to obtain a write lock on the entire database. When the database is opened it immediately throws LockNotGrantedException if it cannot obtain the exclusive lock immediately. If False, configure the database handle to obtain a write lock on the entire database. When the database is opened, it blocks until it can obtain the exclusive lock. If null, do not configure the database handle to obtain a write lock on the entire database. (Inherited from BaseDatabase.)
| Pagesize | The database's current page size. (Inherited from BaseDatabase.)
| Priority | The cache priority for pages referenced by this object. (Inherited from BaseDatabase.)
| ReadOnly | If true, this database has been opened for read only. Any attempt to modify items in the database will fail, regardless of the actual permissions of any underlying files. (Inherited from BaseDatabase.)
| ReadUncommitted | If true, this database supports transactional read operations with degree 1 isolation. Read operations on the database may request the return of modified but not yet committed data. (Inherited from BaseDatabase.)
| RecordDelimiter | The delimiting byte used to mark the end of a record in SourceFile.
| RecordLength | If using fixed-length, not byte-delimited records, the length of the records.
| RecordPad | The padding character for short, fixed-length records.
| Renumber | If true, the logical record numbers are mutable, and change as records are added to and deleted from the database.
| Snapshot | If true, any SourceFile file is read in its entirety when Open(String, RecnoDatabaseConfig) is called. If false, SourceFile may be read lazily.
| SourceFile | The underlying source file for the Recno access method.
| Transactional | If true, this database has been opened in a transactional mode. (Inherited from BaseDatabase.)
| Truncated | If true, the underlying file was physically truncated upon open, discarding all previous databases it might have held. (Inherited from BaseDatabase.)
| Type | The type of the underlying access method (and file format). This value may be used to determine the type of the database after an Open(String, DatabaseConfig). (Inherited from BaseDatabase.)
| UseMVCC | If true, the database was opened with support for multiversion concurrency control. (Inherited from BaseDatabase.)
