The SecondaryRecnoDatabaseConfig type exposes the following members.
Fields
Name | Description | |
---|---|---|
AutoCommit |
Enclose the open call within a transaction. If the call succeeds,
the open operation will be recoverable and all subsequent database
modification operations based on this handle will be transactionally
protected. If the call fails, no database will have been created.
(Inherited from DatabaseConfig.) | |
BackingFile |
The underlying source file for the Recno access method.
| |
ByteOrder |
The byte order for integers in the stored database metadata. The
host byte order of the machine where the Berkeley DB library was
compiled is the default value.
(Inherited from DatabaseConfig.) | |
CacheSize |
The size of the shared memory buffer pool -- that is, the cache.
(Inherited from DatabaseConfig.) | |
Creation |
The policy for how to handle database creation.
| |
DoChecksum |
If true, do checksum verification of pages read into the cache from
the backing filestore.
(Inherited from DatabaseConfig.) | |
Env |
The Berkeley DB environment within which to create a database. If
null, the database will be created stand-alone; that is, it is not
part of any Berkeley DB environment.
(Inherited from DatabaseConfig.) | |
ErrorFeedback |
The mechanism for reporting error messages to the application.
(Inherited from DatabaseConfig.) | |
ErrorPrefix |
The prefix string that appears before error messages issued by
Berkeley DB.
(Inherited from DatabaseConfig.) | |
Feedback | ||
FreeThreaded |
Cause the database object to be free-threaded; that is, concurrently
usable by multiple threads in the address space.
(Inherited from DatabaseConfig.) | |
ImmutableKey |
If true, the secondary key is immutable.
(Inherited from SecondaryDatabaseConfig.) | |
NoMMap |
Do not map this database into process memory.
(Inherited from DatabaseConfig.) | |
NonDurableTxns |
If true, Berkeley DB will not write log records for this database.
(Inherited from DatabaseConfig.) | |
Populate |
If true and the secondary database is empty, walk through Primary
and create an index to it in the empty secondary. This operation is
potentially very expensive.
(Inherited from SecondaryDatabaseConfig.) | |
Priority |
The cache priority for pages referenced by the database.
(Inherited from DatabaseConfig.) | |
ReadOnly |
Open the database for reading only. Any attempt to modify items in
the database will fail, regardless of the actual permissions of any
underlying files.
(Inherited from DatabaseConfig.) | |
ReadUncommitted |
Support transactional read operations with degree 1 isolation.
(Inherited from DatabaseConfig.) | |
Renumber |
Cause the logical record numbers to be mutable, and change as
records are added to and deleted from the database.
| |
Snapshot |
If true, any BackingFile file will be read in its
entirety when Open(String, SecondaryRecnoDatabaseConfig) is called.
If false, BackingFile may be read lazily.
| |
Truncate |
Physically truncate the underlying file, discarding all previous databases it might have held.
(Inherited from DatabaseConfig.) | |
UseMVCC |
Open the database with support for multiversion concurrency control.
