void XmlManager::setDefaultContainerFlags(u_int32_t flags)

u_int32_t XmlManager::getDefaultContainerFlags()

Description: XmlManager::setDefaultContainerFlags

Sets the default flags used for containers opened and created by this XmlManager object. If a form of XmlManager::createContainer or XmlManager::openContainer is used that takes a flags argument, the settings provided using this method are ignored.

Parameters

flags

The flags to use for this container creation. The flags parameter must be set to 0 or by bitwise inclusively OR'ing together one or more of the following values:

DB_CREATE

If the container does not currently exist, create it.

DB_READ_UNCOMMITTED

This operation will support degree 1 isolation; that is, read operations may return data that has been modified by other transactions but which has not yet been committed. Silently ignored if the DB_READ_UNCOMMITTED flag was not specified when the underlying container was opened.

DB_EXCL

Return an error if the container already exists. The DB_EXCL flag is only meaningful when specified with the DB_CREATE flag.

DB_MULTIVERSION

Open the database with support for multiversion concurrency control. This will cause updates to the container to follow a copy-on-write protocol, which is required to support snapshot isolation. The DB_MULTIVERSION flag requires that the container be transactionally protected during its open.

DB_NOMMAP

Do not map this container into process memory (see the DbEnv::set_mp_mmapsize method for further information).

DB_RDONLY

Open the container for reading only. Any attempt to modify items in the container will fail, regardless of the actual permissions of any underlying files.

DB_THREAD

Cause the container handle to be free-threaded; that is, concurrently usable by multiple threads in the address space.

DB_XA_CREATE

Instead of creating a standalone database, create a database intended to be accessed via applications running under an X/Open conformant Transaction Manager. The database will be opened in the environment specified by the OPENINFO parameter of the GROUPS section of the ubbconfig file. See the XA Introduction section in the Berkeley DB Reference Guide for more information.

DBXML_CHKSUM

Do checksum verification of pages read into the cache from the backing filestore. Berkeley DB XML uses the SHA1 Secure Hash Algorithm if encryption is configured and a general hash algorithm if it is not.

DBXML_ENCRYPT

Encrypt the database using the cryptographic password specified to DbEnv::set_encrypt.

DB_TXN_NOT_DURABLE

If set, Berkeley DB XML will not write log records for this database. This means that updates of this database exhibit the ACI (atomicity, consistency, and isolation) properties, but not D (durability); that is, database integrity will be maintained, but if the application or system fails, integrity will not persist. The database file must be verified and/or restored from backup after a failure.

DBXML_INDEX_NODES

Relevant for node storage containers only. Causes the indexer to create index targets that reference nodes rather than documents. This allows XmlContainer::lookupIndex to return individual nodes rather than whole documents.

DBXML_TRANSACTIONAL

Cause the container to support transactions. If this flag is set, an XmlTransaction object may be used with any method that supports transactional protection. Also, if this flag is used, and if an XmlTransaction object is not provided to a method that modifies an XmlContainer or XmlDocument object, then auto commit is automatically used for the operation.

DBXML_ALLOW_VALIDATION

When loading documents into the container, validate the XML if it refers to a DTD or XML Schema.
