- The jcdAlias attribute is a shortcut name for the defined connection
- descriptor. OJB use jcdAlias as key for the defined connections.
-
- The default-connection attribute used to define if this connection
- should used as default connection with OJB. You could define only
- one connection as default connection. It is also possible to set
- the default connection at runtime using
- PersistenceBrokerFactory#setDefaultKey(...) method.
- If set 'true' you could use on PB-api a shortcut-method of the
- PersistenceBrokerFactory to lookup PersistenceBroker instances.
-
- The platform attribute is used to define the specific RDBMS
- Platform. This attribute corresponds to a
- org.apache.ojb.broker.platforms.PlatformXXXImpl class.
-
- The jdbc-level attribute is used to specify the Jdbc compliance
- level of the used Jdbc driver.
-
- The eager-release attribute was adopt to solve a problem occured when
- using OJB within JBoss (3.0 <= version < 3.2.2, seems to be fixed in jboss 3.2.2).
- Only use within JBoss.
-
- The batch-mode attribute allow to set batch mode modus global
- from the used connection. It is also possible to change
- batch mode at runtime, using the
- PB.serviceConnectionManager.setBatchMode(...) method.
-
- The useAutoCommit attribute allow to set how OJB uses
- the autoCommit state of the used connections. The default mode
- was 1. When using mode 0 or 2 with the PB-api, you must use PB
- transaction demarcation.
- 0 - OJB ignores the autoCommit setting of the connection and do not
- try to change it. This mode could be helpfully if the
- connection don't let you set the autoCommit state
- (e.g. using datasources from application server).
- 1 - set autoCommit explicit 'true' when connection was created
- and temporary set to 'false' when necessary (default mode).
- 2 - set autoCommit explicit 'false' when connection was created.
-
- If the ignoreAutoCommitExceptions attribute is set 'true', all
- exceptions caused by setting autocommit state, will be ignored.
- Default mode 'false'.
-
- If a jndi-datasource-name for JNDI based lookup of Jdbc
- connections is specified, the four attributes driver, protocol,
- subprotocol, dbalias used for Jdbc DriverManager based construction
- of Jdbc Connections must not be declared.
-
- The username and password attributes are used as credentials
- for obtaining a jdbc connections.
- If users don't want to keep this information the
- repository.xml file, they could pass user/password
- using PBKey.java to obtain a PersistenceBroker

- The object-cache element can be used to specify the ObjectCache
- implementation used by OJB. There are three levels of

- maxActive
- maximum number of connections that can be borrowed from the

- max time block to get connection instance from pool, after that exception is thrown.
- When non-positive, block till last judgement
-
- whenExhaustedAction
- 0 - fail when pool is exhausted
- 1 - block when pool is exhausted
- 2 - grow when pool is exhausted
-
- testOnBorrow
- The pool will attempt to validate each object before it is returned from the pool
-
- testOnReturn
- The pool will attempt to validate each object before it is returned to the pool
-
- testWhileIdle
- Indicates whether or not idle objects should be validated.
- Objects that fail to validate will be dropped from the pool
-
- timeBetweenEvictionRunsMillis
- indicates how long the eviction thread should sleep before "runs" of examining
- idle objects. When non-positive, no eviction thread will be launched.
-
- minEvictableIdleTimeMillis
- specifies the minimum amount of time that a connection may sit idle
- in the pool before it is eligable for eviction due to idle time.
- When non-positive, no connection will be dropped from the pool due
- to idle time alone (depends on timeBetweenEvictionRunsMillis > 0)
-
- numTestsPerEvictionRun
- The number of connections to examine during each run of the

- logAbandoned
- Only supported when using
- org.apache.ojb.broker.accesslayer.ConnectionFactoryDBCPImpl
- ConnectionFactory implementation.
- Flag to log stack traces for application code which abandoned
- a Statement or Connection. Defaults to false. Logging of
- abandoned Statements and Connections adds overhead for
- every Connection open or new Statement because a
- stack trace has to be generated.
-
- removeAbandoned/removeAbandonedTimeout
- Only supported when using
- org.apache.ojb.broker.accesslayer.ConnectionFactoryDBCPImpl
- ConnectionFactory implementation.
- Flag to remove abandoned connections if they exceed the
- removeAbandonedTimeout. Set to true or false, default false.
- If set to true a connection is considered abandoned and
- eligible for removal if it has been idle longer than the
- removeAbandonedTimeout. Setting this to true can recover
- db connections from poorly written applications which
- fail to close a connection.

-
- The nullable attribute specifies if the column may contain null values.
-
- The indexed attribute specifies if there is an index on this column

-
- The updatelock attribute is set to false if the persistent attribute is
