PersistenceBrokerFactoryClass=org.apache.ojb.broker.core.PersistenceBrokerFactoryDefaultImpl # If in managed environment *only* the PB-api was used it's recommended to use this factory # to enable the PersistenceBroker instances to participate in the JTA transaction.

Current version ships four implementations: # # 1. ConnectionFactoryNotPooledImpl # No pooling, no playing around. # Every connection request returns a new connection, # every connection release close the connection. # 2. ConnectionFactoryPooledImpl # This implementation supports connection pooling. # 3. ConnectionFactoryDBCPImpl # Using the jakarta-DBCP api for connection management, support # connection- and prepared statement-pooling, abandoned connection handling. # 4. ConnectionFactoryManagedImpl # Connection factory for use within managed environments - e.g. JBoss. # Every obtained DataSource was wrapped within OJB (and ignore # e.g. con.commit() calls within OJB). # Use this implementation e.g if you use Datasources from an application server. # # Use the OJB performance tests to decide, which implementation is best for you. # The proper way of obtaining a connection is configured in # JDBCConnectionDescriptor entries in the repository.xml file. # If want a more fine grained control of each connection pool used by OJB, # take a look at the repository.dtd, there was a possibility to override # this default connection factory entry in each JDBCConnectionDescriptor. # ConnectionFactoryClass=org.apache.ojb.broker.accesslayer.ConnectionFactoryPooledImpl #ConnectionFactoryClass=org.apache.ojb.broker.accesslayer.ConnectionFactoryNotPooledImpl #ConnectionFactoryClass=org.apache.ojb.broker.accesslayer.ConnectionFactoryManagedImpl #ConnectionFactoryClass=org.apache.ojb.broker.accesslayer.ConnectionFactoryDBCPImpl # # #---------------------------------------------------------------------------------------- # ConnectionManager #---------------------------------------------------------------------------------------- # The ConnectionManagerClass entry defines the ConnectionManager implemementation to be used ConnectionManagerClass=org.apache.ojb.broker.accesslayer.ConnectionManagerImpl # # #---------------------------------------------------------------------------------------- # SqlGenerator #---------------------------------------------------------------------------------------- # The SqlGeneratorClass entry defines the SqlGenerator implemementation to be used SqlGeneratorClass=org.apache.ojb.broker.accesslayer.sql.SqlGeneratorDefaultImpl # # #---------------------------------------------------------------------------------------- # IndirectionHandler #---------------------------------------------------------------------------------------- # The IndirectionHandlerClass entry defines the class to be used by OJB's proxies to # handle method invocations # IndirectionHandlerClass=org.apache.ojb.broker.core.proxy.IndirectionHandlerDefaultImpl # #---------------------------------------------------------------------------------------- # ListProxy #---------------------------------------------------------------------------------------- # The ListProxyClass entry defines the proxy class to be used for collections that # implement the java.util.List interface. # ListProxyClass=org.apache.ojb.broker.core.proxy.ListProxyDefaultImpl # #---------------------------------------------------------------------------------------- # SetProxy #---------------------------------------------------------------------------------------- # The SetProxyClass entry defines the proxy class to be used for collections that # implement the java.util.Set interface. # SetProxyClass=org.apache.ojb.broker.core.proxy.SetProxyDefaultImpl # #---------------------------------------------------------------------------------------- # CollectionProxy #---------------------------------------------------------------------------------------- # The CollectionProxyClass entry defines the proxy class to be used for collections that # do not implement java.util.List or java.util.Set. # CollectionProxyClass=org.apache.ojb.broker.core.proxy.CollectionProxyDefaultImpl # #---------------------------------------------------------------------------------------- # StatementManager #---------------------------------------------------------------------------------------- # The StatementManagerClass entry defines the StatementManager implemementation to be used StatementManagerClass=org.apache.ojb.broker.accesslayer.StatementManager # # #---------------------------------------------------------------------------------------- # StatementsForClass #---------------------------------------------------------------------------------------- # The StatementsForClassClass entry defines the StatementsForClass implemementation to be used # to implement cached statements.

LockManagerClass=org.apache.ojb.odmg.locking.LockManagerDefaultImpl # # The LockMapClass entry tells OJB which concrete LockMap # implementation is to be used. # If OJB is running on multiple concurrent clients it is recommended # to use the RemoteLockMapImpl. It guarantees to provide # Lockmanagement across multiple JVMs. # This Implemenation relies on a Servlet based Lockserver. To use it you have to # deploy the ojb-lockserver.war into a Servlet engine. # and you have to set the Property LockServletUrl to point to this servlet. # (see LockServletUrl section below). # If OJB is running in a single JVM (e.g. in a desktop app, or in a servlet # engine) it is save to use the InMemoryLockMapImpl. Using it will result # in a large performance gain. #LockMapClass=org.apache.ojb.odmg.locking.RemoteLockMapImpl LockMapClass=org.apache.ojb.odmg.locking.InMemoryLockMapImpl # # The LockTimeout entry defines the maximum time in milliseconds # that a lock may be hold. Defaults to 60000 = 1 minute LockTimeout=60000 # # The ImplicitLocking entry defines if implicit lock acquisition is # to be used. If set to true OJB implicitely locks objects to ODMG # transactions after performing OQL queries. # If implicit locking is used locking objects is recursive, that is # associated objects are also locked. # If ImplicitLocking is set to false, no locks are obtained in OQL # queries and there is also no recursive locking. ImplicitLocking=true #ImplicitLocking=false # # # The LockServletUrl entry points to the Lockserver servlet. # This Servlet is addressed by all distributed JVMs if the RemoteLockMapImpl # is used. LockServletUrl=http://127.0.0.1:8080/ojb-lockserver # # # The LockAssociations entry defines the behaviour for the OJB # implicit locking feature. If set to WRITE (default) acquiring a write- # lock on a given object x implies write locks on all objects associated # to x. If set to READ implicit read-locks are acquired. # Acquiring a read-lock on x thus allways results in implicit read-locks # on all associated objects. #LockAssociations=READ LockAssociations=WRITE # # #---------------------------------------------------------------------------------------- # OQL / SQL settings #---------------------------------------------------------------------------------------- # The OqlCollectionClass entry defines the collection type returned # from OQL queries. By default this value is set to DListImpl. # This will be good for most situations as DList allows maximum flexibility # in a ODMG environment. See also section 'ODMG settings'. # Using DLists for large resultsets may be bad for application performance. # For these scenarios you can use ArrayLists or Vectors. # Important note: the collections class to be used MUST implement the # interface org.apache.ojb.broker.ManageableCollection. # OqlCollectionClass=org.apache.ojb.odmg.collections.DListImpl_2 # OqlCollectionClass=org.apache.ojb.broker.util.collections.ManageableArrayList # OqlCollectionClass=org.apache.ojb.broker.util.ManageableVector # # The SqlInLimit entry limits the number of values in IN-sql statement, # -1 for no limits.
