Default values in version 9.0.3 have been modified as follows:
Lazy loading for CMP finder methods is now turned off as the default.
For relationship mapping for a one-to-many relationship, the default scenario used an association table. Now, the default is to use a foreign key. You can restore the previous behavior to use an association table by default by starting OC4J with the -DassociateUsingThirdTable=true
system property.
The default value for the trans-attribute
for CMP 2.0 entity beans is changed to Required
. For more information, see the JTA chapter in the Oracle Application Server Containers for J2EE Services Guide.
The JTA two-phase commit (2pc) function does not work with Oracle Database version 9.2. Instead, use Oracle Database version 9.2.0.4 or higher to enable the 2pc functionality.
The max-tx-retries
default value is zero. See the EJB section in the Oracle Application Server Performance Guide for more information.
The max-instances
default value is set to zero for all EJBs.
