Configure a Work Manager for the MDB with a Minimum Thread Constraint.

* When to Use Work Managers
Following are guildelines to help you determine when you might want to use Work
Managers to customize thread management:
/ The default fair share is not sufficient.
This usually ocurrs in situations where one application needs to be given higher priority
over another.
/ A response time goal is required.
/ A minimum thread constraint needs to be specified to avoid server deadlock

Comparing File Stores and JDBC-accessible Stores
The following are some similarities and differences between file stores and JDBCaccessible
stores:
* (A) JDBC stores may make it easier to handle failure recovery since the JDBC interface
can access the database from any machine on the same network. With the file store, the disk must be shared or migrated.
* The default persistent store can only be a file store. Therefore, a JDBC store cannot be
used as a default persistent store.
* Both have the same transaction semantics and guarantees. As with JDBC store writes,
file store writes are guaranteed to be persisted to disk and are not simply left in an
intermediate (that is, unsafe) cache.
* Both have the same application interface (no difference in application code).
* (not B, not E) All things being equal, file stores generally offer better throughput than a
JDBC store.
/ If a database is running on high-end hardware with very fast disks, and WebLogic Server
is running on slower hardware or with slower disks, then you may get better performance
from the JDBC store.
* File stores are generally easier to configure and administer, and do not require that
WebLogic subsystems depend on any external component.
* File stores generate no network traffic; whereas, JDBC stores generate network traffic if
the database is on a different machine from WebLogic Server.

Shut down the managed server from the WebLogic console.

Note:
* It is recommended that you shutdown WebLogic Server instances through the
Administration Console.
* If automatic server migration is enabled, the servers are required to contact the cluster
leader and renew their leases periodically. Servers will shut themselves down if they are
unable to renew their leases. The failed servers will then be automatically migrated to the
machines in the majority partition

Based on available examples of Filtering Classloader entries, try to modify get the
proper entries.

Note:
* The FilteringClassLoader provides a mechanism for you to configure deployment
descriptors to explicitly specify that certain packages should always be loaded from the
application, rather than being loaded by the system classloader. This allows you to use
alternate versions of applications such as Xerces and Ant.
* To configure the FilteringClassLoader to specify a certain package is loaded from an
application, add a prefer-application-packages descriptor element to the weblogicapplication.
xml which details the list of packages to be loaded from the application. The
following example specifies that org.apache.log4j.* and antlr.* packages are loaded from
the application, not the system classloader:
<prefer-application-packages>
<package-name>org.apache.log4j.*</package-name>
<package-name>antlr.*</package-name>
</prefer-application-packages>
