An MDB pool processes each message at least once. Potentially, a message can be process more than once:
* If an application fails, a transaction rolls back, or the hosting server instance fail during or after the onMessage() method completes but before the message is acknowledged or committed, the message will be redelivered and processed again.
* Non-persistent messages are also redelivered in the case of failure, except for the case where the message\'s host JMS server shuts down or crashes, in which case the messages are destroyed.
To ensure that a message is processed exactly once, use container-managed transactions so that failures cause transactional MDB work to rollback and force the message to be redelivered.

There are two security conditions:
* time-constrained
* By Group or User

A: When using the create command with WLST online you must be connected to an Administration Server. B: Child types must be created under an instance of their parent type.
C: Syntax: create(name, childMBeanType, [baseProviderType])
The Create command creates a configuration bean of the specified type for the current bean.

Defining tuning parameters is not required in order to successfully deploy an application. If an application’s deployment descriptors and deployment plan do not define tuning parameters, WebLogic Server uses default values. The Administration Console automatically uses a deployment plan named plan.xml in the \\plan subdirectory of an application root directory if one is available.

When you shrink a data source, WebLogic Server reduces the number of connections in the pool to the greater of either the initial capacity or the number of connections currently in use.

In most of the architectures, the SSL is terminated at the hardware load balancer for performance reasons and allows the internal traffic to use HTTP for communication.

When using automatic service migration, the Node Manager is required to get health monitoring information about the member servers involved, as follows:
* Consensus leasing – Node Manager must be running on every machine hosting managed servers within the cluster.
* Database leasing – Node Manager must be running on every machine hosting managed servers within the cluster only if pre/post-migration scripts are defined. If pre/post-migrations are not defined, then Node manager is not required. References:

A: WLST online provides a variable, cmo, that represents the current management object. Example: wls:/mydomain/serverConfig/Servers/myserver/Log/myserver> cmo[MBeanServerInvocationHandler]mydomain:Name=myserver,Server=myserver,Type=
Log
B: wls:/mydomain/edit !> bean=getMBean(\'Servers/myserver/WebServer/myserver\') wls:/mydomain/edit !> print bean [MBeanServerInvocationHandler]mydomain:Name=myserver,Type=WebServer,Server=my server

The –remote argument indicates that weblogic.Deployer is not running on the same machine as the Administration Server, and that source paths specified in the command are valid for the Administration Server machine itself. If you do not use the -remote option, weblogic.Deployer assumes that all source paths are valid paths on the local machine.

There is no built-in mechanism for transferring files that a server depends on between machines. Using a disk that is accessible from all machines is the preferred way to ensure file availability. If you cannot share disks between servers, you must ensure that the contents of domain_dir/bin are copied to each machine.

With CLIENT_ACKNOWLEDGE the Session object relies on the application to call an acknowledge method on a received message. Once the method is called, the session acknowledges all messages received since the last acknowledge. References:

B: The nmStart command identifies the server instance to start. You define the number of restarts by setting the RestartMax property in a Node Manager startup.properties file. If you use the nmStart command with WLST connected to a Node Manager, Node Manager supports monitoring, stopping, and restarting the Administration Server.
C: The script named startManagedWebLogic can be used to start Managed Servers. On a UNIX system it is located in located in DOMAIN_NAME/bin/startManagedWebLogic.sh.

C: A callback handler used to control the failover and failback within a multi data source must include an implementation of the weblogic.jdbc.extensions.ConnectionPoolFailoverCallback interface.
D: You can register a callback handler with WebLogic Server that controls when a multi data source with the Failover algorithm fails over connection requests from one JDBC data source in the multi data source to the next data source in the list.

The Archive component of the WebLogic Diagnostics Framework (WLDF) captures and persists all data events, log records, and metrics collected by WLDF from server instances and applications running on them.
The Archive provides access interfaces so that the Accessor may expose any of the persisted historical data including logged event data and persisted metrics.

Not edit() navigates to the last MBean to which you navigated in the edit configuration MBean hierarchy or to the root of the hierarchy, DomainMBean.
StartEdit() starts a configuration edit session on behalf of the currently connected user. You must navigate to the edit configuration MBean hierarchy using the edit command before issuing this command.
Note: Click the Lock & Edit button to lock the configuration edit hierarchy for the domain. This enables you to make changes using the Administration Console.

The Expiration Policy log option removes expired messages from the system and writes an entry to the server log file indicating that the messages have been removed from the system. The actual information that is logged is defined by the Expiration Logging Policy.

testPool tests the connection pool in the data source by reserving and releasing a connection from it.
TestTableName is the name of the database table to use when testing physical database connections. This name is required when you specify a Test Frequency and enable Test Reserved Connections, Test Created Connections, and Test Released Connections.

This thread is considered Stuck by WebLogic because it\'s been running for over the time defined in MaxStuckThreadTime (600 seconds by default). Weblogic Server waits for this time to be reached before marking a thread as stuck if the thread is still working after this time.
Example: [STUCK] ExecuteThread: \'2\' for queue: \'weblogic.kernel.Default (self-tuning)\' id=73 idx=0x128 nid=13410 prio=1 alive, in native, daemon
