You configure a data source with a non XA driver because your (non-Oracle) database does not provide XA drivers.
The data source will sometimes participate in global transactions with an EJB, so as you configure the data source you select "Supports Global Transactions" and
One-phase commit.
Why is this configuration wrong?
Selecting 'One-Phase Commit' in a global transaction allows the data source to return 'ready' during the first phase of the two-phase commit process. This can lead to potential heuristic errors in the database, which makes the configuration problematic when dealing with global transactions involving multiple resources.
Which action should you take to automatically back up the domain configuration when anyone activates a configuration change?
To automatically back up the domain configuration when any configuration change is activated, you should select 'Configuration Archive Enabled' under the general configuration of the domain in the administration console. This action ensures that the domain configuration is archived each time a configuration change is made.
As the technical lead for your project, you have been asked to recommend a new solution to handle frequently increasing loads on your applications. The
WebLogic 12.1.2 domain currently runs with two clusters of three servers with request being filtered and passed by a proxy server that users the round ""robin algorithm.
However, the load sometimes exceeds the maximum capacity of all these servers combined but your domain lacks in scalability.
What is the best implementation solution?
To handle frequently increasing loads and improve scalability, configuring dynamic clusters and specifying the number of server instances needed at peak load is the best solution. This allows the system to automatically adjust the number of server instances based on the current load, ensuring that the application can handle higher traffic without manual intervention.
All administrators that deal with the production domain in your organization are extremely experienced. As the lead administrator, you have been asked to change the administration console preferences for all administrators so that inline help no longer displays, since no one needs it.
Select the true statement about this scenario.
Disabling inline help must be done on a per-user basis. This means that as the lead administrator, you cannot change the setting for all administrators at once. Each administrator needs to modify their own preferences individually to disable inline help.
You are working for a software company that mostly dealt with creating and reusing C++ and .NET objects. There are many COM (Component Object Model) components that have been created over time that provide standardized functionalities. Recently, platform independence has become a major consideration for your organization and you have deployed WebLogic Server12c. But you would like to make use of some of your prebuilt COM objects for request processing. You need an interim solution before implementing web services.
Which artifact within WebLogic Server helps you achieve your objective?
In a WebLogic Server environment that requires the use of prebuilt COM objects for request processing, the appropriate solution is to use the jCOM feature. jCOM is specifically designed to bridge Java with COM objects, allowing the integration and reuse of COM components within the WebLogic environment. It enables Java applications to interact with COM objects and vice versa, facilitating the use of existing COM components and providing a temporary solution until web services can be fully implemented.
