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.

A web application is configured for in-memory replication and is deployed to a cluster. This cluster is distributed across two buildings on a university campus. For performance reasons, you require that session replication occur within the building whenever possible.

A WebLogic administrator is configuring a new dynamic cluster using a server template. This cluster will host two distinct types of applications: a high-volume, public-facing REST API and a low-volume, internal-only administrative tool. A key requirement is to isolate the network traffic for the public API from all other server traffic, including internal replication and JMX communication, for security and performance reasons. What is the most effective way to implement this traffic segregation for all servers generated by the dynamic cluster?

Correct answer: B
For dynamic clusters, configuration is inherited from the server template. The correct approach is to create a custom network channel with its own listen address and port dedicated to the public API traffic. By assigning this channel to the server template, all dynamic servers generated from that template will automatically be configured with this channel, effectively segregating the traffic. The default channel will handle other communications like JMX and replication. Configuring channels individually per server is not feasible for dynamic clusters. Using virtual hosts controls application mapping to hostnames but does not segregate traffic at the network level as effectively as channels do.

The admin server’s domain files were backed up by using the tar command on Linux. The admin server crashes and the domain files become corrupted. The domain files are restored from the backup. You try and start the admin server by using the usual domain start script. The script does not run. The error is “permission denied”.
How should you troubleshoot this?

You set up two network channels for server-to-server communication. You want channel X to be used more than channel Y, so you give channel X a higher Channel Weight. You want to see if indeed channel X is used more.
You use the administration console and look at both channels under each one’s Monitoring tab. What scenario would best assure you that channel X has an overall higher connection rate?
