Part 2: Automation

The operations team needs a WLST script to automate the creation of a new Managed Server and add it to the existing 'BankingCluster'. The script must handle the case where the server might already exist.

Below is a snippet of the script:

connect('weblogic', 'password', 't3://adminhost:7001')
edit()
startEdit()
cd('/')
if getMBean('Servers/NewServer') is None:
cmo.createServer('NewServer')
# MISSING CODE BLOCK
print 'Server created'
else:
print 'Server exists'
activate()

Which code block correctly assigns the new server to the cluster?

Accepted Answer

cd('/Servers/NewServer') cmo.setCluster(getMBean('/Clusters/BankingCluster'))

Answer

cd('/Servers/NewServer') set('Cluster', 'BankingCluster')

Answer

assign('Server', 'NewServer', 'Cluster', 'BankingCluster')

Answer

cd('/Clusters/BankingCluster') cmo.addServer('NewServer')

The domain must be configured with a backup Administration Server.

Answer

You must manually stop the Node Manager on each machine before running the command.

Question 10

You are troubleshooting a failed domain upgrade from 11g to 12c. The Reconfiguration Wizard failed during the JDBC configuration phase. You discover that the legacy domain used a deprecated JDBC driver that is no longer supported in 12c.

What is the correct procedure to resolve this issue and complete the upgrade?

Accepted Answer

Restore the 11g domain backup, remove or update the JDBC data sources to use a supported driver in the 11g environment, and then restart the upgrade process.

Answer

Continue the upgrade wizard by selecting the 'Ignore Errors' checkbox in the JDBC test screen.

Answer

Use the `commEnv.sh` script to append the old driver to the system classpath before running the Reconfiguration Wizard.

Answer

Manually copy the old driver JARs into the 12c `ORACLE_HOME/wlserver/server/lib` directory and restart the wizard.

Question 11

Case Study: **GlobalFin Banking - Domain Templating** GlobalFin Banking is standardizing its WebLogic environments. You need to create a Domain Template that will be used to deploy 50 new banking domains. The requirements are: 1. The template must include the Administration Server and two Managed Servers. 2. It must include a specific set of security provider configurations. 3. It must NOT include the `servers/AdminServer/logs` directory or any temporary files from the source domain. 4. The template creation must be automated. You are using the Domain Template Builder in console mode. How do you satisfy the requirement to exclude the log files?

Accepted Answer

Define a file filter in the Template Builder configuration to exclude the specific directory patterns.

Answer

Logs are automatically excluded by default; no specific action is required.

Answer

Manually delete the logs directory from the source domain before running the Template Builder.

Answer

Use the `-excludeLogs` flag when running the `pack` command.

Question 12

You have an existing basic WebLogic domain. You need to add Oracle Service Bus (OSB) functionality to this domain. You have installed the OSB software in the Middleware Home.

Which method should you use to add the OSB resources to your existing domain?
