Chapter 10. How to…
The following CLI commands and operations provide basic examples on how to accomplish certain tasks. For detailed instructions, see the appropriate section of the Configuration Guide or other JBoss EAP guide.
Unless specified otherwise, the examples apply when running as a standalone server. Use the --help argument on a command to get usage for that command. Use the read-operation-description to get information on a particular operation for a resource.
10.1. Add a Datasource
data-source add --name=DATASOURCE_NAME --jndi-name=JNDI_NAME --driver-name=DRIVER_NAME --connection-url=CONNECTION_URL
10.2. Add an Extension
Example: Add a New Extension to a Configuration
/extension=EXTENSION_NAME:add
10.3. Add a JMS Queue
jms-queue add --queue-address=QUEUE_NAME --entries=JNDI_NAME
10.4. Add a JMS Topic
jms-topic add --topic-address=TOPIC_NAME --entries=JNDI_NAME
10.5. Add a Module
module add --name=MODULE_NAME --resources=PATH_TO_RESOURCE --dependencies=DEPENDENCIES
Using the module management CLI command to add and remove modules is provided as Technology Preview only. This command is not appropriate for use in a managed domain or when connecting to the management CLI remotely. Modules should be added and removed manually in a production environment. For more information, see the Create a Custom Module Manually and Remove a Custom Module Manually sections of the JBoss EAP Configuration Guide.
Technology Preview features are not supported with Red Hat production service level agreements (SLAs), might not be functionally complete, and Red Hat does not recommend to use them for production. These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process.
See Technology Preview Features Support Scope on the Red Hat Customer Portal for information about the support scope for Technology Preview features.

}}
}
10.15. Display the Contents of an Attachment
You can use the attachment display command to display the contents of an attachment returned from a management operation. This applies to any management operation that returns the attached-streams response header.
For example, the following operation returns the server.log file attached as a stream.
/subsystem=logging/log-file=server.log:read-attribute(name=stream)
{
"outcome" => "success",
"result" => "f61a27c4-c5a7-43ac-af1f-29e90c9acb3e",
"response-headers" => {"attached-streams" => [{
"uuid" => "f61a27c4-c5a7-43ac-af1f-29e90c9acb3e",
"mime-type" => "text/plain"
}]}
}
You can use the attachment display command to display the contents of the stream returned form this operation to the console.
attachment display --operation=/subsystem=logging/log-file=server.log:read-attribute(name=stream)
This outputs the contents of the server.log file to the console.
ATTACHMENT f61a27c4-c5a7-43ac-af1f-29e90c9acb3e: 2017-08-14 15:20:01,472 INFO [org.jboss.modules] (main) JBoss Modules version 1.6.0.CR2-redhat-1 2017-08-14 15:20:01,721 INFO [org.jboss.msc] (main) JBoss MSC version 1.2.7.SP1-redhat-1 2017-08-14 15:20:01,853 INFO [org.jboss.as] (MSC service thread 1-8) WFLYSRV0049: JBoss EAP 7.1.0.GA (WildFly Core 3.0.0.Beta30-redhat-1) starting ...
10.16. Display Schema Information
To show the schema information for the :product-info command:
:read-operation-description(name=product-info)
To display the schema version, execute an ls command at the management CLI root and look for the management-*-version values:
... management-major-version=4 management-micro-version=0 management-minor-version=1 ...
10.17. Display System and Server Information
Example: Command to Display the System and Server Information
:product-info
Example: Output for the System and Server Information
{
"outcome" => "success",
"result" => [{"summary" => {
"host-name" => "HOST_NAME",
"instance-identifier" => "INSTANCE_ID",
"product-name" => "JBoss EAP",
"product-version" => "7.1.0.GA",
"product-community-identifier" => "Product",
"product-home" => "EAP_HOME",
"standalone-or-domain-identifier" => "OPERATING_MODE",
"host-operating-system" => "OS_NAME",
"host-cpu" => {
"host-cpu-arch" => "CPU_ARCH",
"host-core-count" => CORE_COUNT
},
"jvm" => {
"name" => "JAVA_VM_NAME",
"java-version" => "JAVA_VERSION",
"jvm-version" => "JAVA_VM_VERSION",
"jvm-vendor" => "JAVA_VM_VENDOR",
"java-home" => "JAVA_HOME"
}
}}]
}
Similarly, for a managed domain, you can display the information for a particular JBoss EAP host or server:
/host=HOST_NAME:product-info/host=HOST_NAME/server=SERVER_NAME:product-info
10.18. Get the Command Timeout Value
Example: Display the CLI Command Timeout Value

To reload the servers in a suspended state, pass in the start-mode=suspend argument.
10.23. Reload a Server
Example: Reload a Server in a Managed Domain
/host=HOST_NAME/server-config=SERVER_NAME:reload
To reload the server in a suspended state, pass in the start-mode=suspend argument.

10.25. Remove an Extension
Example: Remove an Existing Extension
/extension=EXTENSION_NAME:remove
10.26. Remove a Module
module remove --name=MODULE_NAME
Using the module management CLI command to add and remove modules is provided as Technology Preview only. This command is not appropriate for use in a managed domain or when connecting to the management CLI remotely. Modules should be added and removed manually in a production environment. For more information, see the Create a Custom Module Manually and Remove a Custom Module Manually sections of the JBoss EAP Configuration Guide.

10.27. Reset the Command Timeout Value
Example: Reset the Command Timeout to the Default Value
command-timeout reset default
Example: Reset the Command Timeout to the Value Provided by the CLI Configuration
command-timeout reset config
The value provided by the CLI configuration can be set in either in the EAP_HOME/bin/jboss-cli.xml file or passed in with the --command-timeout argument when starting the management CLI.

To restart the servers in a suspended state, pass in the start-mode=suspend argument.
10.29. Restart a Server
Example: Restart a Server in a Managed Domain
/host=HOST_NAME/server-config=SERVER_NAME:restart
To restart the server in a suspended state, pass in the start-mode=suspend argument.
10.30. Save the Contents of an Attachment
You can use the attachment save command to save the contents of an attachment returned from a management operation to a file. This applies to any management operation that returns the attached-streams response header.
For example, the following operation returns the server.log file attached as a stream.
/subsystem=logging/log-file=server.log:read-attribute(name=stream)
{
"outcome" => "success",
"result" => "f61a27c4-c5a7-43ac-af1f-29e90c9acb3e",
"response-headers" => {"attached-streams" => [{
"uuid" => "f61a27c4-c5a7-43ac-af1f-29e90c9acb3e",
"mime-type" => "text/plain"
}]}
}
You can use the attachment save command to save the contents of the stream returned form this operation to a file.
attachment save --operation=/subsystem=logging/log-file=server.log:read-attribute(name=stream) --file=log-output.txt
This saves the contents of the server.log file to EAP_HOME/bin/log-output.txt.
10.31. Set the Command Timeout Value

The host must be reloaded in order for the changes to take effect.
10.43. Upload an Attachment
You can upload a local file as an attachment to management operations that accept file streams. For example, the following management CLI command uses the input-stream-index option to upload the contents of a local file to an exploded deployment.
/deployment=DEPLOYMENT_NAME.war:add-content(content=[{target-path=/path/to/FILE_IN_DEPLOYMENT, input-stream-index=/path/to/LOCAL_FILE_TO_UPLOAD}]
