Commands for troubleshooting

When we invoke the wladm program, we can include various commands for troubleshooting.

The show info command

The show info command shows basic information about the MobileFirst administration services that can be returned without accessing any runtime nor database. This command can be used to test whether the MobileFirst administration services are running at all.

Syntax:

show info

It takes the following options after the object:

Option	Description
--xml	Produce XML output instead of tabular output.

Example:

show info

The show versions command

The show versions command displays the MobileFirst versions of various components:

• wladmVersion: the exact MobileFirst Server version number from which worklight-ant-deployer.jar is taken.

• productVersion: the exact MobileFirst Server version number from which worklightadmin.war is taken

and for every project WAR file:

• serverVersion: the exact MobileFirst Server version number from which worklight-jee-library.jar is taken

• platformVersion: the exact version number of the MobileFirst development tools that built the project WAR file

Syntax:

show versions

It takes the following options after the object:

Option	Description
--xml	Produce XML output instead of tabular output.

Example:

show versions

The list runtimes command

The list runtimes command returns a list of the deployed runtimes (MobileFirst projects).

Syntax:

list runtimes [--in-database]

It takes the following options:

Option	Description
--in-database	Whether to look in the database instead of via MBeans
--xml	Produce XML output instead of tabular output.

Examples:

list runtimes list runtimes --in-database

This command is based on the Runtimes (GET) REST service.

The show runtime command

The show runtime command shows information about a given deployed runtime (MobileFirst project).

Syntax:

show runtime [runtime-name]

It takes the following arguments:

Argument	Description
runtime-name	Name of the runtime web application / MobileFirst project.

It takes the following options after the object:

Option	Description
--xml	Produce XML output instead of tabular output.

Example:

show runtime worklight

This command is based on the Runtime (GET) REST service.

The delete runtime command

The delete runtime command deletes a runtime, including its apps and adapters, from the database. It is only possible to delete a runtime when its web application is stopped.

Syntax:

delete runtime [runtime-name] condition

It takes the following arguments:

Argument	Description
runtime-name	Name of the runtime web application / MobileFirst project.
condition	Condition when to delete it: 'empty' or 'always' (dangerous!)

Example:

delete runtime worklight empty

This command is based on the Runtime (DELETE) REST service.
