cmx_list_status (Display a status of service unit)

To acquire the status of the service unit in the Web system

This command acquires the service unit operating status and the executed status of the cmx_build_system command for the service unit and outputs the acquired results to standard output.

• Service unit operating status

  This command acquires the service unit executed status and outputs the acquired results to standard output. The following is the status that is output for the service unit operating status:

  • working

    Displays the operating status. This status indicates that all the logical servers in the service unit are running and that the requests are distributed from the load balancer (blockade status). In the absence of a load balancer, this status indicates that the cmx_start_target command is executed by specifying ALL in the -mode option.

  • ready

    Displays the ready status. This status indicates that all the logical servers in the service unit are running and that the distribution of requests from the load balancer is controlled (Blockade status). In the absence of a load balancer, this status indicates that the cmx_start_target command is executed by specifying READY in the -mode option.

    Normally, operations such as application testing are executed after changing the stopped status to the ready status, the application is not deployed, and the external connections are not established.

  • hold

    Displays the blockade status. This status indicates that the Web server in the service unit is terminated in a planned manner (another logical server is running) and the distribution of requests from the load balancer is controlled (Blockade status). Normally, operations such as substitution of J2EE applications are executed after changing the operating status to the blockade status.

    Note that the only difference between the blockade status and ready status is whether the Web server is running.

  • stopped

    Displays the stopped status. This status indicates that all the logical servers in the service unit are stopped and that the distribution of requests from the load balancer is controlled (Blockade status).

  • no working

    Indicates no working status. This status indicates that a part of the logical server in the service unit is running or all the logical servers have stopped, and the requests from the load balancer are distributed (Blockade cancellation status). This status is not output if the load balancer is not present.

  • no ready

    Indicates no ready status. This status indicates that the Web server in the service unit is stopped and a part of the other logical server is running, or the Web server in the service unit is running and a part of the logical server is running or all the logical servers have stopped, and the distribution of requests from the load balancer is controlled (Blockade status).

• Executed status of the cmx_build_system command.

  This command acquires the executed status of the cmx_build_system command for the service unit and outputs the acquired results to standard output as done (executed) and not done (not executed). Execution status of the cmx_build_system command that is output is as follows:

  • done

    Displays the executed status. This status indicates that the cmx_build_system command is executed, and the load balancer and the logical server are already set up.

  • not done

    Displays the executed status. This status indicates that an attempt to execute the cmx_build_system command has failed (any of the load balancer or the logical server is not setup or is not distributed).

If the service unit is specified in the command option, the specific service unit will be displayed and if the service unit is not specified in the command option, all the units in the Web system will be displayed.

To learn about the operating status of each J2EE application and each logical server, you use the mngsvrutil command. For details on the mngsvrutil command, see mngsvrutil (Management Server management command) in 7.2 Details of commands used with Management Server

To acquire the status of the logical server that is not associated with the Web system

• Logical server operating status

  This command acquires the status of the logical server and outputs the acquired results in the standard output. For the status that is output for the service unit operating state, see 4.4 Monitoring the logical server operations in the uCosminexus Application Server Management Portal User Guide.

• Executed status of the distribution of logical server preference information

  This command acquires the executed status of the distribution of logical server preference information and outputs the acquired result to standard output as done (executed) and not done (not executed). The status, specifying that the preference information be distributed, indicates the following types of status:

  • Status indicating that the cmx_build_system command was executed with the -ns option in the argument and the system setup was completed normally.
