Identifying attributes and operations for running objects with the wsadmin tool

 

Overview

Use the attributes or operations commands of the Help object to find information on a running MBean in the server.

 

Procedure

  1. Start wsadmin

  2. Specify a running object.

  3. Use the attributes command to display the attributes of the running object:

    • Jacl

      $Help attributes MBeanObjectName
      

    • Jython

      Help.attributes(MBeanObjectName)
      

    where:

    $ is a Jacl operator for substituting a variable name with its value
    Help is the object that provides general help and information for running MBeans in the connected server process
    attributes is a Help command
    MBeanObjectName is the string representation of the MBean object name that is obtained in step 2

  4. Use the operations command to find out the operations that are supported by the MBean:

    • Jacl

      $Help operations MBeanObjectname
      
      or
      $Help operations MBeanObjectname operationName
      

  • Jython

    Help.operations(MBeanObjectname)
    
    or
    Help.operations(MBeanObjectname, operationName)
    

    where:

    $ is a Jacl operator for substituting a variable name with its value
    Help is the object that provides general help and information for running MBeans in the connected server process
    operations is a Help command
    MBeanObjectname is the string representation of the MBean object name that is obtained in step number 2
    operationName (optional) is the specified operation from which you want to obtain detailed information
    If you do not provide the operationName value, all the operations that are supported by the MBean return with the signature for each operation. If you specify the operationName value, only the operation that you specify returns and it contains details which include the input parameters and the return value. To display the operations for the server MBean, use the following example:

    To display detailed information about the stop operation, use the following example:
