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
- Start wsadmin
- Specify a running object.
- Use the attributes command to display the attributes of the running object:
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 - Use the operations command to find out the operations that are supported by the MBean:
orHelp.operations(MBeanObjectname)
Help.operations(MBeanObjectname, operationName)
where:
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:
$ 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
set server [$AdminControl completeObjectName type=Server,name=server1,*] $Help operations $server
server = AdminControl.completeObjectName('type=Server,name=server1,*')
print Help.operations(server)
To display detailed information about the stop operation, use the following example:
