Specifying running objects using the wsadmin tool

Before starting this task, the wsadmin tool must be running. See the Starting the wsadmin scripting client article for more information.

Perform the following steps to specify running objects:

Obtain the configuration ID with one of the following ways:

Obtain the object name with the completeObjectName command, for example:

Using Jacl:

set var [$AdminControl completeObjectName template]

Using Jython:

var = AdminControl.completeObjectName(template)

where:

set is a Jacl command
var is a variable name
$ is a Jacl operator for substituting a variable name with its value
AdminControl is an object that enables the manipulation of MBeans running in a WebSphere server process
completeObjectName is an AdminControl command
template is a string containing a segment of the object name to be matched. The template has the same format as an object name with the following pattern: [domainName]:property=value[,property=value]*. See Object name, Attribute, Attribute list for more information.

If there are several MBeans that match the template, the completeObjectName command only retuns the first match. The matching MBean object name is then assigned to a variable.

To look for server1 MBean in mynode, use the following example:

Using Jacl:

set server1 [$AdminControl completeObjectName node=mynode,type=Server,name=server1,*]

Using Jython:

server1 = AdminControl.completeObjectName('node=mynode,type=Server,name=server1,*')

Obtain the object name with the queryNames command, for example:

Using Jacl:

set var [$AdminControl queryNames template]

Using Jython:
```
var = AdminControl.queryNames(template)
```

where:

set is a Jacl command
var is a variable name
$ is a Jacl operator for substituting a variable name with its value
AdminControl is an object that enables the manipulation of MBeans running in a WebSphere Application server process.
queryNames is an AdminControl command
template is a string containing a segment of the object name to be matched. The template has the same format as an object name with the following pattern: [domainName]:property=value[,property=value]*

If there are more than one running objects returned from the queryNames command, the objects are returned in a list syntax. One simple way to retrieve a single element from the list is to use the lindex command in Jacl and split command in Jython. The following example retrieves the first running object from the server list:
- Using Jacl:
```
set allServers [$AdminControl queryNames type=Server,*]
set aServer [lindex $allServers 0]
```
- Using Jython:
```
allServers = AdminControl.queryNames('type=Server,*')

# get line separator 
import  java lineSeparator = java.lang.System.getProperty('line.separator')

aServer = allServers.split(lineSeparator)[0]
```
For other ways to manipulate the list and then perform pattern matching to look for a specified configuration object, refer to the Jacl syntax.

ResultYou can now use the running object in with other AdminControl commands that require an object name as a parameter.
