Specifying running objects using the wsadmin scripting tool
Use scripting and the wsadmin tool to specify running objects.
Before you begin
Before starting this task, the wsadmin tool must be running. See the topic on starting the wsadmin scripting client.
About this task
You can run wsadmin commands that obtain object names and specify running objects.
Procedure
- 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)
Table 1. AdminConfig completeObjectName command description. Run the completeObjectName command with the template. Element Description 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]*. For more information, see Object name, Attribute, Attribute list. If there are several MBeans that match the template, the completeObjectName command only returns 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)
Table 2. AdminControl queryNames command description. Run the queryNames command with the template. Element Description 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 product 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]*
- Obtain the object name with the completeObjectName command,
for example:
- 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 topic on Jacl syntax.
Results
You can now use the running object in with other AdminControl commands that require an object name as a parameter.
