Use the wsadmin tool to extract or modify the properties
of an existing WCCM (WebSphere Common Configuration Model) object.
About this task
In previous releases of the product, extracted properties
only contained the most important properties of each object type.
You now can extract all the properties of any WCCM object, modify
the properties, and then validate and apply the modified properties
to a system configuration.
To extract WCCM object properties,
use the extractConfigProperties command and specify the WCCM object
identifier.
The extracted WCCM object properties file is not
portable among environments. If you intend to apply the properties
files to installations on different operating systems, you must modify
the extracted properties file to make it portable. See the topic on
applying portable properties files across multiple environments.
Also,
the extracted properties file does not contain nested objects. You
must extract the properties of each nested object independently.
For
each of the commands in this topic, you can run in interactive mode
by specifying the interactive parameter:
AdminTask.command_name('-interactive')
- Start the wsadmin scripting tool.
To start
wsadmin using the Jython language, run the following command from
the
bin directory of the server profile:
wsadmin -lang Jython
- Extract WCCM object properties using the createPropertiesFileTemplates
command.
For example, to extract properties for the
WCCM SIBus object mySib(cells/myCell04/buses/mySib|sib-bus.xml#SIBus_1250621844296) to
a file named mySIBus.props, run the following
command:
AdminTask.extractConfigProperties('mySib(cells/myCell04/buses/mySib|sib-bus.xml#SIBus_1250621844296)',
'[-propertiesFileName mySIBus.props ]')
The resulting mySIBus.props file
contains extracted properties such as the following:
#
ResourceType=SIBus
ImplementingResourceType=GenericType
ResourceId=Cell=!{cellName}:SIBus=!{sibus}
#
#
#Properties
#
secure=false #boolean,default(true)
uuid=1CAE88EF49150090
useServerIdForMediations=false #boolean,default(false)
name=mySib
interEngineAuthAlias=null
…
EnvironmentVariablesSection
#
#
#Environment Variables
sibus=mySib
cellName=myCell04
- Open an editor on the extracted properties file and modify
the extracted properties file as needed.
Ensure that
the extracted properties file provides suitable values for required
parameters.
- Apply the properties file using the applyConfigProperties
command.
For example, to apply the mySIBus.props properties
file, run following wsadmin command:
AdminTask.applyConfigProperties('[-propertiesFileName mySIBus.props]')
