Work with application server properties files

We can use properties files to create or change application server properties and the associated StateManageable instance under a server.

Determine the changes to make to the application server configuration.

From the server profile bin directory, run wsadmin -lang jython

Using a properties file, we can create, modify, or delete an application server properties.

Run administrative commands using wsadmin to create or change a properties file for an application server, validate the properties, and apply them to the configuration.

properties files. We can create, modify, and delete

Action	Procedure
create	Not available
modify	Edit properties and then run the applyConfigProperties command.
delete	Not available
create Property	Set properties and then run the applyConfigProperties command.
delete Property	Run the deleteConfigProperties command.

Optionally, we can use interactive mode with the commands:

AdminTask.command_name('-interactive')

• Modify a properties file for an ApplicationServer object.

  1. Obtain a properties file for the application server to change.

     We can extract a properties file for an ApplicationServer using the extractConfigProperties command.

  2. Open the properties file in an editor and change the properties as needed.

     For example, modify the ApplicationServer and associated StateManageable under a server. The following properties file shows a property under ApplicationServer with name myName and value myVal:

     #
     # Header
     #
     ResourceType=ApplicationServer
     ImplementingResourceType=ApplicationServer
     ResourceId=Cell=!{cellName}:Node=!{nodeName}:Server=!{serverName}:ApplicationServer=
     AttributeInfo=components
     #
      #
     #Properties
     #
     applicationClassLoaderPolicy=MULTIPLE #ENUM(MULTIPLE|SINGLE),default(MULTIPLE)
     name=null
     applicationClassLoadingMode=PARENT_FIRST #ENUM(PARENT_FIRST|PARENT_LAST),default(PARENT_FIRST)
     server=!{serverName}
     parentComponent=null
     id=-1 #long,default(-1)
      
     #
     # Header
     #
     ResourceType=StateManageable
     ImplementingResourceType=ApplicationServer
     ResourceId=Cell=!{cellName}:Node=!{nodeName}:Server=!{serverName}:ApplicationServer=:StateManageable=
     AttributeInfo=stateManagement
     #
      #
     #Properties
     #
     initialState=START #ENUM(STOP|START),default(START)
     managedObject=Cell=!{cellName}:Node=!{nodeName}:Server=!{serverName}:ApplicationServer= #ObjectName(ApplicationServer),readonly
      
     #
     # Header
     #
     ResourceType=ApplicationServer
     ImplementingResourceType=ApplicationServer
     ResourceId=Cell=!{cellName}:Node=!{nodeName}:Server=!{serverName}:ApplicationServer=
     AttributeInfo=properties(name,value)
     #
      #
     #Properties
     #
     myName=myVal
     #
      EnvironmentVariablesSection
     #
     #Environment Variables
     cellName=WASCell06
     serverName=myServer
     nodeName=WASNode04

  3. Run the applyConfigProperties command to change an application server configuration and create any new properties.

     Running the applyConfigProperties command applies the properties file to the configuration. In this Jython example, the optional -reportFileName parameter produces a report named report.txt:

     AdminTask.applyConfigProperties(['-propertiesFileName myObjectType.props -reportFileName report.txt'])

• Delete application server properties.

  To delete one or more properties, specify only those properties to delete in the properties file and run deleteConfigProperties; for example:

  AdminTask.deleteConfigProperties('[-propertiesFileName myObjectType.props -reportFileName report.txt]')

Results

We can use the properties file to configure and manage the application server object.

What to do next

Save the changes to the configuration.

Subtopics

• Work with class loader properties files
  We can use properties files to create or change PARENT_LAST class loader properties under the ApplicationServer object of a server.

• Work with library reference properties files
  We can use properties files to create or change library reference properties under a PARENT_LAST class loader that is under the ApplicationServer object of a server.
