Obtaining online help using scripting

 

You can select from three levels of online help for administrative commands.

 

Overview

The top-level help provides general information for the AdminTask object and associated commands. The second-level help provides information about all of the available administrative commands and command groups. The third-level help provides specific help on a command group, a command, or a step. Command group-specific help provides descriptions for the command group specified and the commands that belong to the associated group. Command-specific help provides description for the specified command, and associated parameters and steps. Step-specific help provides a description for the specified step and the associated parameters. For command and step-specific help, required parameters are marked with an asterisk (*) in the help output.

 

Procedure

• To obtain general help, use the following examples: Using Jacl:

  $AdminTask help
  

  Use Jython:

  print AdminTask.help()
  

  Example output:

  WASX8001I: The AdminTask object enables the execution of available
             admin commands. AdminTask commands operate in two modes:
             the default mode is one which AdminTask communicates with the
             WebSphere server to accomplish its task. A local mode is also 
             available in which no server communication takes place. The local
             mode of operation is invoked by bringing up the scripting client
             using the command line "-conntype NONE" option or setting the
             "com.ibm.ws.scripting.connectiontype=NONE" property in
             wsadmin.properties file.
  
  The number of admin commands varies and depends on your WebSphere install. 
  Use the following help commands to obtain a list of supported commands  and their parameters:
   help -commands
              list all the admin commands help -commandGroups    
              list all the admin command groups help commandName 
              display detailed information for
                the specified command help commandName stepName    
              display detailed information for
              the specified step belonging to 
              the specified command help commandGroupName  
              display detailed information for
                 the specified command group
  
  There are various flavors to invoke an admin command:
   commandName    
              invokes an admin command that does not require any argument. 
   commandName targetObject  
              invokes an admin command with the specified target object 
              string, for example, the configuration object name of a 
              resource adapter. The expected target object varies with 
              the admin command invoked. Use help command to get 
              information on the target object of an admin command.
   commandName options       
              invokes an admin command with the specified option 
              strings. This invocation syntax is used to invoke an 
                 admin command that does not require a target object. It 
                 is also used to enter interactive mode if "-interactive" 
                 mode is included in the options string.
   commandName targetObject options  
              invokes an admin command with the specified target 
              object and options strings. If "-interactive" is 
              included in the options string, then interactive mode 
              is entered. The target object and options strings vary 
              depending on the admin command invoked. Use help 
              command to get information on the target 
              object and options.
  
  

• To list the available command groups, use the following examples: Using Jacl:

  $AdminTask help -commandGroups
  

  Using Jython:

  print AdminTask.help(‘-commandGroups’)
  

  Example output:

  WASX8005I: Available admin command groups:
  
  ClusterConfigCommands - Commands for configuring application  server clusters and cluster members.
  JCAManagement - A group of admin commands that helps to configure 
  Java2 Connector Architecture(J2C) related resources.
  
  

• To list the available commands, use the code in the following examples: Using Jacl:

  $AdminTask help -commands
  

  Use Jython:

  print AdminTask.help(‘-commands’)
  

  Example output:

  WASX8004I: Available administrative commands:
  
  copyResourceAdapter - copy the specified J2C resource adapter to the specified scope createCluster - Creates a new application server cluster.

  listJ2CActivationSpecs - List the J2C activation specifications that have a  specified message listener type defined in the specified J2C resource adapter.
  

• To obtain help about a command group, use the following examples: Using Jacl:

  $AdminTask help JCAManagement
  

  Use Jython:

  print AdminTask.help(‘JCAManagement’)
  

  Example output:

  WASX8007I: Detailed help for command group: JCAManagement  Description: A group of administrative commands that help to  configure Java 2 Connector Architecture (J2C)-related resources.

  listJ2CActivationSpecs - List the J2C activation specifications that  have a specified message listener type defined in the  specified J2C resource adapter. 
  copyResourceAdapter - copy the specified J2C resource  adapter to the specified scope.
  

• To obtain help about an administrative command, use the following examples: Using Jacl:

  $AdminTask help createJ2CConnectionFactory
  

  Using Jython:

  print AdminTask.help(‘createJ2CConnectionFactory’)
  

  Example output:

  WASX8006I: Detailed help for command: createJ2CConnectionFactory
  
  Description: Create a J2C connection factory  *Target object: The parent J2C resource adapter of the created J2C connection factory.
  
  Arguments:
  *connectionFactoryInterface - A connection factory interface that is defined in the deployment 
      description of the parent J2C resource adapter.
  *name - The name of the J2C connection factory.
  *jndiName - The JNDI name of the created J2C connection factory. description - The description for the created J2C connection factory. authDataAlias - the authentication data alias of the created J2C connection factory.
  
  Steps:
  None
  
  

  In the command-specific help output that is previously listed, an administrative command is divided into three input areas: target object, arguments, and steps. Each area can require input depending on the administrative command. If an area requires input, each input is described by its name and a description; except for the target object area, which contains the description of the target object only. When you use an administrative command in batch mode, you can use any input name that resides in the argument area as the argument name. If an input is required, an asterisk (*) is located before the name. If an area does not require an input, it is marked None. The following example uses the help output for the createJ2CConnectionFactory command:

  • The target object area requires the configuration object name of a J2CResourceAdapter.

  • In the arguments area, there are five inputs with three being required inputs. The argument names are connectionFactoryInterface, name, jndiName, description, and authDataAlias. These names are used as the parameter names in the option string to run an administrative command in batch mode...

    -connectionFactoryInterface javax.resource.cci.ConnectionFactory -name newConnectionFactory 
    -jndiName CF/newConnectionFactory
    

    See Administrative command invocation syntax for more information about specifying argument options.

  • No step is associated with this administrative command.

• To obtain help on a command step, use the step-specific help. Step-specific help provides the following data:

  • A description for the command step.

  • Information indicating if this step supports collection. A collection includes objects of the same type. In a command step, a collection contains objects that have the same set of parameters.

  • Information regarding each step parameter with its name and description. If a step parameter is required, an asterisk (*) is located in front of the name.

  The following example obtains help on a command step:

  Using Jacl:

  $AdminTask help createCluster clusterConfig
  

  Use Jython:

  print AdminTask.help(‘createCluster’, ‘clusterConfig’)
  

  Example output:

  WASX8013I: Detailed help for step: clusterConfig
  
  Description: Specifies the configuration of the new server cluster.
  
  Collection: No
  
  Arguments:
    *clusterName - Name of server cluster.
    preferLocal - Enables node-scoped routing optimization for the cluster.
  
  

  This example indicates the following information about the clusterConfig step:

  • This step does not support collection. Only one set of parameter values for the clusterName and perferLocal parameters is supported.

  • This step contains two input arguments with one argument that is indicated as required. The required arguments is clusterName and the non-required parameter is preferLocal. The syntax to provide step parameter values is different from the command argument values. You have to provide all argument values of a step and provide them in the exact order as displayed in the step specific help. For any optional argument that you do not want to specify a value, put double quotes ("") in place of a value. If a command step is a collection type, for example, it can contain multiple objects where each object has the same set of arguments, you can specify multiple objects with each object enclosed by its own pair of braces. To run an administrative command in batch mode and to include this step in the option string, use the following syntax:

    Using Jacl:

    -clusterConfig {{newCluster false}}
    

    Use Jython:

    -clusterConfig [[newCluster false]]
    

    See Administrative command invocation syntax for more information about specifying parameter options.
