Modifying nested attributes with the wsadmin tool

The attributes for a WebSphere Application Server configuration object are often deeply nested. For example, a JDBCProvider object has an attribute factory, which is a list of the J2EEResourceFactory type objects. These objects can be DataSource objects that contain a connectionPool attribute with a ConnectionPool type that contains a variety of primitive attributes.

1. Invoke the AdminConfig object commands interactively, in a script, or use the wsadmin -c commands from an operating system command prompt.

2. Obtain the configuration ID of the object, for example:

   Using Jacl:

   set t1 [$AdminConfig getid /DataSource:TechSamp/]

   Using Jython:

   t1=AdminConfig.getid('/DataSource:TechSamp/')

   where:

   set	is a Jacl command
   t1	is a variable name
   $	is a Jacl operator for substituting a variable name with its value
   AdminConfig	is an object representing the WebSphere Application Server configuration
   getid	is an AdminConfig command
   DataSource	is the object type
   TechSamp	is the name of the object that will be modified

3. Modify one of the object parents and specify the location of the nested attribute within the parent, for example:

   Using Jacl:

   $AdminConfig modify $t1 {{connectionPool {{reapTime 2003}}}}

   Using Jython list:

   AdminConfig.modify(t1, [["connectionPool", [["reapTime", 2003]]]])

   Using
   Jython string:

   AdminConfig.modify(t1, '[[connectionPool [[reapTime 2003]]]]')

   where:

   $	is a Jacl operator for substituting a variable name with its value
   AdminConfig	is an object representing the WebSphere Application Server configuration
   modify	is an AdminConfig command
   t1	evaluates to the configuration ID of the datasource in step number 2
   connectionPool	is an attribute
   reapTime	is a nested attribute within the connectionPool attribute
   2003	is the value of the reapTime attribute

4. Save the configuration by issuing an AdminConfig save command. For example:

   Using Jacl:

   $AdminConfig save

   Using Jython:

   AdminConfig.save()

   Use the reset command of the AdminConfig object to undo changes that you made to your workspace since your last save.

Example

Using Jacl:

set techsamp [$AdminConfig getid /DataSource:TechSamp/]
set pool [$AdminConfig showAttribute $techsamp connectionPool]
$AdminConfig modify $pool {{reapTime 2003}}

techsamp=AdminConfig.getid('/DataSource:TechSamp/')
pool=AdminConfig.showAttribute(techsamp,'connectionPool')
AdminConfig.modify(pool,[['reapTime',2003]])

techsamp=AdminConfig.getid('/DataSource:TechSamp/')
pool=AdminConfig.showAttribute(techsamp,'connectionPool')
AdminConfig.modify(pool,'[[reapTime 2003]]')
