Modify nested attributes using wsdmin.sh

We can modify nested attributes for a configuration object and wsadmin.sh.

The attributes for a WAS 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 containing a connectionPool attribute with a ConnectionPool type containing a variety of primitive attributes.

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

   See the topic on starting the wsadmin scripting client.

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

   Jacl:

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

   Using Jython:

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

   Element	Description
   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 product 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]]]]')

   Element	Description
   $	is a Jacl operator for substituting a variable name with its value
   AdminConfig	is an object representing the WAS 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:

   Jacl:

   $AdminConfig save

   Using Jython:

   AdminConfig.save()

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

Example

An alternative way to modify nested attributes is to modify the nested attribute directly.

Jacl:

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

Jython list:

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

Using Jython string:

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

In this example, the first command gets the configuration id of the DataSource, and the second command gets the connectionPool attribute. The third command sets the reapTime attribute on the ConnectionPool object directly.
