Dynamic caching with scripting

You can configure dynamic caching with scripting and the wsadmin tool. Before starting this task, the wsadmin tool must be running. See the Starting the wsadmin scripting client article for more information.

Overview

If you use the wsadmin tool to enable servlet caching, make sure that portlet fragment caching is also enabled. Similarly if you use the wsadmin tool to disable servlet caching, make sure that portlet fragment caching is also disabled. The settings for these two caching functions must stay synchronized. If you enable or disable servlet caching using the administrative console, synchronization is automatically taken care of for you.

To see a list of parameters associated with dynamic caching, use the attributes command. For example:

$AdminConfig attributes DynamicCache

Procedure

1. Locate the server object. The following example selects the first server found:

   Using Jacl:

   set s1 [$AdminConfig getid /Server:server1/]

   Using Jython:

   s1 = AdminConfig.getid('/Server:server1/')
   

2. List the web containers and assign them to the wc variable, for example:

   Using Jacl:

   set wc [$AdminConfig list WebContainer $s1]

   Using Jython:

   wc = AdminConfig.list('WebContainer', s1)

3. Set the enableServletCaching attribute to true and assign it to the serEnable variable...

   Using Jacl:

   set serEnable "{enableServletCaching true}"

   Using Jython:

   serEnable = [['enableServletCaching', 'true']]

4. Enable caching...

   Using Jacl:

   $AdminConfig modify $wc $serEnable

   Using Jython:

   AdminConfig.modify(wc, serEnable)
