You specify the definition for using the caching functionality in the J2EE applications in the <configuration> tag of the logical J2EE server (j2ee-server) in the Easy Setup definition file. The following table describes the definitions for using the caching functionality specified in the Easy Setup definition file.

Table 2-35 Definitions for using the caching functionality

Specified parameters	Settings
ejbserver.jndi.cache	Specify whether to enable caching in naming.
ejbserver.jndi.cache.interval	Specify the interval (unit: seconds) for clearing the cache when caching is performed in naming.
ejbserver.jndi.cache.interval.clear.option	Determine the operations (cache-clearing range) for the cache area in naming after the lapse of the interval.

The following is an example of settings when the cache is cleared periodically (when the physical tier is defined).

Example:

<configuration>
 <logical-server-type>j2ee-server</logical-server-type>
 <param>
 <param-name>ejbserver.jndi.cache</param-name>
 <param-value>on</param-value>
 </param>
 <param>
 <param-name>ejbserver.jndi.cache.interval</param-name>
 <param-value>60</param-value>
 </param>
 <param>
 <param-name>ejbserver.jndi.cache.interval.clear.option</param-name>
 <param-value>check</param-value>
 </param>
 ... 
</configuration>

You specify the settings as properties when the EJB client application starts.

The method of setting the EJB client application properties differs depending on the commands used for starting the EJB client application.

• For the cjclstartap command
  When the cjclstartap command is used, you set up the properties in the properties file for the EJB client applications (usrconf.properties).
  
• For the vbj command
  When the vbj command is used, you set up the properties in the batch file/ shell script file, or the command arguments.
  

The following is an example of settings when the cache is cleared periodically.
