WAS 5.1.2 - Dynamic cache

[Prasanthi Polavarapu]

Hi all,

We are using WSAD 5.1.2 for our project. For the implementation of dynamic cache, i need to create cache instances using the administrative console. The IBM product document details that the cache instances can be created by clicking Resources > Cache Instances in the admin console.

For reference see http://publib.boulder.ibm.com/infocenter/wasinfo/v5r1//index.jsp?topic=/com.ibm.wasee.doc/info/ee/ae/tdyn_distmap.html

In the above link, dynamic cache implementation is given and i am following the same.
As of Method 1 given in the article, i am not able to see the option Resources > Cache Instances in my admin console. Do i need some plugin or am i missing something for the implementation of dynamic cache.

Regards,
Prasanthi

The link you are looking is for WBI, which is the earlier version of process server.

You may want to look at this one which is for Websphere Application Server 5.1 version.

Hi,

According to the link given by anant (previous reply from anant) can't we use distributed map interface for dynamic cache implementation if it is websphere application server network deployment server 5.1?

Take a look at this doc on "WebSphere Dynamic Cache: Improving J2EE application performance", looks like you can do it. there is a code snippet too. Hope this helps.

DistributedMap interface. The DistributedMap interface
extends java.util.Map to access a cache instance.
Using the DistributedMap interface, J2EE applications
and system components can cache and
share Java objects by storing a reference to the object
in the cache. To store and retrieve objects in a
cache instance, a DistributedMap reference for the
named cache instance is needed.
