WE BSPHERE PORTAL V6.1 TUNING GUIDE

CLUSTER TUNING

The Base Portal Scenario is measured in a three-node horizontal cluster environment,

with or without session persistence, and six-members vertical cluster environment.

In general, the same tuning that was used for the Base Portal Scenario was used for

cluster. The additional settings are mentioned below:

Application Server Tuning

D Y N A C A C H E C U S T O M P R O P E R T I E S

There are several properties which can be set to reduce the number and size of

Dynacache messages sent between nodes. This will improve scalability and reduce

resource consumption in a clustered Portal environment. To set these properties, do the

following:

1) Open and log in to the Administrative Console.

2) Click Application servers -> WebSphere_Portal -> Java and Process

Management -> Process Definition -> Java Virtual Machine -> Custom

properties -> New

3) Under General Properties, add the following information:

Name: com.ibm.ws.cache.CacheConfig.ignoreValueInInvalidationEvent

Value: true

Name: com.ibm.ws.cache.CacheConfig.filterTimeOutInvalidation

Value: true

Name: com.ibm.ws.cache.CacheConfig.filterLRUInvalidation

Value: true

Z / O S D Y N A C A C H E C U S T O M P R O P E R T Y

A custom property has been defined:

com.ibm.ws.cache.CacheConfig.

propogateInvalidationsNotShared

, which when set to true leads to invalidations

being sent for cache entry insertions and updates for a NOT_SHARED cache instance.

This property should be removed on z/OS configurations as it has a major impact on

performance.
