Abstract
WebSphere® Application Server DistributedException class causing performance problem resulting in high CPU utilization.
 
Download Description
PQ69571 resolves the following problem:

PROBLEM DESCRIPTION:
The WebSphere DistributedException class utilized too much CPU when creating an exception. The extra CPU utilization was caused by the class retrieving the exception backtrace for serialization purposes. The corrected code now defers retrieving the exception backtrace until the exception is serialized. So, if no serialization occurs, a large performance increase is observed when utilizing the DistributedException class and its subclasses.

USERS AFFECTED:
WebSphere® Application Server Users of Command Exception.

PROBLEM CONCLUSION:
The corrected code now defers retrieving the exception backtrace until the exception is serialized. So, if no serialization occurs, a large performance increase is realized when utilizing the DistributedException class and its subclasses.
