![]() APAR status Closed as program error. Error 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 back trace for serialization purposes. The corrected code now defers retrieiving the exception backtrace until the exception is serialized. So, if no serialization occurs, a large performance increase is observed when utilization the DistributedException class and its subclasses.Local fix Problem summary **************************************************************** * USERS AFFECTED: WebSphere Application Server Users of * * Command Exception * **************************************************************** * PROBLEM DESCRIPTION: The Websphere DistributedException * * class utilized too much CPU when * * creating an exception.
