![]() APAR status Closed as program error. Error description aditional functionLocal fix Problem summary **************************************************************** * USERS AFFECTED: All users of WebSphere Application Server * * version 4.0.1 for z/OS and OS/390 * **************************************************************** * PROBLEM DESCRIPTION: Need the ability to distribute a * * workload across multiple server * * regions before a heavy load occurs. * **************************************************************** * RECOMMENDATION: * **************************************************************** Currently, all http requests get routed to the same server region and establish HTTP Session Affinity to that server region. When a load is encountered from those same clients all the requests continue to get routed to the same server region due to the affinity. This undermines the usefullness of WLM and it's ability to add server regions and have them utilized.Problem conclusion Add support to the HTTP Transaction Class Mapping ability to map a single URI to multiple Transaction Classes. The customer can map those different Transaction Classes to different Service Classes to cause WLM to route the work to different server regions. The mapping will use a simple round robin algorithm. To activate the support, the environment variable must be set: BBOC_HTTPALL_TCLASS_ROUND_ROBIN=on If you wish to enable this functionality, please contact IBM Support for further information. APAR PQ81640 is associated with SERVICE LEVEL W401607 of WebSphere Application Server version 4.0.1 for z/OS and OS/390.Temporary fix Comments
