Error description New FunctionLocal fix Problem summary **************************************************************** * USERS AFFECTED: All users of WebSphere Application Server * * V4.0 for z/OS and OS/390 * **************************************************************** * PROBLEM DESCRIPTION: Support is required to allow * * transaction service restart and * * recovery on a peer system in a * * SYSPLEX. * **************************************************************** * RECOMMENDATION: * **************************************************************** In the event of a system failure, customers would like to configure ARM (and/or an automation product of their choice) to restart, on another (healthy) system in the same SYSPLEX, WebSphere servers that were running on the failed system. The goal of this restart is to resolve any in-doubt transactions that may have been active at the time of failure. Several issues with the run-time infrastructure would not allow this restart to take place.Problem conclusion If a WebSphere for z/OS server is started on a system to which it was not explicitly configured, it will place itself into peer restart and recovery mode. While in peer restart and recovery mode, a server will perform transaction service restart to provide outcomes to RRS and other OTS subordinates in the distributed transaction tree. In the event of communication errors that prevent restart from completing, diagnostic messages are written that contain enough information for customers to correct the connectivity problems, or to manually resolve the transaction branch with RRS. Once the restart and recovery is complete, the server will stop itself and terminate gracefully. A server in peer restart and recovery mode will not take on any new work. This restriction is designed to minimize the impact of CPU and storage requirements of server regions used to handle new requests. For information about the peer restart and recovery support provided in this APAR, a separate document, entitled "WebSphere Application Server V4.0.1 for z/OS and OS/390: Peer restart and recovery" is available for this APAR. To download the document, go to the following Web site, then click "Product information." http://www.ibm.com/software/webservers/appserv/zos_os390/ support.html At a later time, the information in this document will be integrated into the WebSphere for z/OS formal publications. To access the latest publications, go to the product library page at: http://www.ibm.com/software/webservers/appserv/ APAR PQ57396 is associated with SERVICE LEVEL W401042 of WebSphere Application Server V4.0.1 for z/OS and OS/390.Temporary fix Comments
