![]() APAR status Closed as program error. Error description WebSphere J2EE Servers that are running HTTP Transport (also known as HTTP Catcher), may experience a problem where the application server region is not properly cleaned up when timer 'BBOC_HTTP_OUTPUT_TIMEOUT' expires. . When this timer 'pops' the server region should be ABENDed with an ABENDEC3 RC=04130001.Local fix Problem summary **************************************************************** * USERS AFFECTED: All users of WebSphere Application Server * * V4.0.1 for z/OS and OS/390 * **************************************************************** * PROBLEM DESCRIPTION: HTTP Transport processing for * * BBOC_HTTP_OUTPUT_TIMEOUT environment * * variable is not consistent with other * * recovery processing. * **************************************************************** * RECOMMENDATION: * **************************************************************** The HTTP Transport has a unique dispatch path through the Control region. This path differs from the GIOP workload in a number of ways. One difference is in the handling of timeouts and the cleanup of the related requests. For GIOP work queued to WLM for delivery to a Server Region (SR), a timer is started for the work based on the setting for OTS_MAXIMUM_TIMEOUT. If this timer expires prior to completion of the work in the Server region, the Control region will build exceptions into the Requests and abend the Server region (ABENDEC3, RC=04130001). This recovery action is not happening for HTTP Transport work. HTTP requests received over the HTTP Transport, where the BBOC_HTTP_OUTPUT_TIMEOUT related timer expired, are not interrupted and the associated SR is not abended. This does not allow control over long-running or looping requests from consuming system resources.Problem conclusion Code has been modified to make the HTTP Transport request timeout processing consistent with the GIOP request timer processing. When an HTTP request received over the HTTP Transport exceeds the timeout value specified by the environment variable BBOC_HTTP_OUTPUT_TIMEOUT, the HTTP request will be terminated as well as the associated Server region.
