Error description
In the case where the servlet is defined with: <load-on-startup>1</load-on-startup> And these SMF settings enabled: server_SMF_request_activity_CPU_detail=1 server_SMF_request_activity_enabled=1 The servlet PMI stats are zero until the application is restarted
Local fix
restart application or disable server_SMF_request_activity_enabled
Problem summary
**************************************************************** * USERS AFFECTED: IBM WebSphere Application Server for z/OS * * version 8.5.5 and 9.0 users of servlets * * with PMI and SMF enabled. * **************************************************************** * PROBLEM DESCRIPTION: Missing PMI stats for servlets using * * load-on-startup while SMF enabled. * **************************************************************** * RECOMMENDATION: * **************************************************************** There is a condition during server startup where applications that have specified servlet load-on-startup and the server property server_SMF_request_activity_CPU_detail=1 defined will have missing Performance Monitoring Infrastructure (PMI) data for that servlet until the application is recycled. The issue is that load-on-startup causes the servlet to initialize PMI, but then the first System Management Facility (SMF) collection request at a point later in time also does PMI initialization resulting in the original PMI object to be lost.
Problem conclusion
This WebContainer fix resolves the PMI collection issue when both servlet load-on-startup in an application and SMF collection in the server are set. The fix for this APAR is currently targeted for inclusion in fixpack 8.5.5.20 and 9.0.5.8.
