z/OS data collector: Request metrics and method trace data do not appear
The problem: When class preloading is enabled, request metrics and method trace data do not appear.
The solution: If class preloading is enabled for WebSphere on z/OS, then delete the .preload file for the WAS process when you change instrumentation in the bcm.properties or userbcm.xmlfilename files. When the process next starts up, a new class preload file is generated for your application classes based on the latest instrumentation.
To check whether class preloading is enabled verify whether -Dibm.websphere.preload.classes=true for Generic JVM arguments on the Java Virtual Machine page.
