Summary :
SAP Note addresses high CPU usage in J2EE Engine nodes, emphasizing the need to determine which Java thread(s) are utilizing CPU resources significantly. This situation involves neither direct solutions by JVMs to report thread-specific CPU usage nor simple identification methods due like race conditions which profiler introduction may obscure. The procedure includes obtaining CPU usage per thread at the OS level, getting a JVM thread dump, and correlating these two datasets. Platform-specific SAP Notes are referenced for detailed analysis per OS: 743207 for Windows, 743206 for Solaris/Sun OS, 743204 for HP-UX, 743191 for AIX, 743192 for Linux, and 1337417 for IBM i systems.
