WebSphere App.Server 8.5.5 parametros de inicia de la JVM
Según como hayamos configurado la JVM del WebSphere App.Server puede que no inicie correctamente, en versiones posteriores al 7.0 determinar porque motivo la JVM no ha arrancado era una tarea algo complicada, a partir de la version 8.5.5 se ha facilitado dado que queda registado en el native_stderr.log los parámetros de arranque de la JVM, veamos el siguiente ejemplo:
