zpwu

如果jrocket有问题，需要dump内存，dump线程，可以直接使用命令jrcmd
cd /opt/jrockit-jdk1.6/bin
su - weblogic
./jrcmd 24803 help
./jrcmd 24803 hprofdump filename=/opt
./jrcmd 24803 heap_diagnostics > /tmp/a.out
./jrcmd 24803 command_line
./jrcmd 24803 print_object_summary
./jrcmd 24803 print_class_summary
./jrcmd 24803 print_codebloks
./jrcmd 24803 print_vm_state
./jrcmd 24803 heap_diagnostics
./jrcmd 24803 oom_diagnostics
./jrcmd 24803 print_memusage


查看gc情况可以使用
./jstat -options
./jstat -gc 24803
