Errors in file /oracle/ora10g/admin/jscn/udump/jscn2_ora_28001.trc:

ORA-07445: exception encountered: core dump [_intel_fast_memcpy.A()+10] [SIGSEGV] [Address not mapped to object] [0x2B09D44BE000] [] []

Process 0x0x2d8367dc0 appears to be hung while dumping

Current time = 485605312, process death time = 485541208 interval = 60000

从上面的日志可以看出进程hung住，，让我查看/oracle/ora10g/admin/jscn/udump/jscn2_ora_28001.trc转存文件

/oracle/ora10g/admin/jscn/udump/jscn2_ora_28001.trc转存文件比较长，大概有5M，我们就看关键部分
