最近发现数据库出现
Exception [type: SIGSEGV, Address not mapped to object] [ADDR:0x2B5579043000] [PC:0x46B8A55, __intel_new_memcpy()+5429] [flags: 0x0, count: 1]
Incident 488910 created, dump file: /u01/app/oracle/diag/rdbms/jsdb/jsdb2/incident/incdir_488910/jsdb2_ora_9136_i488910.trc
ORA-07445: exception encountered: core dump [__intel_new_memcpy()+5429] [SIGSEGV] [ADDR:0x2B5579043000] [PC:0x46B8A55] [Address not mapped to object] []

然后发现bdump下的incident目录下，出现一个65G的dump文件，经查明发现是adr工具自动生成的。如果要等位系统问题所在，要读这个65G的dump文件吗，或者有什么更好的解决办法？

去查dump文件（/u01/app/oracle/diag/rdbms/jsdb/jsdb2/incident/incdir_488910/jsdb2_ora_9136_i488910.trc）头部就行，通常能看出是哪个代码引起了这个oracle bug。
然后去support.metalink.com查找ora-00600和ora-07445的查询工具页面,用这段信息进行查找，看看是打patch解决还是改写代码回避。

去查dump文件（/u01/app/oracle/diag/rdbms/jsdb/jsdb2/incident/incdir_488910/jsdb2_ora_9136_i488910.tr ...

这个是最新的错误对应的dump

我只复制了一部分，按照您说的，看头部，怎么确定问题呢？
