看到opiosq0函数,是操作系统抛出的异常,看看下面的 call stack:
Exception signal: 11 (SIGSEGV), code: 1 (Address not mapped to object), addr: 0x5a, PC: [0x3696c79, opiosq0()+81]
*** 2012-06-27 16:08:17.006
ksedmp: internal or fatal error
ORA-07445: exception encountered: core dump [opiosq0()+81] [SIGSEGV] [Address not mapped to object] [0x00000005A] [] []

同时在trace最后发现:WARNING:Could not increase the asynch I/O limit to 1152 for SQL direct I/O. It is set to 128
隐约感觉与隐含参数有关。
以上简要信息,想请教及各位的意建与建议。 |
