strace 是Linux环境下的一款程序调试工具,用于检查一个应用程序所使用的系统调用以及它所接收的系统信息。strace会追踪程序运行时的整个生命周期,输出每一个系统调用的名字、参数、返回值和执行所消耗的时间等,是高级运维和开发人员排查问题的杀手铜。 strace命令的参数选项及说明 -c 统计每一个系统调用所执行的时间、...
ENOENT O_CREAT is not set and the named file does not exist. Or, a directory component in pathname does not exist or is a dangling symbolic link. 这里说得比较清楚,因为我们例子中的open选项指定了O_CREAT选项,这里errno为ENOENT的原因是日志路径中某个部分不存在或者是一个失效的符号链接。我们来一...
diagnosticians and trouble-shooters will find it invaluable for solving problems with programs for which the source is not readily available since they do not need to be recompiled in order to trace them. Students, hackers and the overly-curious will find that a great deal can be learned abou...
brk() sets the end of the data segment to the value specified by end_data_segment, when that value is reasonable, the system does have enough memory and the process does not exceed its max data size (see setrlimit(2)). 简单点说就是内存不够用时通过它来申请新内存(),可是为什么呢? shell...
PS C:\> Get-HgsTrace -Target $VMhost -Path ".\Traces"This command collects traces from the target specified in the VMhost variable. The command then stores the trace files to the specified path. Since the RunDiagnostics parameter is not used, the cmdlet does not run diagnostics against th...

内存不够用时通过它来申请新内存(data segment) 「man brk」来查询一下它的含义: brk() sets the end of the data segment to the value specified by end_data_segment, when that value is reasonable, the system does have enough memory and the process does not exceed its max data size (see setr...

Therefore, the maximum row size is 56 (30+2+22+2). To perform array operations for 100 rows, a buffer size of 5600 should be specified. 如果说number的字段值有多大,相比varchar2就小很多了。 个人感觉可能是一个bug. 至于为什么buffer设置到9M导出这个表就慢,到底慢在哪儿了?还可以通过strace来做...
