nofiles参数是可供进程使用的文件描述符的数目。当 IP:PIPE 或 IP:SPIPE 用于代理程序连接时,将维护每个代理程序的持久 TCP 连接,并且每个连接都需要一个文件描述符。如果文件描述符在需要时不可用,那么可能会发生意外行为,包括程序失败。对于 Tivoli Enterprise Monitoring Server 进程 (kdsmain),应该将nofiles参数...
nofile参数用于设置进程的最大打开文件描述符数(max number of open file descriptors)。文件描述符是用于访问文件或输入/输出设备的整数标识符。 修改进程打开文件描述符为 3 ┌──[root@liruilongs.github.io]-[~] └─$ulimit -n 1024 ┌──[root@liruilongs.github.io]-[~] ...
child: open file descriptors etc mother: use the fd's the child opened and vv. All of the above work because you aren't tied to the thread/process way of thinking. Think of a web server for example, where the CGI scripts are done ...
