The following example shows the source code that you can use to increase the hard limit:
#include <sys/time.h> #include <sys/resource.h> #include <sys/types.h> /* ** define MAX_CONNECTIONS to a number less than ** 10000. The number defined will then become the maximum ** number of connections allowed by an Adaptive Server. */ #define MAX_CONNECTIONS 9999 extern int errno; main(argc,argv) char **argv; { struct rlimit rlp; uid_t uid; rlp.rlim_cur = MAX_CONNECTIONS; rlp.rlim_max = MAX_CONNECTIONS; /* set the number of open file desriptors to MAX_CONNECTIONS */ if (setrlimit (RLIMIT_NOFILE,&rlp) == -1) { perror("setrlimit"); exit(1); } /* reset the user id to disable superuser privileges */ uid = getuid(); setuid(uid); /* run the program indicated as arguments to this program */ execv(*++argv, argv); }
