#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;

{
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)
