Home -> Community -> Mailing Lists -> Oracle-L -> Re: smon 4030 - quick ideas?
Hi,
If you are on 10G you could be hitting bug 4970079 but without a pga heap dump or an errorstack I cannot confirm.
The following C program might tell you how much maximum memory a process can allocate on your box and then encounter a 4030.
Note : Since I don't have access to a system right now I haven't tested it
/* 4030 prog */
int main (int argc, char**argv) {
char * buff;
int mbCount = 0;
while (1) {
buff = (char *) malloc(1024*1024);
if (buff == (char *)0) {
printf("Out of memory\n");
exit(0);
printf("Allocated %d MB\n", mbCount);
}
}
Thanks
Fairlie

ORA-04030 means that the Oracle process attempted to allocate more memory for heap, similar to using the C "malloc()" function, so process limits could be very relevant...
