Internal rpc error (error code:2). Please help.

Question

Our Oracle database is on Solaris 9. When we do stress testing on database and server. We have got this error message.
Monitor name :UNIX Resources. Internal rpc error (error code:2).
Hint: Check that RPC on this machine is up and running. Check that rstat daemon
on this machine is up and running (use rpcinfo utility for this verification).
Details: RPC: RPC call failed.
RPC-TCP: recv()/recvfrom() failed.
RPC-TCP: Timeout reached. (entry point: Factory::CollectData). [MsgId: MMSG-47197]
The error appears randomly when number of users querying database increases to high number.
Please help me to figure out the reason and solutions. Thanks in advance.

Answer 1

consider the following
not for copying
but for studying working code
to help clarify ideas
import java.io.*;
list items and count of each item
in a list of socks
file has list of socks ...
4
red sock
green sock
blue sock
green sock
the first line is n = count of socks
if no socks match, there are n items
for example : 3 items in ...
3
red sock
blue sock
green sock
if all socks match there is one item
for example : 1 item in ...
3
red sock
red sock
red sock
if socks come in pairs, there are at most n/2 items
for example : 2 items in ...
4
red sock
green sock
red sock
green sock
program does not assume that socks come in pairs !!
public class Socks {
public static void main(String args[]) throws IOException
String[] socks = new String[1000];
int numOfsocks;
String[] item = new String[1000];
int[] count = new int[1000]; // initializes each count to zero
int totalcount = 0;
int i;
int j;
boolean ifound;
FileReader fr = new FileReader("test.txt");
BufferedReader inFile = new BufferedReader(fr);
numOfsocks = Integer.parseInt(inFile.readLine());
for (i = 0; i < numOfsocks; i++)
socks[ i ] = inFile.readLine();
inFile.close();
for (i = 0; i < numOfsocks; i++) {
ifound = false;
for (j = 0; j < totalcount; j++) {
if (socks[ i ].equalsIgnoreCase(item[j])) {
ifound = true;
count[j]++; // increase count for matched item
break; // exit "for j loop"
} // for j
// sock not found so add it to item list ...
if (ifound == false) {
item[totalcount] = socks[ i ];
count[totalcount] = 1;
totalcount++;
} // for i
for (i = 0; i < totalcount; i++)
System.out.println (item[ i ] + ", count = " + count[ i ]);
} // class
