Re: [Dspace-tech] Java out of memory error : urgent plz
Hi Baseer, If you have more memory available on the machine then allocate it to Tomcat. These are our settings, although we are running a number of installations of Dspace... JAVA_OPTS="-Xms3072m -Xmx3072m -XX:PermSize=256m -XX:MaxPermSize=256m... Cheers.

I picked up the following jsp page for revealing memory state you
could find useful. To use, put it in your webapps directory as `mem-
status.jsp' and point your browser at it. It is as follows:
1 <%@ page import="java.lang.management.*" %>
2 <%@ page import="java.util.*" %>
3
4
5 JVM Memory Monitor
6
7
8
9 Memory MXBean
10 Heap Memory Usage
12 <%=
13 ManagementFactory.getMemoryMXBean().getHeapMemoryUsage()
14 %>
15
16 Non-Heap Memory
17 Usage
18 <%=
19 ManagementFactory.getMemoryMXBean().getNonHeapMemoryUsage()
20 %>
21
22
23 Memory Pool MXBeans
24 <%
25 Iterator iter = ManagementFactory.getMemoryPoolMXBeans
().iterator();
26 while (iter.hasNext()) {
27 MemoryPoolMXBean item = (MemoryPoolMXBean)
iter.next();
28 %>
29
30
31 <%= item.getName() %>
32 Type<%= item.getType() %>
33 Usage<%= item.getUsage() %>
34 Peak Usage<%= item.getPeakUsage() %>
35 Collection Usage<%= item.getCollectionUsage
() %>

Please advise . Thank you, Baseer. -- Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
