Hi,
Im using HP UX and tried to increase the JVM memory from 1GB to 2GB for the weblogic domain. but it did not work and started throwing errors. I would like to know if there is any OS level parameter that need to be checked and modified before making changes to JVM memory. (3 Replies)

Hi ,
Whenever I am starting JVM it is getting started with Xms as 256MB, which is 1/64 of the Memory available and by default this should happen.
But I want to change and start the every JVM with 128MB.
Is there any way to do or I have to manually specify Xms tag while starting JVM.
Thanks (1 Reply)

jvisualvm(1) General Commands Manual jvisualvm(1)NAME
jvisualvm - Java Virtual Machine Monitoring, Troubleshooting, and Profiling Tool
SYNOPSIS
jvisualvm [ options ]
PARAMETERS
Options, if used, should follow immediately after the command name. Options may be in any order. For a discussion of parameters that apply
to a specific option, see OPTIONS below.
DESCRIPTION
Java VisualVM is an intuitive graphical user interface that provides detailed information about Java technology-based applications (Java
applications) while they are running on a given Java Virtual Machine (JVM(*)). The name Java VisualVM comes from the fact that Java Visu-
alVM provides information about the JVM software visually.
Java VisualVM combines several monitoring, troubleshooting, and profiling utilities into a single tool. For example, most of the function-
ality offered by the standalone tools jmap, jinfo, jstat and jstack have been integrated into Java VisualVM. Other functionalities, such as
some of those offered by the JConsole tool, can be added as optional plug-ins.
OPTIONS
The following option is possible when you launch Java VisualVM.
-J<jvm_option>
Pass this <jvm_option> to the JVM software.
USAGE
Java VisualVM is useful to Java application developers to troubleshoot applications and to monitor and improve the applications' perfor-
mance. Java VisualVM can allow developers to generate and analyse heap dumps, track down memory leaks, perform and monitor garbage collec-
tion, and perform lightweight memory and CPU profiling. Plug-ins also exist that expand the functionality of Java VisualVM. For example,
most of the functionality of the JConsole tool is available via the MBeans Tab and JConsole Plug-in Wrapper plug-ins. You can choose from a
catalog of standard Java VisualVM plug-ins by selecting 'Tools' | 'Plugins' in the Java VisualVM menus.
Start Java VisualVM with the following command:
% jvisualvm <options>
