Jprofiler Installation and Configuration

Ext.: http://www.cnblogs.com/adolfmc/archive/2013/06/09/3129358.html

Note: Use Rpm-q Jprofiler to find out if Jprofiler 1 is installed on Linux before installing. Download the Linux installation package to the official website, such as: JPROFILER_LINUX_7_1_1.RPM2. Upload the installation package to the LINXU server/ Opt directory, rename: MV jprofiler_linux_7_1_1.rpm jprofiler7.rmp (The rename step is optional, is for installation to generate a simple file directory Jprofiler7) 3. Installation: RPM-IVH Jprofiler_linux_7_1_1.rpm4. After the installation is complete, add the following in the Etc/profile: #Jprofiler Conf
Jprofiler_home=/opt/jprofiler7/bin/linux-x64
Export ld_library_path= $LD _library_path: $JPROFILER _home5. In the case of the Tomcat service, add the following in catalina.sh:
#Jprofiler Conf
java_opts= "$JAVA _opts-agentlib:jprofilerti=port=8849-xbootclasspath/a:/opt/jprofiler7/bin/agent.jar" 6. Added in startup.sh: #Jprofiler Conf
Catalina_opts= "-agentpath:/opt/jprofiler7/bin/linux-x64/libjprofilerti.so=port=8849,nowait$catalina_opts"
Export catalina_opts

1. Test environment
Server: RedHat Linux 3.4.3-9.el4 (kernel version 2.6.9-5.el), Tomcat5.5.20,sun JDK 1.5.0_09,jprofiler 4.3.2 for Linux (installation package: Jprofiler_ linux_4_3_2.sh)
Client: Windows Xp,jprofiler 4.3.2 for Windows (Installation package: Jprofiler_windows_4_3_2.exe)

2.JProfiler Software http://www.ej-technologies.com/

3. Client Jprofiler installed slightly

4. Server-side Jprofiler installation:
Upload the jprofiler_linux_4.3.2.sh to the server, assuming the path is/opt/jprofiler

# Cd/opt/jprofiler
# chmod +x *.sh
#./jprofiler_linux_4.3.2.sh-c
Follow the prompts to install, the tips are very simple, not much to say. Installation path Selection/opt/jprofiler4

Note that the-C meaning here is installed in character mode, if there is no X on the machine add this parameter.

5. Client Connection Configuration
1). Run Jprofiler. The first time you open a wizard, ignore it.
2). Select Session->integration wizard->new Remote integratation
3). Select on a remote computer;platform of remote computer select Linux X86/AMD 64;next
4). Enter the server IP; Next
5). Enter the installation path for the Jprofiler on the server, such as/opt/jprofiler4; next
6). Select the server's JDK environment, this is: Sun,1.5.0,hotspot;next
7). Input port: Here is the default value 8849;next
8). Select the startup mode: Here is the first wait for a connection from the Jprofiler Gui;next
9). The configuration that needs to be done on the server side is listed here:

Integration type: [Generic application]
Selected Jvm:sun 1.5.0 (hotspot)
Startup mode:wait for Jprofiler GUI

(1) Please insert

-agentlib:jprofilerti=port=8849-xbootclasspath/a:/opt/jprofiler4/bin/agent.jar

Into the start command of your remotes application right after the Java command.

(2) Please add

/opt/jprofiler4/bin/linux-x86

To the environment variable Ld_library_path.

A remote session named remote application on 192.168.40.15 would be is created that connects to a running instance of the Remo TE application that's started with the modified Start command.

6. Server-side configuration
(1) Modify the system environment configuration file/etc/profile, increase

Jprofiler_home=/opt/jprofiler4/bin/linux-x86
Export ld_library_path= $LD _library_path: $JPROFILER _home

(2) Modify Tomcat boot file catalina.sh, add-agentlib:jprofilerti=port=8849-xbootclasspath/a:/opt/jprofiler4/bin/agent.jar Content into the catalina_opts;
"-agentlib:jprofilerti=port=8849-xbootclasspath/a:/opt/jprofiler4/bin/agent.jar" This content is generated by the client software

catalina_opts= "$CATALINA _opts-xms128m-xmx128m $JPDA _opts-agentlib:jprofilerti=port=8849-xbootclasspath/a:/opt/ Jprofiler4/bin/agent.jar "

7.Reboot Linux and startup Tomcat using Startup.sh;
The log of Tomcat which is $CATALINA _home/logs/catalina.out'll show:

jprofiler> Protocol Version 23
Jprofiler> Using JVMTI
Jprofiler> 32-bit Library
Jprofiler> Listening on port:8849.
Jprofiler> Native Library initialized
Jprofiler> waiting for a connection from the Jprofiler GUI

8. Start the Client software
Click Jprofiler Menu Session>start center>open session
Available session configurations is listed in the connection just configured, check the use of OK!!

9.The log of Tomcat which is $CATALINA _home/logs/catalina.out'll show:

jprofiler> Using Dynamic Instrumentation
Jprofiler> Time measurement:elapsed Time
Jprofiler> CPU Profiling Enabled
jprofiler> Hotspot Compiler enabled
Jprofiler> starting Org/apache/catalina/startup/bootstrap

10. When the Jprofiler connection is interrupted
The log of Tomcat which is $CATALINA _home/logs/catalina.out'll show:

Jprofiler> disconnected. Waiting for reconnection.
Jprofiler> Listening on port:8849.
