![]() ![]() Once installation is complete you may re-run this command. Such as your system's IP address and operating system type and version When this tool interacts with package repositories, some system information To configure the tool to not check for updates, you can override theĭefault behavior via the tool's Preferences facility. If you choose to install Update Tool, your system will be automaticallyĬonfigured to periodically check for software updates. The software needed for this command (updatetool) is not installed. Note: your server needs internet access for /u01/app/glassfish/bin>./updatetool This will download and install the required software packages. If you didn’t install the Update Tool yet, you can do this by running the updatetool command in your glassfish/bin folder. I refer to the complete GlassFish 3.1.2 Upgrade Guide for more information.ġ) Upgrading GlassFish with the Update Tool I didn’t cover the upgrade of clusters in this blog post. In my environment, I have one domain administration server (DAS) and one local instance (“instance01”) under which Application Express 4.1.1 (APEX) is deployed. All these tools need to be installed first before they can be used. There are 3 ways to upgrade GlassFish v3.1.1 to v3.1.2: by using the graphical Update Tool, by using the graphical Software Update Notifier, or by using the command-line version of the Update Tool: pkg. */10 * * * * echo `date`>/tmp/glassfish_memory.log /u01/app/glassfish/bin/asadmin get -monitor -count-count>/tmp/glassfish_memory.logĮnvironment: GlassFish 3.1.1 Open Source Edition (Web Profile), Oracle Linux 6.2 64-bit, Application Express 4.1.1 The following example will execute every 10 minutes and write the datetime and the usedheapsize to a log file. To schedule the monitoring of memory statistics, you could easily add a command line entry to your crontab file. count-description = Amount of used memory in bytes Use the “get –monitor” subcommand to retrieve the required monitoring statistics.Īsadmin> get -monitor .* To view the JVM memory statistics, click on the blue arrow next to “JVM: Memory Statistics”. You should now see the Server Monitoring screen (see screenshot below). ![]() To specify the instance that you want to configure, add the “–target” option.Īsadmin> enable-monitoring -modules jvm=LOW -target myinstanceĬommand enable-monitoring executed successfully.Ĭlick on “Monitoring Data” in the left menu and then on “Server” (under “View Monitoring Data”) in the right menu. Use the subcommand “enable-monitoring” or “disable-monitoring” to enable/disable monitoring for a specific component. No instance restart is needed for this change. Set the Monitoring Level of the JVM component to “Low” and click on Save. You should now see the screen with the list of configurable components (see screenshot below). Now click on “Configure Monitoring” in the right menu for the instance you want to monitor. Start up the admin console (by default this runs on port 4848), log in as admin and click on “Monitoring Data” in the left menu. There are 2 ways to enable JVM monitoring: by using the graphical admin console, or from the command line by running the asadmin command. In this blog post I will explain how you can enable and monitor the memory statistics of the Java Virtual Machine in GlassFish 3.1.2. Environment: GlassFish OSE 3.1.2.2, Oracle Linux 6.3
