Java os porting tools

Some of the important commands for preliminary investigation apart from memory and CPU statistics are as follows. We can enable the JMX Remote ports by adding the following system parameters while starting the java application. The port mentioned in - Dcom. The stub is acquired from the RMI registry. Some of the datacenter and corporate network firewall prevents connectivity to the Random Ports due to security reasons. JDK 7 and above , provides a way to overcome this, by providing an option to set an additional system property, which will force the RMI server to open a predefined port instead of a Random generated Port.

We can also set the same port for both -Dcom. This will impact the application performance to a certain extent. Therefore, I would recommend monitoring the JVM and applying all the necessary fixes be done in the pre-prod environments and keep the production environment as light as possible.

Windows, Linux, MacOS. Most of the profiling tools like JProfiler, Yourkit, etc. Profiling agents written in Java can be loaded for instrumentation using the —javaagent VM option. We can build a lightweight custom instrumentation agent in Java by following simple steps. MF file of the JAR file, in which the agent and its dependent classes are bundled.

Since the premain method of the agent class is called before the main method of the application, -javaagent should always precede -jar. MF file. There are few articles that can provide more details about this technique. Here are some links for more information. It is significantly used for two purposes. It can be used during development, to build the code efficiently. The JVM creates a huge file with the name java. This contains information about heap profiles, allocated memories to instances, dynamic stack traces, etc.

HPROF can be run during compilation too javac. So that the developer can figure out the deficiencies in the code, even before running the application. Please refer the following links , which provides enough information with examples.

Running an application in debug mode is enabled by using the —agentlib:jdwp VM parameter. Dashboard Archived Portal Pages. Jira links. Created by Former Member on Feb 01, To Reset Administrator Password through Config Tool — It may sometimes happen that a user enters the wrong password a number of times by default, 3 and if that user is the administrator, then the administrator user is locked.
