WLSDM for WebLogic

The wlsdm update process is quite simple. wlsdm_agent.jar and wlsdm.war are replaced by new packages. The update steps are exactly as follows.

  1. Replace wlsdm_agent.jar file with the new release and keep wlsdm_agent.jar JVM arguments. *($JAVA_OPTIONS)
  2. Replace wlsdm.war file with the new release to WebLogic domain’s console-ext folder.
  3. (Re)start WebLogic managed server(s) then admin server.
  4. That’s all! WLSDM will be upgraded after restart processes.

While the update steps are very simple, things can get a little more difficult as the number of domains increases. This can create an extra workload for you. In this blog post…

We prepared WLSDM OID DevOps MBean blog about when OID shuts down due to external problems such as a network issue, the system will be provided to stand up. First of all, We are going to create WLSDM DevOps MBean then assign restart script on it. If the dummy LDAP search on DevOps MBean does not return any result, the opmnctl service will be restart by triggering the action script.

1. Creating Generic DevOps Mbean

1.1 Login to WebLogic console and go to WLSDM Console.

1.2 Go to “Configuration > Monitoring & Diagnostics”.

WLSDM new releases and updates come continuously, which will transform WLSDM into a unique viewing experience after upgrade. New update with ease of use and bug fixes; It brings the native WebLogic viewing experience offered to date to better levels. By upgrading the current WLSDM version, you can continue to use the WLSDM capabilities you are used to with the latest version.

1. WLSDM Upgrade and Patching Tutorial

1.1 Download latest WLSDM zip package and replace wlsdm_agent.jar

After unzipping the downloaded WLSDM zip, the wlsdm_agent.jar file needs to be placed in the server at $DOMAIN_HOME/wlsdm_agent/ , replacing the old file, by using the command below.

cp $wlsdm_package/jar/wlsdm_agent.jar $DOMAIN_HOME/wlsdm_agent/wlsdm_agent.jar

This operation should be repeated for all…

How to Stuck Thread Occurs?
A Stuck Thread is a thread which is processing a request for more than maximum time that you configured in WebLogic admin console. By Default, the WebLogic server comes with 600 secs. If some thread doesn’t return in 600 secs, It gets a flag ‘stuck thread’.

How to deal with Stuck Thread?
Take thread dumps instantly.
Open thread dumps in visualVM. Analyze dashboard from WebLogic console (managed server > monitoring > threads).
Open thread dump files in “WLSDM Menu > Monitoring & Diagnostics > Profiling Dumps”.

I have been working on WebLogic server for more than 9 years. Often, I monitor server log files, Server status, Testing Data source connections, JMS servers, deployed application status, CPU/Memory usage and much more. If any of these objects got down or broken, then the associated deployed application will get into trouble. For example, a web application dependent will go down if the associated Data source (DB Connection) goes down, or a deployed application give a poor response if the CPU/MEMORY is full.

Many times I thought, what if a tool available…

Performance metrics are standing in WLSDM menu’s “JVM System Resources” tab. Users can add or delete to metric; dashboard, action;

JVM System Resources

Previous on WLSDM blog, we have learned about WebLogic JMS infrastructure. In this tech blog post, let’s learn how to monitor WebLogic Java Virtual Machine (~Managed Server) resources and diagnose performance bottlenecks.

Weak JVM performance affects WebLogic domain performance directly. That’s why the host’s CPU and memory usage is very important in terms of improving WebLogic performance. Higher CPU consumption and Garbage Collection duration can cause applications to run slowly, even cause the WebLogic servers facing downtime. JVM instances in a WebLogic need to be monitored constantly and notification/alarm infrastructure must be installed as well. …
