Various Ways to Remove Web Logic from Debug Port

August 23, 2020 by Larry Thomas

 

Here are some simple techniques to help you solve the debug port web logic problem.

There is no standard debug port for Weblogic. When starting Weblogic, you need to add the following parameter to your startup script. You can specify any port in the address and use that port (eg 4000) of Eclipse for remote debugging.

 

 

Hello everyone, and welcome to the new series of articles that Link Consulting's technical expert team will be releasing for Oracle Fusion Middleware in the coming months.

Introduction To Remote Debugging

Remote debugging uses TCP / IP communication between the JVM you are debugging and the tool of your choice to manage the debugging session.

There are two steps to debug a Weblogic instance using JDeveloper. First enable debugging on the JVM that Weblogic is running on, then configure JDeveloper to connect to the JVM.

Instructions

Step 1. Enable Remote Debugging On The Weblogic Server


What is socket in WebLogic?

Oracle WebLogic Server uses socket multiplexers, which are software modules for reading incoming requests to the server. Java multiplexer uses pure Java to read data from sockets, while native multiplexers use native platform-specific binaries.


We usually start Weblogic in development environments using the provided startWeblogic.sh startup script. Fortunately, this script already has the ability to run in debug mode.

The supplied startup scripts use port 8453 by default for debugging. If you want to use a different port, just set DEBUG_PORT as your environment variable.

In 12c, you can create / modify the $ DOMAIN_FOLDER / bin / setUserOverrides.sh file and add the required rewrite options. This is the file you should always use forAdding / changing launch parameters. If you are installing a patch or update, it should not be changed.

If you have multiple managed servers in your domain, you need to set different debug ports for each, otherwise only the first server will start. Indeed, the JVM refuses to start if the port is already in use. You can use the SERVER_NAME variable for this.



There is no setUserOverrides.sh in 11g. However, this can be added and executed at startup by modifying $ DOMAIN_FOLDER / bin / setDomainEnv.sh. This way you are safe when fixing or updating.


How do I start WebLogic in debug mode from command prompt?

To start WebLogic Server in debug mode, you must change startWebLogic. Cmd script in \\ wlserver_10. 0 \\ examples \\ domains \\ server_wl directory. is the directory where WebLogic 10.0 resides.


This is probably the easiest way to add debug flags, but the servers must be started by the node manager, including the administration server.

In the Weblogic console, select Environment-> Server from the left menu, then select the server for which you want to add debug flags from the list. Finally, select "Start Server".


What is the default port for WebLogic?

C. 1 port number per component
Component or Service default port number
Oracle WebLogic Server List Port for Administration Server 7001
Oracle WebLogic Server List Port for Managed Servers 8001
Oracle WebLogic Server Host Manager Port 5556
Oracle WebLogic Server SSL Monitoring Port for Administration Server 7002


Save changes and restart the server. It must be started using the node manager. The easiest way is also using the Weblogic console.


debug port weblogic

To check if debugs are active Lags, you can check the server log files or the current process arguments.

A new file is created each time Weblogic is started. So go to the beginning and look for the flags you added.

To indicate if a running Java process contains debug flags, simply run "ps uaxwww" and find the debug flags.

By enabling these flags, anyone who knows the address and port can connect to the JVM. This allows remote debugging as well as inserting code into a running JVM. Therefore, you should not enable these flags in a production environment.

After enabling these flags on your Weblogic instance, you can perform remote debugging using any JPDA-enabled tool.

This completes the server-side configuration. Our next article is about configuring your JDeveloper to use it. Looking forward to our next article!

Doesn't sound so bad. Let me tell you a few more benefits. The biggest problem for me was that I could enter the output window and the console at the same time: ...
