Can we stop servers using batch file?
I am using Weblogic (v10) application server.
I want to stop the server or kill the process using batch file.
my application contains three Weblogic instances(Admin Server, Application Server ,Registration Server).
Please tell me how can we stop servers using batch file?
I believe it's possible to script all interactions with WebLogic instances, so my guess is "yes", it can be done.
Yes.
I think iv just found it on Google.
See Starting / Stopping WebLogic Server and notice that you will need to first setup your environment to use the Command-line Commands.

I have a SpringBoot Web server that sometimes shuts down itself when there is not enough memory on the machine.
So how can I automatically restart the application if that happens.
My approach would be to following:
Listen on the port 8080 where the server is running
If there is no more process on this port
Then I would restart the JAR file.
In which server have you your Spring boot running ?
In a linux distribution, you can manage it by using crontab to start at a wished hour and to stop the process too.
I use Weblogic server for my application and am trying to automate data source update task.
So, I have a script (UpdateDataSource.py) which updates the data source to what I need.
Now, I need Weblogic to restart once the data source has been updated. So I am trying something like;
call wlst UpdateDataSource.py
call startWebLogic.cmd
But my question is after I update the data source through script, I do not want to directly start the weblogic server (I need to close the existing one and then start)
How do I automate the same?
I'm not very sure about your question.
1. If you want to shutdown the WLS, use shutdown command in WLST
2. if you want to start WLS in another window, add "start" before the call command, like:
start call startWebLogic.cmd
I have a server installed in Heroku for my app, and now I want to install another Java-based server for my app for log purpose. How can I install a second server in Heroku?
Because this is going to be a different kind of server, the best option would be to create another heroku application for it.
But maybe you don't need to roll your own server to handle logs? Heroku already saves logs for a short period of time. You can view these logs with heroku logs command. There are addons to collect these logs and persist them for a longer period.
What is your way to debug Java side when nativeProcess.standardInput.write method is invoked by Flex side? I know that it is possible but don't know how?
To be able to attach your Eclipse debugger to a running Java process you need to start that process with the following Java options…
-Xdebug -Xrunjdwp:transport=dt_socket,address=8001,server=y,suspend=n
Once you have done this and have restarted the server, you can use your Eclipse to attach to the running process. From Eclipse go to the Debug manager and create a new Remote Java Application configuration for the process you want to connect to. Set the port number to 8001, the same as that of the options. You will also need to enter the hostname for the machine running the Java process. That is pretty much it…
I just want to know how I can start derby in network server mode and still be able to get an embedded connection?
Thank you.
You need to launch Derby in "embedded server mode". If you are already using Derby in embedded mode, this can be enabled by providing the necessary files in your classpath, then specifying a handful of command line arguments when launching the application.
First make sure the following jars are in your application's runtime classpath.
derby.jar derbynet.jar
Then add the following command line options to the Java command used to launch your application. If the class files are missing, these options will have no effect.
-Dderby.drda.startNetworkServer=true
-Dderby.drda.portNumber=8011
I'm running Derby from within a servlet hosted by Tomcat, so I added these options to the catalina.bat file.
Start up your application and check the list of open network sockets.
netstat -an | find "8011"
You should now see Derby listening for connections on 8011. Its now possible to connect to the database using Derby's client driver (derbyclient.jar). The instructions at http://docs.oracle.com/javadb/10.3.3.0/adminguide/radminembeddedserverex.html cover this part pretty well.
It was hinted that running Derby in this mode may be discouraged. I don't believe that to be the case. Your application will continue to access the database using the embedded driver, while other software is now permitted access using the client driver.
The Embedded Server mode sounds like what you are asking for. It allows you to start a network server when you start the embedded database.
It sounds contradictory that you want to start derby in network server mode and get the embedded driver. Even if this might be possible, it is definitely discouraged. You should decide on whether you want to use Apache Derby in the network mode using the DRDA or as an embedded driver and stick to that decision.
Here you'll find a tutorial on how to use the network driver:
http://db.apache.org/derby/papers/DerbyTut/ns_intro.html
Some one correct me if i am wrong, Both will run on separte ports. So you can connect to the required one using the proper connectionName, right?
#pawelocue: Sorry, but this is wrong. Using the embedded server mode is perfectly alright and sometimes very useful. It is definitely not discouraged.
