You might also see source code releases marked with the -src suffix, as well as RC release candidate and DR developer release versions of the server. Ignore those for now and stick to the production binaries. In this book we will work from the jboss If you are on a Unix machine, we suggest sticking with the.
Uncompress the download into the directory where you want JBoss installed, using the appropriate tool for your platform. You just installed one of the most powerful application servers available today.
Really powerful tools usually need much more setup and configuration, but not JBoss. You will want to check the firewall settings on that machine.
Be careful about installing JBoss on a machine that might be visible from the Internet. JBoss ships in an insecure state that allows external access to server management features. You might expect it to be complicated and time consuming to configure the server and get it running for the first time. There is a run. If your run.
Most of the services in JBoss log output as they start up. Additional log output is available in the server. JBoss is up and running. You should see the JBoss welcome page that looks similar to Figure The JBoss application server provides a management application that lets you see and manage the services that are deployed and running inside the server.
JBoss itself is implemented as a microkernel composed of managed beans MBeans. The MBeans that are visible provide you a way to manage the resources and applications that are deployed on your application server. This allows you to monitor and modify applications and their usage. When you select an MBean you are taken to a page where you can view and edit attributes or invoke the operations of that MBean.
If you provide MBeans for your own services, you will see them here too. JBoss provides an MBean that allows you to look at your server information. To do that now, scroll down in your browser until you get to the section for the jboss. It will look something like Figure If you are feeling adventurous, look at some of the other MBeans and see what other types of information are exposed. You also saw that the MBeans are organized according to the domain they are in.
While this might not seem like much now, it will come in handy as we work our way through the book. Now that you know how to start the server and look at it using the JMX Console, you need to know how to shut it down properly. You can shut down the server in three ways:. Use the JMX Console to go to the jboss. Type Ctrl-c in the same console window where you started JBoss. This also applies for web service requests associated with an XTS transaction.
By default, transaction graceful shutdown is disabled for the ejb subsystem. You must enable transaction graceful shutdown if you want the server to wait for EJB-related transactions to complete before suspending. For example:. The server will wait for all active jobs to finish. All queued jobs will be skipped. Currently, since EE Concurrency does not have persistence, those queued jobs that were skipped will be lost.
While the server is in a suspended state, scheduled tasks will continue to execute at their scheduled times but will throw a java. Once the server is resumed, scheduled tasks will continue to execute normally, and in most cases tasks will not need to be rescheduled.
Graceful shutdown currently will not reject new inbound JMS messages. EE batch jobs and EE concurrency tasks scheduled by in-flight activity are currently allowed to proceed; however, EE concurrency tasks submitted that pass the timeout window currently error when executed. Requests are tracked by the request-controller subsystem. Without this subsystem, suspend and resume capabilities are limited and the server will not wait for requests to complete before suspending or shutting down; however, if you do not need this capability, the request-controller subsystem can be removed for a small performance improvement.
JBoss EAP 7 introduced a suspend mode, which suspends server operations gracefully. This allows all active requests to complete normally, but will not accept any new requests. Once the server has been suspended, it can be shut down, returned back to a running state, or left in a suspended state to perform maintenance. The server can be suspended and resumed using the management console or the management CLI. The server suspend state can be viewed using the following management CLI commands.
Use the following management CLI commands to suspend the server, specifying the timeout value, in seconds, for the server to wait for active requests to complete.
The default is 0 , which will suspend immediately. A value of -1 will cause the server to wait indefinitely for all active requests to complete. The server can be returned back to a normal running state to accept new requests by using the resume command at the appropriate level server, server group, entire domain.
You can start a server in a suspended state so that no requests are accepted by the server until it is resumed. You can also pass the start-mode argument to the reload and restart operations for a server. You can also pass the start-mode argument to the reload-servers and restart-servers operations for a server group.
A server will be shut down gracefully if an appropriate timeout value is specified when stopping the server. Once the command is issued, the server will be suspended and will wait up to the specified timeout for all requests to finish before shutting down.
Use the following management CLI commands to shut down the server gracefully. Collectives on Stack Overflow. Learn more. How to check if JBoss is running on Unix server? Ask Question.
