Starting or stopping an application server (JVM) will restart the application server and all of the application in the application server. Restarting the application server will not restart the node, deployment manager, or cell.
Web console
If the application server has been federated into the network deployment manager (dmgr), you canl use the dmgr to start or stop the application server.
- In the left panel of the WebSphere web console, expand Servers > Server Types.
- Select Websphere application servers.
- Check an application server, and select Start, Stop, Restart, ImmediateStop, or Terminate.
Following is a review of each option.
- Start - starts the application server
- Stop - lets in-flight requests complete before stopping the application server
- Restart - issues start followed by stop
- ImmediateStop - stops the application server without waiting for in-flight requests to complete - same as the kill -15 command.
- Terminate - kills the application server process
When the status of an application server is a green arrow icon, the application server is running.
When the status of an application server is a white x icon, the application server is in the process of being started or stopped.
When the stauts of an application server is a red x icon, the application server is stopped.
If the status of an application server is a question mark icon, the status of the application server is unknown. This is often due to the node being stopped.
Start Server - Command Line
The startServer.sh (Linux) or startServer.bat (Windows) command can be used to start an application server.
~]# was_home/profiles/your_profile/bin/startServer.sh server_name
The SystemOut.log file will contain "open for e-business" when the application server has started.
ADMU3000I: Server server1 open for e-business; process id is 12345.
Likewise, the serverStatus.sh (Linux) or serverStatus.bat (Windows) command can be used to check the status of an application server. The -all option can be used to display the status of every node and application server in the cell.
~]# was_home/profiles/your_profile/bin/serverStatus.sh server_name
. . .
ADMU0508I: The application server "server1" is STARTED.
On Linux, the ps command can be used to ensure the application server is running. In this example, the WebSphere application server is using PID 12345.
~]# ps -ef | grep -i WebSphere
root 12345 1 0 Dec13 ? 00:45:50 /opt/IBM/WebSphere/AppServer/. . .
On Linux, a crontab job can be created to ensure the deployment manager is started when the system is rebooted.
@reboot bash was_home/profiles/your_profile/bin/startServer.sh server_name
Stop Server - Command Line
The stopServer.sh (Linux) or stopServer.bat (Windows) command can be used to stop an application server.
~]# was_home/profiles/your_profile/bin/stopServer.sh server_name
The SystemOut.log file will contain "Server your_server stopped" when the application server has stopped.
WSVR0024I: Server server1 stopped
Likewise, the serverStatus.sh (Linux) or serverStatus.bat (Windows) command can be used to check the status of an application server. The -all option can be used to display the status of every node and application server in the cell.
~]# was_home/profiles/your_profile/bin/serverStatus.sh server_name
. . .
ADMU0509I: The application server "server1" cannot be reached. It appears to be stopped.
On Linux, the ps command can be used to ensure there are no WebSphere processes actively running. In this example, the ps command only returns one line, which is not the WebSphere application server, and instead just the ps command itself.
~]# ps -ef | grep -i WebSphere
root 12345 1234 0 18:51 pts/2 00:00:00 grep --color=auto WebSphere
