IBM WebSphere sMash management tasks reference
This topic contains an alphabetical list of the management commands that can be performed on any WebSphere sMash application. To issue these commands, your working directory should be the root directory of the application, or any directory below the root directory of the application.
info
- Description
-
Usage
- zero info
Retrieves the basic information required to access the application when it is in the running state. This usually includes the base URL and port numbers for the application once started but may include HTTPS settings or other information.
recycle
- Description
-
Usage
- zero recycle
Causes the application runtime to be recycled. The Java™ runtime process exits. The Java™ runtime process will not be started again until the new request is received, unless the immediateStart option is enabled in configuration. A recycle can be performed while the application is servicing requests.
There is no resolve step in the recycle of an application. While the recycle command is faster than separate stop and start commands, many changes to the configuration of the application are not picked up. It is recommended that for configuration changes, the application be stopped then started.
start
- Description
-
Usage
- zero start [-fg]
Starts the application. The application should be successfully resolved before it is started.
The application is normally started in the background. The fg, or foreground option, will start the application in the foreground in the current terminal window.
stats
- Description
-
Usage
- zero stats
Retrieves the current statistics for the application. The statistics available are dependent on the operating system and Java™ runtime environment that the application is using, but include information the following functions:
- Request statistics
- Java™ runtime heap and memory
- Operating system process resource
status
- Description
-
Usage
- zero status
Retrieves the current state of the application. Valid states are STOPPED, STARTED, and UNKNOWN. UNKNOWN can occur if the application has a running process associated with it but it can not be reached using its base URL as reported by the info command.
stop
- Description
-
Usage
- zero stop [-force]
Stops an application that is running.
Normally, the stop functions by connecting to the application and requesting that it stop. However, if the application is no longer responding to requests, the force option can be used to kill the application's processes.
