WARNINGDO NOT modify any of these parameters unless you have read this property description. Incorrect settings can cause the Wrapper to fail to operate as expected. File to write the Wrapper process ID to. This property is not set by default. If this property is set, a file containing the pid of the Wrapper process will be written to the specified location when the process is launched. The file will be deleted when the Wrapper process has terminated. Common values are ./myapp.pid or /var/run/myapp.pid.
NOTEIf a second instance of the Wrapper is started, the pid file of the first instance will be overwritten by the second instance. This is done to avoid problems with stale pid files preventing the Wrapper from starting. On Linux/UNIX platforms, the shell script (sh) which is shipped with the Wrapper will prevent multiple copies of the Wrapper from running for the same application. It is possible to run multiple copies of the Wrapper on the same machine if some of Wrapper are each being used to launch a different application. In most cases, users will not need to set this property themselves. The UNIX shell script (sh) which is shipped with the Wrapper sets this property from the command line and then makes use of the pid in future invocations of the script. See the sh.script.in file in the src/bin directory for an example. The property is also available in the Windows version as some users have requested easy access to the pid for use by profiling tools. NOTEChanges to the value of this property will not have any affect on the Wrapper if the configuration is reloaded. The Wrapper must be restarted for changes to take effect. |
