Subject Startup scripts - thoughts on PID file for Geronimo
Date Mon, 21 Nov 2005 06:32:47 GMT
PID file thoughts (long term enhancement)..

I noticed that in Tomcat 5.5.12 has the ability to store the 
PID in a file where the file name is supplied the CATALINA_PID 
environment variable.

I am wondering if geronimo's startup script could somehow get hold of 
the domain and server names for the Geronimo instance to be started.  
Geronimo's startup script could store the PID for Geronimo (when 
Geronimo is started)  in a file whose name is constructed using the 
domain and server names and stored in a central location that Geronimo 
knows how to find. 

This would enable one to look in a directory and see all the PIDs for 
Geronimo instances currently running.  This would allow us to create 
diagnostic/management scripts that can use this information.  It would 
also allow Geronimo itself to read the file to find the PID if we or any 
third party wanted to provide any integration of operating system 
information in the console (would only be available for operating 
systems where PID information is available).  Just thinking out loud...

When we are run multiple instances of Geronimo, where will users 
configure the domain and server names that are used as part of the GBean
