I would like to use SEVERAL temporary directories, one for each tomcat server running. In my setup I have several BASE instances running, each in they own tomcat instance. I can setup up the tomcats to use different temporary directories (well, it does that by default so I am not really doing anything), but the problem occurs as soon as any of the BASE servers starts a plugin requiring temporary disk space. Independent of assigned tomcat temporary directories all plugins use /tmp. In the start up of the different tomcat servers, java.io.tmpdir is set to private tempdirs like /path/to/tomcat1/temp /path/to/tomcat2/temp (logs, conf, and ordinary tomcat stuff are set up similarly). The problem is that when tomcat/BASE starts a plugin execution the temporary directory is reset to /tmp. This could be that plugins runs in a ... jobagent ... which doesn't know anything about the temporary directory structure ... Hm, this is probably the issue. So, a new question. Can we tell the jobagents which temporary directory to use? I suppose a configuration parameter would solve it but dynamically on the fly? > > As far as I know the core is not using a temporary directory for > anything.
