Hi all, A mod_perl question if I may!
I have a cron job that schedules the execution of a mod_perl script (wget call). This script gathers various information about the linux system. I need to store some of this information in an area accessible by a separate mod_perl application. Ideally I would not want to use a database at all, I would prefer to use some "sort" of global variable - but am aware of the caching and copy on write affects of mod_perl. The mod_perl application will be receiving many requests a second, and will need to change its behaviour based on this stored system information (which will be updated by the cron job mod_perl script). My research so far has led me to believe that IPC::ShareLite could be used by the cron job script to set a few (very small) variables into a portion of shared memory, that a separate mod_perl application could poll. Mod_perl would not need to modify these variables, only read them. Would using a library such as IPC::ShareLite be considered a fudge for this type of action, is there some sort of global apache variable section that I can modify with one application and read out from another? Any thoughts appreciated! Ben Perl v 5.8.8 Apache 2.2.2 Mod_perl 2.0.2
