Solaris (and any other operating system) will segregate different memory for each process that is running. In this case each instance of Analog that you start is independent and will run as its own process so the memory they use is segregated.
Analog is compiled in 32-bit mode by default and therefore can only reach 4GB of memory. If you re-compile in 64-bit mode (there are directions in the make file and possibly binaries in ports) then it can access more than 4GB of RAM (18 exabytes theoretically). I don't know a whole lot about how Solaris works, but guessing from their documentation<http://docsun.cites.uiuc.edu/sun_docs/C/solaris_9/SUNWdev/SOL64TRANS/p5.html>, it allocates one 32-bit virtual machine for all 32-bit apps, so multiple 32-bit versions of Analog will be fighting for the same 4GB of memory. -- Jeremy Wadsack Seven Simple Machines ________________________________ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Terry Chambers Sent: Wednesday, August 13, 2008 7:32 AM To: analog-help@lists.meer.net Subject: [analog-help] Running multiple reports on the same server We have a powerful Solaris server that has Analog installed on it (32GB of RAM). I have read the threads and it seem that Analog will only use 4GB of RAM unless you recompile it and change the memory settings. I am wondering what would happen if we ran Analog multiple times on the server. So far I have built configs and command lines for 5 different reports that I'd like run daily but I am scheduling them at intervals to prevent any issues. Any thoughts / opinions? Will multiple instances use the same 4GB of RAM or will the O/S distribute it out evenly? Thanks Terry
