If you are going to install the Optimize Analytic Engine on a UNIX system, make sure you have set sufficient user limits for the shell you use to start the installation and the product daemons. For example, the daemons for the Optimize infrastructure will run out of memory if they are started from the shell with a low user limit for data. If your system policy allows it, Software AG recommends setting the value for coredump, data, file, memory, and threads to at least 32768, and the value of nofiles to 8192. For more information about setting and displaying the ulimits, read the man page or ask your system administrator.
