On Informix, database server machines host the Informix chunk files (see informix_chunkfiles). The engine machine hosts the engine processes that access the file system portions or the Informix and file system portions of your system. Run the engine processes on the database server machine unless your site is running so many sessions that the engine sessions slow down the server unacceptably. The following table shows the minimum requirements for the server and engine machine. Your installation can require more than the amounts shown in these tables, depending on the number of simultaneous users you have.
