Database server and engine computer requirements

Your database server and engine computer must meet certain requirements.

On Informix®, database server computers host the Informix chunk files (see informix_chunkfiles). The engine computer 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 computer 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 computer. Your installation can require more than the amounts shown in these tables, depending on the number of simultaneous users you have.

Note: For the latest information about server resource requirements, see the Rational® Synergy Readme file.
