The Technical Articles section provides a wide variety of detailed technical content covering a wide area of material which has been written by our technical team members.
This article follows on from the earlier TPC-C benchmarking performed on IDS 12.10, if you missed it, you can read it here. This article takes a view on the topic of DIRECT_IO and its use within IDS, it also highlights the impact of file system caching on Linux, which is relevant for those editions of Informix where DIRECT_IO cannot be used.

If you’re building or fixing Informix ESQL-C applications then you’re almost guaranteed to come across the UNIX ‘make’ utility. This article describes a very simple Makefile for ESQL-C that can be adapted for many small projects.
