Hi, Some peoples related problems when run Interbase 6.5 under one DualCore processor. I have this problem then. In my case i have the Interbase 6.5 installed on the server (server with DualCore processor). The client machines load very slow, and in some machines the system don't load. My system access interbase via BDE. Any ideas is very welcome. Thanks Back to top Wayne Niddery [TeamB] Guest Posted: Thu Feb 01, 2007 1:56 am    Post subject: Re: Interbase under Dual Core problems ?

My system access interbase via BDE. Version of InterBase 6.5 and earlier cannot handle multiprocessor systems running Windows because Windows will continually switch the InterBase process from one processor to another. Check your IBCONFIG file and check that this statement is there: CPU_AFFINITY 1 (with no # in front). This was designed for multi-processor, so I assume it works with multi-core, but I'm not certain. This problem goes away starting with IB 7.0, so upgrading to the latest version (2007) would be the best solution. This entry for later versions can still be used to limit processor use, but InterBase can properly take advantage of multi-processors now. -- Wayne Niddery - Winwright, Inc (www.winwright.ca) "Nature abhors the vacuum tube." - J.R.
