RE: SCO Open Server and Informix 7.3 - How far can I go with this platform??

We ran 500+ users, + 100+ ODBC connections on a Compaq 6000, 4x Pentium 200mhz, I Meg cache chips, {Cant remember if 1 or 2 Gig Ram}, Online 5, UNIXWARE 2.12. The box ran at about 80% Utilization. I Think with your box and UNIXWARE 7x + INFORMIX 7.x, with some tuning U should be able to handle 500 users easy. UNIXWARE 7 is supposed to be faster than SOLARIS on INTEL Platform. There was some issues about correct patches to load with some version of UNIXWARE 7.x and INFORMIX 7.x License issues is supposed to be a cross grade. -----Original Message----- From: Gary Quiring [SMTP:gquiring@netlabs.net] Sent: Thursday, March 30, 2000 3:03 AM To: informix-list@iiug.org Subject: SCO Open Server and Informix 7.3 - How far can I go with this platform?? I'm running Informix 7.3 on SCO OpenServer 5.0.5. We are using a Dell 6300 Server which has 4 Xeon 400mhz 1meg cache chips. The server has 4 gig of Ram and raid 5 10,000 rpm disks (Yes I know I need Raid 1+0). The server does order entry, financials, warehousing etc. for around 130 concurrent users. The question/problem is we bought a company and will be doubling the user count in coming months. The server is having problems related to kernel tuning when you do a netstat -m. We are having usocket errors and failures in mblks. SCO seems to have no answers but to blame it on Informix and we paid Informix to look at the system and basically blame it on SCO. Gee what a surprise! Bottom line is the server dies at least once a day and requires a reboot. Is Solaris 7 for the Intel platform a better solution? Do I really need to goto a UltraSparc platform? I priced out a 4 chip UltraSparc and was in the 250K area with DLT, 4 gig, 18 drives (18 gig each) and other stuff (rack, Veratas etc). The config is around 3 times more costly than a similiar Intel XEON server. I'm just looking for any input that some of you have had with the various platforms. Thanks Gary Quiring
