Antwort: Re: IDS 9.x stability on Solaris vs Linux

I see no reason to use Linux. It might be quite stable, it does not yet support Kernel AIO and does not have a good support for raw devices. Anyway you have always hassle with the distributions. An example: Hardware: 2way IBM x440 -> only supported Linux RedHat advanced server 2.1 Software: IBM DB2 and IBM Domino 6. This will not work because Domino 6 does not run on pre 2.4.18 Kernels and RedHat has a 2.4.9 Kernel. Or try one of the latest Suse Enterprise Servers. They will not work with informix because glibc is to new and not downward compatible. I'd recommend: stay with Solaris! A SunFire V480 is cheaper than a x440 and scales much better with more CPUs. And best of all no Problems with Server Software. Informix, Notes, DB2, Oracle they all just run. No new Kernel required, no hassle with glibc. Administring RedHat Advanced Server is a horror. You always have to use those graphical tools which don't give all the power of the underlying server software: example editing timezone and xntpd information. I ended up changing the startscript of the ntp daemon because that freaky gaphical Tool always destroyed my configuration. And at last: RedHat Advanced costs a lot of money: 2.100$ per Server. If you buy a SunFire Box the OS is included. regards Thomas -- General Logistics Systems Thomas Mieslinger German-Parcel-Str. 1-7 fon: +49 6677 17 463 36286 Neuenstein fax: +49 6677 17 111 Germany eMail: thomas.mieslinger@gls-germany.com Michael Mueller <michael.mueller01@kay-mueller.de> Gesendet von: owner-informix-list@iiug.org 01.07.2003 09:48 An: informix-list@iiug.org Kopie: Fernando Nunes <spam@domus.online.pt>, rkapur@mpr.org Thema: Re: IDS 9.x stability on Solaris vs Linux I agree with Fernando. Having worked inside the Informix support organization for a long time my experience is that the overwhelming majority of bugs are generic anyway. I am also convinced that Linux is a well supported and stable platform. I see no reason to choose Solaris only because Informix is developed there. As far as I know qa tests for the current development are run on a couple of platforms every night. Porting does not introduce new bugs in the first place. It often uncovers hidden generic bugs and makes a product more stable on all platforms.
