Informix 10.0 FC4 & Solaris 10
Hi all, We are in the process of moving our database from the old 7.31 to 10 on new Sun systems. There seems to be some disagreement between our system admins and informix DBAs concerning the correct configuration of the Solaris 10 OS. Mainly zones, projects and resource management. Are there any good sites out there that have examples of the correct way to set up zones, projects and resource management for use with informix? Thanks, Sam
Hi, I do not think there is a "correct" way to set up a Solaris 10 for Informix. If you have a dedicated server for one instance, there is no need to have multiple zones defined. We have some Solaris 10 machines running very good without any zone definition (dedicated to one instance of IDS). If you have other things running on the same machine, you might have a good reason to define zones and assign ressources. If you are running multiple instances of IDS on that machine, there might be a good reason to assign the ressources per instance (but you could also run multiple instances without zones and use informix parametes to limit resources access). Of course, disc layout plays a mayor role in the setup of a new system. Do you have a SAN, or mirrored local disks, maybe shared disks ? But all this depends on your intended environment. So it is hard to say which setup sou should choose. I think, you should first define what you want to do with the machines. Then look at the old machines and search for bottlenecks. Version 7.31 to 10 is also a step which should be considered. In version 10, you can have bigger chunks, and things like update statistics are different. There are many recommendations about this in this group, if you search the archives. I assume, you have more memory and more processor power in the new machines, so it is normally necessary to tune some parameters in comparison to the old setup. From sysadmin point of view, also security might be a point to look at. How are users/groups identified now ? Is the server somewhere behind an application server or is it accessed by some Windows machines directly and open to the LAN, maybe accessible by WAN ? If you think about zones, a non-global zone will always restrict IDS in accessing the given ressources. This might be intended and ok, but could also restrict the server to unwnated behaviour (noage and forced residency do not work in a non-global zone e.g.) I would setup an IDS instance always as dedicated server, but there are many reasons depending on your environment to set up with zones and resource assignment.
