1. Yes. Most likely, everything works under all flavors IF you go back to the source level and do your own compiles. You have to make sure you have the right level libraries etc. Also, some venders have only set things up for a limited number of distributions. Again, you can install things manually. Some products may not have been tested with other distributions or at some levels.
Some of it, no problem. Also, beware that some directory conventions seem to be different. A product might not find a compatable directory structure with another distribution. Just how much work do you want to do? 2. You really don't have to worry if you are LPAR or VM. Yes, you can test to see what you are running on. Just issue a CP command such as Q CPUID. If successful, you are under VM. There are a lot more legit ways of determining how you are running. But you really shouldn't need to know. 3. Too large for me to even hazard a guess. Tom Duerbusch THD Consulting >>> [EMAIL PROTECTED] 09/23/03 04:39PM >>> I'm researching porting an application to S/390 Linux and had the following basic questions: 1 - Do I need to be concerned about differences between Linux distributions? I.e. if I get it to work under SuSE will it work on RedHat or Debian assuming the kernel level is the same or compatible? Is the main difference in the administration/maintenance utilities provided with the package? 2 - Do I need to worry about whether the application runs in a VM or LPAR Linux configuration? If so, is there a way for my application to test which environment it is running in. 3 - Does anybody have any ideas when the number of disks available to Linux will be increased to a significant amount? For example, we have customers who would need 200+ 3380 devices to support our application if they wanted to import all existing information from MVS. I see that SuSE Enterprise Server 8 supports 600 disks, but do the other distributions support that many? ~~~~~ John Rowland Fischer International Systems Corporation www.fischerinternational.com 239 436 2751
